Abstract: Disclosed is reusable form for constructing concrete cantilevered decking around a swimming pool of any shape. The form includes an anchoring member, a plurality of adjustable brackets connected to the anchoring member, and a pair of long flexible members lying between the anchoring member and the brackets. One of the flexible members has a width substantially equal to the desired overhang of the cantilevered decking while the second flexible member extends in height above the first flexible member to the desired thickness of the cantilevered decking. In operation, the form is rigidly connected via the anchoring member to the top portion of the walls of the pool. The adjustable brackets provide a means for moving the second flexible member to the desired thickness and grade of the overhang. And after the decking has hardened, the form is removed for reuse on other pools.

Abstract: A mold for forming an article having a complex shape such as a unitary sole and heel tread member for a shoe and method of making same wherein the article to be cast is formed from a material which is injected into the mold in a hot fluid form. The mold for such an article comprises an upper and a lower mold member, which together define a complete shoe sole mold cavity. Each upper or lower mold member may consist of several intermating sections. The lower mold however, comprises a cavity having sufficient depth around its periphery to permit insertion of an inverted decorative welt plus a second decorative piece placed against the wall of the cavity. The upper mold has a cavity which basically defines the tread of the sole, and the two molds interface to provide a tight seal during the shoe sole molding operation.

Abstract: An example of the shock resistant transparent polymer sphere is a billiard or pool ball. The molding apparatus includes lower and upper mold halves defining juxtaposed concave hemispherical surfaces to define a spherical mold cavity with a top fill opening on the upper mold half. Interlocking of the mold halves together is accomplished by tongue and window structures circumferentially spaced about the meeting points of the two halves at 120.degree.. A holder in the form of an annular ring is provided for supporting a central disc provided with a symbol on each of its opposite faces. The design is such that the ring when positioned in the spherical cavity defined by the mold halves supports the disc with its center coincident with the center of the spherical cavity. The molded sphere is made by a single pouring operation of resin through the fill opening, the disc and ring being encapsulated within the sphere.

Abstract: The top surface edges for a ski of plastic material with a foam material core are produced by first placing the structural parts of the ski in position in a mold and thereafter filling the hollow spaces in the closed mold with an expandable synthetic foam material to form the core and set the structural parts of the ski. An auxiliary strip supports the structural parts in the mold and has a flange which extends beyond the side surfaces of the mold. The flange of this auxiliary support strip is extended outwardly a greater distance from the mold side walls and has angled portions which are lodged in a groove in the top edge surface of the mold box to hold the support strip and structural parts of the ski firmly in their proper position during the foam expansion in the mold. The portions of the auxiliary support strip are severed after the ski has been molded.

Abstract: In pipes and the like of relatively heavy section, a boss is formed on the side of the pipe or section by drilling a hole in the pipe, forming a mold around the hole with the hole in relatively vertical position and depositing in the mold and against the walls of the pipe, thereby joining to those walls, electroslag metal which forms a boss on the pipe.

Abstract: A process for producing mass filters for use in mass spectrometers. Several electrodes having precisely shaped surfaces must be held in precisely determined positions with respect to each other. Insulators are placed into position on the surface of a mandrel and a layer of metal is deposited over the mandrel and insulators to form a composite unitary structure, including the electrodes. The deposited metal overlying the insulators is then removed, electrically isolating the electrodes.

Abstract: A flat contact terminal for use in small switches is disclosed which is constructed to prevent flash, or escapement of material from a mold, when the contact terminal is insert-molded into the plastic base of the switch. The contact terminal is deformed to provide angled surfaces on the contact terminal at the upper and lower surfaces of the base where the terminal extends from the base so that the angled surfaces of the contact terminal are wedged tightly against corners of the mold, thereby preventing the escape of plastic material from the mold during molding of the base around the terminal.

Abstract: An insert comprising a body to be embedded in concrete and having a prong smaller in size than said body, connected at one end to said body by a frangible neck. The prong has external ridges and is adapted to be driven by a hammer into an undersized opening in a mold to securely mount the insert in place. After the concrete has set, the prong is automatically broken off, i.e., separated from the embedded portion of the insert, as an incident to the stripping of the mold from the work.

Abstract: The invention is concerned with apparatus for manufacturing gas turbine engine components e.g. guide vanes and blades, in dense silicon nitride starting with silicon nitride in a powder form.Guide vanes are usually in the form of an aerofoil portion and two shroud portions and according to the invention, the aerofoil portion is made in a first mould by hot pressing a mixture of silicon nitride powder and a fluxing agent, such as magnesia. The formed aerofoil is placed in a second mould so that each end extends partly into a space which is to be filled with a further mixture of silicon nitride powder and a fluxing agent. The further mixtures are hot pressed both to form the shroud portions and to amalgamate the shroud portions with the aerofoil portion.Features, such as, flanges and webs can be formed in the shrouds during the moulding process or they can be machined into the shrouds after the vane is removed from the second mould.

Abstract: A method and apparatus for manufacturing high-frequency coil devices, wherein a solid cylindrical rod-like mandrel having a coil element loaded thereon is inserted between lower and upper molds each of which is provided with a resilient layer, so that an annular cavity is defined between the peripheral surface of the mandrel and the resilient layers. The coil element is positioned within the annular cavity, and compressively enclosed by the resilient layers so as to be partially embedded therein, with the opposite end portions thereof being held in a fluid-tight manner between the resilient layers so as to be isolated from the mold cavity. A molten resin is injected into the mold cavity, and after the resin thus injected has been solidified, the resulting coil device is automatically removed from the mandrel through relative movement of the molds and mandrel.
