Filed: 1930-10-29
Abstract: 360,652. Control of two D. C. motors. BRITISH THOMSON - HOUSTON CO., Ltd., Crown House, Aldwych, London, and GREEN, W. B., 47, Portland Road, Rugby. Oct. 29, 1930, No. 32542. [Class 38 (iii).] Two motors 4, 5 connected to winding drums for passing strip material to and fro through a rolling-mill are controlled in such a manner that their torques are in opposition and the motor with the stronger field winds up the strip causing the other motor to be rotated in opposition to its torque and thus produce a braking effect. The armatures are in series, thus the reverse rotation of one motor causes it to regenerate and boost the voltage across the motor with the stronger field. The direction of motion is determined by a drum controller 16 which connects the field windings of the winding motor so that the series field aids the shunt field and connects the field windings of the braking motor so that the series field opposes the shunt field, and moreover connects a rheostat 18 in the shunt field of this motor. The motors are fed from a constant voltage generator 20 in series with a variable and reversible voltage generator 21.

Patent GB-334270-A (GB)
Abstract: 334,270. Hamilton, R. M. March 4, 1929. Monogrammic signs.-A totals indicator for use in a totalizator comprises a monogrammic sign 11 adapted to display on a field of lamps or other elements a different numeral for each position of a multiple-contact control switch which is electrically actuated to keep step with the totalizing counter 12, a separate multiple-contact control switch being provided for each digit of the total to be displayed. The switches are interconnected so that the indication of unwanted zeros in front of significant figures in the total is avoided. Each totalizing counting unit 12 of the kind described in Specification 333,258, [Class 106 (i), Calculating &c.], has ten numeral transmission lines 13 connected to a bank of contacts 14 through the medium of relays 15 adapted to change a live " line 13 on the side 12 to a corresponding dead " line 13 on the side of the contacts 14, the line selected corresponding to the position of the counter. A contact member 16 having five arms is moved step-by-step over the contact bank 14 by a ratchet 20 operated by an electromagnet 17 through an interrupter contact 18, the ratchet moving a shaft 19 carrying the member 16 and also a number of similar contact switches 21 - - 26 which travel over contact banks 27 - - 32 and select the appropriate lamps on the sign 11 to form the required digit. The member 16 is thus rotated until it rests upon a contact of the bank 14 connected to a " dead " line 13. Fig. 3 shows the inter-connection of the corresponding contact members 21, 35, 36 of the separate multi-contact switches provided for the several digits of the total, each switch being controlled from the corresponding digit element of the counter 12.
