Abstract: Method and apparatus for continuously electroplating wire or the like wherein two or more drums combine a power supply with a wire turn direction, each drum having a vertical and rotatable shaft, are provided; a wire or the like to be electroplated is wound on the drums in multiple stages so as to be run; an electroplating cell is positioned between the drums so that the wire to be electroplated is arranged to pass in and out of the electroplating cell in multiple stages and repeatedly; and, particularly, an end of the electroplating cell is provided with a slit for passage of the wire to be electroplated, the slit being provided with weir plates placed one on top of another such that the weir plates put each of wires in multiple stages running through the electroplating cell between upper and lower weir plates and passage holes for running the wires at multiple stages are formed at joints between individual weir plates.

Abstract: Anticorrosion copper alloy essentially consisting of 4.5-32 wt % of Ni, 0.3-2.5 wt % of Fe, one or more elements selected from 0.01-1.0 wt % of In, 0.003-0.2 wt % of Pd and 0.003-0.1 wt % of Pt, and the balance of Cu and normal impurities. Further, an anticorrosion copper alloy essentially consisting of 4.5-22 wt % of Ni, 1.3-2.5 wt % of Fe, one or more elements selected from 0.1-1.0 wt % of In, 0.01-0.2 wt % of Pd and 0.01-0.1 wt % of Pt, and the balance of Cu and normal impurities; and said Fe being kept in a state of solid solution in a matrix of said copper alloy.

Abstract: This invention relates to an improvement in a heat exchanger of the type using heat pipes which permits reduction in size of the heat exchanger and enhancement in heat exchange efficiency and more particularly to a cylindrical heat exchanger principally comprising a cylindrical or polygonal tubular casing provided with openings in the middle parts of its upper and lower sides and in its circumferential side, a transverse partition plate which divides the inside of the casing into upper and lower parts and a group of vertical heat pipes arranged to pierce through the peripheral portion of the partition plate in an annular plan configuration as a whole.

Abstract: A galvanic cell separator composed of polyvinyl alcohol having a crystallinity of 0.4 or more to be used with a galvanic cell containing alkaline electrolyte, and a method of manufacturing the same.

Abstract: A process for producing molded product composed of crosslinked resin or coated material composed of crosslinked resin on a substrate which comprises blending a polyolefin-series resin, a compound represented by the formulaX -- Y.sub.m Iwherein X is a group not containing an acetylenic linkage, Y is a group containing an acetylenic linkage and m is an integer of 1 or more, which is compatible with the resin at a room temperature or an elevated temperature, and a compound selected from the group consisting of an amino compound represented by the formula ##STR1## wherein each of R.sub.1 and R.sub.2 is independently substituted or non-substituted aliphatic hydrocarbon, substituted or non-substituted alicyclic hydrocarbon, or substituted or non-substituted aromatic hydrocarbon, provided that at least one of R.sub.1 or R.sub.2 is substituted or non-substituted aromatic hydrocarbon, an amino compound represented by the formula ##STR2## wherein each of R.sub.3, R.sub.4 and R.sub.

Abstract: A solute-separating membrane consisting of a polyoxadiazole series resin containing at least one of the structural units of formulae: ##STR1## wherein Ar and Ar' are same or different multivalent aromatic residues, and R is an alkyl, cycloalkyl or aralkyl group having from 1 to 7 carbon atoms, and swollen to a swelling degree of 1.7-15 with a swelling agent of water, a solvent miscible with water, or a mixture of water and the solvent has a high separating ability and further has high mechanical strength and chemical and thermal stabilities.

Abstract: A method of manufacturing of a novel very fine seamless heat resistant synthetic resin tube having a wall thickness of not more than 0.3 mm, by applying a specific heat resistant synthetic resin varnish as defined in the specification on a metal wire and curing said resin varnish to form the synthetic resin layer on the metal wire, drawing the heat resistant synthetic resin coated wire above the yield point of the metal wire and separating the resulting synthetic resin tube from the metal wire.The method of the present invention may produce a composite heat resistant synthetic resin tube in which a plurality of the above-described tubes are made to adhere tightly parallel with each other in the longitudinal direction or a double layer resin tube, one layer of which is a thermally adhesive synthetic resin and the other layer of which is the heat resistant resin.

Abstract: A power cable having a plastic electrical insulation which is partially or wholly composed of a plastic compound. The plastic compound containing an inorganic or organic electrolyte which ionizes when dissolved in water, the power cable prevents the deterioration of insulation called "water tree" which has been a fatal drawback of the plastic insulation layers of the conventional plastic insulated cables such as cross-linked polyethylene cables, etc.
