  • Patent number: 5415954
    Abstract: Electrical contact outlet for an anode sheet of a lithium generator with polymer electrolyte, consisting of one or more multilayer electrochemical cells. The cell comprises at least one lithium base sheet having a thickness between about 1 and 50 microns to constitute the anode and its collector and additionally includes a cathode and its collector as well as the polymer electrolyte. A lateral end of the anode sheet extends beyond corresponding ends of the cathode and the collector to constitute a projecting zone. A metallic layer consisting of at least one rigid metal which is compatible with lithium is in electrical contact with the lateral end of the anode sheet but without electronic contact with the other components of the cell. The metallic layer constitutes the external terminal of the generator when the latter is in non-finished condition.

  • Patent number: 5143583
    Abstract: Magnetic paper-forming fibers have a particulate magnetic material incorporated within the fibers, as distinct from between the fibers; this can be achieved by loading the lumens of cellulosic fibers with magnetic particles or by generating magnetic particles in situ in a paper-forming fiber which contains ionic groups effective for ion exchange with ferrous ions; the fibers can be employed to produce single layer or multi-layererd magnetic papers for information storage, security paper applications, paper handling, reprographic applications such as magnetographic printing substrate as well as for speciality uses such as electromagnetic shielding, magnetic separation of antibodies based on selective adsorption.
