There ya go then! Please don't semi-quote Ronald Reagan. It's not becoming. I'm afraid that's just too 'in-American' for me. I actually haven't a clue what you are talking about ... If I'd been in a debate with Ronnie, and he'd pulled that "There you go, again" crap with me, I would have ripped him a new one, even if it cost me the election. And again - I'm afraid that's just too 'in-American' for me. I actually haven't a clue what you are talking about ... (This is way OT, but remember last year when Barney Frank ripped into a stupid woman who was griping about Obama being Moslem? I was proud to be queer. If all politicians -- conservative or liberal -- were that intelligent and quick witted, the level of political discourse in this country would be at a much higher level.) And again - I'm afraid that's just too 'in-American' for me. I actually haven't a clue what you are talking about ... Anyone from the UK would see it as a quick-fire throw-away line, and would laugh at it. It's sort of intended to be 'barbed', but not in a malicious way. It's a very hard to describe form of humour that is quite prevalent over here. I admire someone who can come up with quick throw-aways -- but unless they make them all the time, it's hard to tell they're supposed to be humorous. Not at all. As I said before, over here it works between people who don't know each other, provided that the circumstances of their encounter are correct. The whole point that I was making, and which you seem to have missed, is that I now know that that isn't the case, when it's cross-culture between the UK and the U.S. That's why you, like the original guy 25 years ago, see it as being offensive, I guess. I offended people with "innocuous" wisecracks so many times that I gradually became careful about what I said. A word to the wise...? Not needed. As I said in the first place, this was a long time ago when I was much younger, and my first encounters with Americans were on the telephone rather than face to face, and before I had the slightest understanding of what subtle cultural differences were, as opposed to the 'obvious' ones that I had encountered up to that point, which involved other European countries with a different language, vastly different food, a totally different outlook on life, and so on. If you cut yourself on barbed wire -- you're cut, regardless of how you came in contact with the wire. Hmmm. Not sure that I really understand the under-meaning of that one, either ... Arfa |

It's sort of intended to be 'barbed', but not in a malicious way. It's a very hard to describe form of humour that is quite prevalent over here. Arfa We have that kind of humor in the US too.. But only amongst friends or people you know fairly well. If a stranger uses sharp humor with me (some do) and It gives the feeling of you dont know me well enough to be poking humor at me, and we also usually take the fact there is ususaly truth in humor.. And honestly you probaly think the US standards are idioic and stupid to still be using when the rest of the world is using the metric system. Thats the feeling I get here in Japan at least. People cant understand why the US uses the old system still. Anyhow.. Just my $0.02 Yes. Knowing the U.S. and its people much better now, as I tend to visit twice a year and have now for many years, I would say that was pretty much spot on. Although I've found that American people are much more friendly in general to strangers, than people over here are, I also find that they are much more 'reserved' in actually getting to know them as a friend. Here in the UK, if you are just in the same business as one another, you tend to automatically think in terms of communicating with a 'kindred spirit'. So even on a first contact with someone, if you appear within a few sentences to be speaking the same language, it becomes quite acceptable to introduce a degree of 'chuminess' into the conversation such as calling the person 'mate' and such-like. Barbed humour between you is then immediately accepted, and is likely to get thrown back at you by the other person, and often gets deflected onto the company that you, or the other person works for. Having made the 'APF' comment to the guy, in my naivety, I was expecting him to just throw back a similar comment like " so what, then ? Your British threads are better than ours, are they ? :-) " Like I say, easy to cause unintentional offence, if you are not familiar with the country, and it's people and their cultural differences, even if they appear to speak the same basic language. Many countries in Europe speak English as a second language. If you speak it to a German for instance, in general, he will not understand British humour. Not likely to be offended by it. Just won't understand it. A Frenchman, will understand it, and be offended - or at least pretend to be ... OTOH, a Dutchman will both understand the humour, and give back as good as he gets. They seem to have a very 'English' understanding of the English language. I don't know why that should be, but I was once told by a Dutch guy that I had dealings with, that it was because they easily received UK television over there, so tended to watch a lot of British made drama and comedy programmes. I wonder if this will change now analogue TV is almost now all gone. I bet that they don't receive the digital multiplexes across the water, anything like as well as they did the high power analongue transmissions. Any Dutch people reading this care to comment ? Arfa I'm not Dutch but I do spend several weeks there every year and watch some Dutch TV almost every day. BBC1 and BBC2 are available on cable, but without teletext, apart from subtitles, so many viewers are exposed to British attitudes and humour. I imagine that that will continue after the digital switchover. There are also a lot of UK programmes and films on their own channels. Most keep the original soundtrack and are subtitled (not always accurately). Documentaries such as David Attenborough's tend to have Dutch speech when the presenter is off camera. Dad's Army was very popular there, to my surprise as I thought it was too British. Several other programmes have been made in Dutch versions, but not always successfully. The Dutch version of East Enders flopped, and their versions of Only Fools and Horses and The Kumars at No. 42 were simply dire. Their QI, HIGNFY and Who Do You Think You Are? have turned out well. In return for our sending them excellent programmes, they then sent us The Generation Game and Big Brother. Apart from having a basically different sense of humour, the Germans are not exposed to British humour to the same extent because their foreign programmes are almost always dubbed. I can't comment on how they correspond to the original soundtracks as I have never watched any British comedy on German TV, apart from the Monty Python German special years ago. Don't know about the French, but who cares about them anyway? -- Peter Ying tong iddle-i po! |

Not come across those on UK cars. Where you need a smaller head than standard, normally allen, torx or even one with curved sides which is an exact fit to the next size down bi-hex socket. Basically to make the head round or as near as possible to give maximum strength. A wrench in the UK usually means an adjustable spanner of some sort, so only used by amateurs. ;-) -- *Great groups from little icons grow * Dave Plowman London SW To e-mail, change noise into sound. |

I don't think Arfa is going to "blend" whether he uses your terminology or not, and I doubt that's his objective. But you wrote an awful lot of words without using "freeway," which is what we call the 101 here, and is the most common word for "interstate highway" throughout the midwest, as well. I'm not going to say unequivocally that it's widely used all over the U.S., because I don't know for sure, but I'd bet money on it. In cities with many freeways, they have to use more specific terms, but when there's only one, who needs a number? BTW, everyone I know in LA doesn't use numbers at all, but names that are meaningless to outsiders even if they have a map: "Ventura freeway," "Hollywood freeway," "Pasadena freeway," etc. |

I can't recall anyone not using this terminology in the 20+ years I've lived here, or the 30 + years I lived in Ohio. The only place I've been with no Interstate Highway was in Alaska. Everywhere else, they used the same terminology. -- You can't fix stupid. You can't even put a band-aid on it, because it's Teflon coated. |

I can live with having too many screws because half of them are usually stripped out and the remainder hold things together. What bugs me are snap together clamshell cases, such as LCD monitors and TV's, where you have to remove a mess of screws *AND* pry the case apart. While snap together plastic is probably easier to assemble because it doesn't require much fixturing to position the robotic screwdriver, it does suggest that the case was never intended to be opened or the unit repaired. I recently repaired a Yamaha P70 electric piano. I didn't count, but I'll guess about 60 large "sheet metal" type screws holding it together. I don't use an electric screwdriver, but this is one time that I wish I owned one. Even with switching hands, my hands ached after I as done. The problem with such "sheet metal" screws is that they offer high frictional resistance on every turn, while more conventional screw threads, only offer high resistance when tight (or smeared with thread lock). My guess is the large number of screws was to prevent mechanical resonances in the plastic case or to keep them from falling out from vibrations. Still, metal thread inserts, screw threads, and steel nut plates, would have been much easier to handle. On the silicon grease front, I agree with most of the comments. Thin works much better than globs of silicon grease. One should remember that the purpose of silicon grease is NOT to bridge gaps. It's to fill in the surface roughness, groves, and crevasses. Most of the heat transfer is metal to metal contact, not through the silicon grease. In a past life, I used to design marine radios. The problem was that the power xsistor packages of the day (1970's) were generally thermal disasters. Either there was insufficient contact area to obtain sufficiently low thermal resistance, or they were not flat. I solved the first by building pyramid like structures of copper washers to act as a heat spreader. I solved the latter by polishing the mounting base of the power transistors on fine emery cloth. I hated to polish away the gold plating, but that's what it took to get the heat out. I made numerous tests and measurements trying to determine the optimum amount of silicon grease, and eventually concluded that ultra thin is best. Instructions were to smear a tiny amount onto the area, and then wipe ALL of it off with a plastic scraper. What remained was silicon grease in the remaining surface roughness, which was all that was necessary. I recently repaired an IFR-1500 service monitor. The power supply section was intermittent. The 0.062 aluminum power supply case, was butted up against the large aluminum heat sink that covered the entire rear panel. In between was a huge amount of silicon grease. The sandwich was held together by two large 10-24 screws, which probably explains the silicon grease overdose. Two screws is not going to bend the aluminum case so that it lays flat. So they tried to fill in the lack of flatness with silicon grease. That doesn't work. It took me considerable effort and alcohol to clean up the mess, but I still managed to get it all over everything on the bench. After the repair (large copper wires on torroids were not soldered properly), I reassembled it with only a little silicon grease around the two large screws, and left the rest to it's own devices. Works fine with no obvious overheating (checked with an IR thermometer and thermocouple probe). My guess is all that silicon grease did nothing useful. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

I was talking on the phone to one of the designers of a piece of equipment that we sold here in the UK, and asked the guy if he could arrange to send me some screws for the cabinet, as they were a thread that we didn't readily get over here. He asked if I knew exactly what size they were so I replied, quick as a flash, thinking that I was being funny, "I guess that they are round about 3/16ths APF." "What's APF ?" the guy asked. "American **** Fit", said I ... Stony silence on the phone. Half an hour later, I was summoned to the boss's office. Apparently, the guy had been really offended by this, thinking that it was a slur on what he considered to be good American engineering, and had called my boss to complain about me.

(One can easily spot newcomers to San Francisco who refer to "the 80" or "the 101". That's just SO wrong!) Ahem. I beg to differ slightly. In the People's Republic of Santa Cruz, it's called "Highway 9", "Highway 17", and "Highway 1". They're never referred to by their correct name of "US Route 9", "State Route 17", and "Calif State Route 1". In Smog Angeles, Hwy 1 is called "Pacific Coast Highway", State Route 90 is the "Richard M. Nixon Freeway", and Interstate 5 is called the "San Diego Freeway". When I lived over the hill in San Jose in the late 1970's, the numerical designations were rarely used. Interstate 880 was called "the Nimitz". These days, nobody remembers Admiral Nimitz so it has become "880". Caltrans seems to be making a concerted and expensive effort to add to the confusion by numbering all the freeway exits and onramps. Unfortunately, they didn't plan it very well, so some of the numbers are already out of sequence and there are postfixes such as "Exit 11c". I have yet to hear anyone refer to a specifically named exit by its numerical equivalent. When one visits the People's Republic of Santa Cruz, the point of entry is what is called "the fish-hook" because of a 270 degree tight turn. It's been greatly improved by an expensive rebuild 4 years ago, but it still offers a fair approximation of a roller coaster ride: http://we.got.net/~mapman/streets/SantaCruz/Fishhook/fishhook.html My office is adjacent to this abomination. I would estimate we lose one large truck to the tight turns every 2 weeks. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Here in BC, Canada and (it appears) the Pacific Northwest states the US highways are called Ixx - I5 being the main north-south one. Well, they're actually called that everywhere in the US, at least officially and on maps. But what do *people* in that region actually call them?

While snap together plastic is probably easier to assemble because it doesn't require much fixturing to position the robotic screwdriver, it does suggest that the case was never intended to be opened or the unit repaired. I recently repaired a Yamaha P70 electric piano. I didn't count, but I'll guess about 60 large "sheet metal" type screws holding it together. I don't use an electric screwdriver, but this is one time that I wish I owned one. Even with switching hands, my hands ached after I as done. The problem with such "sheet metal" screws is that they offer high frictional resistance on every turn, while more conventional screw threads, only offer high resistance when tight (or smeared with thread lock). My guess is the large number of screws was to prevent mechanical resonances in the plastic case or to keep them from falling out from vibrations. Still, metal thread inserts, screw threads, and steel nut plates, would have been much easier to handle. On the silicon grease front, I agree with most of the comments. Thin works much better than globs of silicon grease. One should remember that the purpose of silicon grease is NOT to bridge gaps. It's to fill in the surface roughness, groves, and crevasses. Most of the heat transfer is metal to metal contact, not through the silicon grease. In a past life, I used to design marine radios. The problem was that the power xsistor packages of the day (1970's) were generally thermal disasters. Either there was insufficient contact area to obtain sufficiently low thermal resistance, or they were not flat. I solved the first by building pyramid like structures of copper washers to act as a heat spreader. I solved the latter by polishing the mounting base of the power transistors on fine emery cloth. I hated to polish away the gold plating, but that's what it took to get the heat out. I made numerous tests and measurements trying to determine the optimum amount of silicon grease, and eventually concluded that ultra thin is best. Instructions were to smear a tiny amount onto the area, and then wipe ALL of it off with a plastic scraper. What remained was silicon grease in the remaining surface roughness, which was all that was necessary. I recently repaired an IFR-1500 service monitor. The power supply section was intermittent. The 0.062 aluminum power supply case, was butted up against the large aluminum heat sink that covered the entire rear panel. In between was a huge amount of silicon grease. The sandwich was held together by two large 10-24 screws, which probably explains the silicon grease overdose. Two screws is not going to bend the aluminum case so that it lays flat. So they tried to fill in the lack of flatness with silicon grease. That doesn't work. It took me considerable effort and alcohol to clean up the mess, but I still managed to get it all over everything on the bench. After the repair (large copper wires on torroids were not soldered properly), I reassembled it with only a little silicon grease around the two large screws, and left the rest to it's own devices. Works fine with no obvious overheating (checked with an IR thermometer and thermocouple probe). My guess is all that silicon grease did nothing useful. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com I suspect we are as engineers are just as likely to be mislead by manufacturer's claims as joe public and general ads. I could not convince myself that silipads were better than mica (no patents so litterally dirt cheap) - so experiment called for. These days I own a matchbox size remote IR pyrometer and would use that to compare device body temps in before and after situations , not fingertips Mica versus Silicone pad insulators I was not convinced that for an existing used amp with 4x TOP66 power output devices that the silipads were better than mica. Each of the 4 white insulating pads had shrunk about 5mm at the tops (hottest) compared to bottoms , ruffling the original outer edges, heat damage ?. I'm wondering if they can chemically change over time and/or excessive temperature , downgrading to be more of a thermal insulator. They are not discoloured or hardened or anything different in the ex-compressed area by sight or flexing, just permanently deformed , the ruffling is permanent. I replaced all 4 with mica and thin films of thermal grease. Before doing so I powered up the amp with 400 Hz continuous sine giving 20 watts in a dummy load. No fan cooling for this amp, just convection/radiation. Laid a brass barrel protected thermometer on the heatsink and took measurements. Stabilised at 33 deg C over ambient after 50 minutes. Replaced with mica and redid the load test. For same ambient , same testing position/attitude, power in load etc it now took 30 minutes to stabilise at plus 32 deg C over ambient. More graphically , but less scientific, - the finger test. After half an hour of heating with the mica setup I could hold a fingertip on each tranny for about 5 seconds before finding it uncomfortable. Previously half a second of fingertip touch was enough. I think I will rely on the evidence of my own observations and not performance tables produced by the manufacturer's with an obvious vested interest. I've no reason to believe the original silipads had aged, been affected by WD40 or anything. I will assume they are , all manufacturers, all generically bad until a similar personally conducted experiment, in a real situation, proves to me to be otherwise. |

Uses intermediary Al block between immediate o/p h/s plate and chassis. White goo on both surfaces is still as placed, not splurged out. Failure to fettle/de-burr the post machining raised rims around the machined holes so acting as thin washers so heat just going through the 3 bolts not body of Al. Amp failure nothing to do with this poor heatsinking |

Jeff, that's just because you haven't figured out how to charge your customers to "run" wireless connections. :-) Geoff. I don't get many calls to "install" a wireless router or bridge. However, almost all my wireless work is cleaning up the mess made by someone else. Commodity wireless is sufficiently simple that almost anyone can do it if they follow instructions. Making the decision whether wireless is appropriate is not so simple. Wireless for laptops, PDA's, game consoles, some printers, and wi-fi phones are appropriate. Tivo, Netflix, Blue-Ray players, desktops, and other high bandwidth devices are not. The nice part of this cleanup type of work is I can charge almost any fair price. I can't do that on an initial install. Incidentally, the reason I didn't want to run wires any more is that I was taking statins to reduce cholesterol for the last 8 years. The side effect was ever increasing back aches. They were tolerable for the first 5 years, but continued to get worse until I was unable to do many things. I stopped taking statins about a year ago, and had to wait 6 months for the back aches to mostly go away. I'm now trying to get back into shape so I can again crawl around under houses running wires. Meanwhile, it's a good excuse to not get dirty. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

(One can easily spot newcomers to San Francisco who refer to "the 80" or "the 101". That's just SO wrong!) Ahem. I beg to differ slightly. In the People's Republic of Santa Cruz, it's called "Highway 9", "Highway 17", and "Highway 1". They're never referred to by their correct name of "US Route 9", "State Route 17", and "Calif State Route 1". In Smog Angeles, Hwy 1 is called "Pacific Coast Highway", State Route 90 is the "Richard M. Nixon Freeway", and Interstate 5 is called the "San Diego Freeway". When I lived over the hill in San Jose in the late 1970's, the numerical designations were rarely used. Interstate 880 was called "the Nimitz". These days, nobody remembers Admiral Nimitz so it has become "880". Caltrans seems to be making a concerted and expensive effort to add to the confusion by numbering all the freeway exits and onramps. Unfortunately, they didn't plan it very well, so some of the numbers are already out of sequence and there are postfixes such as "Exit 11c". I have yet to hear anyone refer to a specifically named exit by its numerical equivalent. When one visits the People's Republic of Santa Cruz, the point of entry is what is called "the fish-hook" because of a 270 degree tight turn. It's been greatly improved by an expensive rebuild 4 years ago, but it still offers a fair approximation of a roller coaster ride: http://we.got.net/~mapman/streets/SantaCruz/Fishhook/fishhook.html My office is adjacent to this abomination. I would estimate we lose one large truck to the tight turns every 2 weeks. -- Jeff Liebermann Interestingly, here in the UK, the exits from the motorways - loosely 'freeways' equivalent, I guess - have always been numbered, and have always been referred to by number. So someone giving directions might say "take the M1 north, and exit at junction 15 onto the A508", 'A' being the designator for a major road, but without motorway status. Arfa |

Arfa California is different: http://en.wikipedia.org/wiki/California_Numbered_Exit_Uniform_System http://www.cahighways.org/num-exitnum.html A suffix letter A, B, C, D or E is used on multi-exit interchanges, or on multiple interchange exits within the same exit number zone.
