Patent CA-2427453-A1 (CA)
Inventor: MAGUIRE PATRICK G
IPC: E21B17/06
Filed: 2001-12-04
Abstract: The present invention generally provides a running tool (100) comprising a torque-dampening system. A first portion (116) and a second portion (118) of the running tool are operably related by a torsion interface (128). In one embodiment, the torsion interface includes a plurality of interlaced teeth (130A,130B) disposed on the each of the first and second portions. During relative rotation of the first and second portions, the teeth engage and "ride up" on one another, thereby forcing the first and second portions in opposite axial directions. At least one of the portions houses a flow restrictor assembly (264) adapted to restrict fluid flow from one region to another during the axial movement of the portions. Accordingly, the relative rotation between the portions is inhibited, or dampened.

Abstract: In an arrangement for determining the spectral reflectivity of a measurement object, the object of the invention is to provide a simpler and more compact measuring arrangement, to eliminate the removal of elements from the beam path for detecting the reference beam, which was formally necessary, an d to avoid complex translational and rotational movements. Different beam areas proceeding from the radiation source serve as measurement beam and reference beam which are directed simultaneously to different spectrally dispersing areas of at least one dispersive element and to different receiver areas of at least one receiver in a spectrograph. Preferred measurement objects are surfaces which reflect in a spectrally-dependent manner for radiation in the extreme ultraviolet range (EUV), but application of the arrangement is not limited to this spectral region.</ SDOAB>
