  • Patent number: 5397620
    Abstract: A structure and related method for forming a surface on which sports activities occur. The disclosed structure uses three basic layers to form the surface on top of a prepared substrate. The first layer is comprised of a plurality of sublayers bound together by adhesive coatings, the first of which requires deposition of resilient particles in the 3 to 6 millimeter size range. Several subsequent sublayers include smaller-sized particles which, after deposition and spreading, result in a relatively smooth and resilient latex-bound base mat. The second layer provides a cushion coating, while a slightly textured decorative finish coating results from application of the third and final top layer. A method for forming these three layers is also disclosed which method specifies both the sizes of particles and the spread rate for particles and adhesive material for each of the sublayers in the first layer.

  • Patent number: 5281507
    Abstract: The present invention resides in a method for transferring images from an image-bearing surface, to a moving web or sheet. The image-bearing surface is advanced in a predetermined direction, and the receptor area of the image-bearing surface is exposed to successive images. The successive images are developed using a liquid toner comprising charged pigmented particles, in a liquid hydrocarbon carrier. A porous web is transported in synchronism with movement of said image-bearing surface into position for transfer of said developed images on said receptor area successively onto said web. In one embodiment, the web is an uncoated, non-conductive porous material. The web is treated with a fluorinated or partially fluorinated hydrocarbon surfactant hold-out material in an amount effective to reduce the penetration rate of the toner carrier into the web so as to ensure that sufficient carrier is available for complete and void-free transfer.

    Abstract: A laminate cover for sealing an opening in a weatherproof roofing membrane includes a top sheet of a weather resistant material, preferably an uncured butyl rubber EPDM material, and a complementary shaped and sized lower sheet of a lightly cured butyl rubber having opposed tacky surfaces. A layer of a flowable sealing material such as an uncured butyl rubber sealing compound having a smaller dimension than that of the lower sheet, is trapped between the lower sheet and a bottom release coated carrier. Upon removal of the carrier, the cover is pressed over the opening to be sealed and an exposed peripheral tacky area of the lower sheet secures the cover to the membrane and traps the sealing compound therein. Applied or ambient heat will cause the sealing compound to flow into the opening to effectively seal the same, and will vulcanize the top sheet to provide abrasion and weather resistance for the cover.

  • Patent number: 5055327
    Abstract: A cast simulated-stone containing flattened globules of overfilled, cured resin, which flattened globules substitute for natural stone chip additives and other such additives. The globules are formed by mixing an excess of a filler with a catalyzed liquid resin composition, the filler being added in an amount sufficient to cause the liquid to break apart into discrete, separable globules of resin composition. The globules are combined with a liquid resin composition and compressed and flattened in forming the simulated-stone.

  • Patent number: 5026590
    Abstract: A transfer recording medium comprising a substrate and a plurality of image forming elements bonded thereto by a binder is provided. The surface of each image forming element at least partially protrudes out of the binder. Such transfer recording medium may be prepared by applying the binder onto the substrate in a prescribed thickness, disposing the image forming elements in excess on the binder, and then removing the excess of the image forming elements. The thus prepared transfer recording medium provides an image having a high density and a faithfully reproducible color.

  • Patent number: 5024126
    Abstract: A process is disclosed for producing a coarse surface on a plastic article, comprising preparing a dispersion of fine crystalline material in a solution of a polymer from which the plastic article is made. The article is immersed into the dispersion, causing a partial solvation and softening of the surface layer coated by the dispersion. Upon removal of the solvent component of the dispersion from the article surface, the fine crystalline material is embedded into the surface of the article so as to create a textured surface suitable for gripping and the like.

  • Patent number: 5015516
    Abstract: The invention provides decorative, inlaid sheet materials which incorporate a matrix layer of discreet, low aspect ratio resinous particles embedded in a resinous coating. The use of printed patterns which are visible beneath the adhesive matrix containing the particles constitutes a preferred embodiment of the invention. The sheet materials of this invention are real through-patterned inlaids which no not lose their pattern due to wear in use, and which offer unique design advantages and flexibility, as well as superior properties.

  • Patent number: 4997735
    Abstract: A process of contacting two photographic elements by juxtaposing the elements and drawing a vacuum between them is described wherein at least one of the elements has been exposed and processed and comprises a support having thereon, as the outermost layer facing the other element, a matte layer comprising matte particles and a polymeric binder. This process is improved by utilizing as the matte layer a layer comprising less than about 1.08 g/m.sup.2 of binder and having matte particles that are present in an amount sufficient and have a mean diameter great enough so that the outermost layer has a roughness measurement, R.sub.a as defined by ANSI Standard B46.1 1985, of greater than about 1.00 microinches.

  • Patent number: 4969251
    Abstract: Pre-glued, coil-coated brake shoe stock is manufactured on a continuous coil coating line wherein a heavy gauge steel strip is continuously fed through abrasion and surface cleaning steps, optionally treated with a phosphoric acid/alcohol solution and then followed by application of a phenol-formaldehyde resin, a controlled curing step, and again coiled. The phenol-formaldehyde resin may have incorporated in it solid particles which will improve the dimensional stability, thermal properties and vibration and sound-dampening characteristics of the brake shoes. Brake shoes stamped from the stock made under the particular conditions described have higher shear strength and adhesion to the brake pad or lining materials than those of the prior art and have fewer problems in manufacturing.

  • Patent number: 4957801
    Abstract: The invention relates to prepregs of fiber-reinforced thermosetting resin that have a coating comprising thermoplastic particles on one or both outer surfaces. Upon lamination of the prepregs into a composite, the layer comprising thermoplastic particles at the surface of the prepreg is formed into a discrete resin layer in the composite at the interface between fiber-reinforced thermosetting resin layers. The laminated composite materials have improved toughness and impact strength due to the thermoplastic particulate material at the interface and yet the composites still retain desired mechanical properties under hot/wet conditions.
