Patent CA-2170711-A1 (CA)
Title: Locator and setting tool and methods of use thereof
Inventor: GAZDA IMRE I
IPC: E21B47/09
Filed: 1996-02-29
Abstract: An electrically powered locator and setting tool is described which is capable of locating and then setting a barrier member within a cased wellbore or other string of tubular members in a manner such that the barrier member will not be set at a casing joint. The locator and setting tool preferably features a single tool arrangement containing a casing collar locator and a packer setting assembly. The casing collar locator includes a detection means which detects the actual locations of casing collars along the casing string. The locator then provides a signal indicative of these locations. The setting tool includes a motor and an associated linear drive section which will operate an attached retrievable packer assembly to set the packer assembly at a desired point in the wellbore. A remote power source, usually located at the surface of the wellbore, supplies electrical energy to the locator and setting tool through an electrically conductive power line which can be extended down through the wellbore. Because the locator and setting tool is preferably run into a wellbore by wireline, the power line is typically disposed along or within the wireline running arrangement. In methods of operation described herein, a planned setting point within a cased wellbore is established based upon recorded well logs and customer requirements. The planned setting point is established at a point in the casing string where no joint is recorded. A packer assembly is disposed into a wellbore using the locator and setting tool to a point proximate the planned setting point according to physical measurement of the running arrangement via manipulation of the locations of casing collars around the planned setting point are detected by the casing collar locator. The detected depths of the casing collars are then compared to the recorded collar depths if the detected and recorded depths match, the packer assembly may be set at the planned setting point. If there is a discrepancy between the detected and recorded collar depths, the customer can be informed and warned that setting the packer at the planned setting point may result in setting at a joint. The adjusted setting point is located in a portion of the wellbore where no casing joint is located which could prevent the barrier member from establishing or maintaining a fluid seal when set. According to the methods herein described, the locator and setting tool is removably affixed to a retrievable packer assembly. The "offset distance," the approximate longitudinal distance from the casing collar locator's detection means and the sealing member of the packer assembly, is measured. A running arrangement and a power line are attached to the locator and setting tool. Once the setting point has been adjusted and verified as described, the locator and setting tool and affixed packer assembly are disposed within the wellbore to the depth of the adjusted setting point. The packer assembly may then be set inside the wellbore by operation of the packer setting assembly .

Inventor: ZEITER PATRIK
IPC: B29C51/08
Filed: 1996-02-29
Abstract: Device for manufacturing cold-formed shaped forms of packaging out of a metal-plastic laminate where the said device contains a die with at least one die opening, in the die opening a stamp which may be driven by the die, and a retaining tool as a clamping facility that holds the laminate securely between the die and the clamping facility. The die and the retaining tool feature a facing edge region and the die, within the edge region, a shoulder region that surrounds the die opening, and the surface of the shoulder region lies 0.01 to 10 mm lower than the surface of the edge region of the die. Parts or in particular the whole of the shoulder region may be covered with a surface layer of low friction characteristics. The metal-plastic laminate is held clamped between the edge of the die and the edge of the retaining tool, and the stamp draws and stretches the part of the laminate in the region of the shoulder over the shoulder into the die opening.

Abstract: An exercise device includes a frame which supports a pair of foot links so that a first end of each foot link is pivotably coupled to the frame for motion about an arcuate path. A guide which is supported by the frame engages each foot link and directs a second end of each foot link along a closed, curved, generally teardrop shaped path of travel. This combination of motions defined by the foot link provides a natural running and stepping motion in which the heel of a user's foot initially rises faster than the toe as the foot move begins to forward and subsequently falls faster than the toe as the foot begins to move backward.

Abstract: The invention is a process for simultaneously improving at least two mechanical properties of mill-processed (.alpha. + .beta.) titanium alloy, which may or may not contain silicon, which includes steps of heat treating the mill-processed titanium alloy such that the (.alpha. + .beta.) microstructure of said alloy is transformed into an (.alpha. + .alpha.2 + .beta.) microstructure, preferably containing no silicides. The heat treating steps involve subjecting the mill-processed titanium alloy to a sequence of thermomechanical process steps, and the mechanical properties which are simultaneously improved include (a) tensile strength at room, cryogenic, and elevated temperatures; (b) fracture toughness; (c) creep resistance; (d) elastic stiffness; (e) thermal stability; (f) hydrogen embrittlement resistance; (g) fatigue; and (h) cryogenic temperature embrittlement resistance. As a consequence of the process, the (.alpha. + .alpha.2 + .beta.) microstructure contains equiaxed alpha phase strengthened with .alpha.2 precipitates coexisting with lamellar alpha-beta phase, where the .alpha.2 precipitates are confined totally to the equiaxed primary alpha phase. The invention also encompasses a composition of matter produced by the inventive process, especially one comprising a titanium alloy having an (.alpha. + .alpha.2 + .beta.) microstructure.
