Abstract: 1. A process for checking the synchronous operation of two code devices via which data is transmitted from a first station to a second station and vice versa, characterised by the following process steps : A) following a start procedure, a random text is produced at the first station (STAL) and transmitted in coded form ; to the second station (STA2) ; B) the coded random text is decoded and stored in the region of the first station (STA1) ; C) In the second station (STA2) the random text is decoded and the random text as decoded at the second station (STA2) is subsequently transmitted in coded form back to the first station (STA1) ; D) the received coded random text is decoded in the first station (STA1) and compared with the random text stored in the region of the first station (STA1) ; and E) in the event of inequality of the received random text and the random text stored in the region of the first station (STA1), an alarm signal is emitted.

Abstract: Disclosed is a restore circuit for restoring an integrated semiconductor storage array having storage cells consisting of bipolar transistors. The restore circuit includes a reference voltage generator, an impedance converter, and switches to connect the reference voltage generator and the impedance converter to the storage array. The reference voltage generating circuit includes a current source and at least one reference storage cell identical in construction to the storage cells of the array. The reference voltage generating circuit provides a reference voltage to the impedance converter which supplies a second reference voltage to the array at a greatly reduced impedance. The equivalent circuit of the storage cells is that of a capacitor in parallel with a diode. Thus, the impedance converter provides an initial surge of capacitive current which restores the cells, followed by a standby current which is a function of the diode characteristics of the cell equivalent circuit.

Abstract: Conventional time-delay-triggered Trapatt oscillators, for example in coaxial line, include a multi-element low-pass filter in which the positions of the elements are adjustable and in which the filter element nearest the Trapatt diode also constitutes a trigger element for reflecting energy back to the diode so as to trigger a further cycle of oscillation. However, the other filter elements may also have a similar effect. Consequently, the operation of the oscillator is critically dependent on the positions of the filter elements: adjustment for optimum operation is lengthy and difficult, and results are not reproducible. To mitigate these disadvantages, the invention provides a Trapatt oscillator which does not require a low-pass filter: there is a single trigger element (S) and a progressive increase in impedance from the Trapatt diode (T) to the trigger element (S).

Lors de l'emboitement, le panier tourne automatiquement vers une position superieure predeterminee, ce qui fait basculer vers le haut la partie avant du panier de maniere telle qu'il puisse entrer a l'interieur de la partie arriere du chariot precedent. Lorsque les crans de verrouillage sont degages des ouvertures, le panier tourne automatiquement vers le haut par la force des ressorts de verrouillage (214) accouplant le panier au chassis. Une tige de forme generale en U (202) s'etend horizontalement le long des paniers avant et lateraux et chacune de ses extremites libres est attachee aux projections de verrouillage. Un mecanisme arme a ressort pousse la tige tenu vers une position de repos avant. L'impact de la tige avec le chariot precedent pendant l'emboitement provoque sa deflexion vers l'arriere, degageant ainsi les projections de verrouillage hors des bords de verrouillage pour que le panier puisse etre tourne vers le haut vers la position superieure predeterminee de maniere a permettre l'emboitement.

Abstract: Antifreeze pump for introducing liquid antifreezes into compressed-air systems, particularly into compressed-air braking systems of motor vehicles. In a pump housing (1) a first chamber (2) is provided through which pressure medium flows and which is connected via two connections to a pressure medium source, on the one hand, and, on the other hand, to a load. The chamber (2), through which the pressure medium flows, can be connected via a valve (18, 19) to a second chamber (8) for accommodating antifreeze. In the pump housing, a piston (4) operating the valve is provided. The chamber for accommodating antifreeze can be connected to an antifreeze storage container via holes (9, 10, 12). To avoid the need for removing the drive for the pump piston during summer operation of the vehicle, a shut-off valve (11) is arranged between the antifreeze storage container (13) and the chamber (8) receiving the antifreeze, so that, although the pump piston is still operated during summer operation, no antifreeze is delivered. <IMAGE>

Filed: 1981-02-03
Abstract: L'invention concerne une nouvelle configuration de bobines électromagnétiques pour obtenir des images à usage médical de l'intérieur du corps humain. La méthode d'obtention des images utilise la Résonance Magnétique Nucléaire (RMN) de noyaux contenus dans le corps humain placé dans le champ magnétique ?0 d'un électro-aimant. Cette méthode est intéressante, en particulier parce qu'elle est inoffensive, mais sa sensibilité est faible et des temps de pose très longs sont habituellement nécessaires. Afin d'améliorer la sensibilité de la mesure l'invention concerne un appareil où le patient (2) est placé transversalement et non plus longitudinalement par rapport à l'axe de révolution (4) de l'électro-aimant (1). La bobine de RMN (3) (dont l'axe H1 doit être perpendiculaire à ?0) peut alors être constituée d'une seule spire circulaire placée autour du corps du patient et non plus de deux ensembles de spire disposés en "selle de cheval" de part et d'autre du patient. Cette configuration est optimale du point de vue de la sensibilité. Elle doit permettre de réduire les temps de pose d'un facteur supérieur à 2 par rapport aux systèmes classiques à bobine de RMN en "selle de cheval".
