Abstract: A control unit for an air conditioning system for a motor vehicle calculates a target blowing air temperature based on a temperature of a passenger's clothing detected by a no contact temperature sensor. An air conditioning operation is performed based on the calculated target blowing air temperature. In particular, when calculating the target temperature in the summer or in the winter season, a change of the detected temperature of the passenger's clothing is used, so that the change of detected temperature is reflected in the target temperature with a time delay.

Abstract: A conveyor for moving hot material at temperatures on this order of 1000° F. or higher along a trough receiving the material has one or more cooling liquid flow vessels extending over but spaced from the outer surface of a trough inner wall to indirectly cause cooling of the inner wall. A heat transfer connection conductively interconnect the vessel and the inner trough wall such as interposed thin webs or plates, or alternatively a mass of conductive beads interposed to controllably transfer heat into the cooling liquid flow vessel. A series of wear plates are clamped to a pushing side of a helical tube of an auger type conveyor, which tube can also receive a flow of cooling liquid. The arrangement of a mass of conductive beads is usable in other applications to provide a non rigid mechanical support of a controlled thermal conductivity.

Abstract: A door mounted dispenser for a refrigerator includes rear and opposing side walls that collectively define a cavity, a release mechanism for dispensing ice and/or water and a light for illuminating the cavity. The cavity light can be operated in one of three distinct modes, i.e., in a first mode wherein the cavity light is continuously illuminated, in a second mode wherein the cavity light is illuminated only through activation of the release mechanism, and in a third mode wherein the cavity light is illuminated based upon a sensed level of ambient light present at or near the refrigerator. In the third mode, the cavity light is illuminated at a first level based upon ambient light and a second, higher level when the release mechanism is operated. The level of ambient light necessary to activate the cavity light can be set by a consumer through control panel inputs.
