Abstract
946,673. Automatic exchange systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 14, 1960 [Nov. 25, 1959], No. 40048/59. Heading H4K. In an arrangement in which a number of line groups are served by the same or a larger number of switches, line finders or final selectors, of the kind having two pairs of double-ended wipers co-operating with four arcs P, Q, R, S of 50 outlets, each switch has access to two of the groups, the combination being different for each switch. The two groups may be accessible over different wipers under control of a wiperswitching relay, Fig. 2, or half of each group may be reached over each set of wipers, Fig. 3. The Provisional Specification describes other arrangements employing switches with single sets of wipers.
