Title: Improvements in the production of alloy steel
IPC: C21C5/00
Filed: 1963-08-14
Abstract: A process for making an alloy steel having an alloying content of over 5% comprises oxygen top blowing of the liquid crude iron, which comprises 20-75% of the total charge, in a crucible under a highly basic slag rich in ferric oxide to give an intermediate product having a phosphorus content of less than 0.025%, the slag is then removed and the non-oxidizing solid alloy carriers are added, blowing is continued to cause liquefaction finally the oxidizing alloy carriers (containing carbon and silicon) are added and the blowing is completed, under a basic slag having a Ca O/SiO2 ratio of at least 2. 5 or a CaO + MgO/SiO2 ratio of at least 1.5, until the carbon and silicon introduced with the alloy carriers have been removed.  The slag is then treated with a reducing agent to remove the slagged alloy constituents and, after removal of the reduced slag, any remaining alloying elements of high quality are added to the crucible. The non-oxidizing alloy carriers may consist of Ni or Mo alloys and chemical heat carriers, such as FeSi, may be added therewith.  The second blowing stage is preferably stopped when an appropriate carbon content has been achieved.  The oxidizing alloy carriers disclosed are Cr and Mn alloys and the reducing agent for the slag may be Al, Si, or Ca-Si.  After addition of the high quality alloy carriers slag formers, e.g. lime and ingot iron, can be added to make a fining slag.

Patent GB-876050-A (GB)
Title: An ignition revolution counter
Filed: 1959-09-25
Abstract: 876,050. Electric motors. SCHLAICH, R., [trading as MOTO METER-HERMANN SCHLAICH]. Sept. 25, 1959 [Sept. 26, 1958], No. 32636/59. Class 35. [Also in Groups XXXVII and XXXVIII] Relates to a revolution counter for internalcombustion engines in which a synchronous motor 1 is driven in synchronism with ignition impulses from contact breaker 52 and has its speed detected by an eddy current tachometer 14, 15. When the engine starts, the tachometer needle 19 is in the zero position and a cam 55 causes contact 54 to be earthed, so that relay 44 is energized and a battery 38 sends current through motor winding 7 to urge rotor 3 into a defined initial position. In this position, cam 12 permits closure of contacts 10 whereby the motor starting winding 5 is intermittently energized from generator 37 and the motor is accelerated due to repulsion between like poles on the stator and rotor, the inertia of the rotor causing continued rotation until its position in relation to poles 4 is such that further repulsion increases the initial rotary motion. Auxiliary poles 8 are excited by winding 5 and ensure that the rotor always starts in the same direction. When the needle 19 is deflected from its zero position, the cam 55 releases contact 54 and allows relay 43 to move to its second position whereupon the motor winding 7 is energized with synchronizing pulses from the switch 52. The speed of the motor eventually corresponds with the frequency of the ignition impulses and further acceleration due to the starting winding is prevented owing to the more powerful effect of the winding 7. If the engine speed exceeds an upper limit, a cam 22 earths contact 23 to energize magnet 13, so that contact arm 36 is held away from the cam 12 and the motor starting winding 5 is disconnected. The magnet 13 is de-energized when the speed drops below a given minimum value and contact 23 is opened by insulated cam 21, the starter field winding being then re-energized. Above the upper speed limit, the motor is driven exclusively by the field winding 7 which is energized by the synchronizing pulses. If the rotor falls out of step, the starting winding comes into operation and restores the motor to synchronous speed.
