Abstract: A composite metal article is made by placing a low melting temperature metal to serve as a core within a shell of a high melting temperature metal and by containing and sealing the core within the shell. The assembly constitutes a containerized ingot which is then transported to a forming die where the containerized ingot is heated to soften the core and is then formed to the shape imposed by the die. During the cooling period, the shell is reformed to the core to maintain tight contact and to promote bonding.
Abstract: A treatment for a fishing lure is formed by the combination of a water insoluble carrier such as silicone grease and a water soluble chemical composition. The water soluble chemical composition is one which upon solution with water generates heat. Particularly suitable chemical compositions include sodium hydroxide and magnesium chloride. The treatment is applied to a fishing lure such as a fly. The fly is cast into water and the physical action of the water causes the chemical composition to be exposed to water thereby dissolving the chemical composition. As the chemical composition dissolves it generates heat at the surface of the lure. This heat is detected by fish which strike at the lure. This treatment is effective for a wide variety of lures and for catching a wide variety of different fish species.
Abstract: Apparatus for forming closed loops or eyes at opposite ends of a length of wire especially useful in the manufacture of fishing lures wherein a plurality of attractive objects (beads, etc.) are strung on the wire between the closed loops or eyes. The apparatus provides mechanism for forming one straight end portion of the wire into a generally V shape to provide an open loop at the apex of the V, following which a twisting mechanism engages and twists the loop to wrap one leg of the V several times about the other leg so as to close the loop and thereby to produce an eye. The wire is turned end for end and the operation of the mechanism is repeated to form an eye at the other end of the wire.

Abstract: In continuously casting molten metal into cast product by a twin-belt machine, it is desirable to achieve dramatic increases in speed (linear feet per minute) at which cast product exits the machine, particularly in installations where steel cast product is intended to feed a downstream regular rolling mill (as distinct from a planetary mill) operating in tandem with the twin-belt caster. Such high-speed casting produces product with a relatively thin shell and molten interior, and the shell tends to bulge outwardly due to metallostatic head pressure of the molten center. A number of cooperative features enable high-speed, twin-belt casting: (1) Each casting belt is slidably supported adjacent to the caster exit pulley for bulge control and enhanced cooling of cast product. (2) Lateral skew steering of each belt provides an effective increase in moving mold length plus a continuity of heat transfer not obtained with prior art belt steering apparatus.
