Title: Improvements in or relating to electric means for testing or controlling material
Filed: 1931-02-19
Abstract: 373,261. Testing fabrics, paper, &c. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Feb. 19, 1931, No. 5324. Convention date, May 10, 1930. [Classes 42 (ii) and 96.] For testing and controlling the thickness of rubber strips, paper, cellulose, textile fabrics, linoleum, &c. during manufacture, the material is passed between the plates of a teat condenser arranged in a Wheatstone bridge, the indicating voltage of which, after amplification, is applied to a rectifier bridge by means of which an indication is obtained on a direct-current instrument. The rectifier bridge consists of rectifiers D1, D2, Fig. 1, resistances Ra1, Ra2, and a direct-current instrument G. An auxiliary voltage Eh, which is high compared with the amplified indicating voltage Eb of the measuring bridge, is arranged so that the voltages Eh, Eb are added in the circuit of the rectifier D1 and subtracted in the circuit of the rectifier D2. The deflection of the instrument G is proportional to the voltage Eb. The auxiliary voltage Eh may be supplied through a phase-shifting potentiometer from the buzzer that supplies current to the measuring bridge. The rectifiers D1, D2 may be of the cuprous oxide type. The test condenser consists of a fixed plate 1, Fig. 4, supported on four porcelain insulators 2, and an upper earthed plate 3 which can be lifted and lowered by means of a lever 6. For controlling the manufacture of threads, these may be passed to and fro within the condenser between rolls. For use with material with a profiled surface, such as motor tyre strips, the condenser plates may be similarly profiled. The instrument G may be replaced by a relay controlling the roll pressure &c. Specification 363,308, [Group XXXVI], is referred to.

Title: Improvements relating to data transmission systems
Inventor: SIMMONS BRIAN DESMOND
IPC: H04L27/30
Filed: 1964-02-10
Abstract: 1,027,108. Data transmission. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 28, 1965 [Feb. 10, 1964], No. 5445/64. Heading H4P. In a data transmission system in which each character is transmitted as a two (or more) frequency signal having a prefix or a suffix two (or more) frequency signal, the receiver includes means for checking, for each character, that the sequence, the time relationship, and the duration of the signals are correct. The embodiment described comprises both keyboard and tape input. In one mode of operation depression of an end of message (e.o.m.) key causes the transmission of a twofrequency prefix signal and a two-frequency data signal. The two frequencies in each character are chosen from two different groups of four frequencies. The prefix frequencies are the same for each character. The receiver checks the presence and duration of the prefix frequencies and that the data signal follows it within a certain time and lasts for a certain time. When the e.o.m. signal is found to be correct, the receiver returns an answer back signal which, if of correct duration, initiates automatic transmission from a tape reader, the characters being converted to the two frequency form and prefixed as above. The signals are receded at the receiver for recording on tape. To ensure that the messages are of the correct length, the receiver counts each character. A gating arrangement indicates whether or not a message has held the correct number of characters. Several message lengths are catered for. In modifications the prefix is replaced by a suffix, storage being provided at the receiver as a consequence. Upon reception of the answer back signal manual initiation of the tape reader may be made, or the message sent from the keyboard.

Filed: 1971-02-26
Abstract: 1382042 Rectifying WESTINGHOUSE BRAKE & SIGNAL CO Ltd 3 Jan 1972 [26 Feb 1971] 5584/71 Heading H2F In a rectifying system comprising two controllable rectifiers 1, 2, interconnected by an interphase reactor 3, and which controls the current in a load circuit 4, 5 by operation for discrete bursts of supply cycles or by adjustment of the conduction of the angle within the bursts, the firing signal control system determines for each successive burst which of the two controllable rectifiers is the last to conduct and so ensure that over a number of such bursts, a substantially zero aggregated voltage time integral is applied to the interphase reactor 3. As described, the bridges 1, 2 of thyristors are respectively supplied from three-phase A.C. via delta-delta and star-delta transformers so that the output current exhibits twelve ripple peaks per cycle. Each burst is initiated by a pulse from a generator 23 which sets a bi-stable 14 so as to open gates 12, 13 which pass an input from a level setting device 10 to pulse train drivers 15, 16 which supply a short train of pulses to each thyristor in bridges 1, 2. Generators 18, 19 produce pulses corresponding to the first pulse of each train which are passed by a gate 20 or 21 to a further gate 22 which rests the bi-stable 14 by the first pulse from 18 or 19 following the termination of the control pulse from 23. Gates 20 and 21 are employed on alternate bursts so that core saturation of interphase reactor 3 is prevented. Long term balance is achieved by means of current transformers 7, 8 and differential amplifier 9.

Abstract: 314,974. Siemens & Halske Akt.- Ges. July 6, 1928, [Convention date]. Addition to 306,406. Central station apparatus. -In a telegraph exchange switchboard as described in the parent Specification currents of the same nature as the message impulses are used for clearing the line. The armature w of the line magnet W at the receiving station rests, when the line is idle, on its marking contact a. Calling up is effected, for instance, by the operation of a relay at the transmitting station by the discharge of a condenser which takes place whenever the transmitter motor is started. In this way the armature w is moved to its spacing contact r, whereupon, the shortcircuit w, a is removed from the preselector magnet V. This magnet is therefore energized and acts to permit the required connection to be made by dialling. The relay V is slow-acting and is not, therefore, affected by signal impulses. When, however, the transmitter motor is switched off, this armature w returns to the marking contact a and the preselector V is de-energized.
