Title: Manually actuated dispenser
Inventor: CORSETTE DOUGLAS F
IPC: F04B9/14
Filed: 1984-10-06
Granted: 1989-03-08
Abstract: The pressure in an accumulation chamber (29) increases during the compression stroke of a plunger (31) to create a force in excess of the thrust of a return spring (50).  An accumulator (23) shifts away from the blind socket end (21) of the pump body (11), and its discharge valve (28) becomes unseated to open the discharge passage (14).  The discharge continues until the pressure in the pump chamber (33) is again overcome by the resilient force of the spring, closing the discharge as the accumulator returns to its original position in which its discharge valve is reseated to close the flow.  At the end of the plunger suction stroke, a container vent valve (48) closes the container vent.

Abstract: The circuit  supplies  the  carrier  frequency  of  audio  by indirect frequency method independantly to control  the  frequency completely when audio signal is not modulated. It includes a voice modulator (140) for modulating voice signal by indirect  frequency method, a mixer (150) for mixing the output of the voice modulator (140) and video carrier signal, a  voltage  controlled  oscillator (160) for generating carrier frequency  and  applying  it  to  the voice modulator (140), and a divider (180) for dividing the output of the VCO (160).
