Patent CA-2291600-A1 (CA)
Inventor: KOSMALA ALEXANDRE G E
IPC: E21B4/20
Filed: 1999-12-06
Abstract: An actively controlled rotary steerable drilling system for directional drilling of wells having a tool collar rotated by a drill string during well drilling. A bit shaft has an upper portion within the tool collar and a lower end extending from the collar and supporting a drill bit. The bit shaft is omni-directionally pivotally supported intermediate its upper and lower ends by a universal joint within the collar and is rotatably driven by the collar. To achieve controlled steering of the rotating drill bit, orientation of the bit shaft relative to the tool collar is sensed and the bit shaft is maintained geostationary and selectively axially inclined relative to the tool collar during drill string rotation by rotating it about the universal joint by means of an offsetting mandrel that is rotated counter to collar rotation and at the same frequency of rotation. A drilling fluid driven turbine in combination with an alternator produces electric power which is used to drive an electric motor. The electric motor provides rotation to the offsetting mandrel with respect to the tool collar and is servo-controlled by signal input from position sensing elements such as magnetometers, gyroscopic sensors, and accelerometers which provide real time position signals to the motor control. In addition, when necessary, a brake is used to maintain the off-setting mandrel and the bit shaft axis geostationary, the brake being servo-controlled by signal input from position sensing elements which provide real time position signals to the brake control. Alternatively, a turbine is connected to the offsetting mandrel to provide rotation to the offsetting mandrel with respect to the tool collar and a brake is used to servo-control the turbine by signal input from position sensors which provide real time position signals to the brake control.

Abstract: A power electrical enclosure includes a portion into which substantially planar assemblies can be inserted and a portion in which power components can be conventionally mounted to one or more walls of the enclosure. The assemblies include power electrical components and/or connections, which are mounted to one surface of the assembly to effectively use the volume within the enclosure. A heat sink can be provided on one or more assemblies and thermally connected to components thereon. An aperture is provided through the enclosure such that the heat sink extends outside of the enclosure when the assembly is inserted, thus permitting passive radiation of waste heat outside of the enclosure. The enclosure is believed to be particularly suitable for use with industrial manufacturing equipment such as injection molding machines and the like.

Title: Coated substrate drying system with magnetic particle orientation
Inventor: MUNTER JOHN D
IPC: F26B25/00
Filed: 1997-11-06
Abstract: Drying a coated substrate (16) which includes magnetic particles includes a condensing surface (22) spaced from the substrate (16). This creates a longitudinal gap (h1) between the substrate (16) and the condensing surface (22). Liquid (18) is evaporated from the substrate (16) to create a vapor and the vapor is transported to the condensing surface (22) without requiring applied convection. The vapor is condensed on the condensing surface to create a condensate which is removed from the condensing surface (22). Removal is performed, using more than gravity, without allowing non-uniformities of the condensate film to occur. The magnetic particles are oriented on the coated substrate (16) by subjecting the coated substrate (16) to a magnetic filed created at a location outside of the dryer space.

Abstract: A displacement sensor includes a magnet assembly having a housing for mounting to one of first and second relatively moveable elements. First and second magnets are mounted to the magnet assembly housing so that the north pole of one magnet confronts the south pole of the other magnet, and vice versa. The first and second magnets form a longitudinal space between them. A flux-shaping pole piece on each of the poles have configurations to sculpt fringing magnetic flux in the longitudinal space so that magnetic flux density in the longitudinal space varies substantially linearly along a line in the longitudinal space between the confronting poles of the magnets. A  magnetic field sensor assembly has a housing for mounting to the other of the first and second elements. A magnetic flux sensor is mounted to the sensor housing on the line in the longitudinal space between the first and second magnets. In one embodiment, each of the flux-shaping pole pieces has a pentagon shape in a plane of primary flux pattern, forming a narrow face confronting the longitudinal space between the first and second magnets. The narrow face of each flux-shaping pole piece is wider across the primary flux pattern than along the length of the line in the longitudinal space.

Title: Integral inertial particle separator for radial inlet gas turbine engine
Inventor: STOTEN MICHAEL D
IPC: F02C7/052
Filed: 1999-05-27
Abstract: The invention provides an integral inertial particle separator in the form of a bifurcated radial intake for a gas turbine engine. Radial intake engines include an arcuate intake duct which draws in air radially from an external plenum and redirects the air flow axially into an annular compressor duct. By modifying the radial intake duct to include a bypass duct, an integral inertial particle separator is economically provided within the engine to remove sand, ice flakes and other damaging particles from the intake air flow.  The radial intake departs from convention with a discontinuous concave forward surface extending between a forward edge of the inlet and the inner compressor duct wall. The concave forward surface forces air flow into an arcuate path thereby separating relatively heavy particles from the air flow under centrifugal force. The discontinuity in the radial intake concave forward surface includes a bypass duct downstream of the inlet and a cusp shaped flow separator downstream of the bypass duct, for diverting a bypass air flow into the bypass duct.

Title: System and method of quantifying the degree of balance between the forward link and the reverse link channels
Inventor: SHAH ALI R
IPC: H04B17/00
Filed: 1999-06-11
Abstract: A telecommunication system and method is disclosed for analyzing the speech quality, e.g., the Bit Error Rate (BER), on the forward and reverse links to determine whether the links are balanced. For a target cell, the BER on the forward and reverse links can first be measured. The determination of whether the links in the target cell are balanced depends upon whether the BER  percentage is known or only the BER class information is available. If the BER  percentage is known, the relative difference of the mean BER on the reverse and forward links can be compared to determine the degree of the balance.  However, if only the BER class is available, the relative distribution of occurrences of the BER classes on the reverse and forward links can be analyzed to determine whether the links are balanced. The analysis of the path balance can also be used to benchmark speech quality balance in cellular systems.

IPC: F24F13/24
Filed: 1999-05-26
Abstract: A compact air handling system (10) includes an inlet channel (24) which defines an inlet flow path in a first direction along a flow axis and a discharge channel (42) which defines a discharge flow path in a second direction, opposite to the first direction along the flow axis. Air enters the air handling system through an inlet port (12) and is discharged via a discharge port (14). The inlet channel is provided with acoustical buffering to attenuate inlet noise. The discharge channel is also provided with acoustical buffering in the form of a discharge silencer (40) to attenuate noise in the discharge channel. An acoustical inlet plenum (26) couples the inlet channel to the discharge channel. The cross-sectional area of the discharge channel adjacent the discharge port is larger than the cross-sectional area of the discharge channel adjacent the acoustical inlet plenum. if the inlet ports are not substantially equally distributed about the air handling system, a transfer passage (22) can be provided between the inlet ports and the inlet channel to provide equalization of the air flow.
