Abstract: The invention is directed to a method for arc or beam brazing/welding of workpieces (A) made of steel, cast iron, nickel, cadmium, beryllium, titanium, molybdenum, magnesium, aluminum, copper, lead, zinc, tin, hard metal and alloys thereof with workpieces (B) made of steel, cast iron, nickel, cadmium, beryllium, titanium, molybdenum, magnesium, aluminum, copper, lead, zinc, tin, hard metal and alloys thereof, wherein said workpieces (A) and (B) may consist of identical or different metals or metal alloys, using a fused additional metal alloy, characterized by the following steps: a) positioning the workpieces to be joined; b) fusing the additional metal alloy containing an SnZn, SnAg, SnZnAg, SnCu, SnCuAg, SnZnCu or SnZnCuAg alloy; c) applying the fused additional metal alloy on the contact surfaces or partial areas of the contact surfaces between the positioned workpieces; and d) cooling the joined workpieces; steps b) and c) being carried out one immediately after the other.

Abstract: The zinc salt of the hydrolyzed tricarboxylic acid from Diels-Alder adducts or ene-adducts of maleic anhydride to undecylenic acid, preferably in a molar ratio of from 0.8 to 1.2, are described as skin-compatible bactericides and fungicides. They are preferably used in cosmetic preparations. They are more active and less toxic than the substances previously known and used for said purposes.

Abstract: The reaction product of long-chain unsaturated hydrocarbons (fatty derivatives) with maleic acid anhydride and/or maleic acid is added to the salt-containing water of a thermal desalination installation to increase the solubility of the calcium and magnesium salts and prevent encrustation of heating surfaces thereby.

Abstract: Compositions and processes comprising certain metal salts of an unsaturated hydroxy carboxylic acid having 17-21 carbon atoms are disclosed as the active ingredient in various deodorants. Also described are various synergistic agents, anti-oxidants and reinforcing agents which are useful therewith.

Abstract: Method of preventing deposits of dissolved inorganic salts on heated surfaces, such as tubular heat exchangers, is carried out by adding a deposit-preventing agent to the water before contact with the heated surfaces. Compounds complexing with cations are combined with anionic substances which are capable of salt formation with complex bound cations to form additive compositions which are added to the water in the zone near the walls of vessels or tubular heat exchangers subject to deposit incrustation.

Abstract: An apparatus is provided for the continuous molding of hardened resin construction members reinforced with fiber material precisely positioned and arranged during the continuous molding process. The reinforcing fiber material in the form of continuous rovings, woven webs, fabric, fleeces, etc. and having a sizing is fed into an elongated hollow molding duct where the material is first compressed and heated to bond the fibers together at their points of contact to form a grid structure. Synthetic resin is injected into the duct intermediate its ends to impregnate the grid structure and be shaped by the molding duct with the reinforcing fibers contained within the resin. The synthetic resin is then hardened by heating as the shaped resin passes further along the duct forming the finished construction or profile member.
