Patent CA-2237022-A1 (CA)
Inventor: ROSENTHAL DIETER
IPC: B21B37/40
Filed: 1998-05-07
Abstract: A method of influencing the strip contour in the edge region of a rolled strip in which by superimposing a conventional CVC contour the harmful side effect of a unilaterally narrowing roll on the body portion of the roll gap is compensated.  Special CVC rolls are used as work rolls for influencing the strip contour in the edge areas.  The special CVC roll for influencing the strip contour in the edge area is a roll with a profile, which, starting from a tapered end, has the steadily changing diameter differences of a continuously variable crown, which, in accordance with the invention, is profiled in axial direction in such a way that during its axial displacement the resulting undesirable component of the effect of the conical taper, i.e., the change of the elastic behavior of the roll set, is compensated, wherein this occurs especially to such an extent that additional conventional adjusting measures, such as redistribution of the rolling force or roll bending, are sufficient for maintaining the desired geometry of the roll gap over a wide range of a rolling schedule.

Title: One-trip, thru-tubing, window-milling system
Inventor: LUEDERS EDGAR D
IPC: E21B7/06
Filed: 1998-06-30
Abstract: A one-trip, window-milling system method and apparatus is disclosed. The system is particularly useful in thru-tubing applications where the mills are run on coiled tubing in conjunction with a downhole motor. Preferably, the whipstock is run through tubing and set in position. The mill assembly is typically run in after the thru-tubing whipstock is oriented and set. The mill assembly is supported by a downhole motor, which is in turn run-in with coiled tubing. The pilot mill or leading mill is of a particular shape so as to minimize its torque requirements for initiating the window. A wear device, which acts as a guide, is located behind the initial mill and acts with a flexible connector above the subsequent mills in orienting the initial mill into the casing and away from the whipstock. The subsequent mill or mills feature a gradual increase in cross-sectional area along its or their length, also minimizing the required torque for the downhole motor. The system is capable of penetrating thick casing such as standard weight 7" casing in approximately 3 hours or less.

Abstract: The invention relates particularly to sensing devices and techniques which may be used to provide measurement data to aid an inertial navigation system, or attitude and heading reference system, and so bound the growth of errors which increase with time in such systems when operating autonomously. In one aspect, the invention relates to a method of determining the path length along a borehole from a known reference point to a probe or tool which progresses through a drillpipe or tubular string, to provide data to aid an inertial navigation system. A sensing device 15 is used to detect joints 11 between sections of drillpipe or tubular string within the borehole and the path length is determined from the number of joints detected and a known length of each section of drillpipe or tubular string. In another aspect, a flow measuring device, such as an impeller, is used to measure the velocity of the probe or tool through the drillpipe or tubular string. In another aspect the invention relates to a method of determining the velocity of a probe or a tool moving through a drillpipe or tubular string to provide data to aid an inertial navigation system. Two sensing devices, which are spaced apart by a known distance on the probe or tool, are used to detect one or more positions within a drillpipe or tubular string, and the velocity of the probe or tool is determined from the elapsed time between each sensor detection of the or each position and the distance between the sensors.

Abstract: A variable length telescoping viewfinder for cameras that provides a variably adjustable eye viewing distance relative to the camera without changing the focus or magnification of the scene being photographed throughout the telescoping movement of the viewfinder. The light rays of the real image supplied to the viewfinder directly or indirectly from the camera are passed through a field lens, Pechan prism, relay lens system forming collimated light rays from the fixed front module to the movable rear module wherein lens elements form an intermediate image that is viewed through an eyepiece lens group. The front module is weakly powered and of a substantial effective optical length because of the inclusion of the Pechan prism. The image forming lens group of the rear module is weakly powered whereby relative telescopic movement between the front and rear modules does not adversely affect the location, focus or magnification of the intermediate image throughout the range of movement. A magnification lens group is provided for selectively magnifying the intermediate image by moving the magnification lens group into and off the optical axis. The Pechan prism also allows proper orientation of the image. The eyepiece lens group for viewing the intermediate image may include a movable lens subgroup for precise focusing to compensate for far-sightedness or near- sightedness of the human eye.
