Patent number: 5195333Abstract: A refrigerant reclaim system includes a compressor, a heat exchanger, an oil separator, a condenser, a chill tank, a filter-dryer and a cooling coil in the chill tank. Refrigerant to be reclaimed is drawn through the cold side of the heat exchanger, converted to a gas which is discharged into the oil separator where the gas is directed upwardly in an expanding stream. The flow of the stream is abruptly interrupted to separate oil from refrigerant. The gaseous refrigerant is passed from the oil separator through the compressor, the hot side of the heat exchanger, a condenser and into the chill tank in a liquid state. Liquid refrigerant flows from the bottom of the chill tank through a filter-dryer, an expansion device, converting it to gas, through a cooling coil, submerged in liquid refrigerant in the chill tank, into the stream exiting the oil separator and back to the compressor.Type: GrantFiled: March 31, 1989Date of Patent: March 23, 1993Inventor: Leon R. Van Steenburgh, Jr.

Patent number: 5150515Abstract: An improved wheel alignment system and method is disclosed. This invention is a kinetic alignment system combining a geometric wheel aligner which measures toe angle with reference to the sidewall of a tire, and a dynamic wheel aligner which measures toe and camber angles with reference to the tread of the tire in order to rapidly and simultaneously measure both the position of a vehicle's wheel and the roll of the tire associated with the wheel. The geometric aligner of this invention includes (a) an improved pivot assembly that reduces scrub and the corresponding false position readings that otherwise result from the scuffing of the geometric apparatus across the sidewall of the tire when the wheel's plane of rotation changes, and (b) an improved striker assembly so as better to strike the sidewall of a tire at the tire's center line and, where the exact center line is missed, to self-correct for the unbalanced tire forces resulting from the missed strike.Type: GrantFiled: March 12, 1991Date of Patent: September 29, 1992Assignee: Merilab, Inc.Inventors: M. Stanley Merrill, Thomas B. Chapin
