Abstract

212,249. Freund, E., and Brociner, S. Dec. 19, 1921, [Convention date]. Addition to 190,490. Metering systems. - When a connection has been established, a preliminary talking circuit is completed for a few seconds only during which the calling subscriber may ascertain the correctness of the connection. If during this interval the calling subscriber operates his meter or starts his time-recording device, the cutting-off threat is removed and a permanent talking connection established. The Figure shows the invention applied to a semi-automatic connection between two subscribers A, B. When the called subscriber B replies, the feed-relays f, g complete a circuit S, 1, 2, 3, 4 for a relay Z controlling a timing-apparatus, which threatens to cut off the connection at the end of 10 seconds. The depression of metering key ZT during this interval short-circuits relay f thus opening the circuit of the timing-relay Z. The Specification as open to inspection under Sect. 91 (3) (a) states that in a time-controlled system, conversations can be extended beyond the regular time by operating the metering-key again before the previous stage is exhausted, and comprises also the application of the invention to a manual exchange, and a semi-automatic system which is identical with a system described in the parent case as open to inspection under Sect. 91 (3) (a). This subject-matter does not appear in the Specification as accepted.
