Abstract: An in-mold coating composition is disclosed which includes (a) an isocyanate-terminated material containing an excess of reactive isocyanate groups and (b) a material selected from the group consisting of a composition containing reactive hydrogen atoms, generally hydroxyl groups, and a catalyst capable of trimerizing the terminal isocyanate groups. The coating composition is applied to a molded substrate, such as an FRP part, by placing a charge of the composition in the mold on the substrate, the charge being sufficient to provide a coating having a thickness less than about 20 mils. Appropriate pressure is then applied to the charge, such as by closing the mold, so that the coating composition is forced to cover substantially the entire surface area of the substrate, filling any surface defects. The composition is cured to yield a crosslinked, isocyanate-based coating which adheres tightly to the substrate.

Abstract: A method of incorporating a pre-cut foil sheet in a container moulded from a thermoplastic material by injection moulding techniques during the process of moulding the container. The foil sheets are fed singly from a store to a position of registry with the free end of the plunger forming part of the mould of the injection moulding apparatus, whereafter the mould is closed, the foil sheet being wrapped around the plunger upon entry thereof into the die. A moulding compound is then injected into the mould. The stream of moulding compound entering the mould is guided so that the foil sheet is either located on the inner surface of the moulded object or on the outer surface thereof.

Abstract: The invention discloses a process of multi-material moulding using a novel material guidance device or transfer plate which also acts as a transport mechanism to guide, from one moulding station, a partially moulded component or article, along a controlled flow path, to another station and to register the said article into the requisite second cavity thereat for subsequent moulding of another mould material. The transport mechanism, on arrival at the second station, may, but need not, be stripped away from the partially moulded component contained thereon, but only after the article is disposed into the registration within a subsequent or second cavity located at the second mould station. Under the preferred embodiment, the transfer plate acts as a core member to the mould of the cavity during at least one moulding step; in its simplest form the transfer plate is flat.

Abstract: A method of embellishing memorial stones and the like wherein a cavity is cut or sandblasted in the stone to produce a decorative design. An epoxy resin base is inserted into the cavity and permitted to set. Decorative glass chips are arranged in a mosaic-like pattern in a resin of similar properties to the base, the mortar, and a bond is formed between the base resin, the mortar resin, and the decorative chips to provide a pattern on the memorial stone.

Abstract: The invention concerns a process for the manufacture of textile or wire-reinforced hoses, the components of which are placed while the inner tube is supported by a mandrel.According to this invention, the mandrel is made of a congealable fluid which is introduced inside the tube and then cooled and solidified during manufacturing steps wherein the formed assembly will resist mechanical stresses which would not be endured by the sole constituents of the hose. The mandrel is thereafter brought back to a liquid form to be drained off.The invention is applicable to the manufacture of medium and high pressure hoses.

Abstract: This application discloses a method for making a candle with stones, or other desired articles, cast into the candle about the periphery thereof. This is accomplished by the use of a two step casting process, wherein a smaller core of the candle is first cast, and this core is then placed in a larger mold of substantially identical shape. The stones or other articles are then placed in the larger mold between the smaller core and the inner wall of said mold until the space therein is completely filled. Wax is then poured into the larger mold to cast these articles into the surface of the candle. Since the wax at this point will almost completely cover the articles, which are of a decorative nature and of which more of the surface should be exposed, the candle, after it has cooled, is repeatedly dipped in hot wax to remove some of the surface wax from the candle with each dipping, and then cooled by dipping the candle in water.

Abstract: A method for producing glass fiber reinforced plastic molded articles with decorative patterns thereon is provided, which method includes the steps of placing at least two kinds of differently colored sheet molding compound (SMC) mat layers on a stationary mold, each of the SMC mats including glass fibers impregnated with resin, the resin in each of the SMC mats including different colorants, the area of each SMC mat layer occupying less than the total effective molding surface area of the stationary mold surface, disposing a movable mold in engagement with the stationary mold with the SMC mat layers interposed between such molds, and applying heat and pressure to the molds so as to fluidize and polymerize and cure the resin in the SMC mats. When fluidized, the two kinds of differently colored mats are mingled with each other to form flow patterns comprised of the distinct colors of each of the mats.
