Patent GB-484637-A (GB)
Title: Improvements in and relating to the production of silicon iron
IPC: C22C38/02
Filed: 1937-05-27
Abstract: Silicon for use in the production of silicon iron is purified by melting it in a quartz crucible under reduced pressure to remove hydrogen.  If it contains oxygen and nitrogen, calcium or one of the rare earth metals, such as cerium, may then be added, the excess being distilled off.ALSO:In a process for producing silicon iron, particularly one containing approximately 3 to 5 per cent of silicon, the iron is first melted alone, then decarbonized by adding one or more readily reacting oxides, then, after removal of any undesired constituents which may have entered the melt, is deoxidized, after which the silicon is added to the molten iron, the whole of the operations being carried out in the aforesaid sequence and under reduced pressure.  Iron oxide or manganous oxide may be used for the decarbonization, the excess of manganese being in the latter case subsequently distilled off.  The deoxidation may be performed by a hydrogen atmosphere or by passing hydrogen through the melt; alternatively one or more metals of the second group of the periodic system, especially calcium or beryllium, may be added, the excess being distilled off.  One or more of the rare earth metals especially cerium may be employed for deoxidation, instead of, or in addition to hydrogen or calcium, the excess being distilled off.  Copper up to 1 per cent may be added.  The silicon may be purified before adding it to the iron, for example by melting it in a quartz crucible under reduced pressure to remove hydrogen.  If it contains oxygen and nitrogen, calcium or one of the rare earth metals, such as cerium, may then be added, the excess being distilled off.  In order to enable the additions to the molten iron to be made without breaking the partial vacuum, the substances to be added may be contained in a vessel disposed in the melting chamber and having a valve at the bottom which can be operated from outside.

Abstract: 529,206. Master control of D.C. motors. BRITISH THOMSON - HOUSTON CO., Ltd. May 24,1939, No. 15452. Convention date, May 25, 1938. [Class 38 (iii)] Braking.-To provide for the " inching of a hoist driven by a motor 10, in the lowering direction under heavy loading conditions, the coil 33 operating to release a friction brake is connected in series with the motor armature but in the first lowering position is shunted by a circuit including a non-inductive resistance 18. Thus on movement of the controller to its first lowering position to energize contactors 17 and 37 to connect the motor to the supply with its armature and field in parallel, the brake is released gradually and the controller may be returned to its off position before the brake is fully released. The shunt circuit for the coil 33 is controlled by a normally closed contactor 36, opened when the controller is in its second position. Two rheostatic braking circuits for the motor are provided one, including a resistance 35, controlled by the contactor 36, and the other comprising resistances 18, 22, controlled by the contactor 37, and the contactors 36, 37 are electrically interlocked so that the second braking circuit must be established before the first is interrupted, and the first re-established before the second is interrupted. On the case of failure of the second braking circuit the first is re-introduced. When the controller is returned to its off position and the motor disconnected from the supply a rapid application of the brake results from the opening of the shunting circuit across the brake coil 33.
