Abstract: Dans le cas d'un dispositif de chargement à répétition (3) destiné à des armes à feu portatives automatiques lesquelles possèdent une culasse mobile dans leur sens longitudinal, en particulier destiné à un fusil automatique, comportant un levier d'armement pivotant (4) qui, en position de repos, s'étend dans le sens longitudinal de l'arme et peut être amené par pivotement à une position d'utilisation dans laquelle il est chargé par un ressort (6) tendant à le faire pivoter en avant et à le maintenir dans une position de repos, on obtient une construction simple du dispositif de chargement laquelle permet de faire coulisser la culasse tant dans le sens du réarmement qu'en sens inverse, ainsi qu'une sécurité plus grande contre les risques de blessure du tireur lors du tir, grâce au fait que le levier d'armement (4) est logé pendant sa position de repos à l'intérieur du profil extérieur de l'arme et disposé sur la culasse directement ou au moyen d'une pièce intermédiaire. Du fait que le dispositif de chargement à répétition (3) est fixé sur la culasse, on évite une construction compliquée avec des éléments d'arme supplémentaires, ce qui réduit le poids de l'arme et sa sensibilité aux dérangements.

Abstract: Procédé et dispositif pour le fixage de fil textile (1) à enrouler sur des bobines, au moyen d'une cloche à vide (36) chauffable eet se prêtant au vide, et qui peut abriter une ou un faible nombre de bobines. De l'eau et de la vapeur saturée sont contenues dans un générateur de vapeur à une température égale à ou légèrement supérieure à la température présélectionnée de la vapeur et à une pression égale à la pression de la vapeur à la température de vaporisation. On réalise le vide dans la cloche renfermant les bobines à une pression sensiblement inférieure à la pression de la vapeur. Une soupape de commande dans une conduite de raccordement entre la cloche à vide et le générateur de vapeur est alors ouverte. Puisque la cloche à vide est également préchauffée à sensiblement la température de vaporisation, la quantité d'eau nécessaire pour remplir la totalité du système de vapeur saturée à la température de vaporisation est très rapidement transformée en vapeur dans le générateur de vapeur. Le fil est ainsi vaporisé par cycles d'une durée approximative de deux minutes.

Abstract: This invention relates to a recording sheet, more particularly, a transparent recording sheet suitable for use with ink-jet printers. Transparencies for use with overhead projectors can be produced by imagewise deposition of liquid ink of various colors onto thin, flexible, transparent polymeric sheets. In the case of imaging onto polymeric film, some means of absorbing aqueous liquids is needed if satisfactory drying of the image is to occur. Because simple polymeric systems are generally either limited in absorbency or in structural integrity, compositions useful as transparent liquid absorbent materials have been formed by blending a liquid-insoluble or low absorbent material with a liquid-soluble, or high absorbent material. A problem that frequently arises in the formulation of polymer blends is the incompatibility of the polymers being blended. When attempts are made to blend polymers that are incompatible, phase separation occurs, resulting in haze, lack of transparency, and other forms of inhomogeneity. This invention provides a transparent recording sheet suitable for ink-jet printers comprising a transparent support bearing on at least one major surface thereof a light transmissive ink-receptive layer containing a hydrophilic polymer crosslinked by polyfunctional aziridine. The recording sheet remains transparent even after ink is absorbed and provides a fast drying, durable, non-tacky transparency suitable for use with an overhead projector.

Abstract: The velocimeter measures the absolute speed V of a vehicle (100) being checked. It comprises, on board a control vehicle (200), a first velocimeter (210) for measuring the reference speed VR of the said control vehicle (200) and a second, Doppler effect, velocimeter (220) for measuring the speed dV of the said vehicle (100) being checked relative to the control vehicle (200). A computer outputs the required absolute speed V = VR + dV. The first velocimeter (210) is a Doppler effect velocimeter which continuously measures the reference speed VR of the said control vehicle (200) as long as the second Doppler effect velocimeter (220) detects a negative relative speed dV. The first velocimeter (210) stops measuring the reference speed VR and the second velocimeter (220) measures the relative speed dV when the second velocimeter (220) detects a positive relative speed dV. The first velocimeter (210) once again measures the reference speed VR as soon as the second velocimeter (220) detects a new negative relative speed dV. Application to speed checks of vehicles travelling on the public highway. <IMAGE>

Abstract: The linear actuator consists of an electric motor (13, 20), a system (4) for moving a rod (42) and a return device (3). For any given angular position of the rotor (20), the system for moving a rod imposes a longitudinal axial position on a rod able to work an arbitrary control. This transmission of motion is secured via a screw-nut link (43, 45) as well as via a pin link (41, 44a). The return device, consisting of a spiral spring leaf (30) one end of which is joined to the frame (10) while the other end is fixed to the rotor, makes it possible to return the rotor and the movable rod respectively, to a start position should the supply voltage disappear. Such a device is able to control an element such as a shutter, a valve or a ventilation flap having imperatively to come back to a specified position should the voltage disappear, in the event of fire for example. <IMAGE>

Abstract: Procédé de préparation de peracétyloxazolines à partir de saccharides de peracétyle. Le procédé consiste à faire réagir le matériau de départ, un saccharide de peracétyle, avec une combinaison de réactifs pour directement produire l'oxazoline de peracétyle. Ce procédé peut servir à activer les oligosaccharides, un oligosaccharide contenant un GlcNAc réducteur en fin de chaîne étant activé par la formation d'une oxazoline au niveau de cette fin de chaîne, puis couplé à un spacer bifonctionnnel pour donner un conjugué oligosaccharide/spacer. Ensuite, on couple ce conjugué à une protéine, telle que le facteur stimulateur des colonies de granulocytes ou l'interféron-gamma, pour donner un conjugué néoglycoprotéique. On a prévu un procédé de formation de conjugués néoglycoprotéiques aptes a améliorer les caractéristiques biologiques et physiochimiques de la protéine. Par example, on peut améliorer la durée de vie de sérum ou l'efficacité de l'administration du peptide à un organe cible ou à une cellule cible.
