Title: Improvements in or relating to the magnetizing roasting of oxidic iron ores
IPC: C22B1/14
Filed: 1962-09-26
Abstract: Iron ore in which the recoverable iron is present substantially in trivalent form is subjected to a reducing treatment in a rotary kiln using as reducing agent a solid finely divided petroleum coke which has been produced by coking heavy fuel oil in direct contact with the ore in the heating zone of the kiln.  The fuel oil may be mixed with the ore before the latter is fed into the kiln.  The rotary kiln may be equipped with jacket burners operated with an excess of air so that the quantity of oxygen supplied is at least sufficient for combustion of the volatile constituents escaping during the coking of the fuel oil.  The jacket burner nearest the charging end may receive the maximum excess of air while those nearest the discharge end receive the smallest excess of air. The fine grain portion of the ore may be fed to the kiln at a point situated after its charging end and at this point additional heavy fuel oil corresponding to the fines added may be admixed prior to introduction.  The reducing zone may be free of any stirring device. If desired, some of the outlet gases may be returned to the delivery end of the kiln.

Class 34(2) A centrifugal clothes &c. drying machine has means for ensuring that the drum driving means and the braking means are not effective concurrently and that the lid cannot be opened without operating the brake. As shown, two brake blocks 25, bearing at diametrically spaced points on the underside of the drum pulley 19, are carried in a U-shaped frame 27, Fig. 2, on a lever 29 pivoted on a rubber bush 33. A rod 41 extends upwards from the end of this lever to a rocker 43, which, when the lid 13 is closed, is tilted in a clockwise direction by a lid locking pin 44 to hold the brake blocks clear of the pulley. When the lid is opened, the rod 41 is allowed to drop and the blocks 25 are pressed against the pulley by springs 35. The lever 29 also carries a plate 38 by which a plunger switch 37 is closed, to run the electric driving motor 20, when the lever is in its raised position and the lid is closed. By this means, the motor can only be switched on when the brakes are released and vice versa. In a modification, Fig. 5 (not shown) the brake lever is actuated by cam means by rotating a vertical rod, the top of which carries a radial handle which lies over the lid to prevent it being opened when the motor is switched on.

Abstract: 982,476. Automatic speed control. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 23, 1963 [Oct. 18,1962], No. 37312/63. Heading G3R. [Also in Division H2] An electric motor 18 which drives a rolling mill is coupled to tachometer generator 42, a voltage reference being obtained from potentiometer 28 to energize pattern winding 31 and control winding 32 of a pulse modulator associated with controlled rectifier 36 and ignition 37. The armature voltage of the motor increases linearly until a base speed is reached, whereupon the armature voltage remains substantially constant and the field is weakened. The field winding 20 is connected to magnetic amplifier 22 sensing the counter E. M. F. through windings 70, 74, by noting the difference between terminal voltage and IR drop. The amplifier 22 obtains a reference in accordance with motor speed through generator 42 and winding 62, the counter E. M. F. being proportional to speed for operation below the base speed, and the reference signal being limited by circuit 66 so that the counter E. M. F. is kept constant above the base speed. The armature voltage regulation is quicker in response that the field regulation. Before a strip enters the mill, relay 56 closes contact 60 so that a threading speed reference is obtained from potentiometer 28. After the strip passes through the front end of the mill, contact 60 is opened and contact 58 closed to provide normal running speed. After the strip leaves the mill, hot metal detector 54 senses the absence of the strip and closes contact 52 for a period determined by timer 55 to introduce dynamic braking and to provide the threading speed reference signal. The braking circuit through resistor 48 is opened by a current-sensing relay 39. Current limit control is afforded by winding 46 in the pulse modulator 34.
