  • Patent number: 5118527
    Abstract: A method of packaging dry grout involving a novel aluminum product for use in packaged dry grout. Aluminum flakes conventionally used as an expanding agent in a grout fluidifier are coated with a film which has limited sensitivity to the moisture and the alkali (cement) in dry grout and are then blended with the materials (comprising cement ) to be packaged as a dry grout for mixing with water to form a wet grout. The coating used is highly sensitive to the water and/or alkaline nature of the wet grout and readily deteriorates when the dry grout is mixed with water. A coating and binder, e.g., sodium silicate, may be used to coat the aluminum flakes and to adhere the aluminum to micro-particles, such as glassy microspheres, prior to a dry grout blending operation.

  • Patent number: 5039557
    Abstract: A method and apparatus for applying or re-applying retro-reflective glass beads to in-place thermoplastic pavement marking lines. A heated container warms the beads to a temperature below their melting point but above the melting point of the line. The heated beads are then uniformly dispersed onto the surface of the line. Heat from each bead is thereby transferred into the surrounding thermoplastic material, causing the material to melt and the bead to adhere. The beads are then embedded into the thermoplastic by suitable means such as a roller. By adjusting the temperature of the beads and/or the downward force of the rollers, the depth of the embedded beads can be controlled for optimum reflectivity and adhesion, and variations in ambient operating conditions can be accommodated. The line is usable by traffic essentially immediately after bead application. The same apparatus can be used to apply beads of varying sizes.

  • Patent number: 5015499
    Abstract: Composite or assembled gemstones are usually made by laminating together several layers of rock or mineral substances. Established lapidary processes used in making these stones are very effective when the gem-material part of the composite stone is of stable composition. Such material can then be easily cut and ground into the smooth flat layers necessary for laminating. These same methods, however, prove much less effective when applied to poorly-consolidated gem material: material that because of its friable nature tends to chip and flake when attempts are made to cut it into layers. My process is designed specifically for use on this latter type of gem material and is especially suited to processing gem-quality fossil ammonite shell. This process differs from the traditional methods in that it eliminates the need for cutting and grinding the gem material into smooth, flat layers. Instead, the gem material is simply shredded or fragmented into a mass of small, thin flakes.

  • Patent number: 4879136
    Abstract: A method of building a dental appliance and a kit for use in the method are provided. In the method, metal copings are coated with an opaque ceramic paste, and a coarse ceramic powder, having structural stability under the conditions needed to fire the ceramic paste, is dusted on the coating of ceramic paste, and the coping is fired. A coated metal coping with a rough, sandpaper like surface is produced, and subsequent layers of ceramic paste are applied to the rough surface to build up the dental appliance. The kit of the invention provides at least one preformed opaque ceramic paste, dusting powders, and other ingredients needed to build a dental appliance.

  • Patent number: 4871586
    Abstract: A process for the preparation of an iron armature for use with slabs or reinforced articles consists of making an agglomerate of siliceous sand, marble, granite or, in general, stone with cement as a binder, covering an iron armature rod (1) with the agglomerate to obtain a rod covered with a layer of the agglomerate, immersing said covered rod in a vessel (2) containing a resin (3) so that a film of resin on the covered rod is obtained, spreading on the surface thereof granules of siliceous sand or other stone material (4) so that adherence is achieved between the iron rod and the agglomerate, and resistance to oxidation and improvement in aesthetic properties is achieved. According to one embodiment of the invention, the resin may be sprinkled.

  • Patent number: 4813590
    Abstract: To alter the surface qualities of nonreactive materials, such as polypropylene and polyethylene in order to provide a means for bonding the plastic to metal, hard granular materials of oxides or carbides are partially impregnated into the surface of the plastic by application of heat and pressure so that granular edges remain exposed. Thereafter, a silver coating is applied over the impregnated plastic to interlock with the granules. The composite layered plastic then provides a means for soldering or bonding the plastic to a metallic coupling using either a bonding cement or a low temperature solder such as bismuth, lead, or tin based solder. Abrasion-resistant qualities also are improved by impregnating the internal surfaces of a plastic tube in order to improve its wear-resistance during transporting abrasive slurries of sand, coal, and the like.

  • Patent number: 4788080
    Abstract: There is disclosed a process for coating particles, such as ceramic, metallic and organic cores, with fine powder, such as ceramic, metal, organic or carbon powder. The process comprises providing a mixture comprising the particles and a binder which is capable of slowly melting to viscous state. Then the mixture is tumbled while slowly heating it to enable the binder to reach the viscous state while allowing the particles to be substantially covered with the binder. The next step includes cooling the mixture to about room temperature and thereafter breaking up the particles that may have agglomerated during the tumbling and heating to give individual particles covered with the binder. As a final step, the fine powder is added to the individual binder covered particles and the mixture is tumbled and heated again to the viscous state under conditions effective to provide a coating of the fine powder on the particles.
