Title: Electrical synchronisation of rotary shafts
IPC: H04L7/00
Filed: 1943-12-21
Abstract: 586,136. Electric synchronous movements. STANDARD TELEPHONES & CABLES, Ltd. (International Standard Electric Corporation). Dec. 21, 1943, No. 21386. [Class 40 (iii)] [Also in Group XXXV] In an automatic rotary speed control system an activated tuning fork having a natural frequency corresponding to the desired speed of the rotary system, controls a contact to connect intermittently, when the phase difference between the rotary system and the tuning fork exceeds a predetermined value, a potential, corresponding to the phase difference, generated in dependence upon rotation of the rotary system, and continuously varying in the same manner during each revolution of the rotary system, to the grid circuit of a thermionic valve, the anode current of which restores the speed of the rotary system to the desired value. In Fig. 7, motors 37 and 55 driving a transmitter 36 and a receiver 52, respectively, of a facsimile telegraph system in stations remote from each other and connected by wire or wireless, have their speeds controlled by separate tuning forks. Only the fork 61 at the receiving end is shown. This fork operates at a frequency slightly less than the transmitter fork initially, but the energization of its activator coil 76 is controlled automatically to bring the two forks into synchronism. The motors then run synchronously, the receiver motor 55 having a constant lag. The image current is generated at OI which is normally connected through line L to the receiver amplifier RI, but this circuit is interrupted by cain 47 to send synchronizing impulses from oscillator OS which are selected in a combined amplifier, detector and filter RS. The output potential from RS has the waveform of Fig. 8B and a frequency dependent on the speed of the transmitter. This potential is used (a) to operate a line starter clutch 53 and (b) to charge condenser 82 to a voltage dependent on the instant at which brush 68 leaves segment 63. The latter voltage pulses the grid of a tetrode 77, the anode current of which energizes the activator coil of fork 61. The frequency of fork 61 is thereby progressively adjusted until synchronism obtains. Driving contacts 85 of fork 61 control the supply to the screen grid of tetrode 77. The current through these contacts may be reduced by arranging them to control the suppressor grid bias of a pentode serving in place of tetrode 77. Correction for fading, when a wireless link is used, by the use of a valve working under saturation conditions and the.use of impedances to produce the varying potential used to pulse the grid is referred to.

Filed: 1970-05-04
Abstract: 1294728 Digital display systems P S DIVITA E N POWERS and C J WERNETH 4 May 1970 [2 May 1969] 21408/70 Heading G4H A data display device adapted to display a succession of signals from one source or a group of signals from several sources comprises means for periodically sampling the signals and applying the samples to storage and display means, the signals being displayed as a series of lines each on one of a number of different levels. There are a number of input lines 21a-21d each of which receives its signal from a probe applied to a selected point on a circuit. Commutator 20 connects the inputs to corresponding storage and display registers 22. The commutator is controlled by unit 23 controlled in turn by counters 24, 25. Counter 24 delays the transfer of data through the commutator to the registers 22, the delay being measured from a trigger point on the input waveform given by trigger source 28. Counter 25 controls the sampling rate of the input data. The clock pulses used to control the sampling rate may come from an internal oscillator 26 or an external oscillator 27. A spike detector 29 is provided for detecting transitions of signal level shorter than a normal sampling interval and which would otherwise not be indicated. Periodicity comparator 32 monitors the input signals being sampled to ensure that no data is lost due to nonsynchronization of the input and sampling signals. The separate circuits are described in detail.

Title: Improvements in or relating to light detector arrays
Inventor: NOBLE PETER JOHN WELLESLEY
IPC: H04N5/376
Filed: 1968-05-06
Abstract: 1,263,080. Television. PLESSEY CO. Ltd. 5 May, 1969 [6 May, 1968], No. 21434/68. Heading H4F. In a light detector array in which a plurality of light detectors, e.g. photo-diodes, are successively scanned and in which the amount of light falling on each detector is determined by initially charging each detector and detecting the charge remaining thereon after being exposed for a period defining an integration time, the integration time is made different from the scanning rate of the plurality of detectors by delaying the initial charging of each detector with respect to the instant at which it was scanned. In the embodiment described the detectors are arranged in matrix configuration in lines and columns and are successively scanned by means of ring counters, the desired integration time being achieved by delaying the time at which a detector is charged relative to the time at which it is sampled. Although the delay may be continuously variable it is preferably a digital delay which delays a signal which is dependent upon the column or line scanning rate, this delayed signal being fed to a shift register associated with the lines or columns of the matrix array which causes the light detectors of the array to be successively charged, i.e. the integration time of the detectors are varied in multiples of the line or column scan time. Alternatively an input scanning signal (clock signal) may be digitally delayed and fed to a further ring counter associated with the lines or columns of the matrix array operable for causing the light detectors of the array to be successively charged. By having a short integration time less blur will be obtained when the detected image is moving. In addition by varying the integration time the signal level and thus overall sensitivity of the array is varied. An automatic control of sensitivity of the array in proportion to the light level may be provided.

Multeiple cigarette-smoke filters are manufactured by asembling quantities of powdered or granular filter material and lengths of filter-plug material in vertical superimposition and wrapping the vertically superimposed materials to form a continuous rod. The granular material, e.g. charcoal, silica, gel, zeolites or activated alumina, preferably of a size between 10 and 40 mesh (British Standard), is fed from a hopper 12 to holes in a wheel 2 rotating over a retaining plate 13. A smaller, upper, rotating wheel 1 has holes for receiving double lengths of filter-plug material made, e.g. of cellulose acetate, viscose, polyolefin fibres or paper, from a pneumatic conveyer 11. The wheels 1 and 2 are provided with teeth 9 and 10 and are driven by a gear 8. The holes in the two wheels coincide at a single point in line with a tube 15. At this point a corresponding hole is provided in the plate 13 and the filter materials are blown into the tube 15 by a nozzle 16. The filter materials are then wrapped in paper which passes over a roller 18 and is heat sealed at 22 to form a continuous rod which is drawn through a conventional garniture 24 by a garniture tape 23. In a second embodiment (Fig. 4, not shown) the wheel 1 is dispensed with and the filter plugs are delivered from the conveyer 11 on to the surface of the wheel 2, which is rotated intermittently, where a reciprocating pusher pushes each one above succeeding holes in the wheel 2 already filled with granular material and a second reciprocating pusher pushes the materials into the tube 15.
