Title: Improvements relating to electrically driven clocks
IPC: G04C15/00
Filed: 1934-12-11
Abstract: 447,080. Electricity supply; motors. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S. BAXTER, F., and WORSTER, N., Edgware Road, Cricklewood, London. Dec. 11, 1934, No. 35543. Addition to 395,695, [Group XVIII]. [Classes 35 and 38 (iv)] Substituting sources in series.-In the arrangement described in the parent Specification for supplying a clock motor with intermittent direct current of suitable frequency on failure of the ordinary alternating current supply means are provided for simulating the effect of alternating current more closelv than does an intermittent current. For this purpose the motor, besides the alternating- current winding, is provided with two windings one of which carries the intermittent current and the other a direct current opposed to the intermittent current, the two fields being so proportioned that the resulting field resembles that due to the alternating current. The Figure shows a circuit for producing this effect. Alternating current is supplied by a transformer g to the motor winding d and through a rectifier m to an electromagnet l. A battery u supplies current directly to a motor winding c and, through a vibrating contact r, the period of which is controlled by a spring to be equal to that of the alternating current, to a motor winding c. The windings band c are normally cut off by a switch controlled by the electromagnet 1, but on failure of the alternating current the switch closes and puts the windings band c in circuit. The windings b, c and d may act on the same motor or the windings band c may act on one rotor and the winding d on a second rotor on the same shaft, or two separate motors geared together may be employed.

Title: Continuous casting control system using vessel pressurization
IPC: B22D11/20
Filed: 1970-07-23
Abstract: 1317750 Continuous casting USS ENGS & CONSULTANTS Inc 23 July 1970 [25 July 1969] 35818/70 Heading B3F [Also in Division G3]  In a continuous casting system in which molten metal flows from the bottom of a vessel into a mould, the level in the latter is maintained constant by automatic control of the withdrawal rate of the casting in dependence on the level, and a valve controlling the supply of pressure gas to the vessel is automatically controlled in dependence on the volume cast to maintain a constant effective head in the vessel. In Fig. 1, a vessel 2 containing molten metal is closed and evacuated through a conduit 10 and then suplied with gas through a conduit 70 from a pressurized source 68 to maintain a constant effective head when a gate 8 is opened and the metal flows out to continuous casting moulds such as 14. The level in mould 14 is automatically maintained constant by a detector 20 which controls a speed regulator 24 for a motor 26 driving pinch rolls 16 withdrawing the casting. The signal from a tachometer generator 28 representing the rate of withdrawal is applied to a potentiometer 34 set to correspond with the cross-section of the casting so that a signal representing the volume cast is combined in an integrator 38 with similar signals from potentiometers 34<SP>1</SP>-34<SP>111</SP> representing volumes cast in other moulds (not shown). The output of integrator 38 is modified by a diode function generator 42 to correspond to the pressure required in the vessel to maintain a constant effective head. This required pressure signal is compared with an actualpressure signal from the transducer 48 and any difference is effective through a proportional controller 58 and actuator 64 to adjust a valve 66 so that the required pressure is obtained. Signals representative of the casting rates are also applied to potentiometers 36-36<SP>111</SP> so that deviations of the average rate of casting from a desired rate set at 44 are applied through a PI controller 46 to controller 58 to modify the pressure in vessel 2 so that a desired rate of casting is maintained. If the pressure in vessel 2 should exceed a value determined by a potentiometer 52, a relay 56 is operated to disable control of valve 66. When gate 8 is shut, a switch 60 operates to close valve 66. In a modification, the signal representing volume cast is derived from load cells responsive to the total weight of vessel 2 and a potentiometer set to allow for the tare weight.

Title: A Method of Purifying Copper
IPC: C22B9/05
Filed: 1966-08-10
Abstract: 1,160,984. Purifying copper. PHELPS DODGE CORP. Aug.10, 1966 [Aug.10, 1965], No.35899/66. Heading C7D. Copper is purified by treating it in a hydrogen atmosphere to dissolve H 2  therein in an amount sufficient to reduce the oxygen present and provide a dissolved excess which will cause effervescence of the molten copper during the subsequent reduced pressure treatment. The copper (e.g. electrolytically refined copper) is preferably heated in H 2  but may be heated and melted in an inert gas prior to the hydrogen treatment. A suitable apparatus for performing the vacuum treating step of the process is described in Specification 1, 160, 985.

Title: Safety means for rotating projectiles
IPC: F42C15/22
Filed: 1961-10-05
Abstract: 931,348. Ammunition fuzes. NORDISKA ARMATURFABRIKERNA A.B. Oct. 5, 1961 [Oct. 6, 1960], No. 35933/61. Class 9 (1). A fuze for rotatable projectiles, operating when impact ruptures a diaphragm 3 and so releases a striker 4 to drive a firing pin 1 against a percussion cap 2, is provided with safety means comprising a slide 5 immobilizing the pin 1 during transport and handling. A spring 7 holds the slide 5 in the locking position. The position of the centre of gravity of the slide is such that, the centrifugal force developed on firing the projectile maintains the slide in the locking position. To arm the fuze, a ball 10 is provided which moves into a bore 11 in the slide and so alters the position of the centre of gravity that the centrifugal force causes the slide to move until a bore 6 is coaxial with the pin 1. To increase the safety margin before arming takes place, the ball 10, instead of being housed in an inclined passage leading to the bore 11 as in the prior art, is housed in a space 12. Initially, the ball 10 sets back due to inertia into a bore 13. When acceleration ceases the ball 10 moves into the space 12 and due to centrifugal force and friction against the inclined walls of the space 12 eventually moves into the bore 11 and unlocks the slide 5.
