Title: Improvements in or relating to sawtooth generators and to polar position-indicators embodying sawtooth generators
IPC: G01S7/12
Filed: 1949-04-01
Abstract: 706,313. Saw tooth generating circuits; pulse radar. PHILIPS ELECTRICAL, Ltd. April 1, 1949 [April 6, 1948], No. 8914/49. Classes 40 (6) and 40 (7) In a sawtooth generator of the Miller type in which a capacitor 4 connected between the anode and grid of a valve is periodically charged and discharged, a grid leak 5, the charging voltage 6' and a source of negative grid bias 8', 8" are connected in series-between the grid and cathode and the charging voltage is periodically rendered operative by opening a switch bridging the series combination of charging voltage source and grid leak. The bias may be adjusted such that the valve is normally conducting so that the anode voltage step which usually occurs at the start of the long flank of the output wave is avoided and so that both positive and negative going output waves may be produced. The charging voltage may be sinusoidal so that the amplitudes of successive sawtooth waves follow a sine curve, Fig. 6, two of such generators with the sine waves in quadrature being suitable for producing the deflection voltages in a plan position indicator. The switch comprises reversely arranged diodes periodically rendered conducting by pulses applied to their series resistors 16, 17. A resistor 20 causes a sharp change in anode voltage to occur at the commencement of the long flank of the output wave and may be adjusted so that the anode voltage at start of the long flank is equal to the average value of the wave and the output from the coupling capacitor 13 at this point in the wave is zero. The adjustment is independent of output voltage amplitude.

Title: Improvements in frequency monitoring systems
IPC: G01R23/00
Filed: 1942-07-07
Abstract: 556,057. Measuring frequency. BRITISH THOMSON-HOUSTON CO., Ltd. (General Electric Co.). July 7, 1942, No. 9395. [Class 37] In a frequency-monitoring system such as for frequency-modulation broadcast systems, a pair of normally-balanced sets of oscillations of the desired frequency are set up, rectified, and applied differentially to an indicator whereby changes in polarity and intensity are indicated. Oscillations, say, of frequency F, set up in coil 2 from a transmitter 1 are mixed at 6 with oscillations say of one-tenth that frequency set up in a crystal-controlled amplifier 4 as shown at M and fed through a harmonic amplifier 5 to produce oscillations of frequency 9M, the resulting beat frequency M being detected at 7 and fed to a transformer 8 having a tuned primary 9 and tuned secondary 11. The H.T. side of 9 is connected to the mid point of 11 so that the output, comprises the primary voltage together with in quadrature therewith, the respective secondary voltages, and is fed through oppositely poled diode rectifiers 14, 15 and resistances 20, 21, to the mid point of which a centre-reading instrument 22 is connected. The instrument-reading is zero for normal frequency, but changes from normal are shown by the direction and amount of deflection from zero. In order to provide a true reading, the intensity of the oscillations fed to the transformer is initially adjusted, by means not shown, to the proper level indicated by a voltmeter 25. The return circuit from instrument 22 to the mid point of 11 includes a pair of resistances 23, 29 with common point earthed at 18, whereby, with the aid of an indicator 31 and switch 30, the magnitudes of the opposed modulation-scales of the transmitter can be measured. The monitor may be calibrated by throwing switch 33 to the upper position. An equipment is also described wherebv the monitor is tuned to one frequency whereas it can be adapted to monitor transmitter of different frequencies Fig. 2 (not shown).

Title: Improvements in and relating to electric regulators
IPC: H02P7/26
Filed: 1946-03-27
Abstract: 700,340. Automatic voltage control systems. BRITISH THOMSON-HOUSTON CO., Ltd. March 27, 1946 [March 31, 1945], No. 9428/46. Class 38 (4) In a regulator for use with a load circuit including, in parallel, a resistive path and an impedance path having a negative impedancevoltage characteristic, a substantially constant voltage is connected in series with a second voltage across the output terminals and the latter is varied inversely with variations, of the current in the impedance path, from a predetermined value. The grid of tube 33 is connected to a point on the potential divider comprising resistances 26, 27, 22, 23, 132, 133, 134 while its cathode is maintained at constant potential by a voltage source connected across leads 24, 25. After initial setting any change in the potential of this grid relative to the cathode, caused by a corresponding variation of voltage across the resistive load 1, changes the anode potential of valve 33, which change is amplified in valve 34 and applied to the grid of valve 17 so that its impedance changes to restore the voltage across load 1 to its correct value. The present invention provides a further regulator 50 for varying the load voltage in accordance with the current conditions in that part of the load which is represented by the non- linear impedances 48, 49. The current supply from transformer 52 and rectifier 53 is stabilized by gas discharge tubes 59, 60 and appropriate voltages are taken from potential dividers connected across leads 54, 55, and a stabilized reference voltage is produced across resistor 65. Current from the load impedances 48, 49 is passed through resistors 111, 112 and 113, 114 but does not influence the steady current through 65 as it is counterbalanced by the shunt circuit through tube 60 and valve 66, whose impedance is changed to accommodate it by having the potential of the point 118, relative to 110, applied to its control grid. The potential of each point 48', 49' is communicated through resistors 125, 126 to the 'grids of valves 93, 90 which have a common cathode resistor 104 so that only the valve having the highest grid potential passes current, thereby influencing the current through double diode 83 to vary the grid potential of amplifier 75 and so change the potential of the point 74. This potential consequently changes in dependence on the greater current flowing in the two paths 48, 49 and by correspondingly changing the potential of the junction of resistors 22, 23 it causes adjustment of the load voltage in accordance with the current flow. The regulator 50 is rendered ineffective by setting the switch 129 to " off " so that the conditions in valve 75 remain steady and voltage control is effected only by the regulator 7. Fig. 3 (not shown) shows an extension of the embodiment in Fig. 1 in which the voltage is controlled in accordance with the highest current in four load paths instead of two.
