Abstract: A corner bead is of the tape-on type, having an elongated metal core strip with a longitudinal arcuate nose and a pair of flanges extending outwardly from the nose at approximately a right angle. A cover strip of paper is bonded to the exterior surface of the core strip, and includes wings which project outwardly beyond the extent of the flanges. The cover strip is formed of a stock paper having high abrasion resistance, tensile strength, and which is dimensionally stable on contact with wet joint compound. The surface of the cover strip is abraded to partially loosen the surface fibers, which will increase the bond strength of the comer bead when installed on wallboard. The method of manufacturing a tape-on corner bead includes the steps of conditioning a strip of stock paper by abrading the surfaces of the paper, and then bonding the paper strip to an outward face of an elongated core.

Abstract: An adjustable receiver tube includes an elongated tube having a flat resilient strap extending within the tube from the upper end of the cylindrical side wall.

Abstract: A method of manufacturing a concrete deck form panel includes the initial step of cutting an insert within the panel, which may be removed by sliding the insert longitudinally from the panel. A pair of structural members are attached to the longitudinal sides of the insert, and then the insert is returned to the original position within the panel. A series of panels are connected to form a floor for supporting concrete, thereby forming a concrete deck system. In a second embodiment of the invention each form panel is formed by attaching a pair of structural members to longitudinal sides of a central body and then attaching L-shaped members to the structural members. A top plate is mounted to the top of the L-shaped members and the central body to form the integrated form panel.

Abstract: A tie for interconnecting a pair of parallel form panels includes an elongated strap with an end plate pivotally connected at each end of the strap, permitting the end plate to be pivoted from a position generally orthogonal to the strap to a position generally parallel to the strap. Once an end plate is pivoted to a position parallel to the strap, the end plate is pushed through a polystyrene form panel to project therefrom. The end plate is then pivoted to a position orthogonal to the strap, and pulled into engagement with the outer face of the form panel. The second end plate is pivoted, pushed through a second form panel, and pivoted to the orthogonal position, in the same manner. Concrete is then poured between the panels and allowed to harden. After the concrete is cured, a form panel may be removed by striking the end plate with a rubber mallet in a direction aligned with the longitudinal axis of the strap.

Abstract: A tie includes an elongated strap with an end plate pivotally connected at each end of the strap, permitting the end plate to be pivoted from a position generally orthogonal to the strap, to a position generally parallel to the strap. Once an end plate is pivoted to a position parallel to the strap, the end plate can be pushed through a polystyrene form panel to project therefrom. The end plate is then pivoted to the position orthogonal to the strap, and pulled into engagement with the outward face of the form panel. The second end plate on the tie is pivoted, pushed through a second form panel, pivoted to the orthogonal position, and thence the second form panel is pulled outwardly into contact with the second end plate. In this way, the tie will interconnect a pair of parallel form panels in spaced apart position, to receive poured concrete therebetween.

Abstract: A roulette game includes a conventional roulette wheel modified to include a plurality of tracks, to receive the simultaneous play of a plurality of balls. A plurality of independent tables are then provided extending from the roulette wheel, each table associated with one of the plurality of balls on the wheel. Each table includes one playing field for placing bets on a single ball of the plurality, and a second playing field for placing bets relative to the plurality of balls. In the method of playing the roulette game, a player places a bet as to the pocket or pockets on the wheel in which the plurality of balls will be located at the outcome of a spin. The roulette wheel is then rotated in a first direction, and a plurality of balls are propelled in the opposite direction along tracks in the roulette wheel. The pockets in which each of the balls falls during a spin is identified, and winning and losing bets are then determined.

Abstract: The electrode positioning mechanism includes a reversible electric motor. The motor rotates a worm gear which drives a spur gear. The spur gear is connected to an internally threaded collar which is adapted to receive an externally threaded sleeve. The sleeve can move axially lengthwise with respect to the collar. The sleeve acts as a housing for the electrode. Means are provided to retain the sleeve within the collar such that mechanical movement is restricted. The restriction in mechanical movement causes the torque applied by the worm gear to increase. The worm gear is allowed to move axially along the length of the motor shaft. The worm gear is biased into a longitudinally central position by at least one spring. As torque increases, the worm gear is moved from its central position against the urging of the spring. The worm gear is also connected to a washer with a diameter greater than that of the worm gear.

Abstract: A disk transfer apparatus includes an elongated arm which is pivotally connected at one end to a mounting block for pivotal movement through a vertical plane. A head is mounted on the free end of the arm, and has a pair of fixed, parallel jaws projecting therefrom forming a slot therebetween to receive a disk. A disk will contact the bottom of the slot between the jaws so that the forward ends of the jaws are juxtaposed through the central aperture in the disk. In this way, the disk will contact the jaws only at the edges of the inner side wall of the aperture and the outer side wall around the perimeter of the disk, during movement of the disk with the arm.
