Abstract: Apparatus and process for hot-stamping molded plastic containers in which the container is moved past a heated die having a platen with a printing die, the die being universally movable so that linear uniform pressure is exerted between a confronting container surface and die surface. As the container moves across the die surface, it is rotated so that foil which is pinched between the container and die is transferred onto the surface of the rotatable container. The uniform linear pressure between container and die, transfers foil to the accompaniment of rotation of the container so that defect-free lamination of foil is transferred onto the container surface to form decorative or alpha numeric information. The operation is continuous, with successively spaced containers moving into printing position relatively to the die, where the hot-stamping operation is repeated. Containers are automatically removed after printing, and successive containers supplied either manually or automatically.

Abstract: Honeycomb structures, such as those used in turbine engine abradable seals, are provided with a uniform density filling of a suitable abradable material. The abradable material is prepared as a tape preform using an organic binder. The preform is forced into the honeycomb using a rubber tool.

Abstract: A release film is coated with a thin layer of metal by, for example, a vapor deposition process. The film is then stretched over a composite object, made, e.g., of fiberglass-epoxy or graphite-epoxy, which one desires to metallize. A treatment involving either vacuum or pressure and that may involve heat is used to transfer the thin metal layer to the composite object. The stretchable film is then peeled off the object, leaving a metal coating bonded to the object. The epoxy resin or other adhesive in the composite material gives structural integrity to the object as well as provides a bond for the metal, so that the composite object may be molded and metallized in one step. Alternatively, a two-step process of molding then metallizing or metallizing then molding can be employed.

Abstract: An article-holding turret which is particularly suitable for rotatably conveying large objects. A friction brake is fixed to a pawl plate, and these axially mounted structures are oscillated by a rack and pinion assembly driven from a turret index shuttle. A ratchet and spindle assembly is coaxially mounted on the turret's central shaft, and caused to periodically index through desired angular intervals by a pawl carried on the pawl plate. The forward rotation of the ratchet and spindle assembly is accompanied by a commensurate rotation of the friction brake, thereby minimizing rotational drive forces required during this segment. An auxiliary pawl and bracket assembly prevents retrogression of the ratchet and spindle during the reverse oscillation of the friction brake assembly.
