Abstract: An apparatus and method for bonding wafer pairs. The apparatus includes a heated platen surrounded by a pressurization vessel. The heated platen includes channels connected to a hole which runs through the heated platen. Wafer pairs are placed on the top surface of the platen, a rubber mat is placed over the top of the wafer pairs, and a vacuum is drawn through the hole and the channels. The rubber mat compresses the wafer pairs. The platen is heated for the bonding process. The pressurization chamber is pressurized supplying additional bonding pressure to the wafer pair. Once sufficiently heated, the heated platen is liquid cooled completing the bonding process.

Abstract: A method and apparatus of manufacturing laminate for honeycomb structure. The invention includes first and second adhesive agent applying units, each of which applies an adhesive agent to a material strip in parallel strips, first and second pressing rolls corresponding to each of said adhesive agent applying units, and a layering table reciprocated by a predetermined stroke. The second stripes of the adhesive agent are displaced transversely by a half pitch from the first stripes of the adhesive agent. The adhesive agent applying units and the pressing rolls are disposed immediately above the layering table and the rolls press the material strip being fed onto the layered material strip, and are moved between an operating position and an inoperative position with relation to the movement of the layering table. The layering table is movable and a roll stand housing the pressing rolls moves in a direction opposite to that of the layering table.

Abstract: The method includes using a contoured mold (22) with copper tubing (40) coiled and embedded beneath the contoured surface. The fabric or trim cover (14) and an adhesive film (16) is placed on the mold (22) and drawn by a vacuum in to contour with the mold (22). The foam cushion (12) is placed thereon in compression. The adhesive film (16) includes a polyamide resin doped with micron sized ferromagnetic particles. Copper coil tubing (40) is energized by an oscillatory radio frequency generator (50) to produce a magnetic flux to induce eddy currents in the ferromagnetic particles to generate heat to thereby melt the polyamide resin. The adhesive film melts, creating a bond between the trim cover (14) and the foam cushion (12).

Abstract: The invention is an improved membrane press, and method of elevating a workpiece above the supporting surface of a work base. The membrane press includes a work base having a supporting surface for carrying the workpiece, and a foil-pressing frame positioned above the workpiece for heating and applying the laminating foil to the workpiece. The improvement in the membrane press includes a plurality of workpiece-lifting pedestals residing substantially beneath the supporting surface of the work base. A piston is located beneath each pedestal, and responds to the placement of the workpiece onto the supporting surface of the work base. The piston imparts an upward force on certain ones of the pedestals residing adjacent to and beneath the workpiece to raise the pedestals and workpiece upwardly above the supporting surface of the work base. The raised pedestals permit the top surface, corners, and peripheral borders of the elevated workpiece to be laminated.

Abstract: The invention provides an expandable double-walled sleeve whose space between the walls is filled with curable material and which is designed for the local support and/or reinforcement of a body vessel, absorbent material being provided between its walls which are fabricated from an essentially non-extensible material. This achieves the advantage that the curable material remains uniformly distributed between the walls of the sleeve even if the sleeve is rolled around a still unexpanded PTA balloon in order to be brought to the desired position by means of said balloon.

Abstract: The protection of the straight edges of multilayer panels (10), such as spacecraft thermal protection panels or heat shields, is ensured by an adhesive protection edging (14) having two adhesive, lateral zones bonded to the faces of the panel and a non-adhesive zone (18) placed on the edge of the panel. Following the removal of a non-adhesive protection (30b), a first adhesive, lateral zone (20b) is brought onto a working plane (22), through a slot (32), and is progressively bonded to the lower face of a panel (10) moving on said plane. The second lateral, adhesive zone is then turned down and pressed onto the upper face of the panel, after which the non-adhesive protection (30a) of said zone is removed.

Abstract: A decorated helmet is formed by applying a decoration to a side of a plastic sheet. The plastic sheet is heated and applied to a helmet shell with the decoration between the plastic sheet and the helmet shell. A vacuum is applied to the heated plastic sheet to stretch the plastic sheet and mold the plastic sheet directly about the helmet shell with the decorations sandwiched between the plastic sheet and the helmet shell.

Abstract: An incontinence electrode for controlling urinary incontinence in women is made of alternating bands of conductive and non-conductive polymers molded to form a tubular body. Electrical receptacles, formed in the molding process at the interior circumferential surface of the conductive polymer bands, accept metal contacts attached to electrical leads to make a secure and durable, mechanical and electrical connection between the conductive polymer bands and the leads. The leads are coupled to a controller and carry electrical current to and from the metal contacts which then distribute the current to the conductive polymer bands to cause a contraction of the vaginal muscles responsible for controlling urinary incontinence in women.

Abstract: Labels with release liners, including integrated labels, are manufactured in a simple manner that does not require two webs of material. A pressure sensitive adhesive is applied (e.g. patterned coated) in a first strip on a second face of a web of label material (e.g. bond paper). Then silicone release material is applied in a second strip on the second face of the web of label material so that the second strip is adjacent, but spaced from, the first strip and substantially parallel to it, a line of demarcation (about 1-25 mm wide) provided between the first and second strips, and each strip is at least about one inch wide. Then the label material is folded (e.g. plow folded while on a Webtron press) about the line of demarcation so that the first and second strips come into face-to-face contact with each other.

The sheet has opposing walls separated by longitudinally extending webs. A portion of the hinges cross the longitudinally extending webs and are formed by hot compression of at least one wall of the sheet. Another portion of the hinges are longitudinally extending and are formed by cold compression of at least one wall of the sheet.

Abstract: A hot plate for a double facer used in the manufacture of corrugated paperboard includes a substantially all copper construction which enhances thermal conductivity and heat transfer efficiency. Steam for heating the plates is provided through an array of copper tubes extending between manifolds on opposite sides of the hot plate, all in a manner which obviates the need for heavy pressure vessel construction. The hot plate is allowed to float on its supporting frame in a manner which accommodates lateral thermal expansion, and the lateral ends are tied vertically to the supporting frame to prevent thermal bowing characteristic of prior art systems.
