Abstract: A system and method for fast frequency locking are provided in which the phase difference between first and second synchronization signals is measured (22). The frequency difference between the two signals is then determined (24). The frequency of the second synchronization signal is then set to that of the first synchronization signal (26). Thereafter, the feedback loop of a phase-locked loop circuit is closed, with an error signal representative of the phase difference between the first and second synchronization signals being offset by an amount equal to an error signal generated when the frequency of the second synchronization signal is set to that of the first synchronization signal.

Abstract: The invention relates to a process and to a device for packaging products, particularly cylindrical products such as cigarettes, or the like, in a wrapping sheet, and involves wrapping an ordered group of cigarettes (S) in a wrapping sheet (2) and forming a first tubular wrapping open at its opposing ends and provided with portions (402, 502, 602, 702) projecting beyond the corresponding sides of the group of cigarettes. The ends of the tubular wrapping are closed by the successive folding of the various flaps or various wings (402, 502, 602, 702) forming the projecting portions against the corresponding side of the group of cigarettes (S). The formation of the tubular wrapping open at its ends is carried out in the feed station (A), while the closing of the open ends is carried out completely in only one of the successive stations (P), the whole being done by means of particular shaping, arrangement and operation of movable folding means (6, 15, 25, 26) and stationary folding means (5, 105, 205, 605) and of the forming wheel (1).

Abstract: The housing (1) has an inlet (1.1) for feed of hydraulic fluid and an outlet (1.2) for output of hydraulic fluid. An outwardly toothed pinion (2) is rotatably located in the housing. An internally toothed hollow wheel (3) circulates with the pinion. There is a filling piece with an inner segment (4.1) and an outer segment (4.2) between the pinion and the hollow wheel. The two segments are separated from each other by a peripherally running gap (4.3) and in operation support against a stop pin. A specific fluid pressure is applied in the pressure space (6) of the work chamber of the machine. This acts through holes (3.1) in the hollow wheel on the segments. The radial inner surface of the one segment (4.1) is pressed against the tooth heads of the pinion and the radial outer surface of the other segment (4.2) is pressed against the tooth heads of the hollow wheel. This provides a more or less good seal of the pressure space against the suction space (7).

Abstract: A head-mounted display device (10) offers light weight, a low center of gravity, and low moments of inertia about the azimuthal and elevational axes of head movement. The display device (10) employs an angulated beam splitter mirror (16) disposed between a user's (22) eye (20) and an inner combiner surface (18a) of a visor (28). A projector (36) is carried laterally of the user's eye with a low center of gravity and a position close to the horizontal axis of elevational movement of the head. This projector (36) includes an image source (12) and a compact light-weight relay optics module (14) along with a projection fold mirror (30) disposed at eye level and laterally of the beam splitter mirror (16) to project image light to the beam splitter mirror (16). The beam splitter mirror (16) reflects the light onto the inner surface (18a) of the combiner (18) for reflection back through the beam splitter mirror (16) and to the user's eye (20). Alternative embodiments provide for color correction, or for mono-chrome image projection at even lighter weight. An alternative embodiment provides for both color correction and weight nearly as light as the monochrome version by use of diffractive lenses in the relay optics module.

Abstract: La présente invention concerne un amplificateur pour fibres optiques, un laser ou une source supralumineuse constituée par une matrice de verre au chalcogénure portant des ions trivalents de terres rares et qui est dopée avec un oxyde, à savoir un oxyde de métal. Avec cet appareil, on utilise les propriétés de l'oxyde ajouté pour améliorer la fabrication et le rendement des sources pour guides d'ondes optiques, en particulier pour les applications se situant vers 1,3 νm. Plus particulièrement, l'oxyde élargit la gamme de longueurs d'onde pour l'absorption de pompage et pour l'émission de lumière, accroît le rendement de l'appareil par une modification de la durée de vie de certains niveaux laser et modifie les propriétés du verre pour empêcher la cristallisation pendant la fabrication des fibres. Grâce à l'addition volontaire d'oxyde, l'appareil améliore les propriétés de l'amplificateur, du laser, du verre et des fibres.
