Title: Method and apparatus for positioning and repositioning a plurality of service tools downhole without rotation
Inventor: MCMAHAN MICHAEL E
IPC: E21B34/12
Filed: 1999-06-09
Abstract: A method and apparatus is disclosed for downhole remediation. In the preferred embodiment, a bridge plug and service packer can be run into a well on coiled or rigid tubing. The assembly is capable of being set without rotation.     The service packer is locked against setting until it is separated from the bridge plug. Setting of the bridge plug closes a passage within it that had been open to facilitate circulation during run-in. The service packer is set with longitudinal movements using an indexing mechanism. At the conclusion of the procedure, the service packer is released and lowered to recapture the bridge plug. The bridge plug is equalized and released to allow the assembly to be repositioned elsewhere in the wellbore or retrieved. The spacing between the packer and bridge plug can be varied as desired.

Title: Straddle-type all-terrain vehicle with progressive differential
Inventor: GAGNON CLAUDE
IPC: B60K5/04
Filed: 1999-06-23
Abstract: A four-wheel drive straddle-type all-terrain vehicle has a progressive limited-slip differential that functions as an open differential when the wheel speed differential is less than a predetermined threshold, or cutting point, and functions as a progressive limited-slip differential when the wheel speed differential exceeds the cutting point. The progressive limited-slip differential is able to transfer torque to the wheel with greater traction as a generally linear function of the wheel speed differential, meaning that the more one wheel slips with respect to the other, the more torque is transferred from the slipping wheel to the wheel with traction. The progressive limited-slip differential comprises a rotary shear pump that drives a piston against a pack of clutch plates. The force of the piston against the clutch pack locks the left and right axles together to provide optimal traction in slippery conditions. Since the rotation of the pump is caused by relative wheel spin, the progressive limited-slip differential is said to be speed-sensitive in that it is responsive to wheel speed differential and exerts a locking force directly proportional to speed differential.

Patent CA-2295004-A1 (CA)
Inventor: SPANNBAUER HELMUT
IPC: F02M35/10
Filed: 1998-06-19
Abstract: The invention relates to an induction port with an optimal noise level, especially a suction pipe for use as an induction port of an internal combustion engine. The noise level is optimised by introducing shunt resonators (16, 18) in the collecting chamber (12) of the suction pipe. Said suction pipe is produced using a multi-shell technique. The inserted structures (16, 18) can be stuck or welded before the shells are joined. The inventive shunt resonators (16, 18) require little space and can also be used for subsequently optimising the suction pipes in the test phase, should the test results be acoustically unsatisfactory.
Patent CA-2295180-A1 (CA)
Inventor: SHEPARD C B JR
IPC: C23C16/44
Filed: 1998-06-22
Abstract: A gas injection disc is provided which includes an outer ring and a tubular modular insert which slips into the outer ring. The outer ring is provided with an inner bore, a ring-shaped plenum located around the inner bore, an outer gas sealing surface around the plenum, and two gas feed paths extending from the periphery of the outer ring to the plenum. The gas feed paths are each provided with a gas feed attachment for coupling gas supply tubes thereto. The insert is provided with a plurality of radially aligned injectant holes, an inner gas sealing surface, and an axial bore. The insert is seated in the inner bore of the outer ring such that the inner and outer gas sealing surface face each other with a small gap provided therebetween which enables the insertion of the insert into the inner bore. The insert thereby substantially encloses the plenum, and the injectant holes are aligned with the plenum to receive injectant gases and direct the injectant gases into the axial bore of the insert. During the CVD process, the heat generated by the arc jet causes the insert to expand and eliminate the gap between the inner and outer sealing surfaces to thereby prevent undesirable gas leakage. Once the CVD operation is stopped the insert is permitted to cool and contract and return to its cooled dimensions unencumbered by the outer ring. The insert may then be removed for cleaning or for replacement with an insert having different characteristics.
