Abstract: A treating process for the separation of coated nuclear fuel particles from a graphitic matrix in which the nuclear fuel particles are embedded, which is employed in an installation for the conditioning of graphitic fuel elements of high-temperature nuclear reactors. The graphite which encompasses the nuclear fuel particles is conducted away through the action of a brush which isolates the nuclear fuel particles together with their coatings or the nuclear particles themselves, and wherein the nuclear fuel particles which are contained in the brushed product are then separated from the comminuted graphite. The nuclear fuel particles are worked out of the graphitic matrix through the action of the bristles of the brush which conduct the graphite away, but in which the coated nuclear fuel particles when they are contained within hard coatings or the nuclear fuel particles themselves, remain preserved.

Abstract: A treating process is provided for the separation of coated nuclear fuel particles from a graphitic matrix in which the nuclear fuel particles are embedded, and an installation provides for the conditioning of graphitic fuel elements of high-temperature nuclear reactors. The graphite which encompasses the nuclear fuel particles is conducted away through the action of a brush which isolates the nuclear fuel particles together with their coatings or the nuclear particles themselves. The nuclear fuel particles which are contained in the brushed product are then separated from the comminuted graphite.

Abstract: A process for improving the free-flowing qualities of a urea formaldehyde resin which comprises adding to said resin:A. a polyorganosiloxane having recurring units of the formulaX(R).sub.a SiO.sub.3-a/2whereinX is alkyl, alkylene or a hydrocarbon having a functional group;R is hydrogen, alkyl, alkoxy or aryl;a is a value from 0 to 2, or a hydrolysis product thereof;OrB. a silane of the formula Y--A.sub.n --Si(R").sub.b (OR').sub.3-bWhereinY is a substituted or unsubstituted amino, carboxyl, glycidyl, mercapto or alkenyl group;A is a bivalent straight or branched-chained alkylene radical which can contain oxygen in the chain;R' is an alkyl or hydroxyalkyl radical;R" is a C.sub.1 -C.sub.4 alkyl radical;n is 0 or 1; andb is 0, 1 or 2, or a hydrolysis product thereof.
