Also included is a tubular inner sleeve concentrically disposed within the outer sleeve and having a plurality of inner sleeve circumferential grooves formed on an inner sleeve inner surface. A plurality of inner sleeve axial grooves are formed on the inner sleeve outer surface and intersect the inner sleeve circumferential grooves to form inner sleeve orifices. The offset inner and outer sleeve orifices define tortuous flow paths wherein fluid flows into the outer sleeve axial grooves, through the outer sleeve orifices, through the outer sleeve circumferential grooves, through the inner sleeve axial grooves, through the inner sleeve orifices before exiting the inner sleeve circumferential grooves.Type: ApplicationFiled: July 21, 2003Publication date: March 11, 2004Inventor: Harald Beth

Publication number: 20040045613Abstract: A diverter valve is disclosed that includes a cylindrical body having a bottom and lid and a plurality of body openings. A closure member is included within the cylindrical body that is movable to block one of the housing holes. A handle is connected to the closure member, with the handle being external to the cylindrical body. The turning of the handle causes the closure member to move within the body. The handle has a first set of vertical teeth and a spline on the lid has a second set of vertical teeth. The first and second sets of vertical teeth engage to lock the handle in place and disengage to allow the handle to turn. A plurality of label tags can also be included, at least one of which is mounted to the diverter adjacent to one of the body openings to indicate the source or destination of fluid flowing through said openings.Type: ApplicationFiled: September 6, 2002Publication date: March 11, 2004Applicant: WATERWAY PLASTICS, INC.Inventors: Francisco Hinojosa, Ruben Lerma, Steven Kramer

Publication number: 20040045614Abstract: A hydraulic interface plate is a generally flat plate that defines an upper surface and a lower surface. An upper fluid routing channel is formed in the upper surface of the interface plate. Moreover, a lower fluid routing channel is formed in the lower surface of the interface plate. A fluid interface port connects the upper fluid routing channel to the lower fluid routing channel. The upper fluid routing channel is configured to communicate with a solenoid fluid port established by a solenoid assembly module. Also, the lower fluid routing channel is configured to communicate with a transmission fluid channel established by a vehicle transmission.Type: ApplicationFiled: September 10, 2002Publication date: March 11, 2004Inventors: Viswanathan Subramanian, Luis F.

Publication number: 20040045615Abstract: The invention relates to a hydropneumatic pressure reservoir (1) with a housing formed from at least two housing shells (3, 5) which may be connected together. At least the end region of the one housing shell (5) comprises an outwardly-extending, funnel-like guide surface between the free end thereof and a sealing element for bringing together the two housing shells (3, 5). At least one elastic sealing element (41) is provided on at least one retaining surface for generation of a tensioning force on the boundary region (21) of the membrane (13). A simplified construction with improved sealing in the critical connection region of the pressure reservoir may thus be achieved.Type: ApplicationFiled: June 30, 2003Publication date: March 11, 2004Inventors: Gernot Rupp, Markus Lehnert, Herbert Baltes

Publication number: 20040045616Abstract: A wellbore casing formed by extruding a tubular liner off of a mandrel. The tubular liner and mandrel are positioned within a new section of a wellbore with the tubular liner in an overlapping relationship with an existing casing. A hardenable fluidic material is injected into the new section of the wellbore below the level of the mandrel and into the annular region between the tubular liner and the new section of the wellbore. The inner and outer regions of the tubular liner are then fluidicly isolated. A non hardenable fluidic material is then injected into a portion of an interior region of the tubular liner to pressurize the portion of the interior region of the tubular liner below the mandrel. The tubular liner is then extruded off of the mandrel.Type: ApplicationFiled: April 18, 2003Publication date: March 11, 2004Applicant: Shell Oil Co.Inventors: Robert Lance Cook, David Paul Brisco, R.

Publication number: 20040045617Abstract: A pipe liner bag everting nozzle is provided for allowing an operator to freely access a manhole during a lining operation. A pipe liner bag everting nozzle comprises a guide tube fixing end for fixing one end of a guide tube, and a pipe liner bag fixing end for fixing a folded end of an uneverted pipe liner bag passed through the guide tube, wherein the guide tube fixing end has a diameter smaller than a diameter of the pipe liner bag fixing end. Since a guide tube having a smaller diameter than that of a pipe line to be repaired (or the pipe liner bag) can be used, a sufficient gap is formed between the guide tube and the manhole, thereby allowing the operator to freely access the manhole during the lining operation for inspection and confirmation of a lining situation.Type: ApplicationFiled: September 9, 2003Publication date: March 11, 2004Inventors: Takao Kamiyama, Yasuhiro Yokoshima, Shigeru Endoh, Hiroyuki Aoki

Publication number: 20040045618Abstract: Insulated electrical conductors for installation in a vehicle, such as an aircraft, are further protected by a guard hose or tubular member. Two or more such guard hoses or tubular members are interconnected with each other by at least one spacer preferably, but not necessarily, integrally formed with the guard hoses or tubular member, whereby the separation of different types of electrical conductors and their installation in an aircraft are facilitated.Type: ApplicationFiled: September 8, 2003Publication date: March 11, 2004Inventor: Klaus-Hinrich Borchers

Publication number: 20040045619Abstract: A multilayer PEX pipe having improved resistance to oxidizing agents in water. The pipe has a thin tubular core (inner layer) of high density polyethylene and an outer layer of crosslinked polyethylene. The pipe may optionally have an oxygen barrier layer, such as poly(ethylene-co-vinyl alcohol) (“EVOH”), contiguously disposed radially outward from the PEX layer. The pipe is suitable for potable water applications and for hot water radiant heating systems.Type: ApplicationFiled: July 10, 2003Publication date: March 11, 2004Inventors: Arthur L. Backman, Girish T. Dalal, Carl M. Mahabir

Publication number: 20040045620Abstract: Polyamide liners used in sub sea and over ground transport operations, such as nylon (11), are handled in a way which increases the rate of chain recombination relative to the competing process of chain scission. This enhances and increased the useable life of the polyamide liner by effectively reducing its rate of aging. The can be accomplished by incorporating a chain extender or desiccant into the polyamide liner, incorporating hydrophobic moieties or hydrophobic polymers into the polyamide liner, or by providing a sheath which is less permeable to water at the inner surface of the polyamide liner. Rejuvenation of the polyamide liner can also be achieved by heat treatment of the polyamide liner by hot air, hot oil or gas, or other hot liquids that are at a temperature above 1000° C. Rejuvenation may be enhanced by including a chain extender or desiccant to a hot oil, gas, or other liquid that is exposed to the polyamide liner.Type: ApplicationFiled: October 16, 2003Publication date: March 11, 2004Inventor: David E.
