Abstract:
A regulated power supply in which voltage from an AC power line is supplied through a power-regulating element, such as an SCR device, to a rectifier section whose DC output is supplied to a load. A relatively small sensing voltage, linearly reflecting current or voltage changes in the load circuit, is applied through a linear amplifier to the base of a proportional control transistor circuit. The sensing voltage, combined algebraically with a reference voltage is also applied to the emitter to produce in the collector output circuit a feedback voltage which is linearly proportional to the sensing voltage throughout a broad range. The feedback voltage is applied to the regulator element to adjust the output of the supply so as to compensate for said changes in the load circuit and thereby maintain a constant DC output.
Abstract:
A rotary internal combustion engine including a stator having a circular chamber within which is coaxially disposed a shaft supporting an off-center circular rotor, the diameter of the rotor being such that the distance between the center of the shaft and the zenith on the rotor periphery is substantially equal to the radius of the chamber whereas the distance between the center of the shaft and the nadir on the periphery is substantially equal to half this radius. Extending into the chamber are slide plates which are urged into continuous contact with the rotor surface to divide the chamber into operating zones of varying volume into which fuel charges are admitted for compression and ignition to produce gas expansion creating torque forces, the spent gases being exhausted from the zones. The slide plates are fully sealed to prevent gas leakage and are hydraulically interlinked whereby the plates engage the rotor with a constant pressure.
