Latest Patents
One of his latest patents is for a Container Refrigeration Unit. This transport refrigeration unit is designed for a transport container, featuring side-by-side evaporator and condenser compartments in the upper portion of the exterior frame. The power compartment extends across the entire width of the lower portion and contains an internal combustion engine, a motor-alternator, and a refrigerant compressor in an in-line relationship. The design includes a radiator coil and condenser coil that are inclined to receive air from a condenser fan. Additionally, the evaporator coil is positioned to project out of the plane of the rear face of the frame, with double inlet centrifugal fans to draw air from the upper part of the container. The unit also features separate panels for individual access to the evaporator and condenser compartments.
Another significant patent is for Eccentric Positioning Means for a Reversible Pump. This invention involves a spring-biased member that is positioned between the reversing eccentric and the rotor of a reversible, unidirectional flow pump. The member applies frictional torque to the eccentric from the rotor, driving it to the proper position. This design reduces wear on the contacting parts by maintaining a thin lubricant film between the member and the rotor face.
