Re: clocks, I think that Telechron came up with the self starting clock. These older clocks usually have a power failure indicator window that shows a red dot when power is lost, reminding you that the clock may need to be reset. The Hammond organ company began as the Hammond clock company and refused to make a self-starting clock, claiming that you would not want it to restart and perhaps display the wrong time. The synchronous motors are also used in the organs for the tone generator: you use an induction motor for starting to "turn over" the sync. motor.
