an improved electrical resistor
 

Middle sentence of second paragraph is the most relevant.


Otis Frank Boykin was born in 1920 in Dallas, Texas. His mother was a
homemaker and his father was a carpenter. He worked as a laboratory
assistant at the nearby University's aerospace laboratory. Otis
attended Fisk University and Illinois Institute of Technology, but
dropped out after two years because his parents could not afford his
tuition.

Boykin, in his lifetime, ultimately invented more than 25 electronic
devices. One of his early inventions was an improved electrical
resistor for computers, radios, televisions and an assortment of other
electronic devices. Other notable inventions include a variable
resistor used in guided missiles and small component thick-film
resistors for computers.[2]

So how can one improve an electrical resistor?

A careful read of the actual patent filed for this "improved resistor"
shows that the improvement was more for reliability and ease of
manufacture. This also implies that the cost would be minimized for
the more accurate resistors (1% etc).
Search the web for patent #2972726 for more details. The patent
itself is 4 pages and was dated 2/21/1961.

Stability and tolerance comes to mind.

!:better stability
2:lower temperature coefficient
3:mechanically stronger.
4:Less ageing.
5:higher admissable peak voltage/current.

Warn us when you produce something like that.....

The invention was easier to manufacture while simultaneously lowering
both self-inductance and self-capacitance.

A change of materials might allow a resistor of a given physical
size to dissipate heat more effectively, or run at a higher body
temperature without damage or change-of-value, or survive a
catastrophic fault better (e.g. "flame-proof" construction), or be
less expensive to manufacture.

This is a bit misleading, because Boykin was a grad student at IIT
from 1946 to 1947. Around that time, he formed the Boykin-Fruth
corporation with fellow inventor Hal Frederick Fruth, PhD. (Dr. Fruth,
a physicist, was perhaps best known today for telling W. Edwards
Deming that Western Electric might pay him as much as $5000 a year
when he got his PhD, but that they were looking for men who would be
worth $50K a year to them.)

I must have really low standards if I didnt think of any of these.
My ex-girlfriend tells me that's what I have.

Okay.

So he had graduated from Fisk. Yes, definitely misleading. Although
now I do see that it could mean what you say , I thought he only had
two years of post-high school. Six years is a lot more. Wikipedia
often has paragraphs out of chronlogical order and hard to follow, or
even conflicting paragraphs, written by different people, I guess.

Around that time, he formed the Boykin-Fruth
corporation with fellow inventor Hal Frederick Fruth, PhD. (Dr. Fruth,

Hmmm.

Thanks all.

Boykin was black, btw. Fisk is a historically black college.

Did you trade up to a girlfriend of a higher standard? ;-)
