Title: Tyre Band Stretching Shaping and Vulcanizing Machine.
Inventor: THORNTON ALFRED AUGUSTUS
IPC: B29D30/36
Filed: 1918-12-20
Abstract: 136,890. Thornton, A. A., (Dykes, J. L. G.). Dec. 20, 1918. Vulcanizing - presses; cores for.-Relates to tyre-band stretching, shaping, and vulcanizing machines. The tyre-band 11 is placed in a support b encircling the members 19, 20 of an expansible mandrel. The members 19, 20 are mounted on carriers G, g, sliding in guides ! on a table B. A ram E raises the table C, the cams 3, 5, 6, 9, 10 forcing the members 19, 20 to the position shown in broken lines in Fig. 3. When expansion to the full extent has taken place, a mould 24 carried on the table C lifts the tyre and mandrel into engagement with the mould 25, as shown in Fig. 2, the members 19, 20 being attached to the carriers G, g only by dowel pins 21. The tyre is then vulcanized by the admission of steam to the chambers 26, c. A ring 23, Fig. 2, may be placed in the mandrel to retain it in the expanded position, and the mandrel removed from the machine. Fluid is admitted to the cylinder F through a valve z controlled by a weighted arm 31. The upward movement of the table continues until a lever 37 engages a stop 35 on the rod 32, and lifts the arm 31, closing the valve. At this point the expansion of the tyre is complete. To move the tyre and mandrel to the position shown in Fig. 2, the lever 37 is moved out of engagement with the stop 35 and allows the table C to rise until it engages a stop 36, at which point the tyre and mandrel are in the top position. Specifications 136,888 and 136,889 are referred to.

Abstract: 203,003. Akt.-Ges. Brown, Boveri, et Cie. Aug. 28, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Commutating poles and windings; short-circuited screens on poles. - The commutation of continuous-current machines liable to sudden variations in load is improved by providing one or more closed windings which are interlinked with a flux dependent upon the armature current and in which windings an increase in this flux induces currents that strengthen the commutating-pole field. In one form, Fig. 2, the closed winding is situated in one or more slots in the faces of the main poles P1, P2, and is interlinked with the flux #w of the commutating pole W and with the transverse armature flux #a. In a modification, Fig. 3, the closed winding Z is interlinked with the dispersion flux #s of a commutating pole. Instead of providing a separate closed winding, the commutating- pole winding may be in two parts W1, W2, Fig. 4, connected in parallel and dimensioned so that the coil W1, for example, carries the greater current. Resistances may be arranged in the circuit of the closed windings.

Title: Improvements in or relating to control systems for electric arc furnaces
IPC: H05B7/00
Filed: 1947-08-08
Abstract: 629,394. Automatic control systems for arcs. ASKANIA REGULATOR CO. Aug. 8, 1947, No. 21907. Convention date, Dec. 2, 1943. [Class 38 (iv)] [Also in Group XXIX] A control system for an electric arc furnace 9 comprises a reversible hydraulic motor 14 for adjusting the electrode 11, the motor being controlled by a pivoted jet-type regulator 26, spring-biassed so as to cause the motor to raise the electrode, and electrical means responsive to variations in the condition of the arc from a preselected condition are arranged to act on the regulator to move the electrode and restore the preselected condition. As shown, three electrodes 11 are connected to a 3-phase supply, each electrode being movable through a cable 18 by the motor piston 15 which carries a balance weight 17 and is controlled by the jet 26. A spring 40 biasses the jet to supply fluid to the top of the piston 15. Two solenoids 49, 51, energized by the voltage applied to the electrode and the current across the arc respectively, apply a torque to the pivoted beam 43 which is connected to the jet 26. When power is supplied to the electrode, the solenoid 49 is energized and overcomes the spring 40 thus causing the electrode to be lowered. Should the electrode strike the melt without arcing, the cable 18 slackens causing a spring-loaded switch 64 to open and de-energize the solenoid 49, thus raising the electrode which hunts at the level of the melt until an arc is formed. When this occurs, the solenoid 51 is energized and the electrode is raised until the predetermined arc is formed. Fluid is delivered to the jet by an electrically-driven pump 80, which also supplies an auxiliary reservoir 88 connected to a source of compressed air. On failure of the electric supply, the compressed air forces sufficient fluid to the jet to raise the electrode. In a modification, the current energized solenoid is the only control for the jet; the voltage energized solenoid merely applying a load through a spring to the pivoted beam.

[Also in Division G4] An integrator (see Division G4) includes pulse frequency discriminating circuits which detect whether individual rectangular pulses are longer than or shorter than predetermined limits. A lower frequency limit detector comprises a capacitor C, resistor R and diode 84 which pass only the overshoot of a rectangular pulse applied to its input. The overshoot is applied through an adjustable resistor 86 to a Schmitt trigger 88. Since the size of the overshoot increases with the length of the pulse, the Schmitt trigger operates only when the pulse is of greater than predetermined length. An upper frequency limit detector has a diode 96 which removes the overshoot from a rectangular pulse which has been passed through a capacitor 90. The remaining portion of the pulse is applied through a circuit comprising a capacitor 100, a variable resistor 102 and resistor 104 to the Schmitt trigger which responds to the second overshoot, the size of which overshoot is larger for shorter, higher frequency pulses.
