Abstract: In an apparatus for winding and/or unwinding flat material webs onto and/or from a core member mounted rotatably about its longitudinal axis, a clamping device is mounted on each of two support units which are arranged at a distance from one another and are adjustable in the axial direction, each clamping device preferably being assigned a correspondingly designed and arranged pressure-monitoring device. A preferred exemplary embodiment of the clamping device (210, 210') comprises essentially a holding member (215) with cylindrical housing (220) formed on, and a piston element (240) which is in work connection with a cylindrical core (225) and is arranged in a chamber (245'') formed from a cylindrical distance piece (245) and two lateral closure plates (250, 260). The piston element (240) can be acted upon, on one side or the other according to direction of movement, by a pressure source, via correspondingly arranged and designed duct systems (201 and 202, 203, 204, 205), for an axial push or pull movement. By means of the axial push or pull movement of the cylindrical core (229) in work connection with the piston element (240), correspondingly arranged clamping elements (230) in the cylindrical housing (220) are moved radially outwards or inwards and brought into or out of engagement with the core member for fastening. <IMAGE>

Abstract: An apparatus is provided for separating nitrogen (27) gas from methanol liquid (26) in a furnace hardening systm. The furnace (25) is housed in a building and connected by a piping system to a methanol storage tank located outside the building. The tank (26) is capped with nitrogen (27) to pressurize the system at high pressure and a pressure regulator (30) reduces the pressure at the furnace. A flowmeter (32) unit controls the flow rate. The gas separating appartus (1) includes a vessel (2) having a liquid inlet (4) and a liquid outlet (6) in the lower end. The methanol containing nitrogen is introduced under pressure into the inlet (4) and is discharged from the outlet at a lesser flow rate to provide an accumulation of the liquid in the vessel, while the nitrogen gas is released from the liquid and collects in the headspace of the vessel. A float (15) is disposed in the vessel and floats on the accumulated liquid in the lower end of the vessel. A switch mechanism is associated with the float and when accumulated gas lowers in liquid and float to a predetermined position, the switch mechanism acts to open a valve (22) in a gas outlet to vent the nitrogen from the vessel to the atmosphere.

Abstract: An apparatus for heat treating contaminated particulate material and more particularly, an appar­atus for reclaiming foundry sand. The apparatus includes a heated, inclined rotary drum (3) and an auger (2) projects into the upstream end of the drum (3) and serves to feed material to the drum (3). The auger (2) includes a spiral flight (7) carried by a hollow shaft (8) and a blower (18) is connected to the outer end of the hollow shaft (8) so that air is supplied through the shaft (8) into the drum (3). A seal is provided between the non-rotating auger housing (9) and the drum (3), and the seal includes an annular bearing plate mounted on the end of the drum (3) while a sealing ring is connected to the auger housing (9) and is biased against the plate to provide a seal. The excess air in the heated drum (3) burns off the organic contaminates from the particulate material and calcines the mineral contaminates. The treated particulate material is transferred from the downstream end of the drum (3) to a second cooling drum (5) and air is passed through the second drum (5) countercurrently to movement of the particulate material to cool the material.

Abstract: Un procédé et un appareil de lithotritie laser permettent de soumettre des matières calcifiées dans le corps d'un mammifère, notamment le corps humain, à deux faisceaux de lumière laser pulsée qui se chevauchent dans le temps et dans l'espace dans les plages de longueurs d'ondes comprises entre 300-450 et 600-900 nanomètres. Dans un premier mode de réalisation, les deux faisceaux de lumière laser sont formés par un laser déclenché (19) associé à un cristal de doublement des fréquences (6). Dans un deuxième mode de réalisation, chaque faisceau de lumière laser est formé par un laser déclenché indépendant (15 et 16), puis les faisceaux sont combinés par le miroir (12). Dans les deux modes de réalisation, on utilise un miroir frontal (7) afin de diriger les faisceaux laser vers un système d'administration endoscopique (8).

Abstract: Un système de commande émet des entrées de commande des pales individuelles d'un rotor d'hélicoptère à quatre pales. Des dispositifs d'actionnement d'une série à autorité limitée situés dans une partie non-rotative de l'hélicoptère sont entraînés par un ordinateur qui reçoit des entrées des capteurs individuels de chaque lame et des capteurs de stabilisation de l'aéronef, additionnées à des entrées de commande émises par le poste de pilotage. Les mouvements obtenus sont transmis aux pales du rotor par un disque classique en nutation qui entraîne quatre pales du rotor et par un manchon différentiel de translation et des liaisons de sommation qui entraînent uniquement deux pales. Le manchon différentiel lève ou abaisse axialement le disque en nutation. Il a été démontré mathématiquement que les mouvements combinés du disque en nutation et du manchon différentiel permettent d'obtenir une commande du pas de calage de chaque pale. Les commandes calculées pour chaque pale sont converties du cadre rotatif de référence en commandes cycliques, collectives et differentielles du pas de calage des pales dans le cadre fixe de référence au moyen d'une matrice de transformation de coordonnées.

Abstract: An optical disc record and playback apparatus in which laser light is focused to a small spot on an optical disc for the purpose of recording and reproducing signals encoded thereon is adapted so that it is possible to record and playback erasable discs, as well as write-once discs. 
     When a disc is first inserted into the record and playback apparatus, data written on a control track of the disc is read to identify the disc type, i.e. whether the disc is erasable or a write-once disc. Optimum recording and playback parameters are then set depending upon the type of disc, thus providing for stable recording and playback of optical discs of different types in a single record and playback apparatus. 
     An optical disc for use in the apparatus has data representative of the optical sensitivity of the disc recorded thereon during manufacture. The data is read by the record and playback apparatus and used to adjust the optical power during recording of information so as to compensate for differences in the optical sensitivities of different discs which may result during manufacture.
