Abstract: The purification apparatus includes UV-tubes and secures a continuous and uniform disinfection or purification, respectively, of a flowing medium such as water, independent which portion of the space containing the UV-tubes is flowed through by such medium. The purification apparatus comprises a cylindrical pressure vessel with two chambers arranged on top of each other and separated from each other by a partition wall. The lower chamber comprises an inlet opening for the medium which is to be purified. The cylindrical upper chamber communicates with the lower chamber by inlet parts for the medium arranged on the partition wall and arranged groupwise along various concentric circles, each having a different radius. Inside of the vessel there is arranged an outlet tube, the upper portion of which is located in the upper chamber and comprises an inflow aperture at its upper end and the lower portion of which penetrates the partition wall and lower chamber and comprises at its lower end the discharge opening of the vessel. In each inlet part of the partition wall a UV-tube is supported at its lower end by the agency of guide vanes which produce a circulation of the incoming medium around the respective UV-tube. The UV-tubes extend through the upper chamber and penetrate an upper center plate and are supported at their upper end in a wall of the vessel remote from the inflow side.

Abstract: A fabric is made up of an elongated strip of a hairy-coated skin of a fur-bearinq animal. The fabric is formed by twisting the strip such that the skin (28) forms a core and the hair (30) stands substantially radially outward therefrom. The twisted strip is then combined with like twisted strips and also, if desired, one or more threads or cords (42) of non-furry material. and is knitted, crocheted or woven to form the fabric.

Abstract: The invention provides a process for the preparation of formic acid by hydrolyzing methyl formate with water at high temperature and pressure in the presence of a formic acid catalyst. Methanol is also formed. The reesterification of the reaction products to methyl formate (a reaction favored by high temperatures) is minimized by flashing the reaction product at relatively low pressure and temperature and thereafter distilling the residual liquid. Thus procedure separates the methyl alcohol from the formic acid with a minimum contact time and at a low temperature which does not favor the reesterification reaction. High purity formic acid may be obtained by subjecting the bottom from the vacuum distillation of further distillation. 
     In a preferred embodiment of the invention, prior to the main hydrolysis, the methyl formate is partially hydrolyzed to form the small amount of formic acid needed to accelerate the main hydrolysis step. Accordingly, the necessary formic acid catalyst is formed in situ, thus eliminating the need to add formic acid or to recycle product'formic acid.

Abstract: A device for plating a thin layer of a first metal onto the surface 10 of a generally flat metal strip B formed of a second metal as the strip is moving in a selected direction along a given path includes an anode 50 and means for supplying electrolyte L containing ions of the first metal between the anode 50 and the moving strip. The anode comprises an electrically conductive, non-consumable, anode element 100 having an outer surface 102 with a transverse width substantially as great as the width of the strip. A plenum chamber 112 is formed behind the anode element 100 and generally coextensive with the outer surface of the element so that apertures 70 in the anode element direct jets of electrolyte through the anode element 100 and directly against the surface 10 being plated to provide a uniformly turbulent flow of electrolyte at the surface of the strip.

Abstract: This invention relates to negative x-ray resists useful in the production of high-resolution patterned images. The x-ray resist contains a mixture of poly(2,3-dichloro-1-propyl acrylate) and poly(glycidyl methacrylate-co-ethyl acrylate), with the latter forming between 1 percent and 20 percent by weight, of the total polymer mixture. This ray resist has adhesive and resolving properties superior to those of poly(2,3-dichloro-↑- propyl acrylate). Superior properties of the mixture are attributed to the fact that the two polymers form a compatible polymer mixture which is a relatively rare and unpredictable event in polymer chemistry.
