DEFINITION

Classification: 60/39.2

(under subclass 39.01) Plants in combination with means to vary the rate of power output, as by varying the speed of the power output motor, or by controlling the temperature and/or quantity of the motive fluid, or by varying the duration of the events, during each cycle, of an intermittent combustion type generator.

(1) Note. In order to be classified in this subclass the patent should claim the control means more specifically than merely as a "valve", "valved pipe", "controlling means", "throttle valve", or similar broad terms. This exclusion note applies only to this subclass, and not to the indented

subclasses.
