Said piston separates a fluid side (15) of the accumulator from the gas side (23) thereof and comprises two sealing areas (17, 25) which are offset in relation to each other in the axial direction thereof, said sealing areas being arranged on the circumference thereof and being displaced on the inner wall of the accumulator housing. The invention is characterized in that the accumulator housing (1) is provided with a ventilation device (31) between said sealing areas (17, 25) for discharging leaking means passing through the sealing areas (17, 25).Type: ApplicationFiled: February 10, 2004Publication date: December 2, 2004Inventor: Norbert Weber

Publication number: 20040238055Abstract: Apparatus used for the transport of fluids, the apparatus being suitable for use in oil-well production pipelines and pipelines and pipelines connectors used in oil fields or other applications where fluid contains a solid or where a solid is readily precipitated from the fluid. The apparatus comprises a conduit provided with at least one circumferentially discontinuous profiled turbulence inducing means formed around an inner diameter surface of the conduit. The turbulence inducing means may be formed integrally with the inner diameter surface of the conduit. The invention creates turbulent flow thereby preventing the build up of blockages in the conduit which can occur if solid masses form in the conduit.Type: ApplicationFiled: July 14, 2004Publication date: December 2, 2004Inventor: Martin John Gardner Doig

Publication number: 20040238057Abstract: An insulated duct assembly includes an elongated duct, an insulation blanket, at least one sheet of escape wick material and a tape layer. The insulation blanket has an inner wicking layer. The insulation blanket is applied to the elongated duct so as to create a seam aligned longitudinally with respect to the duct. The seam is defined by first and second edges of the insulation blanket. The at least one sheet of escape wick material is disposed along at least one edge of the insulation blanket. The at least one sheet of escape wick material has a “C” shaped cross-section surrounding the at least one edge of the insulation blanket. The tape layer is disposed along and covers the seam.Type: ApplicationFiled: May 30, 2003Publication date: December 2, 2004Inventor: Charles W. Crim

Publication number: 20040238058Abstract: An insulated duct-wrap insulating product for an air duct that incorporates a wicking media to transport condensed water on the duct surface to be evaporated into the atmosphere. A wicking fabric, or fibrous media, incorporated as part of the insulating duct wrap is in contact with the metal air duct surface. A portion of the wicking fabric extends into the interior of the air duct, typically through joints in the duct system. When water vapor condenses on the air duct surface it is transported by the wicking fabric and evaporated from the wick surface within the air stream being transported by the ducting system.Type: ApplicationFiled: October 31, 2003Publication date: December 2, 2004Inventors: Roy Shaffer, Manoj K. Choudhary, Steven F. Geiger, Charles W. Crim

Publication number: 20040238060Abstract: The invention relates to a yarn processing system (S) comprising a textile machine and at least one yarn feeding device, which are assigned to the peripheral auxiliary devices (3 to 6, 18), wherein the yarn feeding device has a computerised control device (C) that is connected by signal transmission to the auxiliary device. At least certain auxiliary devices have at least one component configured in such a way that they generate and/or receive signals. According to the invention, the yarn feeding device (F, F′) has at least one local, autonomous communication bus system (BL) for the transmission of serial data at least from and/or to the auxiliary devices, said bus system being connected to the control device (C).Type: ApplicationFiled: June 28, 2004Publication date: December 2, 2004Inventors: Jerker Hellstroem, Lars Helge Gottfrid Tholander, Niklas Wahlgren

Publication number: 20040238062Abstract: A forming fabric has a paperside warp layer and a machine side warp layer. The fabric comprises at least one set of machine side wefts and at least one set of weft triplets, the weft triplets together forming two continuous weft paths on the paperside. All of the weft triplets interweave with at least some paperside warps and at least some machine side warps.Type: ApplicationFiled: May 30, 2003Publication date: December 2, 2004Inventors: Scott David Quigley, James Michael Kramer, James Loy Brewster

Publication number: 20040238063Abstract: A forming fabric having a paper side layer and a machine side layer comprises a first set of paper side layer wefts, a second set of machine side layer wefts and a single set of warp yarn triplets. In the fabric weave pattern, each member of each triplet set of warp yarns interweaves with the paper side weft yarns to occupy in sequence segments of an unbroken warp path in the paper side surface, and each triplet in each set of warp yarns interlaces alone with at least one single machine side layer weft yarn. Each segment in the unbroken warp path is separated by at least one paper side layer weft yarn. The machine side layer interlacing points are regularly spaced. After heat setting, the fabrics typically have an air permeability typically from about 7,500 to about 10,500 m3/m2/hr. Paper products made using these fabrics have enhanced printability.Type: ApplicationFiled: March 25, 2004Publication date: December 2, 2004Inventor: Richard Stone
