Abstract: A method is disclosed for determining a rock strength of an Earth formation, including: receiving a signal representing a measured variation of velocities or slownesses as function of radius from and azimuth around a borehole; generating predictions from a Mechanical Earth Model (MEM) representing predictions of a variation of stress and hence velocity as a function of distance from, and azimuth around, the borehole, the MEM including a rock strength model adapted for generating a further prediction representing a predicted variation of velocities or slowness; changing the rock strength in the rock strength model of the Mechanical Earth Model until the further prediction substantially matches the measured variation in velocity around and from the borehole; and generating a set of parameters, wherein the parameters are used to populate the MEM and are used in subsequent calculations.

Abstract: The present invention includes a communications system to measure and transmit date from a zone of interest below a downhole assembly to a remote location. The communications system preferably includes a sensor gauge engaged through a communications port of the downhole assembly upon a communications cable whereby the communications cable and sensor gauge have substantially the same outer profile diameter.

Abstract: An apparatus for forming a winding for a stator of a dynamoelectric machine comprises a form (3) and a rotating unit (11) for winding a wire (W) around the form (3). The form (3) comprises two form sections (4) which are movable toward and away from each other along a direction orthogonal to the form axis (5). The apparatus further comprises motorized means (37b, 34, 32) for controlling the relative movement of said form sections (4), which can be activated even while the winding unit (11) is being rotated.
