Inventor: DJAVIT NURI
IPC: A61F5/442
Filed: 1998-02-19
Granted: 2006-05-30
Abstract: A drainage bag (for example a urine collection bag) (10) includes a flexible outlet tube (16) and a pinch valve (18) for selectively pinching the tube closed. The pinch valve includes a pivotal valve member (22) on a first side of the bag, and a support member (20) on an opposite side of the bag. The valve member is pivotally supported on the first side by at least one projection (26) on the support member which projects through an aperture (24) in a web of the bag. During assembly, the support member (20) is firstly fitted to the bag with the projection (26) projecting through the aperture (34), and the valve member (22) is then fitted to the projection (26). In an alternative form, the support has two hook-shaped projections on either side of the outlet tube (16) to which a modified valve member is clipped.

Abstract: The present invention provides a method for obtaining equalized production from deviated wellbores. A plurality of spaced apart flow control device are deployed along the length of the wellbore. The fluid from various zones are drawn in a manner that depletes the reservoir uniformly along the entire length of the wellbore. Each flow control device is initially set at a rate determined from initial reservoir simulations or models. The depletion rate, water, oil and gas content, pressure, temperature and other desired parameters are determined over a time period. This data is utilized to update the initial reservoir model, which in turn is utilized to adjust the flaw rate from one or more zones so as to equalize the flow rate from the reservoir. The present invention also provides a flow control device which includes an outer shroud that reduces the effect of fluid impact on the flow control device and one or more tortuous paths which carry the formation fluid into the production tubing A control unit controls the flow output from the flow control device. The control unit may communicate with surface equipment or act autonomously to take actions downhole based on programmed instructions provided to the control unit.

Abstract: The invention is an apparatus and a method for characterizing the flow of a multi-phase fluid. The fluid is first mixed continuously as it flows from a first to a second end of a first section, such that the fluid is substantially homogeneous at a first point and such that the substantial homogeneity of the fluid is maintained between the first point and a second point in the first section, and a first pressure drop is measured at a first location in the first section between the first and second points. The fluid is second mixed continuously as it flows from a first to a second end of a second section, such that the fluid is substantially homogeneous at a first point and such that the substantial homogeneity of the fluid is maintained between the first point and a second point in the second section, and a second pressure drop is measured at a second location in the second section between the first and second points. Using the first and second pressure drops, a value is determined for a first characteristic and a second characteristic of the fluid. Optionally, the fluid may also be third mixed continuously as it flows from a first to a second end of a third section, such that the fluid is substantially homogeneous at a first point and such that the substantial homogeneity of the fluid is maintained between the first point and a second point in the third section, and a third pressure drop may then be measured at a third location in the third section between the first and second points. A value for a third characteristic of the fluid may then be determined by using the third pressure drop.

Title: Hoppers with applied motion to promote flow
Inventor: JOHANSON JERRY R
IPC: B65D88/66
Filed: 1997-11-03
Granted: 2004-02-17
Abstract: An improvement to a hopper (1) to promote the flow of solid particulate material includes mounting one or more walls (3) of the hopper for limited oscillatory motion in a direction parallel to the wall and perpendicular to the desired flow direction, and then providing an actuator (6) connected to the remainder of the hopper (1) to impart such motion to the wall. The relative motion between the moving wall (3) and the particulate material effectively rotates the friction force to the direction of relative motion, leaving the friction in the desired flow direction approaching zero. As a result, downward flow can occur on walls that are only shallowly inclined. The improvement is applicable to hopper-like structures in railroad cars and ships, where it facilitates discharge onto moving conveyors.

Abstract: Downlink diversity in a CDMA system is provided by employing Walsh codes in conjunction with M transmit antennas at a common base station serving K mobiles, where M may or may not be to equal to K. The present invention provides methods and apparatus for improving downlink diversity in a CDMA system. Each transmit antenna transmits a signal representing the result of the modulation of Walsh codes by data signals for each of the K mobiles, assuming there is data pertaining to a particular mobile. The assignment of Walsh codes is accomplished in accordance with a transmission matrix T. The transmission matrix maps the user data symbols onto the Walsh codes for each antenna and is preferably designed such that its columns are representative of the transmit antennas and orthogonal. Thus, at a given mobile, the mobile need only correlate with M different Walsh codes since each transmit signal received contains a component that is the result of M different Walsh codes having been modulated by a data signal associated with that particular mobile. The set of Walsh codes to select from includes 2[log2(K)] Walsh codes. However, with respect to any given mobile, there is needed only as many different Walsh codes as there are transmit antennas serving the particular mobile. The results of the respective M correlations are combined and, with obtained channel estimates, the receiver estimates the particular data pertaining to that particular mobile so that it can be provided to the user. Also, the present invention provides for various ways to estimate the respective channels between the M transmit antennas and a mobile. It is to be appreciated that the downlink diversity techniques of the invention may be applied to the physical layer proposed in the IS95-C physical layer draft proposal.
