Abstract: A method for hydrosilylating a vinyl-substituted aromatic compound comprising reacting a hydrido (hydrocarbonoxy)silane compound with the vinyl-substituted aromatic compound in the presence of a platinum or platinum compound catalyst and a carboxylic acid. The presence of the carboxylic acid increases the positional selectivity of addition in the hydrosilylation reaction and reduces the polymerization of vinyl groups even in the case of a high-temperature or long-term hydrosilylation reaction.

Abstract: A process for manufacturing high molecular weight, alternating polysiloxane copolymers, by solid-liquid phase, nonaqueous, interfacial polymerization. The copolymers consist of alternating siloxane repeating units of the (AB).sub.m type, such as diphenylsiloxane units and dimethylsiloxane units, alternately polymerized together to form the copolymer. The solid-liquid phase interfacial polymerization process is fast, proceeds smoothly at room temperature, and is not reversible, i.e., no cyclic siloxane species are generated. The resulting polysiloxanes can be formed into thermoplastic elastomers which are suitable for use as sealants, fillers, and films.

Coating material (A) comprises finely divided silica and a resin of the formula RSiO.sub.3/2, wherein not less than 1 mol % and not more than 80 mol % of the R groups are fluorohydrocarbon groups of 3 to 12 carbon atoms.

Abstract: An interference filter (10, 30, 50, 70, 90, 110, 130, 150, or 190) filters selected wavelengths by dividing an input beam into two or more intermediate beams having different optical path lengths and by recombining the intermediate beams into an output beam that is modified by interference between the intermediate beams. An optical path length difference generator (20, 40, 60, 80, 100, 120, 140, 160, or 200) varies the optical path lengths of the intermediate beams by changing the physical lengths of their paths or the refractive indices of the mediums in which they are conveyed. The optical path length generator (20) of one exemplary embodiment (10) includes a spacer plate (20) that is divided into elements (22 and 24) having different refractive indices for varying the optical path lengths of the intermediate beams.

Abstract: A guide eye for use with a traverse mechanism of a strand package winder is positioned with respect to the surface of the package during the package build process so that the guide eye contacts the package surface in the larger diameter, end regions of the package. This positioning provides a minimal free length between the point at which the strands leaves the guide and the point at which the strand contacts the package surface, giving better control over the placement of the strand onto the package surface, particularly in the end portions of the package. Further, the guide eye is pressed against the package surface, slightly compressing the surface and pressing a portion of the preceding stand courses against the package. This pressure helps to fix the strand in the position in which it was laid down to reduce displacement of the strand course during the package build process.

Abstract: An apparatus for moving a carriage along a roof structure of the type having a plurality of purlins spaced apart from one another in a parallel arrangement, and method of using same are disclosed. The apparatus includes a grappling member mounted for movement along the length of a first one of the plurality of purlins. The grappling member is adapted to be temporarily placed into a locked position so that the grappling member is fixed with respect to the first purlin. A tension member operatively connects the grappling member to the carriage. A pulling device is used to pull on the tension member so as to shorten the distance between the grappling member and the carriage, thereby advancing the carriage along the length of the purlins in a direction towards the grappling member when the grappling member is in the locked position.
