Abstract: In a process and device for the angular discrimination of targets by airborne radar, the angular position of a point on the ground is ascertained as a function of the Doppler frequency of an echo signal relating to the point under consideration, as determined by passband filtering the echo signals.The Doppler frequencies are selected by a bank of filters and an angular determination is made by analyzing signals including a signal representing the position in the bank of that filter selecting the Doppler frequency of the echo signal, and a reference frequency subject to closed loop control and representing the true Doppler frequency of the ground. Means are provided for maintaining data relating to the position and the range of the target constant during the process of analysis.

Abstract: According to the invention, the circuit comprises at least one two-port network of the "M-derived" section type and connected as an all-pass filter with a phase law which is a linear function of frequency. The two-port network is made in monolithic technology on gallium arsenide and the plane of its structure includes at least one elementary section, which, between an inlet and an outlet which are situated at a distance apart, is constituted by a spiral connected in parallel with a capacitor of metal-insulator-metal structure, with the mid point of the spiral being connected via another capacitor of metal-insulator metal structure to a ground plane. It is applicable to making transmission lines which are programamble in length.

Abstract: The present invention relates to a device (1) for positioning a mock-up (2). The device comprises supports (3, 4) suitable for holding the mock-up in a variable position which is controllable in attitude and/or altitude relative to an illumination axis (I-I'). The mock-up is held by two pairs of top wires (6) and by two pairs of bottom wires (7). These four pairs of wires are mounted at their opposite ends on tensioning means (8) fixed to the opposite ends of the supports (3, 4) and intended to adjust the tensions and the lengths of the wires as a function of a desired attitude and/or a desired altitude for the mock-up. The device also includes control means (9) for controlling the angular positions of the supports (3, 4), and cameras connected to processor means for measuring the real position and attitude of the mock-up.

Abstract: A disk (110) carries containers (such as 120) each containing a stack of cards capable of being extracted one-by-one via an orifice (126) when a wheel (151) is moved to an extraction position (151A). A first conveyor (140A) then conveys the extracted card to a programming unit (1) which is capable of being moved to a position enabling a card to be inserted therein without friction, and thereafter lowers a connector (6) onto the card. After the card has been validated and inspected, it is conveyed to a user along the first conveyor (140A) and then along a second conveyor (140B) terminating at a delivery slot (105). An invalid card may be directly rejected into a reject box (180) placed beneath the programming unit (1).

Abstract: A coherent pulse radar is activated successively according to at least two pulse repetition frequencies. These frequencies are of values such that (a) the received signal is ambiguous both with regard to distance and with regard to velocity, and (b) their ratio is reducible to the quotient of two integers which are preferably adjacent and have no common factors. For the frequency analysis, a number of samples is taken which depends upon the pulse repetition frequency, the numbers of samples associated with the two pulse repetition frequencies being, in relation to one another, in the ratio of the two integers. The distance/velocity resolution cell is then invariant with respect to the pulse repetition frequency; this permits removal of the ambiguity concerning mean information items appertaining to a long integration time.

Abstract: An electrical power supply circuit, in particular for a pulse radar wave generator, includes a chopper regulation circuit and a transformer which is fed from a low voltage source. The primary winding of the transformer of the circuit has a plurality of primary windings wound on a common transformer core. Each of the primary windings is connected to the low voltage source via an electronic power switch controlled by a voltage regulation signal at the repetition frequency of the radar pulses or at a multiple of the frequency. The transformer secondary includes a plurality of secondary circuits with their outputs connected in series between the very high voltage output terminals of the power supply circuit as a whole.

Abstract: Apparatus for processing card tickets includes a printing and/or encoding module (1), having means for driving a ticket along a path internal to the module (1) in order to pass it through a ticket print station and, where appropriate, a ticket encoding station (160), and then to a ticket outlet between two wheels (150, 193). A second module (2) is provided, similar to the first, and coupling means (3) are provided between the respective outlets from the two modules (1, 2) and an outlet receptacle (370) in order to take tickets from one or other or both of the modules (1,2) and stack them in the receptacle (370).

The stepper motor (185) has at least five phases, and the same clock (21) is used to control the stepper motor (185), the transfer of data from said unit (22), and the data modulator (23) in order to establish control transitions which are applied to the magnetic head.

Abstract: A box (100) includes one or more housings (130) each of which is capable of receiving a memory module (MM). The memory modules have longitudinally extending side grooves and the housings are provided with corresponding module-guiding tongues (111) and 112). The back of each module includes orifices for engaging centering pegs (PC11 and PC12) to ensure that a male connector portion (C1) on the memory module is properly engaged with a female connector portion (C2) which is cushion-mounted at the back of each housing. A switch (IC10) detects when a module is fully inserted and the connectors are properly engaged. Complete insertion of a memory module is ensured by means of a toothed sector (121) engaging a rack segment (SC21) located at the front of one of the grooves. The toothed sector (121) is actuated by a lever (125) which closes across the front of the housing (130) and is locked in place by means of a screw (128) having a knurled knob (127).

Abstract: A reader for reading magneto-optical characters, with the options of printing them or storing them.A track is provided for driving a check from an inlet plate (T1) over various portions of path (T2, T3 and T4). Wheels (G1 and G2) are provided beneath the path, and may be motor driven. Above said wheels there are heads (TM1 and TM2) respectively for premagnetizating and reading CMC7 characters. Each head is mounted on one arm of a corresponding bell crank (L1, L2) which cranks are pivoted to a frame at their corners (L10 and L20). The other arm (L12 and L22) of said bell cranks are resiliently urged by springs (L15 and L25) mounted on an actuator rod (AC) which is itself driven by an electromagnet (EM2). It has turned out that such an assembly ensures effective transducer operation of the heads (TM1 and TM2) for reading CMC7 characters.

Abstract: A very high voltage stabilized power supply device for a pulse radar system, in particular an airborn radar, which comprises a primary winding connected in a series with an electronic power commutation switch actuated at the recurrence frequency of the pulses produced by the radar, or at a multiple frequency of the recurrence frequency, to the terminals of a rectified and filtered voltage supply source. The primary is wound around an inductive element on which are wound a plurality of secondary windings with a primary-secondary winding transformation ratio equal to unity. Each secondary winding is connected in series to a diode with a filter capacitor in parallel. The outputs of the secondary circuits are connected in series so that their voltages accumulate at the output of the power supply unit. Several modules of this type may be used, with their commutating elements actuated on a staggered basis.

Abstract: A device for cutting a strip of paper or similar material, i.e. material in a flexible sheet which can be cut or torn easily, said strip having preestablished transverse lines of weakness. The strip is tensioned and then contacted with a blunt edged blade to tear the strip at the line of weakness.

Abstract: A card ticket, e.g. for travel, is taken from a stack of blanks (101) which it leaves via two wheels (111, 112) travelling along an axis (113) which does not coincide with the common tangent to two touching wheels (135, 175) which receive the ticket taken from the stack. Thus, once the ticket has completely left the stack unit from which it is taken, it may be reversed partially or totally back out between the receiving wheels (135, 175) without re-engaging the stack unit. The same arrangement can be used at the other end of the internal path to receive a ticket at wheels (163, 203). These wheels can both output a ticket towards a user (arrow F3) and receive a ticket from a user for inspection (arrow F4). Apparatus of this nature can thus create new tickets, inspect unused tickets and return them, and inspect used tickets, cancel them and retain them (arrow F5).

Abstract: The printer is for printing on a narrow print-receiving medium such as a ticket (T) which passes lengthwise through the printer. The printer includes an anvil or platen which is at least partially constituted by a cylindrical roller (150) capable of rotating about its own axis (322) in such a manner that its cylindrical surface accompanies the movement of the narrow medium substantially without slipping. A dot-matrix print head is movable in translation transversely to the motion of the medium so as to print thereon against a generator line of the roller. The improvement lies in the printer further including a unitary guide assembly (301, 302, 307, 313) for guiding both rotation of the roller and translation of the print head.

Abstract: A rotatable tray for supporting at least one package together with at least one nozzle for projecting a jet of liquid along an axis which is substantially at 45.degree. to the axis of rotation of the tray.

Abstract: A ticket (1) is driven by an endless belt (10) which is serrated on one surface. The belt engages only a fraction of the width of the ticket. At a print station which includes a dot-matrix print head (145, 146) the ticket passes over a smooth platen roller (150) which includes a portion (152) of reduced diameter in which the belt is received so that its smooth surface comes level with the rest of the cylindrical surface of the platen roller. The print head moves along a generator line of the platen roller, and the roller itself or the drive belt provide the required backing for printing on the ticket.
