Title: Improvements in and relating to electrical circuit arrangements for producing multiple-phase alternating potentials of adjustable phase position
IPC: H02M5/12
Filed: 1934-02-28
Abstract: 425,195. Phase-changing. SIEMENSSCHUCKERTWERKE AKT.-GES., Siemensstadt, Berlin. Feb. 28, 1934, No. 6511. Convention date, Feb. 28, 1933. [Class 38 (ii)] Comprises a phase shifting arrangement in which series connected chokes and impedances 11, 12 ; 31, 32 ; 21, 22 are arranged between the conductors 1, 2, 3 of the A.C. supply, the impedance of the chokes being varied by D.C. saturation and the potentials of adjustable phase being obtained from tappings 13, 33 and 23. With this arrangement the magnitudes of the potential vary. In a modification of this the impedances 12, 32, 22 are resistances and the potentials of adjustable phase are obtained from a transformer the primaries of which are connected across the chokes 11, 31 and 21. In a further modification, Fig. 3, in which the magnitudes of the potentials remain constant, each pair of A.C. conductors is bridged by a centre-tapped choke 14 in parallel with a choke 17 and resistance 16 in series, the impedance of choke 17 being varied by D.C. saturation. The potentials of variable phase are obtained from a transformer, each primary winding 18 of which is connected between the centre-tap of the choke 14 and the junction of the resistance 16 and choke 17. In a modification of this, the chokes 14 are replaced by the centre tapped secondary windings of a transformer connected to the A.C. supply.

Title: Improvements in and relating to the production of highly-concentrated solutions of alkali hydroxide
IPC: F16F9/04
Filed: 1947-03-10
Abstract: <PICT:0627767/III/1> In making concentrated solutions of alkali-metal hydroxides by decomposing alkali metal amalgams, the caustic alkali solution to be concentrated is passed through the compartments of a horizontal soda cell, the liquor following the upper wall of each compartment for the greater part of its length, the passage between the top of the cell or compartment and the top of the end partition of the compartment being so arranged that in addition to the caustic alkali solution, the water vapour produced and the hydrogen evolved are allowed to pass, and the hydrogen and water vapour entering the following compartment at its base and there bubbling through the solution, so that the heat produced or recovered in one compartment passes into the next.  In one form of apparatus, the amalgam from brine cells enters a soda cell, at a high temperature, at head E by a tube 8 dipping into a hydraulic seal 9, overflows on to the base of the cell in contact with graphite grids 5 and, passing from one compartment to the next by hydraulic seals 3, arrives free from alkali metal in the last compartment A which is provided with heat exchange blades 4 and from which mercury is returned to the brine cells.  The water necessary for the decomposition enters compartment A, absorbs heat from the mercury by means of the blades 4, and the steam thus formed, together with hydrogen evolved and water, pass into the next compartment B1 by partitions 1 and 2, this process being repeated in each succeeding compartment, in the last of p which hydrogen accumulates in a collecting dome 6 and is separated from alkali solution in a separator 11 of known type.  Where the temperature in the brine cell is lower than that of the soda cell, the amalgam may be introduced not into the final compartment of the soda cell, but into another compartment at lower temperature; two cells can then be put in series, the mercury and liquor circulating co-currently and counter-currently in the first and second cells respectively, Fig. 2 (not shown), being a combination of two such cells.  Specification 612,322 is referred to.

Filed: 1973-02-10
Abstract: 1424471 Casting processes MEIGH CASTINGS Ltd 31 Jan 1974 [10 Feb 1973] 6648/73 Heading B3F A method of casting comprises moving a mould box into engagement with a bar (15) positioned adjacent the discharge outlet of a launder leading from a furnace, tilting the box into a position inclined to the horizontal, and thereafter effecting controlled pivotal movement of the mould box into a horizontal position while pouring metal into the mould cavity by passage along the launder. The apparatus includes three frames 10, 12 and (14) movable relative to one another by hydraulic rams. The first frame 10 has a pair of spaced side members 11 between which extend a plurality of rollers and is movable relative to the second frame 12 by rams 13 having piston-rods 18. The third frame (14) includes a pair of vertical columns 33 between the upper ends of which the bar (15) extends and on which the ends of side members 20 of the second frame 12 are pivotally mounted. In use, a mould box is moved along a roller conveyer into the required position in the first frame 10 and the frame 10 moved vertically by the rams 13 until the upper surface of the mould box engages the bar (15). Upward movement of the frame 10 is then stopped and the frames 10 and 12 pivoted together about the axis of the bar (15) by means of rams 22 and 23 until the mould box is substantially vertical. Molten metal is then introduced into the mould while the frames 10 and 12 together with the mould box are returning to their horizontal positions.

Title: Metal shaping processes
IPC: B21D5/08
Filed: 1974-02-15
Abstract: 1501622 Rolling; forging INTERNATIONAL HARVESTER CO 13 Feb 1975 [15 Feb 1974] 6998/74 Headings B3M and B3H Apparatus for roll forming a metal workpiece includes electrodes of refractory metal which serve both to reduce the workpiece and to supply an electric heating current to the workpiece. The electrodes may be rolls which define cavities whose shape is to be imparted to the workpiece. The apparatus is suitable for forming workpieces of, e.g., titanium, beryllium, and alloys of nickel and titanium. Suitable forming rolls, which may operate at up to 2500 F. may be of molybdenum, tungsten, niobium, tantalum, or their alloys. The forming may take place in an argon or inert atmosphere, and a lubricant of flaked graphite or silver, or tungsten powder in a plastics binder may be used. In one form of apparatus, Fig. 8, which is used to roll I-beams, the upper and lower work rolls 92 and 94 serve as electrodes through which an electrical heating current is fed to a workpiece. Guide rolls 126 and 138 which are in sets of three in either side of the workpiece, apply a working pressure, the rolls 138 being biased hydraulically towards the workpiece. The rolls 126 and 138 are mounted in a frame 118 which may float vertically in use. The heating current may be A.C., D.C., or a combination of both and may be controlled by a feedback loop to provide a desired workpiece temperature. The workpiece temperature, which is at its highest immediately adjacent the work rolls, is sensed by an optical pyrometer and compared with a set value. In a similar manner, the rolling load on the workpiece can be maintained constant by the use of a feedback loop incorporating load cells. The workpiece may be force fed towards the roll gap by feeding rolls (which may have serrated surfaces) and may also have a tension applied hydraulically to it on the output side of the apparatus. After rolling the work may be bead blasted or heated to provide stress relief. The work rolls may be provided with replaceable inserts. A rectangular bar may be formed in successive stages to an E-section, Figs. 14A, 14B, or a turbine blade may be die rolled between rocking rolls 430, 432, Fig. 15. In a further embodiment, Fig. 16, a workpiece is deformed between anvils 454, 456 which act as electrodes. The current density is controlled by a detector 466 to keep the forging temperature at the requisite level.
