Title: Method of producing dense iron and iron alloys directly out of oxide ores
IPC: C21B13/12
Filed: 1926-03-26
Abstract: 252,677. Cornelius, R. G. E. May 26. 1925, [Convention date]. Extracting. - In a method of producing iron having a low percentage of oxygen and/or gas directly out of ores, in which the ore in a finely divided state is mixed with finely divided carbonaceous material, and, if desired, some other reducing agent, and formed with a suitable binding agent into briquettes or lumps and the charge reduced and melted while floating on a slag bath in an electric furnace, the ore or one of the ores used is an iron ore containing oxides of vanadium or titanium or both. In order to obtain an acid slag during the melting process substances such as quartz, sand &c. are added to the charge. If the ore used contans phosphorus and/or sulphur. lime, dolomite, &c. are added to obtain instead a basic slag during the melting, and the iron &c. produced is separated from the slag and treated with an oxidizing slag; the slag formed, if vanadium ore is, used, will contain the greater part of the vanadium and the iron or alloy is then purified in another furnace. In preparing the charge for the furnace, the ore and the reducing agent should ,be ground to such an extent that at least 75 per cent of the grains so produced will pass through a sieve having 200 meshes per sq cm.

Title: Improvements in or relating to electric power supply arrangements including one or more vapour electric arc rectifiers
IPC: H02M7/15
Filed: 1952-04-01
Abstract: 733,159. Rectifying. GENERAL ELECTRIC CO., Ltd., DALE, S. H., and THOMPSON, W. G. July 1, 1953 [April 1, 1952], No. 8291/52. Class 38 (2). So that a load may be shared in predetermined proportions by a discharge-type rectifier 1 connected in parallel with a dynamo-electric machine 2, 4 between A.C. supply 5 and D.C. load circuit 3, the output of the rectifier is controlled in dependance on the output of the machine. The grid impulses of the six-phase rectifier 1 are controlled at 7 from a valve amplifier 10 which receives a signal from a shunt 9 in the output of the machine which may be a motor generator set. The relative proportions of load may be varied by a manual setting 8 of the grid impulse controller 7. To prevent current from the rectifier being fed to the motor generator set when this is accepting regenerated power from the load circuit, the rectifier grids may be blocked when the current through shunt 9 reverses. Where the rectifier has an interphase transformer the acceptance of current from the rectifier at no load prevents a voltage rise in the D.C. load circuit. The shunt 9 may be replaced by a bridge arrangement of saturable reactors, or the signal current to the amplifier 10 may be derived from the difference between the outputs of D.C. current transformers connected respectively on the D.C. sides of the rectifier and machine. A magnetic amplifier may replace the valve amplifier. A limit may be set to the current supplied by the rectifier.
