Abstract: A golf cart cooling apparatus for cooling golfers seated in a golf cart. The cooling apparatus includes a reservoir for holding a liquid such as water. A pump is provided for pumping the liquid out of the reservoir. The pump is in liquid communication with the reservoir by a tube or by being mounted on the reservoir. A conduit assembly is provided for spraying the liquid from the reservoir to a position generally adjacent to the golfers in the cart. Activation of the pump diffuses a mist of the liquid over the golfers.

Abstract: An air filter system for refrigerators includes an economically and easily manufactured housing having a replaceable air filter supported within the housing, and a releasable connector associated with the housing permits the housing of the air filter system to be readily and easily removed from the refrigerator, to permit the easy replacement of the air filter.

Abstract: A dispener comprising a liquid supply and a cooling reservoir, the cooling reservoir having an entry port and an exit port. The cooling reservoir is shaped so as to position a pocket of air at the top of the reservoir when the reservoir contains liquid, and the entry port communicates with the air pocket. The dispenser has a conduit connected on one end to the liquid supply and on the other end to the entry port of the cooling reservoir. The dispenser further comprises a cooling element disposed inside the cooling reservoir and a first pump for moving the liquid from the liquid supply to the cooling reservoir through the conduit.

Abstract: A filter/drier has, in one embodiment, an expansion valve block formed integrally with a header welded to a desiccant-containing canister. The block has a bore into which is received a precalibrated thermally responsive cartridge valve after the welding operations to prevent exposure of the cartridge valve to the elevated temperatures experienced during welding. In another embodiment, a valve block has one end of a first conduit welded to the high pressure inlet port and one end of a second conduit welded to the low pressure discharge port. A cartridge type thermally responsive precalibrated expansion valve is assembled in a block bore after welding is completed to prevent the expansion valve from being exposed to elevate temperatures experienced during welding.

Abstract: An air conditioning unit comprising: a housing having a first half and a second half; the first half of the housing containing an indoor heat exchange coil and a blower moving air through said coil from at least a housing inlet to a housing outlet. The blower discharges into a diffuser duct having a diffuser section with a first segment and a second segment where the first and second segments have first and second respective and differing angles of diffusion.

Abstract: An adsorbent unit including a porous container having first and second end portions, adsorbent in the container, a rigid clip on the first end portion for engaging the spaced pipes of a U-bend of a refrigerant accumulator, a tab on the second end portion, and an aperture in the tab for receiving the filter housing on the return bend of a U-shaped pipe.

Abstract: A housing for protecting monitoring equipment employed to maintain watch over dusty environments. The housing comprises a cylindrical jacket (1) that accommodates the equipment. The front of the jacket is closed except for one or more apertures (12) and extends into the environment being monitored. The housing is provided with a connection (10) for a coolant or flush in the form of air. One or more outlets (15 & 17) communicate with the inside of the housing in the vicinity of the aperture and are oriented such that the air emerging from the outlets forms a cushion between the aperture and the environment being monitored.

Abstract: A refrigerating apparatus improves the insulating effect of a refrigerating chamber which is maintained at ultra low temperatures by a twin refrigerating apparatus. A vertical ultra low-temperature freezer 1 is composed of an insulating frame with a composite structure of a vacuum insulating panel and a foam insulating material, an insulating door with a composite structure of vacuum insulating panels and a foam insulating material, and a twin refrigerating apparatus which cools goods stored in the insulating frame. Ultra low temperatures are produced by the twin refrigerating apparatus in which a high-temperature side refrigerant circuit and a low-temperature side refrigerant circuit are in cascade connection.
