Abstract: A drape interface structure including a rigid frame defining an opening, a membrane spanning the opening of the frame, and a drive transfer element attached to the membrane and adapted to convey motion through the membrane. The membrane includes a first region of a first elastic deformability and a second region of a second elastic deformability different from the first elastic deformability.

Abstract: Optical lenses and associated luminaire are described herein. In one aspect, a lens comprises a light receiving side comprising grooves for receiving light emitting diodes, the grooves defined by a central refractive region and walls comprising total internal reflection faces; and a light extraction side opposite the light receiving side, the light extraction side comprising refractive extraction surfaces, total internal reflection extraction surfaces, or combinations thereof. In some embodiments, luminaire comprises an array of light emitting diodes; and the lens positioned over the array of light emitting diodes.

Abstract: The present invention relates to a process for preparing silylated polyurethane polymers which have increased stability under ambient condition or storage toward atmospheric moisture, in the presence of at least one of titanium-containing catalyst or zirconium-containing catalyst and to silylated polyurethane polymer compositions comprising these catalysts.

Abstract: The present invention relates to dual curing compositions, which cure with moisture and photo radiation, such as UV light, and methods for preparing and using same. In particular, the compositions of the present invention contain a polyether or polyester backbone, photocurable portion(s) and moisture curable portion(s). The photo curable portion is a urethane or carbamate linkage terminated with a (meth)acryloxyalkyl group. The moisture curable portion is either: (1) a portion terminated with a polyalkoxysilyl group; or (2) a portion having a urea linkage terminated with an alkylpolyalkoxysilyl group.

Abstract: A room temperature vulcanizing silicone polymer composition including: a) as part of the silicone polymer, a segment including a silicone polymer of Formula (I): b) a finely-divided inorganic filler present in an amount of at least about 25% by weight of the total composition. Enhanced elongation ability is possessed by these compositions.

Abstract: The present invention concerns ?-silyl terminated polydiorganosiloxanes, a method of making the ?-silyl terminated polydiorganosiloxanes, and sealant compositions containing said compounds and a method of using such sealant compositions.

Abstract: A two-part curable foaming composition comprising: (A) A first part comprising: (i) an alkoxysilyl capped prepolymer; and (ii) a polyhydrogen siloxane; (iii) optionally a catalyst which accelerates both foaming and cross-linking through said alkoxysilyl groups; and (B) A second part comprising: (i) a nitrogen-containing compound having an active hydrogen; (ii) water; and (iii) optionally a catalyst which accelerates both foaming and cross-linking through said alkoxysilyl groups; provided that at least one of the parts contain a catalyst and wherein after mixing together the first and second parts a cured elastomeric foam is formed.
