Title: Improvements relating to colour television apparatus
Inventor: JAMES IVANHOE JOHN PENFOUND
IPC: H04N9/083
Filed: 1956-11-15
Abstract: 873,550. Colour television. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 15, 1957 [Nov. 15, 1956], No. 34936/56. Class 40(3) Colour television apparatus comprises an image pick-up device and colour filters spaced on a filter support which is movable to interchange the filters co-acting with the pick-up tube in a cylic order, the filters dividing light of at least two component colours into spaced stripes so that said pick-up device produces colour separation signals comprising a video frequency signal and carrier waves, corresponding to said strips, modulated by signals representing colour components of the image, and wherein the video frequency signal constitutes a brightness signal whose composition is predetermined by arranging said filter means so that the video frequency signal includes a signal representing a third colour component and in addition signals respecting the first mentioned coloured component in such different proportions that the video frequency signal has said predetermined cam-position. The Figure illustrates an embodiment utilizing a filter 2 having green, red and blue filter sections 4, 5 and 6 with the red and blue sectors divided by opaque arcuate strips of different spacing whereby transverse scanning of the resulting image strips on the camera target results in the production of carrier waves which may be separated by band pass filters 13 and 14. The normal video signal is separated by a low pass filter 12, and in accordance with the invention is made to represent a desired brightness signal Y by controlling the amounts of red and blue contamination added to the green component provided by filter 4. Assuming equal densities for the green, red and blue filter materials and assuming further that the opaque strips are of equal width to the intervening filter strips, it can be shown that if the total extent of filters 4, 5 and 6 is 360 degrees, then to produce a brightness signal Y=0À59 G+0À30 R+0À11 B, the angular extent of filters 4, 5 and 6 is 95 degrees, 193 degrees and 72 degrees respectively. To adjust the relative amplitude of the component signals R, B and Y to compensate for different transmission times of the component colours through the colour filter, amplifiers 16 and 17 of variable gain are included in two of the channels. As an alternative to selecting the angular extent of filters 4, 5 and 6, the transmittance of the red and blue filters may be controlled by adjusting the ratio of the opaque to transmitting area and/or the density of the transmitting area. The filters 4, 5 and 6 may be divided into a large number of filter sections of smaller angular extent interleaved in the appropriate colour sequence so that when the disc is rotated, the light is commutated at high frequency so as to reduce colour fringing effects as described with reference to Fig. 3 of Specifications 852,505. Specifications 787,331 and 856,002 also are referred to.

Abstract: 321,345. Kenyon, C. H. Dec. 4, 1928. Controlling different functions by same lever; controlling-apparatus, arrangements of hand and foot gear in conjunction with; setting and retaining devices.-The usual pedal controls are arranged to be operated by hand, the clutch and .foot-brake being so inter-connected with one another and with a single band lever as to be adapted to be operated either simultaneously or alternatively at will. The accelerator pedal is connected to one end of a rod the other end of which terminates in a knob adjacent to the top of the steering column. A rocking shaft a is mounted on the frame and has an arm g fixed thereon, the arm having a tubular extension h which forms a hand-lever. The extension is slidable on the arm and is pressed upwardly by a spring k, its movement being limited by a pin m and L-slot n. Projections q, r are provided on the extension h, the projection q having a notch adapted to engage un adjustable stop p on a quadrant o, and the projection r being connected by a link s to a sleeve t splined on the shaft a and carrying a cam u. The clutch pedal x has an arm v fixed thereto, this arm having a roller adapted to engage the cam u. The brake pedal z actuates the usual brake rod y and this is connected to an additional rod 10 having a pin- and-slot connection 12 with an arm 13 fixed on the shaft a. In the position shown the brake is " off " and the clutch is held " out " by means of the engagement of the arm v with the cam u, and the projection q with the stop p. To apply the foot brake by hand the lever h is pulled towards the driver, the shaft a is rotated and the arm 13 pulls the rod 10 and applies the brake. To allow the clutch to be engaged by its spring the extension h is depressed and the projection q thereby released from the stop p, after whichthe extension can be moved away from the driver and the cam u rocked to release the clutch pedal. In order to apply the brake while the clutch is engaged the extension h is depressed and then rotated axially to an extent permitted by the slot n, the arm r being thus rotated to the position shown in broken lines in Fig. 2, so that the sleeve t is moved along the shaft until the cam u is no longer opposite the clutch-pedal arm v; the shaft a can now be rocked by the lever g, h to apply the brake without disengaging the clutch. The pedals may be used in the ordinary way if the extension h is depressed and rotated to slide the sleeve t and cam u into the inactive position. A push-button j for the horn may be mounted on the handle i of the extension h.
