  • Patent number: 6422884
    Abstract: A pre-wired electrical component for a flexible wiring system has a housing, a flexible power supply cable connected in strain relieving relation to the housing within an inlet opening in the housing, at least one power supply outlet member mounted in an associated power outlet opening in the housing and a rotational circuit selector which includes a first connecting member mounted in fixed position on and exposed externally of the housing. Electrical buses disposed within the housing and separated from each other by a dielectric bus separator electrically connecting the power supply cable to the power supply outlet member and to the first connecting element.

  • Patent number: 5529809
    Abstract: A metal spray apparatus is provided with a supersonic nozzle. Molten metal is injected into a gas stream flowing through the nozzle under pressure. By varying the pressure of the injected metal, the droplet can be made in various selected sizes with each selected size having a high degree of size uniformity. A unique one piece graphite heater provides easily controlled uniformity of temperature in the nozzle and an attached tundish which holds the pressurized molten metal. A unique U-shaped gas heater provides extremely hot inlet gas temperatures to the nozzle. A particularly useful application of the spray apparatus is coating of threads of a fastener with a shape memory alloy. This permits a fastener to be easily inserted and removed but provides for a secure locking of the fastener in high temperature environments.

  • Patent number: 5484244
    Abstract: A threaded fastener with a shape memory alloy (SMA) coatings on its threads is disclosed. The fastener has special usefulness in high temperature applications where high reliability is important. The SMA coated fastener is threaded into or onto a mating threaded part at room temperature to produce a fastened object. The SMA coating is distorted during the assembly. At elevated temperatures the coating tries to recover its original shape and thereby exerts locking forces on the threads. When the fastened object is returned to room temperature the locking forces dissipate. Consequently the threaded fasteners can be readily disassembled at room temperature but remains securely fastened at high temperatures.A spray technique is disclosed as a particularly useful method of coating of threads of a fastener with a shape memory alloy.

  • Patent number: 5289704
    Abstract: An improved cable lock having a lock housing and a flexible shackle has a longitudinally elongated latch housing with a cylindrical side surface in which is formed a latch reception slot, receiving an L-shaped latch body. The latch body fits flush with the housing surface and is released by rocking one of its arms. A resilient ring is carried on the axis of the lock housing and has its circumferential surface exposed along the cylindrical side of the lock housing. A mechanism selectively compresses and decompresses the ring, respectively causing the ring to expand or retract radially for friction locking into a storage tube. A clamp is provided for mounting the storage tube into the seat post of a cycle, and a guide tube assists passage around the bend.
