Abstract: Un élément capteur (1) pour capteurs de courant limite de détermination de la valeur de lambda de mélanges de gaz, notamment des gaz d'échappement de moteurs à combustion interne, comprend une cellule d'électrolyte solide (5) formée d'une paire d'électrodes (3 et 4) agencées sur un électrolyte solide de support (2). L'électrode interne (3) est exposée à un gaz de mesure amené par un canal de diffusion (6). Les électrodes (3 et 4) ont des pistes conductives qui peuvent recevoir une tension. Cet élément capteur permet de réduire sensiblement le temps de réaction avec une longueur prédéterminée du canal de diffusion (6). A cet effet, une cellule de pompage supplémentaire (9), illustrée dans la Fig. 5, permet d'obtenir un temps de réaction au moins quatre fois moins long que celui d'éléments capteurs dépourvus de cellule de pompage supplémentaire. On peut en outre doubler la plage des signaux par renversement du signe, sans augmenter le courant auquel les électrodes (3 et 4) du système sont exposées.

Abstract: In a motor vehicle gearbox the selector rods (30-33) carrying the forks which actuate the gear coupling devices are disposed with their axes (30a-33a) at the same distance from the axis (17) of the gearbox shaft with which the coupling devices are associated. When one of the rods is moved away from its neutral position the other rods are locked in the neutral position by locking means (18) including a first series of locking dowels (34) slidable in separate substantially parallel seats (35) formed in the gearbox casing, and cooperating with respective notches (30b-33b) provided on the selector rods. The said seats (35) open into a common cylindrical cavity (36), extending transversely thereto, in which there is provided a train of locking pins (37) resiliently thrust against one another. When a selector rod is actuated the associated locking dowel (34) projects into the said common cavity (36) causing a displacement of the train of auxiliary locking pins (37) such that these latter obstruct the exits from the seats (35) of the locking dowels (34) associated with the other selector rods.

Abstract: A printing apparatus has an array of cartridges (40,41,42) for printing a web (2) of e.g. paper passing through the array, and one or more units (48,49) containing printing medium. The cartridges (40,41,42) each are capable of transferring the printing medium from the units(s) (48,49) to the web (2). The unit(s) (48,49) and the cartridges (40,41,42) of the array are relatively movable, to allow the unit(s) (48,49) to interact successively with at least two of the cartridges (40,41,42). In this way it is possible to change printing from one cartridge (40,41,42) to another, allowing changes to be made to what is printed, without halting the movement of web (2) significantly. The present invention also proposes that the cartridges (40,41,42) may have printing cylinders (43,44,45,46) of different sizes, and furthermore that a mobile unwind stand may be used to move web material to the printing apparatus, and the web output from the printing apparatus processed by sheet folding techniques.

Abstract: In a retractor reel assembly for a vehicle safety-belt, a locking mechanism is provided to lock the shaft. The locking mechanism includes a disc which normally rotates with the shaft, but which rotates relative to the shaft in response to a predetermined deceleration of the vehicle or in response to rapid withdrawal of the belt. Two locking elements (13,14) are carried on the disc, each defining a recess (21,22) which engages a radial projection (2,3) on the shaft (1) and at least one of the locking elements (13,14) carries a tooth (23) adapted to engage a toothed locking ring (24) which surrounds the locking elements. The locking elements are guided to effect a predetermined motion when the disc rotates relative to the shaft, this motion consisting of an initial linear motion, with the locking elements moving in opposed parallel directions, and a final motion in which the tooth or teeth move with a component tangential to the adjacent locking ring to bring the tooth or teeth into engagement with the locking ring.
