Title: Improvements in or relating to data signalling systems
Inventor: COUSINS JOHN RICHARD
IPC: H04L1/16
Filed: 1962-05-31
Abstract: 1,032,032. Telegraphy. GENERAL ELECTRIC CO. Ltd. May 31, 1963 [May 31, 1962; Jan. 3, 1963], Nos. 21097/62 and 391/63. Heading H4P. [Also in Division G4] The invention provides an error-detecting telegraph system in which errors are corrected by repetition. The characters are transmitted in groups, and any group which is repeated is preceded by synchronizing signals and by signals indicating the ordinal number of the group (group count). A cyclic counter which controls transmission has its capacity temporarily increased to accommodate the sync. digits. If the group count at the receiver does not agree with the count of the repeated group resynchronization is performed manually. In the absence of any error, 5-bit characters are read from a punched tape into a temporary store. A horizontal parity bit is added, and the 6-bit signal passed serially to the output line and in parallel to a 20-signal main store. The 5-bit signals also operate a vertical parity counter, and after 9 characters have been read from the tape the 5-bit vertical parity signal is passed to the temporary store and a horizontal parity bit added. The group as transmitted thus contains ten 6-bit signals. At the receiver, the signals pass to a temporary store and are checked for horizontal parity before being passed to a main store which can hold ten 5-bit signals. A vertical parity check is made, and the signals then read from the store to control a tape punch. If a parity error is discovered a signal requesting repetition is sent to the transmitter which, prior to repeating the group of signals, sends four 6-bit signals. These signals are used for checking synchronization at the receiver, and also indicate the ordinal number of the group being repeated, this number being derived from a group counter which is stepped upon the transmission of each group. The sync. checking signals are compared at the receiver digit by digit with a stored check signal. Any discrepancy causes the receiver's signal counter to be reset and the group is again repeated. If the digit synchronization is correct an odd/even signal from the transmitter is compared with a corresponding signal at the receiver. This signal indicates whether the repeated group is odd or even-numbered. This signal may be of the expected category and yet the group counts be out of step by an even number of steps so the ordinal numbers are now compared. If these differ the system is shut down and a warning actuated. The transmitter and receiver are then resynchronized and the receiver tape spliced so that any signals punched during resynchronization are deleted.

Title: Improvements in and relating to proportional control
Inventor: OUGHTON HARRY GEORGE
IPC: G05D23/19
Filed: 1960-06-16
Abstract: 921,435. Automatic temperature control. FOSTER INSTRUMENT CO. Ltd. June 1, 1961 [June 16, 1960; Oct. 14, 1960], Nos. 21187/60 and 35273/60. Class 38 (4). A system for stabilizing the temperature of a furnace employs a bridge comprising two potentiometers 11, 14 the voltage applied to which is increased as the bridge becomes unbalanced. The slider 10 of potentiometer 11 is moved by a servomotor 4 in a self-aligning potentiometer circuit 2, 3, 5 in accordance with the actual furnace temperature, measured by a thermocouple 1. The desired temperature is set on slider 15 of the other bridge potentiometer 14. The bridge is supplied from a transformer winding 12 through a further potentiometer 50 whose slider 52 is linked with slider 10 while its supply point 51 moves with slider 15. It is arranged that, when the bridge is balanced, the slider 52 coincides with the point 51 of winding 50 so that the voltage applied to the bridge is at a minimum and equals that between points 54 and 55 of the transformer winding. Increasing unbalance of the bridge in either direction due to movement of either slider 10 or 15 results in the addition of an increasing portion of the voltage between 53 and 54 of the transformer. The winding 50 may be linear, logarithmic or exponential. The output of the bridge is compared with that from a second bridge comprising potentiometers 18, 22 and the resultant used to actuate a voltagesensitive relay 32, 34 controlling a fuel valve servomotor 16, which is supplied from a source 35. The second bridge is concerned with setting the fuel valve to which one of its sliders, 17, is connected. The other slider, 23, is driven by a motor 24 when a contact 27, linked through actual furnace temperature, closes with either 26 or 28 connected to the set temperature control. Thus, when the furnace temperature deviates from the set value, current through relay 32 due to the unbalancing of bridge 11, 14 causes the fuel valve motor 16 to run in a correcting direction. This displaces slider 17 of the second bridge, and unless a correction be applied by moving slider 23, as described, the system would come to rest with an out-ofbalance voltage from the second bridge, necessitating an output from, and hence a misalignment of, the first bridge. Known changes in fuel requirements of a furnace may be anticipated by displacing 23 by a hand control 23a, thus deliberately creating misalignment conditions. The voltage for the second bridge is derived from a transformer winding 30 and is hand adjusted by potentiometer 31 which is said to effect the range over which the fuel valve is automatically controlled. An arrangement is mentioned in which the potentiometer 22 is replaced by a set of four variable resistors adjusted differentially.

Abstract: 517,121. Transformer arrangements for electricity supply. BRITISH THOMSONHOUSTON CO., Ltd. July 18, 1938, No. 21269. Convention date, July 17, 1937. [Class 38 (iv)] In order to avoid flickering of incandescent lamps where the load includes motors, arc welders and other heavy loads on the supply, the lighting and power loads are drawn from the two sides of a three-wire circuit supplied by the secondary of the power transformer and the neutral common to the two loads includes an impedance' equal in value to the equivalent primary circuit impedance with respect to the secondary current taken by a least one of the loads. By these means, the power components of the two load currents flow in opposite instantaneous directions in the common neutral conductor and the lighting circuit is unaffected by heavy variations in the other load circuit. The mathematical considerations underlying the invention are set out in the Specification as shown in Fig. 1, the secondary 12 has the neutral 13 connected to its mid-point with the imped- .ance Z3 in its circuit, and.the lamp load 14 is, connected between the neutral and one outer and two induction motors 16 between the neutral and the other outer. As applied to a three-phase transformer, in one form shown in Fig. 3, the three-phase induction motor load 16 is connected across, the delta-connected secondary N2 which has its phase windings extended by windings N1 to afford a supply for the lamp load, inductances Z3 of the required value being connected in the common neutrals.
