Abstract:
The present invention provides a tubing assembly having a sidewall having a first layer. The first layer is fabricated from a first polymer blend comprising a first component of a material not thermally responsive to laser beam and selected from the group consisting of polyolefins, ethylene and lower alkyl acrylate copolymers, ethylene and lower alkyl substituted alkyl acrylate copolymers, ethylene vinyl acetate copolymers, polybutadienes, polyesters, polyamides, and styrene and hydrocarbon copolymers. A second component of the blend is a laser responsive material having low solubility in aqueous medium; and the blend being sufficiently thermally responsive to exposure to a laser beam having a wavelength within a range of wavelengths from about 700 nm to about 1500 nm to melt upon exposure to the laser beam for a short period of time. The assembly also has an end cap film covering the fluid outlet.
Abstract:
A thermal polymer-bonding method includes initially placing into contact certain polymer-based first and second solid media at a first junction. A first superficial portion of the first solid medium is liquefying through the application of thermal energy to the first junction. The liquefied first superficial portion is superficially or topically applied to the second solid medium whereafter the topical application may be solidified via the action of cooling or withdrawal of thermal energy from the first junction. The solidification of the liquid elements, having maximized surface area contact between opposing media, bonds the first solid medium to the second solid medium. A third polymer-based solid medium may then be placed into contact with the first solid medium at a second junction, whereafter certain select second superficial portions of the first and third solid media may be liquefied, and re-solidified to bond the third solid medium to the first solid medium.
Abstract:
The invention discloses a welded seam (80) between the two edges of two laminates (1a, 1b), each laminate comprising a waterproof functional layer (50) and a textile layer (30). The textile layer (30) comprising a first component and a second component, the first component being stable to a first temperature and the second component melting at a second temperature. The seam (80) is formed by the melted second component and the non-melted first component of the textile layers of each laminate and the edges are in a substantially edge-to-edge buttes orientation to each other. In this case a waterproof, durable seam with very small dimensions is created.

Abstract:
A method for producing a tight joint between a multi-layer synthetic resin material and a filter medium by selectively melting a layer of the synthetic resin material which has a different thermal absorption capacity in comparison with the other layers by heating the synthetic resin material with infrared radiation, and then fusing the melted synthetic resin layer to the filter medium. A filter element produced by the method of the invention is also disclosed.
Abstract:
A method and apparatus for joining the ends of two profile sections (5, 6) such as two sealing, trimming or finishing strips for use in motor vehicle body construction, is shown. The two profile sections (5, 6) are clamped in respective retaining devices (18, 20) and a length of heat-responsive foil-like material (24) is unwound from a roll (22) into a position between the facing ends of the profile sections. Heaters (26-32) carried by a heater unit (34) are then moved into position between the ends of the profile sections (5, 6) and the foil (24). The outermost heaters (26, 30) heat the ends of the profile sections, and the innermost heaters (28, 32) heat the foil. The heaters (26 to 32) are then withdrawn, and the two retaining devices (18, 20) are then moved towards each other so as to move the ends of the two profile sections into contact with opposite sides of the heated foil (24) which thus heat-bonds the ends of the profile sections together. The retaining devices (18, 20) are then opened to release the joined profile sections. The heaters (26 to 32) are non-contact type heaters to avoid contaminating the foil or the ends of the profile sections. The use of the separate heaters allows the foil (24) to be heated to a temperature which is different from that of the ends of the profile sections, to achieve optimum bonding.

According to a bonding method of heat-welding a plurality of components in a predetermined lengthwise direction by vibration of an ultrasonic vibrator, the plurality of components are fixed such that their bonding positions are aligned, the ultrasonic vibrator is oscillated, and the plurality of components and ultrasonic vibrator are moved relative to each other in the lengthwise direction, thus performing heat welding.
Abstract:
A method for optically coupling a thermoplastic material to an outer surface layer of an organic, dielectric, optical film and the resulting optical filter. Initially, a dielectric film is selected that includes (i) repeating optical layers of at least two polymers having different refractive indexes from each other, (ii) an exterior film surface, (iii) a refractive boundary along the exterior film surface, and (iv) a delamination threshold based on total thermal energy delivered to the film. A thermoplastic material which is miscible with the exterior film surface is fused to the refractive boundary with thermal energy below the delamination threshold to form a polydisperse region having a higher optical transmission than the refractive boundary. Add-on filters in the form of hardcoat layers, anti-reflection layers, holograms, metal dielectric stacks and combinations of these may be combined with the thermoplastic-film construct.
Abstract:
The present invention provides a heat-sealable polyester composition having an amorphous processing window ranging from a Tg in the range of about 40null C. to about 70null C., to a Tcg in the range of about 70null C. to about 150null C. The composition preferably contains a mixture of poly(ethylene terephthalate) homopolymer or copolymer and poly(trimethylene terephthalate) homopolymer or copolymer, either as a physical blend or as a copolyester oligomer or polymer prepared from the respective monomers. The resulting composition is heat-sealable at low temperatures, retains barrier properties and is non-flavor-scalping.
Abstract:
As the first object, the present invention intends to provide high-pressure composite pipes which show remarkable pressure resistance and optimum applicability in various uses and which can be economically manufactured in a light weight. To achieve this object, a high-pressure composite pipe of the present invention comprises a pipe-shaped inner layer made of a synthetic resin, a reinforcing layer made of a stretched polyolefin resin sheet and wound on an external circumferential surface of the inner layer, and an outer layer made of a synthetic resin and disposed on an external circumferential surface of the reinforcing layer. The winding direction of the reinforcing layer is oriented at a predetermined angle relative to the axis of the pipe. Between the inner layer and the reinforcing layer and between the outer layer and the reinforcing layer, adhesion layers having affinity to these layers are interposed.
