IPC: B21B45/00
Filed: 1969-09-18
Abstract: 1,270,868. Rolling. J. FROHLING, [trading as JOSEF FROHLING]. 18 Sept., 1969 [23 Sept., 1968], No. 46144/69. Heading B3M. [Also in Division G1] Electrical signals representative of the thickness and hardness of a metal strip 1 are converted by an hydraulic valve 11 into pressure fluctuations which are transmitted by pipes 12, 12a to hydraulic cylinders 13, 13a and pistons 14, 14a. A rack 15 connected to the pistons is thereby displaced, the displacement being transferred by a gear rim to a cam 16. The cam controls the pressure with which a backing roll 17 of a rolling mill presses on to the work roll 18 engaging the metal strip. The signals are derived from measuring and control apparatus (see Division G1).

Abstract: 1,208,360. No break supply systems. SIEMENS A.G. 27 Sept., 1968 [30 Sept., 1967], No. 46166/68. Heading H2H. An installation comprises a source of alternating current RST, rectifier 3, a D.C. to A.C. converter 5 having its input side connected to the output side of rectifier 3 to receive power from it, the two forming a static frequency converter 2, a rotary dynamo electric machine 8 which is coupled to a flywheel 10 and is connected to the output side 3a of rectifier 3, and a motor 7, the arrangement being such that when a load 1 is connected to the output side of the frequency converter 2, the input side of the rectifier 3 is being fed with alternating current from source RST and machine 8 is running, a brief reduction in the voltage on the input side of rectifier 3 results in the machine 8 acting as a generator, temporarily supplying the D.C. to A.C. converter 5. As shown 4 is a smoothing arrangement, and machine 8 is a synchronous rotary generator coupled to an asynchronous motor 7 and generator 8 is connected to output side 3a through a rectifier 9. Both rectifiers 3 and 9 may be controllable. The frequency of the output current of frequency converter 2 may be adjustable. Rectifier 9 may be a bridge rectifier constructed with thyristors. In a second arrangement, Fig. 2 (not shown) rectifier 9 is eliminated and machine 8a is a D.C. generator coupled to a synchronous or asynchronous motor. When the generator has been run up to speed, the motor may be de-energized and the generator may operate as a motor supplied from rectifier 3 until it is caused to operate as a generator due to a drop in voltage at the busbars RST.

Title: Process for roasting iron sulfide materials
IPC: C01B17/52
Filed: 1965-11-08
Abstract: In the process of roasting iron sulphides according to Specification 917,480 (wherein said sulphides are roasted in suspension under such conditions as to produce magnetite and sulphur vapour formed is converted wholly to SO2 after separation from the magnetite), hematitic or magnetitic iron oxide cinders or ores are added to the sulphides to be roasted up to a limit where the exothermic reaction ceases to be self-maintaining. Any arsenic, lead, and antimony contained in the hematitic or magnetitic iron oxide charge is driven off, and the roasted product is separated from it simultaneously with the sulphur. Dust-like cinders remaining in the roaster gases after separation of the major proportion of the cinders are separated and returned to the fluidized bed. Part of the oxygen for the roasting operation is supplied in a shaft above the bed, whereby the temperature can be held higher in the shaft than in the bed.  The roasting operation may be effected in the shaft.

A magnetic layer 30 may be added. The magnetic wires used may be beryllium copper, coated in a magnetic field with a single domain thickness of Permalloy to give a circumferential easy axis. The wires are insulated by a thermoplastics dip. Some of the wires may lack the magnetic coating to act as noise cancelling dummies. The memory plates may be stacked to give a three dimensional store, Figs. 7-10 (not shown), preferably with built in sense, select and drive circuitry.

Title: Fluid switch apparatus
IPC: F15C1/04
Filed: 1963-12-05
Abstract: 994,101. Controlling fluid flow. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 5, 1963 [Dec.10, 1962], No. 48027/63. Heading G3H. A fluid switch for gas or liquid and suitable for use in binary computors has a nozzle 15 for a power stream which may be directed to either of a pair of outlets 17, 18 under electromagnetic or fluid control. A wall 22 is set back from the nozzle 15 so that the power stream is normally drawn towards that wall by the creation of a low pressure region and flows to the outlet 18. This flow causes a flexible strip 23 of magnetic material anchored at its lower end, to bend so that it lies approximately parallel to the wall 22. If now an electromagnet 30 is energized to attract the strip to the position shown the power stream will be switched to the outlet 17 until the electromagnet is deenergized. The power stream can also be deflected by the application of a fluid pulse to a control nozzle 19. This will cause the stream to switch to the outlet 17 and the strip 23 to straighten until the pulses ceases, when the stream will revert to the outlet 18. The free end of the strip 23 may coact with electric switch contacts. The electromagnet has non-magnetic tips 31 to prevent attraction of the strip 23 by residual magnetism.

Title: Improvements in and relating to the control of supply in d.c. electric circuits
IPC: H02P7/29
Filed: 1962-12-20
Abstract: 963,092. Control of D.C. motors. K. JONES. Dec. 20, 1962, No. 48246/62. Heading H2J. A motor M is energized when a signal from pulse generator PG renders silicon controlled rectifiers SCR1-SCR3 conductive. Capacitor CX is charged from transformer secondary winding TS1 through diode D5, the amount of charge being dependent upon the current passing through transformer primary winding TP. When a further signal from pulse generator PG renders rectifier SCR4 conductive, the capacitor discharges through inductor L1 and rectifiers SCR1-SCR3 which are rendered non-conductive, the rectifier SCR4 becoming non-conductive automatically when the discharge current decreases. The frequency of the pulses from the generator PG is continuously variable to control the average motor current by modifying the number of power pulses per unit time. Section A of the pulse generator controls the firing of rectifiers SCR1-SCR3, whilst section B controls the rectifier SCR4. Transistors Tr1 Tr2 are rendered conductive when transistor Tr5 conducts, capacitor C2 cutting off the transistors Trl, Tr2, when fully charged. This condition continues until the charge on capacitor C2 leaks through transistor Tr5 which is controlled by potentiometer P1 when voltage is supplied from transistor Tr6 from capacitor C4. The output voltage is supplied through resistors R1, R2, R3, to the gate terminals of the rectifiers SCR1-SCR3. Transistors Tr4 conducts when a pulse is fed through capacitor C3 until the charge on capacitor C4 is dissipated, whereupon transistor Tr3 conducts and transistor Tr4 is cutoff, a pulse being fed to rectifier SCR4 through capacitor C5 and diode D1. A pulse cannot be generated by section A of the pulse generator until transistor Tr4 has become non-conductive. Adjustment of potentiometer P1 controls the pulse repetition rate. In a modification, the potentiometer P1 is replaced by a cell whose resistance varies in accordance with the amount of incident light, Fig. 3 (not shown). Transistor Tr7 responds to the temperature of rectifiers SCR1-SCR4 to render transistor Tr8 conductive and reduce the pulse frequency when the rectifiers tend to become over-heated. Secondary winding TS3 detects the motor current and charges capacitor C7 through diode D4. When the voltage across capacitor C7 causes Zener diode DZ to break down and reduce the pulse frequency. A time delay circuit C6, R6, associated with transistor Tr6 controls the rate of acceleration when starting the motor, a diode D3 allowing rapid discharge of capacitor C6 for quick reduction of pulse frequency. Diode D2 permits controlled acceleration to be introduced after the motor has reached a predetermined speed. When starting, slight movement of the potentiometer P1 is required before contactor S2 is closed. Diode D6 limits the back e.m.f. of the motor, whilst diode D7 forms a discharge path for the contactor coil. Specification 949,160 is referred to.
