Abstract: A turbojet includes in succession, from upstream to downstream in the flow direction of a primary air stream: a low-pressure casing, an intermediate casing, and a high-pressure casing that are longitudinally aligned and which jointly delimit an internal annular passage for the circulation of the air stream. The intermediate casing delimits a portion of the annular passage called a gooseneck and includes: an air discharge system able to extract air from the air stream circulating in a first zone of the gooseneck and to discharge it outside the passage, and an air extraction system able to extract air circulating in a second zone of the gooseneck for an air conditioning system, the second air extraction zone being located downstream of the first air extraction zone.

Abstract: A method of forming a seal circumferentially about a liner having pre-formed openings that is positioned in a wellbore includes the steps of running a perforating device and a seal applicator into the slotted liner, the seal applicator carrying a sealing fluid and a pumping mechanism, creating an aperture through the slotted liner at the region by activating the perforating device and pumping the sealing fluid from the seal applicator through the aperture and circumferentially about the liner to form a sealing plug in the annulus between the slotted liner and the wellbore.

Abstract: A temporary heating apparatus comprises a portable heat exchanger which transfers heat from a hot fluid circulating in a primary circulation loop thereof to a heated liquid circulating in a secondary circulation loop thereof. The heat exchanger is connectable to a hot fluid source such that hot fluid from the hot fluid source circulates through the primary circulation loop. A portable remote heating unit comprises a fluid coil releasably connected by flexible conduits to the secondary circulation loop, and a secondary pump is connected to the flexible conduits and the secondary circulation loop to pump heated liquid through the secondary circulation loop, flexible conduits, and the fluid coil of the remote heating unit. The heat exchanger isolates the heating circuit from the hot fluid source, allowing the use of steam as the hot fluid source, and further allowing high pressures in the heating circuit, such as encountered in tall buildings.

Abstract: Methods are disclosed for the simple, rapid, and selective colorimetric detection of carbohydrates, including fructose, glucose, sialic acid, and oligosaccharides. There is no need for any prior hydrolysis or other chemical modification or of the analytes. Resorcinarenes, xanthene dyes, and related compounds, formally produced by the reaction of 2 equivalents of resorcinol and a suitable electrophilic condensation partner, are used as chromophores or fluorophores for the detection of sugars and other carbohydrates.

Abstract: A particulate waste wood fuel comprising wood particles comprising less than 20% water by weight and having a particle size distribution suitable for combustion of the particulate wood fuel in a particulate fossil fuel suspension furnace. A method for making the particulate wood fuel includes shredding of waste wood and drying the shredded waste wood to obtain the desired particle size distribution and water content. A method for producing energy comprises injecting the particulate wood fuel into the combustion chamber of a particulate fuel suspension furnace separately from a particulate fossil fuel which is also injected into the combustion chamber. The particulate fossil fuel and particulate wood fuel are combusted in the combustion chamber in a gas flow through the combustion chamber to form a flame in the gas flow. The wood particles are substantially completely combusted within the combustion chamber while suspended in the gas flow and are not combusted at the furnace wall.

Abstract: This invention relates to a tire with tread of rubber composition quantitatively reinforced with silica and containing only a minimal amount of carbon black, wherein the carbon black is characterized by having a DBP value in a range of about 280 to about 600 and an Iodine Number value in a range of about 550 to about 1200 and where carbon blacks having DBP and Iodine Numbers of less than such values are substantially excluded from the rubber composition.

Abstract: The invention relates to a tire with a tread which is reinforced with a quantitative amount of silica, including a silica coupler, where the tread rubbers are of a blend comprised of styrene/isoprene/butadiene terpolymer rubber and cis 1,4-polybutadiene rubber or styrene/isoprene/butadiene terpolymer rubber, cis 1,4-polybutadiene rubber and isoprene/butadiene copolymer rubber. Optionally, the rubber blend can contain a minor amount of cis 1,4-polyisoprene natural rubber.

Abstract: A method for making a unit including a pressure-sealed container (2) with at least one connecting port (3), and an active solid (1) placed in said container (2). The container (2) is formed directly on a preformed body of the active solid (1) and made of a material having a thermal conductivity of more than 18 W/m. K. The resulting units are particularly useful for making portable air-conditioning devices for garments.

Abstract: In the horizontal parts of deviated wells arranged within a producing formation, good communication between the formation and the wellbore liner is required, and this may be achieved by using a slotted or perforated liner in the horizontal section without any cementing to bond the liner to the wellbore. However, problems can arise if it is desired to work selectively in a zone in the horizontal section, since with a perforate liner there is no way of isolating the zone from the remainder of the well by using internal packers. This problem can be overcome by providing packers around the outside of the liner, this then allows packers inside the liner to be used to isolate a portion of the well. However, these external casing packers must be sealed against the wellbore, they must be positioned in advance, and they substantially increase the cost of the completion.

Abstract: A handle for a ski pole is composed of at least two elements which are assembled together, one of the elements being common to the entire line of handles while the other element can be selected from a group of elements of different sizes to define the ultimate size of the handle. Elements are also provided for assembling them together.

Abstract: The handle of a ski pole has its grip axis offset from the axis of the shaft of the pole and set at least rearwardly thereof to allow the point of the pole to engage the snow substantially more forwardly than an ordinary pole and thus with a more acute angle. The inclination of the grip axis can be adjusted.

Abstract: A ski pole has at its handle end a loop formed by a pair of straps each having one end secured to the ski pole and another free end. One of these free ends passes through a buckle having a holding formation which may be snapped into an elastically deformable seat fixed to the free end of the other strap. The one strap can be slid through the buckle to adjust the size of the loop. In case of emergency a sharp pull exerted between the straps will pull the buckle out of the clip and free the user's hand.
