Abstract
634,093. Electric follow-up systems. CHADBURNS (LIVERPOOL), Ltd., and BREWERTON, N. E. Sept. 13, 1946, No. 27510. [Class 40 (i)] In a telegraph system, e.g. for a ship's engineroom, the transmitting handle 14 moves one part of a follow-up switch, comprising contacts 15, 16 so that one or other makes contact with the fixed contact 12, according as the handle is moved " ahead " or " astern," to operate one or other of two self-interrupting relays 27, 28 which impulse simultaneously the corresponding ratchet magnets 17 or 18 to rotate the other part of the follow-up switch and the ratchet switch 23, 24 at the receiver to operate the receiver indicator 22. In a modification, to ensure that the relays 27, 28 remain on or off long enough to allow the ratchets to operate, a condenser may be associated with 27, 28 or the latter may have a mechanical time lag device in the interrupter mechanism. In a further modification the contacts 15, 16 are caused to operate by a differential between the transmitting handle and the disc 20.
