Abstract

749,061. Order telegraphs. SIEMENS & HALSKE AKT.-GES.. Feb. 20, 1953 [Feb. 23, 1952; April 7, 1952], No. 4847/53. Class 40(1) The order telegraph system shown in Fig. 1, in which the order and its acknowledgement are effected by rotating field systems 3, 2 and relays or relay windings A, B, C are connected between corresponding wires to give warning if an order is not correctly acknowledged, is modified by the use of a single relay with three windings 4, 5, 6, Fig. 2, two of which are polarized by rectifier bridges. Specification 669,116 is referred to.
