Filed: 1971-11-23
Abstract: 1369463 Video distribution systems PROCESS PERIPHERALS Ltd 8 Jan 1973 [23 Nov 1971] 54397/71 Heading H4R In a communication system in which a central station is connected by individual cable conductors to outer stations so as to transmit video information with line and frame sync intervals to raster-type displays, the outer stations respond to the incoming information to transmit data to the central station over the same distribution conductor during the frame or line sync interval. At each outer station the video sync signals are separated at 15 and fed to timing generator 16, control logic 24 and remixed at 30 with the separated video before passing to the display monitor. The timing generator 16 detects the first broad pulse of the sync signals, counts nine pulses from the second, then produces an output trigger pulse at the start of each of the following nine line periods corresponding to the flyback period over which data is to be transmitted back to the central station. A blanking signal is generated during this whole period and mixed with the video at 19 to prevent the data appearing at the monitor. The data is entered via keyboard 20 (or tape reader), stored 22, then transferred by byte to store 23 which is controlled by timing pulse generator 16 and keyboard strobe signal to gate the data to driver 25 and thence back along the line. The data is in the form of 1 start, 1 parity and seven bits as positive pulses of 45 �sec. duration superposed on the 64 �sec negative line sync pulses. The stations may include a facility to display the output of store 22. At the central station (Fig. 4, not shown) data from any of 64 outer stations is stored 41, interrogated to see if the first data line is new and read-out accordingly to a unit (44) having direct memory access to computer. Address signals from unit (45) identify the station involved, and the whole operation is controlled (43) by a logic unit (43) according to line sync (46). In a modification (Figs. 5a, 5b, not shown) the sync pulse (14) in the sync interval (13) is short (500 n sec.) but is extended at the outer stations for display and is used to gate the data down the line as above.

Title: Apparatus for Measuring the Extent to which Dosimeters have been Irradiated
IPC: G01T1/105
Filed: 1966-12-13
Abstract: 1,156,179. Dosimeter read-out apparatus. SOC. DE REALISATIONS MECANIQUES ET ELECTRONIQUES CEHESS. Dec. 13, 1966 [Dec. 13, 1965], No.55749/66. Heading G1A. A dosimeter glass is read-out by illuminating it with a single flash of ultraviolet light and measuring photo-electrically the resultant fluorescent light emitted by the glass. A portable device is described with which the original dose of irradiation received by the glass from a radio-active location, can be measured. The glass is inserted into a recess (5) in a drum (4) which is movable within a housing (2, Fig. 1, not shown). A lever (3) is turned to rotate the drum to bring the glass in line with a flash-lamp (9), and a photo-multiplier (15) equipped with an orange filter (14). A button (29, Fig. 7, not shown), is pushed and kept pressed during the measurement. The flash-lamp is ignited and the resultant light pulse illuminates the glass. The pulse of fluorescent light produced is detected by the photo-multiplier and converted into a continuous current the value of which is representative of the original irradiation dose received by the glass, and which is indicated on a microammeter calibrated in roentgens. The push button (29) is then released. The circuit for the flash-lamp (17, Fig.2, not shown), is supplied by a D.C. source followed by oscillator, transformer (T) and rectifier, so as to charge up two parallel-connected condensers (18, 26). Pressing of the push button (29) to start the measurement process results in the switching of a thyristor allowing discharge of the condenser (26) into the primary of a transformer (T2). The high voltage pulse in the secondary of the transformer causes ignition of the flash-lamp. The fluorescent light from the glass is detected by a photo-multiplier, Fig. 3 (not shown), associated with capacitors and resistors to provide a linear response. The output pulse from the photomultiplier on line 65, Fig. 4, charges up a capacitor 66, 67 or 68 (which has previously been selected when setting the sensitivity of the measuring device). The capacitor discharges and the resultant pulse is amplified by transistors 70<SP>1</SP>- 72, before being stored by circuit 77 - 79. The energization of relay 76 by closure of start switch 29 causes switching, after a slight delay while current in the coil increases, of contact 75 and the condenser 78 is thereby isolated and controls the electro-meter valve 80. This causes a disturbance in the equilibrium of differential amplifier 82, 83 resulting in a continuous current through micro-ammeter 84 directly representing the dose received by the dosimeter glass. A potentiometer 85, 86 or 87 is selected in correspondence with the capacitors 66-68 to set the sensitivity of the scale of the micro-ammeter. Potentiometer 97 provides for zero adjustment. The supply circuit, Fig.5(not shown), and the circuit of the switch for on/off, scale sensitivity selection or battery check, Fig. 6 (not shown), are illustrated.

Abstract: 1434063 Detecting objects by radiation WESTINGHOUSE ELECTRIC CORP 3 Dec 1973 [5 Jan 1973] 55896/73 Heading G1A A method and apparatus for detecting a handgun or a bullet therefore in an object include means for: subjecting the object to 200-400keV radiation; monitoring the transmission characteristics of portions of the object corresponding in size with a gun or bullet; and evaluating signals representing the transmission by comparison with reference signals representing a gun or bullet. Objects such as luggage L or parcels on a conveyer C are carried past a monitoring station 10, where they are scanned by a fanwise beam of x-rays in a vertical plane from a source 20 containing radio-active material 28. Attenuated radiation, received by a vertical array 32 of scintillation crystals SC1 &c. with photo-multipliers PM1 &c., stimulates signals which, processed by a circuit 40, provide outputs to alarm circuits 50. In the simple arrangement of Fig. 2, each sensor produces in the amplifier 42 output a noise-free voltage representing the mass in the path of that sensor for comparison in a circuit 44 with a reference threshold signal R from a source 43 representing a gun or bullet, to activate an alarm circuit 50. The magnitude of the reference signal R is derived from statistical probability-distribution curves for distinguishing guns or bullets from other articles commonly carried in luggage. Figs. 5-8, (not shown). In a signal processor of finer discrimination, Fig. 9A, signals from a bullet threshold circuit BT, a first gun threshold circuit GT, and a second gun threshold circuit GT<SP>1</SP> fed by an integrator I, all related to the output of each sensor, are correlated by gates OR1 &c. and Al &c. to provide signals representing the extent of the suspected article both vertically and in the line of travel. A further arrangement for repetitive sampling of each detector output is mentioned. In another scanning arrangement Fig. 4 (not shown) a flying-spot scanner (100) comprising an x-ray tube (102), a vertical slit collimator (104) and a rotating slotted disc (106) scans the object (L) vertically, directing radiation towards a vertically-extending single detector strip (110) e.g. a CdS or ionization detector.
