Title: Improvements in furnace electrode regulators
IPC: H05B7/156
Filed: 1944-04-17
Abstract: 599,848. Fluid-pressure servomotorcontrol systems. DELAWARE ENGINEERINC CORPORATION. April 17, 1944. No. 7089. Convention date, Aug. 12, 1943. [Class 135] [Also in Group XXXV] The position of an electrode 52 in an electric arc furnace is adjusted in accordance with the current flowing by means of a piston 54 connected to the electrode and working in a hydraulic cylinder 55 in which liquid pressure is controlled by a reversible pump 57 interposed between the cylinder and a tank 59, and the pressure in the latter compensates for leakage in the system and serves to counterbalance the electrode and its support. The pump is driven by an electric motor 62 controlled by an apparatus 63 susceptible to changes in the current flowing through the electrode. An air cushion above the liquid in tank 59 is supplied with pressure air from a compressor 60, although the air cushion may be dispensed with by elevating the tank. The Specification as open to inspection under Sect. 91 comprises also an apparatus wherein the movement of the piston 14, Fig. 1 (Cancelled), is regulated by a valve 17 inserted between the Cylinder 15 and a hydraulic pressure tank 19, the valve 17 being controlled by the regulator 33. When the electrode is to be lowered, valve 17 allows the liquid in cylinder 15 to flow to a reservoir 21, the pressure in which is just sufficient to balance the weight of the electrode &c. As the level of the liquid in the reservoir rises, a float-operated switch 34 starts a motor and pump 24, 23 to pump liquid, e.g. hydro. carbon oil, from the reservoir to the pressure tank 19 past a check valve 25. The pressures in the tank and reservoir are maintained either by forcing air from compressors 27, 30 into the tanks to form air cushions above the liquid, or by elevating the tanks. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,137,679. Electrodialysis cells. WALLACE & TIERNAN Inc. Feb.23, 1966 [Feb.24, 1965], No. 8030/66. Heading C7B. An electrodialysis cell comprises an inner electrode 23, a hollow outer electrode 24 concentrically arranged about said inner electrode, at least one permselective membrane being concentrically arranged between said electrodes and at least one of the chambers thereby formed being filled with divided solid ion-exchange material. If two or more membranes are present, adjacent membranes are made cation-permeable and anionpermeable respectively, the chamber therebetween forming the treatment chamber for liquid to be demineralized or concentrated. As shown liquid to be treated is supplied to the chamber 37 via pipe 46, and also to the outer anode chamber 38 to form an anolyte, which is withdrawn from the anolyte chamber 38 via pipe 52 and passed into the inner catholyte chamber 32. During passage from anolyte to catholyte some of said fluid may be withdrawn through outlet 55b and replenished through inlet 55a. The anion and cation exchange membranes, 28 and 32 may be arranged either such that the liquid becomes demineralized, or becomes more concentrated. The cell may contain a greater number of membranes, arranged alternatively Fig. 3 (not shown), such that a plurality of deminerization and concentration chambers are formed, and the liquid to be treated may be passed through similar chambers either in series or in parallel. The cell may be used for demineralizing water for domestic or industrial use. In a household water softening system including such electrodialysis cell, Fig. 4 (not shown), hard, raw water is passed to the cell via a sand and gravel filter (82) and demineralized water is passed from the electrodialysis cell via a storage tank (83) and pressure tank (92) to service. In a system for demineralizing boiler feed water, Fig. 5 (not shown), raw water is passed to a degassifier (98) in which carbon dioxide is removed by passage through the water of a stream of air, the degassed water is then chlorinated and passed to a coagulator (100) in which it is coagulated chemically with lime and alum which partially softens the water. The resultant water is then passed via sand and gravel filters (106) to a bank of electrodialyis deionizing cells according to the present invention, which cells operate in parallel.
