    摘要： Sequentially applying two different coatings, in two steps, to metallic surfaces. Metallic surfaces are contacted at temperatures from 10-100° C. with aqueous solution A and then with aqueous solution B, or vice versa, wherein solution A contains an effective amount of zirconium, hafnium, titanium, silicon and/or boron, and of fluoride as ions and/or complex ions able to pickle metallic surfaces and generate a coating on the pickled metallic surface and that solution B contains an effective amount of one or more of XYZ, X*Y*Z* and/or X*Y*Z*Y*X* where Y is an organic group with 2-50 carbons, where X as well as Z is a group—each same or different—of OH—, SH—, NH2—, NHR—, CN—, CH═CH2—, OCN—, CONHOH—, COOR′, acrylamide-, epoxide-, CH2═CR″—COO—, COOH—, HSO3—, HSO4—, (OH)2PO—, (OH)2PO2—, (OH)(OR′)PO—, (OH)(OR′)PO2—, SiH3—, Si(OH)3—, where R′ is an alkyl group with 1-4 carbons, where R″ is hydrogen or an alkyl group with 1-4 carbons, and where X and Z are each bound to the Y in their terminal position, where Y* is an organic group with 1-30 carbons, where X* as well as Z* is a group—each same or different—of OH—, SH—, NH2—, NHR′—, CN—, CH═CH2—, OCN—, CONHOH—, COOR′, acrylamide-, epoxide-, CH2═CR″—COO—, COOH—, HSO3—, HSO4—, (OH)2PO—, (OH)2PO2—, (OH)(OR′)PO—, (OH)(OR′)PO2—, SiH3—, Si(OH)3—,N—CH2—PO(OH)2—, —N—[CH2—PO(OH)2]2— where R′ is an alkyl group with 1-4 carbons, where R″is hydrogen or an alkyl group with 1-4 carbons.

    摘要： Bead-form expandable styrene polymers are obtained by suspension polymerization of styrene with addition of from 1 to 10% by weight of C.sub.3 - to C.sub.7 -hydrocarbons and/or carbon dioxide as blowing agent and, if desired, conventional additives, using, as suspension stabilizer, a mixture of magnesium pyrophosphate, a sulfonate group-containing extender and an alkali metal carboxylate or alkaline earth metal carboxylate, the magnesium pyrophosphate being prepared immediately before the polymerization by combining an aqueous solution of alkali metal pyrophosphate with at least the stoichiometrically necessary amount of a magnesium salt.

    摘要： Knitting machine with a needle bed in which knitting tools having projections are mounted for raising and lowering, with a cam unit which can be transported past the projections and which has at least one lowering cam acting on the projections of the knitting tools which is adjustable with regard to its lowering depth, on which a runner is movably fastened having a plurality of pathways interacting according to pattern with the runner during the carrying of the cam unit past the projections of the knitting tools for the adjustment of the lowering cam to a preselected lowering depth, and with a controller acting before each passage of the cam unit past the feet of the knitting tools for the shifting of the runner to the position required for the interaction with a selected pathway (FIG. 7).
