Abstract
754,630. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 19, 1954 [Oct. 20. 1953; Feb. 9, 1954], No. 30051/54. Drawings to Specification. Class 40 (3). A " compatible " colour television receiver employs at least two picture reproducing tubes, the screen of one of which is provided with a white luminescing phosphor and in front of which is arranged a removable colour filter which passes the primary colour not supplied by the other tube(s), means being provided for removing this filter from the optical path and for rendering inoperative the other tube(s) for the reception of black and white television signals. If the removal of the filter disturbs the optical path it may be restored to a desired direction by the insertion of further (non-colour selective) optical devices. For colour reproduction the partial images may be combined by colour or non-colour selective means and the function of the colour filter in front of the white phosphor tube may be performed by such means when colour selective.
