Abstract: A system for measuring desired drilling parameters of a pipe string during an oil and gas well drilling operation is provided that includes a top drive assembly; a pipe running tool engageable with the pipe string and coupled to the top drive assembly to transmit translational and rotational forces from the top drive assembly to the pipe string; and one or more measurement devices mounted to the pipe running tool for measuring the desired drilling parameters of the pipe string during the oil and gas well drilling operation.

Abstract: A pipe running tool for use in an oil drilling system and the like comprises a lower drive shaft adapted to engage a drive shaft of a top drive assembly for rotation therewith. The pipe running tool further includes a lower pipe engagement assembly which is driven to rotate by the lower drive shaft, and is designed to releasably engage a pipe segment in such a manner to substantially prevent relative rotation between the two. Thus, when the lower pipe engagement assembly is actuated to securely hold a pipe segment, the top drive assembly may be actuated to rotate the top drive output shaft, which causes the lower drive shaft and lower pipe engagement assembly to rotate, which in turn rotates the pipe segment.

Abstract: A method and a device for adjusting one or more roll segments (1) in a continuous casting installation for metals, especially for steel materials, the rolls (1a) of which adjusted in the segment upper frame (2) and the segment lower frame (3) on frame cross members (5) by pairs (4) of hydraulic piston-cylinder units in a position-and/or pressure-controlled manner, wherein an operation for guiding and/or pressing the casting strands (6) is switched from a position-controlled to a pressure-controlled operation when pressure within the respective pair (4) of piston-cylinder units reaches a predetermined maximum value, whereby an improved reaction is effected by operating the piston-cylinder unit of every roll segment (1) in the case of overload, in subsequent steps at a reduced pressure or in a pressureless switching mode until the switching mode is reached in which the segment upper frame (2) can be opened to some extent.
