Patent CA-2429459-A1 (CA)
Title: Adjustable stabiliser for directional drilling
Inventor: RUSSELL MARK ALEXANDER
IPC: E21B23/00
Filed: 2001-11-15
Abstract: A stabiliser (10) has a body (12) having a through-bore (16). A mandrel (14), also having a through-bore (20), is axially slidable in the body bore to actuate and de-actuate the tool. A step (64) in the body defines annular chambers (102, 104) between the mandrel and body on either side of the step. A control piston (18) in the mandrel alternately directs drilling mud pumped under pressure along said body bore and mandrel bore to the chambers to drive the mandrel hydraulically to actuate and de-actuate the tool. The control piston has a through-bore (46) and is slidable in the mandrel bore against the force of a return spring (40) by drilling mud pressure from a low-pressure position to a pressure position. The pressure position is alternately one of an actuate position (a) and a de-actuate position (b), axially spaced along the mandrel bore from said actuate position.

Abstract: A method for determining locations and gain settings of amplifiers in an optical network is provided. The method comprises evaluating allowable amplifier locations, randomly generating sets of amplifier locations from the allowable amplifier locations, and applying genetic operations to the sets of amplifier locations until a predetermined exit condition is satisfied. This systematic method is applicable to a variety of network topologies and takes into account existing network limitations. In one embodiment, the method for determning the locations and gain settings of the amplifiers uses the amount of operating margin in the network to select sets of locations to be eliminated. In another embodiment, the method takes into account and determines the placement of dispersion compensation modules (DCMs), choices of which are provided by DCM placement procedures.

Title: Accessory attachment system for vehicle interiors
Inventor: DEL POZO ABEJON RUBEN
IPC: B60R21/20
Filed: 2001-10-15
Abstract: The invention relates to a fixing system comprising a metal part having a base (1) that is provided with a central opening in which a screw (9) is inserted, said screw being used to fix an accessory (10) and a piece of upholstery (11) to one such fastener. The aforementioned accessory and upholstery assembly is fixed to the corresponding panel of the vehicle body by inserting said fastener into the opening provided for this purpose on the panel (8). The fastener is provided with lateral, flexible wings (5) which are bent at the lower, free edge thereof and which terminate in flanges (7) that project outwards away from one another, thereby forming the means of fixing the fastener to the opening in the panel (8). Once the aforementioned wings (5) have been inserted in the opening and the accessory (10) and upholstery (11) have been fixed to the base (1) of the fastener, said components all remain fixed to the vehicle body. Moreover, once the screw (9) and the accessory (10) have been removed, the flanges (7), which extend below the plane of the panel (8), enable the removal of the fastener. For this purpose, a standard tool is used to bend the wings (5) and the fastener is subsequently removed from the vehicle body.

Patent CA-2444933-A1 (CA)
Title: Tolerance compensating mounting device
Inventor: KNIGHT BRIAN RUSSELL
IPC: F16B29/00
Filed: 2001-09-12
Abstract: The invention comprises a tolerance compensating mounting device comprising a bushing having an internal and external thread. The bushing (101) is threaded into a part to be mounted to a surface. A bolt (200) is then threaded into a bushing bore using the internal threads. The internal threads (102) cause an interference fit between the bolt (200) shank and the threads, temporarily preventing further insertion of the bolt (200). The bolt (200) is then turned further, thereby turning the bushing (101) and causing the bushing to unscrew from the part toward the mounting surface until the bushing seats on the mounting surface, thereby completely compensating for a tolerance gap. As the bolt is turned further, at a relatively low torque the sacrificial internal threads are stripped allowing the bolt to be fully torqued into the mounting surface hole, thereby simultaneously connecting the components with a properly torqued connection while compensating for a tolerance gap.
