A method for producing a composite glass pane, includes placing a first glass pane having a thickness less than or equal to 1 mm on a support mould, wherein the first glass pane is curved into a shape determined by the support mould; placing at least one thermoplastic film on the first glass pane; placing a curved second glass pane having a thickness greater than or equal to 1.5 mm on the thermoplastic film; and joining the first glass pane to the second glass pane via the thermoplastic film to form a composite glass pane by lamination.

The invention relates to an apparatus (10) for embedding a continuous elastic cord (11) along an edge of a continuous plastic sheet (12). The apparatus comprises an adhesive applicator device operable to apply an adhesive (16) along the edge of the plastic sheet, a folder device (18, 20, 34) operable to provide a folded edge of the plastic sheet (12) so that the adhesive is within the folded edge, and a feed device (24) having a tension device (30) operable to feed the elastic cord (11) in tension into the folded edge so that the elastic cord (11) is in contact with the adhesive of the edge. A bonding device (38) is operable to activate the adhesive of the folded edge to bond the elastic cord (11) in tension to the adhesive within the folded edge and to bond the folded edge to the plastic sheet (12). The invention also relates to a plastic sheet having an elastic cord at an edge thereof, a method for manufacture of said plastic sheet, and products or covers made from said plastic sheet such as oversleeves, overshoes, hair nets or bin liners etc.

A process of constructing an air tight and water tight seam, comprising cutting a sheet of selected material into two or more panels, sealing the panels at respective selected edges using an ultrasonic machine to form a seam, overlaying the seam with a tape made of the same selected material, and sealing the tape and seam using a radio frequency (RF) welding machine.

To achieve universal welding of thermoplastic workpiece parts with simple equipment, an infrared light transmission welding method is disclosed in which simple polychromatic, incoherent infrared light is generated by a simple infrared light source and is directed through a first workpiece part to a weld point for the purposes of connection to a second workpiece part. In particular, the infrared light is directed through a transparent bracing element.

A moisture-curable hot-melt adhesive composition is disclosed. This moisture-curable hot-melt adhesive composition contains: a urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having two or more isocyanate groups; and a modified urethane prepolymer including a polymer chain, which includes a structural unit derived from a polyol and a structural unit derived from a polyisocyanate, and having one or more isocyanate groups modified with a castor oil monool.

A method for a radome structure having a heating and a light emitting function according to the present invention comprises forming a three dimensional shape with a film part comprising a film, and a light emitting circuit and a heating circuit printed on the film in a stack; cutting the film part, and integrating an upper cover, a lower cover, and the film part disposed between the upper and the lower cover, into one body using one of a bonding process or an injection-molding process.

A protective braided sleeve and method of construction thereof is provided. The sleeve includes a seamless, circumferentially continuous, tubular braided wall having a cavity extending lengthwise along a central longitudinal axis between opposite ends. The wall includes a plurality of yarns braided with one another, with at least one or more of the yarns including a bicomponent yarn including a core and an outer adhesive sheath adapted to be selectively melted to bond the wall to an elongate member extending through the cavity.

The present invention is a system and method facilitating the application of PVC primer or PVC cement to the inner surfaces of PVC unions, PVC sleeves, and the outer surfaces of PVC pipes. The invention consists of a PVC primer or PVC cement reservoir, a method of filing the PVC reservoir, and forcing the PVC primer or PVC cement through a series of tubes and holes in the apparatus and into a foam applicator which transfers the PVC primer or PVC cement onto the inner surface or onto the outer surface of a PVC union, PVC sleeve, or PVC pipe to a predetermined depth thus reducing waste of the PVC primer or PVC cement. The foam applicator housing contains a foam applicator specifically for applying PVC primer or PVC cement to either the inner surface of a PCV union, PVC sleeve, or to the outer surface of a PVC pipe giving a uniform application of PVC primer or PVC cement.

The present invention provides a method of manufacturing a pipe liner for lining the inside of a pipe, for example a water or sewerage pipe requiring repair. The pipe liner is mainly formed of a fabric sleeve, or a plurality of fabric sleeves, and comprises a fluid-proof barrier coating on the inside surface of the pipe liner. The method involves arranging a strip of carrier material comprising a liquid sealant inside the fabric sleeve of the pipe liner and in registration with two opposing side edges of the sheet of fabric, facing an inner barrier coating of the fabric sleeve. The method can advantageously provide such a pipe liner with an inner barrier coating without everting the pipe liner after manufacture. The present invention may also provide a way of avoiding internal cross-welding of said pipe liners and a method for testing the integrity of the barrier coating of said pipe liners. The present invention also provides an apparatus for carrying out these methods.

A bonding method for bonding an adherend with a high-frequency dielectric heating adhesive sheet is provided. The adherend includes a fluorine-containing surface at least containing fluorine on a surface thereof. The high-frequency dielectric heating adhesive sheet includes a high-frequency dielectric adhesive layer including a thermoplastic resin and a dielectric filler. A surface free energy of the high-frequency dielectric adhesive layer is in a range from 15 mJ/m.sup.2 to 30 mJ/m.sup.2. A melting point of the high-frequency dielectric adhesive layer is in a range from 110 degrees C. to 300 degrees C. The bonding method includes bringing the fluorine-containing surface of the adherend into contact with the high-frequency dielectric adhesive layer and applying a high-frequency wave to the high-frequency dielectric adhesive layer to bond the high-frequency dielectric heating adhesive sheet to the fluorine-containing surface.
