Title: Improvements in and relating to control means for colour television
Inventor: WOOD CHARLES BARRINGTON BISHOP
IPC: H04N9/73
Filed: 1955-02-02
Abstract: 798,301. Television. BRITISH BROADCASTING CORPORATION. Jan. 23, 1956 [Feb. 2, 1955], No. 3127/55. Class 40 (3). An arrangement for adjusting the colour balance of television signals representative of different colour aspects comprises three potentiometers 10, 11, 12 individually controlling the level of a different one of three aspect signals and the operating spindles of which are so coupled mechanically that movement of a single control member 29 in any direction varies the level of at least two of the aspect signals. As shown, the spindles of the potentiometers are secured to individual ring members 18, 19, 20, each of which is pivoted in an annular base member 16 (which forms a mounting for the potentiometers) at a point diametrically opposite to that at which the associated spindle is secured the rings being of different diameters such that each is rotatable about the axis of the spindle secured thereto, one within another, and the outermost ring 19 within the base member 16. Each ring is provided with two circumferential slots 27, 28 through which the control member 29 passes, movement of which in a direction parallel to any one pair of slots effects rotation of the rings containing the other slots (and hence of the associated potentiometers) to extents dependent on the plane in which the movement is effected whilst movement in directions not parallel to any of the slots effects rotation of all three potentiometers. In order to prevent the overall brightness level represented by the three signals from changing when the control member is moved (to adjust colour balance) the potentiometer 11 is electrically connected in the opposite sense to that of the other two. Alternatively, by arranging the three potentiometers symmetrically around the base member 16 they may all be connected in the same sense. By suitable orientation of the whole assembly and the connections to the potentiometers it may be arranged that movement of the control member 29 in any direction from a given point gives rise to the same colour change as that represented by a similar movement on the standard colour triangle.
