| 20100243200 | SUCTION LINE HEAT EXCHANGER MODULE AND METHOD OF OPERATING THE SAME - A heat exchanger module configured for use in a vapor compression based climate control system including a suction line heat exchanger having a plurality of stacked plates configured to accommodate two separate fluid flow paths for heat exchange therebetween. The heat exchanger also includes a first inlet for flow of a high pressure subcooled fluid from a condenser to the module along a first fluid flow path, a first outlet for flow of a low pressure superheated fluid from the module to a compressor along a second fluid flow path, a second outlet for flow of the subcooled fluid from the module to an evaporator along a third fluid flow path, and a second inlet for flow of the low pressure superheated fluid from the evaporator to the module along a fourth fluid flow path. The module also includes a port block with a first conduit for the third fluid flow path and a second conduit for the fourth fluid flow path. | 09-30-2010 |
| 20110067837 | HEAT EXCHANGER - A heat exchanger includes a bundle of tubes, which can be inserted into a tubular housing. Exhaust gas can flow through the tubes. A coolant duct can be arranged between the tubes. The bundle of tubes can have at least one grid-like securing structure which supports the bundle in the housing. The behavior of the heat exchanger with respect to vibrations is affected by outwardly curved metallic springs attached to the bundle of tubes which may be deformed in the opposite direction to the insertion direction of the bundle into the housing. The spring force is directed against the housing in order to dampen vibrations. The heat exchanger can also include an elastic device for permitting a change in length caused by temperature changes. | 03-24-2011 |
| 20110186276 | HEAT EXCHANGER ASSEMBLY AND METHOD - A heat exchanger is described and illustrated, and in some embodiments includes a casing, a fluid flow path extending between first and second ends of the casing; first and second bundles of heat exchanger tubes in first and second portions of a fluid flow path extending through the casing, and a third section of the fluid flow path connecting the first and second sections and having a sealing plate with one or more apertures for the fluid flow path to pass therethrough. In some embodiments, by virtue of the sealing plate and its relationship with the adjacent structure of the heat exchanger, adjacent ends of the two bundles of tubes are each movable in at least one direction with respect to the casing and the other bundle of tubes. | 08-04-2011 |

| 20090106906 | SELF-CONTAINED GATCHING, ROTATING AND ADJUSTABLE FOOT SECTION MATTRESS - A self-contained gatching mattress having a gatching mattress sleep deck, a first air bladder cushion, a second cushion material, a control box having an air pump system and a manifold, a conduit distribution unit, a sliding bridge, and a cushion material positioned above the sliding bridge and the control box. The sliding bridge forms a gap area for conduits to extend from the control box to the conduit distribution unit which decreases the chances of the conduits being kinked or altering the cushion's tissue interface pressure to patient's positioned on the cushion when the sleep deck is gatched and/or portions are retracted or extended. | 04-30-2009 |
| 20090112298 | HIGH EFFICIENCY THERMAL ENERGY TRANSFER PAD - A thermal energy transfer pad is disclosed. The thermal energy transfer pad has a first flexible, thermal energy transfer sheet and a second flexible, thermal energy transfer sheet. The first flexible, thermal energy transfer sheet (a) is made of a first fluid impervious material, (b) has a perimeter measurement of A prior to manufacturing and (c) has a first thermal energy transfer thickness. The first flexible, thermal energy transfer sheet is molded to form fluid path troughs defined by interior protuberances and the first sheet's perimeter edge. That molding alters the first flexible, thermal energy transfer sheet's perimeter measurement to B, which is less than A. The second thermal energy transfer sheet (a) is made of a second fluid impervious material, (b) has a perimeter measurement of B and (c) has a second thermal energy transfer thickness. The second thermal energy transfer sheet is sealed to the first thermal energy transfer sheet along the first sheet's perimeter and at the first sheet's interior protuberances. That sealing creates a tortuous fluid path in the fluid path troughs The resulting pad has a significantly (1) decreased chance of the fluid being occluded in the fluid path and (2) increased thermal energy transfer rate to the patient. | 04-30-2009 |
| 20090246449 | GELASTIC MATERIAL HAVING VARIABLE OR SAME HARDNESS AND BALANCED, INDEPENDENT BUCKLING IN A MATTRESS SYSTEM - A cushioning element has a first gelastic cushion element made from a flexible, resilient, gel cushioning media having shape memory. The first gelastic cushion element has a first hub section, and a first spoke and a second spoke. Each spoke has a proximal end that extends from the first hub section. Each distal end and the spoke area between the distal end and the proximal end does not interconnect to the other spoke, and/or a second gelastic cushion element having a second hub section and corresponding spokes. Each distal end is positioned near and/or contacts the second gelastic cushion element. At least one of the first hub section, the first spoke and the second spoke is capable of buckling beneath a protuberance that is located on the object. | 10-01-2009 |
| 20100199437 | MULTI-WALLED GELASTIC MATERIAL - The present invention is directed to a gelastic cushion. The gelastic cushion is made from a conventional gelastic composition. The gelastic cushion has a structure having a first wall that defines an opening area and buckles when a force is applied to the first wall. When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable. | 08-12-2010 |

When the first wall buckles a predetermined amount, a second wall, interconnected to the first wall, also buckles. The second wall decreases the chance that the first wall bottoms out. Bottoming out increases the pressure on the patient (a.k.a., the force) overlying the gelastic cushion. That increased pressure is undesirable. | 08-19-2010 |
