Title: Method of downhole cyclone oil/water separation and apparatus for the same
Inventor: PEACHEY BRUCE RICHARD
IPC: E21B43/38
Filed: 1995-04-10
Granted: 2003-06-10
Abstract: A method of downhole cyclone oil/water separation is described. Firstly, place a cyclone separator downhole in an oil well producing a mixed stream of oil, water and gas.  The cyclone  separator  includes  a  separation  chamber  wherein liquids of differing densities are separated, at least one mixed liquids  inlet through which liquids pass  into the separation chamber, a first outlet for liquids of a first density range to pass from the separation chamber and a second outlet for liquids of a second density range to pass from the separation chamber.  Secondly, connect the first outlet to a recovery conduit extending to surface.  Thirdly, connect the second outlet to a disposal conduit extending to a selected disposal site.  Fourthly, connect the mixed liquids inlet to pumping means and pump a mixed stream of oil, water and gas into the separation chamber of the cyclone separator.   The mixed stream is separated in the separation chamber into a recovery stream of oil with a reduced water content which flows out of the first outlet and along the recovery conduit to the surface and a disposal stream of mainly water which flows out of the second outlet and along the disposal conduit to the selected disposal site.   The described method is particularly for oil wells in which the fluids being separated contain gas.

Granted: 2009-05-26
Abstract: Microspheres are prepared by a process comprising the steps of (i) spray-drying a solution or dispersion of a wall-forming material in order to obtain intermediate microspheres and (ii) reducing the water-solubility of at least the outside of the intermediate microspheres. Suitable wall-forming materials include proteins such as albumin and gelatin. The microsphere have walls of 40-500 nm thick and are useful in ultrasonic imaging.   The control of median size, size distribution and degree of insolubilisation and cross-linking of the wall-forming material allows novel microsphere preparations to be produced. In particular, the microspheres may be 15-20 µm, targeted to selected areas of the body or of prolonged life in the circulation.

Title: Frameless array of hollow fiber membranes and method of maintaining clean fiber surfaces while filtering a substrate to withdraw a permeate
Inventor: COTE PIERRE LUCIEN
IPC: B01D61/18
Filed: 1993-11-15
Granted: 2000-05-23
Abstract: A frameless array unconfined in a modular shell, proves to be a surprisingly effective membrane device for withdrawing permeate from a substrate, the flux through the membranes reaching an essentially constant relatively high value because of the critical deployment of fibers of the array as a skein, arching in a buoyantly swayable generally parabolic configuration within the substrate, above at least one of the array's headers in which the terminal end portions of the fibers are potted. The length of each fiber must be greater than the direct center-to-center distance between the array's pair of headers. For use in a large reservoir, an assembly of the array and a gas distributor means has fibers preferably >0.5 meter long, which together provide a surface area > 10 m2. The terminal end portions of fibers in each header are substantially free from fiber-to-fiber contact. When used in a tank from which the permeate is withdrawn at a location low enough to overcome the transmembrane pressure differential of the fibers, the permeate is withdrawn under a vacuum induced by gravity. To increase flux, a pump may be used which provides a suction less than 75 cm of Hg. When used in combination with a gasdistribution manifold disposed beneath the skein so as to flow bubbles through it, the surfaces of the fibers are surprisingly resistant to being fouled by build-up of deposits of inanimate particles or microorganisms in the substrate. Membranes with high transmembrane pressure differential may be used, if desired, and permeate removed with a vacuum pump.

Abstract: A  filter  for  removing  oscillations  and transients  from vehicle driveline component angular velocity measurement signals.  The filter determines, from successive measurements of angular velocity, any angular  acceleration  of  a  driveline  component. Predetermined sets of unity and fractional multipliers are   assigned  to  respective  ranges   of   angular acceleration.  Each succeeding measurement of angular velocity  is  estimated  by  adding  the  product  of  a selected modifier value and the difference between the currently sensed and the previously estimated values of angular velocity to the previously estimated value of angular velocity.  Multipliers are valued and selected so  that,  when  angular  accelerations  are  detected, relatively large percentages of the differences between currently sensed and previously estimated values of angular velocity are added a relatively small number of times to previously estimated values of angular velocity when the differences are relatively small.  Conversely, relatively small percentages of the differences between currently sensed and previously estimated values of angular velocity are added a relatively large number of times to previously estimated values of angular velocity when the differences are relatively large.
