Title: Improvements in or relating to beam-indexing picture display systems
Inventor: RUDD DENNIS ARTHUR
IPC: H04N9/24
Filed: 1961-02-24
Abstract: 933,488. Colour television. MULLARD Ltd. Oct. 30, 1961 [Feb. 24, 1961], No. 6868/61. Drawings to Specification. Class 40 (3). In a colour television display system utilizing a beam-indexing cathode-ray tube arranged for scanning across the pattern of colour stripe triplets in a continuous colour sequence (i.e. R, G, B, R, G, B, &c.), the signal applied to modulate the beam intensity comprises, a brightness component, a sinewave component at the triplet scanning recurrence frequency which is modulated in phase and amplitude in accordance with hue and saturation respectively, and a further sine-wave component which is at twice the triplet scanning recurrence frequency and also carries the same phase and amplitude modulations as the fundamental component but has the phase variations in reverse direction, the ratio of the amplitude of the double frequency component to that of the fundamental component being in the range 0.8-1.0 and having a preferred value of 0.9. The invention is stated to reduce the cross-talk and consequent phase errors which are introduced into the indexing signal produced by the tube. Two ways of performing the invention are described. In the first, Fig. 1 (not shown), an indexing signal at the colour triplet recurrence frequency is first multiplied by three and then mixed with the original fundamental sinewave signal. The difference signal is at the desired doubled frequency and by virtue of the subtractive process has the phase modulation reversed. The signal is then added to the original signal and a brightness signal and applied to the cathode-ray tube. In the second, Fig. 2 (not shown), an indexing signal at the triplet recurrence frequency is added directly to the fundamental signal to obtain the sum signal at the double frequency with the phase modulation in a first direction, and is also doubled in frequency and subtracted from the fundamental signal so as to obtain a fundamental frequency signal but with the phase modulation in the reverse direction. Specification 897,982 is referred to. Reference has been directed by the Comptroller to Specification 828,794.

A piezo-electric quartz crystal vibrator comprises one or more quartz elements bonded to one or more elements of a material having similar mechanical properties to form an assembly which will execute vibrations as a whole at a resonant frequency dependent upon one of the overall dimensions of the assembly. A single NT cut rectangular quartz element 20, Fig. 3a, may be bonded at 22 to plates 21 of e.g. glass or poorquality quartz. The method of bonding may be as described in Specification 661,690. The crystal element 20 is of the same width as the plates 21 and is provided on each face with two separate electrodes 23, 24, Fig. 3b, whereby oppositely directed fields may be applied to each half of the element in order to excite face-flexural vibrations. In a modification a face-shear type of vibrator is made by bonding the loading elements to the sides of a CT, DT, ET or FT cut rectangular quartz element to form a square vibrator. In a further modification (Fig. 1, not shown) the element 20 is replaced by two + 5‹ RX cut quartz plates which are bonded face to face and excited to vibrate in a length-thickness flexure mode. One of the elements 21 may be omitted and the other one correspondingly lengthened. The central portion of the quartz element may be replaced by a third loading element which is bonded at either end to the inner ends of the two portions of the quartz element. The temperature coefficient of expansion of the non-piezo-electric elements may be chosen to be equal and opposite to that of the piezo-electric elements so as to obtain an assembly having a small coefficient over a certain temperature range. The dimensions of the various constructions are given in the Specifications 553,204 and 661,690.
