    摘要: A gas-insulated single-phase cable for long-distance transport of electricity under high tension, the cable including a cylindrical steel case filled with nitrogen under a pressure of at least 10 hectopascals, an aluminum- or copper-based metal conductor held axially inside the steel case by closed insulating cones, and an aluminum case disposed at a short distance from the steel case and constituting a magnetic screen protecting the steel case from the magnetic field generated by the current carried by the conductor. The steel case is separated from the aluminum case by rings of plastics material or of filled polymer, such as polytetrafluoroethylene. Each rings is placed in a groove in a metal collar, with two adjacent portions of the aluminum case being welded to the collar.

    摘要: Dried agarose or gelose-containing films which are rehydratable into aqueous gel films are disclosed. The dried films are prepared by first forming, on a support, an aqueous gel film containing at most 5% by weight of agarose or gelose and a water-soluble linear polymer or copolymer of acrylamide or methacrylamide. The viscosity of such polymer and copolymer in a 5% aqueous solution at 22.degree. C is about 17000 centipoises or less and preferably about 6000 centipoises or less. The aqueous gel film is then dried according to known techniques, with the linear polymer or copolymer of acrylamide or methacrylamide being included in the dried film.

    摘要: A process for the treatment of polysaccharide gels, especially of agarose or gelose, comprises bridging the linear polysaccharide chains with 2,4,6-trichloro-1,3,5-triazine, e.g. by suspending the polysaccharide gel in a solution of 2,4,6-trichloro-1,3,5-triazine and reacting the two ingredients. The polysaccharide gel may be in the form of pearls, plates or granules. The gels are useful in immuno-electrophoresis processes.
