Abstract: 1384580 Television THOMSON-CSF 26 Sept 1972 [18 Oct 1971] 44504/72 Heading H4F  Television camera synchronizing arrangement which enables video signals to be supplied with a phase which leads the synchronizing signals transmitted from a central television station by a variable amount so that video signals from different cameras may be easily mixed with correct phases at the central television station.  In Fig. 1, an input signal from the central television station including mixed line and field sync. signals is received by stage 1 and processed by stages 2, 3 and 4 so that line sync. pulses are delivered at output 83. A camera control 25 includes a line frequency generator 7 whose phase is controlled by the output of a comparator 5 which is supplied with the line sync. pulses from stage 4 and the output of generator 7 via a variable delay 6. Thus the phase of generator 7 is controlled to be independent of the length of the linking cables (shown as broken lines) and may have any desired phase load. Circuit 8 (and circuit 27) in the camera control provides the camera blanking signals, field blanking control signals being supplied to input 82. These field blanking control signals are produced by controlling the phase of a generator 11 delivering a rectangular waveform signal, whose frequency is a multiple of the line frequency F, which is divided 12 to produce signals at F, 2F and 4F at outputs 21, 22 and 23 respectively, the F signal being supplied together with the line sync. pulses at output 83 to a phase comparator 10 whose output controls the generator 11. The 2F output is fed via a variable delay 14 to a binary counter 15 which is reset to zero every field by means of coincidence (AND) circuits 51 and 52 which are supplied with the 2F and 4F signals and the mixed sync. signals from stage 3. The field blanking signal with the desired phase lead is produced by a bi-stable multivibrator 16 in response to the output from counter 15, and in addition to being supplied to circuit 8 is also supplied to a mixed sync. generating circuit 30 together with the 2F signal and a line frequency signal from separator 4. The output from circuit 30 controls the camera view finder.

Wire printers.-A screen-wire print head 9, supported on a frame member 21 which is moved by threaded shaft 17 along the printing line, comprises seven armatures 32 supported on leaf springs 34 which bias attached print wires 10 into printing position, a common electromagnet 36 which holds all armatures in retracted position, and seven individually selected electromagnets 37 which when actuated set up a counter flux and allow the leaf springs 34 to effect impression. The armatures 32 are in side-sliding engageengagement with faces 30 of one polepiece and move in a direction towards and away from the faces 29 of the magnetic cores. This sliding magnetic contact effects as a damper. The selection electromagnets 37 have two windings 37b, 37t, one winding is in series with a condenser 38 and shunted by a resistor 40. When a switch 39 is operated the flux in both windings allows the leaf spring to be released from the flux of the common magnet 36. The changing of the condenser reduces the flow through the coil and after the switch 39 is opened the condenser 38 discharges through the resistor 40 and the flux generated helps the magnet 36 to quickly restore the armature 32.

Abstract: 1,007,508. Temperature alarms. CHARBONNAGES DE FRANCE. Nov. 12, 1963 [Nov. 14, 1962], No. 44687/63. Heading G4N. [Also in Division G1] An A.C. measuring bridge used in a system for operating an alarm or for tripping a protective device in apparatus where temperatures are related to physical conditions has the primary of a voltage step up transformer 8 connected into its output diagonal CD. The secondary of the transformer is taken via a potentiometer 9 to the control and reference electrodes 10a, 10b of a controlled semi-conductor rectifier 10, which rectifier is used to control either an alarm 12 or the tripping circuit 13 of a protective device, or both. The bridge includes a measuring filament which responds to the temperature effects under investigation, such as those occurring in explosion meters, catharometers, and hot wire anemometers, and a compensating filament 2. The potentiometer 9 across the output may be adjusted so that the output circuit trips at any desired voltage. The controlled rectifier 10 is an avalanche effect device, for example a transistor thyratron. It may happen that if the device is not kept continuously in a functional condition it may be accidently operated when the supplies are switched on. To prevent this a bimetallic strip contactor 14 may be connected in the circuit so that the tripping and alarm circuits are kept out of operation until steady conditions are reached.

A predetermined count is effected by a pair of associated shift registers, the second of which is prevented from energizing its last stage and therefore producing an output pulse until the first register has completed a cycle of patterns. The first and second shift registers 20, 50 comprise odd and even units which are pulsed alternately by leads 16, 18. The odd stages are set initially to the pattern shown at the bottom of Fig. 1, which is the same as that corresponding to a count of 15. An " exclusive-or " gate 28 pulses unit E4 whenever the third and fourth stages of the first register are unlike. E4 feeds back to 01. Whenever 04 registers 1 it energizes 40 to re-enter the basic pattern into the second register. Successive pulses are registered as shown in Fig. 2, with a cycle of 15 steps, " 1 " being prevented at intermediate points from reaching D IV in the second register by reentry of the pattern 1000 each time 04 becomes " 1 ". For n stages in each register the cycle is 2<SP>n</SP>-1. A board with insertable pins 71, Fig. 3, may be used to alter the pattern entered into the first register and therefore alter the duration of the cycle. One of several boards may be selected manually (Fig. 4, not shown) or the boards may be selected sequentially at each output from 52, so forming a programme.  Multi-apertured cores of the type described in Specification 899,367 may be used.

Also in Division H1] Roter 1 imbalance signals from 6, 7 pass to a circuit 8 having two outputs 11, 12 respectively representing direction and magnitude of unbalance, the output 12 being connected to a threshold circuit 13 which produces pulses when a threshold is exceeded, the pulses passing to a coincidence circuit 14 and a switch 28 to initiate at 24 a laser pulse from a laser 16 to one of three different correction planes on the roter as selected by a mirror 10 controlled at 9 by the other output 11 of the circuit 8. Each laser pulse burns a set quantity of material from the roter 1. The laser comprises a ruby 15 and a xenon- thallium flash tube 17 in an elliptic cylinder 16, and has reflecters 21, 22 placed opposite the polished ends of the ruby, the reflecter 21 being partially transmitting. The reflecter 22 is separated from the ruby by a polarizer 23, and a Kerr cell or electro-optic crystal 24 which is normally energized from switch 28 to render its direction of polarization perpendicular to that of the polarizer 23, to block reflection between the mirrors 21, 22 and thereby inhibit the production of a laser beam. A capaciter and charging circuit 18 builds up a voltage which passes to the coincidence circuit 14, and when this voltage is sufficiently great and when a pulse from 14 is present, a detector 27 operates an ignition circuit 20 for the flash tube 17. This excites the ruby to a high energy level from which it quickly fluoresces to a lower level, but is able to drop to ground potential and emit a light beam only when the Kerr cell 24 is de-energized. This occurs for a preset time of about 1ms. after flash tube operation by virtue of the detector 27 opening the switch 28, which then enables an imbalance pulse from 14 to de-energize the Kerr cell.
