Abstract: Method and apparatus for controlling the operation of a motor driven compressor which is automatically unloaded when the receiver pressure reaches a predetermined maximum level and loaded when the receiver pressure reaches a predetermined minimum level by means of pressure actuated electric control means which are time delayed to start and stop the compressor motor and the unloading and loading operation in accordance with predetermined mode of operation. The compressor driving motor is controlled to stop immediately upon the receiver pressure first reaching the maximum pressure level whereupon time delay circuit means starts to measure a time interval during which the motor upon having been restarted in response to a restart pulse is prevented from further stoppage each time the maximum receiver pressure level is reached subsequent to the first, whereby the compressor can be brought on load immediately in response to demand for working medium during the measured time interval and whereby overheating of the motor between subsequent stoppages and restarts is avoided. Upon expiration of the measured time interval, the motor will stop running until the minimum receiver pressure is reached, unless the compressor should be on load at such time, in which case the motor will continue running until the compressor again is unloaded upon reaching the maximum receiver pressure level, whereupon the aforementioned cycle is repeated.

Abstract: A low liquid volume retort system is provided with a tunnel disposed within and spaced from the side walls and cover of a retort. A plurality of spaced containers are loaded in the tunnel, and a liquid maintained at a temperature different from that of the containers is then pumped from an inlet end of the tunnel to the outlet end to completely fill the tunnel and to evenly transfer heat between all of the containers and the liquid. The liquid then overflows from the outlet end of the tunnel and gravitates to the lower portion of the retort for return to a desired processing temperature and recirculation through the tunnel. The quantity of liquid required for processing is greatly reduced by filling only the tunnel with liquid, and collecting only a small portion of the liquid at the bottom of the retort before again recirculating the liquid through the tunnel and past the containers therein being processed.

Abstract: An alternating current machine drive system, comprised of an alternating current machine and an inverter configured of a plurality of pairs of transistors with the transistors of each pair coupled in series-aiding fashion and each of the pairs of serially coupled transistors connected across a direct current source, is controlled in accordance with inverter current. The transistors of each inverter transistor pair are alternately rendered conductive to supply alternating current at the inverter output in accordance with a current error signal, proportional to the difference in magnitude between actual inverter phase current and a sinusoidal reference signal, with the conduction state of the transistors of each pair reversing each time the current error signal exceeds an upper and lower hysteresis limit, which limits vary in accordance with actual inverter phase current. Conditioning of inverter output voltage to control machine speed and torque is achieved by varying the sinusoidal reference signal frequency and amplitude, respectively, in accordance with operator commands. Optimum inverter machine drive performance is achieved by regulating the sinusoidal reference signal amplitude and frequency in accordance with a feedback machine torque signal and a feedback machine flux signal, respectively.

Abstract: A pressure gas ventilated pressure suit comprises a suit adapted to cover a person which includes a head portion with a face encompassing part which defines a breathing space in front of the person's face and which also includes a body portion defining a pressure space around the person's body and parts of the person's head which is separate from the breathing space. A connection is established between the breathing space and the pressure space through a check valve which permits inhaling of the air found in the pressure space through the breathing space to the wearer. The pressurized breathing gas is connected to discharge gas into the pressure space to maintain it at a predetermined pressure which advantageously provides an inflation of the body portion of the suit. During breathing the wearer inhales in the breathing space and pulls in some of the air from the pressure space through the check valve. The air is exhaled through an exhaling valve connected into the breathing space. The suit advantageously provides a device for adjusting the pressure in the body portion through the regulation of a pressure regulating valve which is connected to the discharge of a compressed air tank.
