Patent number: 7296573Abstract: A system including methods and apparatus for treatment of a medical disorder such as obstructive sleep apnea or congestive heart failure. The system involves applying a gain to flow rate of pressurized gas delivered to a patient during inspiratory and/or expiratory phases of a respiratory cycle to deliver the pressurized gas in proportion to the respective gains during inspiration and/or expiration. A base pressure may be applied in addition to the gain-modified pressures and an elevated pressure profile may be employed to assist or control inspiration. The system may be fully automated responsive to feedback provided by a flow sensor that determines the estimated patient flow rate. A leak computer can be included to instantaneously calculate gas leakage from the system. The system may be utilized in connection with conventional continuous positive airway pressure treatments, such as CPAP or bi-level positive airway pressure equipment to effect various beneficial treatment applications.Type: GrantFiled: July 15, 2005Date of Patent: November 20, 2007Assignee: RIC Investments, LLCInventors: Mark C.

Patent number: 7296585Abstract: A reduced component wear valve is comprised of a valve body having a passage therethrough and a disc attached to a rotatable shaft. The disc is utilized with a seal forming a gap between the disc and the seal proximate to the rotational axis of the disc. When the disc is in the open position, the seal major axis is greater then the disc diameter and they do not touch. As the disc rotates to near closure, the disc perimeter engages the minor axis of the seal (which is smaller than the disc diameter), and the disc stretches the seal in the minor axis direction thus decreasing the major axis such that the gap is closed. The seal can be pre-formed in an elliptical shape or it can be formed into an elliptical shape by a retaining mechanism. The seal may be a single-piece or a multi-piece assembly press-fit into the valve body. Zero or light disc to seal contact during the majority of the valve disc rotation minimizes valve seal wear and rotational friction.Type: GrantFiled: May 31, 2006Date of Patent: November 20, 2007Assignee: Fisher Controls International LLCInventors: Philip Wayne Eggleston, James Leroy Lounsberry, Wilbur Dean Hutchens

Patent number: 7296614Abstract: A method of controlling the formation of crocodile skin surface roughness on thin cast strip of plain carbon steel forming a casting pool of molten metal of plain carbon steel of less than 0.065% carbon supported on a casting surfaces above a nip, assembling a rotating brush to contact the casting surfaces in advance of contact with the molten metal, and controlling the energy exerted by rotating brushes against the casting surfaces of the casting rolls to clean and expose a majority of the projections of the casting surfaces of the casting rolls by provide wetting contact with the molten metal of the casting pool. The cleaning step may be done by controlling the energy of the rotating brush against the casting rolls based on the difference between the measured heat flux and the initially measured heat flux when the casting surfaces are clean, and automating the method.Type: GrantFiled: December 13, 2005Date of Patent: November 20, 2007Assignee: Nucor CorporationInventors: Mark Schlichting, Joel D.

Patent number: 7296615Abstract: A secondary datum scheme is used for identifying the location of the core-produced internal geometry of hollow investment cast metal parts that are made using a free-floating core design for implementing complex internal structural features. A set of datum pads are cast on a removable portion of the core print out to provide the secondary reference system. This secondary reference system precisely establishes the location of the core-produced internal geometry of the part exclusive of any fixed external primary datum structure/system so that, for example, precision machining and gauging may be performed upon such internal features during subsequent fabrication steps.Type: GrantFiled: May 6, 2004Date of Patent: November 20, 2007Assignee: General Electric CompanyInventors: Robert H. Devine, II, Gary M. Itzel

Patent number: 7296616Abstract: A shell mold for casting molten material to form an article is described. The mold includes a shell for containing the molten material, formed from at least one of yttrium silicates, zirconium silicates, hafnium silicates, and rare earth silicates. The mold also includes a facecoat disposed on an inner surface of the shell that contacts the molten material. The facecoat can be made from the materials described above. A method of casting a niobium-silicide article is also described, using the shell mold described herein. A method of making the ceramic shell mold is described as well, along with a slurry composition used in the manufacture of the shell mold.Type: GrantFiled: December 22, 2004Date of Patent: November 20, 2007Assignee: General Electric CompanyInventors: Bernard Patrick Bewlay, Laurent Cretegny, Michael Francis Xavier Gigliotti, Jr., Roger John Petterson, Ann Melinda Ritter, Stephen Francis Rutkowski

Patent number: 7296618Abstract: A liquid cooling system is disclosed for use in an electronic apparatus. The system is constructed to be of a reduced size and thickness, thus allowing it to be used for cooling heat-generating devices such as semiconductor elements, while maintaining corrosion resistance. The system includes a pump, a heat-receiving jacket, and flow passages through which the cooling liquid is circulated. An ion exchange bag having a water-permeable bag is disposed within the liquid cooling system. The water-permeable bag further contains an ion exchange resin therein.Type: GrantFiled: March 4, 2004Date of Patent: November 20, 2007Assignee: Hitachi, Ltd.Inventors: Rintaro Minamitani, Shinji Matsushita, Shigeo Ohashi, Yoshihiro Kondo, Takashi Naganawa, Osamu Suzuki
