Abstract: A system and method for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A variable speed drive pump is provided for pumping the flow of the mixture to the centrifuge. A computer responds to the output signals and controls the speed of the bowl and the conveyor as well as the operation of the pump to attain predetermined optimum operating conditions of the centrifuge.

Abstract: A centrifuge system and method according to which a conveyor is disposed in the bowl, and electrical motors are provided for rotating the bowl and the conveyor at different speeds. A DC bus is provided to store electrical energy which is supplied to the conveyor motor to rotate the conveyor if a brownout condition occurs. The bowl is braked in response to the brownout condition to generate electrical energy which is transferred to, and stored by, the DC bus for supplying to the conveyor motor.

Abstract: A system, method and computer program for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated at different speeds and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A meter is provided for metering the flow of the mixture to the centrifuge and generating corresponding output signals. A computer responds to instructions from computer programs and controls the speed of the bowl and the conveyor as well as the flow of the mixture and a diluting agent to the centrifuge in response to the output signals in a manner to attain predetermined predetermined optimum operating conditions of the centrifuge.

Abstract: A receiver/drier/filter for refrigerant having an aluminum cannister formed integrally with one end closed and an inlet tube and outlet standpipe extending through ports in the closed end and brazed therein with the external tube ends formed at right angles to facilitate external connection. A center tube is received over and sealed on the standpipe with a desiccant filled basket having a cover plate washer received over the center tube through the open end of the cannister as a subassembly. An aluminum cap is brazed over the open end of the cannister to seal the assembly. Alternatively, the basket and center tube are molded integrally of plastic.
