Title: Apparatus for synchronizing a television picture signal source
IPC: H04N5/073
Filed: 1963-11-12
Abstract: 1,012,787. Automatic phase control systems. FERNSEH G.m.b.H. Nov. 12, 1963 [Nov. 13, 1962], No. 44589/63. Drawings to Specification. Heading H3A. Remote television camera installations are synchronized relative to a control station master pulse generator by phase comparing the latter with horizontal synchronizing pulses received back from a distant camera unit as part of the video signal to derive a control voltage which varies the phase of a reference signal transmitted to the camera unit to control the timing of a pulse generator there which determines the phase of the camera horizontal synchronizing scan. The reference signal may be a sine wave produced from the master pulse generator via a division by two frequency divider. The phase shifter at the control station may be two transistor monostable circuits in cascade each triggered by the negative going trailing edge of an applied pulse and each developing pulses of duration determined by a control voltage applied to the bases of one transistor of each monostable circuit, and each duration modulated pulse being differentiated to form negative going pulse spikes before being passed on. At the camera unit the sine wave, received by cable or radio, controls the synchronizing, by a flywheel sync. loop of an oscillator of frequency four times the sine wave frequency (i.e. twice the horizontal scan frequency), controlling through a pulse generator the camera scanning. At the control station a manually adjustable phase shifter may be in series with the variable phase shifter to increase the range, without decreasing the sensitivity of the phase control. Vertical scan control.-Vertical scan synchronizing pulses may also be received back at the control station from the camera (as part of the video signal) and be phase compared with master vertical pulses from the master pulse generator to derive a control signal which actuates a switch so that the frequency of an auxiliary oscillator differing slightly from that of the normal reference sine wave is transmitted instead to the camera unit until vertical synchronizing is reached whereupon the switch reverts to transmitting the normal reference sine wave. A film or slide, or magnetic recording scanning unit may replace the camera unit. A number of remote units may be controlled from a central control station.

Abstract: 974, 011. Electric selective signalling systems. GENERAL ELECTRIC CO. Ltd. Dec. 6, 1962 [Dec. 12, 1961], No. 44528/61. Heading G4H. In a shaft 1, Fig. 1, digitiser using two digitisers 3, 4, of the type described in Specification 863,027, which is referred to, coupled together by a 16 to 1 reduction gear 5, the "coarse" digitiser 4 which has a five-bit output which therefore indicates the particular half-rev of 32 half revs in which the shaft 1 lies is zeroised behind its theoretical position by an amount equal to a 90 degree displacement of the shaft 1, and the signals produced by it are "corrected" under the control of the "fine" digitiser 3 in such a way that errors which might arise from imperfections in the gears are eliminated. Since the output of coarse digitiser 4 indicates in which half-rev the shaft 1 lies its least significant bit should coincide with the most significant bit of the "fine" digitiser 3 and it is this redundancy that is used to "correct" the signals from the "coarse" digitiser 4 which is deliberately arranged so that its output changes 90 degrees of shaft 1 too late. In operation first the "fine" digitiser 3 is sensed its output being converted from monophylic binary to pure binary 9,11,12,13 and then being passed via an adding arrangement, where zero is added, to arrive at output leads 31-35 unmodified. Secondly the "coarse" digitiser is sensed, its output being converted from monophylic binary to pure binary, as before, and then either 1 or 0 is added 19 depending upon the most significant bit from the "fine" digitiser 3 which is stored in a trigger 40, and the resulting sum on leads 32-35 (the least significant bit being ignored) represents the desired corrected output from the "coarse" digitiser. Specification 920,535 also is referred to.

Automatic control of register. SIEMENS-SCHUCKERTWERKE A. G. Dec. 1, 1964 [Dec. 4, 1963], No.48841/64. Heading G3R. In a registration control system the amplitude of the pulses derived from scanning masks on a web is maintained constant by comparing the amplitude of the pulses from a correcting device with a desired value and controlling the correcting member accordingly. As shown, a paper web 1 carrying register marks 2 is scanned by the light from a source 3, the reflected light pulse being received by a photo-cell 7. The photo-cell current pulse is fed through a pre-amplifier 8 and a correcting member 9 to an amplifier 10, the output voltage of which is applied to charge a capacitor 19 across the input to an amplifier 11, when the output voltage is greater than the voltage of a Zener diode reference device 14. The output of the amplifier 11 adjusts the correcting member 9 to maintain constant the amplitude of the output voltage pulse from amplifier 10. When the output voltage of amplifier 10 reaches the response boundary value of a bi-stable trigger stage 12 a pulse P1 is fed to a registration control device (not shown). The stage 12 also controls an arrangement 20 discharging the capacitor 19 when the voltage pulses from amplifier 10 suddenly fall below the response value of the stage causing a reduced input to the amplifier 11 and an increase of the output from amplifier 10. A switch circuit 15, responsive to an evaluating device 18, is arranged to short-circuit the amplifier 10 when a picture or type is passing beneath the web scanning arrangement.

Abstract: 454,653. Counting apparatus. HANDLEY, J., and SUCKLING, C., 22, Sandringham Road, and SUCKLING, R. H., 19, Heather Gardens, both in Golders Green, London. Jan. 3, 1935, No. 182. [Class 106 (i)] Counting mechanism particularly for use in totalizators operated by electrical impulses comprises step-by-step operated primary mechanism, a secondary mechanism in series therewith and intermediary mechanism, including a torsion spring, cam disc engageable with a detent, and associated with a fixed ratchet wheel, so arranged as to permit the primary mechanism to over-run the secondary mechanism and temporarily to store the impulses causing the over-run. In the form shown an electromagnet 1, Fig. 1, receives impulses to be counted and actuates a spring controlled armature 2 that carries a, pawl 4 to impart a unidirectional rotation to a ratchet wheel 5. The ratchet wheel 5, Fig. 3, is secured to a hollow shaft 100 journalled on a fixed spindle 101 the other end of the shaft 100 carrying a disc 7 with a projecting lug 106 formed with a cam notch 105, Fig. 4. To the shaft 100 is connected the inner end of a spiral spring, 102 the outer end of which is secured to a housing 103 fixed on a spur wheel 9 loose on the shaft 100. The wheel 9 carries a pawl 8 normally engaging the cam notch 105 under the torque of the spring. In operation the pawl 8 ratchets over the teeth of a fixed wheel 10 by following up the disc 7. If the disc 7 over-runs, the pawl rides on the rim of the disc thereby storing the impulses and finally re-engages the notch 105. The movement of the wheel 9 is transmitted through a pinion 12, Figs. 1 and 2, and gearing to the units indicating disc 17. Impulses from two mechanisms may be transmitted to the units disc 17 the pinions 12, 12a being connected to a differential gear 13 and wheels 14, 15 to the units spindle 16.

Abstract: 1441388 Vehicular control circuits STANDARD TELEPHONES & CABLES Ltd 16 Oct 1973 [3 Oct 1972] 45470/72 Heading B7H [Also in Division H1] A control circuit for electrically powered vehicular accessories 3 includes fluid actuated relays 4 which control power supply to the accessories, the relays being controlled by fluid supply switches 7. A pneumatic or hydraulic reservoir 8 is connected via a control panel 6 to an extruded bundle of pipes 9, individual pipes being respectively connected to one relay and fluid supply to each pipe being controlled by a switch 7. Each relay includes a domed and an annular electrical diaphragm contact 24, 26 which come into contact when fluid pressure is applied to the convex side of the domed diaphragm 24. Diaphragm 24 may be dimensioned so that pressure has to be continuously applied to maintain contact and so that it will remain in contact with the annular diaphragm after only an initial pressure pulse. In the latter case pressure is applied to the other side of the diaphragm to break contact. In one type of relay (Fig. 3, not shown) the domed diaphragm is of the non-holding contact type and whilst in its undeflected state defines, with a seating in the relay housing, a fluid reservoir. This reservoir is connected to a pressure inlet via a flow control valve and pressure builds up within the reservoir until the domed diaphragm is deflected. The reservoir is then connected to exhaust and the diaphragm snaps back and remains there until the pressure builds up again in the reservoir. Interlocked or sequenced switching of components may be effected by the incorporation of fluid logic devices.
