Publication number: 20030131844Abstract: Devices and methods to heat and cool human beings, including inducing and maintaining hypothermia in human patients. Methods include inducing hypothermia to treat ischemic events, including heart attack and stroke, to limit damage caused by the ischemic event. Methods can include: using the lungs for heat exchange; using cooled gases for ventilation; using helium in the ventilation gas mixture, using medications to control reflex heat production; and injecting a perfluorocarbon mist into the gas stream to increase the cooling rate. The high thermal conductivity and diffusivity of helium results in greater inspired gas temperature equalization toward body temperature. Due to the latent heat of vaporization, addition of even small quantity of phase-change perfluorocarbon dramatically increases the heat carrying capacity of the respiratory gases. Hypothermia may be terminated by discontinuing the medications and warming the patient using a warmed helium-oxygen mixture.Type: ApplicationFiled: December 4, 2002Publication date: July 17, 2003Inventors: Matthew M.

Publication number: 20030131846Abstract: Improved full-face, flushed-seal respirators are provided having a primary sealing element adjacent to a breathing space and a secondary sealing element. Exhaled air (i.e., clean air obtained by passage through a filtering element or elements) is passed from the breathing space into a flushing channel formed between the primary and secondary seals. If there is leakage in the primary seal, air from this flushing channel leaks into the breathing space rather than ambient air. Air within the flushing channel will predominately be air that has already passed through the filtering elements. The present invention provides, therefore, an inexpensive respirator which provides significantly more protection than conventional negative-pressure respirators.Type: ApplicationFiled: December 10, 2002Publication date: July 17, 2003Inventors: Donald L.

Publication number: 20030131888Abstract: A refueling system for vehicles including a dual valve receiver connected in fluid communication with the fuel tank, and a jet sensor inside of the fuel tank and in fluid communication with the receiver. The refueling system further includes a relief valve vent in fluid communication with the fuel tank to vent the fuel tank and to relieve pressure that may otherwise build up inside the fuel tank during refueling. When refueling with an automatic shutoff nozzle, the sensor detects when a desired fuel level has been reached, and then informs the receiver to prevent fuel flow into the tank. When this occurs, the pressure inside the receiver and automatic shutoff nozzle increases, causing the nozzle to shut off automatically.Type: ApplicationFiled: January 15, 2002Publication date: July 17, 2003Inventors: Jose Cortez, David Wicke

Publication number: 20030131889Abstract: The present invention relates to a pilot poppet type pressure control valve capable of discharging a part of a fluid for thereby constantly maintaining a pressure of a high pressure chamber when the pressure of the high pressure chamber exceeds a certain level. In the pilot poppet type pressure control valve according to the present invention, a discharging port capable of discharging a fluid of a high pressure chamber includes an inner diameter which is gradually increased in a downstream direction for preventing an instant pressure decrease based on the opening by a pilot poppet when the pressure of a high pressure chamber exceeds a certain level. Therefore, in the present invention, it is possible to decrease a vibration and noise based on the discharge of a high pressure fluid based on the inventive construction of the discharging port. In addition, it is possible to process the discharging port at one time using a programmed NC lathe.Type: ApplicationFiled: January 11, 2002Publication date: July 17, 2003Inventor: Jin Wook Kim

Publication number: 20030131890Abstract: The present invention is a self-acting valve, and it may specifically be used for air mattresses. This self-acting valve consists of a housing, a membrane and a base. After a quick inflation, the elastic airtight membrane positioned within the housing reverts to its original shape and instantly shuts off the outlets, which prevents air from leaking out. This valve is able to operate automatically to form a perfect airtight seal. The structure of this valve is simple, reliable, and practical, which makes it a new type of self-acting valve for an air mattress.Type: ApplicationFiled: June 26, 2002Publication date: July 17, 2003Inventor: Senyuan Xie

Publication number: 20030131891Abstract: The duct connector of the present invention preferably has a rectangular inlet and a round outlet. An intermediate passage is located between the rectangular inlet and the round outlet. Preferably, the intermediate passage provides a smooth transition that is substantially free from steps, sharp corners, breaks or facets, and acts to smoothly funnel airflow from the rectangular inlet to the round outlet. The intermediate passage preferably includes transitional surfaces that connect adjacent walls of the duct. Each transitional surface preferably provides a single smooth continuously curved surface connecting a side wall and an adjacent end wall along the intermediate passage. The smooth transition of the intermediate passage and the use of transitional surfaces as just described reduces turbulence and noise within the duct connector and results in greater fan or blower efficiency.Type: ApplicationFiled: January 11, 2002Publication date: July 17, 2003Inventors: Richard R. Sinur, Tom Heidel

Publication number: 20030131892Abstract: A non-return valve has a valve housing with a flow channel having a vertical channel section, an inlet aperture, an outlet aperture and a blocking device closing the flow channel. The blocking device comprises a valve seat surrounding the outlet aperture and a valve disc movable between an open position and a closed position. The valve disc is guided in the valve housing via a guide surface on its outer circumference, and comprises flow apertures radially outside its sealing surface. The valve disc possesses a diameter that becomes smaller towards the valve seat, forming an inclined external surface. Flow apertures start from the inclined external surface and converge in the direction facing away from the sealing surface, and are disposed in a uniform distribution over the circumference of the valve disc.Type: ApplicationFiled: December 13, 2002Publication date: July 17, 2003Inventor: Axel Hebmuller
