Abstract: ABSTRACT OF THE DISCLOSURE      Process and device for sealing barrier constructions in subterranean galleries, especially in salt mines. In the pro-cess, a fluid sealing medium is filled into a hollow space and is maintained at overpressure relative to the pressure of a stressing medium.  With the device, a hollow space is filled with a sealing medium,  maintained below overpressure,  and positioned between the part of the gallery to be protected and the part of the galley in which a stressing medium is present.          The sealing medium is stressed with a preset pressure and at the pressure of the stressing medium.  The hollow space has a pressure shaft, in which the sealing medium stands at a pre-determined level.   The part of which is located above the level of the sealing medium is connected with the gallery in which  the  stressing medium stands.   Through  this,  it  is ensured that a specific overpressure is always present in the hollow space.  Losses of sealing medium are independently com-pensated through the column of sealing medium in the pressure shaft, which represents a supply of pressure medium.

Abstract: ABSTRACT OF THE DISCLOSURE A sonic well logging system and apparatus for determination of seismic wave velocities from a seismic wave propagating in a subterranean formation about a well-bore.  The system includes the process of imparting a seismic wave into the subterranean formation about the wellbore, and receiving the seismic wave after it has interacted with the subterranean formation at a plurality of seismic receivers positioned in the wellbore. The seismic waves are transformed at each of the seismic receivers into a seismic signal and these signals nonlin-early stacked for a selected position in the wellbore to generate a velocity spectrum of seismic wave velocities. Coherency peaks are then selected from the velocity spectrum with each coherency peak having associated there-with a unique seismic wave velocity, such as P-wave, S-wave, tube wave and the like.

Abstract: ABSTRACT OF INVENTION           This invention relates to improved hair waving and straightening compositions of matter. The novel compositions of matter of this invention comprise a sulfite and/or bisulfite reducing system, urea, a cationic polyquaternary resin of such a nature that in combination with the urea in the reducing system a hair waving and/or straightening effect equivalent to conventional thioglycolate systems is effectuated without the attendant unpleasant odours associated with the thioglycolate systems.  In addition, the reducing system of this invention is less damaging to the hair and skin than the thioglycolate systems.  The system of course may be used either with or without heat such as heat from hair dryers.  In order to achieve the above-mentioned objective, the compositions of this invention are at a pH in the range of above 5.5 to about 8.5, preferably 6.5.  Such hair waving and straightening compositions may contain any conventional additives employed in the known sulfite and/or bisulfite (e.g. wetting agent, fragrance compounds, colouring agents, thickening agents, opacifying agents, sequestering agents, solubilizing agents, conditioning agents, etc.).  The novel hair waving and straightening compositions of this invention are used in conjunction with conventional neutralizing compositions used for conventional hair waving compositions.  As is well-known, such neutralizing compositions contain oxidizing agents capable of restoring the disulfide linkages in the hair keratin during the resetting stage.
