Abstract: Thermoplastic powder entrained in a stream of carrier gas is conveyed through a carrier gas line extending between a flame spray applicator and a remote supply hopper. A bypass line is included to divert the carrier gas before it reaches the hopper and introduce it into the carrier gas line immediately downstream of the hopper, whereby powder supply from the hopper can be terminated while the carrier gas continues to purge the carrier gas line downstream of the hopper to remove contained powder. The flame applicator delivers fuel gas, combustion air and a carrier gas-powder mixture in separate streams to maximize the quality of the flame and the surface coating. The carrier gas-powder mixture is delivered as a central stream, the combustion air as a generally concentric annular stream around the central stream and the fuel gas as an outermost generally concentric annular stream. The body member is formed with a first central bore for delivering the carrier gas-powder mixture.

Abstract: An improved columnar support for offshore drilling platforms intended for installation in a body of water such as the ocean, comprising a cylindrical shaft of unitary cemetitious construction, a frustrum shaped hollow capital having a first peripheral flange, a frustrum shaped hollow base having a second peripheral flange and seals, which may include removable plugs in the open ends of the capital and the base for creating a scuttle opening therein to admit water and sink the columnar support at a designated position on the sea floor.

Abstract: A leather adjustable stirrup strap having a plurality of apertures in a first strap portion and plate-like fastener attached to a second strap portion. The fastener has two inverted U-shaped projections for fitting in selected apertures of the plurality of apertures to form the strap into a closed loop of desired length. A locking strap sized to fit under the U-shaped projections is also provided.

Abstract: A five-layered bonded metal product comprising a top layer of aluminum alloy, a second layer of aluminum, a third layer of titanium, a fourth layer of 70-30 copper-nickel, and a fifth layer of steel. The method of producing said multi-layered product comprises the step of explosive bonding. The invention also includes a transition joint between aluminum and steel comprising interlayers of titanium and copper-nickel.

Abstract: A three-layered explosion bonded metal product comprising a layer of steel, a layer of titanium and an interlayer of 70-30 copper-nickel between the layer of steel and the layer of titanium. A method using explosive force is provided for bonding the three layers.

Abstract: A modular assembled retaining wall is constructed by placing a plurality of precast tie-back elements in laterally spaced relationship along a grade line. A novel soil retaining panel is provided. The panel includes a curved rear wall meeting a flat front wall at curved ends which mate with vertical ribs of each tie-back. A novel method is also provided for simultaneously casting two tied arch-shaped soil retaining panels out of low water-to-cement ratio concrete.

Abstract: A vein locator for locating a vein of a patient for insertion of a venous access catheter. The locator comprises a sleeve partially encompassing the vein to be located, and a ring removably attached to the sleeve. The ring has protuberances around an opening wherein the protuberances can be felt through the skin of the patient to locate the vein. The opening surrounded by the protuberances defines the vein location for insertion of the catheter. The method of locating a vein and the method of inserting a venous access catheter is also contemplated by the invention.

Abstract: A stand for reading material or sheet material comprising a back support, and a pair of side supports hinged to said back support. A reading material support member is provided between said first and second side supports. First means comprising pins are provided on said support member for attaching said rear end of said support member to said first and second side supports. Second means are also provided on said support member for attaching said front end of said support member to said first and second side supports, said second means comprising pins mounted on a movable bar. A track is provided to guide the pins mounted on the movable bar so that the distance between the pins of said first means and the pins of said second means can be varied to change the angular orientation of the support member with respect to the back support. The reading material support can also be removed so that the stand can be collapsed.

Abstract: A windmill driven pump having rotatable windmill vanes attached to a turning shaft. A disk is eccentrically mounted on the shaft so that both the disk and shaft rotate along with the vanes. Bearings selectively cooperate with the disk to transfer the rotational movement of the disk to a reciprocally movable beam. A pulley system transfers the movement of the beam to a sucker rod for a pump. A locking device is also provided which can prevent the bearings from cooperating with the disk and thus disengage the pump from the rotation of the windmill.

The compartment for receiving cartridges to be fired includes an opening for receiving the cartridges, a follower, a bias spring for urging said follower in a first direction towards said opening, and a manually actuated slide for overriding the bias spring and allowing the follower to move in a second direction away from said opening for loading and unloading of the cartridges in the compartment.

Abstract: A snowmobile electrical system having a battery conservation circuit. The system is designed to conserve battery power after deactivation of the engine using the kill switch, even if the key switch is left on. Battery power is normally consumed by continued connection of the microprocessor-based electronic engine control unit (ECU) to the battery after kill switch activation. To prevent battery consumption, the ECU monitors the electrical output of the ignition system at a position within the system wherein the output is dependent on engine speed. If the output drops to a specified level, a signal generator in the ECU is activated. Signals from the signal generator are directed to a solid state switching system which disconnects the battery from the ECU. As a result, battery consumption is controlled.
