Title: Improvements connected with the control of a.c. commutator motors
IPC: H02P25/12
Filed: 1941-02-19
Abstract: 546,699. Controlling current commutator motors; transformers. SCHWARZ, B. Feb. 19, 1941, No. 2284. [Classes 35 and 38 (ii)] In a polyphase commutator motor, a magnetizing voltage component Ec, Fig. 1, leading the main secondary voltage E, by 90 degrees is introduced into the secondary circuit from the secondary winding St, Fig. 3, of a transformer provided with primary coils Pt, the connections of which to the supply are changed in accordance with a change in the direction of rotation of the motor. In a 3-phase stator-fed motor reversal is secured by interchanging two of the phases and at the same time Ec is reversed into the position E<SP>1</SP>c to preserve its leading character. An additional voltage Es opposing the main secondary voltage enables the centre point of the speed range to be shifted from the synchronous speed without overloading the double induction regulator used for speed control and remains unchanged on reversal. The resultant Ea of the two voltages must shift through an angle twice α on reversal, and in Fig. 3 this is done by the provision of two auxiliary windings 1, 2 which may be connected alternatively in zig-zag with the main primary windings 3, by reversing switch CS. When α a is 60 degrees the windings 3 vanish and windings 1 and 2 coalesce into simple primary coils which are cyclically interchanged, Fig. 5 (not shown). In a modification, Fig. 6 (not shown), delta-connected primary windings have alternative tappings for the supply connections. With a two-phase supply the secondary may be arranged to give two or three open phases. In the application to rotor-fed Schragetype machines with adjustable brushes, a frequency changer must follow the transformer so as to supply compensating voltage at slip frequency to the secondary circuit, which includes the stator winding as well as the rotor commutator winding. The frequency changer may have a commutator winding with tappings, or a separate tapped winding, connected through slip rings to the secondary of the compensation transformer ; its brushes are connected to the secondary circuit of the motor.

Title: Improvements in electromagnetic relays
IPC: H01H51/32
Filed: 1941-02-21
Abstract: 543,799. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., and SMART, N. C. Feb. 21, 1941, No. 2362. [Class 40 (i)] Apparatus for opening and closing a pair of contacts 10 in response to pre-determined code signals comprises a self-starting synchronous motor 1 which is unlatched by an initial impulse and runs through a half-revolution provided the subsequent impulses arrive at the proper times, the contacts being controlled by a cam 9. The action is governed by a cam-wheel 4 having two sets of teeth 12-20 and 32-47 for co-operation with the latching member 11 which is moved away from the cam-shaft at each impulse by a vibrating reed 28 tuned to the signalling frequency and controlled by the impulse-receiving magnet 24, 25. In the absence of signals, the motor, which is conveniently of the kind used in electric clocks, oscillates between narrow limits imposed by the engagement of the member 11 with the tooth 12 or 15 and that of a detent 21 with a notch 22 or 23 in the periphery of the cam-wheel. After the motor is released by the withdrawal of the member 11 at the first impulse, if the subsequent impulses do not conform to the pre-determiried code, the rotation is stopped by the engagement of the member 11 with a tooth of one set or the other, whereupon the motor reverses and returns to its starting position. By the provision of other reeds, and latching members for co-operation with further sets of cam-teeth, the apparatus may be made responsive to code signals comprising impulses of different frequencies.

Title: Improvements in or relating to the purification of hydrochloric acid
Inventor: VERGANO LAURENCE PETER
IPC: C01B7/00
Filed: 1961-01-20
Abstract: The hydrofluoric acid content of aqueous hydrochloric acid is decreased by contacting the HCl with silica containing water of hydration and precipitated from a silicate solution, or a precipitated water-insoluble silicate, insoluble in 30% HCl, for example barium silicate.  The HCl solution should be at least 30%, and may be contacted at ambient temperatures.  Sodium silicate solution is stirred into HCl and precipitated SiO2 is filtered off, washed, dried at not above 60 DEG  C., and packed into a column made of rubber-coated mild steel polyvinyl chloride, or polyethylene.  The HCl may be treated in two series-connected columns to decrease the HF to 0.002% or less.  Continuous operation may thus be effected by provision of three columns, one of which is being regenerated and recharged.  The HF absorption capacity of the precipitated siliceous material may be increased by boiling the SiO2 in the aqueous liquor from which it has been precipitated, or by passing steam through the column. Regeneration may also be effected by steaming or by suspension in water and boiling.  The Provisional Specification refers to the use of calcium silicate.  Specifications 822,494 and 823,677 are referred to.
