Abstract: A four-function valve for operating a 2-way hydraulic cylinder has a pair of solenoid-operated pilots. The valve also includes a pair of valve members and a pair of poppet members, all slidable within bores in a pair of hollow sleeves. The solenoid-operated pilot valves control pilot pressure communication to the valve members to control movement of the valve and poppet members. Each poppet member has a pair of seats, one engageable with a shoulder on the sleeve to control fluid flow between a pump and the cylinder, the other engageable with an end of the corresponding valve member to control fluid flow between a sump and the cylinder.

Abstract: A fast acting ink valve adapted to be used in conjunction with the nozzle of an ink jet printing system is disclosed. A flexible diaphragm (48) modulates flow through a valve chamber (40). A spring (50) biases the diaphragm (48) to a sealed position to prevent flow. Ink pressure in the marking system unseals the diaphragm (48) permitting flow. Unlike check valves, the invention has minimal pressure drop due to the location of the bias spring outside the inkfiow path.

Abstract: An apparatus for controlling the axial component of the running clearance between a radial inflow turbine and a cooperating turbine shroud. The turbine is fixed to a shaft which is rotatably supported at one end by a frame assembly (11, 31). The shaft and the turbine change in position in the axial direction relative to the shroud with changes in turbine operating temperature. The apparatus comprises a shroud mounting assembly (13), in which the shroud is attached to the mounting assembly, a turbine nozzle assembly (24), which is connected to the shroud mounting assembly, a slidable connection (29) between the turbine nozzle assembly and the frame, providing axial sliding movement, and struts (36) for controlling the axial position of the turbine nozzle assembly relative to the frame. The struts compensate for changes in the turbine axial position and control the relative axial displacement of the shroud. The struts fixedly connect the turbine nozzle assembly to the frame. The struts are positioned to be subjected to temperature changes corresponding to the turbine temperature changes and have a preselected axial length. The struts are also formed from a material having a preselected thermal expansion coefficient.

Abstract: Un mélange spécifique d'un alcane halogéné à tension de vapeur élevée et d'un alcane halogéné à faible tension de vapeur, tels que le Halon 1211 et le Halon 1301, est contenu dans un réservoir (2) et est injecté à l'intérieur et au-dessous de l'obturateur (BOP) (14) dans un puits existant en cas d'incendie. Dans le mesure où il s'agit d'une injection de liquide, les appareils de pompage (4) et les vannes (8) existants permettent d'injecter malgré une contre pression considérable. En outre, le procédé envisage un système d'injection (6) qui ménage un effet venturi de manière à réduire la contre-pression recontrée par les injections destinées à éteindre l'incendie, et à accroître le débit du produit extincteur lors d'un flux important analogue à celui qui se produirait au cours d'une éruption. Dans un mode préférentiel de réalisation, un mélange de Halon 1301 et de Halon 1211, dans une proportion présentant une tension de vapeur plus élevée que de coutume pour un tel mélange, est injecté sous forme liquide à l'intérieur et immédiatement au-dessous de BOP (14) dans le train de tiges et l'espace annulaire lors d'un incendie du puits. Le mélange monte sous forme d'un liquide avec le composant liquide du fluide à l'intérieur de l'espace annulaire, et par suite de l'augmentation de sa tension de vapeur par rapport à celle du méthane ou des gaz inflammables piégés dans le fluide lors d'une éruption, se vaporise et passe à un état d'extinction d'incendie sélectivement et conjointement avec les gaz piégés à l'intérieur du fluide dans le train de tiges. En conséquence, le mélange de Halon est préférentiellement vaporisé avec les composants les plus explosifs et les plus inflammables de l'ensemble du fluide à l'intérieur du train de tiges, permettant une capacité d'extinction d'incendie accrue et suffisante pour empêcher une nouvelle inflammation.
