Abstract: Trans-N,N-dimethyl-9-[3-(4-methyl-1-piperazinyl)propylidene]-thioxanth ene-2-sulfonamide is isomerized to the cis-isomer by contacting the trans-isomer with strong base in a polar organic solvent. By using an organic solvent in which the solubility of the cis-isomer is substantially less than that of the trans-isomer, the cis-isomer can be selectively precipitated from said solvent, thereby favoring additional isomerization to the cis-isomer in the supernatant, and separated.

Abstract: In the case of very large pipe turbine units, an additional vibration-stable base for transmitting vertical and horizontal forces is produced, normal to the machine axis, in addition to the normal anchorage on the turbine tube housing for the generator and coupling part. The unit consists of a cupola (1) on the upstream side, the generator stator (2) and the turbine tube housing (3). On its own, the turbine tube housing (3), which is supported in the foundation (10), cannot, however, transmit all the further forces, in addition to the total axially directed forces, which act in the region of the cupola (1) and of the stator (2), such as the weight load, lift, torque and horizontal side forces of a static and dynamic type, to the structural body. In particular, vibration safety is not ensured. The additional support is provided via the feet (4) onto the bases (5) of the foundation (10), the respective contact surface being designated by (6) and (7) respectively. Contact surfaces (9) are provided between the bases (5) and the feet (4) in order to absorb horizontal forces, normal to the axis direction of the unit. Anchorage is effected by means of the screws (8) which are tightened with adjustable prestresses. <IMAGE>

Abstract: A plug (4') for injecting fluid into rock formations or the like structures comprises a tubular body (1) with a one-way valve (3) in one end thereof and an annular sealing member (2) of flexible material, capable of limited axial movement, surrounding the tubular body (1). The sealing member (2) includes a lip or flange (6') for initial sealing and retention of the plug. When inserting the plug (4') into a borehole the flange (6') folds down and thus permits insertion of the plug. At the desired location for the plug. the tubular body (1) is pulled backwards somewhat and this causes the flange (6') to double back on itself so that the flange lies on the outside of the main body of the sealing member (2) and constitutes an initial sealing and retention of the plug (4'). Furthermore there is wedging engagement between the external surface of the tubular body (1) and the internal surface of the sealing member (2) causing radial expansion of the latter when the tubular body (1) is moved rearwardly. Upon introduction of an injection fluid through the plug and the valve (3), an over-pressure arises in the borehole and the tubular body moves further backwards and further increases the radial expansion of the sealing member (2) by said wedging engagement for final sealing and plugging of the injection hole. <IMAGE>
