Abstract
949,639. Linkwork. MARCONI CO. Ltd. July 24, 1962 [Oct. 18, 1961], No. 37361/61. Heading F2K. [Also in Division H4] A nodding aerial 1 is oscillated about an axis 2 by mechanism comprising a differential lever 9 having a central pivot-pin 8 which is connected by tie rods 4, 5 to points 6, 7 on the aerial 1, the ends of the lever 9 carrying pivotpins 10, 11 which are oscillated from a common drive source. Pivot-pins 10, 11 are connected by links 12, 13 to eccentric pins 14, 24 on rotary members 15, 16 respectively which are connected by worm and wheel gearing with shafts 19, 20 which are driven through a differential gear-box by an electric motor 23. By means of a handle 22, adjustment may be effected between limits in which the pins 14, 24 are either in the same straight line, causing maximum nodding oscillation of the aerial, or they are diametrically opposed, in which case no nodding oscillation occurs. Rotary members 15, 16 are mounted in a support member 17 which may be raised or lowered to vary the position of the horizontal axis about which the aerial oscillates.
