Abstract: A room-temperature-curable organopolysiloxane composition for an oil seal, wherein an organosilane compound containing a specific organo-oxymethyl group and represented by formula (1) below and/or a partial hydrolysis condensate of said compound is used as a curing agent (crosslinking agent), and an organic compound having a guanidine skeleton is added in combination as a curing catalyst. In the formula, each R1 is independently a C1-12 unsubstituted or substituted monovalent hydrocarbon group, R2 is a C1-12 unsubstituted or substituted monovalent hydrocarbon group, Y is a hydrolyzable group, and n is 0, 1 or 2.

Abstract: An end fitting for a cable assembly including a conduit and a core wire slidably positioned within the conduit. The fitting includes a housing, an elongated guide member, and a locking clip. The housing includes a rear wall having an aperture, a forward wall having an rear wall aperture axially aligned with the aperture, a lock window positioned between the rear and forward walls, and a forward window spaced forwardly from the lock window. The guide member is secured at its rear end to the core wire and is slidably received at its forward end in the housing apertures. The guide member includes a plurality of axially spaced serrations and a head portion at its forward end which is radially compressible to allow the guide member to be passed through the apertures in the walls whereafter the head member expands to preclude withdrawal of the guide member from the housing.

Abstract: A fuel assembly for a nuclear reactor comprising a fuel cladding tube of three-layer structure having an outer surface in contact with reactor water of the nuclear reactor, an inner surface layer in contact with the nuclear fuel, and an intermediate layer interposed between the outer surface layer and the inner surface layer. the outer surface layer is made of a Zr-based alloy containing Nb, Sn and Mo. The inner surface layer is made of pure zirconium. The intermediate layer is made of a high ductility alloy which is higher in ductility than the outer surface layer and is higher in strength than the inner surface layer.

Abstract: A permselective membrane is obtained by fabricating and crosslinking a methylolated vinylphenol polymer having repeat units having the formula ##STR1## wherein p, q and r are respectively 1 or 2; x and y are respectively selected so as to give a ratio of methylol groups/hydroxy groups of from 0.01 to 2.0; m and n are respectively integers to provide 1.gtoreq.m/m+n.gtoreq.0.2; and X and Y are selected from the group consisting of --R, --Cl, --Br, --CO.sub.2 R, ##STR2## so as to copolymerize a vinyl monomer CH.sub.2 =CXY with a vinylphenol; and R, R' and R" represent hydrogen atom or a C.sub.1 -C.sub.4 alkyl group.
