Abstract: The invention concerns an industrial robot comprising a column (10,12) housing a first group (17) of coaxial hollow shafts rotatably coupled to a first articulated joint (73) positioned at about 60° to the first group (17) of hollow shafts. A second group (89) of coaxial hollow shafts receives the rotating movement from the first articulated joint (73) and transmits it to a second articulated joint (108), also arranged in slanted relationship at 60°. A third group (126) of coaxial hollow shafts receives the rotating movement from the second articulated joint (108) and transmits it to a third (134) articulated joint which in turn is connected to an end bush (144) supporting implements or operative tools. 
     The invention is of particular advantage thanks to its high mobility and to the particular orientation in the space allowed to the several articulated joints.

Abstract: Comparé aux gyroscopes à fibre optique de l'art antérieur, cet appareil se caractérise par une stabilité et une reproductibilité améliorées de sa polarisation, et par un taux fortement réduit d'extinction de la polarisation. Il comprend un substrat formé de préférence de verre de silice. Une première fibre optique pourvue d'une paire de coupleurs optiques espacés de couplage à une deuxième et à une troisième fibres est rigidement montée sur le substrat. Des surfaces planes sont formées dans des régions prédéterminées de la gaine des fibres fixées. Les coupleurs optiques, les polariseurs et les autres composants utilisés dans un détecteur de rotation sont agencés sur les surfaces planes de la gaine desdites fibres. Afin d'éliminer les composants indésirables de polarisation linéaire des signaux optiques guidés par les fibres, tout en permettant à un composant voulu de polarisation linéaire de se propager sans atténuation, l'axe de transmission des polariseurs formés sur les fibres est aligné avec un axe de biréfringence de la fibre correspondante. Un enroulement de fibre optique détecteur de la vitesse angulaire guide la lumière dans les deux sens entre la première et la troisième fibres optiques, alors que la première et la deuxième fibres optiques coopèrent avec le deuxième coupleur optique afin d'introduire des signaux optiques se propageant en sens inverse dans l'enroulement détecteur. Les coupleurs couplent également des signaux optiques se propageant en sens inverse afin de produire des signaux d'interférence qui constituent des mesures de la vitesse angulaire.

Abstract: In a refrigeration system, pressure and temperature of the refrigerant are measured before the expansion device (14). With the aid of these measured values, the pressure of the refrigerant is adjusted before expansion (14) by control of the capacity on liquefaction (7) in such a manner that the refrigerant is always in liquid state before expansion (14). As a result, the temperature on liquefaction (7) can, within a wide range, be adapted variably to the temperature of the external air used for leading off the liquefaction heat. <IMAGE>

Abstract: To operate an RF antenna of a nuclear spin tomograph which is connected to an unbalanced line and in which a sheath wave barrier is provided between the RF antenna and the line, the inductance L of the sheath wave barrier is designed, according to the invention, as a toroid (2). In this embodiment, a low-leakage sheath wave barrier is obtained which is particularly suitable for circularly polarised resonators. It suppresses difference currents caused by imbalances and consequently acts as a balun at the same time.

Abstract: Textiles prone to fading can be washed without fading in aqueous washing lyes containing anionic tensides and non-ionic tensides with an HLB value greater than 11 as well as water-soluble polymers which inhibit fading. To this end, the ratio of non-ionic to anionic tensides in the washing lye is adjusted so as to lie in the range 1:0.3 to 1:3, preferably 1:0.5 to 1:2. This ratio is obtained for example by adding suitable quantities of a washing additive containing non-ionic tensides and, if necessary, water-soluble polymers, to washing lyes containing anionic tensides.

Abstract: A method and the related system for sampling solid materials. Materials as continuously manufactured from a compression molding machine (1) (e.g. medical tablets) are sampled at fixed intervals and the materials (M) thus sampled are fed into a transport pipe (4) so as to be transferred by being accompanied by a transport plug (5) into an inspecting station at low speed from its stand-by position in the pipe (4) when a gas control means (GC) is set in a feed mode. After transferring sampled materials (M), the transport plug (5) left at its terminal position in the transport pipe (4) is automatically returned to the stand-by position through the transport pipe (4) when the gas control means (GC) is set in a suction mode. By executing the above steps repeatedly, sampled materials (M) are successively transferred into the inspecting station by being accompanied by the transport plug (5) under unmanned operation.

Abstract: Method and system for suppressing interferences in an X-ray scanner characterised in that the average value of the signals from the first ten exposures is calculated in a circuit (26). This average value is subtracted from the signals from the first exposure V1 in a circuit (27) so as to obtain the high-frequency components H1 which are thought of as interferences. The signals H1 are filtered in a high- pass filter before being subtracted from the signals from the exposure V1 and obtaining signals V'1 free of disturbing components. The signals V'1 are processed in a sequential circuit (31) to obtain signals V'2 free of disturbing components and so on and so forth for the signals from the other exposures V3 to Vm.

Title: Procedes de traitement de pate a papier
Inventor: MINTON MARY LADELLE
IPC: D21D1/20
Filed: 1989-04-14
Abstract: Le traitement par déshydratation et compactage d'un mélange de pâte à papier d'une consistance, après séchage au four, allant jusqu'à 50 %, consiste à tordre et à vriller les fibres de manière permanente et pratiquement irréversible lorsqu'on les soumet ensuite aux différentes étapes de la fabrication de papier. Le dispositif préféré pour conférer une telle torsion et un tel vrillage permanents est un alimentateur à vis. La pâte ayant subi ce traitement présente une aptitude au drainage meilleure dans la partie humide d'une machine à papier. De plus une pâte ainsi traitée perd sa vapeur d'eau plus facilement dans la partie séchoir que de la pâte non traitée, et a par conséquent pour résultat une consommation d'énergie moindre dans la partie séchoir d'une machine à papier. La pâte traitée selon l'invention présente également un meilleur pouvoir absorbant. Les produits de papier mousseline ou d'autres papiers doux produits à partir de pâte de bois résineux traitée selon l'invention présentent une douceur sensiblement supérieure par rapport à une pâte de bois résineux non traitée. La pâte traitée selon l'invention est aussi utile pour améliorer les propriétés, par exemple le volume, d'autres produits de papier.
