The first and second lips are further provided with bottom surfaces facing the casting surface at a standoff distance less than 0.120 inch.

Abstract: An apparatus for rapid solidification casting of molten high temperature and/or reactive metallic alloys has a heat extraction crucible for containing the alloy in liquid form. A nozzle forms an integral part of the crucible and allows for ejection of a stream of molten metal. The heat extracting crucible and nozzle are protected from the molten alloy by a shell of the alloy which has solidified and prevents reaction between the molten metal and the heat extracting crucible.

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 The molten metal is continuously solidified by the belt and the inclined surfaces and withdrawn horizontally from the mold space as a cast strip which remains unsolidified molten metal within the upper portion of the solid shell.

Abstract: A machine for casting battery grids in a continuous manner includes a rotary cylindrical drum in the outer peripheral surface of which the battery grid pattern is machined as a cavity. A shoe is arranged against an arcuate segment of the peripheral surface of the drum. An orifice slot in the shoe has an opening at the peripheral surface of the drum. Molten lead under superatmospheric pressure is directed into the orifice slot in an amount in excess of that required to fill the grid cavity on the drum through the opening in the orifice slot as the drum rotates. Means are provided in the shoe for maintaining the molten lead in the orifice slot in a highly fluid condition and for causing the lead filling the grid cavity to solidify rapidly as it is advanced beyond the opening of the orifice slot.

Abstract: Molten material is fed into an elongated outwardly open mold, moving in a predetermined path, and is thereafter conveyed by the mold movement at least partway through a region of such path over which a closure for the outward opening of the mold moves along therewith, the material concurrently being cooled to become solidified. The movements of such mold and closure cause the solidified material to be extruded through stationary die means disposed in such region. Such material may solder metal formed into a tube into which is inserted rosin, the same heat exchange medium being used both to cool the metal prior to its extrusion and to keep the rosin molten prior to such insertion thereof.

Abstract: A machine for casting battery grids has a rotary drum, the pattern of the battery grid cavity being recessed into the outer periphery thereof. An arcuate shoe is fixedly positioned against the rotating drum in sliding contact with the outer peripheral surface thereof.

The orifice slot is connected at one end to a source of molten lead under pressure and at its other end to a return line. The molten lead in the orifice slot is under superatmospheric pressure. The rate of flow of the molten lead through the orifice slot is in excess of that required to fill the grid cavity.

Abstract: Defined shapes of thin metallic sheet are continuously formed by forcing molten metal onto the surface of a moving chill body under pressure through a slotted nozzle located in close proximity to the surface of the chill body. The surface of the chill body whereon the shaped parts are formed is provided with raised or lowered domains corresponding in outline to that of the desired defined shape. As the metal is cast, as a thin sheet against the chill surface, discontinuities arise in the sheet at the walls of the raised or lowered domains defining the desired shape so that sheet product of defined shape is obtained, as if punched out from a continuous strip of the metal.

Abstract: A bearing gas sleeve coaxial with the melt ejection crucible is provided in an apparatus for making glassy alloy ribbons to provide a confluent bearing gas flow which minimizes dynamic fluctuations in the molten alloy puddle from which metallic ribbon is formed during chill block melt-spinning. The bearing gas flow causes an improved quench rate and melt puddle stabilization which results in reduced upper ribbon surface texture and improved edge definition.

Abstract: The invention relates to an improvement of a manufacturing process for making a filament directly from a molten material. The process consists of the ejection of a liquid filament which solidifies in air by making a rotating disc touch the surface of a liquid. The improvement consists in the stabilization of the meniscus which appears upon the wheel near the surface of the liquid and thereby fixing the point where the filament leaves the wheel in order to obtain a constant cross section of the filament. The meniscus is stabilized by the interposition of a body: a rod or a convex piece of a material which does not react with the melt.

Abstract: Liquid amorphous metal alloy is manufactured into shaped laminations ready for assembly in an inductive component in one process. The rotating chill surface to which the melt is delivered has high thermal conductivity metal in a pattern corresponding to the shaped lamination and is surrounded by thermally insulating material. Melt coming in contact with the high thermal conductivity metal becomes amorphous and that contacting the thermally insulating areas cools more slowly and becomes crystalline. The brittle crystalline scrap is broken away from the strip of laminations and is collected and recycled to the melt.

Abstract: Improvement in apparatus for making metal filament by depositing molten metal onto the peripheral surface of a rotating annular chill roll includes provision of a stationary housing surrounding the peripheral surface of the chill roll in an arc, covering the segment beginning at the vicinity of the point of deposition of the metal onto the chill roll and terminating at a predetermined point of stripping of the solid filament from the chill roll, and defining a gap between the peripheral surface of the chill roll and the interior of the housing, together with means for introducing a fluid into the gap for passage therethrough in the direction of rotation of the chill roll. In operation, cocurrent passage of the filament and the fluid through the gap effects controlled retention of the filament on the chill roll and fixes the point at which the filament is stripped from the chill roll.
