Title: Colour television systems
IPC: H04N9/24
Filed: 1971-11-26
Abstract: 1370426 Colour television N FARMER and B WINNING (trading as FARMERS) 26 Nov 1971 [28 Aug 1970 10 March 1971] 57415/73 and 57416/73 Divided out of 1370425 Heading H4F In a colour television receiver using a tube provided with two sets of parallel index electrodes which are connected to a resonant circuit, a chrominance signal containing information as to hue and saturation is controlled in phase by the index signal derived from the tube. The index signal may be at 88 KHz which is multiplied by 5 to derive a signal at 4À43 MHz corresponding to the colour sub-carrier of the PAL system. In one arrangement, Fig. 10 (not shown), two index signals at 4À43 MHz separated in phase by 120 degrees are respectively used to modulate (R-Y) and (B-Y) input signals, the outputs of the modulators being added and fed to the tube as a chrominance drive signal. In a modification (Fig. 11, not shown), the index signal at 4À43 MHz and two orthogonal signals from a reference oscillator at the same frequency are fed to a synchronous detector to derive two signals R1 and R2 which modulate the input signals. The relative amplitudes of R1 and R2 are related to the detection axes and may be used uncorrected if the widths of the phosphor stripes in the tube are unequal for the three colours; alternatively R1 and R2 may be corrected to give symmetrical hues in the output. In another arrangement, Fig. 12, the signals R1 and R2 are equal amplitude quadrature components derived by a frequency doubler 126 from a reference oscillator 125. Since the addition of these signals in unmodulated form results in a signal of 45 degrees phase, a corresponding phase shift is inserted at 127 in the chrominance sub-carrier, before it passes to the synchronous detector 128 which is supplied with reference signals derived from the index circuit 104 via frequency multiplier 107. The units 105 and 106 correct the phase of the index signal in accordance with any non-linearity in the beam scanning velocity. The signal A derived by adding the outputs of modulators 120 and 121 has a phase to hue relationship similar to the transmitted signal but suitable adjustment may be made to R1 and R2 to give symmetrical hues. When the chrominance signal is used to vary the scanning speed of the beam the saturation level is obtained by comparing the levels of the complementary hue in the luminance signal and in the sub-carrier. For this purpose (Fig. 13, not shown) the sub-carrier is synchronously detected and fed to a matrix to produce the matrixed level of the complementary hue, that is the sum-[(R-Y)-(B-Y)-(G-Y)] which is fed through a saturation correction circuit to the adder 108; a correction is also fed to the luminance drive 111.

Abstract: 1,223,568. Fluid pressure actuators. GIRLING Ltd. Nov.26, 1968 [Dec.22, 1967], No.58495/67. Heading F1P. [Also in Division F2] In a fluid pressure actuated motor, particularly for a dual braking system (Division F2), at least two pistons 18, 20 are coupled together in tandem and work in separate cylinder spaces formed in outer cylindrical wall portions, 10, 64, the outer cylindrical wall portion 64 being encircled over a part of its axial length by the outer cylindrical wall portion 10 and the cylinder spaces are separated by a fixed wall 12. The pistons 18, 20 are connected by a stem portion 29 forming part of a pressure member 30 which passes through the fixed dividing wall 12 between the chambers 22 and 24 which are open to atmosphere and the stem abuts against a thrust pad 34 welded to the back face of the piston 18. A force transmitting element 44 extends from the piston 18 and has connected thereto a force transmitting push rod 42 which extends through a central aperture 40 in an end wall 14 of the motor casing. In operation, when compressed air is fed into the chambers 26 and 28 a pressure differential is created across the pistons 18 and 20 which move in opposition to a return spring 52 to displace the push rod 42 outwardly to actuate the vehicle brakes. When used in conjunction with a dual braking system the inlets 56 and 58 are each connected to separate pressure sources such that failure of one source of supply will not cause a complete failure. Should the supply to the rear cylinder fail, the forward piston 18 can move forwardly on its own leaving the rear piston behind and if the supply to the forward cylinder fails the rear piston can move forwardly pushing the forward piston ahead of it. Instead of being operated by compressed air the motor can be modified so as to be vacuum operated or hydraulically operated.

Patent GB-682460-A (GB)
Abstract: 682,460. Ignition systems. GENERAL MOTORS CORPORATION, Feb. 15, 1950 [Feb. 16, 1949], No. 3824/50. Class 7 (iv). In an ignition system comprising a main condenser 44 connected to the primary 45 of an ignition coil 46, to the secondary 47 of which the spark plug 48 is connected, means, such as a voltage doubler having series connected condensers 36, 37, fed from a cold cathode rectifier 31, for charging the main condenser, a thyratron 43 controlling the discharge thereof, an auxiliary condenser 59 connected to the charging means, and through contact breaker contacts 55, 56 to the grid 43a of the thyratron 43, there is provided a spark prolonging condenser 61, also connected to the . charging means and to the spark plug 48 through the secondary 47 of the ignition coil 46, which discharges to maintain the arc for a longer period! than would otherwise result from the discharge of the main condenser 44 alone through the ignition coil primary 45. The ignition system is energized from either a battery 10 or a generator G connected through an ignition switch 17 and a suppressor with the centre taps of a two-part primary winding of a transformer 11, which primary is associated with a vibrator 21 having two separate sets of contacts 26, 28 and 27, 29 each set being in circuit with one part only of the primary winding in order to reduce the current carried by the contacts. The transformer secondary winding 16, which is shunted by a condenser 34 that absorbs any transients caused by the vibrator operation, is connected, through the voltage doubler to a terminal 39 maintained at a potential of between 800-1,500 volts depending upon the state of charge of the battery. Terminal 39 is connected to the spark prolonging condenser 61, the anode of the thyratron 43, a resistance 42 and the main condenser 44; the other end of resistance 42 is joined to a wire 50 between which and another wire 53 is a voltage regulator 52 that limits the voltage across these wires to, say, 750 volts, and the auxiliary condenser 59, one plate of which is earthed and connected to the cathode of the cold cathode thyratron 43. The voltage regulator 52 ensures adequate charging of condenser 59 irrespective of the potential of terminal 39 since it will not pass current if the applied voltage is less than 750 volts, whilst any voltage in excess of 750 is absorbed in resistance 42. When the engine operated contacts 55, 56 are closed condenser 59 discharges to grid 43a and thyratron 43 becomes conductive so that main condenser 44 discharges through primary 45 and causes break-down of the sparking plug 48 whereby the circuit for discharge of condenser 61 is completed, which discharge prolongs the spark across the plug gap. The rate of discharge of condenser 44 is greater than its rate of charge from terminal 39 so that upon cessation of its discharge the thyratron will again become non-conductive. The invention is particularly useful to enable sufficient heat to be given to the combustible mixture when using plugs with short spark gaps. Specification 626,190 is referred to.
