Title: Improvements in or relating to electric arc furnaces
Inventor: HARRISON WILLIAM LEONARD
IPC: H05B7/152
Filed: 1957-06-13
Abstract: 906,711. Electric arc furnaces. A.E.LBIRLEC Ltd. Sept. 15, 1958 [June 13, 1957], No. 18754/57. Class 39 (3). [Also in Groups XXXV and XXXVII] An arc furnace has three electrodes but only one and its associated circuit are shown in Fig. 1. Each electrode 2 is adjustable along a vertical post either by an automatic control mechanism or by a manually operated control. A reference signal circuit includes a variable resistor 6, a rectifier 7 and a voltage-sensitive fault detecting relay 9. Under normal working conditions, i.e. when the tip of the electrode is spaced from a batch of work in the furnace, the relay is energized by a voltage across the rectifier and across lines 8 connected to the automatic control mechanism (not shown). Under abnormal conditions, i.e. when the tip of the electrode is in contact with the surface of, or is immersed in, the work, the voltage across the relay is reduced to zero, the relay is de-energized and a corresponding one of three pairs of contacts 10, 11 or 12 is closed (Fig. 3). The circuit to an electrically operated timer clutch 14 is thus completed and a mator 15 drives the timing device of a timer relay 16. If the automatic control mechanism fails to respond to the drop in voltage by raising the electrode holder to remove the electrode tip out of contact with the work, the timer relay is energized at the end of a predetermined delay and timer-relay contacts 19, 20, 21 are closed so that an alarm bell 17 and lamp 18 are operated and a holding circuit 23 for the timer relay 16 is completed. If the automatic control mechanism responds to the drop in voltage, the electrode holder is raised, the voltage is restored and the relay 9 is reenergized. The closed pair of contacts 10, 11 or 12 is thus re-opened, the clutch disengaged and the drive to the timing device terminated before the alarm bell and the lamp are operated. If the alarm is given, the operator opens the circuit of a supply transformer 4, changes from automatic to manual operation and raises the holder of the electrode which has given rise to the abnormal condition. The alarm circuit continues to operate until isolated. In an alternative circuit, Fig. 2 (not shown), a current-sensitive relay replaces the relay 9 and is operated when current from a coil encircling the supply cable to an electrode reaches or exceeds a critical value.

Abstract: 876,771. Milling. CINCINNATI MILLING MACHINE CO. May 27, 1960 [Sept. 22, 1959], No. 18775/60. Class 83 (3). In a milling or like machine tool having a main cutter spindle and an auxiliary cutter spindle, the latter is driven from the main spindle through a pivotable idler gear selectively meshed with any one of a number of gears in a housing containing the auxiliary spindle. The milling machine, Fig. 1, comprises a column 10 having vertical ways 11 slidably supporting the table 14, and horizontal ways 15 slidably supporting a housing 16. The main cutter spindle 30 carrying a cutter 31 is driven from a motor 33 through a transmission 32 and gears 34, 35, and the auxiliary cutter spindle 39 carried by the housing 16 is selectively driven from the same source, by a gear 56 on the shaft 30, Fig. 3, which engages an idler 69 on a stub shaft 67 mounted in a housing 58. The housing 58 is pivotally mounted on the spindle 30 the limiting positions of such movement being controlled by stops 71, 72 welded to the end plate 70 of the column 10. A shaft 46 is rotatably mounted in the housing 16 and has gears 52a, 52b, 52c splined thereon, the gear 52a being constantly in mesh with a gear 43 splined on a shaft 36 which drives the auxiliary spindle 39 through bevel gears 39a, 39b, and the housing 16 is slidably adjusted on the ways 15 by a rack and pinion 18, 19, Figs. 1 and 2, to bring one of the gears 52a, 52b, 52c in mesh with idler 69. The housing 16 is locked on the column by a gib 22 having a rack 23 actuated by a pinion 25, said gib engaging a longitudinally tapered face on the ways 15, and the tool head 38 may swivel on the housing 16.

Abstract: 1,139,668. Electromechanical delay lines. FRIDEN Inc. 25 April, 1967 [10 June, 1966], No. 18989/67. Heading H3U. To enable a delay line to transmit a high frequency signal it comprises a long delay element 11, e.g. a tape or wire of nonmagnetostrictive material such as a beryllium-copper alloy, and an input transducer consisting of a short length of magnetostrictive material 12 such as nickel surrounded by an input coil 13 having a length greater than that of the material 12. The length of the wave induced in the element 11 is determined by the length of the material 12 and this length may be made very short, e.g. 0À0762 cms., to permit the transmission of waves having a frequency in excess of one megacycle. The length of material 12 comprises a layer and may be formed by electroplating nickel on the element 11. The output transducer consists of a coil 15 surrounding part of a length of magnetostrictive material 14, a bar magnet 16 insuring a uniform magnetic field. Pads 17, 18 absorb acoustic energy at the ends of the line.

Filed: 1926-08-03
Abstract: 269,032. Thornton, A. A., (Radio-Rohren- Laboratorium Dr. G. Nickel Ges.). Aug. 3, 1926. Vacuum tubes.-Electron flow is controlled by means of ions at a pressure of 10<-3> and 10<-4> mm. of mercury, which is maintained by a positive ion emitter. When the valve is first used, the ions are produced by a gas such as hydrogen, previously occluded by the electrodes. In one arrangement, positive ions are emitted by the grid s, which is coated with barium sulphate or iodide, caesium chloride, &c., and is heated to- 600‹-700‹ C. by a regulable current. The cathode is of material emitting electrons at a low temperature. A blue fluorescence appears whenthe valve is in use. In another arrangement, the positive ions are emitted by the cathode, which may be coated over alternate portions with electron-emitting and positive-ion emitting substances ; or it may consist superficially of substances having both properties, e.g. compounds of alkalis and alkaline earths, such as hydrides of caesium, strontium, or barium.

Title: Improvements relating to turbines with a view to reducing the power absorbed by a rotor turning in the opposite sense to its normal direction of rotation
IPC: F01D13/00
Filed: 1954-07-01
Abstract: 766,469. Turbines. SOC. RATEAU, and ANXIONNAZ, R. July 1, 1954 [July 2, 1953], No. 19350/54. Class 110 (3). A turbine having forward and reverse driving stages connected together so that when one stage is operative the other rotates in a direction opposite to its normal direction and acts as a compressor has a by-pass pipe connecting the inlet and outlet ends of each turbine which is open when the turbine acts as a compressor and guiding means at the discharge end of the pipe to direct the fluid flowing through the pipe on to the turbine blades so as to assist the reverse rotation. A three-stage turbine shown, Fig. 1, has a by-pass pipe T connecting the inlet and outlet. When this turbine is driven in the reverse direction it acts as compressor and discharges air through the pipe T and valve V to the turbine exhaust. Under these conditions the valve Vo is closed. The air enters the exhaust through a tore-shaped casing 5, Fig. 4, having guide-blades a which direct the air f on to the turbine blades so that it has a velocity component in the same direction w as the reverse direction of rotation of the blades, as shown in Fig. 5. The casing 5 may be replaced by a volute casing arranged to have the same effect.
