Patent CA-2385739-A1 (CA)
Inventor: HARDING DARIN M
IPC: E21B21/06
Filed: 2002-05-09
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.

Inventor: SPRINGMEYER STEPHEN
IPC: H05B37/02
Filed: 2000-02-03
Abstract: A method system for tracking the state of an entity (e.g., an object) on behalf of a client (e.g., an application program). The states of an entity include up and down. The tracking system of the present invention receives a request from a client to track the state of an entity. The tracking system then watches the state of the entity to detect when the entity enters the up state. When the entity enters the up state, the tracking system performs a behavior that is specified by the client to be performed when the entity enters the up state. When the entity is in the up state, the tracking system monitors the state of the entity to detect when the entity enters the down state. When the entity enters the down state, the tracking system performs a behavior that is specified by the client to be performed when the entity enters the down state. When the tracking system receives a request from the client for a pointer to the entity, the tracking system determines the current state of the entity and either provides a pointer to the entity or indicates that a pointer is not being provided.

Abstract: A method and apparatus to reduce background noise in speech signals in order to improve the quality and intelligibility of processed speech. In mobile communications environment, speech signals are degraded by additive random noise. A randomness of the noise, which is often described in terms of its first and second order statistics, make it difficult to remove much of the noise without introducing background artifacts. This is particularly true for lower signal to background noise ratios. The method and apparatus provides noise reduction without any knowledge of the signal to background noise ratio.

Title: Grating-based optical device with axial compression thermal compensation
Inventor: SIRKIS JAMES S
IPC: H01S3/102
Filed: 2001-02-22
Abstract: A temperature compensated optical device includes a compression-tuned glass element (10) having a Bragg grating (12) therein, a compensating material spacer (26) and an end cap (28) all held within an outer shell (30). The element (10), end cap (28) and shell (30) are made of a material having a low coefficient of thermal expansion (CTE), e.g., silica, quartz, etc. And the spacer (26) is made of a material having a higher CTE, e.g. metal Pyrex®, ceramic, etc. The material and length L5 of the spacer (26) is selected to offset the upward grating wavelength shift due to temperature. As temperature rises, the spacer (26) expands faster than the silica structure causing a compressive strain to be exerted on the element (10), which shifts the wavelength of the grating (12) down to balance the intrinsic temperature induces wavelength shift up. As a result, the grating (12) wavelength is substantially unchanged over a wide temperature range. The element (10) includes either an optical fiber having at least one Bragg grating (12) impressed therein encased within and fused to at least a portion of a glass capillary tube or a large diameter waveguide (or cane) with a grating (12) having a core (11) and a wide cladding, which does not buckle over a large range of compressive axial strains. The element may have a "dogbone" shape to amplify compressive strain on the grating (12). The device (8) may also be placed in an axially tunable system that allows the wavelength to be dynamically tuned while remaining athermal. In addition to a grating, the device may be an athermal laser, DFB laser, etc. Also, the entire device (8) may be all made of monolithic glass materials.
