Abstract: To manufacture airbags comprising a contact fabric and/or a filter fabric it is proposed to use hollow fiber synthetic filament yarns having a hollow area fraction of 10-40%, based on the total cross-sectional area of the fiber. The closeness values are >72% for the contact fabric and 45-68% for the filter fabric. In addition to reducing the production costs, hollow fibers also make it possible to produce lighter fabrics. These have a beneficial effect on the working of an airbag.

Abstract: A transfer sheet is provided having a substrate coated with pressure-rupturable microcapsules containing an oil and an oil-soluble dye intermediate and a particulate oil-absorptive material which is non-reactive with the dye intermediate and is situated with respect to said microcapsules such that oil released by the microcapsules is absorbed thereby. The concentration of oil absorptive material is sufficient to permit writing on the coated substrate without interference from oil released by ruptured microcapsules but less than that which materially reduces the transfer of oily solution from ruptured microcapsules to an underlying copy sheet.

Abstract: A process for reinforcing or sealing solid structures or for anchoring bolts using macrocapsules which contain at least one part of a multi-part curable polymer system and which fracture under pressure to produce flake-like fragments that aid in mixing the components of the multi-part curable polymer system. The macrocapsules can be conveniently made a part of a sealing cartridge for ease of use.

Abstract: This invention relates to a leader or trailer for a magnetic tape, which comprises a plastic support member, a coated layer consisting essentially of a pigment and binder on the surface of the plastic support and a lubricant layer on the back side of the plastic support, the pigment consisting of a mixture of at least two solid powders each having a mean grain size of (A) 0.002 to 3 microns and (B) 5 to 35 microns and the lubricant layer being coated in a proportion of at least 0.1 mg/m.sup.2.

Abstract: In manufacturing industrial products such as automobiles, it is known to adhere rigid solid objects such as emblems, the manufacturer's name, body trim, and so forth to the automobile body by means of a relatively thick sheet of resilient foamed plastic such as polyurethane, for example, 30 one thousands of an inch (30 mils) in thickness, coated on each face with a pressure sensitive adhesive. This provides a cushioning effect to take care of the wide variations in the uniformity of the emblems and further provides a cushion so that when the emblem is struck a blow it does not pop off as would be the case with a thin adhesive layer absent the foam layer.

Abstract: A base sheet for printing with reactive dyes is provided which has applied on at least one of its surfaces a reactive pigment coating which contains as pigment a mixture of a highly absorbent pigment and a sparingly absorbent pigment and which contains as binder an intimate mixture of a binder which is readily soluble in alcohols with a binder which is resistant to solvents. The base sheet is used as receptive sheet especially in transfer printing processes and permits technically improved operation with reactive dyes.

F in laminates and comprise an ethylene/vinyl acetate copolymer having a vinyl acetate content in the range of 40% to 60%, the copolymer being partially hydrolyzed to form a terpolymer having a hydroxyl content in the range of 1% to 6%, the terpolymer in film form and/or laminate being heat treated and cross-linked to give the adhesive film. The laminates are made from transparent layers of glass and/or plastic bound together with the transparent adhesive film.
