Abstract: A method is provided for application of a layer permanently adhering to the inside of a breast prosthesis formed as a shell-shaped body made from a soft-elastic material, in which a two-component silicone rubber forming the adhesive layer is injected into a mold prior to curing of the body and then cured together with the body. Alternatively, the two-component silicone rubber forming the adhesive layer is first cured in a shell, with the shell then being applied to the body in a mold and then cured again with the body. In a third alternative, the adhesive layer is cured while being joined to a carrier film, with the carrier film then being adhered to the prosthesis sheath which is then filled with addition-vulcanizing two-component silicone rubber and cured in a mold.

Abstract: A reel or spool package has opposing sidewalls or flanges formed of the specified or appropriate substrate and connected by a core formed of a flowable material which sets or cures to harden, such as a two part expandable polyurethane foam. The foam is applied into a partition, which may be a paper ring, by an injection and metering device. The chemistry of the flowable material may be altered to change density, rigidity and flexibility as required by package stresses. The polyurethane foam is an effective adhesive medium, thereby forming the core and connecting the sidewalls to form the package.

Abstract: A helical antenna having an antenna element covered with an insulating layer is formed by monolithically form the insulating layer so that the antenna element is integrated with the insulating layer. To be more precise, first, a cylindrical shell, which received a core pin in its center hole, is inserted into the antenna element along the longitudinal axis of the antenna element. The antenna element is put in a cavity of a molding die. A moulding resin which was heated and molten at a temperature higher than the melting point of the cylindrical shell is injected into the cavity to form an insulating cover over the cylindrical shell and the antenna element. The surface of the cylindrical shell starts softening upon contacting with the molten resin, and sticks around the helically coiled antenna line, whereby the pitch of the antenna element can be maintained substantially constant even if an injection pressure is applied during the molding.

Abstract: A method of compression moulding an article from rubber moulding material incorporating hollow inserts avoids damage to the inserts. Where compression moulding takes place in an enclosed mould at an elevated pressure, the pressure can distort and damage the hollow inserts especially if they are of plastics. In order to avoid such distortion and damage, the method compresses during moulding creating a pressure in a cavity of the insert which substantially balances the pressure exerted on the exterior of the insert by the rubber moulding material in the mould. The pressure in the cavity is preferably produced by introducing some rubber moulding material into the cavity of the insert. This material becomes pressurized during moulding and supports the interior of the insert.

Abstract: In the method, after the pattern-bearing film is fed to the female mold, the distal end of the film is fixed under a lower portion of the female mold, and at the same time the film is retreated by a force from the film supply portion. Thus, this tightens up the film so that the slacks or wrinkles cannot be formed on the film. Therefore, the film can be fortunately spread around the parting surface of the female mold. In the apparatus, the film suppressing frame is pressed to the female mold through the sliding rod arranged in the female mold, in such a manner that the female mold embraces the frame. Thus, the pressing of the frame is performed by a simple structure, and the film is accurately positioned to the internal surface of the female mold. Also, the film suppressing frame is constituted to advance from and retreat to the female mold. Thus, this causes a space between the both molds and an outside standby position to be useless. A space around the apparatus can be effectively utilized.

Abstract: A method of compression moulding an article from rubber moulding material incorporating hollow inserts avoids damage to the inserts. Where compression moulding takes place in an enclosed mould at an elevated pressure, the pressure can distort and damage the hollow inserts especially if they are of plastics. In order to avoid such distortion and damage, the method compresses during moulding creating a pressure in a cavity of the insert which substantially balances the pressure exerted on the exterior of the insert by the rubber moulding material in the mould. The pressure in the cavity is preferably produced by introducing some rubber moulding material into the cavity of the insert. This material becomes pressurised during moulding and supports the interior of the insert.
