US Patent:

46241124, Nov 25, 1986

Filed:

Aug 26, 1985

Appl. No.:

6/769961

Inventors:

Robert H. Proctor - Baltimore MD

Assignee:

Murray Corporation - Cockeysville MD

International Classification:

F25B 4500

US Classification:

62149

Abstract:

An air conditioner charging station includes oil and refrigerant reservoirs, a vacuum pump, and an electronic sequencing unit. A header conduit connected to the reservoirs and vacuum pump is connected to a cross-over conduit, which in turn is connected to conduits extending to the high and low pressure sides of an air conditioner compressor. Electrically operated valves are provided in the cross-over conduit, in a dump conduit connected to the cross-over conduit, and in branch conduits connected to the reservoirs and to the vacuum pump. An over-ride control of the cross-over valve is provided, responsive to the pressure of the high pressure side and an over-ride control is provided for cross-over valve, activated if the ambient temperature is below a predetermined level. An excessively high pressure in the high pressure side causes the closing of the valve in the refrigerant reservoir branch conduit.

Assignee:

Murray Corporation - Cockeysville MD

International Classification:

F16L 3700

US Classification:

285 39

Abstract:

A quick-disconnect coupling for a pair of telescopic slidable tubular members has an annular garter spring trapped in a spring housing carried by one of the tubular members. The garter spring is adapted to be lodged between a right-angularly disposed flange on the spring housing and an upwardly-inclined annular flange formed on the end of the other tubular member. The respective flanges are arranged transverse to each other. The components of the coupling are formed conveniently and economically, without the necessity for expensive metal-forming dies, and are easily assembled.

Appl. No.:

7/621276

Inventors:

Robert H. Proctor - Baltimore MD

Assignee:

M/E Automotive Corporation - St. Louis MO

International Classification:

B01D 1900
B01D 3518

US Classification:

210774

Abstract:

A highly efficient refrigerant purification device for removing moisture, oil, particulates, non-condensible impurities and other contaminants from a refrigerant, thereby allowing maximum recovery of the refrigerant in a refrigeration system, the refrigerant being in full compliance with regulatory standards. The device can be easily adapted to purify a wide variety of refrigerants, and the device is organized in a logical arrangement which utilizes a minimum number of parts.

Murray Corporation - Cockeysville MD

International Classification:

F25B 4500

US Classification:

62149

Abstract:

A mobile air-conditioner charging station having a reluctance-type weighing scale on which are mounted reservoirs of both lubricant oil and refrigerant. A computer module reads the weight loss of the combined reservoirs as, first, the oil is charged into the air-conditioner and then, sequentially and automatically, the refrigerant is charged into the air-conditioner. Each charging cycle is completed when the computer module senses, by a plurality of discrete readings of the scale at timed intervals, that a pre-selected magnitude of weight loss has occurred and has been maintained.
