Title: Protection of graphite electrodes
IPC: H05B7/12
Filed: 1972-07-19
Abstract: 1386611 Coated electrodes FOSECO INTERNATIONAL Ltd 27 Nov 1972 [26 Nov 1971 19 July 1972] 55128/71 and 33839/72 Heading B2E [Also in Divisions C1 C7 and H5] A graphite arc furnace electrode which is supplied with electric current for heating has a protective coating over its entire surface except that which is intended to make electrical contact with the electrode clamp. The coating comprises 15-90% by weight of a matrix material having a melting point below 1000‹C and which is a graphite melting material, and 10-85% by weight of a refractory filler. In an arm furnace in which an electrode is supplied with current through an electrode clamp and fed into the furnace, the portion of the electrode in contact with the clamp is uncoated. The coating may be applied as the electrode is being lowered into the furnace or alternatively it may be coated, except for the surface to be engaged by the clamp, away from the furnace. The coating may be applied automatically on raising or lowering the electrode through a spray ring or a system of individual jets between the electrode clamp and the furnace chamber. The coating may be applied as a powder onto a hot electrode or a suspension on to a hot or cold electrode by spraying, brushing, dipping, rolling, or smearing. The coating application may be assisted electrostatically. The electrode may be heated in the furnace or may be heated before or after application of the coating by, flame, induction, microwave or infra red heating. The coating comprises the matrix having a melting point below 1000‹C and a refractory filler and which may be suspended and dissolved in a liquid carrier e.g. water. After heating the matrix fuses so that in use it forms with the filler a liquid or plastic impermeable layer. Matrices may be boric oxide, metaboric acid, boric acid, salts of these acids e.g. sodium borate, or vanadium pentoxide. Alternatively the matrices may be combinations of glaze forming materials e.g. phosphates, fluorides, silicates e.g. alkali metal phosphates, aluminium ortho phosphate, alkali metal silicates, glass, calcium fluoride, sodium aluminium fluoride, sodium borofluoride. Combinations of matrix materials may be used. Chrome ore may be added to certain of these materials to improve wetting of the graphite. Fillers may be refractory oxides, carbides, nitrides or borides such as chromic oxide, zirconium oxide, titanium oxide, silicon carbide, zirconium carbide, tungsten carbide, boron nitride, titanium boride or zirconium boride. 80% of the filler particles are less than 0.5mm preferably less than 0.2mm and more preferably 0.06mm. Small percentages e.g. less than 10% of refractory fibrous material e.g. asbestos lagwool, glass fibre or aluminosilicate fibre may be incorporated in the coating. More than one layer of coating material may be applied and a referred furnace electrode may be removed at intervals to have a further coating applied.

Title: Electrical control system for a machine tool
IPC: B25H7/04
Filed: 1973-07-23
Abstract: 1427244 Cutting by fusion MESSER GRIESHEIM GmbH 23 July 1973 [22 July 1972] 34965/73 Heading B3V [Also in Division G3] For a machine 10 {flame, laser, or plasma cutting} with at least two tools 21, 22 and arranged to be controlled either by a photoelectric line follower 11 or numerical continuous path controller 12, for partly cutting, partly centre-punching a workpiece, there is provided in the signal line between units 11 or 12, and the machine, a correction device 70 which can modify the data input to represent an offset in one or more of the co-ordinates X, Y with respect to the input data, the offset corresponding to the distance between the tools. As shown, the photo-electric line follower provides for each axis, a three phase, or two phase (quadrature) A.C. signal which, via synchro units (61, 62), Fig. 2 (not shown), (50), controls the respective flame cutter drives, carriages 18, 19 following the same contours in conjoint motion. The offset is provided by synchro (71), Fig. 3 (not shown), whose rotor is set to an anular position pre-set by stop (81) against which pin (82) fixed to the rotor bears, and representing the desired data offset, the synchro providing a corresponding phase shift in the A.C. signals from line follower to machine. During oxy-gas flame cutting, contacts (87-89, Fig. 2) are closed, cutting taking place without data offset. When a pulse line 91 or 92 on the drawing is encountered contacts 83-85 close, (87-89) opening, the so introduced offset representing the distance 23 in sense and magnitude between the cutter 21 and electropneumatic centre punch 22, the latter assuming a position to continue on the line of cut, cutter 21 having been switched off, punch 22 activated, by the detected line 91. Should the traced line not be perpendicular to the line joining cutter and punch, offsets are introduced in both X and Y co-ordinates. The offset may be introduced manually by switching in the synchro (71) or by adjusting the rotor angle from a zero phase value, to the desired offset position for centrepunching. Synchro (71) may be replaced by a quadrature resolver, or an electronic phase shifting circuit. The system may be used to provide offsets in X, Y, and Z for a three-axis machine, a single motor moving the rotors of three synchros to corresponding preset angles. The signals from line follower 11 are derived from synchros (46, 60, Fig. 2) driven by the motors driving the follower head (35).
