Title: Improvements in electric display indicator systems
IPC: B61L25/04
Filed: 1959-12-23
Abstract: 880,078. Electric selective signalling systems. GENERAL RAILWAY SIGNAL CO. Dec.23, 1959 [Jan. 26, 1958], No. 43676/59, Class 40 (1). An electric display indicator system includes a plurality of indicator devices settable to different display positions in response to setting control potentials applied thereto and each having contacts actuated in accordance with the setting taken up by the indicator in response to such potentials, and means for applying setting control potentials to at least one of said indicators in dependence upon the condition of contacts pertaining to another indicator whereby to transfer the setting of said other indicator to said one indicator. As described data applied to lines 1CB to 5CB, Fig. 1A, can be selectively entered into any one of a rectangular array of indicators 1D1A to 1D1C, 2D1A to 2D1C by closing the appropriate row read-in contact R1A, R1B or R1C together with the appropriate column read-in contact 1COB or 2COB. Each indicator comprises a motor-driven shaft, for positioning a character bearing tape, and a number of switch contacts, a different combination of which are closed for each of the shaft's ten possible positions. The electrical connections are such that when an indicator is selected, by closing the appropriate row and column selecting contacts, its motor is energized until its shaft is in such a position that its contacts have assumed a pattern of open and closed states corresponding to the pattern of input signals applied to lines 1CB to 5CB. Data registered in a first selected row of indicators may be transferred to a second selected row by depressing a transfer button TB simultaneously with the closure of an appropriate one of three row read-out contacts ROA, ROB and ROC, and of the appropriate one of the three row read-in contacts R1A, R1B and R1C. The result of this is that potential is applied to all the column conductors 1 to 5 via resistors 1R to 5R and 11R to 15R, which potential is connected direct to earth via the closed contacts of the indicators in the selected read-out row whereby the only column conductors whose potentials are sufficiently high to drive a motor are those corresponding to the open contacts of the indicators in the selected read-out row, which combinations of potentials the indicators in the selected read-in row seek (or follow) in the usual way. In a second embodiment the combinational code is replaced by a one-out-often code, and in a third embodiment transistors are used in the motor driving circuits whereby the potentials that have to be switched by the switch contacts are reduced.

Title: Apparatus for synchronising a mechanical oscillatory system
IPC: G04C11/08
Filed: 1974-10-14
Abstract: 1480801 Electronically controlled timepiece H JAUCH 14 Oct 1974 [24 Oct 1973] 44332/74 Heading G3T In a timepiece driven by mechanical energy storage means (spring), the oscillatory system (e.g. balance or pendulum) is maintained at substantially constant frequency by synchronizing timing pulses derived from a quartz crystal controlled oscillator by a frequency divider, a phase and frequency comparison being made between the timing pulses and an alternating voltage derived from movement of the oscillatory system to produce a regulating signal which is used to apply a regulating torque MR to the system. In Fig. 1 a frequency and phase discriminator 13 (e.g. comprising a pair of transistors in series forming an AND gate as in Fig. 5, (not shown)) compares the phase and frequency of a voltage induced in a coil 14 - by movement of a magnet 5 fixed to a balance 4 - with that of a timing signal from crystal controlled oscillator 1 via a frequency divider 2. The resulting output of the discriminator 13 is applied to the coil 14 circuit as a regulating signal which causes a greater or lesser breaking effect on the balance movement depending upon deviation from synchronism. Thereby synchronism is maintained. The transducer coil 14 may be electrically loaded in the positive or negative half cycles of the mechanical oscillation and produce signals in the negative or positive half-cycles respectively. In an another embodiment Fig. 2 (not shown) instead of using a battery 9, the electronic circuitry is energized by the rectified and smoothed A.C. output of a second coil (11) co-operating with a second magnet (10) on the balance. In an embodiment Fig. 3 (not shown) a single coil and magnet serves both as a regulator and as a 'dynamo' to provide electric power for the circuitry. In an embodiment Fig. 6 (not shown) the oscillation amplitude is stabilized by a transistor (62) and the discriminator comprises a transistor (34) in series with a diode bridge across a diagonal of which a single regulator coil (36) is connected. In an embodiment Fig. 8 (not shown) there are additional coils (83) (84) called 'work' coils which are energized to accelerate or retard the balance respectively, by electromagnetic action or by coupling an additional balance spring. In an embodiment Fig. 9 (not shown) the result of the phase comparison is used to control a servo motor (95) arranged to influence the frequency of a mechanical oscillatory system in a timepiece.

Abstract: 1,028,018. Facsinicle communication systems. RANK XEROX Ltd. Nov. 11, 1963 [Nov. 19, 1962], No. 44368/63. Heading H4F. [Also in Division H1] Information presented in the form of an electrostatic charge pattern on a dielectric member 18 is read out by means of a cathoderay tube N in which the beam 16 is scanned over an array 12 of conductive pins, which pass through the tube wall, to induce a current varying in accordance with the information in the circuit of a backing electrode 20, a corresponding signal resulting therefrom in a resistor 22 being applied through an amplifier 23 to the amplifier 66 of reproducing apparatus where the signal modulates the grid of similar cathode-ray tube 41 to cause the information to be recorded in an identical pattern on a second dielectric member 48. The information may be impressed on member 18 by known means, e.g. an alpha-numeric electrostatic printer, and the recorded information on member 48 may be developed and rendered visible by known means. As illustrated, cathode-ray tubes 11 and 41 are each provided with a line array of pins and the beam is scanned in one direction only along the array. Members 18 and 48 are in the form of webs and are traversed uniformly past and closely adjacent the ends of the pins. According to another arrangement (not illustrated) a two-dimensional array of pins may be used with the beams subject to scanning in two directions. Scanning generators 33, 63, synchronizing pulse generators 31 and synchronising pulse separators 34, 64 are arranged in association with both the read out and recording apparatus, and switches 21, 51; 32, 62; 35, 65 are provided so that the functions may be reversed to permit the system to operate with two-way working. In a first modification of the read-out apparatus, Fig. 4 (not shown), member 18 is in the form of a conductive drum bearing a photo-conductive layer. As the drum rotates, in a first position it is subject to a precharge, in a second position it is exposed to an optical image and in a third position the image is read out by a cathode-ray tube arranged as in Fig. 1. In a second modification, Fig. 5 (not shown), the read-out cathode-ray tube is constructed to operate in a manner similar to an orthicon camera tube in which the signal is produced in response to electrons returned within the tube from the pin electrodes.

A cascode amplifier has an input coupling capacitor Ck and negative feedback via a resistor R g , and no resistors connected to the input electrode having a value lower than that of the negative feedback resistor Rg. As shown, a first cascode amplifier comprising transistors I, II, supplied from the output of a vidicon or plumbicon pick-up tube (not shown) is coupled via a further cascode amplifier III, V to an output terminal. Negative feedback is taken from point K on the output load resistance R 1 , R d  via a screened resistor R g ; the operating point of the first transistor I is thus determined by the voltage at point K. The screen of resistor R a  is driven from an emitter follower III so as to minimize the effect of self-capacitance. The negative feedback resistor Rg is preferably greater than one Megohm so as to ensure a high input impedance. The junction transistors may be replaced by nuvistor valves (Fig. 1, not shown), or by field-effect transistors. In Fig. 2 (not shown), transistor V is omitted and the input terminal is coupled to transistor I via a further emitter follower.
