Title: A sequential timing device
IPC: B21B39/20
Filed: 1960-03-03
Abstract: 931,669. Sequential switching systems. KLOCKNER-WERKE A.G. March 3, 1960 [March 3, 1959; Sept. 26, 1959], No. 7600/60. Class 38 (4). [Also in Group XXXV] A sequential timing device comprises a plurality of electronic voltage-responsive devices such as thyratrons R1 to the grids of which two A.C. phase displaced voltages are fed, which voltages control the conducting period of the devices. The voltages are derived from a 3- phase network through a continuously rotated phase shifting transformer M, supplying another transformer Y having a number of secondary windings to which a plurality of transformers T1, T2 are connected. In the arrangement shown second thyratrons R2 are connected in reverse parallel. A plurality of third transformers T3 connected to the same anode supply as R1 can suppress the firing point of the thyratrons so that only a small part of one cycle can be employed. In another arrangement, shuntable rectifiers are connected in series with each thyratron to prevent the inductive or capacitive reaction of anode resistances Ra. The thyratrons may be replaced by bi-stable flip-flop circuits.

Title: Improvements in or relating to oscillator circuits employing transistors
Inventor: ATTWOOD BRIAN ERNEST
IPC: H03K3/30
Filed: 1961-03-02
Abstract: 896,024. Transistor oscillator circuits. MULLARD Ltd. March 2, 1961, No. 7649/61. Class 40(6). In a transistor relaxation oscillator of the type in which the frequency is determined by a capacitor, the frequency is stabilized against temperature change by a negative temperature coefficient resistor R3 in, the emitter circuit. In the blocking oscillator shown, regenerative feedback is provided by the coupling between windings Ll, L2. An increase in temperature causes an increase in base-collector current (I oo ), so that when the transistor is cut off the effective time constant of the base circuit becomes reduced. The reduction in the value of R3, however, causes Cl to change to a higher value when the transistor is conducting hence the change in frequency is minimised. The sawtooth waveform across Cl may be used as field deflection in a television receiver. Thermal runaway is prevented by the resistance of L2.

Title: Improvements relating to super-regenerative radio receivers
IPC: G01S13/76
Filed: 1946-03-16
Abstract: 609,576. Valve super-regenerative circuits. FERRANTI, Ltd., and WOOD, H. March 16, 1946, No. 8251. [Class 40 (v)] The invention relates to automatic constant sensitivity control arrangements for receivers of the type comprising a super-regenerative amplifier, a following amplifier and an intervening detector. The control voltage is applied to the grid of the super-regenerative amplifier and is derived from the anode current of the second amplifier, the mean value of which varies inversely with the random voltage fluctuations present in the receiver. In the Figure, valve 7 is a quench oscillator, valve 1 a super-regenerative amplifier and valve 61 a leaky grid detector combining the functions of detector and amplifier. The voltage across the cathode resistor 65 of the latter valve is applied through series connected resistor and inductor 43, 11 to the grid of the super-regenerative amplifier. Thus, when the sensitivity of the receiver increases an increase noise voltage is applied to the detector, the decrease in mean anode current which results, reduces the voltage across the cathode resistor causing an increase in the bias of the super-regenerative amplifier and thus a reduction of receiver sensitivity. Specifications 685,353 and 591,965 are referred to.

Title: Data transmission system
Inventor: DUUREN HENDRIK CORNELIS ANTHON
IPC: H03M13/51
Filed: 1970-02-20
Abstract: 1293812 Code conversion arrangements [NETHERLANDS POSTAL & TELECOMMUICATION SERVICE DIRECTOR GENERAL OF 20 Feb 1970 [25 Feb 1969] 8297/70 Heading H4P [Also in Division G4] A data transmission system for converting unbalanced binary coded signals into balanced binary coded words comprises means for converting each of five 5-bit signals into 6-bit signals such that the 6-bit signals have two "1" bits or three "1" bits, the signals having three "1" bits being transmitted normally whereas the signals having two "1" bits are transmitted normally or inverted and the word comprising two parts each of'which includes a parity bit ' such that the first part of thirteen bits has six 1" bits and the second part of nineteen bits has ten "1" bits. Each 5-bit signal is successivelv fed from an information source 1B, controlled by a clock pulse generator KPG, to a shift register ABCDE, a code converter CC and a "1" bit counter TA-TB-TC. When the register has recorded the signal a pulse PST causes a trigger S to send a signal to a register KK1-KK5 to place the trigger KK1 in the "1" state. The counter determines the number of "1" bits in the 5-bit signal and controls a trigger F which adds a "0" bit to the 5-bit signal if the number of "1" bits is two or three and a "1" bit if this number is one. The output of the counter is also fed via gates PK1-PK5 to a register TK1-TK5 which discriminates between signals-having two "1" bits and three "1" bits. The outputs of the register TK1-TK5 are fed to a trigger R and also to triggers X13 and X32 to determine the two parity bits of the word. The trigger R controls two sets of gates for each of the five 6-bit signals, such as gates 11-16 which transmit the signal normally to a register ST1-ST6 and gates 111-116 which invert the signal. The inversion or normal transmission of the signals is determined by two rules, one rule being applied to each part of the word. A pulse PTR transmits the contents of the registers ST1-ST12 and ST14-ST31 to registers X1-X12 and X14-X31 from which the information is shifted by pulses PX.

Abstract: 714,792. Lathe details. BECHLER, A. April 2, 1952 [April 6, 1951], No. 8445/52. Class 83 (3). Indexing mechanism for the tool turret of an automatic lathe &c. comprises a reciprocatory member operated by a first rotary cam member and means including a second rotary cam member rotatable with said first cam member for engaging said reciprocatory member with said tool-turret to impart to the latter the required indexing movement. The turret 2 carrying tools 3, Fig. 2, and rotatable in the machine frame 1 is provided with pins 32 protruding from the rear end, one for each turret station. The forked end 24 of a member 23, Fig. 1, engages each pin in turn as it comes into the position 32a and under the turret. This is effected by carrying the member 23 on a rod 14 reciprocated by an arm 10 from a cam 6 through a follower 9. The rod 14 slides at one end through a rotatable sleeve 15 to which it is keyed at 18. A collar 16, secured by a screw 17 to the sleeve 15, has a lever 22 attached through linkage 21 to a double crank lever 20, 20a, pivoted on a shaft 25 parallel to the turret axis. The crank arm 20a carries a cam follower which engages a second cam 7. The two cams are arranged on a cam shaft 4 which, in a known manner (not described), is given one complete rotation when an indexing operation is to be carried out. A third cam operates a double-armed lever 27 also pivoted on shaft 25; a locking finger 29 on the upper arm of this lever engages a notch 30 on the turret head when the latter is at an index station.

Filed: 1967-02-22
Abstract: 1,172,583. Traffic control systems. GENERAL SIGNAL CORP. 22 Feb., 1967 [28 Feb., 1966], No. 8473/67. Heading G4Q. In a traffic control system, a set of traffic lights controlled by a local timer, may be put under the control of a central station by coded information transmitted by the central station. As described, the information is in the form of positive and negative pulses and is applied to the input terminals 48, 49, Fig. 3, of the local controller. For local operation, the phases are switched by cam switches which are stepped by a motor 29 driving cams 18, 22. If a train of positive pulses are applied at terminal 48, the first one operates relays K1, K3, K4 to disconnect the stepping drive from the local motor, via contact 69 and connects it to the contact 70 of relay K3. Subsequent pulses then operate K1, K3 to step on the phases, relay K4 remaining held in by the charge on capacitor 56. If it is desired to omit some phases, a train of alternate negative and positive pulses are transmitted. In this case, the first negative pulse operates relays K2, K5, K6 to change to an all red phase via contacts 67, 72, 73, 74, 75, 76. Subsequent positive pulses operate as before to step on the cam switches although no change from " all red " occurs. Termination of the negative pulses releases relay K6 and the lights take up the phase appropriate to the new cam switch setting. During the time the lights are in the " green artery " phase (i.e. as shown), the A.C. on switch 66 is applied to line 77 and is fed back to the central controller, Fig. 2 (not shown), as a check signal to operate a relay (I). The positive and negative pulses are produced by the actuation of further relays (P and N) in the central controller.
