Abstract: 840,772. Driving chains. SCHMIDT, G. Sept. 7, 1956, No. 27452/56. Class 24. A driving chain, connecting two pairs of toothed conical wheels of an infinitely variable gear system, comprises multiple-plate links in each of which is flexibly mounted a transverse two-part bolt having at each end a tooth which engages in the radial teeth of the conical wheels: As shown, the teeth 4, 41 are formed on bolt parts 5 and 6 having engaging male and female end portions. Plates 7 and 8 support the bolt in a housing 9 which is mounted in apertures in the plates 10 forming the chain links. Spring sleeves 14 prevent the bolt parts 5 and 6 from sliding sideways out of the plates 7 and 8 during free running of the chain.

Title: Analog-to-digital-converter
IPC: H03K7/08
Filed: 1973-06-12
Abstract: 1436851 Analogue to digital converter GENERAL ELECTRIC CO 12 June 1973 [21 June 1972] 27986/73 Heading H3H An analogue to digital converter comprises a voltage to frequency converter 14 to which the unknown voltage V x  and a feedback voltage are fed in opposition, a phase detector 18 determining the phase difference between the output of converter 14 and a reference oscillator 20, in the form of a train of duration (mark/space) signals, a low pass filter 26 which generates the feedback analogue voltage from the mark/ space signal and a counter 30 which counts clock pulses for the duration of the duration signal to provide the digital output. As described, the unknown voltage V x  is supplied via resistor R i  and after subtraction of the feedback voltage via resistor R j , provides an input V Q  to the voltage controlled oscillator 14. The output frequency is divided by N at 16 and the pulses are squared and fed to the phase detector 18. The output of an oscillator 20 controlled by reference voltage V R  is divided by M and fed to the phase detector 18. The phase detector output after filtering is fed back to complete the phase locked loop which alters V Q  until the phase detector input frequencies are the same. The phase difference duration pulses gate pulses from oscillator 20 to a counter 30, which may be preset to a desired count and the count, which is regenerated for each phase detector duration output may be transferred to a holding register 32. The converter may be produced as an integrated circuit, the frequencies of the oscillators being different to prevent interaction.

Abstract: 503,126. Cathode-ray tubes. PYE, Ltd., and LIEBMANN, G. Aug. 25, 1937, No. 28007/38. Divided out of 503,074. [Class 39 (i)] Electrons from the cathode pass successively through two electrodes each with several perforations and through a further electrode which is maintained at or near the potential of the cathode or final anode of the tube and which has an aperture electronoptically reproduced on the fluorescent or other screen. Defocusing effects of the perforations are thus avoided and a straight or other desired control characteristic obtained. An indirectly heated cathode 10, Fig. 2, held in an annulus 13 as described in Specification 503,125 is close to a modulating electrode 26 and a first anode 27 both having similar and correspondingly placed perforations 33, Fig. 3. Electrons passing through these perforations are focused by an electrode 28 and coil 29 towards a small aperture in a stop 32 in the final anode of the tube, and this aperture is focused on to the screen 25 by coils 30. The final anode is formed partly by a wall coating 23. Magnetic shields 31 may be arranged between the coils. The electrodes are spaced as described in Specification 603,074. In a modification, the electrodes 26, 27 each have a single aperture covered with gauze, the stop 32 has an internally stepped aperture to assist concentrating the electrons through it and is at cathode potential, and an electrostatic lens formed by second and third anodes produces on the screen an image spot of the same size as the aperture in the stop. The second anode is tubular with perforated diaphragms and the third anode is a wall coating. Electrons may be concentrated on to the stop electrostatically by short cylinders or discs of decreasing diameters and increasing potentials. Electrode dimensions and voltages are specified.

Abstract: 1392165 Automatic exchange system; D.C. data transmission STANDARD TELEPHONES & CABLES Ltd 14 June 1973 28285/73 Headings H4K and H4P In a 4-wire, VF exchange system having at least one substation which emits a timing signal for the purposes of digital data transmission between substations, the data is amplitude modulated on to the timing signal. From the timing station 3 in Fig. 1, clock timing pulses (Œ6v relative to zero) are supplied via pad 6 and hybrid transformer 7 to a two wire Go path 2, 1, 2 extending to a data sending station 4 which is also a speech station. After amplification, the clock pulses are recovered for use by synchronous circuits connected to terminal 12 and also by modulator 13 to which data signals are fed via terminal 14. The hybrid transformer 10 ensures that the modulated signals are supplied to the Go path in phase opposition to the clock pulses. The data signals are extracted by a circuit 9 in the timing station. Fig. 2 depicts the return path situation wherein the timing station (referenced 4) includes a modulator 13 which is coupled to the path via a simple matching transformer 18 while the receiving station (referenced 3) includes a similar coupled demodulator 9. Fig. 9 (not shown), depicts the case where the Go and Return paths both have modulator/demodulator coupled thereto via hybrid transformers so that data signalling capacity is increased. The data bit rate must be an even submultiple, i.e. ¢, “, of the clock bit rate. Fig. 3a depicts the clock pulse waveform, Fig. 3b a data signal waveform where "1" i.e. mark, pulses are positive and "0" i.e. space, pulses are negative and Fig. 3c an amplitude modulated resultant waveform. A demodulator 9 comprises two independent diode/transistor/Zener diode circuits for recovering respectively a timing waveform (Fig. 5a, not shown) and a data waveform (Fig. 5b, not shown) A modulator 13 incorporates a complementary pair of transistors in shunt with a pair of Zener diodes across the power supply. For mark signals the transistors conduct alternately to permit the full value of the supply to be connected to line whereas for space signals the diodes conduct alternately so as to connect a lower voltage level to line (Fig. 6, not shown). A pulse discriminator comprising a resistor/diode/ capacitor network, (Fig. 7, not shown) may be connected in series with the timing pulse recovery amplifier 11 (Fig. 1) so as to reject modulated signals occurring as crosstalk.

Abstract: 1,213,546. Protective arrangements. COUTANT ELECTRONICS Ltd. 16 June, 1969 [14 June, 1968], No. 28384/68. Heading H2K. A stabilized power supply, e.g. for integrated semi-conductor circuits, includes a series regulating element, e.g. a transistor VT1, an output capacitor C and a semi-conductor controlled rectifier SCR connected across the output terminals O/P and arranged to be fired to discharge the capacitor should the output voltage exceed a predetermined value and to provide a path for fault current should the element VT1 become faulty, e.g. to blow a fuse. To protect against over-voltage conditions which would not cause sufficient current to flow to blow the fuse, the firing of the rectifier is arranged to control, or be accompanied by the control of the element VT1 to cause it to pass little or no current. In the figure, the rectifier anode is connected to the positive drive source of a transistor VT2 controlling the transistor VT1 so that when the reactifier SCR fires it diverts the base current of the transistor VT2 so that the transistors VT2, VT1 cease to conduct. In a modified arrangement a second controlled rectifier may be used to divert the transistor base current and to provide the drive for the main controlled rectifier, Fig. 3 (not shown).
