  • Patent number: 4434836
    Abstract: Semiannular mold space is defined by a pair of rotary wheels and an endless belt trained around circumferential surfaces of the wheels. Molten metal is injected into the mold space upwardly so that the molten metal is statically poured into the mold. The circumferential edges of the opposing surfaces of the wheels have inclined surfaces in such a manner that the width of the mold space becomes narrower in a direction toward the axis of the wheels. The molten metal is continuously solidified by the belt and the inclined surfaces and withdrawn horizontally from the mold space as a cast strip which remains unsolidified molten metal within the upper portion of the solid shell.

  • Patent number: 4431599
    Abstract: A method and apparatus for the continuous melting of silicon for use in semiconductor devices, the method tending to reduce the time and expense associated with conventional melting and forming. The method for melting silicon comprises charging silicon into a melting vessel having a drain therein, heating the silicon in the vessel to a temperature above the melting point of silicon, and allowing the molten silicon to pass through the drain out of the vessel.

  • Patent number: 4430880
    Abstract: An apparatus for straightening suspension bars removed from cathode plates includes a horizontal press, a vertical press, a vertically movable stop plate, and an ejector in the horizontal press. The horizontal press pushes the suspension bar against the stop plate when the stop plate is in its upper position, and ejects the straightened suspension bar laterally when the stop late is in its lower position.

  • Patent number: 4428413
    Abstract: A melting pot reservoir for non-ferrous metals and the like to be die cast in a cold chamber mold is provided with a pumping mechanism having a displacement plunger for metering out by displacement from the reservoir an exact volume of molten material into the mold. This same plunger is provided with a vernier adjustment and accompanying control circuit that automatically moves the plunger an increment into the molten material after each charge the precise amount to restore the molten material level to a predetermined optimum datum level for delivery of exactly the precise amount of charge into the cold chamber.

  • Patent number: 4425730
    Abstract: An improved artificial fishing lure for top water or surface fishing of the general type sometimes referred to as the "buzzbait" variety. The body of the lure has a forward section of hull shape provided with at least one keel or fin extending downwardly at the trailing end of the hull. The rearward section of the lure body is a solid shank with a hook attached at its trailing end and suitable for affixing various types of artificial or natural baits. The body of the lure has a flat surface forming a bend at an angle of 120.degree. to 170.degree.. The keel or fin, centered beneath the bend at the trailing end of the hull, has a circle painted on each side so as to imitate an eye. Two bulges are disposed in the lower surface of the lure body between the bend and the fin for the purpose of adding stability to the lure body. A loop is affixed proximate the forward end of the hull for attaching the end of a fishing line. The loop is formed with an upper leg disposed rearwardly at an angle.

  • Patent number: 4424855
    Abstract: In the equipment for continuous casting of steel, an improved method for cooling a continuous cast slab or the like by which a hot slab can be transferred directly to a rolling step. In accordance with the improved method, the continuous cast slab is subjected to indirect cooling by means of cooling a series of guide rolls with a gas-liquid mist, or if the equipment length is limited, the slab is subjected to direct cooling by means of a gas-liquid mist cooling step, and then to the indirect cooling step in a subsequent process.

  • Patent number: 4423763
    Abstract: A compact injection assembly for die casting machines is disclosed. The assembly includes a small reservoir or pot for retaining a molten casting metal delivered thereto from a remote source. The assembly includes a cylinder with a piston and shot chamber therein, a nozzle and interconnecting conduit to the shot chamber. The assembly is supported by a single swivel socket arrangement directly below the shot chamber and cylinder. Horizontal outrigger arms are utilized to orient the assembly in its proper vertical position.

  • Patent number: 4418738
    Abstract: A device and a method for automatically tightening spokes in spoke wheels. The device of the invention is used with a spoke wheel comprising a hub, into which spokes have been passed and extend through a wheel rim and are each provided with a loosely threaded spoke nipple at the outside of the rim. The device comprises means for clamping the hub and for engaging the outside and the edges of the rim as well as coupling means driven by prime movers for tightening the spoke nipples. The method proposes the steps of securely clamping the hub, securing the outside of the rim, subjecting the rim to a force in such manner that it becomes positioned in a single plane, and tightening each of the spoke nipples to an individual predetermined tightening torque.

  • Patent number: 4402471
    Abstract: A non-rotatable arbor, fastened by belt to waist-line of fisherman and used in combination with conventional fly-reel, onto which shooting-monofilament is wound by hand for axial departure on subsequent forward cast, thus enabling much longer casts by eliminating need for shooting-head during forward trajectory to pull coils of said monofilament, conventionally suspended from mouth or left-hand of wading fisherman, from water having appreciable viscosity and surface-tension.
