Patent number: 6932106Abstract: A hose reel includes a base with two side panels and a mandrel is rotatably connected between the two side panels. Two side boards are connected to two ends of the mandrel and one of which is connected to a handle and the other side board receives a first end of a connection tube. The connection tube has hooks so as to be engaged with extensions at the opening of the side panel. By this way, the connection tube is secured to the side panel without adhesive. A cap with curve and smooth outside is mounted to a second end of the connection tube.Type: GrantFiled: November 19, 2004Date of Patent: August 23, 2005Inventor: King-Yuan Wang

Patent number: 6901955Abstract: The cryogenic rotary coupling comprises segments of a cryogenic line that are capable of turning relative to each other about a pivot axis of the rotary coupling. Radial retaining elements and axial retaining elements define the pivot axis of the rotary coupling. One of the segments comprises a vacuum-insulated double-walled female portion and the other segment comprises a vacuum-insulated double-walled male portion engaged at least in part in the female portion. A first sealing gasket is interposed between a free end of the male portion engaged in the female portion and one of the retaining means. A second sealing gasket is interposed between a free end of the female portion surrounding the male portion and the other one of the retaining elements. A heater device is disposed in the vicinity of the second gasket.Type: GrantFiled: July 11, 2003Date of Patent: June 7, 2005Assignee: SNECMA MoteursInventor: Dominique Valentian

Patent number: 6792966Abstract: A fuel transfer apparatus for providing fuel to a vehicle engine from a plurality of fuel tanks. A transfer pump is positioned intermediate a pair of fuel tanks and is operable to transfer fuel therebetween. Fuel is provided to the engine from a first one of the two fuel tanks. Excess fuel is returned to the first one of the two fuel tanks. When the level in the first fuel tank is less than the level in the second fuel tank by a predetermined amount, the transfer pump transfers an amount of fuel from the second fuel tank to the first fuel tank. Fuel level sensors are utilized to monitor the level of fuel in the two fuel tanks and report to a microprocessor which controls the transfer pump. The microprocessor utilized to control the transfer pump may be incorporated into the transfer pump, may be a stand alone microprocessor, or may comprise an existing vehicle circuit board such as, e.g., the electronic control module (ECM). A fuel transfer line interconnects the two tanks and is located above the two tanks.Type: GrantFiled: October 18, 2002Date of Patent: September 21, 2004Assignee: Federal-Mogul World Wide, Inc.Inventor: Richard W. Harvey

Patent number: 6766821Abstract: A reel for storing an air hose includes a hollow housing having a spring biased pulley rotatably mounted therein. A pressured air inlet extends through the housing along the pulley axis of rotation and is sealed to a nozzle rotating with the pulley. The pulley stores an air hose having one end connected to the nozzle and an opposite end extending through an opening in the housing for attachment to a pneumatic tool.Type: GrantFiled: February 24, 2003Date of Patent: July 27, 2004Assignee: Alert Stamping & Mfg. Co, IncInventors: James D. Kovacik, Paul S. Blanch, Joseph J. Smith

Patent number: 6668859Abstract: A collet assembly includes a collet and a tubular valve sleeve sleeved on a rotary shaft that is disposed within a stationary wall body and which defines a piston-receiving chamber. A piston is disposed movably in the piston-receiving chamber. The valve sleeve is formed with a valve opening therein, a valve chamber extending from the valve opening, a valve inlet in fluid communication with the valve chamber and a fluid injection passage in the stationary wall body, and a valve outlet in fluid communication with the valve chamber and a fluid channel in the shaft. A check valve is mounted in the valve chamber, and is moved to an open position, in which, the valve opening is opened due to injection of a high-pressure hydraulic oil into a clearance through the fluid injection passage, thereby permitting movement of the piston, which, in turn, results in clamping of the collet.Type: GrantFiled: October 21, 2002Date of Patent: December 30, 2003Inventor: Hsuan-Lung Wu

Patent number: 6648000Abstract: A spool for carrying continuous pipe or coiled tubing for a coiled tubing injector is dropped into a stand at a site and coupled to a rotary power source. The stand includes two axles, on either side of the spool, and a drive coupling. A pipe slideably extends through one of the axles. It is retracted when the spool is lowered onto the stand and then extended for communicating fluid between the coiled tubing and a fluid source. A swivel joint is connected to one end of the pipe. The pipe is permitted to turn with the spool or is held stationary with respect to the stand depending on whether the swivel joint is mounted outside the stand or inside the spool.Type: GrantFiled: November 9, 2001Date of Patent: November 18, 2003Assignee: Varco I/P, Inc.Inventors: Troy D. Cain, Timothy Scott Steffenhagen

Patent number: 6637454Abstract: A fluid handling system is disclosed having a swivel for connecting a stationary fluid source line to a fluid service line that is wound upon a reel. A rotor cap secures the fluid source line and a rotor within the swivel in position, allowing a housing within the swivel to freely rotate with the fluid service line and reel. The swivel is coupled to the fluid source line using a crimping ferrule to eliminate the necessity of predisposing mating components on the fluid source line. The swivel is further provided with seals that reduce the incidence of bunching and tear due to the reduction in drag imposed on the seals.Type: GrantFiled: May 31, 2002Date of Patent: October 28, 2003Inventor: Craig D. Eley

Patent number: 6622676Abstract: A cylindrical element having a first axis and at least one internal longitudinal passage, and a circular circumferential groove formed in an outer surface of the element and having a second axis. The groove eccentric of the element such that the groove intersects the wall of the longitudinal passage, forming thereby a rectangular opening therebetween. When a second longitudinal passage is present, it is similarly intersected by a second eccentric groove spaced apart axially from the first groove. The axis of the second groove is rotationally displaced about the element axis from the first groove, preferably by a large angle, for example 180°, such that the first eccentric groove does not intersect the second passage, nor does the second eccentric groove intersect the first passage.Type: GrantFiled: November 27, 2002Date of Patent: September 23, 2003Assignee: Delphi Technologies, Inc.Inventors: Ronald J.
