Title: Electrolytic recovery of zinc
IPC: C22B19/20
Filed: 1975-07-31
Abstract: Iron-bearing zinc sulfide concentrates are leached with a sulfuric acid solution containing hexavalent chromium ions, e.g. chromic acid or a dichromate. The leach solution after separation from undissolved residue is hydrolyzed by heating under pressure at a temperature near or above the boiling point of the solution (ordinarily a range of from about 90 DEG C. to about 250 DEG C.) to precipitate iron as a basic ferric salt. The iron precipitate is separated, the residual solution subjected to zinc dust purification, and the thus purified solution then subjected to a first bifluid electrolysis to electrowon zinc and to regenerate sulfuric acid and reoxidize trivalent chromium ions to hexavalent form. Anolyte discharged from the first electrolysis is subjected as anolyte in a second bifluid electrolysis to oxidize remaining trivalent chromium to hexavalent form, and thereafter the solution is recycled to the leaching operation.

Title: Shearing machines for cutting up waste materials
IPC: B02C18/02
Filed: 1976-09-24
Abstract: The scrap to be cut is poured through a top opening (4) into the shears. A cylinder segment (10) can be pivoted about an axis (13) by hydraulic piston/cylinder drives (10a, 10b) and at the same time forms a carrier for movable blades (26, 27). The scrap is reduced in size at cutting edges (24, 25) of the movable blades (26, 27) and at cutting edges (22, 23) of fixed shearing blades (20, 21) and is conveyed to the outside via chutes (28, 29) in the course of the pivoting movement of the cylinder segment (10). By means of troughs (17, 18) formed on the cylinder segment (10) and defined by webs (14, 15, 16), the poured-in scrap between the cutting edges lying apart in each case is prevented from being cut around and from falling out.

Title: Method for continuously contact-coating one side only of a ferrous base metal strip with a molten coating metal
IPC: B05C9/02
Filed: 1977-03-18
Abstract: Method and means for continuously contact-coating one side only of a ferrous base metal strip with a molten coating metal. One or more roll means are provided to conduct the strip surface to be coated above the surface of a bath of the molten coating metal. The strip surface to be coated is caused to travel sufficiently close to the molten coating metal bath surface that the surface tension and wetting characteristics of the coating metal will permit the formation of a meniscus which will continuously contact and coat the strip surface. The coating is subjected to jet finishing. The strip is maintained in a protective non-oxidizing atmosphere at least until the one side thereof is coated. The strip may be maintained in the protective non-oxidizing atmosphere until it is sufficiently cooled to prevent the formation of a visible oxide on the uncoated side thereof. When the strip is exposed to an oxidizing atmosphere after coating and while still sufficiently hot to form a visible oxide coating on the uncoated side thereof, the strip will thereafter be subjected to acid cleaning, rinsing and drying operations.
Patent ES-458156-A1 (ES)
Title: Non-polluting system for metal surface treatments
IPC: C23C18/18
Filed: 1977-04-09
Abstract: This invention relates to an improved system for preventing water pollution in surface treatment of metals, e.g., in coating base metal parts with an adherent coating of zinc, cadmium or similar protective metal by means of wet impact plating or electroplating, or in chromating or phosphating metal surfaces. A preferred embodiment relates to a wet impact plating process wherein the several solutions used in cleaning or otherwise preparing the work, in plating it and in rinsing it are individually segregated after use and re-used in consecutive plating cycles in a special manner such that release of ecologically objectionable effluent is eliminated and chemical and metal components fed into the process are conserved instead of being discarded after each plating cycle. Consequently, the need for removing pollutants from process effluents can be avoided, the large volume of fresh water heretofore required to operate such a process is greatly reduced and the discard of ecologically objectionable process effluent into sewers is avoided.

Title: Split-ring riser latch
IPC: E21B17/01
Filed: 1978-03-31
Abstract: A latching and unlatching system for connecting a riser pipe to the casing in a subsea well. A split-circumferential ring fits into mating grooves in the male end of the casing and the female end of the riser. A releasing tool runs on a drill pipe suspended within the riser pipe and has a number of radially extendible pistons actuated by hydraulic pressure through the drill pipe to expand the split ring out of the casing groove to the grooved recess of the riser pipe. This releases the riser pipe from connection with the casing so it can then be raised.

Patent ES-8107038-A1 (ES)
Title: Anisotropic membranes
IPC: C08J3/09
Filed: 1980-03-25
Abstract: Anisotropic membranes are prepared from a solution of a membrane- forming polymer in a liquid carrier. The polymer solution is provided in the form of a precursor and is then coagulated in a liquid coagulant comprising water to form the anisotropic membrane. The liquid carrier used in the methods comprises an N-acylated heterocyclic solvent which can be represented by the structure: < IMAGE > wherein X is -CH2-, -N(R')- or -O- R is hydrogen, methyl or ethyl and R' is hydrogen or methyl. The methods are particularly useful for preparing anisotropic hollow fiber membranes. In forming anisotropic hollow fiber membranes, the solution of hollow fiber- forming polymer in the liquid carrier is extruded through an annular spinnerette to form a hollow fiber precursor, and the hollow fiber precursor is coagulated in a liquid coagulant comprising water to form the hollow fiber membrane. The methods are attractive for producing polysulfone hollow fiber membranes which have a homogeneously-formed, thin selective skin on an open cellular support and which exhibit high resistance to collapse. The membranes are especially useful for the separation of gases.

Title: Automatic equalizer for synthesizing recursive filters
IPC: H04B3/03
Filed: 1981-10-22
Abstract: A recursive automatic equalizer is described for implementing the telephone equalization function at a line circuit which may be multiplexed between a plurality of telephone subscriber sets. A recursive digital filter structure having programmable coefficients minimizes the error between the equalizer input and a reference signal. The recursive filter transfer function is variable via feedback coefficient update, with respect to its input and the reference signal. The recursive filter coefficients are adaptively changed to rapidly converge to a final value based upon a mean square error algorithm. The desired filter transfer function can be achieved with a low number of coefficients, for example, five, rather than the heretofore high number of coefficients required in non-recursive filter structures.
