Abstract: A drier comprising a pressure cylinder formed by two cylinder parts. One cylinder part has inlet and outlet flow fittings on it, for connection of the cylinder in the refrigerant circuit. The two cylinder parts further have passages in them for the flow of the refrigerant, and desiccant modules mounted in the passages to remove water from the refrigerant. The two cylinder parts are made of molded plastic and are round and cup shaped. The annular open sides of the two parts are attached together by a lug-in-groove twist lock connection. Further, the annular open sides have a scarf joint formed thereon, and the parts are bonded together at the joint to form a strong integral construction. A sight glass is provided at one end of the cylinder and a blow-out plug may be provided at the opposite end.

Abstract: An extrusion tube and fin heat exchanger includes two end plates and two tank caps. A plurality of parallel extrusion tubes is disposed between the plates and through the tank caps. A plurality of fins formed of aluminum sheet, folded back and forth, is disposed between the tubes and about the extrusions. A tank cover is sealed over the tank cap at each end. The parts are assembled by a vibration method.

Abstract: A "U"-shaped polar bracket mounted on an automotive engine block has two curved slots at each end. A polar extension having two legs of unequal length is attached to the polar bracket. An automotive accessory is connected to the apex or polar point of the polar extension. This combination of elements allows great flexibility in the mounting position of the automotive accessory.
