Abstract: This target indicator makes it possible to increase the accuracy and efficiency of guidance of homing missiles towards a target. For indicating ground targets, it comprises an ovoid casing (15) equipped with a rip cord (4), with a magnet (1) and with a coil (11) for detecting a variation in flux at the time of an impact on a magnetic surface. Arranged inside the casing are a battery (6), an electronic control and transmission circuit (5) and a barrel (2) of pulse generators (13) connected to one another by means of pyrotechnic delay devices (12). The barrel opens out onto a single nozzle (3) inclined relative to the axis (Z) of the casing. After impact on the ground, the electronic circuit (5) commands the ignition of the first pulse generator. The other pulse generators cause jumps until fastened on a magnetic surface by means of the magnet (1). After the detection of the flux variation, electronic circuit (5) commands the ignition of the rip cord (4) for the purpose of ejecting the casing (15) and the barrel of pulse generators (13) and triggers an ultrahigh frequency or infrared transmitter, depending on the particular homing missile to be homed in.

Abstract: The optical and electronic equipment normally carried by an aircraft pilot's helmet is carried by a support element which is placed at a distance from the helmet and accordingly relieves the load on the pilot's head. The support element is maintained in a predetermined position location with respect to the helmet by means of a detection assembly, a computer for determining errors in positioning, a control circuit which generates signals corresponding to these errors, and a set of jacks controlled by the error signals for modifying the position of the support element with respect to the aircraft structure and cancelling the positioning errors.

Abstract: 1,262,386. Moriopulse radar. THOMSON CSF. 9 Oct., 1969 [15 Oct., 1968], No. 49719/69. Heading H4D. A monopulse radar receiver comprises an MTI system fed from a phase detector having a reference input from a wave generator and a sum echo signal input wherein the sum signal is phase modified by an amount proportional to the angular displacement of the target and the radar boresight. In an airborne MTI this reduces the clutter bandwidth enabling a clutter rejection filter of smaller bandwidth to be used, thus lessening the adverse effects of the filter on target returns when a low repetition frequency is used to give a large unambiguous range. The phase is modified to make the phase between successive echoes of a target equal to that between successive echoes of a target situated on the boresight. This difference in phase is: #V c sin G cos S dGdt, for an aircraft in substantially level flight where V c is the aircraft velocity; S, G are the elevation and azimuth bearings of the boresight; dG is the azimuth angular displacement of the target from the boresight. In one embodiment, Fig. 3, the phase modification is introduced directly into the sum channel by a varactor-type variable phase shifter P which produces a phase shift corresponding to the product of JV c sin G cos Sdt and dG which is derived from a Hall effect multiplier M 2 , the integral being taken over four successive transmitter pulses and being reset by pulses from a divide-byfour clock H. dG is produced by phase comparison of #+f# and #-f#, where # and # are the sum and difference signals. The modified sum signal passes to an arrangement comprising a phase detector D 2 having an echo input carrying the modified sum signal and a reference input connected to a wave generator CO, synchronized by the sum signal delayed by a pulse length. The output of the phase detector passes to a conventional anti-clutter device AC comprising cascade connected delay lines before passing to the MTI display through a switch controlled by clock H. In a second embodiment (Fig. 4, not shown) the final MTI arrangement is identical but the phase modification is produced in an adder having two inputs, one being the sum signal delayed by #/2 and the other being the output of a multiplier having inputs #V c sin G cos S dt, derived as before and the difference signal.

Abstract: The invention provides a connector for flat connections adapted for connecting electrically together printed circuit tracks or printed circuit tracks to a flat cable or two flat cables together. The connector includes a sleeve made from a shape memory material in which the conducting elements intended to be in electric contact are superimposed. The sleeve is adapted for applying transverse forces under the effect of a predetermined temperature so that electric continuity may be provided between these elements.
