  • Patent number: 4059136
    Abstract: Thread locking structure in which the separate fluid parts of a two-part adhesive (such as an epoxy resin and an activator) are applied in circumferentially related relation to the threads of a threaded member such as a bolt. At least one pair of adjacent edges of the deposits are in contact and the parts are covered with a single protective sealing film such for example as polyvinyl alcohol. When the companion threaded member is engaged, the two parts of the adhesive are intermingled mechanically and the setting up of the adhesive is initiated.

  • Patent number: 4021591
    Abstract: A dry release sublimation transfer is provided which includes a temporary backing sheet having disposed thereon a sublimation transfer design layer formed of one or more sublimation transfer inks, and a polymeric coating disposed in contact with such design layer. In one embodiment, the design layer is first printed on the backing sheet employing conventional printing techniques and thereafter the polymeric coating is applied over the design layer. In another embodiment, the polymeric coating is first applied to the backing sheet and thereafter the design layer is printed over the polymeric coating. The dry release sublimation transfer is applied under heat and pressure to a substrate to be decorated, such as cotton fabric or a cotton-polyester fabric, thereby causing the polymeric coating to soften and penetrate into the substrate and upon cooling securely bond the design layer to the substrate.

  • Patent number: 3984592
    Abstract: An improved metal foil composite sheet and method of fabricating the same for heating and/or cooling food products. Metal foil is coated on one surface with a heat stable, thermoplastic, epoxy and on its second surface with a heat resistant, dielectric, thermosetting base coat and a top coat of a heat resistant, heat absorptive, thermosetting material. The top coat may be applied in zones of distinct thicknesses simultaneously. Such application provides for legible printing, while preserving the desired heat absorptive properties on the entire foil pouch stock including both the printed and unprinted regions. A completed foil pouch composed of the foil composite sheet permits uniform heating and/or cooling of foods over an extended range of temperatures and times while resisting undesired deterioration.
