Abstract: 1309536 Doppler radar BENDIX CORP 15 July 1971 [23 Sept 1970] 33167/71 Heading H4D  A vehicle mounted Doppler radar includes an antenna transmitting and receiving energy from a rearward selected angular field of view, means for modulating said transmitter to radiate sequentially at two discrete frequencies, means for mixing the received and transmitted energy to produce a signal having first and second envelopes defining first and second Doppler signals, means for yielding a signal derived from the phase relationship thereof whose polarity and amplitude represent sense of relative velocity and range respectively, and a warning device responsive to said signal. In a vehicle anticollision system for use when changing lanes, two antennµ are arranged on either side of the vehicle. The antennµ either (i) have separate receiver systems, (ii) time-share a single receiver system or (iii) are actuated selectively by the turn indicator of the vehicle. The receiver has a Gunn diode oscillator 17 modulated by a square wave to transmit alternately at two frequencies. The echo signals are mixed and fed to amplifiers 19, 22 gated at the modulation frequency to provide the two Doppler frequency signals fd 1 , fd 2 . These signals are filtered &c. and passed to phase comparator 25 which produces a signal whose polarity denotes a closing or receding target and whose amplitude represents range. Closing signals of less than a predetermined range are fed to warning actuator 26 which provides a visible and/or audible signal. The warning signal may be used to illuminate the circumference of the rear view mirror. In addition while reversing a separate rearwardly pointing aerial provides a signal to an audible warning which is actuated by echoes above a preselected threshold level.

Title: Improvements in or relating to circuit arrangements for supplying an impedance with current pulses
IPC: H02M3/04
Filed: 1959-09-30
Abstract: 929,786. Transistor switching circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Sept. 30, 1959 [Oct. 3, 1958], No. 33184/59. Class 40 (6). In a transistor switching circuit in which pulses of current are fed through an impedance 3 connected in the emitter circuit of a transistor 1 in accordance with switching pulses applied to the base electrode of the transistor, the magnitude of the current flowing during these pulses is maintained constant, despite variations in the value of the impedance 3 by feeding back voltage variations appearing at the emitter of the transistor through a unitygain amplifier, such as emitterfollower 11, to one end of a resistor 22 whose other end is connected to the collector of the transistor, thereby to maintain the voltage across the resistor during current pulses, and hence the current through the resistor and through the impedance 3, constant. The impedance 3 comprises a plurality of seriesconnected cores of a magnetic store; the voltage developed upon the application of a pulse consequently depends upon the states to which the cores have been set. In the circuit shown a resistor 21 is provided to allow current to flow initially through the transistor on the application of a switching pulse from the transformer 9. Fig. 6 shows a modified form of circuit in which two cascaded emitter-follower stages are interposed between the diode 13 and the blocking capacitor 14. In this arrangement the initial flow of current is provided from a capacitor 32 through the diode 18; when transistor 11 commences conducting, however, the diode is reversely biased and the capacitor is able to recharge. The diode 13 prevents the application of negative pulses, developed across the impedance 3, to the base of the transistor 11 or 16, so that the reverse collector-base voltage is not exceeded. It is stated that the feed-back may be effected through a cathode follower constituted by a triode operable with a low value of anode voltage, thus reducing the current drain imposed by the amplifier upon the impedance 3 and removing the need for a diode 13. Specifications 765,326 and 806,559 are referred to.

Title: Improvements in or relating to colour television receivers
Inventor: TOWNSEND GEORGE BORIS
IPC: H04N9/20
Filed: 1959-09-30
Abstract: 906,913. Colour television. GENERAL ELECTRIC CO. Ltd. Sept. 28, 1960 [Sept. 30, 1959], No. 33186/59. Drawings to Specification. Class 40 (3). In a colour television receiver, a switch control conveniently accessible to a viewer permits the bias applied to the image reproducer to be changed in such manner as to make a small change in the colour balance of the reproduced image, without seriously affecting the grey-scale tracking, to allow for the subjective effect of such factors as the colour of ambient illumination. The invention is described as applied to a receiver for the N.T.S.C. type of signal which utilizes a cathode-ray tube having three electron guns of the tetrode type. In one arrangement (illustrated by a drawing, not shown), a ganged pair of switches permits the simultaneous change of the bias on the control and screen grids of the " blue " gun. The amount of blue light is thereby slightly reduced and a slight yellow tint imparted to the image. The amount of the change is governed by pre-set adjustable resistors. In other arrangements (not described in detail) the change may be applied to colours other than yellow.

Title: Improvements in or relating to bandages
IPC: A61F13/00
Filed: 1953-12-02
Abstract: Elastic bandages are woven with a proportion of the warp threads consisting of sinuous synthetic filaments.  The crimping of the threads is produced during extrusion and the straightening under tension gives the desired elasticity.  The projecting loops of the threads also tend to interengage when two surfaces are placed together, as in winding on a limb, and this tends to minimize slipping.  The weft threads may also be partially of similar filaments and a proportion are of cotton to increase absorption of moisture.
