Patent number: 7246504Abstract: A method of manufacturing cooling storage units and a sales management system is to be provided for the same permitting the exclusion of a made-to-order production system which indispensably requires pre-shipment cooling tests. Thermally insulated boxes of different predetermined sets of specifications, each usable as a freezer, a refrigerator, or a freezer-refrigerator, and cooling units so fabricated as to have a prescribed cooling capacity for any one of the group of thermally insulated boxes are made ready in advance. One thermally insulated box, meeting the specified requirements from the group of thermally insulated boxes, and a matching cooling unit are transported to the installation site of the cooling storage unit. The thermally insulated box and the cooling unit are combined at the installation site to constitute the cooling storage unit.Type: GrantFiled: November 2, 2004Date of Patent: July 24, 2007Assignee: Hoshizaki Denki Co., Ltd.Inventors: Akihiko Hirano, Shinichi Kaga

Patent number: 7246505Abstract: A personal air conditioning system that may be used, for example, to cool a tent. The personal air conditioning system includes a cooling lid that fits over a typical insulated cooler. The cooling lid includes a heat transfer tower that is configured to transfer heat from a cold medium, such as ice, that is located within the cooler to an area within the cooling lid. A heat sink is provided at the top of the heat transfer tower and at least partially within the cooling lid. A fan is configured to draw air into the cooling lid, across the heat sink, and out of the cooling lid. The cooled air may then be used for cooling of a tent or other compartment, for example, or may be directed to blow on an individual.Type: GrantFiled: January 14, 2004Date of Patent: July 24, 2007Assignee: The Coleman Company, Inc.Inventors: Jose Enrique Navedo, James Michael Boenig

Patent number: 7246507Abstract: Provided is an air conditioner which has a separator with an oil tank for storing extra oil; a first oil return tube opening above the surface of the extra oil; and a second oil return tube opening below the surface of the extra oil. When the refrigeration cycle cannot maintain the required oil dilution ratio as a result of the refrigerant having been replenished to cope with long piping, extra oil can be supplied from the second oil return tube to maintain the required oil dilution ratio in the refrigeration cycle, while using a highly versatile general compressor.Type: GrantFiled: June 29, 2005Date of Patent: July 24, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshihito Yamada, Hideyuki Kanzaki

Patent number: 7246509Abstract: A knitted glove made by creating each of the sections of the glove using a separate knitting course on a flat knitting machine providing variable stitch dimensions. Each of these sections provides its own designed stretch characteristics so that the glove fits tightly, yet provides flexibility and ease of movement. The variable stitch dimension is achieved by 1) varying the depth of penetration of a knitting needle into a fabric being knitted by a computer program, 2) adjusting the tension of yarn between a pinch roller and a knitting head by a mechanism controlled by a computer, and 3) casting off or picking up additional stitches in a course. The glove includes a plurality of finger components made from at least ten separately knitted sections, two palm components, each of which is made from at least two separately knitted sections, and a wrist component made from at least one knitted section.Type: GrantFiled: December 19, 2006Date of Patent: July 24, 2007Assignee: Ansell Healthcare Products LLCInventors: Fred Hardee, Greg Plemmons, Eric Thompson, San Allen, Dave Narasimhan

Patent number: 7246512Abstract: A method for determination of the zero error of a Coriolis gyro. Appropriate disturbance forces are applied to the resonator of the Coriolis gyro such that at least one natural oscillation of the resonator is stimulated that differs from the stimulating and read oscillations. A change in a read signal which represents the read oscillation and results from the stimulation of the at least one natural oscillation is determined as a measure of the zero error.Type: GrantFiled: March 26, 2004Date of Patent: July 24, 2007Assignee: LITEF GmbHInventor: Werner Schroeder
