Abstract: The present invention is a contoured wall and method for creating the contour and appearance of a wall formed from individual assembled units such as stones. The wall is formed from a plurality of mating form liners each having a reciprocal contoured surface to that of the desired stone wall. The wall is formed from hardenable construction material such as concrete poured between two mold members with the form liners attached to at least one of the mold members. Each of the form liners has a lateral relief mold face adapted to provide a molded surface having the contour of a stone wall. Each lateral relief mold face of the form liners has a latticework non-linear mortar-forming interlocking portion surrounding stone-forming recessed portions. The form liners ar positionable in a plurality of arrangements wherein the interlocking portions and recessed portions along the mating edge of each form liner mate along the mating edge of the adjacent form liner to form a continuous lateral relief mold face.

Abstract: Apparatus for forming molded products and providing each product with identifying indicia in sequence during the molding operation using at least two mold parts forming a plurality of molding cavities with an identification forming apparatus as an integral part of each of the cavities, each of the identification forming apparatuses having a plurality of rotatable members, each of which has a plurality of circumferentially spaced apart indicium forming members each of which is different and moving at least one of the rotatable members one increment to the next identifying indicium during each molding cycle.

Abstract: A mold for forming a synthetic resin tray to be used in molding chocolate bars comprises a female mold portion defining a mold cavity and a male mold portion including a skirt projecting into the cavity. A plate is disposed in the male mold portion and engages an inwardly extending lip at the free end of the skirt. The plate is provided on a side facing the mold cavity with an inscription and is pressed against the lip by a pressure block disposed in the male mold portion. The pressure block is shiftable to enable a substitution of another inscription plate. The inscription plate may be provided with a projection on the inscription side for forming an opening or a recess in the injection molded tray.

Abstract: Apparatus for forming a hollow blow-molded container utilizes a mold having at least one wall insert for forming a collapse panel in a container.

Abstract: Apparatus for manufacturing plastic shells having decorative features thereon includes a combination mask and container unit that is joined to a known heated mold to deposit a first semi-cured deposit on the mold from supplies of material in the combination mask and container; the mask is configured to have a plurality of wire reinforced foot portions with seal edges configured to be aligned with the sharp edges of recesses in the mold surface defining the decorative feature; when the combination unit is inverted it casts material only on the recesses to form a semi-fused deposit.

Abstract: Repair plates particularly adapted for mending various surfaces of a vehicle tire in which a plate body is formed from an epoxy casting resin material which is stable at curing temperatures of at least 220 deg. F., and has a face surface having the same configuration as the area of the surface of the tire to be mended, and a perforated aluminum plate imbedded in the rear surface of the plate body.

Abstract: A die for processing a pliable plastic moldable material, particularly a plastic resin, has a cylindrical circular cross sectioned passage provided in the die wall. A marking device for the die comprises a ring body held space-fixed in the cylindrical circular cross sectioned passage of the die and a cylindrical circular cross sectioned central body received rotatable, coaxial, and stepwise lockable in the ring body. Both the front surface of the central body and the ring shaped front surface of the ring body form part of the embossing surfaces of the die. The rotatable front surface of the central body carries an indicating mark, while the space-fixed ring shaped front surface of the ring body adjoining the rotatable front surface of the central body is provided with a number of other marks, which can give the date or dates.

Abstract: A device for changing model plates is used in the manufacture of sand molds for foundry molding machines. The vertical axis of the lifting mechanism intersects both the longitudinal axis of the feed mechanism and the pivot field circle of the rotary conveyor for moving the model plates between lifting and molding sites. Model plates can be changed by the device without interrupting the molding machine cycle. Also, the model plates can be positioned outside the molding machine.

Abstract: There is disclosed a method for imparting a decorative or printed pattern to the surface of rotationally molded products during their manufacture. In this method, the decorative patterns are formed on a sheet film transfer as a coating of pigments dispersed in a hydrocarbon wax which overlays a release agent, such as a silicone coating on the sheet film. The decorative wax pattern is applied to a preselected area of an inside wall of the rotational molding cavity by positioning the transfer against the surface of the wall and burnishing the pattern onto the interior wall of the mold cavity. Thereafter, the particulate molding resin is charged to the cavity and the product is molded in a conventional procedure, resulting in transfer of the pattern as pigments incorporated into the resin, with most of the wax surfacing and being excluded from the product.

Abstract: An apparatus for cutting out and simultaneously decoratively impressing a top crust for a filled pie from a rolled out sheet of dough having a flat annular sturdy plate with an upper side from the center of which a handle projects and with an underside from the circumference of which an annular cutting rim depends. Decorative die elements are removably provided on the underside of the plate within the area circumscribed by the cutting rim and form selected decorative depressions in the pie crust section as it is cut out from a rolled out sheet of dough with the depressions being later filled in with a food coloring filler after the cutout pie crust section is placed over the filling in a pie.

Abstract: An assembly is provided for molding plastic decorations. The assembly includes a support plate for the mold frame and holding fixtures which are positionable to provide a snap-in and snap-out holding relation with the mold frame. The assembly is adapted for use in manufacturing perfume-release plastic decorations which resemble stained glass miniatures.

Abstract: Disclosed is a method and apparatus for forming indicia on the outside of a roto-molded plastic container during the roto-molding process wherein a template bearing a mirror image of the indicia is removably affixed to the interior wall surface of a mold.

Abstract: This invention relates to a novel inlay mold for use with a candle mold as a means for inlaying decorative molded wax inserts into one or more exposed faces of the latter while at the same time fusing them together to produce a unitary structure, such accessory including an open-topped shallow marginally-rimmed reservoir shaped to define a decorative insert into which molten wax is poured and allowed to set; and, hook-forming means for suspending said reservoir thus filled with wax in upright position from the rim of a candle mold flush against the wall thereof facing inwardly.
