Do paternosters keep the car the same way up or do they invert it as it goes
over the top? Or are there two different sorts, with the added fun being "is
this the inverting sort?".

I imagine that paternosters are good where some people are going to all the
floors and therefore a conventional lift would have to stop at each (with
deceleration and acceleration at each floor), but are very slow if most of
the people are going from the ground to the top floor, and therefore the
paternoster has to go slowly (for safety of people who might have been
getting on/off at each floor) where a conventional lift could accelerate to
a faster speed when bypassing the intermediate floors. And also they are not
good if a lot of people want to get on/off and have to all do so within a
fairly small window of time while the lift floor is still within jumping
distance of the building floor.
