  • Patent number: 5435152
    Abstract: An air treating device having a bellows box in which is mounted a bellows compressor formed of two spaced apart diaphragms having memory-shaped metal alloy elements embedded therein. The diaphragms are caused to contract and expand by selective heating of the memory-shaped metal alloy elements. The bellows compressor is supported spaced in the bellows box whereby air can flow through the box and as the bellows expand the air in the box is cooled and expelled. As the diaphragms of the bellows compressor contract, more air is sucked into the bellows box and at the same time the refrigerant fluid inside the bellows is expelled into a condenser where it is condensed to liquid. When the refrigerant liquid enters into the bellows it is vaporized and cools the bellows walls in their expanded state and the diaphragms act as a heat exchanger to cool air in said bellows box and expel it therefrom.

  • Patent number: 5435150
    Abstract: An apparatus for heating and/or cooling a cabin, especially a passenger compartment of a motor vehicle, a sleeping cabin of a truck, or the like. To the cabin there is respectively connected an intake-air duct and a waste-air duct. The apparatus includes a sorption reactor which is filled with zeolite, or the like, and through which an air-current flows via corresponding ducts. In the adsorption phase of the reactor, the air-current takes up adsorption heat and releases moisture. After being cooled down via a humidifier, the air-current cools the intake-air current to the cabin. In addition, a heating device is provided for heating up the air current for the desorption of the reactor, the heated air current being evacuated with the moisture taken up from the sorbent.

  • Patent number: 5435144
    Abstract: A compressor lubricant distributing system includes a suction outlet to an auxiliary compressor housing and a lubricant and refrigerant return conduit. The return conduit extends from the suction outlet associated with the auxiliary compressor to a suction inlet conduit leading to a suction inlet of a primary compressor. The suction outlet associated with the auxiliary compressor is positioned at a proper lubricant level in the auxiliary compressor housing. When the primary compressor is operated, the suction created at its suction inlet is applied to the suction outlet associated with the auxiliary compressor, this suction draws excess lubricant at the auxiliary compressor back to the primary compressor.

  • Patent number: 5428904
    Abstract: Moist sewage sludge is dried in a sludge dryer having several zones. The initial moisture content of the sewage sludge may range up to 80% by weight, while the dried bulk material shall have a remainder moisture content of about 5% by weight. The drying gas temperature is maintained at a level up to 50.degree. C. to avoid activating additives that may be present in the sludge in the form of harmful substances to avoid the entry of these substances into the atmosphere. Furthere, the escape of processing air that has a noxious odor is avoided by passing the air through a deodorizer. The drying gas itself is reconditioned by reducing its moisture in a separate gas drying circuit from which the dried gas is again returned as a drying gas into the sludge dryer. A gas drying agent, such as a hygroscopic material is used in the gas dryer and the gas drying agent itself is regenerated by withdrawing moisture therefrom in a regenerating circuit.

  • Patent number: 5427521
    Abstract: A valve flushing system supplies a cleaning gas to a relatively large plenum, which in turn communicates with a restricted passage directing the flow along a face of the valve disk. In a main feature of this invention, a flushing gas flow moves through a restricted path along a face of a valve disk away from a valve disk contact area with a valve seat. In this way, the flushing gas prevents a potential leakage gas flow from approaching the valve/valve seat interface. In this way, leakage is reduced. Although the efficiency of the system may be reduced by a small amount, the resulting prevention of leakage more than justifies this potential small decrease in efficiency. The use of the relatively large plenum ensures that there will be complete and adequate coverage of the valve disk preventing any leakage across the valve disk. In an important feature of this invention, supply passages extend into the plenum along a direction which does not include a component moving in the direction of the valve disk.

  • Patent number: 5426955
    Abstract: An absorption refrigeration system which has a method for separation an absorption enhancing additive from a composite refrigeration fluid. The system has a separator interposed in sites between an absorber and a generator to distill an additive from a composite refrigeration fluid. After the separator a composite refrigerant passes through a generator, a condenser and an evaporator before being passed to an absorber. The additive distillate is passed directly to the absorber from the separator bypassing the more volatile components of the system. The additive contacts the refrigerant fluid in the absorber thereby improving the absorption rate.

  • Patent number: 5426865
    Abstract: A vacuum creating method comprising preparing a chamber for forming a space which can be made so atmospheric and vacuous as to allow a substrate to be directly or indirectly carried in and out of the space, exhausting the chamber, filling the space in the chamber with a CO.sub.2 gas whose vapor pressure becomes larger than 1 atm at ambient temperature but smaller than 10 Torr at a temperature lower than the ambient temperature, carrying the substrate into the chamber, cooling the CO.sub.2 gas to solidify, thereby making an internal pressure in the chamber highly vacuous, carrying the substrate out of the chamber, and heating the solidified dry ice to vaporize thereby returning the internal pressure in the chamber to atmospheric pressure.

  • Patent number: 5423194
    Abstract: The instant invention is directed to a counter-top service bowl for chilling various foods and beverages. A miniaturized refrigeration system is secured to the outer surface of the bowl having an evaporator coil disposed within a coil chamber. Air is directed through the chamber and into the middle of the bowl cavity. At the bottom of the bowl is a series of holes lining the bottom of the bowl for induction back into the circulation chamber. In operation the bowl acts as a chiller wherein solid foods such as fruit is chilled by air circulation and associated contact along the surface of the bowl. A bowl liner insertable into the base bowl permits placement of non-solid foods such as fruit salads. The bowl liner seals the circulation chamber forcing air past an evaporator coil and outward through an exhaust port. The bowl liner can be removed for use as a conventional bowl and returned to maintain the chilled condition.
