Abstract
429,690. Television. MARCONI'SWIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, and WALKER, L. E. Q., 98, Wymering Mansions, Maida Vale, all in London. Dec. 5, 1933, No. 34206. [Class 40 (iii)] In a scanning system using a ring or partial ring 4 of fixed mirrors, two reflectors 3, 5 rotate together, and a stationary reflecting surface 2, associated with one reflector 3 always presents the same angle to incident light, and a reflecting-surface 6 associated with the other reflector 5 always presents the same angle to emergent light. The reflector 3 reflects incident light to the mirror ring from which it is reflected to the reflector 5 from which it is reflected to a screen or other area to be scanned. The rotating reflectors are right prisms with their hypotenuse faces at 45‹ to the axis 7 of rotation.
