Abstract: A method for the protection of blanc areas of sheet metal otherwise coated with layers of synthetic materials, lacquers, foils or the like, wherein the said blanc areas are covered by applying a liquid, viscous or solid rust-protective agent by frictional contact, spraying, welding or cementing and a machine for carrying out the above method, comprising means for applying a liquid or pasty rust-protective agent and/or tape or cord on said areas by temporarily moving the means for applying these agents and/or tapes or cords towards, along and away from the sheet metal and, if desired, pressing the same on and/or drying the same on the sheet metal.

Abstract: Alkali metal or ammonium citrates are produced from solutions of citric acid obtained by chemical reaction or by fermentation by extraction by means of a specific water-immiscible mixture of aliphatic amines and organic solvents and re-extracting the resulting organic solvent mixture with an aqueous solution of an alkali metal hydroxide, carbonate or bicarbonate, ammonia, or their salts.

Abstract: The improved hot dip metallizing process of this invention comprises passing the article to be metallized, such as a ferrous metal article, through a bath of a molten heavy metal, such as lead, and conducting the article therefrom through a layer of molten coating metal, such as zinc, confined in a stack-like structure of a cross-sectional area being a small fraction of the surface area of the heavy metal bath. The molten coating metal is continuously supplied to the stack, preferably through orifices or nozzles so as to remove any droplets of molten heavy metal adhering to the surface of the article, thereby causing metallizing of the article and continuous overflow of excess molten coating metal at the top of the stack. Before hot blasting the coated metallic article it may be passed through mechanical removal means, such as counterrotating rollers to remove the major part of excess coating metal, while the remainder is removed by hot blasting.

Abstract: Novel .alpha.-mercapto-p-biphenylylacetic acids and their derivatives have been prepared. Compounds of this invention possess useful anti-inflammatory, analgesic and antipyretic properties.

Abstract: Novel 1,4-substituted phenyl piperazine compounds have a pronounced effect upon blood coagulation and are useful in the treatment of thrombotic diseases, especially of the arterial system. They are particularly used to inhibit thrombosis of the coronary or cerebral arteries. Examples of such compounds are 1-phenyl (lower) alkyl-2-phenyl-3-keto-4-di-(lower)alkylamino (lower)alkyl piperazines, 1-phenyl (lower)alkyl-2-keto-3-phenyl-4-di-(lower)alkylamino (lower)alkyl piperazines, 1-phenyl (lower) alkyl-2-phenyl-4-di-alkylamino (lower)alkyl piperazines, 1-phenyl (lower)alkyl-3-phenyl-4-di-(lower)-alkylamino (lower)alkyl piperazines and their pharmaceutically acceptable acid addition salts.

Abstract: A radio-photoluminescence dosimeter glass of low energy dependence, high sensitivity, and good resistance to weathering is composed of an activating silver compound such as silver metaphosphate and at least one metal fluoride, preferably of metals of groups I, II, III, and/or IV of the Periodic System. Such a glass may contain at least one further metal oxide, preferably an oxide of metals of groups I, II, and/or III of the periodic System, phosphorus pentoxide, and, if desired, nitrogen pentoxide.
