Patent GB-1102258-A (GB)
Title: Data communication systems
Inventor: HELM HARRY ARTHUR
IPC: H04J3/06
Filed: 1965-07-28
Abstract: 1,102,258. Electric digital multiplexing device. WESTERN ELECTRIC CO. Inc. 28 July, 1965 [28 July, 1964], No. 32160/65. Heading G4A. [Also in Division H4] A time division data transmission system comprises a plurality of sending stations each connected to a linear sequential encoder, responsive to a binary " 1 " from its sending station to generate a unique characteristic digital word of the same size as the words of the other encoders, each of the words being linearly independent, and a modulo 2 adder connected to the output of each encoder for adding the words produced and transmitting the result to a receiving system. The receiving system comprises a series to parallel converter to which the word is applied and a set of linear decoders for providing decoded signals to a receiving station. Transmission system.-The sending stations 10 1  to 10 6  are each connected by AND gates 30 1  to 30 6  to the encoders which comprise a set of delay units 21, 22, 23, 24, 25 and OR gates 26, 27, 28 to produce a unique six-bit digital word when a binary " 1 " is applied to their input. (In the case of encoder 20 1  the word is 111010 in 20 6  the word is 111001). A zero input produces a zero output. The six-bit words are then added modulo 2 i.e. a " 1 " is produced for an odd number of " 1 " inputs and a " 0 " for an even or zero number of " 1 " inputs. The six-bit sum is then sent to the receiving system. Receiving system (Fig. 1B, not shown). At the receiving station the six-bit word is applied to a series of delay units 50 to 55 and thence via AND gates to a series of decoders 60 1  to 60 6  comprising modulo 2 adders, which produce the original applied " 1 " or " 0 which then reaches receiving stations 70 1  to 70 6 . Theory.-The six, six-bit words produced by the encoders can be written as the columns of a matrix (P). Since the words are linearly independent an inverse matrix (P)<SP>-1</SP> can be obtained. The positions of " 1's " in each column of the matrix determine whether a link is made between AND gates 90 to 95 and adders 65 1  to 65 6 . Thus a set of signals x 1 -x 6  forming a column matrix (M) is multiplied by (P), transmitted, multiplied by (P)<SP>-1</SP> arid emerges as (M). An example is given in the Specification. The two systems are maintained in synchronism by means of synchronizing sources 39, 36. It is stated that if synchronism is lost then each receiving station will receive an unintelligible, garbled message, rather than a message intended for another station. Redundant parity checking bits may be included in the encodergenerated words to provide a transmission error detecting and correcting capability.

Title: A method of improving the dust collecting efficiency of wet electrostatic precipitators
IPC: B03C3/68
Filed: 1962-08-22
Abstract: 990,200. Electrostatic precipitators. METALLGESELLSCHAFT A.G. Aug. 22, 1962 [Aug. 23, 1961], No. 32321/62. Heading B2J. [Also in Division H2] Space charge which inhibits the efficiency of an electrostatic precipitator is reduced by means of an automatic voltage regulator which allows arc discharge to continue for a period before control is effected by reducing the voltage, the voltage being cut off for a period if the discharge continues despite the control. As shown in Fig. 1, potential for the precipitator 1 is supplied by a rectifier 2 powered from a transformer 3 the primary of which is driven from a potentiometer 10. The current taken by the primary of transformer 3 is monitored by current transformer 4 and transformer 15 which supplies a discriminating relay set 16 which is shown in detail in Fig. 2. The input to the relay set 16 is rectified to set up control voltages on the resistor chains r2 and r3, and r14 and r15. Should the voltage on chain r2, r3 rise above the rated value thyratron P1 fires to extinguish normally conducting thyratron P2. Slugged relay dl in the anode circuit of P2 releases after a given time to drive motor 9, Fig. 1, by way of control circuit 8 to set the potentiometer 10 to a value to reduce the current supplied. Should the current drawn by the precipitator rise to a value greatly in excess of the rated value the voltage on chain r14, r15 rises to fire thyratron P3 and extinguish normally conducting thyratron P4. Slugged relay d2 in the anode circuit of P4 releases, after a given time during which the consequent heavy discharge is allowed in the precipitator, and by means of control circuit 8 causes relay 12 to disconnect the supply to potentiometer 10. After a further fixed interval the relay 12 reconnects the supply with tubes P3, P4 and relay d2 restored to normal so that heavy discharge in the precipitator is repeated for as long as d2 takes to release a second time. This process is repeated a given number of times after which relay dl is allowed to control potentiometer 10 to reduce the supplied voltage. Switches bl, b2 are provided with a stabilized voltage supply from tubes P5, P6, in order to test the operation of tubes P1, P2, and P2, P3, respectively. The primary of transformer 3, Fig. 1, has an associated pulse transmitter 5 and a variable resistor 6 in circuit the functions of which are not disclosed. The discharge electrodes are preferably such as to have corona discharge points directed perpendicular at the collecting electrode and being spaced at regular intervals of 10 cms. The electrodes are 25 cms. apart.

Abstract: 1,038,304. Transistor switching circuits. SPERRY GYROSCOPE CO. Ltd. Sept. 8, 1965 [Aug. 10, 1964], No. 32550/64. Heading H3T. [Also in Division G4] A warning device comprises an oscillator and a loud-speaker arranged to given an audible warning, and a time delay circuit which energizes a pilot circuit at a predetermined time after the audible warning commences. The arrangement is suitable for use in the presence of inflammable gases, being arranged to operate from a low voltage, and being enclosed in a flame-proof casing. Completion of a low voltage 50 c/s. supply circuit to terminals 1, 2 produces a partially smoothed D.C. output from rectifier 3 which energizes an oscillator comprising transistors 6, 7 and saturable transformer 8 to produce a square-wave output signal modulated with the unsmoothed ripple component. The impedance of the supply connected to rectifier 3 is made high by resistor 4 and the load on the supply due to the oscillator causes the D.C. output from rectifier 3 to be about 8 v. Capacitor 19 charges towards this value until the Zener voltage of diode 20 is overcome and transistor 21 switches on, switching off transistor 23, and switching on transistor 26 to apply a voltage to a pilot circuit connected to terminals 27, 28. Upon transistor 21 becoming conductive transistor 12 also cuts off and oscillations cease. The reduction of the load on the power supply due to the oscillator switching off allows the output from rectifier 3 to rise to about 14 v. aiding the switching of transistors 23, 26. A further time constant circuit including capacitor 33 is provided to prevent transistor 26 from becoming conductive immediately should the oscillator fail to operate.
