Publication number: 20050284621Abstract: A refrigerant evaporator includes an upstream tank portion for distributing refrigerant into all laminated tubes of a core portion. The upstream tank portion includes a first distribution passage for distributing the refrigerant into the tubes in a direction parallel to a tank longitudinal direction, a second distribution passage for distributing the refrigerant from the first distribution passage into the tubes in a tank width direction, and a communication passage through which the refrigerant from the first distribution passage is supplied to the second distribution passage after flowing in the tank longitudinal direction. Therefore, refrigerant can be uniformly introduced into all the tubes.Type: ApplicationFiled: June 23, 2005Publication date: December 29, 2005Applicant: DENSO CorporationInventors: Yoshiki Katoh, Masaaki Kawakubo, Etsuo Hasegawa

Publication number: 20050284622Abstract: Flow is managed within a fluid delivery system such as an HVAC system. In one illustrative embodiment, a method is provided for controlling the airflow and thus the heat delivery rate to a room serviced by an HVAC system. The HVAC system includes a duct system that is in fluid communication with a room through a damper or the like. Other embodiments are also disclosed.Type: ApplicationFiled: June 28, 2004Publication date: December 29, 2005Inventor: Steven Nichols

Publication number: 20050284623Abstract: A combined muffler and heat exchanger apparatus is provided. The apparatus includes a housing defining a heat transfer chamber and an acoustic attenuation chamber separated by a partition. A flow regulator and a fluid transport member are disposed within the heat transfer chamber. The flow regulator is adapted to regulate the flow of a first fluid, such as a heat source, between an input end of the housing and the partition. The fluid transport member is adapted to contain the flow of a second fluid. An acoustic regulator is disposed in the acoustic attenuation chamber and extends longitudinally from the partition to an output end of the housing. The acoustic regulator is a metal tube including a plurality of apertures adapted to attenuate exhaust stream acoustics associated with an automotive vehicle power source.Type: ApplicationFiled: June 24, 2004Publication date: December 29, 2005Inventors: Wallace Poole, James Abbott, Gabriel Kuschel, Jian Hua

Publication number: 20050284624Abstract: An insert having a plurality of ports creating angled passageways through the walls of the insert is positioned in a drill string for altering fluid flow in the drill string and inducing vibration sufficient to speed up directional drilling and to prevent differential sticking in wellbores. Boundary layer flow along the walls of the drill string is drawn into an upstream group of ports to commingle with fluid in the central bore of the drill string and the insert. The flow is separated at a downstream group of ports and angled passageways cause the flow to be directed radially outward inducing vibration into the drill string.Type: ApplicationFiled: June 23, 2005Publication date: December 29, 2005Applicant: VIBRATECH DRILLING SERVICES LTD.Inventors: Kelly LIBBY, Dave TROTTER

Publication number: 20050284626Abstract: A pulsed neutron source irradiates an earth formation. The irradiation produces N16 from O16 in a fluid in the borehole, and the gamma rays produced by the subsequent decay of N16 are detected by a plurality of spaced apart detectors. The count rates of the detectors are accumulated over a time sampling interval to produce temporal signals. Processing of the temporal signals using correlation, differentiation and/or semblance techniques is used for determination of the flow velocity of one or more fluids in the borehole.Type: ApplicationFiled: June 29, 2004Publication date: December 29, 2005Inventors: Stephen Riley, Benoit Guivarch, Darryl Trcka, David Chace

Publication number: 20050284628Abstract: The present invention is a method and system for dissociating methane hydrate deposits in-situ. An oxidizer fluid and a supply of fuel, both at a pressure higher than that of the methane hydrate deposit, are supplied and delivered to the methane hydrate deposit. The fuel is combusted downhole by reacting it with the oxidizer fluid to provide combustion products. The combustion products are placed in contact with a diluent fluid to produce a heated product fluid. The heated product fluid is injected into the methane hydrate deposit whereby methane is dissociated from the methane hydrate and made available for extraction. In addition, carbon dioxide may be made available to promote the formation of carbon dioxide hydrates from the liberated methane hydrate water.Type: ApplicationFiled: August 30, 2005Publication date: December 29, 2005Inventor: William Pfefferle
