.~.~ Input and output exchange functions
DEFINITION
Classification: 74/810.2
Input and output exchange functions:
(under subclass 810.1) Subject matter wherein in response to the interchange of roles between the transmission input member and the transmission output member the path through which power is transmitted is changed.
(1) Note. To be placed herein the transmission must have a useful load at each of its input and output ends. Most of the patents herein disclose either motor-generators or motor-pumps used to start an engine which in turn drives the generator or pump.
