Abstract: The technical field of the invention is concerned with smoke-generating devices and with powdered materials scattered by dispersion means in order to produce a camouflaging cloud which is effective in the infrared region. The material in accordance with the invention essentially consists of at least one powder having grains provided with a coating which is chemically inert with respect to the grain, which affords resistance to temperatures lower than or equal to the dispersion temperature, and which does not oxidize in free air.

Abstract: A method is provided for making fumed silica aggregate having an average convex perimeter in the range of about 0.12 micron to about 0.6 micron based on the combustion of a mixture of a silicon compound, such as an organosilane, an oxygen containing gas, such as air and a fuel such as hydrogen. The fumed silica aggregate has been found to enhance properties in heat curable filled silicone compositions.

Abstract: Sodium Aluminosilicates (SAMS) are produced by silicate/clay reactions under hydrothermal conditions, the SAMS being characterized by low oil absorption values and high total pore volumes. The SAMS products are useful as coating pigments for paper, paper fillers and paint pigments.

Abstract: A universally applicable SiO.sub.2 -flatting agent is described, which consists of SiO.sub.2, 1 to 25% by weight polyol and optionally 1 to 25% by weight wax. The novel flatting agent is, even after lengthy storage, especially at pressure, still easily dispersible, does not lead to the formation of a hard sediment with non-thixotropic paints and lacquers, and has practically no negative effect on the thixotropic behaviour of paints and lacquers based on thixotropic polyamide-modified alkyd resins. The SiO.sub.2, polyol and wax can be brought together in a variety of ways, e.g. during the micronization of the SiO.sub.2 in a jet-mill or mechanical mill by adding polyol and wax at the same time, by spray-drying a suspension of SiO.sub.2 in an aqueous polyol solution or even before drying by adding polyol during washing or an earlier production step. It is also possible to spray-dry a suspension of SiO.sub.2, wax emulsion and polyol.

Abstract: A method is taught of making a multiple-layer, three-layer shingle, in which a base shingle layer is formed by separating a first shingle layer longitudinally into halves, with adhesive applied longitudinally to the halves of the base shingle layer, and with a second shingle layer then being separated into halves to function as secondary shingle layers that are applied over the adhesive on the base shingle layers, to secure them together, and with a third shingle layer being separated longitudinally into halves and then transversely into segments, with adhesive being applied transversely over granules on the top surface of the secondary shingle layer, with the segments of the third shingle layer forming a top shingle layer, with such segments being selectively applied to yield predetermined design effects. The result is to produce a three-layer laminated shingle, with the layers adhered together with granules on the top surfaces of the layers sandwiched therebetween.

Abstract: This invention relates to a molding material composed of a liquid thermosetting resin composition containing styrene monomer as a cross-linking component thereof and chopped glass fiber strands which can give a large molded product having high impact strength in high productivity and a method for manufacture thereof characterized by using glass fiber strands such that the number of glass filaments used in the glass fiber strands falls in the range of 600 to 1,400 per strand, the amount of a binder deposited on the glass fibers is not less than 1.0% by weight, and the percentage of styrene monomer insoluble binder falls in the range of 40 to 90% by weight.

Abstract: A two-part system and method for increasing the reflex-reflectivity of a substrate is disclosed wherein a first aerosol dispensing means containing a first coating composition capable of forming a base coating on a substrate and a second aerosol dispensing means containing a second coating composition capable of imparting reflex-reflectivity to the base coating is employed. The first coating composition comprises a binder resin and a solvent in which the binder resin is dissolved and the second coating composition contains transparent microspheres having a particle size from about 45 to about 90 microns and a carrier in which the transparent microspheres are dispersible. The substrate is coated first with the first coating composition via aerosol means to form a base coating which is subsequently coated with the second coating to impart reflex-reflectivity to the base coating.
