Title: Improvements in or relating to radar systems
IPC: G01S1/02
Filed: 1946-12-04
Abstract: 630,616. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Dec. 4, 1946, No. 35953. Convention date, July 31, 1941. [Class 40 (vii)] In order to measure very short ranges in a pulse radar system with a type-A cathode-ray. tube display, a very high-speed time-base synchronized with the radiated pulses is applied to the X plates of the tube and both the direct R.F. wave pulses and the R.F. echo wave pulses are applied without rectification to the Y plates so that the R.F. waveform of the pulses is visible on the screen and provides a timing calibration, the time of reception of the leading edge of the echo pulse being indicated by a change in the amplitude of the waveform displayed. Switching means are also provided for converting the system to give a conventional type-A display when measuring longer ranges. In the pulse altimeter shown in Fig. 1, the output from a transmitter 3 controlled by a pulse generator 1 is applied to the transmitting aerial 13 and a portion of the output is also applied to a detector and limiter 19, Fig. 4 (not shown), to produce a very high speed sweep voltage which is applied through amplifier 21 and switch 7 to the X plates of the cathode-ray tube 11 and the direct wave pulse received on a separate aerial 25 is applied through the R.F. amplifier 23 and switch 27 to the Y plates 29 to produce a timing trace 39, Fig. 3. At very low altitudes the echo pulse will be received before the direct pulse has terminated and the overlapping portions of the two pulses will produce a resultant waveform 41 of greater or less amplitude than the waveform 39 depending on the relative R.F. phase of the overlapping pulses, the point where the amplitude changes indicating the altitude. ' The rate of change of altitude may be determined by observing the rate of change in the amplitude of the resultant waveform 41 caused by changes in the R.F. phase of the echo pulse with changes in altitude. At greater altitudes the ganged switches 7 and 27 are operated to connect a slower speed sweep generator 5 synchronized by the pulse generator 1 to the X plates, the direct and echo pulses being applied through a superheterodyne receiver 31, 33, 35 to the Y plates to give a conventional type-A display. In a modification the fast sweep is produced by amplifying the initial portion of the slow sweep.

Title: Improvements in or relating to electronic valves
Inventor: HARTNELL-BEAVIS MICHAEL CARL
IPC: H01J25/78
Filed: 1955-12-15
Abstract: 816,333. High-frequency discharge tubes. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 12, 1956 [Dec. 15, 1955], No. 35985/55. Class 39(1). An amplifying valve comprises a perforated cylindrical sheet cathode 2, Fig. 1, one surface of which has an effective secondary emission coefficient greater than unity, an electrode 1, coaxial with and facing this surface, and an anode 3 coaxial with and facing the other surface of the cathode. Appropriate potentials, positive with respect to the cathode, are applied to the electrode 1 and the anode 3. R.F. power enters the multipactor space M along an input coaxial line formed by an extension 1a of the electrode 1 and an extension 2a of the cathode and is reflected at an end disc 4 which is so spaced that a maximum of the R.F. field occurs in the centre of the cathode. Electrons leaving the inner emissive surface of the cathode return towards this surface, under the influence of an axial magnetic field provided by solenoid windings around the anode, and either strike it producing secondary emission or pass through the cathode to be collected by the anode. The cylindrical outer wall 3a of the valve provides, in conjunction with an inner conductor 3b, a coaxial output line from the interaction space I having an end wall 8 and a voltage antinode at the centre of the cathode at the operating frequency. The space within the envelope is evacuated to a low pressure and may be continuously pumped through ports along the imput and/or output lines. In a triggered ocsillator, Fig. 4, R.F. power is initially fed through the coaxial line formed by extension 1a of the electrode 1 and an inner conductor 16 into the multipactor space M through coupling means such as the hole 17. R.F. power is developed in the interaction space I and fed out along the coaxial output line formed by outer wall 3a and extension 1a but a fraction of this power, as initially determined by the spacing of the feed gap at 12, is fed back into the space M. An end cavity 14 is coupled through an iris 15 to the interaction space I and the exact frequency of operation is locked through this coupling to that of the cavity 14 which may be made externally tunable by known means. Specification 799,140 is referred to.

Abstract: 1,048,574. Relay switching systems. STANDARD TELEPHONES & CABLES Ltd. Sept. 16, 1963 [April 2, 1963], No. 36339/63. Heading H2H. An electromagnetic relay J is operated at twice the rate of a control relay by connecting the contacts st1, st2 of the latter, the winding of relay J and a capacitor C across a D.C. supply as shown in Fig. 1. Each operation of contacts st1, st2 produces a current pulse through members J, C causing temporary operation of the relay contact i. If the control relay has only one contact, e.g. st1, the circuit is completed by two resistors, each in series with a rectifier if necessary, the resistors having a common connection to the supply and individual connections to the members J, C, respectively, Fig. 1(a) (not shown). Members J, C and a single control contact st may be series-connected across the supply, with a discharge resistor in parallel with the J, C, combination, Fig. 2 (not shown). This arrangement may be modified to make the relay operating times equal by inserting between members J, C a parallel combination of a resistor and a suitably poled rectifier, Fig. 2(a) (not shown). In Fig. 3 the contacts a, b of two relays A, B (not shown), control a relay K, operation of contact a energizing a bias winding through an adjustable resistor R3, and operation of contact b causing charge or discharge of the capacitor C through one or other of the two relay operating windings to produce temporary operation of the relay for a time dependent on its polarization.

[Class 103 (i).] A fluid-friction brake comprises radial cylinders 5 mounted in a fixed drum 1 and containing pistons 6 reciprocated by eccentrics 7 and mounted on a wheel and adapted to draw liquid from a reservoir 2 through suction disc valves 17 and to force it through exhaust valves 16 into a channel 3. The return of liquid from the channel 3 to the reservoir 2 takes place through an annular channel 32 in the slide 29 of a control valve 4. The pistons are normally out of contact with the eccentrics. The brake pedal when braking is required is adapted by means of a piston and cylinder to force liquid through passages 31, 33, 28 in the control valve 4 into the reservoir 2 and through the valves 17 into the cylinders 5 thus bringing the pistons 6 against the eccentrics and causing circulation of the liquid. Further pressure on the pedal moves the slide valve 29 against a spring 30, and restricts the passage of the fluid through the channel 32 thus producing braking. To balance the forces acting in the device the eccentrics are arranged at 180‹ to one another and diametrically opposite pistons engage different eccentrics by means of an offset beak. A ring 12 and rollers 10 with balls 11 between are arranged between the pistons and the eccentrics.
