Abstract: Carried weapon system with a high orientation mobility in elevation and bearing.The elevation mobility is ensured by eliminating the turret and the provision of a shaft in the vehicle superstructure in accordance with its longitudinal axis and the fixing of the weapon to its cradle in said shaft which is open towards the top and front and beneath the weapon towards the bottom. The mobility in bearing is ensured by the self-rotation of the vehicle which displaces the weapon.Such movable turretless weapon system is able to fire at land, maritime and air targets.

Abstract: An electromagnetic detector designed to monitor road traffic, responsive to a modification of an electromagnetic field produced by the presence of a metallic mass in the vicinity thereof, comprises a metal base on which are disposed a transmitting coil creating a field and a receiving coil whose axis deviates from the perpendicular to the base. The receiving coil detects a measuring field created by the currents induced in the base by the transmitted field. The processed signal is the resultant of the signal produced by the presence of a metallic mass in the transmitted field and by the signal due to the measuring field.

Abstract: A radio receiver, especially one installed in a road vehicle, has a first section for picking up special message signals such as road-traffic information and a second section for picking up a normal radio program. A relay energizable by the special signals, normally connected to the first receiver section, automatically switches a loudspeaker from the second receiver section to the first one whenever such signals begin to arrive. A circuit breaker in series with the relay can be manually controlled by a pushbutton, through the intermediary of a bistable storage circuit, to deactivate the relay for shifting back to audible reproduction of the normal program at the will of the user even while the special message signals continue to arrive; another actuation of the pushbutton in the presence of these signals restores the original condition.

Abstract: A distress-signal generator aboard a vehicle includes a transmitter with a self-locking relay for energizing a high-frequency oscillator from a local battery in response to one or more trigger signals from respective detectors, specifically an impact detector and a deformation detector. The impact detector comprises two coacting members, one of them fixed to the vehicle body and the other freely movable with reference thereto, the elastically suspended mobile member being generally spool-shaped and having its waist received in an oblong opening of the plate-shaped fixed member. With the major axis of the oblong extending in the direction of vehicle motion, contact between the two members occurs in response to relatively small transverse and vertical accelerations but only with relatively large longitudinal acceleration; relative torsion is detected by a horizontal pin on the mobile member bracketed by two stops on the fixed member normally spaced therefrom.

Abstract: A multiplicity of launching tubes for nonguided projectiles, clustered about a central axis, are divided into several groups of 2n tubes each, the muzzles of each group of tubes being trained in directions diverging from one another in at least one dimension at a small angle designed to spread the projectiles of each group over a predetermined segment of an area centered on the main axis. The tubes of each group are subdivided into pairs whose muzzles are distributed symmetrically about the main axis and which may be fired simultaneously to provide a balanced recoil. A computer determines from the output of a tracking radar the location of a region of uncertainty, centered on the calculated position of a target to be destroyed, and selects the group or groups whose segments cover that region whereupon the tubes of the selected group or groups are fired simultaneously or in rapid succession. The entire array may undergo a sweep motion in one dimension (e.g.

Abstract: A traffic-surveillance system comprises a radar equipment coupled to a transmitter/receiver antenna. This antenna is formed by a transmission line including an elongate hollow conductor with leakage losses, such as a slotted coaxial cable or waveguide, producing along its length an electric radiating field. Any metallic mass, such as a vehicle, located within that field reflects part of the radiated energy which is then picked up by the line. Part of the reflected energy is absorbed in the characteristic impedance of the line while the remainder is conveyed to the radar equipment where it is processed to yield the required information concerning the vehicle.
