IPC: G01S13/58
Filed: 1966-06-10
Abstract: 1,113,583. Doppler radar. MULLARD Ltd. 10 June, 1966, No. 25885/66. Heading H4D. The Specification describes a CW Doppler Radar suitable for determining the speeds of vehicles and whether they are approaching or receding, wherein a transmitter 5 produces a signal which is radiated via directional coupler D and circulator C by antenna A. Part of the transmitter power is diverted by coupler D to a generator E which produces a local oscillation with a frequency differing from that transmitted by a known amount F. The echo signal, frequency shifted by fd is mixed in mixer M with the output of generator F to produce an I.F. signal of frequency FŒfd depending on whether the target is approaching or receding. To eliminate signals from stationary objects, a narrow band rejection filter RF, rejects the signals of frequency F, and the Doppler shifted signals are fed to a bank of band filters PF, each feeding a speed indicator I via a detector R. In the embodiment of Fig. 2 (not shown), a first antenna directs a beam down one traffic lane and a second antenna directs a beam in the opposite direction down the other traffic lane. The same transmitter and generator are used for both beams.

Title: Improvements in or relating to equipments for use with electronic monoscopes
IPC: H04N5/228
Filed: 1949-10-11
Abstract: 675,520. Generating television signals. GENERAL ELECTRIC CO., Ltd., KIRKNESS, R. H., and NIXON, R. D. Oct. 10, 1950 [Oct. 11, 1949], No. 26103/49. Class 40 (iii). Apparatus for generating video signals corresponding to a picture or pattern on the screen 2 of a monoscope, comprises means for blanking the video-signal output from the monoscope to the black level during the lineflyback intervals, the means being controlled in accordance with the mean secondaryemission current from the screen 2 whereby the signal level during the flyback intervals is rendered substantially independent of the primary current in the monoscope. During each flyback interval a pulse 17 is applied to the control grid 5 of the monoscope to cut off the beam current in the tube which results, in a tube of the type employed in the present invention in a white-level signal on the output conductor 10, the amplitude of the signal being dependent upon the primary current and hence upon the mean secondary-emission current in the tube. At the same instants as the pulses 17 are applied to the grid 5 pulses 16 are applied to the suppressor grid of the variablemu pentode valve 7, the gain of which is controlled by the mean secondary-emission current which is derived from the final anode 14 by means of the integrating circuit 11, 12 via a stage of D.C. amplification and applied to the control grid of the valve 7. The pulses 18 at the anode of valve 7 are dependent in amplitude on the secondary-emission current in the monoscope; these pulses are inverted in circuit 19 and then combined with the monoscope output to reduce the white-level signal to the black level. By a suitable choice of circuit components and appropriate adjustment of cathode resistor 8, variations in the amplitude of the white-level signal generated in the monoscope may be compensated by corresponding variations in the amplitude of the pulse output from circuit 19. The combined output signal may subsequently be combined with suitable line and frame synchronizing pulses.

Title: Improvements in the ejection or injection of electrons in magnetic induction accelerators
IPC: H05H11/00
Filed: 1948-10-11
Abstract: 682,504. Magnetic induction accelerators. AKT.- GES. BROWN BOVERI, & CIE. Oct. 11, 1948 [Oct. 11, 1947], No. 26405/48. Class 39(i) Ejection or injection of electrons in magnetic induction accelerators is obtained by forces which influence the electrons in a direction at right angles to their velocity and over not more than a quarter of the orbit, additional forces being provided for influencing the electrons in the opposite sense. Excitation coils 1, 1<SP>1</SP> produce a magnetic flux in magnet iron 8, a part 3 of this flux flowing by way of the inner poles 2, 2<SP>1</SP> to give an accelerating field, and a part 4 flowing by way of external control poles 5, 51 to cause the electrons to execute a circular movement in the vacuum tube 7. An electrode pair 9, 91 exerts deflective forces over a small portion of the orbit, whilst the electrode pair 10, 10<SP>1</SP> produces forces in the opposite direction. Coils 6, 6<SP>1</SP> produce an additional magnetic field for enlarging the electron orbit. The deflective and opposing deflective forces can be produced by special coils which only surround the control coil. One of the forces can be obtained by altering the ratio of the control field to that of the inductive field by iron saturation or phase displacement. Fig. 4 shows the effect of a deflective force F<SP>1</SP> on the electron orbit and of a counter force F<SP>2</SP> applied over the major portion of the orbit, a peak S being produced such that upon expansion of the orbit by means of coils 6, 6<SP>1</SP> electrons are ejected at that point. Other symmetrical and asymmetrical combinations are described. The forces may be given a component perpendicular to the radial direction by inclining the coils or electrodes, and in Fig. 9, the electrons 20 may be brought between the plates 21, 21<SP>1</SP> of a condenser placed outside the orbit 19, 191 and given a further deflection to remove them finally from the acceleration channel of the vacuum tube. Similar methods for injecting the electrons are also described in Figs. 10 and 11 (not shown), the latter comprising two linked coils producing the deflective force and opposed force respectively to give a parallel displacement.
