Title: Improvements in or relating to signal storage devices for statistical machines
Inventor: DAWSON ERIC
Filed: 1955-03-07
Abstract: 769,805. Mechanical data storage apparatus. POWERS-SAMAS ACCOUNTING MACHINES, Ltd. Feb. 17, 1956 [March 7, 1955], No. 6694/55. Class 106 (1). Signal storage.-A signal storage unit for a statistical machine comprises a series of signal storing and transmitting elements 3, Figs. 1, 3, independently settable to a set position and mounted for lengthwise movement relative to each other and a bail 18 common to all the elements to effect lengthwise movement of any element set. The unit is controlled e.g. by a card reading means acting through solenoids 11. The elements 3 are slotted and mounted on a rod 4 being spring loaded into the lower position. A setting piece 7 for each element 3 is pivoted on the rod 4 and swingable against the action of a spring 12 by the associated solenoid 11 acting through a cable. The setting piece 7 is held in the setting position by a latch 14 which engages over a flange 9. The element 3 is connected to the setting piece by a spring 8 so that when the setting piece is operated the element 3 swings anti-clockwise to position a hooked end 17 over the bail 18. The bail 18 is mounted on arms 20 which can be connected to a cyclically-moving actuating member 24 as shown in Fig. 4. The pin 22 on arms 20 engages in a slot in member 24 and is normally engaged by a hook 23. The hook is displaced out of operating position by a plate 32, operable by a cable 30, which is latched in the disabling position by a latch 36. This suspends cyclic operation of the bail 18. The hook is allowed to return to operative position when the latch 36 is tripped through cable 40. All setting pieces 7 are allowed to return to unoperative position by tripping the latches 14. This is effected by a bar 42 which is swung anti-clockwise by a link 48 connected to arms 20. By this means, all the setting pieces are restored to normal position after each operation of bail 18. Any element 3 in the set position is raised upon actuation of the bail 18 so as to engage a corresponding cable 29.

Title: An improved electrical system for controlling the feed to a reeling motor in installations for the treatment of strip material
IPC: B65H23/18
Filed: 1951-03-22
Abstract: 705,179. Control of D.C. motors. LAURENCE, SCOTT & ELECTROMOTORS, Ltd., and LANGHAM, E. M. March 24, 1952 [March 22, 1951], No. 6902/51. Class 38(3) The speed and torque of a series motor M driving a drum upon which is wound strip material after the material has been annealed or otherwise treated is varied in predetermined relation to the strip speed to maintain approximately constant tension of the strip, or, alternatively, when a motor other than the reeling motor is used to maintain approximately constant strip tension, to provide substantially constant strip speed irrespective of build-up of the reel. The motor is supplied through a variable voltage transformer Tn which provides a voltage proportional to the linear speed of the strip and is connected to transformer Tt having a transformation ratio proportional to the square root of the tension of the strip. A voltage in accordance with the product of the strip speed and the square root of the tension is thus supplied through resistor Rn and rectifier X to the motor, a transformer T supplying compensation for the drop in the rectifier. The motor is either connected to a high voltage D.C. source Vd through resistor R, or the rectifier is connected to a high voltage A.C. source Vc through resistor Rc, in order to provide the motor with an additional torque compensating for frictional losses. The value of the resistor Rn is made a function, preferably linear, of the speed, the adjusting arms S, S2, of the transformer Tn and the resistor being simultaneously adjustable. This provides satisfactory operation at reduced powers. The resistance Rn may be replaced by a grid-controlled mercury arc rectifier.

Title: Method and apparatus for relaying television-type signals over long distances
IPC: H04N5/38
Filed: 1956-03-05
Abstract: 793,332. Television. HAMMOND, J. H. March 5, 1956 [March 9, 1955], No. 6916/56. Drawings to Specification. Class 40 (3). Television signals are transmitted over long distances with the aid of a radio carrier by a method in which they are first recorded and then played back at a reduced speed so as to reduce the signal bandwidth and permit the use of a relatively low-frequency carrier, e.g. 25 Mc., suitable for long-distance transmission. A converse recording and play-back process is employed at a receiver to restore the signals to their original form, when they are then retransmitted for local use by a normal relatively high-frequency, e.g. 50 Mc., television carrier. The invention is characterized by the use of a plurality of television signals, two as described, which, after reduction in bandwidth by the recording and play-back process, are transmitted simultaneously on the same carrier by a multiplex process, specifically amplitude and phase modulation in the described case of two signals. The two signals may represent separate programmes, or may be obtained from one programme by dividing the record in half timewise before playing back at reduced speed. This latter feature is used to avoid increasing the transmission time of a programme, since playing back a full record at half speed, say, doubles the transmission time. The recording is effected magnetically on tape as described, although reference is also made to the use of kinematograph film recording. Associated sound signals may be transmitted by a second multiplex radio transmitter or telephone lines. Reference is made to the use of the invention with colour television signals.
