Title: Improvements in or relating to Electric Arc Furnaces.
IPC: H05B7/02
Filed: 1917-12-19
Abstract: 130,020. Coates, H., and Watford Electric & Manufacturing Co. Dec. 19,1917. Furnace details.-In combination with an automatic arc-furnace regulator controlled in accordance with the current strength, there is employed a pressure-controlled switch which in its normal position permits the usual operation of the regulator, but, when the pressure falls abnormally low, modifies the action of the regulator or substitutes ether means so that the arc is lengthened more rapidly by a continuous movement. Tripping of the circuit-breaker of the furnace is thus prevented, and hand regulation'of the electrodes at starting is rendered unnecessary. If current is cut off from the furnace, the electrode is raised until stopped by a limit switch. In an arrangement shown in Fig. 1, the primary shunt device consists of an electro-magnet H and a pivoted armature H<2> controlled by a dash-pot K and adjustable weight K<1>, and wound with closed coils H<3>. A live contact-arm J cn the armature is arranged between two spring-plunger contacts J<1> so that it never leaves both at once. Current from an auxiliary circuit d passes through a resistance R to the contact-arm J and either through an idle return wire j or through two electro-magnets L, G. In the latter case, i.e. when the furnace pressure is normal, the electro-magnet L breaks a circuit at L<3> through a solenoid A, the descent of the solenoid-core being aided by the electro-magnet G. A cross-bar A<2> spring-mounted on the core is linked to switch arms B, normally resting against contacts C, so as to connect the regulator leads c to the motor-armature circuit v. When the main pressure is too low, the solenoid moves the arms B on to contacts D directly connected to the auxiliary supply circuit d. During movement of the arms in either direction, rollers B<3> thereon temporarily depress spring-controlled levers E on to resilient contacts F, so as to connect the motor armature to a braking-resistance f. In another arrangement, the switch A, B, C is omitted, and the switch L closes a circuit from auxiliary supply mains s, Fig. 3, through a coil o, which in turn continuously closes the motor circuit. This coil o, when the current-controlled regulator is in normal action, is supplied with intermittent current through an interrupter P and switch Q<2> operated by a coil Q<1> in series with the secondary Q of a transformer excited by the main current; thus an intermittent feed is produced. A similar current-controlled regulator may be used in the first arrangement described.

Abstract: 893,385. Controlling clutches. LINDE'S EISMASCHINEN AKTIENGESELLSCHAFT ZEIGNIEDERLASSING GUELDNER MOTORENWERKE, GES. FUR. June 5,1959 [June 7, 1958; Sept. 3, 1958], No. 19316/59. Class 80 (2). [Also in Group XXXI] Separate control-members for operating the clutch, accelerator, gear change and brake of an agricultural tractor may be operated from a single lever. The lever 1 is connected to a shaft 2 rotatably mounted in a control-box 3 and has rigid therewith a cam 10 and cranks carrying rollers 11 and 12. A roller 15 carried by a lever 14 is spring-urged into contact with the cam 10, the lever 14 being connected to the brake pedal 17 through a link 5. The rollers 11 and 12 cooperate with a cam 19 and a crank member 22, respectively, mounted upon a shaft 22, the cam 19 being connected through a crank and link 6 to the clutch pedal 21 and the crank 22 by a crank and flexible cable 7 to the gear shift lever 9. As shown in Fig. 2, the lever 1 is in the position wherein the tractor is at rest, the brakes being applied and the gear lever in the neutral position. The lever 1 is moved anticlockwise from this position to that of Fig. 3, rotating the shaft 2 and thus, by co-operation of cam 10 and roller 15, the brake is released, by co-operation of roller 11 and cam 19 the clutch is actuated, the shape of cam 19 providing that the clutch pedal moves through a disengaged position back to an engaged position, and the roller 12 co-operating with the crank 22 moves the gear shift lever, through the coupling 7, to a position whereby a forward gear is selected. Through another cam mechanism, not shown, the accelerator pedal is actuated. The lever 1 can be operated from a position near the tractor so that short journeys with frequent stops may be undertaken. In a modification, the shaft 2 may be rotated by a crank 56, Fig. 6, in response to movements of a piston 54 initiated by a piston 60 in an hydraulic circuit, the piston 60 being moved by a lever 51. An alternative hydraulic circuit is shown in Fig. 7, the movement of the piston 74 in one direction being caused by a spring 78. The hydraulic operation of the shaft 2 may be used to provide remote control points, the operating cylinder being located, e.g. on a mudguard. The box 3 may contain oil and a damper mechanism, 27, Fig. 4, may be attached to the shaft 20. A spring device to prevent strain on the gear shift lever, Fig. 5, may be included in the box 3, and comprises a piston 32 acted upon by a compressionspring 36. Should the gears not mesh properly, the spring 36 is compressed, the piston 32 resuming its proper position when the gears change position to become properly meshed. A damping effect is provided by the co-operation of the piston 32 with the cylinder 31 and small outlet holes 37.

Title: Improvements in or relating to unloaded telephone circuits or the like
IPC: H04B3/40
Filed: 1923-07-31
Abstract: 223,336. General Electric Co., Ltd., and Bartlett, A. C. July 31, 1923. Artificial lines or networks for balancing unloaded :telephone circuits and like lines with uniformly distributed impedance, have the dimensions of their impedance elements calculated from the impedance constants of the telephone circuit. The network may consist of a number of T- section elements comprising equal series resistances r<1>, Fig. 2, connected on opposite sides of a shunt impedance consisting of a resistance r<2> in parallel with a condenser C<1>. Formulµ are given in the Specification for the values of r<1>, r<2>, and C<1>, in terms of L, C, R, and S, respectively, the inductance, capacity, resistance, and leakage conductance of the telephone line per unit length. For absolute accuracy an infinite number of the T-sections should be used, but in practice for aerial telephone lines three sections give a balance sufficiently accurate for frequencies between 200 and 2,000. For the unusual case in which the leakage conductance S is great enough to make SL greater than RC, the capacity C<1> is replaced by an inductance, and new values are assigned to r' and r<2>. Fig. 5 shows a modification in which each section of the artificial line comprises equal shunt resistances r<2> connected at opposite ends of a series resistance r<1> and series condenser C<1>, the values of r', r<2>, and C' being stated in the Specification in terms of L, C, R, and S. When the telephone line is such that SL is greater than RC, the condenser C' is replaced by an inductance, and new values are assigned to r<1> and r<2>. In the case in which the leakage conductance S is zero, each section of network may comprise series resistance and inductance with equal shunts on both sides consisting of resistance in series with capacity.
