    • The invention relates to processes for the microbial production of L-isoleucine. To this end, in a gene in vitro of a threonine dehydratase, one or more bases in the gene region coding the enzyme's allosteric domains is/are exchanged in such a way that at least one amino acid in the amino acid sequence of the allosteric domains of the enzyme is replaced by another so that the enzyme is no longer inhibited by L-isoleucine feedback. Furthermore, concrete amino acid exchanges in the amino acid sequence of the enzyme are effected in a gene in vitro of a threonine dehydratase of corynebacterium glutamicum by base exchange both outside and inside and outside the gene region coding the allosteric domains of the enzyme so that, after the transformation of such mutated threonine de hydratase genes into a threonine or L-isoleucine-producing host cell, the latter repeatedly forms L-isoleucine.

    • Ionisable or polarisable, carrier-free radionuclides may be separated by electrofixation, in a manner that is particularly well adapted to practical requirements, from a low electric conductivity liquid target material in a flow cell (1) fitted with a permanent electrode arrangement (2, 3). For that purpose, the target liquid is separated while the fixing voltage is maintained, then the fixed radionuclide is removed again from the electrode, if required by heating, after switching off or reversing the poles of the field, possibly after an intermediate rinsing. A cylindrical fixing electrode that forms the vessel casing with an axial counter-electrode shaped as capillaries that extend over the whole length of the cylinder and that at the same time supply the liquid medium are particularly appropriate. Field intensities in a range from 10 to 100 V/cm are appropriate. The flow cell may be integrated in the duct that extends from the nuclide generating station to the radiotracer synthesising apparatus, may form parts thereof or may be constituted by the reaction vessel of the synthesising apparatus. The apparatus is specially designed to extract F from H2 O.

    • The invention relates to a spinning device with a take-up spool (1) for the thread (5) secured to a rotary spindle (1). The thread (5) is taken by a centrically arranged guide (6) and taken inside a free-floating rotation-symmetrical component (3) to a second thread guide (4) rotating therewith. From there it is taken to the spool (2) and wound thereon during the relative movement between the spool (2) and the component (3). According to the invention, the rotation-symmetrical component (3) is tubular. Its section surrounding the spool (2) is supported by a radially active and axially passive magnetic bearing (9) and at the face towards the oncoming thread by a radially stable and axially unstable magnetic bearing (12, 13, 14). In addition, there are sensors (23) to detect the axial deviations of the component (3) from its reference position as a measure of the changing tension on the thread, downstream of which there is an electronic device (25).

    • A recording system with magneto-optic layers has a magnetic layer for recording digital information. The recording system has two or three ferromagnetic layers with intermediate semiconducting layers. The ferromagnetic layers are magnetised with different degrees of hardness. The thickness and band gap of the semiconducting layers are sized so that a sufficient number of electrons capable of being excited by photo-induction may be excited in the hitherto empty conduction band states of the semiconductor by a focused beam emitted by a source of light of appropriate intensity and wavelength. An RKKY-type coupling is thus created between adjacent ferromagnetic layers which would not exist in the absence of light. This coupling causes information to be recorded in or erased from one of the ferromagnetic layers. Also disclosed is a magneto-optic recording system with recording layers and writing head, light source and focusing system. This recording system makes a particularly rapid writing process possible.

    • The invention relates to an electrode-electrolyte unit for a fuel cell, especially a direct methanol fuel cell comprising a barrier layer between two electrolyte layers. Said barrier layer enables transmission of protons but prevents the transfer of additional substances, especially methanol, to the side of the cathode. Barrier layer materials in prior art are palladium-silver-alloys which are very cost-intensive or vanadium, nickel and titanium based metal hydrides. The utilisation thereof in the case of polymer membranes involves a higher risk of corrosion. The barrier layer unit (3) comprises a barrier layer (4) consisting of electroconductive carbon. When the layers are thin, the barrier layer (4) is sufficiently permeable for atomic or molecular hydrogen and is, at the same time, sufficiently permeable for additional substances, e.g. methanol or water.
