摘要： An organopolysiloxane suitable for use in treating paper to be used in plaster boards. The organopolysiloxane is obtained by reacting a polysiloxanol of the formula ##STR1## in which R.sup.1 is a methyl or a phenyl radical, at least 90% of the R.sup.1 radicals however being methyl radicals, andn=20 to 250,with a silane having the formulaH.sub.2 N--R.sup.3 --Si(OR.sup.2).sub.3in whichR.sup.2 is a lower alkyl radical with 1 to 4 carbon atoms,R.sup.3 is a bivalent alkyl radical with 1 to 6 carbon atoms or the --(CH.sub.2).sub.x R.sup.4 (CH.sub.2).sub.y --NH.sub.2 radical, in whichR.sup.4 is oxygen, sulfur or the --NH-- or --NH--CH.sub.2 CH.sub.2 --NH-- radical andx.ltoreq.3, andy.ltoreq.2,in such amounts that 1 SiOH group of the polysiloxanol corresponds to more than 1 and up to 3 OR.sup.2 groups of the silane. Method for preparation of paper and cardboard for use in plaster boards as well as plaster boards made by using the present invention are disclosed.

摘要： The apparatus comprises a mole to be pulled through an existing pipe provided with a cone-shaped head portion for widening an existing pipe, a cutting arrangement with radially protruding blades in front of the effective head portion and a guidance portion having a cylindrical portion centered on the mole axis which precedes the cutting arrangement, the diameter of the cylindrical part being slightly smaller than the bore diameter of the existing pipe. For cutting along two lines parallel to the line of apparatus advance and for centering the apparatus in the existing pipe in the case of any usual utility line, a cable passes axially through the cylindrical portion of the apparatus and is fastened to the head portion of the mole. The guidance portion is loosely attached to the cone-shaped head portion and is axially moved through the existing pipe by the head portion and the cable.

摘要： Use of an organopolysiloxane having the formula ##STR1## in which R.sup.1 is an alkyl or aryl radical, at least 80% of the R.sup.1 radicals being alkyl radicals,R.sup.2 is an alkyl radical or the R.sup.4 Z radical, at least 2/3 of the R.sup.2 radicals being R.sup.4 Z radicals, in whichR.sup.4 is a difunctional hydrocarbon radical,Z is --NH.sub.2, --NH(CH.sub.2).sub.c --NH.sub.2, --NH(CH.sub.2).sub.c NH(CH.sub.2).sub.c NH.sub.2, in which c is 2, 3, --NHCONH.sub.2 radical, --SH, --S.sub.4 --R.sup.4 --Si(OR.sup.3).sub.3, --P(C.sub.6 H.sub.5).sub.2 or ##STR2## R.sup.3 is an alkyl radical with 1 to 4 carbon atoms, or a hydrogen radical,a is not less than 4,b/a is not less than 0.001, but not greater than 0.5, andx is not less than 0.1, but not greater than 2,as a material for decreasing the water absorption of paper which is intended to be used for coating plaster paste in the manufacture of paper-laminated plaster boards. The organosilicon compounds cure without the use of special catalysts. Their aqueous preparations exhibit high stability at use concentrations and are independent of the pH of the paper. The water absorption of papers which are free of aluminum sulfate can also be reduced.
