Title: Improvements in and relating to electric motor control systems
IPC: H02P3/10
Filed: 1937-10-08
Abstract: 496,978. Master control of D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. Oct. 8, 1937, No. 27398. Convention date, Oct. 8, 1936. [Class 38 (iii)] Non-regenerative braking ; reversing.- A " plugging '' resistance inserted in the circuit of a motor when the supply connections are reversed is controlled by a relay connected across the motor armature and responding to a predetermined voltage, a rectifier being connected in the relay energizing circuit for rendering the relay ineffective during normal operation but permitting current to flow to the relay when the supply connections are reversed. Upon operation of a controller 22 to its first forward position, a forward contactor 13 connects the motor for forward operation, and interlock contacts energize a contactor 19 which cuts out resistance 16 from the motor circuit. Further movement of the controller energizes contactors 20, 21 under the control of relays 36, 37, to cut out accelerating resistances 17, 18. The energizing circuit for the contactor 19 includes normally closed contacts of a relay 23 which has its coil in series with a rectifier 24 across the motor armature, but the rectifier prevents response of the relay 23 to the increasing armature voltage. If the controller is moved to its second reverse position, the contactor 13 opens and a reverse contactor 14 closes. Moreover, the contactors 20, 21 insert the resistances 17, 18, and the resistance 16 is inserted by de-energization of the contactor 19. With reversal of the motor connections the coil of the relay 23 is energized and maintains the contactor 19 de-energized until the motor voltage falls sufficiently to cause the relay 23 to drop out, whereupon the contactor 19 is energized and the resistance 19 cut out. The motor then accelerates in the reverse direction and the rectifier 24 again prevents response of the relay 23 to the increasing armature voltage. Specification 450,790 is referred to.

Abstract: 1,130,584. Local copying by scanning; colour reproduction. WALL PAPER MFRS. Ltd. 9 June, 1966 [1 July, 1965], No. 27854/65. Heading H4F. In an arrangement of the kind described in Specification 1,013,423 in which a multi-colour original 16 is scanned by a photo-electric head 4 to produce signals which are applied to selective circuits 12 whereby a plurality of recording heads 6 are caused to produce recordings each corresponding to the existence of a different colour in the original, the original is provided with registration (and, if desired, identification) marks in one or both margins 9, 10 and a switch mechanism 7, 8 responsive to the position of head 4 is caused to actuate a relay 13, 14, 15 to disable the selective circuits 12 and substitute an amplifier 11, which is connected to receive a selected one of the photo-electric head signals, during the scanning of the margins, whereby the detection of a mark causes an identical signal to pass to all the recording heads 6 and identical marks to be produced in all the records. The marks in the original may be in black-andwhite or two contrasting colours. A more detailed circuit of a modified arrangement is described with reference to Fig. 2 (not shown). In this arrangement the change-over from selective circuits 12 to amplifier 11 is effected by biased diodes controlled by relay 13, 14, 15. Amplifier 11 is connected to the photo-multiplier in head 4 which responds to red light. Reference is made to the use of an arrangement where the original comprises a symmetrical pattern and in which the photo-electric head reverses its direction of scan half-way across the pattern. With such an arrangement a second (reverse) scanning of the margin of the original is unnecessary and may be suppressed by suitable switching.

Title: Improvements in and relating to communication systems particularly applicable to type-printing telegraph systems
IPC: H04L19/00
Filed: 1935-10-14
Abstract: 464,471. Type - printing telegraphy. CLAYTON, C. E. EVERY-. (Nationale Telephon-und Telegraphenwerke Ges.) Oct. 14, 1935, No. 28353. [Class 40 (iii)] The signal corresponding to a character comprises two groups of impulses those of the first group having setting values at the receiver of unlike magnitude while those of the second have the same setting values. The invention is described with reference to a type-printing system the receiver of which has a type wheel which is moved from its normal rest position in steps of decreasing magnitude by the impulses of the first group and subsequently in unitary steps by the impulses of the second group, all the impulses for the complete signal being of alternate polarity. Transmitter. Depression of the character key ST, Fig. 2, releases a pawl KN through a lever 72 to lock a code wheel SN to a ratchet ZN keyed to a constantly rotating shaft 60. Movement of the code-wheel SN actuates the signalling contacts SK and locks the keys ST by operating a lever 77 to move a locking bar 64. The lever 77 also opens contacts SKK to introduce an artificial line into the receiving relay circuit which is also affected by the transmitted impulses. Receiver, translating mechanism. The type wheel TR, Fig. 6, is carried on a shaft 90 the rotation of which is controlled by either of two double ratchet mechanisms DME EME depending on the position of a slidable sleeve 80 keyed thereto. The signal proper is preceded by two positive preparatory impulses which actuate the magnet U to set the sleeve 80 in the upper position and to move the pawl associated with the ratchet wheels DME to its starting position. The first group of impulses controls said pawl to allow the ratchet DME to advance amounts corresponding to 8, 7, 6, &c. units. A zero current space between the first and second groups is utilized to shift the sleeve 80 and divert subsequent impulses to control the ratchet EME which is subsequently allowed to advance the predetermined number of unitary steps corresponding to the second group of impulses. A final prolonged zero current period initiates the printing operation. Printing action and paper feed. The print. ing magnet DM, Fig. 12, operates the hammer DH and feeds the ratchet wheel 101 one step forward to move the tape P. Case-shift. The type wheel TR, Fig. 13, bears two rows of type, the hammer DH being shifted to co-operate with either by shift signals which move the type wheel to blank positions and with it discs Zi, Bu which control the position of a lever 106 adapted to shift the hammer DH to print the selected row of type. The shift signals are produced by specially provided keys on the transmitter keyboard. The line and control circuits are described in detail, Fig. 16 (not shown).
