Abstract: A process for producing feldspathic sanitary ware and the end product are disclosed in which a fluxing amount of a glass frit is used in the ceramic slip used to cast the sanitary ware. The frit contains both deflocculent oxides and flocculent alkaline earths which are leachable from the frit when it is placed in the ceramic slip. The deflocculent oxides counterbalance the effect of the flocculent alkaline earths to the extent they are respectively leached from the frit upon dispersal in a ceramic slip and maintain the slip at a workable viscosity. Upon casting and firing the slip, the present frit precipitates fine crystals of diopside having an average particle size of less than one micron which are particularly useful in lowering the firing temperature of feldspathic bodies by promoting the required degree of vitrification at lower temperatures than heretofore possible.

Abstract: There is disclosed a process for producing a tri-halogenated polystyrene flame retardant for synthetic resins, whereby high molecular weight polystyrene is reacted with bromine chloride in a chlorinated hydrocarbon solvent, under substantially anhydrous conditions, in the presence of a catalytic amount of a Lewis acid.

Abstract: A molding process, resinous formulations for use in the process, and the resulting products are disclosed characterized in that the product comprises mainly a bulk or fill resinous body having a film or skin of a cross-linked polyester resin formed about the body. Even though the body has intricate curving surface contours, the film is smooth and free of surface tears and blemishes. The product is molded by first spraying formulated, dry particles of a partially cured polyester resin against a hot mold to cause the particles to fuse and flow and form a substantially continuous skin or film on the mold. Thereafter, the bulk resin is added and the mold is heated to cure the polyester resin as well as the bulk resin and to interreact the bulk and polyester resins together to mold the bulk resin with a film of the polyester resin.

Abstract: There is provided a metallurgical well powder having reduced tendencies to hinder the flow of molten metal, by packing and jamming the opening, in a steel ladle for example, through which said molten metal will be teemed upon tapping said ladle.

Abstract: A moldable sound control composite is disclosed combining in itself when molded damping, barrier performance, and structural strength for use within a predetermined environment temperature range. As such, the moldable composite is not applied to other structures to damp their sound generation, but forms by itself a complete structural member having not only desirable sound reducing properties but desirable strength properties as well. The composite comprises a blend of a primary non-viscoelastic organic polymeric resinuous material intended to impart structural strength to the composite, a secondary viscoelastic organic polymeric resinuous material to provide damping performance, and filler material adapted to densify the composite and impart barrier performance. Optionally, at least one of the primary and secondary resinuous materials may be thermosetting.

Abstract: A reflective sheeting is disclosed having spaced apart cavities extending along one face and light-reflecting beads lining both wall and bottom portions of the cavities to impart a wide angle retroreflective response to incident light and improved brightness or intensity. The sheet is prepared by forming in a deformable carrier sheet a network of relatively depressed cavities having wall and bottom portions and spaced apart by intervening ridges, and then coating the wall and bottom portions of the cavities and the ridges with light-reflecting beads. After filling the cavities and covering the ridges with a solidified layer of a resinous organic matrix having a greater adherence to the beads than the carrier sheet has, the sheet is stripped away. This transfers the beads to the organic matrix and locates them in similarly shaped cavities and ridges molded in the matrix by the carrier sheet.

Abstract: An insulating hot topping material including a refractory filler material, an optional light weight insulating filler material and a finely divided particulate carbonaceous material. Dust inhibitors may also be included in the form of a liquid hydrocarbon and/or a fiber material.

Abstract: A retroreflective marking material is disclosed comprising a sheet having at least some light-transmitting portions, a light-refracting surface on one side, and a plurality of trihedral light-reflecting units of three mutually perpendicular facets on the other side adapted to be adhered to a working site. The light-reflecting units are oriented to reflect light having relatively high angles of incidence with respect to the sheet. The marking material may be used as a tape for marking roads and is effective whether wet or dry. Optionally, the sheet or tape has light-receptors which rise above the tape and are spaced apart along one direction of the tape, and the trihedral light-reflecting units are substantially opposite the light-receptors. Preferably, the light-reflecting units have the shape of a triangular-based pyramid, and the marking material retroreflects the light in two opposite directions.

Abstract: A process is disclosed for molding a mixture of refractory particles, and especially abrasive refractory particles, and an organic resinous binder into an integral body. The mixture is preheated, preferably by microwave energy, in the absence of pressure on the mixture to a temperature elevated with respect to room temperature to insure the binder is fluid but below a temperature at which degradation or decomposition of the binder takes place. The mixture is then compacted by pressure, preferably at the preheating temperature, until a density is reached substantially equal to that desired in the finally molded integral body while still maintaining the binder in a fluid state. The resinous binder is then converted to a solid state to bind the particles one to another while still maintaining the compaction pressure on the mixture.

Abstract: A bag-like shroud is provided for a garment trolley bar for the purpose of both protecting, and preventing displacement in transit of, hanger-hung garments carried by said trolley bar.

Abstract: A process and resulting product are disclosed characterized by superimposing two layers of essentially dry, differing frit compositions onto a substrate and then firing only once to form a dual coat coherent ceramic layer. The composition of the two frits is such that the first or base coat fuses and stabilizes during the firing operation at temperatures below that at which the second or cover coat fuses and stabilizes. Desirably, the first layer forms an amorphous glass adherent to the substrate that is predominantly an alkaline oxide borosilicate glass and preferably an alkaline borofluorosilicate glass.
