Abstract: A process for manufacturing, in one stage, a tire comprising a carcass reinforcement (1) which is radial in the sidewalls and oblique radially beneath a crown reinforcement (3), composed of at least two layers (31) and (32) of reinforcement elements (310) and (320) which are crossed from one layer to the next, wherein there is pre-shaped to a diameter D1 and by means of a sleeve of at least one shaping ply N, vulcanized and formed of reinforcement elements forming with the circumferential direction an angle alpha1, laid on the building drum T of diameter D, at least the central part of a carcass reinforcement ply (1) formed of radial reinforcement elements (10) forming with the circumferential direction an angle ∓beta1. There is laid on the central part at least one crown ply (31, 32) formed of reinforcement elements (310, 320) oriented relative to the circumferential direction at angles ±gamma1 (mugamma1), gamma1 being little different from beta1. Shaping is effected by bringing the internal diameter D1 of the cylindrical blank to the internal diameter D2, which is the diameter of the vulcanized tire.

IPC: H04B7/005
Filed: 2001-05-25
Abstract: A communication system (10, 68) includes a plurality of different, spectrall y separated air-interfaces providing different services from co-located base sites (70-76). One of these air-interfaces, which may be CDMA, operates a universal frequency-re-use pattern across multiple cells (80-88, 90), wherea s other air-interfaces, such as GSM, have carrier frequencies that a cell re-u se pattern. A subscriber unit (12-16) within the system (10-68) monitors an interference environment and path loss of at least some of the various different services to infer propagation conditions that are likely to be experienced within a spread spectrum service supported by the universal frequency re-use pattern. Armed with an assessment of fade (82-86) condition  within the system as a whole, implied by time and path loss from broadcast signals from different services, the subscriber unit can regulate and contro l its power transmission. Spread spectrum communication to a distant base station can be safe in the knowledge that high power transmissions from the subscriber are subject to deep fade when viewed by near-in base sites. Near- far problems associated with high power transmissions to near-in base sites can therefore be mitigated based on a level of confidence that is found in t he fade condition determined bypath loss in services ancillary to the spread spectrum service.

Title: Method and plugging material for reducing formation fluid migration in wells
Inventor: SVINDLAND ALF
IPC: E21B33/13
Filed: 2000-09-22
Abstract: The invention pertains to a method to hinder/reduce migration of formation fluids in wells, primarily in connection with plugging of wells. A preferably poorly sorted particulate matter consisting of naturally occurring and/or synthetically produced granular material, eventually such material suspended in a suitable liquid, is placed in or around remaining casings (10, 12, 14 and 16) and pro-duction tubing (28), and eventual other remaining equipment, in all or in portions of the well. The particulate material mentioned can re-place, eventually be utilised in combinations with, conventional mechanical plugs (40, 44, 48) and cement plugs (42, 46, 50). The partic-ulate material plug (52) must over a sufficient length in the well be suitably sorted, packed and eventually be provided with preferable chemical/physical properties, such that the permeability of the plug (52) becomes sufficiently small. This results in that the time required for formation fluids to migrate through may become several thousand years. The plug of particulate matter (52) can also change in shape and adapt to eventual geometry changes in the well, for example as a consequence of displacements in the Earth's crust or corrosion of metals in the well, and thereby hinder/minimise eventual leaks.

Abstract: A method of charging fibrous webs with nonaqueous polar liquids. A web (20) that contains nonconductive fibers is wetted with a nonaqueous polar liquid (14). The web (20) is then substantially dried (22) to provide a fibrous electret web. The fibrous electret web can be used as a filter in a filtration face mask (40) that is adapted to cover the nose and mouth of the wearer. The present method has the advantage over known charging methods in that the nonaqueous liquid requires less energy for drying than is required for aqueous liquids. Additionally, many filter webs can be directly wetted with nonaqueous liquids, which cannot be easily wetted with aqueous liquids.

IPC: B65H75/44
Filed: 2002-08-08
Abstract: A hose cart combining the features of an off-set handle, to permit any easier retrieval of paid out hose, a hose tracker, to permit hose to be neatly wound onto a reel, and a storage system comprising a protective housing, to provide storage and protection for a hose kept within, is provided. The invention includes the use of a crank to turn a reel which causes paid out hose to be drawn into the protective box onto a reel. The use of a plurality of gears permits the crank to be offset from the center of the reel, such that it is elevated to a more convenient cranking position. Further, the use of gears permits the same movement of the crank, which causes hose to be collected, causes a hose guide to move laterally, along the axis of the reel, such that hose is neatly layered onto the reel.

Abstract: A silencer (143) is disclosed that reduces the acoustic energy of a fluid mixture (111) of a liquid coolant (109) and of exhaust gas (107) from an engine. The engine may be a marine engine. The silencer (143) according to this aspect includes a receiving chamber (171) that receives the fluid mixture (111) and exhaust gas (107), at least one lifting conduit (175); and a separation chamber (173). The lifting conduit (175) has a receiving portion (177) with a first opening (179) and an expelling portion (181) with a second opening (183). The receiving portion (177) is fluidly coupled with the receiving chamber (171) so that the fluid mixture (111) enters the first opening (179) from the receiving chamber (171) and is lifted through the lifting conduit (175) to the expelling portion (181). This lifting may be accomplished, at least in part, by dynamic effects. The separation chamber (173) is fluidly coupled with the second opening (183) of the lifting conduit (175), and has at least one interior surface (185). The expelling portion (181) of the lifting conduit (175) is disposed so that fluid mixture (111) expelled from the second opening (183) is directed toward the at least one interior surface (185) of the separation chamber (173).  The at least one interior surface (185) may dynamically separate, for example by linear momentum effect or centrifugal effect, at least a portion of the exhaust gas (107) from the fluid mixture (111).
