Abstract: A device for use in drawing the bowstring of an archery bow and triggering release of the bowstring. A hollow body which fits in the hand carries a pivotal holding member which is held by a pivotal linkage bar in a cocked position wherein the bowstring can be drawn. A cord is passed around the bowstring and looped over the holding member. A roller bearing is carried on the holding member to reduce the friction, wear and finger pressure required to release the bowstring and to provide a smooth release. A trigger arm pivots the linkage bar to release it from the roller bearing, thus releasing the bowstring.

Abstract: An electric heater construction which significantly reduced the possibility of electrical shock to a user thereof. This electric heater includes an outer casing with an open front, a protective grille mounted over the open front of the outer casing, a reflector assembly mounted within the outer casing and a heating element enclosure mounted to the reflector assembly such that it is electrically insulated therefrom. A ribbon-type of heating element is mounted within the heating element enclosure. If any portion of the heating element should break or for any other reason become disengaged from the insulated mounted structure, the heating element enclosure effectively prevents it from coming in contact with any non-insulated portion of the device which is readily accessible to a user of the heater thereby protecting a user of the device from electrical shock.

Abstract: A method and apparatus for use in an outside collection baghouse to identify defective filter bags. Each filter bag is equipped with a sensing head adjacent the open mouth of the bag. Each sensing head includes a pair of optical fibers having free ends disposed in the path of gas flowing out the bag mouth. Light is applied to one optical fiber in each pair and the amount of light reaching the other optical fiber is sensed to provide a measurement of the amount of light intercepted by particulate matter leaking through the bag.

Abstract: A thermal insulating material which includes silicone coated perlite providing thermal insulation, powdered perlite to fill in the gaps between the silicone coated perlite particle, and a specially formulated binder for the perlite. The binder has a powder portion comprising a mixture of gypsum and cement for strength and a liquid portion comprising polyvinyl acetate, a colloid and water. After these materials are mixed in proper proportions, water is added to provide the fluidity necessary for application, such as by spraying or molding into prefabricated panels.

Abstract: A tire repair device which vulcanizes an uncured rubber repair plug built in a damaged area of the tire. The frame of the device is in the form of a C-clamp having a heated backing plate which opposes a heated pressure pad. The pad is carried in a cylinder which also receives a sealing piston forming a pressure chamber behind the pad. Air under pressure is applied to the pressure chamber to force the pressure pad against the damaged area of the tire during vulcanization. The pressure pad is flexible in order to conform to the tire surface against which it is pressed in opposition to the backing plate.

Abstract: A method and device for collecting solar energy is the subject of this application. A glass cloth coated with a light absorbing resinous material is utilized as the collector panel. A glass cloth coated with a translucent resinous material is the preferred material for a cover panel that is disposed in spaced relationship to the collector panel. A framework holds the two cloth layers in spaced planar relationship and a heat exchange medium is placed in contact with the collector panel. The device is used by placing it in direct sunlight, preferably at an angle to maximize the effects of the solar radiation. Radiation striking the light absorbing glass cloth is quickly dissipated by the glass fibers thereby heating the transfer medium. The resinous material, preferably black for the collector panel, provides a highly absorptive surface for the solar radiation and also protects the glass fiber of the cloth from deterioration as a result of radiation or corrosion.

Abstract: A method and apparatus for utilizing a horizontal disc having a plurality of guide vanes extending in a curvilinear path with each vane terminating in an end portion that is substantially parallel to a tangent to the disc. A plurality of impact surfaces are provided in the same horizontal plane as the disc with each surface being substantially linear and extending transversely of the path of travel of a kernel impelled by the disc. The method includes locating the impact surfaces away from the periphery of the disc a sufficient distance so as to preclude application of crushing forces to the kernels as the latter pass between the disc and the surface. The kernels are fed onto the disc at a point near its center from an overhead position at a carefully controlled rate whereby each kernel is aligned by centrifugal forces as it moves along the guide vane so as to expose one of the side edges of the kernel for contact with one of the impact surfaces.

Abstract: The invention related to an apparatus for lifting, handling, transporting and unrolling large round hay bales. Preferably said apparatus is employed on the bed of a pickup or truck and includes a frame mounted on the pickup bed with a beam pivotally mounted thereon and with arms pivotally mounted on the beam. The arms have bale penetrating members mounted or fixed thereon. First power actuated means operably pivot the beam in an arc about the rear end of the pickup toward and away from the ground. Second, power actuated means for pivoting the arms and penetrating members about the ends of the beam toward each other in such fashion as to squeeze a bale sufficiently to allow the first power means to lift the bale from the ground, and to pivot away from each other to release the bale. The bale penetrating members are mounted on the arms to allow a bale to be unrolled or distributed.

Abstract: An elongate flexible cord cooperates with a plurality of coil springs to interconnect golf club head covers. The cord is passed through eyelets attached to the head covers. The coil springs are sleeved over the cord and extend between adjacent eyelets to resist tangling of the cord while permitting it to bend as the head covers are removed and replaced on the club heads.

Abstract: A rub rail assembly for a vehicle such as a boat is the subject of the present invention. An extrusion presents a channel that receives a resilient bumper strip. The bumper strip is designed so that deformation of it in an inwardly direction will actually lodge the strip more firmly within the channel. An integral extension of the channel presents a coupling for securing a line to the rail assembly. A second coupling is adapted to be complementally joined with the first coupling for attaching the line.

Abstract: A caliper rule device capable of measuring the inside and outside dimensions of objects which vary widely in size. A block and an elongate bar are attached to a scaled rule and to a slide member on the rule. The block has a pair of openings for alternately receiving a pin, depending upon whether an inside or outside dimension is to be measured. The bar has a plurality of spaced openings along its length for mounting a second pin.

Abstract: A stand device which includes a lift mechanism for raising paraplegic patients from a wheelchair to a standing position. The stand is mounted on caster wheels and includes a platform on which the feet of the patient are received. The lift mechanism includes a pair of electric actuators and a linkage which raises and lowers a pair of lift arms upon extension and retraction of the actuators. The lift arms carry a sling which is drawn behind the patient to lift him to a standing position on the platform when the actuators are extended.

Abstract: A portable winch includes a base plate which is adapted to be quickly and easily coupled with and uncoupled from a bracket attached to a utility pole. The base plate hangs on the bracket and requires no tools or clamps to maintain the connection. The base plate and bracket have cooperating portions which stabilize the base plate in its operating position and prevent rocking, swinging or swaying. The winch can be supported so that the winch cable drops either on the outside or inside of the drum, thus to change the spacing of the cable from the pole. The control means for operating the winch can be carried on the basket of an aerial boom by a bracket which hangs on the lip of the basket. The bracket includes a support tongue on which the winch can be hung during its travel to and from the pole. Alternately, the winch can be powered by a hand drill detachably coupled with the winch drive and held by a worker in the basket.
