Abstract: A curable resin composition comprising (a) an acrylic, polyester, epoxy or polyol resin having a plurality of alkynyl groups, (b) an organohydrogenpolysiloxane, and (c) an amount of platinum catalyst effective to catalyze the crosslink reaction between (a) and (b). The composition is useful for coating and molding purposes and gives a cured product having excellent acid resistance, water resistance and other properties.

Abstract: Hydrogenpolysiloxanes having a (meth)acryloxypropyl group on a side chain are useful intermediates. They are prepared by equilibration reaction of siloxane compounds.

Abstract: Organopolysiloxanes having two different functional groups selected from the group consisting of 3-glycidoxy-propyl, 2-(3',4'-epoxycyclohexyl)ethyl, 3-hydroxypropyl, 3-(2'-hydroxyethoxy)propyl, 3-acryloxypropyl, and 3-methacryloxypropyl groups are more compatible with organic resins and more effective for tailoring the organic resins. They are produced by hydrosilylation of organohydrogenpolysiloxanes with functional group-containing alkenes.

Abstract: This invention discloses a curing resin composition comprising (a) an organic resin containing no less than 2 alkenyl groups per molecule, and having a number average molecular weight of 500-100,000. (b) an organohydrogen-polysiloxane containing no less than 2 Si--H bonds per molecule, and (c) a platinum catalyst. It is desired that the organic resin of component (a) is at least one type chosen from acrylic, polyester and epoxy. The preferable amount of component (b) is such that there are 0.8-4 hydrogen atoms bonded to silicon atoms per alkenyl group of component (a).

Abstract: In a method and an apparatus for producing a solid-liquid metal mixture in which non-dendritic primary solid particles are dispersed into the remaining liquid matrix through electromagnetic induction system, a core member is arranged inside a cooling agitation tank provided with an electromagnetic induction coil therearound.

Abstract: According to one embodiment of the present invention, the oxygen gas is introduced into a horizontal, unitary and totally-closed furnace shell, and nuclear fuel to be reprocessed is charged onto an oxidation and separation plate which is horizontally disposed for vibration within the furnace shell along the axis, so that the nuclear fuel may be reprocessed by oxidation in the oxygen atmosphere while the fuel is vibrated and transported on the oxidation and separation plate and the reprocessed nuclear fuel in the form of particles may be discharged. At the same time released volatile fission products from the pulverized fuel are isolated by means of a vacuum blower. According to another embodiment of the present invention, a reduction furnace which is substantially similar in construction to the oxidation furnace described above except that a reducing gas is supplied by an independent source.
