Abstract: A removable self-contained refrigeration unit is mounted within a vehicle, and is removable from a vehicle as a unit. The casing mounts both the evaporator and the condenser, and in one embodiment also mounts the compressor. With the embodiment that mounts the compressor, no refrigerant lines need be found anywhere except on the casing. The casing is removable from the vehicle as a one piece unit merely by connecting or disconnecting electrical connections. In a second embodiment the compressor is mounted remotely from the casing but the evaporator and condenser are still changeable as a one piece unit. In this embodiment a refrigerant connection need also be connected or disconnected to change the unit.

Abstract: An intelligent air-condition system that detects the signals of the temperature distribution among the environment by using the infrared radiation, especially detects the location of the human-body temperature signals. Hence, according to the detected signals, the gas(es) for air-conditions can be firstly transmitted into the location where the human-body temperature signals exist, or be firstly transmitted into where the local temperature is urgent to be adjusted. Besides, the transitions of the gas(es) can be paused or stopped while there is no human-body temperature.

Abstract: A beverage container including a body and a lower cap having a cooling element mounted thereon that extends into an interior portion of the body.

Abstract: A steam trap with a closure element or valve disposed on the low pressure side cooperating with a valve seat, the valve being actuated by a control unit disposed in the high pressure chamber of the steam trap. The control unit includes a plurality of bimetallic spring elements each having a support portion and an operative portion and different actuation temperatures which act on the valve stem to close the valve on the valve seat. The support portions of the bimetallic spring elements engage a stationary support of said steam trap and the operative portions thereof engage the valve stem. The engagement of the bimetallic spring elements with the valve stem is such that when the valve is closed by the action of the bimetallic spring elements having the higher actuation temperatures, the bimetallic spring elements having the lower actuation temperatures are unaffected thereby and thus not stressed by the spring forces of the bimetallic spring elements of the higher actuation temperatures.
