Abstract: 1,218,193. Transfer mechanism. LITTON BUSINESS SYSTEMS Inc. 10 April, 1968 [25 April, 1967], No. 17400/68. Heading G4D. In a calculating machine racks 1 are moved differentially to the right, after which a carriage 9 is raised to shift the register bodily and bring add wheels 5 or subtract wheels 6, as the case may be, into mesh with the racks 1 which are then returned to home position to enter the appropriate digits. If a wheel 5 or 6 passes through zero then a tooth extension 5a or 6a deflects the nose 16a of a lever 16 for that denomination, so that a catch 20 is freed and a gear segment 22 associated with the next higher denomination rocks clockwise under spring action. The carriage 9 is lowered to bring the other wheels 6 or 5 into mesh with the gear segments 22. Those which have been displaced are then returned by a bail 14 to effect transfer. If at this time the tooth 6a or 5a is in position " 9 " then, under downward movements of the carriage 9, it depresses a spring-pressed slide 22, the other end of which engages a slot 28 in the next higher gear segment 22. Therefore transfer is effected in the higher denomination also. A bail provides for fugitive one transfer.

Abstract: 906,468. Radio direction finding. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Feb. 21, 1961 [May 18, 1960], No. 17545/60. Class 40 (7). In an automatic radio direction finder giving improved discrimination against adjacent channel interference by the provision of a narrow effective bandwidth, signals received by a non- directional aerial OA and by a directional (e.g. Adcock) aerial AA are reduced to a common low frequency (e.g. 2 kc/s.) by means of frequencychangers 1, 2 and 5, 6 with respective oscillators 3, 4 and supplied to band-pass filters 7, 8 having a pass-band of 2 kc/s. Œ 100 cps. The output from filter 8 is supplied to a switch device 9 which operates to periodically reverse the phase of the input signals at twice the frequency (400 cps.) of a switching control source 10 and supplies output signals to a combining circuit 11 to which is also supplied the output signals from filter 7 in a phase-control circuit 15. In circuit 11 the two input signals are combined such that they add when one relative phase is present and are subtracted when the other relative phase occurs and the output thus consists of the received (frequency-changed) signals modulated at the switching frequency (400 cps.). This output signal is rectified by rectifier 12 and the modulation frequency selected by a filter 13 is supplied as one input to a two-phase motor 14 in phase quadrative with the second input derived from switching control source 10. The motor 14, which is mechanically coupled to the search coil SA of the Adcock aerial, then operates automatically to rotate the search coil in either direction until the output signal from filter 13 falls to zero, this position then indicating the bearing of the received signals. Audio monitoring is provided by a detector 16, audio amplifier 17 and a loud-speaker 18.
