Abstract
621,493. Automatic control systems. SPERRY GYROSCOPE CO., Inc. Aug. 16, 1943, No. 35275/45. Convention date, April 30, 1942. Divided out of 621,485. Drawings to Specification. [Class 38 (iv)] [Also in Group XL (c)] In a radiolocation system, a scanning antenna system rotates a directive beam in a cone of small angle enclosing a selected target and the reflected energy produces an error voltage which maintains the axis of the cone in line with the target. The invention is described with reference to a system identical with that described in Specification 621,485. Specifications 494,288, Group XXI], 582,279, 582,492 and 621,492, [Group XL (c)], also are referred to.
