Abstract

502,696. Television. TRAUB, E. Oct. 5, 1937, No. 26937. [Class 40 (iii)] A stationary mirror ring scanning device consists of prismatic blocks 3 of trapezoidal crosssection with mirrors formed on or carried by the narrow end faces, the blocks being laid side by side within a shell 4 and held in position by pressure applied by the screw 5 against the free faces of the two end blocks. The reflecting surfaces of the blocks may be inclined differently or made concave, the several blocks then being displaced relative to one another in a direction parallel to the axis of the device. This latter arrangement is particularly suitable for use in secret television systems, since the blocks may be displaced axially, e.g. by inserting distance pieces between the underside of the blocks and the flange 4, to alter the scanning order. Specifications 419,120, 425,552, 440,055, 448,238, and 465,970 are referred to.
