A method and apparatus of forming coreless rolls of pressure sensitive adhesive tape involves the use of a mandrel assembly having a specific circumferential tape supporting segment thereon for winding tape. The circumferential tape supporting segment has a tape engaging surface portion that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel to form a tape roll, and that is sufficiently pliant to permit ready axial removal of a wound tape roll from the shaft. The innermost wrap of pressure sensitive adhesive tape about the mandrel is masked by an adhesive liner. That liner is formed from one portion of a liner/tab segment which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab forms an end tab on the outermost end of the previously formed coreless tape roll.

A method for forming an electroluminescent lamp unit. A multi-layer sheet form electroluminescent lamp, the multi-layer sheet form lamp includes a pair of sheet-form conductive layers, one of which is transparent for transmitting light emitted from the particles, an electroluminescent sheet-form layer disposed between the pair of sheet-form conductive layers and having electroluminescent particles, and a carrier substrate for supporting the pair of sheet-form conductive layers and electroluminescent sheet-form layer. The multi-layer sheet form lamp is heated at a temperature sufficient for maintaining the operational integrity of said carrier substrate and said thermoplastic layers. The multi-layer sheet form lamp is them formed into a desired three-dimensional shape.

A polymer composition comprising an anticoagulant carried in a water soluble polymer hydrogen bonded to a cellulose polymer. The composition is useful as sutures, implantable material, temporary grafts, vasculature connections and the like. The composition can be prepared by a method comprising the steps of: forming a solution in an amine oxide of a water-soluble polymer capable of hydrogen bonding, a cellulose polymer, and an anticoagulant and reducing the amount of amine oxide in the solution to solidify a solid polymer composition comprising the anticoagulant in the water soluble polymer and the cellulose polymer. The polymer compositions are particularly useful in temporary implants, sutures, grafts or the like.

An electroluminescent lamp assembly includes electroluminescent lamps of selected limited size placed and secured upon a larger printed circuit substrate employing surface mount techniques. The electroluminescent lamp assembly includes a substrate having a relatively large lamp receiving surface and relatively smaller lamps. At least one of these smaller lamps is a multi-layer sheet-form electroluminescent lamp having a sheet-form layer containing electroluminescent particles, the layer disposed between a pair of sheet-form conductive layers, one of which is transparent for transmitting light emitted from the particles. The electroluminescent lamps each have conductors exposed for engagement and connection with conductive traces on the lamp receiving surface of the substrate in a surface mounted face-to-face arrangement and are distributed in spaced-apart relationship according to a preselected illumination pattern and connected to the conductive traces.

An electrical connector is provided which has an insulating body with at least two open areas which may contain electrical conductors, such as insulated wires inserted into the open areas. The at least two open areas are positioned within the insulating body to support the electrical conductors in proximity. A connector bore is provided towards at least one area where the electrical conductors are in proximity. An electrically conductive element having conductive threads which are capable of cutting into and through insulation on wires is directed into the connector bore. The electrically conductive element with threads (or other screw-like, bolt-like or parallel edges extending from the sides of the electrically conductive element) is rotated within the connector bore so that the thread elements cut through the insulation (eventually or simultaneously of both wires) within at least one area where the conductors are in proximity. The electrically conductive element thereby establishes electrical contact between the wires. A cap or flap may be installed to cover the electrically conductive element to prevent collateral or external contact with the connected electrical wires.

A linerless double-backed adhesive tape structure is disclosed. In one embodiment the tape has three tape strips each with an adhesive coated surface and an adhesive free surface. Two of the strips are joined to a center strip along its lateral edges with the adhesive coated surfaces of the two strips overlapping and adhered to the adhesive coated surface of the center strip. Also disclosed is a method of unitizing and sealing a plurality of containers. In one embodiment a double-backed adhesive tape structure is adhered to each of the containers and the containers are stacked together with the exposed adhesive side of the tape on each container adhered to the exposed adhesive side of the tape on an adjacent container. Finally, an apparatus for dispensing the double-backed adhesive tape of the present invention is disclosed.

An electroluminescent lamp unit includes a flat deformable substrate of preselected size having smaller sheet-form flexible electroluminescent lamps secured face-to-face at preselected positions on a surface of the substrate, the lamps connected with conductive traces on the substrate. The flat substrate with secured lamps can be deformed into a desired shape to provide a relatively inexpensive and reliable electroluminescent lamp unit applicable for a wide variety of applications. The flexible electroluminescent lamps of the unit can be individually addressable and may have different colors or intensities. A method of manufacture of such units employs surface mount technology in an automated version, pick and place robots select and place the lamps as instructed, followed by ultrasonic welding or mechanical or adhesive fastening.

A selectively activated time-temperature integrating device for providing a visually observable indication of cumulative thermal exposure, in which a viscoelastic material migrates into a diffusely light-reflective porous matrix at a rate which varies with temperature to progressively change the light transmissivity of the porous matrix and thereby provide the visually observable indication. The viscoelastic material can comprise a pressure sensitive adhesive. The visually observable indication can comprise latent indicia which initially are not visible and become visible, obscurable indicia which initially are visible and become obscured, or a combination of both. Various actuating means for selectively switching the indicator from an unactivated state to an activated state are described. Also disclosed are a method for providing a visually observable indication of cumulative thermal exposure and a method for providing a time and temperature integrating device for providing a visually observable indication of cumulative thermal exposure of an object.
