    Abstract: L'appareil de pesee, par exemple un pese-personne, comprend un element elastique deformable, muni de jauges de contrainte formees par des resistances branchees dans un pont de Wheatstone (A). La tension de sortie du pont controle en convertisseur (20) fournissant un signal dont la frequence varie en fonction de la valeur de la pesee. Ce dernier signal est applique a un compteur (23) cooperant avec une unite de traitement (21). Cette unite est reliee par l'intermediaire d'une memoire tampon (24) a un dispositif d'affichage electronique (22). L'unite de traitement permet d'effectuer des controles de la stabilite de la pesee et egalement d'afficher directement le poids net d'une pesee effectuee avec une tare, ou encore d'obtenir l'indication directe de la difference entre deux pesees successives.

    Abstract: The rocket comprises a detonator-carrier rotor pivotingly mounted on a body (1) by means of a shaft (15) and susceptible of pivoting from an inactive position to an active position. An exhaust time delay device (26) enables to brake the rotation of the rotor and comprises a multiplier gear train (27) carried by two platens (36) and co-operating with a rock lever (28). The rotor is integral with a toothed sector (29) in mesh with the time delay device (26). The platens (36) are pivotingly mounted on bearings (14) of the shaft (13), thereby enabling an angular displacement of the time delay device (26) about said shaft to enable an adjustment of the angular meshing distance of the toothed sector (29) with the time delay device (26) and, therefore, an adjustment of the time duration of the passage from the safety position of the rotor to the cocked position. The safety distance of the mouth may thus be adjusted by a low cost and safe device.

    Abstract: This machine comprises an electric circuit divided into a first high-voltage section and a second low voltage section. The second section is supplied via a step-down transformer (T) connected to the first section. The second section comprises a rectifier (G1, G2) connected to the output of the transformer for dispensing DC power to all the functional elements of the machine. The first circuit section, the transformer and some elements of the second section of the circuit are housed in a remote casing (10) which is separate from the machine itself (1 to 4) to which it is linked by a cable (9). The foot pedal (13) for actuating the machine can be associated with the first casing with which it is made integral.

    Abstract: The rocket comprises an electric generator (2) including a magnetic core (3) which moves upon firing into a winding (4) to provide a charge pulse to the capacitor C for firing the fuse (6). To improve the resistance to shocks other than that which is generated upon firing, the displacement of the core (4) may be effected only after perforation of a metal plate (17) by means of one end (16) of a rod of which the other end (20) is to be struck by a mass (23) which moves against the action of a spring (22) upon firing.
