Filed: 1970-01-27
Abstract: 1276246 Brakes VEREINIGTE OSTERREICHISCHE EISEN- & STAHLWERKE AG 27 Jan 1970 [11 Feb 1969] 3815/70 Heading F2E In an apparatus for the automatic operation of the locking brake of tiltable metallurgical vessels and which comprises a control element to which a mains supply voltage is applied and which initiates operation of a brake release device in response to failure of the mains supply voltage, there is provided an electrically operated brake-releasing device 8, e.g. a solenoid motor-driven or electromagnetic-hydraulic device, for the brake and an emergency electric power source independent of the mains and comprising a storage battery 11 and a converter 14 for transforming the battery current into a current equivalent to the mains supply current so that failure of the mains supply current causes the device 8 to be energized by the emergency electric power source and the control element to operate the brake-releasing device so as to release the brake for a period of time in which the vessel is returned to a predetermined position. As shown, a motor 2 drives, by a shaft, a transmission for tilting the vessel, the shaft carrying a brake disc 1 engageable by shoes 3 mounted on levers 4 connected by a linkage 5 operable by a lever 6 which is acted on by a spring 7 and by the device 8, the latter being normally energized by the mains 10. Upon failure of the mains supply a mainsdependent switch 13 connects the converter 14 to the battery 11 and to device 8 to release the brake. When the vessel has reached a predetermined position a switching cam 16 connected to the vessel actuates, by a cam follower 17, a switch 18 which disconnects the converter 14 so that the device 8 is de-energized and the brake is re-applied by the spring 7; alternatively, the switch is replaced by a timer or limit switches. When normal voltage has been reestablished in the mains 10, the switches operate to disconnect the battery and converter.

Abstract: 770,997. Automatic control systems for arc furnaces. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 9, 1955 [Feb. 12, 1954], No. 4221/54. Class 38 (4). In order to prevent excessive operation of a surge-actuated circuit-breaker in the supply to an arc furnace electrode, an amplidyne generator supplying an electrode-positioning motor has a field energized when a surge exceeds a value somewhat below that at which the circuit-breaker is operated, whereby the electrode is withdrawn to tend to reduce the surge. As applied to a three-phase arc furnace, an electrode-positioning motor 7 is connected with an amplidyne generator 8 in a Ward-Leonard loop, the generator field winding 18 being energized to maintain a constant ratio of arc voltage to arc current. The circuit-breaker trip device 4 and a relay 5 are responsive to excessive electrode current signals in current transformer windings 1,' 2, 3, the relay being actuated at a lower surge value than the trip to energize a relay winding 16, and thus close a contact 26 to energize a second generator field winding 28 from a D.C. source. The motor 7 is thereby actuated to withdraw the electrodes before the trip operates to break the supply circuit. The electrodes may be separately positioned by individual motors controlled by relays responsive to the current in each phase. The operating, coils in relay 5 and trip device 4 may be connected in series.
