Title: Method of reducing the resistance during the forcing of pipes into the foundation soil and during the drilling and holing-through of earth
Inventor: SCHMIDT JOHANNES PROF DR SC TE
IPC: E02D7/20
Filed: 1989-03-23
Abstract: The invention relates to the reduction of the penetration resistance during the forcing of pipes into the foundation soil and during the drilling and holing-through of earth, in which one or more anodes are placed in the working direction at a lateral distance from the pipe to be forced in, the bore or the intersection, these anodes are connected to the positive pole of a direct-current source, and the pipe to be forced in or the drilling or holing-through tool, which have the function of a cathode, are attached to the negative pole of the direct-current source. Upon contact with the earth, an electric field forms between the anodes and the pipe or the drilling or holing-through tool. The electric field results in a movement of the water contained in the earth in the direction of the cathode, in the course of which a water film forms on the skin surfaces in front of the pipe or the drilling or holing-through tool and after the start of the penetration into the earth, and the point resistance or the skin friction is reduced in the earth zone with increased water content.

Inventor: KIMMICH RAINER PROF DR
IPC: G01R33/483
Filed: 1989-06-10
Abstract: In a nuclear magnetic resonance system, the signal acquisition period is chosen in relation to the spin locking period of the magnetising. This allows the formation or influence of picture contrast or characteristic resonance by :- (a) one of the two variables of the rotating coordinates of the spin lattice relaxation time; (b) the frequency dependance of one of these two variables. (c) The susceptability dependance of one of these two variables. Pref the spin locking is at or near resonance where the effective magnetic field is aligned with the magnetising to be locked or, off resonance to reduce power demand for the high frequency RF field but allow missalignment of the effective field from the field to be locked. USE/ADVANTAGE - In nuclear magnetic resonance based tomography, localised relaxometry and localised spectroscopy.  Previously inaccessible material characteristics can be identified.  When contrast intensifiers are used the doses can be considerably reduced. Information can be taken as contrast or volume selection data measurements. No additional measurements are necessary in normal areas.
