Abstract: The invention core member is prepared by treatment of non-woven fabric with a coating composition which comprises an emulsion-form curable vinyl polymer, heat-expandable microspheres, and a thiocyanate compound, and this core member is advantageously utilized with use of liquid-form unsaturated polyester-based molding composition which contains a cobalt-containing compound as cure accelerator, wherein color development becomes available when said unsaturated polyester-based liquid composition infiltrates into voids of the core member, due to encounter of the thiocyanate compound with the cobalt-containing compound, thereby infiltration of said liquid composition is monitored by use of the color development.

Abstract: An object of this invention is to provide a solar heat selective absorbing material of high performance which is prepared by using a diversity substrate by simple manufacturing methods. The construction of the solar heat selective absorbing material is such that a carbide of a transition metal belonging to the IV group of periodic table or a mixed powder of the carbide and the aluminum is applied directly or by means of a binder on the surface of the substrate to form a film. This solar heat selective absorbing material is manufactured by a method of forming a film of material, for example, ZrC on the surface of the substrate by high frequency sputtering or a method of mixing a mixed powder of the ZrC and Al with a resin binder and coating or printing the mixed material on the surface of the substrate.

Abstract: The present invention provides improved elastomeric interference films which are readily coextruded, have improved transparency, and have greater mismatches of refractive indices than those of the prior art. An improved elastomeric optical interference film comprising at least 100 alternating layers of at least first and second divergent substantially transparent elastomeric polymeric materials is provided. Adjacent layers of the first and second polymeric materials differ from each other in refractive index by at least about 0.05, and the thickness of the layers is from about 0.05 to about 0.5 micrometers. Stretching the films results in different wavelengths of light being reflected.

The barrier layer comprises a flame durable fabric substrate formed of fire-resistant fibers.

Abstract: A textured, continuous, multi-filament polyester yarn or fabric has a plasticizer incorporated onto the surface thereof and/or into the interfilamentary structure thereof either during the texturizing process or after the yarn has been made into a gauze-like fabric substrate. Because of the plasticizer, the gauze is enabled to be laminated to a vinyl sheet as it is formed. The plasticizer is characterized in that it is compatible with both the vinyl and the polyester, it softens the vinyl to receive the polyester gauze, it has a viscosity in the range of 25-105 centistokes (cs), and it swells or plasticizes the vinyl to such an extent that the polyester gauze becomes imbedded therein and affixed thereto to effectively bond the gauze to the vinyl. The gauze fabric substrate, when laminated to the vinyl sheet material, gives the vinyl sheet both enhanced strength and stability.

Abstract: A sign is made by a pultrusion process by printing separate sign panels and attaching them to a fibrous component of the sign to make a longitudinally continuous sign panel subassembly which is beneath the surface of the sign. The sign panels are spaced apart in the subassembly by about the length of the sign and are fixed to the fibrous component prior to being pulled through a forming die. In the forming die, the subassembly is formed together with rovings, scrim resin and any other components of the sign into the cross-section of the sign. The sign panel subassembly saturates with the resin so that it blends in with the rest of the sign except for identification matter printed on it and is permeable to allow gases to escape as the resin cures in the die. The sign takes on its desired cross-sectional shape in the die and is cut off at its desired length after it exits the die. The sign panel may be on either side of the subassembly, and the subassembly may be beneath a surface layer.

Abstract: A fumigant applicator for releasing therefrom a volatile substance, e.g., phosphine from a metal phosphide, at a controlled rate, thereby avoiding excessive local phosphine build-up and with complete protection of the contents against liquid water, in the shape of a sachet at least one face of which is formed from a spun-bonded, polyolefin sheet or fleece of heat and pressure bonded polyolefin fibers, which is vapor- and gas-pervious but impervious to liquid water and use, naturally water-resistant and of high tensile and tear strength, which sheet or fleece is rendered heat-weldable and is heat-sealed at its edges by a high porous coating, preferably a powder sprinkle coating, of a thermoplastic heat welding bonding layer which melts lower than the polyolefin fibers so that a heat welding seam at the edges of the sheet can form before the fibers melt so that the physical properties of the polyolefin fibers and the gas permeability thereof are substantially unaffected.

Abstract: Method and apparatus for sealing the end of a thermoplastic tube wherein a tapered mandrel is heated to a temperature above the melting point of the tube and is inserted into the tube to force direct contact of the tube with the mandrel. After the contacted surface has fused, the mandrel is raised and a heated jet of air expands the tube, allowing the mandrel to be withdrawn. Jaws clamp the mandrel surfaces together to form the seal.

Abstract: Filling material for percolating filters for the treatment of liquid and process for producing and assembling the material. Especially in biological sewage treatment, filling material must provide the best possible hold for the biological filter film necessary for the purpose and must have uniform wettability. The disadvantage of known apparatuses meeting these requirements is that they either tend to clog or are difficult to produce. The new filling material will work effectively and reliably, while being simple to produce and assemble. To provide ideal growth surfaces for the biological filter film, the filling material has a plurality of plastic strips (20) which are connected to one another by means of a single holding sheet (21). Furthermore, the strips (20) have a special shape, in particular corrugated edges and/or a structured neutral region. The filling material is especially suitable for biological treatment, particularly the denitrification of sewage or drinking water.

Abstract: Sleeves formed of fabrics comprised wholly or in part from engineered plastic materials which are settable by heat to be biased to a specific sleeve geometry are disclosed. One form of sleeve illustrated involves heat-setting plastic material to a helical configuration by wrapping an elongated strip of the fabric material helically on a mandrel, heating the material while in the helical configuration, and thereafter cooling the material so that is has a permanent helical set with the side edges of the material in overlapping relation. the sleeves so formed may be collapsed into a short cylinder for packaging. In use, the compressed cylinder is allowed to expand lengthwise over an elongate object or objects to effect a jacketing of the same without additional assembly effort. A second form of sleeve disclosed involves setting the fabric material in tubular form, wherein the product is formed to have side edges abutting one another or in overlapping relation.
