Patent CA-2214602-C (CA)
Title: Flap wheel
Inventor: EMERSON GRAHAME W
IPC: B24D13/04
Filed: 1997-08-29
Granted: 2001-05-22
Abstract: In one embodiment, a support member on an abrasive wheel has (a) an annular surface which fixedly supports (as by epoxy) a plurality of flaps in a partially overlapping relationship between successive flaps and (b) a central hole for receiving a mandrel which rotates the wheel.  Each flap has on one of its surfaces abrasive particles facing outwardly from the annular surface.          Each flap defines an acute angle with the annular surface and preferably extends at its opposite axial ends beyond the axial positions of support by such support surface to obtain a fixed positioning of the flaps relative to the support surface even at the axial positions beyond the axial ends of such annular surface.  In a second embodiment, the flaps are disposed on the annular support surface in a tighter relationship than in the first embodiment so that each flap contacts adjacent flaps along a portion of its length.  When the wheel is rotated with the flaps disposed adjacent a workpiece, the inner portions of the flaps provide an abrading action, partly because of their contact with one another, and the outer portions of the flaps provide a polishing action, partly because of their separation from one another.  This polishing action is facilitated by the fact that (a) the flaps become separated from one another at their outer ends because of centrifugal action and (b) the grit on the flaps becomes progressively worn with progressive positions toward the outer ends of the flaps.

Abstract: An apparatus and method for more accurately determining the position of a moving object by using an azimuth detector distinct from an angular speed detector to correct the gain error and the offset error of the angular speed detector. The position of the moving body is determined using the offset error- and gain error-corrected angular speed. The correction of the offset error includes checking the azimuth and movement of the moving object for three predetermined periods of time; then checking whether the moving object was moving in a straight line each of the three predetermined periods of time. If the object was moving in a straight line each of the three predetermined periods of time, then an offset error correction value is computed using data from the second of the three predetermined periods of time. The correction of the gain error includes determining the movement of the moving object as straight; then determining the movement of the moving object as a turn; then determining the movement of the moving object as straight again. If the turn was a left turn, a left gain error correction value is computed. Similarly, if the turn was a right turn, a right gain error correction value is computed.

Title: Universal, energy-absorbent trailer hitch
Inventor: GULLICKSON RUSSELL C
IPC: B60D1/50
Filed: 1997-12-15
Granted: 2001-04-24
Abstract: The present invention features an energy-absorbent, hitching mechanism for towing trailers and other vehicles by pickup trucks or other tow vehicles. This is a mechanism of the universal type, in which energy absorption is achieved for all transverse and orthogonal forces, including force vectors in the vertical, lateral and longitudinal axes, i.e., the X, Y and Z axes of movement. The hitching mechanism has a housing for receiving a hitch ball that is attached to a tow vehicle. The ball is free to move within a chamber of the housing, subject to cushion forces described below, in any orthogonal direction, i.e., along the X, Y and/or Z axes. The housing chamber contains an energy-absorbent, dome-shaped pad that cushions the hitch ball. When the ball presses against the pad from any direction, the energy of any transverse force is absorbed by the pad, which expands into at least part of the housing chamber. A slide bar that is supported by the housing engages the neck portion of the ball, anchoring the ball for movement within the padded housing chamber. The slide bar is locked against slidable movement by a spring-biased locking pin, with the spring-biasing forcing the pin to seat within a detent hole in the housing, after it has passed through the slide bar. The locking pin is pulled upward against the biasing to release the slide bar, which in turn can be slid outwardly to release the shank of the hitch ball.

Abstract: Un procédé et un appareil permettent d'utiliser efficacement à la fois la puissance et la largeur de bande d'un système (102) de communications cellulaires dans lequel une unité mobile entre préférablement en mode veille lorsqu'aucune communication ne se produit entre cette unité et la station de base pendant une période prédéterminée mesurée par un temporisateur (601) d'inactivité. Lors de la cessation de validité du temporisateur (601) de veille, l'unité mobile sort du mode veille (603) pour déterminer si un message est en instance (606). De la même manière, la station de base transmet un message de notification TEI (identification temporaire du matériel) à toutes les unités mobiles afin d'informer chacune d'entre elles qu'un message est en instance. En sortant du mode veille pour recevoir les messages, l'unité mobile détermine la qualité de la transmission (608). Si celle-ci est suffisante (610) et que le message de notification TEI n'indique pas de données en instance, l'unité mobile retourne en mode veille (601), même si elle se situe dans une cellule autre que celle associée à la station de base actuellement assignée à cette unité mobile.

Abstract: A microprocessor controlling a shuttle shift transmission may be programmed while the gearshift lever is in neutral to preselect a forward and reverse gear into which the transmission is shifted when the gearshift lever is moved to a forward or reverse position. The microprocessor may also be programmed so that, in shifting between forward and reverse, the forward and reverse gears selected differ by a pre-programmed amount. The microprocessor may be programmed to control vehicle deceleration by selecting gears in the transmission so that the transmission and/or the vehicle engine become a load for decelerating the vehicle. In a diagnostic mode, the microprocessor executes a routine to develop a clutch calibration value which may later be used to insure uniformity of clutch operation in different vehicles, or in the same vehicle over a period of time. The normal speed ratio matching which normally takes place when shifting gears may be manually overridden by operator manipulation of the gearshift lever. The override may either terminate speed ratio matching for a particular shift, or the override may be effective for a fixed interval of time.

Abstract: A composite packer or bridge plug is disclosed. The design features substantially all nonmetallic components. The design allows the setting tool metallic components to be retrieved after the bridge plug is set. The slips contain flats with mating flats on the cones which extend to one end of the cones and guides for the slips to facilitate proper slip movement into engagement with the wellbore. A lock ring rides on the nonmetallic mandrel and secures the set, using a buttress-type thread to engage into the mandrel body. Alternative designs are revealed for backup to the sealing elements to prevent extrusion. In one design, split rings are axially compressed so that they grow in radial dimension to act as extrusion barriers. In another design, tapered scored rings are rotationally locked against each other and are axially compressed so that they bend into contact with the wellbore to act as extrusion barriers. Axial travel to obtain an extrusion barrier is minimized.  The slips are made of a cohesive component and separate from each other upon advancement with respect to the cone. Mandrels of different plugs can lock together to facilitate mill-out in multi-plug installations.
