Title: Improvements in or relating to an electrical apparatus for transmitting varying quotations as of stocks or other items
IPC: H04L12/18
Filed: 1929-02-28
Abstract: 307,024. Fabrique d'Appareils Electriques Favarger Soc. Anon. March 1, 1928, [Convention date]. Synchronous movements and synchronism indicators. - Relates to automatic indicating boards for exhibiting stock exchange quotations or other items. Fig. 1<a> shows a multiplexing arangement employing rotary distributors. The actuating and selecting impulse transmitters each simultaneously transmit several groups of signalling impulses over separate line wires 118, 119 which are multiplexed over a line wire 100 and after the impulses have been prolonged they are applied to line wires 44 - - 51 connected to the indicator board. The impulses to lines 44 - - 51 are transmitted over a line 100 from lines 118, 119 by means of rotating distributors 117, 127 driven from an alternating source over lines 102, 103. Fig. 4 shows the construction of a friction clutch 106 through which the distributor shaft 104 may be driven and a modification of the escapement type speed controlling device shown in Fig. 1a. The distributor shafts 104, 110 carry conducting rings 125, 132 with insulating insets 126, 177. Relay 173 is energized except when the brush 124 engages an insulating inset and opens the synchronizing circuit from the battery 175 through relay 176 and line 102 to the brush 168 which if not on an insulating inset 177 completes the circuit through relay 180. With phase displacement, relay 176 is energized and operates a slow release relay 140 which breaks the transmitting circuit at contact 139 and the impulse generating circuit at contact 166. Contacts 189, 190 light an indicating lamp 194 and operate a relay to prevent the transmission of selecting or actuating impulses. At the receiver relay 180 operates and, closing a locking circuit at contacts 182, operates a stepping magnet 136 and an indicating lamp 187 at contacts 183. Relay 140 temains energized until the next insets 126, 177 are reached when it de-energizes and a further actuation of relays 176, 180 is effected if the phase displacement is not corrected. If synchronism exists these relays remain de-energized and transmission proceeds.

IPC: B41F21/08
Filed: 1951-03-20
Abstract: 700,116. Printing machines. FABER & SCHLEICHER AKT.-GES. March 20, 1951 [March 30, 1950], No. 6604/51. Class 100 (2) Rotary machines; gripper mechanism.-In apparatus for conveying sheets of paper between two rotary printing couples, employing chains provided with gripper systems which take over the sheets of paper from the grippers on the impression cylinder of one couple and transfer them to grippers on the impression cylinder of the other couple, the chain gripper systems are movable relatively to the chains, a device being provided on each impression cylinder for effecting such movement during the transfer of a sheet to effect proper registration of the sheet. As shown in Figs. 6 and 8, the gripper mechanism 108 is mounted on a carriage consisting of bars 104, 105, 106 having rollers 103 thereon which run in tracks 101, 102. The gripper carriage is connected by draw bars 111, 112, to chains 109, 110, the draw bars allowing the carriage to move relatively to the chains. Relative movement, for the purpose of correctly positioning the grippers with respect to an impression cylinder 115, is achieved by the action of fingers 116 on the cylinder 115, on fingers 113, 114 on the gripper carriage. causing the gripper carriage to tilt, such tilting being allowed by the provision of a spring biased, movable portion 117 of the track 102. In a second embodiment (Figs. 10 and 12) the gripper carriage consists of two bars 201, 202, with rollers 203, 204 on which it runs between guide rails 205, 206. As long as the chain 207 runs in a straight line the gripper carriage is coupled therewith by a roller 208 and a link 209, located on the chord of the two rollers 203, 204. When the path of the chain and gripper carriage becomes curved the link 209 drops, Figs. 13 and 14 (not shown) to release the gripper carriage from the chain. To drive the gripper carriage during the revolving of the chain a lever 215 is mounted on a shaft 214, a spring biased forked lever 216 being connected with the lever 215 by a draw-spring 217, the forked part of the lever 216 carrying the gripper carriage by means of a roller 210 mounted on the gripper carriage. Relative movement between the gripper carriage and chain is thus allowed under the action of fingers 211, 213 on the gripper carriage and impression cylinder respectively. In a third embodiment, Figs. 15 ... 20 (not shown) instead of the carriage being normally driven by the chain by means of the roller 208 and link 209 it is carried in roller cups on a long chain link.

Filed: 1972-02-14
Abstract: 1382483 Transistor emitter follower amplifiers RCA CORPORATION 14 Feb 1972 [16 Feb 1971] 6765/72 Heading H3T An emitter follower 10 has negative feedback from collector to emitter through a path comprising two B insensitive current amplifiers 18, 26 and a common emitter amplifier 16. As shown in Fig. 1, the current feedback amplifiers are unity gain current mirrors. The collector voltage of the emitter follower is held close to the collector supply and the current mirrors provide a current at the collector of 20 equal to the collector current of 14. Any difference between this and a predetermined constant current supplied by resistor 30 is fed to the base of transistor 16 to maintain the collector current of transistor 14 substantially constant. Accordingly, the input signal may swing between values close to the supply voltages without substantial change in the voltage drop between base and emitter of transistor 14. In Fig. 2, the two current mirrors are arranged in parallel so that if the current in 24<SP>1</SP>, representing the current in 14<SP>1</SP>, is different from the current supplied by resistor 38, the difference is fed back via 32 and 16<SP>1</SP>.

Filed: 1933-03-07
Abstract: 413,065. Automatic exchange systems. SIEMENS BROS. & CO., Ltd., Caxton House, Tothill Street, and DIXON, R. G., 162, Westmount Road, Eltham Park, both in London. March 7, 1933, No. 6888. [Class 40 (iv).] In a single-motion group selector provided with two sets of double-ended staggered wipers co-operating with four levels or rows of terminals W, X, Y, Z, the level to be used is determined by a preliminary digit which may effect wiper-selection or movement of the wipers through 180‹ or both. A second code selector driven by an electromotor DM and controlled by common apparatus including a digit switch DS is shown. After responding to the preliminary digit, the digit switch moves to a subnormal position and in accordance with the setting digit marks the group to be searched over by the selector, a single set of marking wires being connected to the appropriate terminals in the four levels. In the case of the level W, since no preliminary operation is required in the selector, a preliminary digit is unnecessary provided the setting digit always comprises a sufficient number of impulses to step the digit switch beyond its subnormal position. In all cases the setting digit may comprise up to 15 impulses. For the preliminary digit 1, relays G, P(i) energize over wipers DS 3, 4 and lock on the relapse of dialling relay C. Latch magnet LM operates and the selector rotates through 180‹ to the first terminals of levels X, Z, when test relay T pulls up in series with TA(ii) P(ii), and connects up TA(i). The windings of TA, P are in opposition, so that the former does not operate while the latter now falls back and in turn disconnects T. The digit switch steps to its subnormal position 5, in which relay E operates and completes a fresh circuit for dialling relay C in readiness for receiving the setting digit. If the preliminary digit is 2, relays G, F energize, and the digit switch moves to position 5 on the relapse of C. Relay E operates and connects up wiper-switching relay WS. If the preliminary digit is 4, relays F, P energize and the selector rotates through 180‹ as described above, while in addition wiperswitching relay WS energizes upon the operation of E. If the preliminary digit 3 is used to determine the level W, none of relays G, F, P energizes, and the digit switch merely advances to position 5. Otherwise, the digit switch advances to this position in response to the first five impulses of the setting digit, the group being determined by the succeeding impulses. After the setting digit has been received, the selector searches in the usual manner for an idle outlet in the marked group. If no idle outlet is found, the selector stops on the last terminals of the effective level, test relay T energizing in series with LC, which sends back a signal to the register-controller to effect rerouting and initiates release of the control circuit. The overflow meter of the appropriate group is actuated over one of wipers DS 4-7 in accordance with the condition of G, F. Specifications 388,173 and 411,456 are referred to.

Filed: 1973-02-14
Abstract: 1417325 Digital transmission; synchronizing INTERNATIONAL STANDARD ELECTRIC CORP 14 Feb 1973 [14 Feb 1972] 7186/73 Heading H4P In a method of determining 'slippage' along a transmission line, a check signal is transmitted either along the same or different channel to the data, signal values differing in adjacent intervals in a determined manner which provides check on reception that the sequence is correct, any departure being indicative of slippage. A series of alternate 0 and 1 check signals are transmitted as additional bits parallel or serial to data items, i.e. bit, word, or block, the signals on reception being fed through a terminal E to flip-flop FF and one input of exclusive OR gate EO, also to a clock generator TG. The state of FF is changed by clock signals T which are synchronized with and have double frequency of check signals and may be derived from check signals. Output K<SP>1</SP> is shifted relative to input Ke by one clock unit and inverted. A slippage signal S appears only if a received signal is not in agreement with the inverted previous check signal. In an alternative arrangement, a cyclic sequence of +1, 0, -1 is used which are represented by 3 pairs of binary values developed by a circuit, Fig. 4 (not shown), the fourth pair not being used in the arrangement, but may be used for other purposes, not particularly disclosed. In Fig. 5, the check signal is applied to comparators V1, V2 also to clock generator TG whch generates signals for the expected period of slippage, and controls a counter Z; this delivers a sequence of signal elements RKS which correspond to, are synchronized, but may be out-of-phase with received check signals. Modulator M develops outputs n + 1, n - 1 which are compared in V1, V2 and in the event of no slippage, outputs do not appear at A, W. However, if there is erroneous repetition V1, V2 will have different values from the modulator output hence a slippage signal will appear on A, W.
