Title: Improvements in and relating to grid-controlled rectifier systems
IPC: H02M1/04
Filed: 1946-01-04
Abstract: 610,072. Converting; inductances. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Jan. 4, 1946, No. 378. [Class 38 (ii)]  A circuit by which the control electrodes of a rectifier are energized from a three-phase source, comprises a D.C. controlled variable reactor in each of the three phases, a saturable reactance and a capacitor being connected across each pair of the three, circuit terminals connected to the electrodes. To illustrate the principles of the invention a single-phase circuit is shown in Fig. 2 in which rectifier grids are energized from an A.C. source, a D.C. controlled variable reactor X is connected between the source 1 and output terminals 4 of the circuit, and a saturable reactance device SR which may be a square wave transformer as described in Specification 466,282 and condenser C are connected in parallel across the output terminals. In the three-phase case a variable reactor is connected in each phase and a saturable reactor and condenser are in parallel between each pair of the phases. It is shown by analogy with the supply to a synchronous condenser that the phase of the grid impulse is varied by varying the saturation of the series reactor X. To obtain phase shift of more than 90 degrees several control circuits may be connected in tandem. The singlephase case, not within the invention, is illustrated in Fig. 4 (not shown). To reduce the minimum inductance value of the variable reactor X a condenser may be connected in series. To reduce the 5th and 7th harmonics in the control circuits which may shift the peaks, each reactor winding may be split into two parallel groups of zig-zag windings with 30 degrees phase shift between their fluxes, Fig. 6. The parallel groups are divided into two series sections I, II, on which the D.C. windings are so arranged that no A.C. is reflected into them. The Figure accompanying the Complete Specification shows a construction in which the twelve reactors are combined into one structure, but with the phase positions 0 and 30 degrees instead of Œ 15 degrees as in Fig. 6. The D.C. windings are omitted but the arrows show the direction of the D.C. flux. The invention is described as applied to the twelve phase rectifier circuit in which the load is balanced between two six-phase groups which forms the subject of Specification 610,073, Fig. 8 (not shown).

Title: Binary integer divider
IPC: G06F7/52
Filed: 1958-01-07
Abstract: 879,538. Digital electric calculating-apparatus. MONROE CALCULATING-MACHINE CO. Jan. 7, 1958 [Jan. 7, 1957], No. 672/58. Class 106 (1). Apparatus for obtaining the integral part of the number of times an integer value is contained in a quantity represented as a binary series-mode pulse train includes an adder/subtractor having a delay connected between its output and one of its inputs. As shown, Fig. 1, an input binary number A is fed to a terminal 11 of an adder/subtractor 10, the output C at terminal 13 being fed back through a delay 14 of D pulse times to form a second input B at terminal 12. It is shown in the Specification that when 10 is a subtractor, C = A/(1 + 2<SP>D</SP>) and when 10 is an adder, C = A/(1 - 2D). By taking D = 1, 2 and complementing if necessary division by five or three is obtained. This applies only when the dividend A is an integral multiple of the divisor. If this is not so, a dividend K is applied to the input, Fig. 2, in a word time of J pulses where J is suitably chosen so that 1 + 2<SP>J</SP> is divisible by the required divisor, the dividend being applied twice successively so that N = (1 + 2J)K is effectively applied, the required integral part of the quotient being obtained at the output during the time of the second input entry. As shown in Fig. 2, for division by three, a delay 24 of one pulse time is included and the number J is odd. The second input entry is obtained by using a delay 25 of J pulse times and the required output is obtained by opening a gate 26 in the second input entry time. Arrangements are described for effecting division by five and for effecting division by three or five alternatively (Figs. 3 and 4, not shown).

Title: An improved device for recognising patterns of electrical pulses
Inventor: INGHAM WILLIAM ELLIS
IPC: G06V10/75
Filed: 1961-01-10
Abstract: 1,006,995. Automatic character reading. ELECTRIC & MUSICAL INDUSTRIES Ltd. Jan. 10, 1962 [Jan. 10, 1961], No. 956/61. Heading G4R. In character recognition apparatus the circuit which identifies the character from binary signals derived from sensing the character consists of an array of bi-stable cores which are set by a " learning " process so that each combination binary input signal will give the corresponding output. Learning.-In the learning process the input signals are applied in parallel to terminals A1-A5 and stored in triggers B1-B5. A set of gates C1-C5 are enabled by a " 1 " stored in the associated trigger and a set of gates D1-D5 are blocked by a " 1 " and enabled by a " 0 ". Pulses applied at W pass through Or gates Y1-Y5 and those of gates C1-C5 and D1- D5 which are enabled on to lines F0-F9 each linked with all the magnetic cores of a co-ordinate array of cores. The odd numbered lines F1, F3, F5, F7 and F9 are selected when a " 0 " is stored in the corresponding trigger and the even numbered lines when a " 1 " is stored. The output lead to be associated with the combination stored is chosen by marking the appropriate row lead J0-J9. Where both the column and row leads are marked the core switches. Recognition.-The input combination is again applied to the triggers B1-B5 and a pulse is applied to terminal U to start a pulse generator R. Pulses from the generator are applied to a shift register, the stages being set and reset in succession to enable gates C1, D1, C2, D2 and so on. The column lines F0-F9 are thereby energized or not in succession according to the condition of the associated triggers B1-B5. Where a core is switched the energization of the column lead resets it to produce an output pulse on a row lead H0-H9. The pulses occurring on each lead pass through Or gates N0-N9 to counters P0-P9 each of which therefore counts the number of digits in the input pattern which match with the pattern stored in the associated row of cores. The pulses are also fed back to reset the cores on the J leads. A perfect match would give a count of five in the corresponding counter and an output pulse would be given indicating the re-coded value of the input. In practice for character recognition there will be more than five digits and some digits will probably be incorrect due, for example, to defective printing. It is therefore necessary to determine the best match, i.e. the highest count in the counters P0-P9. For this purpose, if no counter gives an output at the end of the entry of the input pattern, clock pulses are entered into all of them from a source S. The first counter to overflow indicates the characters. The number of added pulses necessary may be counted and the character rejected if they are too many.

Title: Improvements in and relating to automatic steering apparatus for dirigible craft, such as ships
IPC: G05D1/02
Filed: 1925-08-01
Abstract: 265,529. Sperry Gyroscope Co., and Sperry, E. A. Aug. 1, 1925. Steering-gear. - Automatic steering-gear for ships and other dirigible craft comprises a master controller acting automatically or under hand actuation through an electric transmission system on the rudder. An additional hydraulic telemotor system may also be installed. The master gyro G has its movements transmitted to a repeater motor 1, Fig. 1, connected to the contact arm 4 of a master controller M, which co-operates with contact rings 24, 25, 40 geared to follow up repeater motors actuated by a transmitter 99 from the rudder gear. The controller M acts through a relay 91<1> to control a reversible motor 90" adapted to move the valve of a steering engine or the rudder direct, but preferably through a clutch 95. The master controller has means for cutting out the automatic control to allow for hand actuation of the master gear. as described in Specification 265,246, and means for providing slip or lost motion settings for " weather " and " telemator adjustment, " as described in Specification 214,215. In the preferred arrangement at the rudder, the reversible motor 90<11>, Fig. 13, with its magnetic brake 90<111> drives through worm gearing a shaft. 94, and thence through a clutch 95 is driven a shaft 96 that carries the pinion 98 for the follow-up gear 99 and also a pinion 100 that operates a rack 101 which is connected with the rudder actuating lever 106. The rudder can thus be operated by the motor 90<11> under automatic control of the repeater R, Fig. 7, or by hand control through the wheel 28. In addition the rudder lever 106 may be moved by telemotor gear 104 operated bv the pilot wheel 110 through the racks 111, the clutch 95 being rendered inoperative. Preferably the clutch has electric coils in circuit with the main motors, so that when the electric control is cut out or fails the clutch is de-energized and the hydraulic gear centralizes the rudder. A modification of the master controller consists in substituting a cam for the contact arm, which is on a shaft receiving all the controls combined to operate through differential gear, the contacts being on a lever rocked by the cam and adapted to co-operate with fixed contacts in place of the rings.
