    Abstract: A noise barrier pad and a method for the production of same comprises the steps of forming a tread layer by reacting a mixture for polyurethane foam in a hollow mold having separable upper and lower parts and which is shaped so as to form the tread layer, curing the foam, removing the upper part of the mold, placing a blank of noise barrier material on the surface of the foam which corresponds to the bottom side of the tread layer, and forming a bottom foam layer on the tread layer and barrier material by placing another upper mold constructed in accordance with the bottom layer of the noise barrier pad and defining a cavity over the tread layer and barrier material and filling the cavity with the reaction mixture for the polyurethane foam.

    Abstract: A radial shaft seal, which includes a ring-shaped, metal supporting body and a sealing lip disposed thereon, in order to separate a hydraulic side that is particularly under high pressure, from an atmospheric side, the sealing lip being pressed onto the shaft by an annular helical spring. In an uninstalled sealing ring, the working plane of the annular helical spring has a value x that is less than zero with respect to the working plane of the sealing edge, and in an installed sealing ring, the two working planes are approximately coplanar.

    Abstract: A method for the selective recovery of cadmium, nickel and cobalt from a nickel-cadmium battery waste which comprises:A. leaching the waste with an ammoniacal carbonate solution to form an aqueous ammoniacal carbonate solution containing cadmium, nickel and cobalt (II) ammine complexes and a leaching residue. Any iron in the waste is in the leaching residue.B. adding air to the aqueous ammoniacal carbonate solution to oxidize the cobalt (II) ammine complex to cobalt (III) ammine complex.C. contacting the resulting aqueous ammoniacal carbonate solution with a substantially water insoluble organic solution which contains a hydroxyoxime which forms a nickel compound readily soluble in the organic solution with any nickel present but which does not affect cadmium and cobalt (III). Nickel is thereby removed.D. precipitating the cadmium as a carbonate by removing ammonia from the aqueous ammoniacal carbonate solution and then removing the cadmium in the form of a carbonate.E. withdrawing a portion of the aqueous ammoniacal carbonate solution from the preceding step after precipitation of cadmium and precipitating the cobalt by removal of ammonia.F. returning the ammonia from the preceding step to the cadmium free solution in step (D) and replacing lost carbonate ions by adding carbon dioxide in gaseous form. The resulting solution can then be reused in step (A).G. stripping the nickel compound in step (C) by washing with an aqueous solution of sulphuric acid to strip the nickel as nickel sulfate. The organic solution stripped of nickel can thereafter be reused in step (C).

    Abstract: A process is described for regenerating a spent ammoniacal etching solution containing copper values. The process comprises extracting copper from the spent etching solution by means of an organic solution containing a reagent which is capable of selectively extracting copper ions from the spent etching solution. The process also comprises extracting copper from the washing water originating from the etching process.

    Abstract: Metal can be recovered from metal-containing waste by means of liquid extraction processes. The waste is leached with sulphuric acid. The resulting metal sulphate solution is contacted with an organic solution of a reagent, so as to extract iron and zinc to the organic solution. The organic solution is washed with sulphuric acid in two steps, viz. with weaker acid in the first step, so as to transfer zinc to the washing solution, and with stronger acid in the second step, so as to transfer iron to the washing solution. Zinc and iron have now been separated, and are recovered from the washing solutions in known ways, for example by crystallization. If the waste contains other metals, in addition to iron and zinc, additional selective liquid extraction processes are added, before or after the iron-zinc-extraction.
