Abstract

280,630. Hall, R. Aug. 17, 1926. Television apparatus. -An exploring device for a television system comprises two coaxial slotted discs rotated at different speeds and characterized by (1) straight slots in one disc and curved slots in the other disc all extending inwards from the peripheries of the discs or (2) straight slots at different angles in the two discs extending inwards from the peripheries, or (3) the slots in the two discs being such that when their inner ends are superposed, the outer ends meet at or near the peripheries without the slots crossing each other. Fig. 1 shows an arrangement corresponding to conditions (1) and (3). The rapidly rotated disc is provided with curved slots B and the other disc, rotated slowly in the same or the opposite direction, is provided with straight radial slots A. Fig. 3 shows similarly an arrangement cor. responding to conditions (2) and (3). The lightsensitive device at the transmitting station may be in the form of strips of light-sensitive material covering the slots A in the slowly-rotated disc. The strips covering the different slots are interconnected at their inner ends X<1>, and each is provided at its outer end X with a contact cooperating with a segmental collecting contact. If the image to be transmitted covers more than one sector between the straight slots, a corresponding number of collecting contacts, each in a separate transmitting channel, is provided. The discs may be formed of thin opaque material fixed to thin sheet celluloid or other transparent material. Transmission may be effected by the use of infra-red and ultra-violet rays instead of light. An intermediate record of the image may be obtained by converting the fluctuating current into sound impulses and recording these phonographically. A purely local reproduction of the image may be obtained by using different areas of the same pair of discs for the transmitting and re - constituting explorations. Specifications 5339/98 and 218,766 are referred to.
