1482977 Lubricating device R SATZINGER 26 June 1975 [1 July 1974] 27089/75 Heading F2A [Also in Division C7] At least one of the positive and negative surfaces of a bipolar electrode in a gas-generating automatic lubricating device is covered on all but a planar area by an electrolytically inert, insoluble material, e.g. a synthetic material, Sn or an Sn alloy. The electrode has a substantially uniform cross-section in a direction perpendicular to the planar surface. The positive and negative materials may be the components of a bimetal alloy (e.g. Cu-Al) in the form of a cylindrical core surrounded by the inert material. Alternatively the core may be either positive or negative material surrounded by the material of opposite polarity via the intermediary of a layer of the inert material and optionally having an outer inert peripheral coating. In Figs. 4 and 5 a polygonal negative plate 16 carries positive electrode elements 17-20 at its corners, these being surrounded and interconnected by inert material 21, 23-26. |
