Abstract

520,235. Variable resistances. KOLSTERBR,ANDES, Ltd., and SMYTH, C. N. Oct. 11, 1938, No. 29464. [Class 37] [Also in Group XL] In a television receiver, the currents in the deflecting coils H.V., and hence the vertical and horizontal deflections produced are dependent on the position of a contact C on the face of a plate B of resistive material. The plate carries transverse current from separate sources 6 and acts as a balancing potentialdivider in two bridge circuits, in which the coils are so arranged respectively that they carry no current when the bridges are balanced. Reference has been directed by the Comptroller to Specification 500,809, [Group XL].
