Abstract: A document printer is provided having an aligner mechanism (24) for aligning a document (18) in said printer having a slot defined by first and second walls (20,22). The aligner mechanism (24) comprises first and second control sleeves (40,42) which are keyed to first and second end portions (36,38), respectively, of a first shaft (30) arranged to rotate between first and second positions. First and second levers (52,58) are pivotally mounted on the shaft adjacent to the first and second control sleeves (40,42), respectively, for pivotal movement. The aligner mechanism (24) also includes an aligner bar (44) having first and second leg portions (46,48) secured to the first and second control sleeves (40,42), respectively. The first and second levers (52,58) have projections (70,72) thereon which cooperate with slots (71,73) in the first and second control sleeves (40,42) respectively, to provide a lost motion coupling therebetween. The levers support a second shaft (26-1) which carry pinch rollers (26), each of which cooperate with a corresponding drive roller (28), and form a gripper means (26,28,52,58) for transporting said document therebetween. During movement of the first shaft (30) between the first and second positions, the aligner bar (44) engages the first wall (20), and thereafter, movement of the first shaft (30) resiliently biases the alignment bar (44) against the first wall (20), and cause the levers (52,58) to rotate thereby opening the gripper means (26,28), permitting an edge of said document to be aligned with said aligner bar (44). During movement of the first shaft (30) from the second position to the first position, causes the gripper means (26,28) to close, thereby gripping said document, and causes the aligner bar (44) to move away from the first wall (20).

Title: Operating device in the back cover of a watch case
Inventor: BRISA ANTON
IPC: G04B27/08
Filed: 1991-03-11
Abstract: The function control device in the back cover of the case of a wrist watch consists principally of a central part (11) of the said back cover (10), deformable through the action of an external point (12) which establishes a contact between an extension (22) of the magnetic screen (21) and a track contact (23) of the electronic circuit. Besides improving the appearance of the case, the device according to the invention making it possible to dispense with the winding crown and with any push-buttons generally visible on the periphery of the case, the device cannot be actuated unexpectedly since it is necessary to act on a very specific portion of the back cover of the case, this specific portion being located exactly at the centre of the case back cover, and it is unnecessary to provide it with indexing in rotation. This device is as well suited to cases made from synthetic material as to those made from metal. There is no need for the presence of any additional component on the movement other than those already provided for its operation. <IMAGE>

Abstract: On décrit une sonde pour une machine de mesure à coordonnées ou une machine-outil, équipée d'un boîtier (10) depuis lequel s'étend un stylet qui est mis en contact avec une piéce à travailler (14). Quand le stylet (14) est mis en contact avec la pièce, au fur et à mesure que la sonde est amenée vers la pièce, un certain dépassement de la course est rendu possible grâce à la déflexion d'un porte-stylet (12) qui sort d'une monture cinématique (20, 22) dans un module de dépassement de course (18). Le contact avec la pièce est détecté par des capteurs prévus sur une plaquette, carte ou galette (26). En cas de dépassement de course excessif, et afin de protéger la plaquette fragile (26), une bride (36) du stylet (14) vient en contact avec le boîtier (10A), et une monture cinématique (28, 30) se dégage pour permettre au module de dépassement (18) de se séparer de la plaquette (26). De cette manière, toute charge excessive est reprise entre la bride (36) et le boîtier (10A), et elle n'est pas transmise à travers la plaquette (26).

Abstract: Commutateur de circuit intégré monolithe hyperfréquence comprenant un transistor à effet de champ (16) série ayant un chemin de drain de source (S, D) en série avec un ligne de transmission par induction (17) comportant plusieurs prises (27, 29). Les chemins de drain de source de transistors multiples à effet de champ de dérivation sont reliés aux prises. Les chemins de drain de source des transistors en série et des transistors en dérivation sont polarisés, de sorte que les chemins de drain de source en série et ceux qui sont en dérivation présentent, de manière complémentaire, une impédance élevée et une impédance faible. L'impédance élevée est capacitive, avec une valeur sur l'ordre de grandeur de la ligne de transmission par induction. Dans un premier intervalle de temps, les impédances capacitives et inductrices forment un filtre passe-bas adapté au courant d'alimentation d'une source hyperfréquence à une charge. Dans un deuxième intervalle, le courant de la source hyperfréquence passe par les transistors à effet de champ en dérivation pour être découplé de la charge.
