Patent DE-2336790-A1 (DE)
Title: DC polarity electronic reversing switch - with bismuth or germanium elements, has elements in bridge ccts acting as variable resistors controlled by magnetic field
Inventor: THALHEIM KLAUS DIPL-ING
IPC: H03K17/90
Filed: 1973-07-19
Abstract: The d.c. polarity refersing switch has four contacts, consisting of bismuth or germanium and situated around a circle at 90 deg. intervals. The contacts are magnetically connected by a circular yoke. A permanent magnet bar rotates inside the circle so that the presence or absence of its magnetic field alters the resistance of the contacts which are electrically connected to form a Wheatstone bridge whose resistors are the variable resistances of the four contacts. The magnet poles facing two of the contacts and its neutral axis, cutting the other two, upsets the bridge balance, thus allowing current to flow pref. in one direction. Rotating the magnet through 90 deg. reverses the direction of this preferential current. Since the switch has no mechanical contacts, contacts, contact damage due to arcing is avoided.

Title: Nuclear power plant housed in rock cavities - uses rock as substitute for pressure vessel and containment
Inventor: MOSER PAUL
IPC: G21C1/32
Filed: 1974-04-26
Abstract: A nuclear power plant comprises prim. components, such as reactor, gas-turbo-generators, heat exchangers, and precoolers; all these are housed in cavities excavated from natural rock, which thus fulfils most of the functions of the sec. components, such as pressure vessel and containment structure. The space with the containment structure is replaced by a number of tunnels in the rock, which provide access from outside into the plant. Pref. the rock faces are lined with reinforced and/or prestressed concrete. Locks may be used for access through the tunnels. The longitudinal axes of the tunnels may be predominantly horizontal, or vertical. Used as e.g. helium-cooled reactor with direct circuit to gas turbines. The use of natural rock reduces the expense of prestressed concrete pressure vessels and containment vessels. Constraints on plant layout can therefore be relaxed.

Patent DE-2524052-A1 (DE)
Inventor: BRUGER PETER DR ING
IPC: H01Q1/48
Filed: 1975-05-30
Abstract: Such guys, having electrically conductive guying cables (8, 9), can influence the radio-frequency operation of the antenna (2) and must therefore be split by insulators (10, 11, 14). In consequence, guying cables can no longer dissipate electrostatic charges. It is therefore known for the insulators (10, 11, 14) to be bridged by DC bridging elements (12, 13, 15). The invention is intended to save bridging elements. This is achieved in that guying cables are less frequently split by bridging elements and the value of the radio-frequency impedance of the remaining bridging elements is dimensioned in such a manner that the radio-frequency currents which are excited on the cable elements influence the antenna operation only slightly. <IMAGE>
