Title: Apparatus for running two tubing strings into a well
Inventor: SAURER DAN P
IPC: E21B7/08
Filed: 1999-01-29
Granted: 2008-10-07
Abstract: A well has a vertical casing (13) with a window (14), and a lateral wellbore which communicates with the window, and which may have a casing (18) or liner. A window assembly (31) aligned with the window (14) has respective passageways for first (51) and second (52) tubing strings, and has a concave surface (36) for deflecting the first tubing string out into the lateral wellbore. The passageway for the second tubing string has a portion which is inclined at a very small angle with respect to a vertical centerline of the vertical casing. As the first tubing string is run into the vertical casing, a rotational locator (126) is releasably coupled thereto by a soft release coupling mechanism (176). After the locator effects rotational orientation, the coupling mechanism (176) is released and then permits the first tubing string (51) to move therepast without damage. A seal assembly (56) on the first tubing string (51) is covered by a protective sleeve (147) as it is inserted into the well, and exits the protective sleeve (147) after entering the lateral wellbore.

Abstract: A non-conductive frame supports the resonators in a patch antenna assembly.  The frame supports the resonators without making holes in the resonators and thereby avoids the problem of creating unwanted electric field polarizations. Additionally, the frame grasps the resonators in areas of low current density and thereby avoids creating additional disturbances in the radiation pattern. The frames may also include posts that are used to attach the frames to the feedboard without using additional components such as screws.

Abstract: Disclosed is a change indicator (30) for a filter (10) for use in a gaseous circulation system, such as a forced air heating and cooling system. The change indicator includes an air impervious patch (32) that is secured to the filter. The portion of the filter media (12) adjacent to the change indicator changes appearance in response to the accumulation of contaminants at a much slower rate than the remainder of the air filter. The accumulation of contaminants progresses inwardly from the region adjacent the periphery of the change indicator towards the region adjacent to the center. Once the appearance of the filter media beneath the change indicator fully changes from periphery to the center, that is an indication that the air filter is in need of cleaning or replacement.

Abstract: In a label switch communications network, a third level of label is employed in conjunction with a dynamic multiplex constraint-based routed label switched path (CR-LSP) in order to achieve implicit switching at nodes within the network.  Implicit switching occurs when a switching function takes place at a node without the need for any control function being required at that node. A three-layer label stack provided at the edge of the network achieves end-to-end connection oriented behaviour with guaranteed Quality of Service. The use of the three-layer label stack concentrates the control of the network to the two edges of the network and a single central switching stage of the network.

Granted: 2008-01-15
Abstract: The present invention is concerned with a method and apparatus for recycling drilling fluids used in the drilling of wells. The apparatus comprises a tank with a plurality of compartments. Used drilling fluid containing well cuttings or "solids" is pumped into a receiving compartment of the tank and directed towards a flow-reversing barrier. Reversal of the flow causes heavier solids to settle to the bottom of the tank. As fluid fills the receiving compartment, it flows downstream into an adjacent compartment by passing through a flow-restricting baffle that causes more solids to settle to the bottom of the tank. As fluid overflows from compartment to compartment in the tank, it passes through successive flow-restricting baffles causing further solids to settle to the bottom of the tank. When the fluid reaches the collecting compartment of the tank, it is removed to be used again in drilling operations. A conveyor extending along the bottom of the tank is used to move the settled solids to the collecting compartment, from which they are removed and pumped through a centrifuge to recover residual fluids.

Title: Location position system for relay assisted tracking
Inventor: CHIEN CHARLES
IPC: F41G7/20
Filed: 2000-12-20
Granted: 2005-06-21
Abstract: An extensible short-range tracking system is disclosed. The tracking system disclosed is a multi-level tracking sys- tem. At the first level is an RF tag, which is a transmit-only unit that transmits information including minimally an identification number. The transmission from the RF tags are sporadic with timing depending upon the application at implementation. Generally, the transmission timing comprises a transmission, which is repeated periodically at random times. Transmissions from the RF tags are received in a series of relays. The relays may calculate the position of the tags by knowing the position of the relays and the time difference of arrival of the signals from the RF tags by several relays or may pass the information needed to calculate position to a base station. Alternately, the RF tags may generate position informatio n and transmit that information along with the RF tag identifier to the relays. The relays, which may be networked among themselve s, then relay the information from the tags to a base station unit. The base station unit may be part of various applications such as a tire control system in a military application or an inventory system in an industrial application.
