Title: Improvements in and relating to the production of iron and steel and alloys thereof
IPC: C21B13/14
Filed: 1940-09-04
Abstract: 559,295. Extracting iron ; iron alloys. LIPINSKI, A. V. VON. Sept, 4, 1940, No. 13872. [Classes 72 and 82 (i)] In the production of iron and steel from ore, the ground ore in small granules is heated directly by electric resistances in a tunnel furnace to 500-1000‹C. and reduced with hydrogen, the spongy iron then separated, e.g. by magnetic separation, from the gangue, moulded into briquettes and melted with additions to form refined iron or steel. The granules may be up to 2 mm. in size and the hydrogen may be circulated in a circuit from which harmful gases are removed. Ore from the container 1 and additional material such as fine coke or coal from the container 2 are crushed in stone breakers 3, 4 ground fine in mills 5, 6 and fed into a measuring and mixing apparatus 7, from which the material is fed into wagons which are passed through an ante-chamber 8 into a tunnel furnace 9. The furnace is heated in the middle directly by electric resistances so that the material passing through is raised to a temperature of 650-950‹C. and then gradually cooled to about 50‹C. before the wagons enter the cooling chambers. Hydrogen from an apparatus 12 for producing pure hydrogen is led into a container 13 and thence in measured quantities into the furnace 9 where it flows towards the chamber 8. Used gas is withdrawn by a compressor 14 through a cooler and dryer 15 and compresses it in a separator 16 in which the carbonic acid in the gas is liquefied and drawn off into steel bottles 17. The puxified gas containing carbon monoxide and lighting gases is mixed with fresh .hydrogen from the container 13 and circulated through the furnace. Wagons pass through the chamber 10 and are unloaded by a combined magnetic separator and unloader 18 and the spongy iron is transferred through an enclosed shoot filled with a protective gas, e.g. carbon dioxide from the bottles 17, into presses 20 and formed into briquettes with the aid of a binder and pass into the store 21 from which they are fed into electric or other furnaces 23 where the iron is purified or converted into steel. Deoxidized iron shot or other refining or alloying materials such as ferro-chromium, ferro-manganese, nickel or silicon may also be fed into the furnace from a store 22. After casting into moulds, the iron or steel may be worked, while hot, in cogging mills 24. The iron shot may be deoxidized in the tunnel furnace with the ore.

Abstract: 891,931. Power measurement. SANGAMO WESTON Ltd. May 1, 1958 [May 8, 1957], No. 13953/58. Class 37. The apparent power (volt-amps) supplied by a transformer 10 to a three-phase balanced load A, B, C is measured by deriving a first current corresponding to the sum of the currents in lines A-A, B-B by means of a transformer 14, 17, 21 and a second current corresponding to that in line C-C by means of an air-cored transformer 20, it being proved mathematically in the Specification that portions of said first and second currents flow in phase in a temperature sensitive resistance 25, so that the current through this resistance will give an indication of the total current taken by the load. The resistance 25 will emit heat in proportion to the square of the current which effect can be used to give a visual indication of the current.

Title: Improvements in alternating current electric traction equipments
Inventor: BROWN JAMES KINGHORN
IPC: B60L9/12
Filed: 1955-05-16
Abstract: 827,722. Control of D.C. motors. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. May 14, 1956 [May 16, 1955], No. 14107/55. Class 38 (3). [Also in Group XXXV] The voltage supplied to a D.C. traction motion M from an A.C. supply through a transformer having secondary winding S and a rectifying arrangement comprising two or more anode-cathode paths in parallel, is varied on load by changing from one transformer tap to another, by means which includes depressing the anode volts of one path below that of the other to divert the current from one anode to the other. In the circuit of Fig. 1 the two paths are between main and auxiliary anodes A, C of a rectifier with a common cathode K. The motor M receives the algebraic sum of the voltages across part of the secondary winding S of the supply transformer from one of the taps 1, 2, 3 which may be distributed non-uniformly and part of the secondary winding SA of an auxiliary transformer whose primary winding PA is connected through reversing switch R and reactance TR to the taps on secondary winding S. The changes between the positions in which the supply is taken from taps 1, 2, 3 to provide the coarse adjustment of motor voltage, are made by appropriate operation of switches 1-3, 2a, 3a and Y. In changing from tap 1 to tap 2, the voltage supplied to the primary winding PA is first varied in known manner by sequential operation of switches 30-35 to increase the voltage at anode A until the voltage developed by winding SA is about half that between taps 1 and 2. Connection is then changed from tap 1 to tap 2, auxiliary anode C being momentarily supplied with the full voltage of tap 2 by closure of switch 2a, and switch R being reversed so that at the end of this step the voltage at anode A is little changed. Switch 2a is then opened and the load current again carried by anode A. The rise in volts to the motor while C carries current is only momentary. The voltage across primary PA is then reduced in steps by operation of switches 35-30 until the voltage at A is that at tap 2. The switching sequence for these and subsequent steps is given in a chart, Fig. 3A (not shown). Alternatively, the variable voltage supplied to winding PA may be derived from an induction regulator. The mercury arc rectifier may be replaced by ignitrons with or without exciter electrodes, or by semi-conductor rectifiers such as germanium or selenium rectifiers. The conductivity of the rectifiers may be controlled by the introduction into the rectifier circuit of a voltage from an auxiliary transformer, Fig. 4 (not shown).
