Abstract: 366,575. Synchronous movements. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Knoop, W. A. ; 36, St. Paul Road South, Hempstead, New York, U.S.A.) Nov. 6, 1930, No. 33437. Convention date, Dec. 4, 1929. [Class 40 (iii).] In a phase-correcting system for synchronized rotary distributers CD, SD, RD, the central portion of an impulse is suppressed and rapidly changing portions preceding and succeeding the central portion are impressed differentially on a correcting apparatus to produce a proportional correcting effect. Voltage impulses due to signals in a line 10 are produced in the secondary winding of a transformer 12, but only those which tend to make the distributer ring 13 negative are effective owing to a rectifier 19. The segmented ring 14 of the distributer CD comprises alternate live and dead segments. At synchronism an equal part of the rise and fall of each impulse is applied by the rotating brush 15 to successive live segments and hence to the grids of valves 16, 17, which are shunted by condensers 30, 31 to prolong the impulses. On departure from synchronism, unequal currents flow from the plates of the valves through the two windings of a relay 20 and operate its armature 21 to contact 22 or 23 to cause current of such polarity to energize a motor M that the phase displacement of the distributer is corrected bv a differential gear 26. A differential ammeter 32 provides a visual indication of want of synchronism. According to a modification the mechanical relay is eliminated, Fig. 2 (not shown). Specification 317,528, [Class 40 (iii), Telegraphs, Electric], is referred to.

Abstract: 1,246,794. Selective signalling. G. D. PETERS & CO. Ltd. 18 Oct., 1968 [21 July, 1967], No. 33719/67. Heading G4H. Articles on a conveyer are sorted in accordance with their weight or price by digitizing a signal derived from a weighing station and stepping each digitized signal along a series of registers, associated with sorting gates, in synchronism with the movement of the articles along the conveyer, coincidence circuits controlling the operation of the sorting gates in accordance with the result of a comparison of the digitized signal in the corresponding register with a preset value. The output 2 of a strain gauge representing the weight of an article is applied to a circuit 1 where it is integrated over a fixed time interval following that in which the first overshoot occurs. A potentiometer 7 is preset to the price per unit weight and gives an output 8 representative of the price of the article. The digitizing circuit comprises a comparator 9, clock generator 14, counter 15 and a feedback D/A converter 17. When gate 16 closes at the end of a digitizing operation or detection of an overweight article by gate 21, a shift pulse is generated at 23 to transfer the counter 15 contents to a first buffer stage 24. A magnetic proximity switch detects an article as it leaves the weighing station and causes shifting of the digitized signals along successive buffer stages 24 and successive sorting gate registers.

Title: Improvements in devices for automatically retransmitting coded information
IPC: H04L25/04
Filed: 1965-08-06
Abstract: 1,105,534. Telegraphy. COMPAGNIE FRANCAISE THOMSON HOUSTONHOTCHKISS BRANDT. 6 Aug., 1965 [19 Aug., 1964], No. 33879/65. Heading H4P. In a station at which received telegraph characters are recorded in punched tape which is subsequently read for retransmission, additional signals are automatically punched after the end of the message to ensure the reading of the last few characters of a received message which otherwise would remain in the section of tape between the punch and reader. Since all 32 code combinations are employed in normal transmission the additional signals are distinguished from the message by preceding each message character on the punched tape by one selected character and the service signals by a different selected character. The punch and reader therefore operate at twice the character rate. The additional signals are not punched unless there is more than a preset interval between successive messages. The reader circuitry includes means to prevent the selected characters and the additional characters from being transmitted.
