摘要： A multi-wire oxygen electrode and method of manufacturing the same, said electrode having a reactive electrode surface formed by a glass electrode tip having an end surface and a number of electrode wires are distributed in the end surface of the electrode tip along a circle. The cross-sectional surface of said electrode wires are freely exposed in such end surface and the electrode wires are fused in the electrode tip and electrically conductively connected with a cathode wire arranged in a glass sleeve. There is provided a substantially semi-spherical shaped support surface having an apex, said support surface being coaxially arranged with respect to the electrode tip, and said cathode wire being held in the electrode tip at the apex of the support surface. The electrode wires are electrically conductively secured at the cathode wire at the apex of the support surface, each electrode wire being guided through a substantially one-quarter arc over the support surface and then substantially parallel to the longitudinal axis of the electrode tip to its end surface.

摘要： Apparatus for continuously measuring rates of flow of a liquid has two containers arranged serially in the liquid flow path and each associated with a self-levelling balance beam. Beam displacement is measured capacitively and used to alter current fed to a coil tending to maintain the beam level. The magnitudes of the currents necessary to maintain the beams level is a measure of the liquid level in the containers and is used to keep the liquid levels between pre-determined upper and lower values by controlling valves through which the liquid flows into the containers. The differentials of the currents with respect to time when the liquid levels are falling in both containers, are added. If the liquid level in the first container is rising, however, no differential is provided whereas the differential of the second container liquid level, when rising, is supplied to the adder but negatively. The adder provides an output which is a measure of the volume of liquid supplied by the apparatus.
