Abstract: 743,233. Gauges. ACIERIES ET FORGES DE FIRMINY. Aug. 31, 1953 [Sept. 16, 1952], No. 23995/53. Class 106 (2). [Also in Group XXII] In a pass adjusting device for a rolling mill a pair of measuring members is adapted to detect a preset distance between the rolls at each end and controls automatic means for maintaining the distance constant. In an example in which the roll pass is adjusted by hydraulic rams 65, Fig. 6, controlled from a hydraulic accumulator 64, each measuring member comprises a pneumatic nozzle 22 which detects a preset distance between cylindrical extensions 7, 8 of the rolls by pressure changes resulting from a variation in the outlet orifice section. A given value of pressure balances a diaphragm manometer 54 against the pressure behind a preset needle valve orifice 52. An electric contact 55 on the manometer controls a solenoid valve 59 connecting the hydraulic accumulator 64 to a supply 60 or exhaust 66. The mounting for the pneumatic nozzle 22, Fig. 4, comprises a slide 21 adjustable on a frame 15 having projecting feet 17, 19, 20 engaging the cylindrical extensions 7, 8 and held in position by an adjustably loaded spring 33. The slide 21 has feet 30 which are yieldingly held in engagement with V-grooves 28 on the frame 15 by a spring 23. The slide 21 at each end of the rolls is adjustable in position by a worm spindle 24 rotated through bevel gears 25, 26, shaft 46 and one of a pair of hand wheels 36, 42 which permit separate adjustment of the ends until the rolls are parallel and are then locked together for regulating the pass.

Title: Apparatus for measuring the dwell of an automotive ignition system
IPC: F02P17/00
Filed: 1976-06-14
Abstract: 1515456 Measuring dwell-ratio of an ignition system for an IC engine SUN ELECTRIC CORP 14 June 1976 [16 June 1975 31 March 1976] 24563/76 Heading G1U In a system for determining the dwell ratio of an ignition system by examining the voltage across the primary winding of the ignition coil, particularly when because of the use of electronic switching the dwell portion B, Fig. 3, of the primary voltage, of which one full cycle A-B is shown, is not absolutely zero (as it is when conventional mechanical points are used for switching) but is merely near zero for a first part (2) to (3) of the dwell portion and then rises (3) to (4) during the latter part of the dwell portion prior to the initiation (1) of the next spark, a first threshold circuit Ql, Fig. 2, monitors the primary voltage from a terminal D7 via a full-wave rectifier IC1, IC2, and allows a capacitor C1 to charge from zero towards +15v, when it is sufficiently small, and a second threshold circuit IC3 which when in its on state (output voltage +15v) monitors the capacitor Cl voltage and switches to its off state (output voltage -15v) when the capacitor Cl voltage exceeds a threshold of about +5v set by a Zener diode D9, and which in its off state monitors the primary voltage directly, via a diode D5, and switches to its on state when the primary voltage becomes sufficiently large as when the next spark (1) is initiated. Thus the off/on ratio of the threshold circuit IC3 corresponds to the dwell ratio B/A, but differs therefrom in that the on time is too long by an amount t, this being the time taken for the capacitor C1 voltage to rise above the turnoff level of threshold IC3. A further pulse train is therefore derived from the output of threshold circuit IC3 in which the on-time is reduced by an amount t. This is achieved by a Schmitt trigger IC4 and a capacitor C2. The resulting waveform which has the required off/on ratio is clipped  above and below, IC5, IC6 and smoothed IC7, to provide a d.c. representing the dwell ratio.

Abstract: 773,221. Pulse generator circuits. METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Sept. 12, 1955 [Aug. 25, 1954], No. 24726/54: Class 40(6) A pulse generating circuit comprises a pair of pulse forming networks which are charged in parallel from a voltage source together with switching means for reversing the connections of one of said networks relative to the other whereby upon each reversal both networks discharge in series through a load circuit to generate unidirectional pulses. The Figure shows a pulse generating circuit in which two pulse forming networks DL1, DL2 are arranged to charge in parallel from the supply voltage source through inductor H and rectifier D when switches S1 and S4 are closed, S2 and S3 remaining open. If now the switches are changed over, i.e. S1 and S4 are opened and S2 and S3 closed, the connection of DL1 relative to DL2 will be reversed and the two networks will discharge in series through the load RL to generate a pulse. At the end of the pulse DL1 and DL2 will charge up again in parallel from the supply voltage through switches S2 and S3. If now the switches are again changed over DL1 will again be reversed with respect to DL2 and the two networks will discharge in series through the load RL. In this way a series of unidirectional pulses of amplitude equal to twice the supply voltage will be produced across load RL. The switches S1 to S4 may be mechanical switches or gas filled discharge tubes such as thyratrons or ignitrons. In a modification Fig. 2, not shown, the load resistor is placed in series with the bridge formed by the switches Sl to S4.

Title: A method of synthesising a digital waveform
Inventor: RALPH FRANK
IPC: H03C1/60
Filed: 1966-06-03
Abstract: 1,107,346. Amplitude modulation; pulse Circuits. STANDARD TELEPHONES & CABLES Ltd. 3 June, 1966, No. 24785/66. Headings H3P and H3R. A digital waveform, which has only the fundamental and prescribed harmonics present, e.g. for use in a polyphase modulator in a frequency translation system as described in Specification 1,081,240, is synthesized by providing a repetitive signal of fundamental period T and adding to this signal an identical signal delayed by a time T/2x, where x is an integer, to produce a waveform having the xth harmonic component missing. Further harmonics may be removed by successively repeating the adding operation in each case using the resulting waveform from the preceding adding operation as the basic waveform. The adding operation removes not only the xth harmonic but also the 3xth, 5xth, 7xth &c. harmonics. The waveforms may be produced by apparatus as shown in Fig. 6 in which a basic waveform, produced in unit 16, is applied direct and via a delay 5 to an adder unit 6, the output from which is applied direct and via a delay 7 to an adder 9 so that the resulting waveform has two selected sets of harmonics removed, dependent on the value of the delays in 5 and 7. The output is applied to a unit 8 which provides outputs having phases differing by 120 degrees which are said to be of use in multipath time domain techniques. Fig. 11 shows a block diagram of the N path configuration of a frequency translation system, each path of which includes modulators 1 and 3 and filter 2, which selects a band of frequencies from an input spectrum and translates it, either erect or inverted, to an output spectrum. The signals f1 and f2 of each channel differ in phase from the respective signals of the adjacent channels by T/N, where T is the period of the signal, N is the number of channels, frequency f1 is the midband frequency of the input signal and f2 the midband frequency of the output signal. By using signals for the frequencies f1 and f2 which are of the type produced by apparatus of the invention, the filtering of the input and output signals is simplified. In addition, a comb filter of the type shown in Fig. 12 and in which the switches S1 to SN are operated to connect the capacitors C across the line sequentially, one at a time, may have the switches S1 to SN operated by switching signals of the type produced by this invention, in the multi-phase form, i.e. N phase signals, in order to eliminate some of the pass bands.

Title: Improvements in or relating to automatic frequency adjustment in receiving installations

Abstract: 689,264. Radio receiving systems. SIEMENS- & HALSKE AKT.-GES. Oct. 11, 1950 [May 18, 1949], No. 24870/50. Class 40 (v). [Also in Group XXXV] Circuits for automatic frequency adjustment of diversity radio receiving stations comprise one or more local oscillators feeding in common the early frequency-reducing stages of all the stations, whilst a later frequency-changing or mixing stage is fed by local oscillations individual to each station. Regulating voltages derived from the latter oscillators are connected in parallel or in series and are used to control the frequency of one of the earlier oscillators. The Figure shows a diversity arrangement for the reception of frequency shift telegraph signals. The radio signals are received on spaced aerials I, II and are reduced in frequency by successive mixing stages M1, M2, M1<SP>1</SP>, M2<SP>1</SP>, the oscillations for mixers M1, M1<SP>1</SP> being supplied by a common source G1, and those for mixers M2, M2' by a common source G2. The outputs X, Y from the mixers M2, M2<SP>1</SP> are fed through filters to further mixers M3, M3<SP>1</SP> in which their frequencies are reduced to a pair of audio tones representing marks and spaces. The heterodyne sources G3, G3<SP>1</SP> for the mixers M3, M3<SP>1</SP> are separate. In order to synchronize the source G3 so that it may provide the desired output tones at M3, a further source G4 operating at the frequency of one of the tones, e.g. the marking tone, is mixed at M4 with the output from the mixer M2 with the result that each mark signal gives a difference frequency which is selected by a filter StF, amplitude-limited at B, and used to lock-in the source G3. At the other receiver, the source G4<SP>1</SP> operates at the desired spacing- tone, and a similar lock-in of the source G3<SP>1</SP> is effected. The control input and the output of the sources G3, G3<SP>1</SP> are compared in phase by the respective mixers Ph, Ph<SP>1</SP>, the D.C. outputs of which are used jointly to adjust the frequency of the source G1 supplying the mixing stages M<SP>1</SP>, M1<SP>1</SP>. The output of each source G3, G3<SP>1</SP> is also fed through attenuators b<SP>1</SP>, b to the input of the other source, the reciprocal connection providing continuity of control of both sources. In an alternative arrangement, one at least of the receiving stations makes use of both the marking and spacing frequency to form the regulating voltage for the source G3 or G3<SP>1</SP>. The frequency control system may be used in diversity reception of single sideband telephony. Specification 685,798 is referred to.
