Abstract: A freezer system is disclosed comprising a freezing mechanism and an adjacent freezer cabinet. The freezer mechanism has a compressor that produces hot gas refrigerant, a condenser, and an evaporator which accumulates ice on its outside surface. An evaporator condensate pan is mounted beneath the evaporator and a compressor condensate pan is mounted beneath the compressor and connected by a conduit to the evaporator condensate pan. A condensate pan heater coil is attached to the bottom of the evaporator condensate pan. A hot gas valve connected between the compressor and the condensate pan heater coil, when activated, conducts hot gas refrigerant to the condensate pan heater coil to heat it and thereby heat the attached evaporator condensate pan, which in turn heats the outside of the evaporator to help melt accumulated ice. The hot gas refrigerant is then fed from the condensate pan heater coil to the evaporator, heating the inside of the evaporator and fully melting the ice.

Abstract: A refrigerator system having a refrigerating mechanism packaged in a separate case from the refrigerated cabinet and adapted to be attached to either side of the refrigerated cabinet. The refrigerated cabinet has discharge and return openings on each of opposite sides. The refrigerating mechanism has matching discharge and return openings on each of opposite sides. The discharge and return openings on the unattached side of the refrigerating mechanism and refrigerated cabinet are covered. The refrigerating mechanism has an evaporator blower which draws warm air through the return opening in the attached refrigerated cabinet, then through a cooling evaporator coil to propel the cooled air into a blower plenum, and then out a discharge outlet of the blower plenum directly into the matching discharge opening in the adjacent refrigerated cabinet.

Abstract: A refrigerator cabinet is disclosed comprising a metallic cabinet case having a door opening in the front, a metallic cabinet liner mounted on the inside and thermal insulation separating the cabinet case and liner. A door is hingedly connected to the front of the cabinet case and adapted to swing over the door opening. A plastic cabinet thermal breaker is mounted between the metallic cabinet case and the metallic cabinet liner and frames the opening. A removable metallic breaker cap snaps on and covers the outside of the plastic cabinet thermal breaker except for a front facing portion of the plastic thermal breaker. A plastic door thermal breaker is mounted along the outer edge of the inside of the door and has an outwardly extending compressible portion which is adapted to press against the front portion of the plastic cabinet thermal breaker when the door is closed.

Abstract: The invention described is a process of and an apparatus for recognizing the size, location, orientation etc. of an object without human intervention. The convolution technique is used to solve the field theory equations to generate linearity signals characteristic of points in the optical image of the object. The linearity signal is perception of linear or strip-like features in an image. The recognition is achieved by analyzing the linearity signals.
