Patent GB-611725-A (GB)
Title: Apparatus for determining the distance of objects by reflection of frequency-modulated oscillatory energy
IPC: G01S1/02
Filed: 1945-08-29
Abstract: 611,725. Radiolocation. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Aug. 29, 1945, No. 22300. Convention date, Aug. 5, 1944. [Class 40 (vii)] In a pulse-transmission system, the transmitter oscillations are frequency-modulated and distance is measured by combining reflected pulses with transmitter energy to produce impulses modulated in amplitude at the difference-frequency. When the transmitted pulses are longer than the maximum reflection period so that the transmitted and reflected pulses overlap in time, the difference frequency can be directly obtained by combining the overlapping portions. When the transmitted pulses are relatively short, energy from the transmitter oscillator is combined with the reflected pulses producing an impulse train, the envelope of which gives the difference frequency. In the system shown in Fig. 1, a continuous-wave oscillator 0, frequency-modulated by a saw-tooth, sinusoidal or similar wave generator W feeds an amplifier T which is keyed by a pulse generator J and the output is radiated. Reflected pulse energy is received in a receiver M where it is mixed with some of the energy direct from the oscillator O. The beat frequency output of the receiver M is fed through a gating device U and filter F to a frequency-measuring circuit K. The device U is gated by the output of the pulse generator J which passes through a delay network P. With a saw-tooth modulation, the slope of the modulation frequency may be variable and adjusted to give a constant difference frequency so that the setting of the slope adjustment will give a measure of the distance. The duration of a modulation cycle may be equal to the duration of a transmitted pulse, or the modulation frequency may be equal to the pulse recurrence frequency or to a sub-multiple thereof. In the modification of Fig. 9, the modulation frequency voltage fs is partly sloping and partly constant and in this arrangement relative speed is ascertained by the application of the Doppler principle during the constant periods and distance during the sloping periods. The shaded portions e4 represent the transmitted pulses. A super-regenerative receiver may be employed in which the frequency of the quench voltage coincides with the pulse-recurrence frequency and the phase of the quench voltage is adjustable in accordance with the reflection period.

Abstract: 830,083. Television pick-up tubes. GRUNDIG, M. July 23, 1956 [July 23, 1955], No. 22715/56. Class 39(1). [Also in Groups XL(b) and XL(c)] In television apparatus incorporating a camera tube of the vidicon type means are provided for controlling the potential of the target electrode in accordance with the signal current in order that a desired parameter, e.g. the peak or mean level, of the signal may remain more nearly constant in the presence of wide variations in image luminosity. The arrangement is illustrated in Fig. 2 where the output from the video amplifier 3 is rectified at 9 to produce a control potential which is applied via an amplifier 11 to the lower end of resistor combination, 12, 13 forming the load of the target of the camera tube 1. A supplementary control may be effected by a potential applied from resistor 12 via a circuit 5 to operate a motor 6 controlling an adjustable diaphragm 7 in the light path to the camera tube. The timeconstant of the rectifier circuit is made adjustable, either continuously or in steps selected by a switch 10, so that peak, mean or intermediate values of the signals determine the output. Peak rectification is employed where it is desired to provide maximum signal contrast for bright regions of an image, and mean-level rectification where it is desired to provide maximum signal contrast for darker regions. The time-constant of the control circuit is made at least ten times the frame scanning period. Reference is made to the use of peak-white limiter in the video output. As an alternative, the supplementary control of the diaphragm may be effected from the D.C. component of the signal current. Fig. 3 (not shown) illustrates a circuit for applying the control potential from the rectifier to the target electrode.

Abstract: 799,221. Spring suspensions; preventing overturning; arrangement of wheels and axles. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 18, 1954 [Aug. 18, 1953], No. 22795/53. Class 108(2) In a tractor, at least the driving wheels are controllably tiltable about fore and axes each located within a distance from the media plane of the wheel tyre of one and a half times the width of the tyre. As shown in Figs. 1 and 2, a horizontal king-pin 13 is interposed between the outer end of a driven axle casing 14 and a wheel carrier 15, a constant-velocity universal joint 18 centred on the king-pin axis connecting a driving shaft 17 and a stub axle for the road wheel 16. Each carrier 15 is connected through an arm 19 and a link 21, with a manually operated screw and nut device 22, 23, 24 by which the wheels are tilted about the king-pin axis. In another arrangement, Fig. 3, a horizontal king-pin 25 is located above the driving shaft axis, the wheels being tiltable as above by links 33 disposed below the axle casing. In another arrangement, Figs. 4 and 5 (not shown), reduction gearing is incorporated in the wheel carrier, a telescopically universally jointed driving shaft being located externally of the axle casing and the horizontal king- pin being interposed between the axle casing and the wheel carrier at the level of the wheel axis. In the arrangement according to Fig. 6 (not shown), the horizontal king-pin of the Fig. 4 arrangement is located above the wheel axis on the axis of the outer universal joint of the driving shaft, the tilting of the wheel being controlled by a link as on the Fig. 3 arrangement. In all arrangements, the control means for tilting the wheels may be associated with a bubble-tube indicator, Fig. 7 (not shown). In an arrangement according to Fig. 8 (not shown), the tilting is controlled automatically from a hydraulic power system provided on the tractor. According to Fig. 9, each wheel 63 is movable vertically and is tilted by means of suspension links 65, 66, the upper links 65 of which are connected to opposite ends of a torsion bar 71 which is actuated by a hydraulic cylinder 75 to displace the wheels bodily in opposite directions. The invention is applicable to tractors having separately driven wheels, e.g. hydraulic or electric drives with a separate motor associated with each wheel. Also, the driver's seat may be adapted to tilt in correspondence with tilting of the wheels.

[Class 38 (iii).] Apparatus for walking exercise comprises a motor driven track 5, Fig. 1, and a control means for varying the rate of the track in accordance with the demand of the body upon it. This variation may be effected either by photoelectric control with beams of light projected across the track or, as shown, by the variation in capacity between the body 27 and an electrode 20. The track 5, Fig. 3, may be driven by a D.C. motor 9, the field of which is supplied from a rectifier 29, while the armature is supplied from a thyratron 35, the output from which is varied by varying the phase relation between its anode and grid potentials. The grid 40 is supplied from a transformer 42 fed from a bridge having two fixed resistance arms 43, a variable resistance arm 44 and a variable impedance arm containing saturation reactors 45 connected to the output of amplifiers 47. The amplifiers 47 receive energy from a rectifier 55 supplied with energy from a pick-up coil 53 from a high frequency oscillator 54 having associated with it a coil 65 connected to the electrode 20 and to the grid of the oscillator 54 through a condenser 66 and tuned to resonate at a frequency slightly below that to which the oscillator is tuned by the condenser 58. The capacity 58 may be varied to vary the distance between the body 27 and bookrest 25 at which the apparatus operates. A time delay device consisting of a variable resistance and shunt capacity 51 is inserted between the rectifier 52 and amplifier 47.
