  • Patent number: 5620544
    Abstract: 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.

  • Patent number: 5565733
    Abstract: 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.

  • Patent number: 5070606
    Abstract: A method for producing an article having a body with one or more enclosed channels extending therethrough such as for the circulation of fluids. The body is formed preferably by metal deposition about one or more fibers to generate the enclosed channels with at least one end of the fibers extending beyond the body. The fibers are then extracted from the channels in the body to leave open the channels through which fluid may be circulated.

  • Patent number: 4971251
    Abstract: A liquid spray gun including (1) a reusable air gun portion including a manually operable valve for controlling air flow; and (2) a disposable container and spray nozzle assembly including a sheet of flexible material having portions attached together and to a central portion of a tube to form a chamber, a liquid in the chamber, and an aspirating nozzle connected to the tube and adapted to be releasably coupled to the air gun portion so that upon movement of air through the nozzle liquid in the chamber will be entrained in that air and sprayed from the nozzle. The assembly can include a coil comprising a strip disposed in a plurality of wraps about an axis and having a spring temper biasing the strip to an axially extended position to form a tube like structure, with an end portion of the coil positioned around an end portion of the tube within the bag so that during spraying the tube like structure will insure that most of the liquid can be dispensed from the chamber.

  • Patent number: 4411893
    Abstract: Topical therapeutic compositions are disclosed which contain from about 0.1 to 70 percent by weight of a water-soluble tertiary amine oxide and a therapeutic agent selected from the group consisting of erythromycin, benzoyl peroxide, hydrocortisone, tetracycline, 5-fluorouracil, and propranolol. The amine oxide enhances penetration of the therapeutic agent into and through the skin.

  • Patent number: 4396128
    Abstract: A bail structure comprising an elongate polymeric strip including a handle portion, and two end anchor portions adapted to be adhered to opposite sides of a container. Each of the anchor portions includes a first part projecting away from the handle portion and a second part projecting at a right angle away from the adjacent end of the handle portion. The handle portion can be moved from a storage position adjacent an end of a container on which the anchor portions are adhered, to a use position extending across the end of the container, at which use position the handle portion may be used to suspend the container.
