Abstract: A light bar assembly mounted on the roof or rear door of an emergency vehicle. The assembly includes a light bar support shaped for the particular make and model of a vehicle on which the assembly is installed or alternately a support configured for mounting on two or more different vehicle models. The support has openings formed in it, each corresponding to the location of a preexisting opening formed in the vehicle for electrical wiring and mounting fasteners that can be used to attach the support to the vehicle so that no additional openings or other alterations are required. This allows the light bar assembly to be readily mounted on the vehicle without modifications to the vehicle or the assembly being required. Lights are mounted on the support. The lights are selectively illuminated in accordance with the use of the vehicle in emergency or other situations.

Abstract: A refrigerant recovery system for recovering refrigerant from a cooling system is disclosed. A compressor (60) is provided having an oil drain outlet (66). An oil separator (50) is also provided for receiving incoming refrigerant before the refrigerant is drawn into the compressor (60). The oil separator has a helical coil (90) disposed in a heat exchange relationship with the oil separator (50) for receiving the refrigerant after the refrigerant is compressed by the compressor (60) and thereby cooling the refrigerant. A condenser coil (92) is also provided for receiving the refrigerant after the refrigerant has passed through the helical coil (90) and further cooling the refrigerant, causing it to condense. An aluminum base (100) is provided for dissipating heat from the condenser coil (92) and the oil separator (50) since the condenser coil (92) and the oil separator (50) are mounted directly on the aluminum base (100).
