A device comprising a bendable fibre comprising a fibre axis, a thermally expandable material and a resistance wire extending longitudinally through the fibre spaced apart from the fibre axis; wherein, in use, electrical power applied to the resistance wire causes the temperature of the resistance wire to increase.

A method of producing a multi-lumen elongate body for a medical device. Unlike known methods requiring a solid core of material inserted into each lumen to maintain patency of the lumens during manufacture, the present method obviates the need for a solid core within one or more minor lumens, which saves cost and production complexity. One or more material overlay and mesh overlay steps may be used to produce the multi-lumen elongate body, but only the main lumen may include a solid core therein during all manufacturing steps. The one or more minor lumens may each be defined by a lumen tube having a sufficient stiffness to withstand external pressure during all manufacturing steps without the need for a solid core within.

A method is disclosed for producing a piston (8) having a circumferential seal in the form of a circular cup seal (16). In a functional, installed state, the cup seal (16) has a profile consisting of a leg held in the piston (8) and aligned radially with respect to the piston longitudinal axis (19) in a radial region (17) and of a leg which is bent by approximately 90 into an axial region (18) and is aligned approximately parallel to the piston longitudinal axis (19). The cup seal (16) is mounted in a mold as a flat or arched preform (21, 21a) with a radial region (17a, 17b) which forms the approximately radial leg, aligned with the piston longitudinal axis (19). A circumferential region (18a, 18b) projecting radially beyond the mold cavity is shaped into the axial region (18) after removing the piston from the mold to obtain the functional contour of the installed state of the cup seal (16).

The present disclosure provides a flow rate measuring device including a first chip, a second chip, and a holding body. The first chip and the second chip are disposed in an intake passage of an internal combustion engine. The first and second chips detect at least one of a flow rate of an intake air and a parameter other than the flow rate. The holding body holds the second chip and protrudes into an inside of the intake passage. The second chip is exposed inside of the intake passage in a state where the second chip is covered by a filter. The holding body includes a resin portion that forms a surface of the holding body. The portion of the filter is inserted into the resin portion. The recessed portion is recessed from a surface of the resin portion. A portion of a first surface of the filter defines a bottom of the recessed portion. The second chip is positioned on a side of a second surface of the filter that is opposite to the first surface.

Method for molding a body in a mold, comprising the following steps: applying an adhesive tape to the inside of a mold, distributing the layers of material forming the body over the adhesive tape, curing the layers of material, removing the body from the mold, where the adhesive tape has a backing on one side of which a self-adhesive has been applied in the form of a polymer mixture, the polymers being constructed of 60 to 99.5 wt % of n-butyl acrylate and/or 2-ethylhexyl acrylate, 0.5 to 10 wt % of an ethylenically unsaturated monomer having an acid or acid-anhydride function, 0 to 30 wt % of one or more olefinic monomers and the self-adhesive comprises between 0 and 60 parts by weight of one or more tackifiers.

A non-metallic flange isolation gasket kit sealing flanged pipeline connections and flanged vessel connections while providing electrical isolation protection between flanges suited for high-pressure and high-temperature cathodic protection applications is presented. The invention protects flange faces from media induced corrosion and mitigates flange rotation induced fatigue and failures. The invention comprises of a retainer, a seal, and a seal pre-load structural ring. The seal pre-load structural ring is inserted into the seal, and seal outer diameter surface is joined to the retainer inner diameter surface. A second embodiment comprises of a composite gasket blank, comprising of a retainer and a seal, and a seal pre-load structural ring. The seal outer diameter surface and the retainer inner diameter surface are joined by thermal fusion bonding. The invention may further comprise one or more gasket seating stress stabilizers and/or a centering ring. Tapered retainer upper and lower surfaces decrease flange rotation.

The disclosure provides a method for the bonding of polytetrafluoroethylene sheets of various thicknesses to various surfaces. A method may include removing contaminants from a substrate for the application of the polytetrafluoroethylene sheet; applying adhesive to an etched side of the polytetrafluoroethylene sheet; and installing the polytetrafluoroethylene sheet to the substrate.

A bracket assembly suitable for use with an electronic device is described. The bracket assembly may include a bracket body having a channel. The bracket assembly may further include a membrane embedded in the bracket body and designed to allow air, but not liquid (such as water), to pass through the membrane. The membrane may be at least partially surrounded by a membrane support molded to the membrane. The membrane and the membrane support may be disposed in a molding tool to receive a material used to mold the bracket body over the membrane and the membrane support. During the molding operation, the membrane support may act as a buffer to shield the membrane from temperature and pressure increases associated with the molding operation of the bracket body. The bracket assembly may improve the ability of the electronic device to prevent liquid ingress.

A method for waterproofing blanks of shoes, gloves, items of clothing and other clothing accessories, a blank waterproofed by the method and shoes, gloves, items of clothing and other clothing accessories provided by the waterproofed blanks, the method comprising the gluing and pressing on the surface of the blank, on the side intended to remain hidden after its application, of a waterproof and breathable assembly provided by associating a waterproof and breathable functional element in the form of a flexible sheet with at least two meshes that close it in a sandwich-like manner.
