Abstract: Microspheres are produced by cobalt gamma radiation initiated polymerization of a dilute aqueous vinyl pyridine solution. Addition of cross-linking agent provides higher surface area beads. Addition of monomers such as hydroxyethylmethacrylate acrylamide or methacrylamide increases hydrophilic properties and surface area of the beads. High surface area catalytic supports are formed in the presence of controlled pore glass substrate.

Abstract: Disclosed is a method for making camouflage from sheets of multi-colored coated fabric. The coated fabric is formed by sandwiching the base fabric between two films of fused polyvinyl chloride film; the two films are tightly bonded to the base fabric. Each film is formed by applying the different - colored plastisols to preselected portions of a carrier web, and then overcoating these colored portions of the web and any uncoated portions of the web with a plastisol of another color. After each of the two multi-colored films is created, they are bonded to the base fabric while the films are still attached to the carrier web; then each carrier web is stripped from the outsides of the finished multi-colored, coated fabric. These multi-colored coated fabrics are cut into sheets which are attached to a net to make the camouflage screen.

Abstract: A pressure-sensitive device is proposed which includes an electrically conducting element in the form of a loop, a screen arranged outwardly of the loop, and a resiliently compressible, non-conducting material between the screen and element, the arrangement being such that, on the application of a loading to the screen, the electrical inductance of the loop is changed, such change being sensed by a reactance-dependent detecting circuit (DET) connected therewith.

Abstract: This is a decorative linkwork or mesh of interlinked parts which form a sheet for use as a decorative fabric. The linkwork is formed of small overlapping plates and interconnecting rings. Each plate has four outwardly extending arms which are formed into U-shaped hooks for engaging a respective connecting ring. At least one of the outwardly extending arms is relatively longer than the others and has a predetermined portion of its length folded back flat against the plate, resulting in a spacing between the edge of the plate and the beginning of the U-shaped hook formation of that arm.

Abstract: A curl resistant transmissively readable photoplastic film is produced having a base ply of polyethylene terephthalate to one side of which is laminated, in sequence, a light transmissive layer of electrically conductive particles, a primer layer of a dimethyl-phenylene oxide polymer, and a photoplastic layer. The latter layer may be formed from a mixture of 75% by weight of an intermediate molecular weight (800-5,000) polystyrene and 25% by weight of a polymolecular plasticizer derived from alpha-methylstyrene to which mixture has been added about 3.3% of the total weight of solids of very fine particle size copper phthalocyanine. To the other side of the base ply is laminated a layer of a solvent deposited methyl methacrylate polymer. When the photoplastic layer is about 17 to 18 microns thick the methyl methacrylate layer may be about 4 to 6 microns thick.

Abstract: The proposed polycrystalline superhard material comprises sintered particles of cubic boron nitride coated over the whole surface thereof with a layer of a crystalline compound of the chemical formula B.sub.x N.sub.y C.sub.z, where x, y and z can assume any value from 0 to 1, said compound binding together the particles of the cubic boron nitride.According to the present invention the proposed material is produced in the following way: particles of cubic boron nitride are placed in a flow of a gas containing carbon for a carbon layer 1-100 A thick to be built up on the whole surface of said particles.
