Patent GB-591765-A (GB)
Title: Modulator system
IPC: H03C7/02
Filed: 1943-12-03
Abstract: 591,765. Electric transmission lines ; modulating. STANDARD TELEPHONES & CABLES, Ltd. Dec. 3, 1943, No. 20394. Convention date, Aug. 6, 1942. [Classes 40 (iii) and 40 (v)] Relates to modulating devices of the kind described in Specification 540,871 for radio beacons, in which a rotating slotted condenser plate 40 varies the resonance frequency of a quarter-wave-length section 20, 21 which is electrostatically coupled to a transmission line 10, 11 so as .to block the transmission of current of the resonance frequency in the manner described in Specification 517,935, and comprises means for broadening the responses so that the blocking effect may persist in spite of frequency-drift or of modulation of the kind described in Specification 563,076. The production of standing waves between the source and the coupled section is eliminated when the coupled section is detuned. To broaden the response, the coupling between the quarterwave-length section 20, 21 and the line 10, 11 is increased, without a dangerous decrease in the spacing between them, by enlarging the conductors 20, 21 and so shaping them, for instance as hemi-cylinders, Figs. 1, 2, or as quarter-cylinders or flat strips (Figs. 3, 4, not shown) that they cut an extended area of the electrostatic field and so increase the capacity between the coupled section and the line. In order that the coupled section may not increase the sending-end impedance by setting up standing waves when the coupled section is detuned, the coupled section is half a wave-length long, but one quarter-wavelength is open-circuited at one end 30, 31 and short-circuited at the other by a bar 32, while the other quarterwave length is short-circuited throughout at intervals as by bars 34, 36. Wave-reflections in the line 10, 11, due to change of impedance adjacent to the ends of the coupled section cancel one another when the section is detuned so that standing waves are avoided, while if the section is resonant to the transmitted current the two quarter-wave-lengths have dissimilar effects and transmission is blocked. The section 20, 21 may be mounted so that it can be adjusted in relation to the line 10, 11 by means of screws 28, 29, Fig. 2. The inner surfaces of the section may be provided with a material having a large dielectric constant.

Patent GB-1142658-A (GB)
Title: Apparatus to convert a pure binary code into a binary-decimal code
IPC: H03M7/12
Filed: 1966-05-10
Abstract: 1,142,658. Radix conversions. INTERNATIONAL STANDARD ELECTRIC CORP. 10 May, 1966 [13 May, 1965], No. 20650/66. Heading G4A. In apparatus to convert from pure binary to binary-decimal code, pulses are routed via logic circuitry to a binary counter and to a binarycoded-decimal counter, under control of a comparison unit comparing the binary input with the count of the binary counter. An input binary number E is compared with the contents of a binary counter Z in comparators Vgl1 (for the four lowest order bits) and Vgl2 (for the other bits). If either comparator indicates non-equality, unit ST resets to zero all the counters Z, DZ, HZ1, HZ2, and starts clock pulse generator TG. If comparator Vgl2 indicates non-equality, gate Tor routes the clock pulses through OR gate 02 to the 2<SP>2</SP> stage of counter Z and to the 2‹ stages of counters HZ1, HZ2. On every third pulse counter HZ2 causes AND gate U2 to increment the units decade D2(1) of binary-coded-decimal counter DZ and to zeroize counter HZ2. On every fifth pulse counter HZ1 causes AND gate U1 to increment the tenths decade D1 (0À1) of counter DZ (except that every sixth pulse to this decade is suppressed at PU) and to zeroize counter HZ1. If comparator Vgl1 only indicates inequality, gate Tor routes the clock pulses to the 2‹ stage of counter Z and via a delay V3 and unit PU to the tenths decade D1 (0À1) of counter DZ. AND gate U2 is blocked. Any carry from stage 2<SP>1</SP> to stage 2<SP>2</SP> of counter Z increments counter HZ 1 and if the latter reaches a count of 5 it actuates AND gate U1 with results as before. The counter DZ finally holds the BCD equivalent of the pure binary input E.

Title: Improvements relating to photo-electric measuring apparatus
IPC: G01N21/51
Filed: 1950-08-21
Abstract: 688,653. Photo-electric particle counting apparatus. LOESCHCKE, H.H., and WEVER, R. Aug. 21, 1950 [Aug. 22, 1949], No. 20685/50. Class 40 (iii). Measuring apparatus for estimating the number of discrete particles contained in suspensions or emulsions in a transparent or translucent medium, comprises means for passing a beam of light through the medium so as to produce a divergent beam of diffracted or scattered rays in addition to the main beam, and a light-sensitive cell arranged to respond to an annular portion of the diffracted beam surrounding the main beam but shielded or otherwise rendered irresponsive to the main beam and the central portion of the diffracted beam. Although generally applicable the invention is primarily concerned with estimating the number of corpuscles in .blood and is adjustable to give satisfactory results with such particles even when these vary in size considerably. The apparatus may consist of a light-tight box 21 in which is placed a lamp 1 the light from which after passing through colour filter 3 is focused on a small hole in screen 5 by lens 4. Light from the hole is made parallel by lens 6 and passes through small holes in two further screens 7 and 8 before impinging on a transparent vessel 9 containing the suspension or emulsion under investigation. The particles scatter or diffract part of the light to form a cone-like beam and, while the main beam is stopped by the central disc 11b of a screen having an annular hole cut in it some of the diffracted light passes through the annular hole and impinges on photo-cell 12. On the further side of lamp 1 there is a further colour filter 17, a ground glass plate 18 and an adjustable diaphragm 19 and a compensating light-sensitive cell 20. In use the photo-cells are arranged with their outputs in opposition and the diaphragm 19 adjusted until there is zero electrical output as shown by a measuring instrument such as a galvanometer, the adjusting arm of the diaphragm co-operating with a scale calibrated to show the number of particles per unit volume directly. It is shown with reference to a graph, Fig. 2 (not shown), that if the semiapex angle of the cone based on the inner edge of the annular opening in the screen 116 and having its apex at the cell 9 is 4 degrees and the semi-apex angle of a similar cone based on the outer edge of the annular opening is 30 degrees then, using yellow light, particles ranging in size between 5Á and 9Á can be counted. Other ranges of sizes will require different angles which may be similarly determined. If the photo-cell 12 is made removable the diffraction pattern can be inspected on a ground glass screen 14, normally covered with a light-tight cover 15. By further slight alterations the apparatus may also be used for absorption tests.

Title: Improvements in television synchronisation
IPC: H04N5/06
Filed: 1936-07-28
Abstract: 471,286. Television. RADIOAKT.- GES. D. S. LOEWE. July 28, 1936, No. 20886. Convention date, July 30, 1935. [Class 40 (iii)] Two sets of synchronizing signals are generated by using the signals of higher frequency as a carrier, for the signals of lower frequency, which are obtained by rectifying the carrier wave. The signals are generated by a light siren 1, and are amplified by a selective amplifier 13 with sufficient high-quality resonant circuits to overcome any irregularities in the generator. The output is connected to a rectifier 16 followed by an amplifier 20 from which the signals of lower frequency are obtained. A ring of slots 2 in the rotating disc 1 are illuminated through a circular diaphragm 9 such that the diameter of the projected circle 3 is equal to the spacing between adjacent slots. Alternatively, the projected light is bounded on one or both sides by a cosine curve 3a of wavelength equal to the spacing between slots, or the light is in the form of a line 4 adjusted to the angle alpha with the radius of the disc which produces optimum results. The carrier is interrupted once every revolution or every second, third, &c. revolution, of the disc by a shutter 15 driven by a synchronous motor 14. Alternatively, some 2a of the slots are wholly or partially covered, or are wholly or partially replaced by a window 15a to produce the modulation of the carrier.

Title: Improvements in unloading valve
IPC: F15B1/027
Filed: 1944-10-27
Abstract: 587,796. Fluid-pressure servomotorcontrol systems. MERIT ENGINEERING, Inc. Oct. 27, 1944, No. 21000. Convention date, June 27. [Class 135] An unloading valve for a fluid-pressure system comprises a body 10, having bores 11, 25 connected at their ends, a main valve 40 in one bore normally subjected to high pressure at its opposite ends and a removable unit 26 in the other bore for controlling opening and closing of the main valve. High-pressure fluidenters through a port 20 and passes to the system by way of a check valve 100 and a port 18; the pressure of.this fluid being transmitted along a passage 27 to a chamber 62, past a pilot valve 78, which is normally held off its seat 76 by a spring 86, through passages 71, 72 to a chamber 74, and thence to a chamber 54, whore the pressure acts on the lower surface of the main valve, the area of which is greater than that presented to. high-pressure fluid at the main valve seat 36, so that the valve temains closed. When the pressure in the system rises to a predetermined value, the fluid pressure'on the pilot valve 78 overcomes the opposed pressure on a ball 85 and the pressure, due to the spring 86, and the pilot valve is closed, thus cutting off communication of the high-pressure fluid with the chamber 54. At the same time the ball 85 is raised from its seat to release the pressure in the chamber 54, through passages 66, 67 and a relief port 23. The main valve is then opened by fluid pressure acting on its end adjacent the seat 36, to permit fluid to flow from the inlet 20 direct to the relief port 23. When the pressure in the system has fallen to a lower limit, the spring 86 will reopen the pilot valve to allow fluid to enter the chamber 54 and again close the main valve.
