Patent CA-2350149-C (CA)
Inventor: TURLEY ROCKY A
IPC: E21B17/02

Abstract: An expandable packer provides a crescent-shaped cross-sectional area for more and larger diameter data cable and fluid control conduits by eccentrically offsetting the packer mandrel relative to the expandable element. The expandable element of the packer eccentrically surrounds the mandrel to provide an eccentric volume zone between the packer collars. One or more data cable or fluid carrier conduits may be laid between the collars within this eccentric zone, all of greater diameter than would be possible within an annulus between two concentric mandrels. The eccentric zone conduits are secured and protected by a compliant filler material such as rubber or other elastomer that is applied around and between the control conduits within the eccentric zone. This filler material is trimmed or cast to a substantially cylindrical surface about an axis that is substantially coextensive with the expandable element axis.

Abstract: The present invention is an improved modular chain link used for constructing a modular conveyor chain. The chain link (13) includes a plastic body (16) having a plurality of spaced link ends (25) which are adapted to interwesk with complementary link ends (25) projecting from a link or links in an adjacent row. The link ends include axially aligned openings (33) that are adapted to receive a connecting pin (17). The connecting pin (17) extends through the openings (33) in the link ends (25) of the intermeshing links and fastens the adjacent links together such that the links can pivot with respect to each other. The improved modular chain link (13) further includes a support member (74) that is molded within the plastic body of the chain link. The support member (74) increases the strength of the modular chain link and minimizes the thermal expansion and contraction that occurs when the chain link is subjected to a temperature change.

Filed: 2000-07-21
Granted: 2009-03-17
Abstract: A syringe plunger driver system capable of engaging different sized syringes.  A drive head includes a pushing surface as well as spaced-apart arms biased toward each other and toward the pushing surface. An activating lever moved to a first position moves the arms outward away from each other and forward toward the syringe barrel of ease in loading a syringe.

Abstract: A hand brake system (40) for a rail vehicle providing a hand brake position alarm (76) before a train is moved with a hand brake not fully released. A switch (56) detects the position of a hand brake drive chain (18) to provide a brake engaged signal (60). The weight of the drive chain is supported through a load path that bypasses the switch. A master controller reverser handle position detector (74) provides a reverser handle position signal (72) when the reverser handle is moved out of neutral in preparation for providing power to the locomotive drive motors (15). A relay (70) is used to actuate the multiunit wheel slip indicator (54) and the general alarm bell (52) in every locomotive of the train consist when the brake engaged signal is coincident with the master controller reverser handle position signal. This combination of alarms, which normally indicates a locked axle when the train is above a predetermined speed, is interpreted as a hand brake position alarm when the train is at rest.

Abstract: A method of determining the distribution of shales, sands and water in a reservoir including laminated shaly sands using vertical and horizontal conductivities derived from nuclear, NMR, and multi-component induction data such as from a Transverse Induction Logging Tool (TILT). From the resistivities of the sand laminate, empirical realtions are used to predict anisotropic reservoir properties of the reservoir. The TILT data are inverte d based on anisotropic assumptions about laminated shale, with bulk permeabili ty as a measurement (103) constraint; and an assumption that sand comprises a number of intrinsically isotropic layers which gives a model such as a Thoma s- Stieber and Waxman-Smits model, that comrises laminated sands including wate r and dispersed clay, laminated shales and clay-bound water is isotropic. Estimates of inverted shale volume are compared to the estimate from nuclear logs. A difference between the two estimates is an indication that the sands may be anisotropic. A check is made to see if a bulk water volume determined from the inversion is greater than a bulk irreducible water volume from NMR measurements. NMR data are then used ot obtain sand distribution in the reservoir.

Granted: 2011-10-11
Abstract: Method of confirming the establishment of a voice connection, such as a VoIP connection, between first and second end stations coupled to a packet switched communications network. The voice connection is used to transfer an audible request from the first end station to the second end station, to ask the user of the second end station to generate a predetermined vocal response. The first end station compares any response from the second end station to the predetermined vocal response. The connection is determined to be established in response to a successful comparison. The predetermined vocal response includes a predetermined speech sequence comprising characters, a word or words, and a speech recognition procedure is applied to the received response to determine the presence of any speech sequence for comparison with the predetermined sequence. If a fault is detected an alternative connection is established to execute a process to correct the fault.

Abstract: The invention concerns a device having the shape of a spiral and/or helical slot cylindrical cavity (15) for reducing induced drag, tip vortex and to increase lift-drag ratio. The device securely fixed to the wing tip (10) or securely articulated to said wing tip, can be adapted to all profiles, in particular to aeroplane wings, to gliders, to helicopter blades and to driving, pusher or propelled airscrew tips such as wind turbine blades or for craft such as boats or submarines using lift or steering in their three-axis movement, vertical, horizontal and yawing. For existing rates of efficiency, the invention enables the use of low traction systems, longer and faster trips while consuming less energy or while producing more as with wind turbines for example, the use of greater loads, the increase and approach of aerodrome or airport transit/landing/take-off traffic more safely. When used in reverse (active surface/passive surface) on high-speed land vehicles or racing cars, said device fixed to each wing tip, produces a result inversely proportional to its speed. The faster the vehicle runs the less drag it produces and the more it adheres to the ground.
