A couple of gear questions

Hello all, I was wondering a couple of things with gears:

Is the timing wheel (http://peeron.com/inv/parts/x480) a gear? Can two of them
interact with each other? What (other) uses does it have?

The 24-tooth clutch gear (http://peeron.com/inv/parts/60c01) seems to absorb
motion if it gets stuck. However, at least in the Cherry Picker (8292) the
clutch gear is almost right after the motor, before the worm screws... what is
that for?

Sorry to bother you with these but there are parts which's purpose I do not
understand...

(...) Add a light sensor, it can be used as a rotation counter. (...) (15 years ago, 9-Mar-09, to lugnet.technic)

(...) No, it is not really a gear. You might be able to get two of them to mesh, but I wouldn't recommend it. It is used on the Code Pilot (and elsewhere) to measure rotation speed along with a light. (...) The 24 tooth clutch is a torque limiter. (...) (15 years ago, 9-Mar-09, to lugnet.technic, FTX)
