  • Patent number: 7201013
    Abstract: Disclosed is an air conditioning apparatus with two adsorption elements (81, 82). The air conditioning apparatus repeatedly alternately performs a first operation in which air is dehumidified by the first adsorption element (81) simultaneously with regeneration of the second adsorption element (82) and a second operation in which air is dehumidified by the second adsorption element (82) simultaneously with regeneration of the first adsorption element (81). At the time of switching between these operations, only the flow path of air is changed, with the adsorption elements (81, 82) remaining stationary. The air conditioning apparatus includes a refrigerant circuit. The refrigerant circuit performs a refrigeration cycle in which a regenerative heat exchanger (92) operates as a condenser and either one of first and second cooling heat exchangers (93, 94) operates as an evaporator.

  • Patent number: 7131276
    Abstract: The present invention relates to pulse tube refrigerators for recondensing cryogenic liquids. In particular, the present invention relates to the same for magnetic resonance imaging systems. In many cryogenic applications components, e.g. superconducting coils for magnetic resonance imaging (mri), superconducting transformers, generators, electronics, are cooled by keeping them in contact with a volume of liquified gases (e.g. helium, neon, nitrogen, argon, methane). In a first aspect, the present invention provides a pulse tube refrigerator PTR pulse tube refrigerator (PTR) arrangement within a cryogenic apparatus, wherein a regenerator tube of the PTR is finned. In this configuration the fins or baffles, are believed to increase the surface area available for distributed heat transfer from the helium atmosphere to the regenerator.

  • Patent number: 7100394
    Abstract: An adaptor enables a convective treatment system to be modified for cooling by providing a bath of pressurized, cooled air intended to lower the body core temperature of a person. The adaptor may be constructed for being coupled between a blower assembly that provides a stream of pressurized air and a convective treatment device that receives the stream of pressurized air, distributes it, and provides it for bathing the body of a person in a general bath of cooled air in order to produce a desired clinical effect such as prevention or alleviation of hyperthermia or for thermal comfort. Such an adaptor may be embodied as an enclosure having a shaped internal cavity. The shape is useful for effectively and efficiently distributing a flow of pressurized over, around and through a bed of ice disposed in the cavity. Ports are provided in the enclosure for introducing a flow of pressurized air into, and receiving a flow of pressurized air from, the cavity.

  • Patent number: 6990751
    Abstract: An air knife or air nozzle manifold for drying or blowing off passing articles moved by a conveyor system is provided with a coupling that permits rotation of the air knife or air nozzle manifold relative to the air inlet duct leading from a blower. The air knife or air nozzle manifold has opposing ends located equidistant from a longitudinal axis of rotation relative to a stationary element of the coupling. Thrust nozzles are provided at each of the opposing ends of the air knife or air nozzle manifold to deflect a certain portion of the air from the plenum chamber to provide thrusting jets of air that rotate the air knife or air nozzle manifold about the longitudinal axis. The flow of air emitted from the air knife or air nozzle manifold is thereby directed onto the passing articles from different directions as the articles move by. The efficiency of drying and blowing off the articles to be processed is thereby significantly improved.

  • Patent number: 6971186
    Abstract: A filter assembly for collecting lint in use with a dryer having an interior compartment. The filter assembly includes a control unit, an input air pathway in communication with the interior compartment, an exhaust, and a micro-filter. The input air pathway carries air and lint from the interior compartment through the micro-filter into the exhaust. The filter assembly includes a first and second air flow sensor in the interior compartment for determining the change of air flow between the input air pathway and exhaust. The control unit is in communication with the first and second air flow sensors and an alarm. The control unit triggers the alarm when the air flow sensors detect a restricted pattern of air flow, thereby signaling a build-up of lint in the filter.

  • Patent number: 6968703
    Abstract: The Mechanical Freezer of this invention closely approaches an ideal freezer cycle composed of constant temperature compression, expansion, and constant volume heating (load transfer) by using power piston 106 that power input shaft 50 moves up and down and displacers 104 and 105 that are moved by cam 108. When power piston 106 moving up and additional displacer 105 moving down come together, fluid is forced through additional heat sink 41 where it is cooled as it is compressed. When additional displacer 105 and primary displacer 104 come together, fluid is forced through primary heat sink 40 where it is cooled as it is compressed. After compression, the cooled fluid is expanded by power piston 106 along with displacers 104 and 105 moving down. When displacers 104 and 105 then move up, fluid is forced through load 30 and load 30 is cooled.

  • Patent number: 6968704
    Abstract: The present invention relates to methods and systems for densifying liquids, specifically the densification of cryogenic propellants. A preferred system of the present invention subcools and densifies liquid propellants by utilizing a countercurrent gas or liquid flow. The countercurrent flow preferably utilizes a gas having a lower boiling point than the propellants. A packed tower may then be used, at or above atmospheric pressure, to introduce the countercurrent flow to the propellant. This methodology avoids the costs and problems associated with subatmospheric operation. A preferred embodiment is directed toward the densification of liquid oxygen, with a similar embodiment directed toward the simultaneous densification of liquid oxygen and liquid hydrogen. Systems and methods of the present invention may also be used to densify other liquids in similar fashion.

  • Patent number: 6941677
    Abstract: A portable air heating system for use in remote areas is disclosed. The portable air heating system provides a stream heated air for use in heating the interior of a structure, such as a tent or camp trailer. The heating system generally comprises an air transfer assembly for providing a flow of air through the system, a fuel burner assembly for providing heat by combustion, and a heat transfer housing for safely transferring the heat produced by the fuel burner assembly to the air flowing through the transfer assembly. The burner assembly and the heat transfer housing are both positioned outside the area being heated. Further, the exhaust gases are completely isolated from the air heated by the system, thereby virtually eliminating the likelihood of asphyxiation by the exhaust gases from the burner. The present heating system is also highly portable and simple to use, thereby providing an efficient mechanism for providing heat where more traditional heating apparatus are not readily available.

  • Patent number: 6938358
    Abstract: A method, apparatus and article of manufacture for providing electromagnetic drying of printed media. A resonant cavity allows support of standing waves along many radial axes throughout the resonant cavity. The electromagnetic drying unit allows forced air to be introduced into the resonant cavity, thereby reducing moisture within the resonant cavity and extending the life of the resonant cavity. Input and output openings may be arranged longitudinally along the resonant cavity and may be designed to substantially reduce the amount of electromagnetic radiation emanating from them during operation. A honeycomb feature at the end of the resonant cavity may allow egress of the forced air, while substantially reducing the amount of electromagnetic radiation emanating from the end of the resonant cavity.
