Abstract: An apparatus, system and method for servicing a coolant system, such as, an automobile air conditioner are disclosed. In one embodiment, the apparatus may comprise a device for measuring a parameter of the coolant system; and means for selectively switching between providing: (i) communication between the coolant system and said measuring device, and (ii) communication between the coolant system and the coolant supply.

Abstract: A touch activated illuminated hand rail assembly includes a hand rail in the form of an elongated opaque rigid hollow member having a construction of an outer plastic dielectric layer and an inner metallized layer so that the member functions as a capacitor which discharges electrical charge when touched by a person, a light bulb, such as an elongated fluorescent tube, disposed within the hollow member, a pair of conductor wires which connect to an external alternating current power source to provide electricity to the light bulb, an elongated cutout formed in the hollow member through which light emitted by the light bulb may shine outward to illuminate the area where the hand rail is installed, a timer device which turns on the light bulb when electrical charge is discharged from the hollow member and turns off the light bulb after passage of a fixed period of time, and a plurality of mounting brackets which attach the hollow member to a wall or other surface where a person may grasp it for support.

Abstract: A refrigerator is provided with a refrigerating unit in the form of an apparatus having at least one pair of containers, where each pair includes a first and a second container (18 and 20, respectively) communicating with each other through a pipe (22). Each container contains a substance which, when being heated, gives off a gaseous working medium and, when being cooled, absorbs the gaseous working medium. The first container (18) is arranged to be heated from the storage compartment (16) of the refrigerator, which compartment thereby is cooled. The second container (20) is provided with a heater (34). Each container is provided with an arrangement for, when need arises, conducting heat away from the respective container, which arrangement includes a cooling circuit (26, 28, 30, 32 and 36, 38, 30, 32, respectively), in which a pump (26, 36) brings a cooling liquid to cool the respective container. The liquid is cooled in a radiator (32) arranged on the refrigerator.

Abstract: A dual-adsorber cooling system for an automobile has a pair of adsorbers, a cooling vessel, a pair of absorbate outgoing passages extending from the cooling vessel to each of the adsorbers individually, a common adsorbate return passage, a condenser, and a condensation passage. A bypass passage enables the two adsorbers to directly communicate each other to exchange heat. The adsorbers are opposingly disposed with an intervening plenum therebetween. The engine exhaust gas is introduced to the central plenum, and the external air is guided to the central plenum through the adsorbing adsorber so that a blend of the exhaust gas and the air is directed to the desorbing adsorber in the plenum, whereby the adsorbing adsorber is cooled and the desorbing adsorber is heated up. The amount of the external air taken can be controlled according to the amount of the exhaust gas. A process switchover controller can adjust the process cycle period according to the temperature of the exhaust gas.
