  • Patent number: 5733607
    Abstract: A method and apparatus for coating and curing fiberglass sleeving with an ultraviolet light curable acrylic includes the steps of singeing the fiberglass sleeve at a singeing station and thereafter, cooling the sleeve. The fiberglass sleeve is then coated with an ultraviolet light curable acrylic resin. Thereafter, the coated fiberglass sleeve is cured by passing it through a curing station wherein the sleeve is subjected to ultraviolet light radiation about its entire circumference. The process is speed adjustable and further, the intensity of the light emitted from the ultraviolet light source may be varied so that the system is tuned to cure fiberglass sleeves of any diameter up to approximately 1.00 inch.

  • Patent number: 5596793
    Abstract: An abrasion resistant slide fastener includes a coupling element attached to a support tape by stitching looper and needle threads to secure the coupling element and a filler cord, extending through the coupling element, to a support tape. The looper thread has an upper portion which engages an upper shank of the coupling element and a lower portion which engages the needle thread within the filler cord. The needle thread is stitched at a greater tension than the looper thread and secures the looper thread, the coupling element and the filler cord to the support tape. The upper portion of the looper thread, engaging the upper shank, is heated until it melts from the upper shank of the coupling element, thus eliminating the looper thread exposed to wear and forming anchor portions which engage the filler cord. The needle thread and the lower portion of the looper thread are not directly exposed to the heat source and remain substantially intact within the filler cord.

  • Patent number: 5481919
    Abstract: A pressure transmitter converts input pressures on the order of 0.000.15 inch of water column to proportional electrical output signals. A housing defines an open internal chamber and a substantially constant area shaped membrane spans the chamber and is secured about its perimeter thereto, dividing it into a convex side and a concave side. The convex side of the membrane forms an input side adapted to receive an input pressure. A beam is mounted for pivotal movement on the concave side of the membrane. One end of the beam supports a mechanical column which contacts the membrane and asserts a slight upward force on it. The opposite end of the beam mounts a reflector which is mounted directly over a photomicrosensor which outputs a voltage signal proportional to the movement of the reflector. A second photomicrosensor outputs a constant reference output voltage. A comparator receives both photomicrosensor outputs and outputs a voltage signal proportional to the difference therebetween.
