Filed: 1969-12-01
Abstract: 1285910 Data storage MESSERSCHMITTBOLKOW-BLOHM GmbH 1 Dec 1969 [13 Dec 1968 (3)] 58621/69 Heading G4C An electronic data store consists of two identical storage units each of which comprises a metal plate 20, 22, coated with a homogeneous or rastered layer of semi-conductor or a layer of insulating material on which rastered condenser plates are laid, an electron gun 10, 11, controlled by addressing, 50, and switching, 30, units, and a threshold amplifier 51, 52, which controls the electron gun so as to regenerate the data stored on the plates. The plates store identical data and the arrangement is such that one of the beams systematically scans all the data stored on its associated plate in order to regenerate it while the other plate is available for random access read or write operations. The threshold amplifiers have k (e.g. eight) district thresholds so that any one of k levels may be stored at each addressable location on the plates. During read out the appropriate amplifier 51, 52 is disconnected from the storage plate, the signal is however fed back to the electron gun via a parallel line (not shown) so that read out is non- destructive. In an embodiment, Fig. 3 (not shown), three identical storage plates are employed and a switching unit cyclically connects two of the plates so that the stored data may be regenerated by transferring it from one plate to the other, the third plate being available for read and write operations. In a further embodiment, Figs. 7 and 8 (not shown), two electron beams are associated with each of two storage plates. One of the beams may be used for read out in which case it is coupled to one of the beams associated with the other plate so that the data is re-recorded on the other plate. Simultaneously the other two beams, one for each plate, may be used to read in new data or read out stored data. Each plate may store data by a change in its electrical resistance, in the case of the semi-conductor covering, or capacitively. The store may be used as a program store in conjunction with a computer.

Title: Method of, and apparatus for, recording characteristics of the troposphere

Abstract: 1291849 Echo sounding; phase measuremerit AUSTRALIA DEPARTMENT OF SUPPLY SECRETARY OF STATE FOR 22 Dec 1969 [23 Dec 1968] 62456/69 Headings H3A and H4D In an acoustic pulse-echo system for atmospheric sounding, the echo time and/or duration and/or intensity and direction of reception of upwardly transmitted energy back-scattered from regions of turbulence is recorded. The invention has application in the detection of clear air turbulence, the landing of aircraft, the determination of fog depth and diffusion of pollutants, gun-laying and general tropospheric research. In the Fig. 2 embodiment arrays 1, 2, 3, 4 of transducers are switched by relay group 6 between a transmitting (TX) and a receiving (RX) mode. In the TX mode all four arrays are pulsed together with a selected carrier frequency or frequency band (e.g. a "chirp" signal). In the RX mode the outputs of arrays 1 + 2 + 3 + 4 are summed at receiver 11 and the combined amplitude intensity modulates a facsimile recorder 10 to give e.g. a height/time of day plot. The mean wind velocity deviates the sounding beam and its north-south component is measured by determining the delay or phase difference between the combined output of arrays 1+ 2 and the combined output of arrays 3+ 4 in detector 12. In detector 12, signals 1+ 2 and 3 + 4 are converted to I.F. signals in mixers 14, 18 to which are fed local oscillator signals from fixed frequency oscillator 15 and variable frequency oscillator 19 respectively. The I.F. signals are amplified and limited at 17, 20, then phase compared at 16 to provide an error signal which is low-pass filtered at 21 and locks the frequency of oscillator 19. The phase difference between the two oscillators is then a measure of the wind velocity component and is detected at 22 and indicated at 23. The East- West velocity component is similarly derived at 13 from the phase difference between 2 + 3 and 1+4. In a modification a tristatic or bistatic transmission/reception arrangement is used, e.g. comprising a pair of spaced trans-  ducer arrays with their beams offset from the vertical and energy transmitted from one being received at both on return, whereby Doppler techniques can be used to determine radial components of wind velocity. A transducer may comprise a concrete paraboloid reflector.
Patent GB-651810-A (GB)
Abstract: 651,810. Saw-tooth generating circuits. GENERAL ELECTRIC CO., Ltd. June 11, 1948, No. 15823. [Class 40 (vi)] A saw-tooth voltage generator of the type in which a capacitor is charged or discharged through a resistor and discharged or charged respectively through a grid-controlled valve, has an inductor in series with the capacitor between the output terminals in order to impose on the fly-back positive and negative pulses forming a single cycle of oscillation of much larger amplitude than the saw-tooth wave. The resulting increased velocity during the flyback makes the return trace less visible when the generator is used as a time base for a C.R. tube. In the blocking oscillator shown the capacitor C discharges through a resistor R and then charges negatively as shown at a. This continues until the cathode potential falls below the grid potential, when the capacitor discharges rapidly due to grid current. The resulting current pulse through l2 induces a voltage in l1 which causes the potential of the output terminal 3 to swing negatively as shown by the curve p. The capacitor then recharges rapidly through the valve producing a positive pulse q across l1 and cutting off the valve current. A resistor may be connected across part or all of inductor L to prevent ringing.
