Patent CA-2186180-C (CA)
Inventor: BUSSEAR TERRY R
IPC: E21B33/14
Filed: 1996-09-23
Granted: 2006-05-16
Abstract: The method includes running a liner, production packer and polished bore receptacle (PBR) into a well on the production tubing string, cementing the liner in place by pumping cement through the production tubing string, setting the packer, and optionally thereafter releasing an upper portion of the tubing string from a PBR. A seal assembly isolates the PBR bore from cement exposure during liner cementation. Annular pressure produces a reverse fluid surge and circulating flow to prevent PBR seal area contamination when the tubing string is lifted away from the PBR. A connecting assembly 12 is suspended from a production tubing string 11 to position a liner 17 in a wellbore. The connecting assembly transmits rotational and longitudinal forces from the production tubing string to properly position and cement the liner in the wellbore. The connecting assembly includes a device 20 to limit torque forces on the tubing string, and a longitudinal slip mechanism 28 permits limited longitudinal movement between the connecting assembly and tubing string. A packer 15 is set to seal between the production tubing string 11 and the well casing. An extended length of tubing 11a extends below the packer to provide a continuous tubing/liner-casing overlap area for cementation.

Title: Reformatting of variable rate data for fixed rate communication
Inventor: WALKER G KENT
IPC: H04N21/4147
Filed: 1996-12-13
Granted: 2000-05-02
Abstract: Variable rate data is reformatted for communication to an external device at a fixed rate. Fixed length packets of the variable rate data are recovered from a multiplex of data packets. A packet start byte is added to the beginning of each of the recovered packets. Fill bits are added to the recovered packets as necessary to maintain the desired fixed output rate if the output rate is greater than an information rate of the variable rate data. The recovered packets with the added packet start byte and fill bits are provided as output to the external device at the fixed rate. The recovered packets with the added packet start byte and fill bits are advantageously encoded using alternate mark inversion (AMI) and binary eight zero substitution (B8ZS). The packet start byte and B8ZS substitution can comprise unique AMI violation sequences.

Abstract: A sand/liquid separator provides for the conditioning of oil sands. Clean sand is separated from the ore and discharged for use as backfill. The sand/liquid separator machine includes horizontal shafts with paddles that act on a fluidized bed. The overall height of the machine is increased over prior art devices so the water volume is expanded. For a given residence time, more sand can be separated out than is otherwise possible. The water-to-sand ratio is an independent variable, water is recycled independent of the sand. The rate of water recycle depends only on the heat input needed and the clay content of the feed. The rate of water input is limited by the rise velocity needed to separate sand larger than forty-four micron from the water/liquid phase. This, in turn, determines the maximum oil sand feed rate based on the total clay in the feed at up to six percent, by weight, of clay in the middlings in the machine. This optimizes the performance of the process to cope with all the variables of heat input, ratio of oil sand feed to water, and clay content of the feed.

Abstract: This invention describes a system and method for monitoring the execution of hybrid source code such as JavaServer Pages (JSP) code. The system comprises a page compiler, which is called by a server for translating JSP code into a servlet for execution by the server.  The page compiler during translation of the JSP code inserts instrumentation in the compiled JSP code for supporting execution tracing by an execution monitor. The execution monitor receives outputs from the page compiler, the servlet and the raw JSP code for displaying selected information about the execution of the JSP code to the developer on a graphical user interface. The execution monitor thus allows the developer to view the correlation between the JSP code, the servlet code and the HTML  code that is generated by the servlet.

Abstract: A transit time ultrasonic flow meter (40) includes a pair of ultrasonic transducers (44, 46) transmitting an ultrasonic signal through a fluid (48) flowing in a conduit (50) and receiving the transmitted ultrasonic signal. A comparator then detects a difference in phase between the received ultrasonic signal and a reference signal having a selected phase shift with respect to the transmitted ultrasonic signal. Control circuitry (52) selects the phase shift of the reference signal based on outputs of the XOR phase comparator in order to maintain the phase shifts detected by the XOR phase comparator. Since the outputs of the phase comparator are correlated to fluid flow, adjusting the phase of the reference signal enhances the inventive flow meter's measurement of fluid flow.
