Patent DE-2638171-A1 (DE)
Title: Magneto-hydrodynamic converter has toroidal magnetic field - causing separation by retardation of positive ions giving almost total energy conversion
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: H02K44/08
Filed: 1976-08-25
Abstract: An MHD voltage converter comprises a toroidal or toroid-like magnetic field which produces a retarding voltage causing sepn. of the plasma charges in the longitudinal direction of the plasma flow. This causes a potential difference to be produced at opposite ends of the toroid; and this voltage is used as a power source. Typically a toroidal magnetic ring comprising a core winding and ceramic plasma guide tube has current pickups at the ends of the tube. The coil may be magnetised by AC or DC; with AC excitations, an AC is produced and converter at a transformer and condenser and supplied to the grid. Sepn. takes place longitudinally and not transversely to the plasma flow. Since almost the entire mass of the plasma is concentrated in the positively charged particles, the resultant power generation is almost 100 times as large as that of a conventional MHD generator. Also the longitudinal flow produces pinch, which keeps the plasma away from the walls of the tube.

Title: Thermonuclear pump with contactless plasma guiding - utilises condenser circuit parallel to oscillator to eliminate collectors in plasma
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G21B1/00
Filed: 1977-05-10
Abstract: Plasma-side collectors are used in the Parent Patent are omitted from the generating circuit and external h.f. electrodes are used instead. In alternation with the high-frequency current (J) flowing through the metal tube, positive and negative plasma charges are pptd. internally on the conducting wall of the tube. The effect of this pptn. is to amplify the current (J) flowing through the tube and also to supply a useful current (Jh). The h.f. oscillator requires only a small power and serves merely as a pilot current source by intermittently triggering a self-exciting current (Jh) of much greater magnitude and the same frequency. The much larger current generates an intensive magnetic field for the contact-free guiding of the plasma and also when necessary supplies current to the electrical network. Used for donating and pumping a thermonuclear reaction.

Title: Wide range absorption metal sensor - has hidden detector which acts as aerial to attenuate radiation
Inventor: EBINGER KLAUS
IPC: G01V3/10
Filed: 1977-05-13
Abstract: The method of location of conductors of unknown length is based on the measurement of the absorption of electromagnetic energy from a transmitting device whose frequency is varied over a wide range. Electromagnetic radiation from a wide-range frequency wobbler is transmitted by means of a conventional dipole aerial or coil. This antenna scans the region in which the conductor is located and the radiation is damped when its frequency coincides with the resonant frequency of the unknown conductor. The magnitude of the damping provides an indication of the dia. and the position of the antenna serves for location purposes. The method may be used to defuse parcel bombs or locate cables buried in buildings.
