Abstract: The invention relates to a process for producing a coating having a titanium boride content of at least 80% by weight, in which a coating having a thickness of from 0.1 mm to 1 mm, a porosity of not more than 10% by volume and an oxygen content of less than 1% by weight is applied to the surface of a substrate by plasma spraying in an atmosphere which is virtually or completely free of oxygen, with no metallic powder being added to the spraying powder.

Abstract: The invention relates to a support body with a coating of at least 95% by weight titanium boride, said coating having an oxygen content of less than or equal to 1% by weight, a metallic impurities content of less than or equal to 0.5% by weight, and a specific electrical resistance of less than or equal to 10 &mgr;&OHgr;·m at room temperature.

Abstract: This invention relates to a process for preparing printing plates which are used in offset printing. The process produces a plate which comprises a substrate film in which a thin durable hydrophilic layer has been applied thereto. In the process, the substrate film is first microroughened by pressure blasting so that the surface roughness, R.sub.A, is in the range 0.3 to 1.5 .mu.m. Subsequently, a durable, firmly adhering hydrophilic layer is applied to substrate by plasma-spraying an oxide powder with a particle size of 1 to 40 .mu.m onto the substrate. This process produces a plate whose surface is not greasy or grainy.

Abstract: The invention relates to a process for producing a strong bond between copper layers, which have been applied by means of thermal spraying of pulverulent copper or copper alloys, and ceramic. Fine copper powder having a mean particle diameter of .ltoreq.20 .mu.m is applied to the ceramic surface by means of thermal spraying.

Abstract: The printing roller according to the invention comprises a core cylinder and a sleeve of plastic. The sleeve is built up from a tubular base body composed of a fiber-reinforced thermoplastic material and the base body is coated on its outer surface with a layer, produced by plasma-spraying, of copper or a copper alloy.

Abstract: Coating graphite and carbon bodies with a protective layer containing predominantly silicon, by plasma spraying a silicon powder with a grain size under 0.05 mm and with an argon/hydrogen mixture as the plasma gas at reduced atmospheric pressure of at most 200 h Ps. The layer thickness is 0.1 to 0.5 mm and has a density which is at least 95% of the theoretical density. The coated bodies, for instance, graphite electrodes have a lower burnoff rate than unprotected ones in an oxidizing or corrosive atmosphere.

Abstract: A water-soluble, non-polar solvent-soluble fugitive tint for textile materials is provided having the formulaR[(ethyleneoxy).sub.n (Propyleneoxy).sub.m ].sub.xwherein R is an organic dyestuff radical, [(ethyleneoxy).sub.n (Propyleneoxy).sub.m ] is a polymer obtained by combining n moles of ethylene oxide and m moles of propylene oxide, x is from 1 to 6, and said polymer contains from about 40 to 60 mole percent ethyleneoxy units, and the product (n + m).sub.x is from 30 to about 200.

Abstract: Tint compositions for nylon having improved fugitivity properties comprising an admixture of a colorant having the general formulaR{N-[(CH.sub.2 CH.sub.2 O).sub.n H].sub.2 }.sub.xwherein R is an organic dyestuff radical, x is an integer of 1 to 6, and the product of 2n times x is from about 200 to about 300, and at least 30 weight percent of a water-soluble polymeric resin. A minor effective amount of a free radical inhibitor can be incorporated into the tint compositions to retard free radical interaction between the colorant and the nylon.

Abstract: Liquid, water-insoluble colorants and aqueous dispersions of same are provided in which the colorant is represented by the formulaR - (oleophilic polymeric constituent).sub.n,Wherein R is an organic dyestuff radical, the oleophilic polymeric constituent is polyalkylene oxides and co-polymers of polyalkylene oxides in which the alkylene moiety of the polymeric constituent contains at least 3 carbon atoms and such polymeric constituent has a molecular weight of at least 500, and n is an integer of from 1 to 6.

Abstract: A jewelry lockcase in combination with a plurality of hitches pivotally anchored within hollows of the case and protruding therethrough with means of attachment of the case to a chain for the neck, to a band for the wrist of the wearer, to desired jewelry, or as a pin to the wearer's clothing.Means are provided for an easy assembly of the case with the anchor of the hitch.In several embodiments the hitch is a hollow tube including a hollow anchor, with a string knot positioned in the anchor, a spacer sleeve over the hitch abuts the outer wall of the case, followed by a stop-bead threaded over the tube adjacent to the sleeve, the string is threaded through the tube and beads are threaded onto the string extending from the tube.
