  • Publication number: 20100274341
    Abstract: An introducer assembly (10) includes a guide wire catheter (12), a pusher element (16), an external manipulation unit (28) and an external sheath (30). The distal end (18) of the pusher element (16) is bonded, with adhesive or other bonding agent (32), to the guide wire catheter (12) so as to fix these components together at the distal end (18) of the pusher element (16). This reduces twisting of the pusher element (16) relative to the guide wire catheter (12) and thus twisting of any implantable medical device carried on the introducer assembly (10). This can reduce incorrect deployment of the implantable medical device and reduce instances of an abortive medical procedure. In addition, such bonding increases the torque resistance of the guide wire catheter (12) and pusher element (16) to reduce overall twisting at the distal end of the introducer assembly (10).

  • Publication number: 20100012214
    Abstract: A pipe lining material comprising an inner lining material and an outer lining material is used to rehabilitate an aged existing pipe. The inner lining material and the outer lining material are made of a tubular resin-absorbent material that is impregnated with a photo-curing resin and a thermosetting resin. The resin-absorbent material of the inner lining material has a higher density than that of the outer lining material. The photo-curing resin of the inner and outer lining materials is cured by light when the pipe lining material is irradiated with light, and the heat generated when the photo-curing resin is cured cures the thermosetting resin of the inner and outer lining materials. Since the resin-absorbent material of the inner lining material has a high density, voids are less readily formed. Even if voids are generated in the resin-absorbent material of the outer lining material, the voids will be covered by the inner lining material having fewer voids.

    Abstract: A method for lining a pipe conduit with a coated textile tubing that adheres to the inner walls of the pipe conduit by means of an adhesive. The coated textile tubing can be filled with a long pot life adhesive and the textile tubing turned inside out (inverted) while being introduced into the pipe conduit. A fast curing adhesive is substantially simultaneously applied to the inner wall of the pipe conduit in as short a distance as possible to the moving tubing inversion point. The introduced tubing is then subjected to an inner pressure to force the tubing into contact with the pipe inner wall until the fast curing adhesive has cured. Alternatively, an impregnated textile tubing can be substituted for the tubing filled with the long pot life adhesive. As a further alternative, conditions are controlled to cause curing of the adhesive only in the inverted portion of the tubing.

    Abstract: A self-adhesive purge dam for retaining purge gas around a weld zone includes a base configured to substantially obstruct an air passage leading to the weld zone and an adhesive skirt extending from the base and configured to engage portions of the air passage. An adhesive on the adhesive skirt allows the skirt to be adhered to the air passage. An optional removable backing covers the adhesive prior to installation. The adhesive skirt is deployable from a stowed position wherein the adhesive is generally disposed in an interior portion of the purge dam to an installation position wherein the adhesive can be pressed against a surface to which the purge dam is to be adhered. The purge dam can be installed by inserting it in the air passage with the adhesive skirt in the stowed position, removing the removable backing prior to or after insertion in the air passage, exposing the adhesive, and deploying the skirt to the installation position for adhesion.

  • Patent number: 7597775
    Abstract: The present invention is directed to a green fluoropolymer tube which has a wall thickness of about 250 microns or less, preferably about 200 microns or less, and more preferably about 125 microns or less. With such thinness, the green tube may be formed into a tube of expanded fluoropolymer having a wall thickness of about 250 microns or less, preferably about 200 ?m or less and more preferably about 125 microns or less. Such an expanded fluoropolymer tube is particularly well-suited for use as an endovascular prosthesis, such as a graft, or in a stent-graft, because of its flexibility and strength.

    Abstract: PVC and/or CPVC tubing and/or pipe is adhesively-secured at one end with a pipe fitting telescopably mated with each other with a uniquely effective epoxy adhesive. The resulting pipe joint is fluid-tight. PVC pipe joints meet the requirements of ASTM F1970; CPVC pipe joints meet the requirements of ASTM D2864. Such PVC and CPVC piping systems are chosen to carry cold and hot aqueous streams respectively, under pressure and elevated temperature in continuous service, both, in industrial and domestic piping systems. Such piping systems also carry more corrosive fluids for specified duration, less than 50 years.

  • Publication number: 20090208680
    Abstract: A rubber member is provided which includes an aluminum-based inner metal tube (2) (aluminum-based metal component), a film (A) chemically formed on an outer peripheral surface of the inner metal tube (2), an adhesive layer (C) provided on an outer surface of the film (A), and a vibration damping rubber (1) provided on an outer surface of the adhesive layer (C). The film (A) contains manganese oxide and zirconium oxide. In the film (A), manganese from the manganese oxide is present in a content of 10 to 30 mg/m2 on a manganese atom weight basis, and zirconium from the zirconium oxide is present in a content of 5 to 40 mg/m2 on a zirconium atom weight basis. The film (A) is free from deterioration in adhesion to the aluminum-base metal component which may otherwise occur due to heat applied for vulcanization of a rubber material, and is excellent in followability to deformation of the aluminum-based metal component.

  • Publication number: 20090183817
    Abstract: A method of manufacturing paint roller covers is disclosed in which the paint roller covers are manufactured from a seamless, tubular fabric sleeve having a backing and a pile made at least in part from a low melt fiber or yarn. The seamless, tubular fabric sleeve is placed onto a cylindrical member, and heat is applied to cause the low melt fiber or yarn in the backing and looped ends of the pile be activated to cause the backing of the seamless, tubular fabric sleeve to remain in a cylindrical configuration. The activated tubular knitted pile fabric may be finished into paint roller covers by combing and shearing the pile fabric to a desired length, beveling the edges of the paint roller covers, and vacuuming stray fibers from the paint roller covers.

  • Publication number: 20090165927
    Abstract: Installation of a flexible cured in place liner by inverting the liner with air and curing the liner with steam introduced through a perforated lay flat hose without deflating the liner between the inversion and cure. The installation is performed with an apparatus having two independently operable glands with at least one fluid inlet port installed on the line downstream of the second gland liner. As the liner reaches the distal end of the conduit to be lined, it enters a sample and porting pipe with an exhaust pipe gland and exhaust pipe and it is pierced by a rigid porting tool. Steam is then introduced into the lay flat hose to cure the resin and is exhausted through an exhaust hose connected to a controllable exhaust pipe. After curing steam is replaced with air to cool the liner, the ends are cut to restore service through the host pipe.

  • Patent number: 7540957
    Abstract: An assembly method and related subassembly for a water filter element in the housing of a replaceable filter cartridge provides for filter element insertion into the open bottom end of the housing and subsequent attachment of a retaining ring to the upper end of the element such that the element is secured against vertical drop-out until the bottom end of the cartridge can be enclosed with an end cap. The method and subassembly are particularly well adapted to cartridges in which the lower end cap is attached by spin welding. The enclosing end cap may also be provided with end rings to enhance the user's grip in cartridge installation and removal. The end rings may also be color coded for each of cartridge identification and matching to the filter head.
