摘要： A porous gas diffusion electrode comprises a plurality of layers (6, 7, 8, 9, 10) of conducting tape having transverse channels, the layers of tape being superimposed one upon another with their edges aligned to form the two sides (12,13) of the electrode respectively. The open sides of the channels in one layer are thus closed by the overlying layer to form preferably tapered, transverse passages (11) extending from one side of the electrode to the other and thus providing the porosity of the electrode. The conducting layers may be formed from a single continuous tape which has been coiled to form a flat disc or a cylinder.

摘要： The invention provides an apparatus and method for monitoring the electrical conductivity of a web surface in which a forwardly moving web is exposed to an electrical field generated by a forwardly extending high voltage source so disposed adjacent the web as to induce a transverse redistribution of the electrical charges present on the web surface, the electrical field signal generated by the redistributed surface charges of opposite polarity to that of the source being monitored by a suitable field detector. Surface conductivity of a web may therefore be continuously and reliably monitored by a non-contacting technique, and the system is particularly suitable for controlling the level of antistatic behaviour induced in polymeric packaging films.
