846,006. Electrical storage devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 21, 1956 [Dec. 30, 1955], No. 39124/56. Class 37. A two-terminal storage device, similar to a coherer, consists of a body of granular conducting particles in an insulating binder and becomes conducting in response to the application of an appropriate voltage from a source 13 and non- conducting in response to current flow from a source 17 of lower voltage. The granular particles may consist of powdered iron, tin, aluminium or carbon the best result being obtained with metals whose oxides have a higher melting point than the -pure metal. The size of the particles is preferably less than 44 microns. The insulating binder may be of any suitable plastic material for example epoxy resin and may include an inert filler such as titanium oxide, asbestos, magnesium dioxide, silica gel, or ferric oxide. The binder and conductor should be present in roughly equal proportions. A slight trace of detergent material such as " Tergitol " (Registered Trade Mark) creates a more intimate mixture of the conductor with the binder. |
