Abstract: In cathode-ray tubes utilising screens with a luminescent layer made up of two kinds of phosphors having different spectra, one having virtually no remanence (1), and the other being of remanent kind (2), with switching of the voltage between two values, low and high, the second phosphor only being excited at the high value, due to the presence of a barrier B, in order to prevent the unwanted flash of different colour, produced by the non-remanent phosphor at the instant of appearance of the remanent trace, the invention provides for the addition to the aforementioned two constituents, of a third non-remanent phosphor (3) equipped with a barrier B and having a spectrum such that the superimposition of the flash which it yields at high voltage, and that yielded by the phosphor (1), produces the colour corresponding to the phosphor (2). Application to radars using real and synthetic video signals.

Abstract: The present invention relates to a radar system haing a high range resolution. Said radar system emits series of n pulses whose carrier frequencies are distributed within a band B and whose time positions are associated with the frequency in accordance with a linear reelationship. The echoes received in return are demodulated with the corresponding waves which gave rise to them, and supplied to a filter bank which produces at different outputs, different signals which correspond to separate objects or parts of objects.

Abstract: A processing device for stretching video signals in a pulse radar system between the output of the receiver of large pass bandwidth and exploiting means such as an oscilloscope. A delay line connected to the output of the receiver provides a plurality of output signals to an non-linear circuit which transmits, to said exploiting means, only the signal having the greatest amplitude and blocks the other signal for preserving the signal to noise ratio.

Abstract: A high-precision digital-to-analog converter, manufactured by the technique of monolithic integrated circuits, uses integrated resistors formed by ion implantation. The resistors are arranged in a series of ladder networks, the steps of each ladder corresponding to predetermined binary digits of a logical information. Fuses interconnect different steps of different ladders; they can be melted by passing an overload current through them. Their elimination in suitable locations facilitates an adjustment of the converter.

Abstract: A plurality of public-transport surface vehicles such as buses, each identified by an individual number, are equipped with transmitters for sending out that identification number together with heading and positional data conveying information on direction of travel and momentary distance from a point of departure; the transmitted information may also indicate the state of occupancy of the vehicle. This information is received at transit points along the route, each transit point including circuits for determining from the directional and distance data the distance of an approaching vehicle from that point. If the transit point is a passenger station, the shortest vehiclular distance or distances are registered with the accompanying identification and occupancy data in one or more stores for display to waiting passengers. The directional and distance data can also be intercepted by a traffic-control post to detect the approach of vehicles at an intersection as an aid in the operation of traffic lights. The data-evaluating equipment at any such transit point includes a comparator determining whether a newly arriving signal is from a vehicle whose data have already been registered in a store thereof, i.e. whether the transmitting vehicle is among those closest to that point at the instant of reception.

Abstract: Vehicles traveling along a predetermined route are equipped with mobile receivers picking up traffic information from a radiating transmission line extending along the route, this information being modulated upon a first carrier F1 for vehicles traveling in one direction and upon a second carrier F2 for vehicles traveling in the opposite direction. Two ancillary short-range transmission stations, located at opposite ends of the line, radiate amplitude-modulated carrier waves directly to vehicles in the vicinity thereof whose receivers are tuned to either of the two carriers F1, F2. The first ancillary station emits the two carriers both modulated with a low-frequency signal f1 whereas the second ancillary station emits the same carriers modulated with a different low-frequency signal f2. A discriminating circuit aboard each vehicle, upon the reception of an amplitudemodulated carrier, tunes the receiver thereof either to the carrier F1 in response to a detected signal f1 or to the carrier F2 in response to a detected signal f2.

Abstract: A display instrument using optical collimation for projecting data into the line of sight of an observer, comprising an optical lens which projects images of luminous objects focused at infinity onto a transparent combining glass. The luminous objects corresponding to data be displayed are positioned in the focal zone of the lens. The images are reflected by the glass into the observer''s line of sight. A reflectively deflective prism placed in the optical path between the optical zone and the luminous objects, enables the use of an optical lens of greater diameter whereby the operational characteristics of the equipment are improved.
