Abstract: An apparatus 30 for isolating at least a portion of a tubular for use in a wellbore comprising a first, inner tubular in the form of carrier tube 32 and a second, outer tubular in the form of protective shroud 34, coupled to the carrier tube 32. One or more aperture 46 is provided in a wall of the carrier tube 32 for permitting fluid transfer through the tube 32 and one or more aperture 50 is provided to permit fluid transfer through the shroud 34. A seal member in the form of a sealing layer 36 is disposed on a surface of the shroud 34, the sealing layer 36 defining a first configuration permitting fluid flow through the apertures 46,50 and, on exposure to a selected reactant, adopting a second configuration to restrict fluid flow through the apertures 46, 50, the sealing layer 36 adapted to return from the second configuration to the first configuration where concentration of the selected reactant falls below a selected threshold.

Abstract: A process for making absorbent cellulosic paper products such as sheet for towel, tissue and the like, includes compactively dewatering a nascent web followed by wet belt creping the web at an intermediate consistency of anywhere from about 30 to about 60 percent under conditions operative to redistribute the fiber on the belt, which is preferably a fabric. In preferred embodiments, the web is thereafter adhesively applied to a Yankee dryer using a creping adhesive operative to enable high speed transfer of the web of intermediate consistency such as a poly(vinyl alcohol)/polyamide adhesive. An absorbent sheet so prepared from a papermaking furnish exhibits an absorbency of at least about 5 g/g, a CD stretch of at least about 4 percent, and an MD/CD tensile ratio of less than about 1.1, and also exhibits a maximum CD modulus at a CD strain of less than 1 percent and sustains a CD modulus of at least 50 percent of its maximum CD modulus to a CD strain of at least about 4 percent.

Abstract: Photodetector arrangements, designs and fabrication techniques are described related to semiconductor nanostructures. Arrangements and techniques are described which utilize a nano-patterned template for growing semiconductor nanostructures and/or heterostructures. Resulting photodetectors are also described.

Abstract: A sub-sea well intervention vessel includes a dynamically positionable tanker and direct well intervention equipment mounted on the tanker deck. The intervention equipment includes drilling equipment for performing underbalanced drilling and hydrocarbon liquid separation. A separate production riser is provided so that simultaneous drilling and production can be performed via separate risers. The driller riser is selectively disconnectable from the well so that the tanker can be dynamically repositioned over the well. A turret mooring system is provided such that the production riser can remain in operation during repositioning about the turret. The hydrocarbon liquid separator is connected to a separator of the production plant.

Abstract: A nickel based single crystal superalloy comprising 7-9 wt % cobalt, 3.5-4.5 wt % chromium, 0-2.4 wt % molybdenum, 4-8 wt % tungsten, 3.5-6 wt % rhenium, 5-6.5 wt % aluminium, 6.5-8.5 wt % tantalum, 0-0.2 wt % hafnium and the balance nickel plus incidental impurities. The nickel based single crystal superalloy is suitable for use as a gas turbine engine turbine blade or turbine vane. It is of particular us on cooled turbine blades and turbine vanes which have ceramic thermal barrier coatings, because the superalloy is compatible with the ceramic thermal barrier coating to minimise spalling. The superalloy has better mechanical properties than other second-generation single crystal superalloys and has better creep strength and oxidation resistance.

Abstract: A modular unit (1) for transporting work pieces (40) and suitable for use in an array of such units, comprises a top (5); transportation means (10) which propel the work pieces onto and/or off said top (10) and against which the work pieces rest when located on the top (5) of the unit, the transportation means (10) being part of said top (5); in which the transportation means occupy one or more regions of the top (5) of the unit (1) whilst one or more remaining regions of the top are not occupied by transportation means (10) but are suitable for receiving a work piece treatment device.

Abstract: A ridge end assembly for a hipped roof is disclosed in which panel-supporting elongate members of the hipped roof are connected to the ridge end by connectors which are provided with means for locating lengths of sealing material betwen panels supported, in use, by the panel supporting members and an overlying ridge end cap. In one embodiment, the ridge assembly can include a ridge structure, a ridge cap for fitting atop the ridge structure, the ridge cap having a channel at its underside, and at least one fastener having an enlarged part for reception and retention in the channel, the fastener comprising a flexible tie by means of which the cap can be drawn into place on the ridge structure and then secured by a locking member co-operating with the tie.

Abstract: An interface device, for use in a data management system, interfaces between a plurality of application programs, each requiring a device dependent message to run a transaction, and a client device capable of requesting a transaction to be run. The interface device receives device independent messages, from a client device, each containing a keyword, and translates these into device dependent messages which are sent to application programs. The device dependent message returned from the application program is translated by the interface into a device independent message before being sent to the client device.

Abstract: A fuel injection system of the single point, throttle body type in which a fuel injector is located centrally above the inlet to an air throttling body that contains a variable venturi consisting of a plug and nozzle assembly wherein the plug includes a fuel dispersion plate directing the fuel towards a movable nozzle together defining a convergent-divergent flow air that is variable in area in response to the dynamic pressure of the air against it at higher air flows or alternately responsive to the suction of the engine at low air flows to be moved to a position providing essentially a constant air velocity flowing past the fuel under all conditions of operation to shear the fuel and thereby atomize the same for an economical and efficient operation of the engine.
