Abstract: The invention relates to a method for representing the lactic acid distribution in a layer. In this method, first and second sequences with in each case at least three high-frequency pulses are generated, the first sequence being formed in such a manner that the resultant stimulated echo signal remains unaffected by the lactic acid components whereas the second sequence is formed in such a manner that the stimulated echo signal is (also) determined by the lactic acid component. By subtracting the two stimulated echo signals and repeating these sequences with coding gradients varying in accordance with size and/or set-up, a set of difference signals can be generated from which the desired distribution can be determined by two-dimensional Fourier transform. …<IMAGE>…

Abstract: A device for applying torque to e.g. a screw-threaded pipe includes a pair of gripping jaws (24) pivotally mounted on a cage (16) and carrying respective followers (27) engaging cam surfaces (28) on the radially inner surface of a rotary drive member. The jaws have friction linings (29). The cage is connected to a clamp on the pipe so as to prevent rotation of the cage relative to the pipe. When a rotary drive is transmitted to the drive member, its cam surfaces operate the gripping jaws to clamp them about the pipe and increases the clamping pressure until the pipe begins to rotate with the drive member. The rotary drive member is mounted on a primary support which is held against rotation about the pipe and provides the required reaction force for the rotation.
