Abstract: 1473197 Power converters FERRANTI Ltd 21 Oct 1975 [23 Oct 1974] 46896/74 Heading H2F A power converting system comprises a switching transistor 15, a transformer 12 for storing energy from an input power supply when the transistor is conducting and for transferring energy to a load 28 when the transistor is non-conducting, and comparators 21, 32 for controlling the transistor in accordance with the level of current flow to and from the transformer. A D.C. source is connected to terminals 10, 11 and a reference voltage is supplied to an input 22 of the comparator 21. When the current flowing through the transformer primary winding 13 causes the voltage across a resistor 18 to exceed the reference voltage, the comparator 21 supplies an output via a NOR gate 24 to block the transistor 15. The energy stored in the transformer is then discharged through the load until either a load voltage comparator 36 detects that the load voltage has fallen below a reference voltage or the load current comparator 32 detects that the load current has fallen below a reference value whereupon the output of the comparator 36 or 32 switches on the transistor 15 via the NOR gate 24. In a modification, Fig. 3 (not shown), the output of the transformer is isolated from the input and the outputs of the comparators 32, 36 are supplied to the NOR gate via an opto-electric isolator. In Fig. 4 (not shown), the D.C. output of the transformer is converted to A.C. by a thyristor or transistor bridge circuit.

Abstract: 1,114,383. Circuits employing bi-stable magnetic elements. VYZKUMNY USTAV MATEMATICKYCH STROJU. 8 Nov., 1965, No. 47182/65. Heading H3B. [Also in Division G4] A counter comprises in each stage first and second indicating cores such as 10, 11, a forward count core 12 and a backward count core 13. Assuming in the three-stage counter shown that the second stage is operative then core 22 or 23 is set and cores 20, 21 set and reset alternately to clock pulses F, E on leads 42, 41, respectively, whereby lamp 28 is maintained substantially constantly alight by induced pulses in a circuit including gated transistors 24, 25. When a subtract pulse P1 is applied to lead 51 then a pulse B on lead 55 occurs with the next F pulse and lasts longer so that it prevents core 20 setting. B is succeeded by a pulse A on lead 54 which prevents setting of any cores in the first and third rows. Simultaneously with the beginning of A a shorter count pulse D on lead 57 clears any of the cores in the third and fourth rows, in this case core 22, whereupon its associated transistor 26 pulses the first and third cores to the right and the second and fourth cores to the left, namely 30, 32, 11, 13. In this case 30 and 32 are inhibited by A so that only 11 and 13 set, so completing the operation of subtracting one. In similar manner addition is controlled by a pulse C on lead 56 so that cores 11, 13 are inhibited and cores 30, 32 set. A simpler unidirectional counter is described with reference to Fig. 3 (not shown). The counter may be arranged in decimal form with several denominations.

Filed: 1974-10-31
Abstract: 1486788 Television UNIVERSITY OF WESTERN AUSTRALIA 31 Oct 1974 [31 Oct 1973] 47258/74 Heading H4F A picture transmission system incorporates random or pseudo random scanning means. A Pseudo Random Number Generator 20 in the form of a shift register, feeds a stream of pseudorandom binary digits to X-shift register 21, Fig. 1, and Y-shift register 23. The registers are serially connected and each accepts eight random binary digits, the D-A converter stages 25, 26 produce analogue signals corresponding to the numerical value of the binary signals held in the registers, which control the position of the spot in a flying spot scanner 27. The spot is focused through transparency 29 on to a detector 30 the output of which is applied to a video amplifier 31. The output of amplifier 31 is applied to a modem 22 together with the current random bit entered in the most significant X register position for RF transmission 32. At the receiver Fig. 2 a modem 35 similar to that in the transmitter derives a clock signal from the incoming signal and applies it to serially connected X- and Y-shift registers 39, 40. The video and random bit information are separated at 38 and applied respectively to a display device 43 and registers 39, 40. D-A converters 41, 42 produce the scanning spot control signals as above. No synch. is required. The contents of the X and Y registers are shifted one place to the right for each scan point losing the least significant Y bit and injecting the next random binary digit in the most significant X bit position. On commencing reception the bit contents of the receiver's registers will not correspond to that of those in the transmitter but after 16 point scans (i.e. when the first random bit reaches the least significant Y bit position in the transmitter and receiver) the registers will be in agreement rendering a synchronous display from then on. In a further embodiment, Fig. 3 (not shown), a scanning standard converter is provided in which a line sequential scanning is converted to random scanning by the use of a three dimensional store (49) into which the video information is written, reading of the store being controlled in a random manner. The scan co-ordinates are derived in the same way as those in the previous embodiment. The device affords transmission bandwidth reduction and secret operation.

Abstract: 1,193,230. Colour television; semi-conductor pulse circuits. GENERAL TELEPHONE & ELECTRONICS LABORATORIES Inc. 11 Oct., 1968 [12 Oct., 1967], No. 48394/68. Headings H3T and H4F. Relates to a single gun cathode ray tube for a colour television receiver in which the direction of the electron beam is adjusted by means of a grid structure 13 to scan the correct one of a triad of colour phosphours in the form of strips on the face 12 of the tube. The grid is arranged as two sets 14 and 15 of wires, parallel to the direction of the colour strips, such that between terminals 26 and 27 there exists a capacitance C G , shown in Fig. 2. The invention lies in providing a colour switching circuit 16 which applies a stepped waveform between sets 14 and 15, the waveform being synchronized by pulses from the horizontal scan generator 20 such that the beam is deflected once every horizontal line on to a new colour strip. Fig. 2 shows a circuit 16 according to the invention wherein switches S 1  to S 3  are normally off. A pulse from generator 20 during a first horizontal retrace period switches S 1  on and charges up C G  through an inductor L to a potential 2E. S 1  is then switched off at the end of the pulse and C G  remains charged until a further pulse during a second horizontal retrace period momentarily switches S 3  on such that C G  is charged up in the opposite direction to a potential 2E in the manner of a tuned circuit formed by the inductor and C G  in series. During a third horizontal retrace period S 3  is momentarily switched on to discharge C G  through a resistor R, after which the cycle repeats itself. Hence three different deflection levels, one for each colour Red, Green and Blue, are obtained between sets 14 and 15. Figs 4 and 5 (not shown) illustrate two practical embodiments of the circuit of Fig. 2 wherein S 1  to S 3  are replaced by transistors in Fig. 4 and thyristors in Fig. 5.
