Abstract: A power electronics based system using natural, convection cooling, includes an enclosure housing a plurality of discrete components distributed in a vertical direction from a bottom portion to a top portion of the enclosure and having a heat density weighted average center at a first height along the vertical direction. There is a heat exchanger adjacent to the enclosure, including an inlet port and an outlet port in fluid communication with the enclosure. The heat exchanger has a vertical cooling average center at a second height. There is a cooling fluid disposed in the enclosure and in the heat exchanger to cool the discrete components. The discrete components are positioned in the vertical direction in the enclosure such that the first height of the heat density weighted average center along the vertical direction is below the second height of the vertical cooling average center of the heat exchanger.

Abstract: A machine for tenderizing meat. Said machine includes a textured roller and a smooth plate between which untenderized meat is fed for tenderizing. Pressure is applied to the untenderized meat as it passes between the roller and plate thereby tenderizing and flattening the meat to the desired thickness and texture.

Abstract: A motor control system and the electrical bus for interconnecting the components of the control system are disclosed herein. The system includes a main motor control unit connected to four motor axis control modules. The control algorithms and commands for the system are stored and executed by the control unit which communicates control commands to the individual motor axis control modules. Each motor control module processes the control commands to control a motor connected to the module, and also communicates feedback signals produced at the associated axis to the control unit. The interconnection between the control unit and the modules is positioned at the face of the components to facilitate removal and insertion of the modules. The electrical bus includes both communications conductors and power conductors, and is included in the interconnection of the components.
