Patent DE-3615652-A1 (DE)
Title: Inductive detector (locator)
Inventor: FOERSTER FRIEDRICH DR PHIL
IPC: H03K17/95
Filed: 1986-05-09
Abstract: A description is given of an inductive detector with the aid of which, in addition to locating electrically conductive and/or ferromagnetic bodies (12), it is also possible to determine the depth (a) at which they lie below the hunting probe arrangement (14). By contrast with already known detectors of this type, in which the relationship between the signal voltages of two exploring coils spaced apart in the axial direction is determined, use is made here of exploring coils (18, 20) which lie together in one plane but must comprise areas of different size. <IMAGE>

Title: Process for preparing magnesium oxide and/or its hydration products
Inventor: ZIKMUND MIROSLAV DR ING
IPC: C01F11/18
Filed: 1986-06-13
Abstract: A process for preparing magnesium oxide and/or its hydration products from predominantly magnesium- and/or magnesium/calcium-containing raw materials, in general with simultaneous preparation of calcium carbonate in a purity of over 99% by weight of CaCO3 is proposed. The starting material, optionally present as carbonate, is thermally decomposed. Calcium oxide and/or its hydration products are selectively extracted at a temperature of from 0 to 100 DEG C with a solution which contains at least one organic, optionally nitrogen-containing, base and at least one salt of these bases with an organic and/or inorganic acid in a total amount which corresponds to the desired degree of extraction of the calcium-containing component from the, optionally roasted, starting material. The residual magnesium oxide and/or its hydration products, optionally with impurities, are separated off from the solution and the calcium carbonate is precipitated at a pH of from 7 to 12 with carbon dioxide and/or ammonium carbonate.

Title: Nuclear reactor with a core removably assembled from individual fuel assemblies, and with a liquid coolant
Inventor: STROBEL REINHARDT DIPL ING
IPC: G21C5/06
Filed: 1987-08-26
Abstract: In such nuclear reactors, the liquid coolant usually flows upwards through the core that is assembled from fuel assemblies (7). The fuel assemblies (7) are fixed into a lower grid plate (1) by a bottom fitting (5), and into an upper grid plate by a top fitting. According to the invention, the individual fuel assemblies (7) are pressed upwards by helical compression springs (12), and pressed mechanically rigidly against the upper grid plate from below; the helical compression springs (12) are supported below by the lower grid plate (1). The buoyancy forces acting on the fuel assemblies (7) are transmitted directly to the upper grid plate by this arrangement. Therefore, the arrangement according to the invention is especially suitable for reactors in which large pressure differences occur in the coolant, such as in high-conversion rate pressurised-water reactors or breeder reactors. <IMAGE>

Inventor: RAHNENFUEHRER ECKHARD DIPL PHY
IPC: F42B5/38
Filed: 1987-11-06
Abstract: In the case of known cartouches, the direction of axial insertion of sub-cartouches is determined during manual loading by a multiple connector which does not allow the cartouches to be inserted one behind the other in any desired direction or the assembled cartouches to be loaded in any desired direction. This multiple connector can therefore not be used, to reduce the manual loading time, with identical rotationally symmetrical and axially symmetrical propellant charge modules, if these modules are to be assembled in any desired sequence, number, direction of insertion and direction of loading during manual loading. This problem is resolved by a multiple connector (1) for at least two identical rotationally symmetrical and axially symmetrical propellant charge modules (2), which have a constricted case region (5) on other side of the container (4), two adjacent containers (4) being connected on the side of the region of the casing (5) in mutual contact by a separate connector ring (6). The connector ring, in particular by virtue of an additional connection by clamping or adhesion, guarantees a high stability of the propellant charge modules which can be interconnected as desired in various graduations corresponding to their range.

Abstract: In picture tubes having an extremely flat screen, geometric distortions, which are peculiar to this type of screen, in the form of bent lines at its start and its end are apparent, caused by the magnetic deflection field specific for these tubes, the bends being located symmetrically with respect to the centre line. 
<??>This effect known by the term "bending error" is eliminated by the fact that 5-10 microseconds before the horizontal forward trace of the electron beams is ended, a current rising up to the beginning of the horizontal retrace is generated and at the end of the horizontal retrace a falling additional current lasting for 5-10 microseconds is generated and coupled into the vertical deflection winding.

Title: Process for the preparation of 1-carbamoyl-3-methylpyrazole
Inventor: JOEDICKE REINHARD
IPC: C07D521/00
Filed: 1988-05-09
Abstract: The invention relates to a process for the preparation of 1-carbamoyl-3-methylpyrazole (CMP) from the reactants 3(5)-methylpyrazole (MP) and alkali metal cyanate in the presence of acid. CMP is an effective agent for inhibiting the nitrification of ammonium nitrogen in cultivated soils. The reaction is not carried out, as usual, in the acidic range, but in a pH range of 10-7. This gives CMP suspensions which have very good filtering properties and high CMP yields. The alkali metal salt of the acid used, which is formed as a by-product, is separated off or coprecipitated together with the CMP and dried.
