Abstract: 1294348 Cathode-ray tube circuits MARCONI CO Ltd 20 Aug 1970 [21 Nov 1969] 57016/69 Heading H4T In a raster scanned cathode-ray tube arrangement the beginning of each line scan is synchronized to the frequency of ripple in the E.H.T. voltage supply to the tube. With this arrangement "waves" in the scanned lines which, in the absence of the invention, would appear in different positions in different lines as shown in Fig. 1a, are caused to appear in similar positions in each line as shown in Fig. 1b. This allows the spacing between the lines to be a minimum and results in an increase in the amount of information which may be stored on a target or an increase in the definition of a display. Fig. 2 shows an embodiment in which the output of a H.F. oscillator 1 (which provides the E.H.T. supply for the tube via rectifier 2, smoothing circuit 3 and terminal 4) is divided down to line scanning frequency by a divider 5 and employed to synchronize the operation of the line deflection generator 6 connected to deflection plates 7. In a modification, it is stated that the E.H.T. generator could be driven by a signal derived from the deflection generator in such a way that the ripple on the supply voltage to the tube and the deflection signals are synchronized at predetermined points throughout the raster.

Title: Radar system

Filed: 1969-12-04
Abstract: 1286297 Pulse radar MESSERSCHMITTBOLKOW-BLOHM GmbH 4 Dec 1969 [13 Dec 1968] 59342/69 Heading H4D A radar produces two equal duration contiguous range-gates, the overall duration and location thereof corresponding to an initial target area and has means for varying the timing thereof such that the energy content of echo pulses received therein is equalized and also has means to reduce the range gate duration equally to a total duration equal to a wanted target echo while retaining the equal energy distribution. An air-to-sea missile has an active radar which is switched on after it has flown towards the target for a time t 1 . Having been launched from a known range E, Fig. 1, the missile has a target area t 1 v 2  to search, v 2  being the target velocity, thus the initial timing and duration of the range gates is known at launch. The active radar, Fig. 7, of the missile comprises a transmitter T feeding an aerial A and a generator G providing a sawtooth waveform. The echo pulses are received by A, or a second aerial and pass to switching networks Z 1  and Z 2 . The networks are opened by the range gate pulses S 1  and S 2  produced by generators VS 1  and VS 2 . These are triggered by blocking oscillator SP which is triggered by a voltage from comparator K which has one input connected to the sawtooth generator G and the other connected to the output of an integrator J 2 . Initially since the switch contacts r 1  are all open the output Eg of the integrator J 2  is determined by a potentiometer chain W 1 , W 2 , W 3 , which provides a voltage to the comparator K, representing the distance E 1 . The sawtooth generator has a variable bias which is governed by the target area radius t 1 v 2  and which shifts the waveform by a corresponding amount upwards, Fig. 8. The first range gates are thus produced to cover the target search area. When echo pulses are detected the summing output # 1  of amplifier D switches relay R 1  and the switch contacts r 1  all close. The output of integrator J 2  now becomes representative of the difference between the energy received during the two range gate periods, this alters the timing of the range gate triggering until the energy is equalized. After a delay determined by capacitor C, the relay R 2  is operated and switch contacts r 2  are changed. This brings into operation range gate generators SV 1  and SV 2  which produce shorter range gates than previously. The whole process may be repeated until the range gates are the same width as the remaining echo, either by using successive narrower range gate generators or by using a variable width generator. At this point tracking is initiated. The system is stated to eliminate all but the largest echo pulse.

Abstract: 1,256,370. Flow regulator. EMERSON ELECTRIC CORP. Dec.23, 1968 [Jan.5, 1968], No.61205/68. Heading G3P. With flows below a preset maximum, pilot fluid entering chamber 66 above rolling diaphragm 42 via port 102 in main valve stem 47 and axial groove 65 in sleeve 63 (see Fig.2) can escape to the main outlet 5 via the interior of sleeve 63, pilot valve 23, 114 (which is open due to flow sensitive disc 21 being in a lowered position) and passages 78, 80, 82, 84. Inlet pressure can therefore unseat the main valve member 41. When the flow approaches the maximum, disc 21 closes the pilot valve and the resultant pressure build-up in chamber 66 moves valve member 41 towards its seat. The consequent reduction in flow will tend to open the pilot valve and a stable balance point will eventually be reached. Upon total closure of the main valve, the final movement of member 41 is retarded due to the bottom of groove 65 coming above a wearresistant damping ring 110. The maximum flow is set by adjusting the axial position of the pilot seat through handwheel 98 and stems 91, 96, the selected position being read against scale 99. A magnet 28 movable with disc 21 serves to indicate the flow rate at 29. Hollow annular body 52 serves to lighten the main valve member in the liquid without actually making it buoyant. A bleed orifice 100 from chamber 66 allows air removal at start-up, and a manual valve 81 permits total shut-down. Hollow stem 22 balances disc 21 against variations in upstream and downstream pressures. The disc 21 may alternatively be downstream of the main valve member, and the pilot circuitry may be external.
