Patent DE-2643664-A1 (DE)
Title: Detecting material of different magnetic susceptibility - esp. nuclear fuel dope, by resultant change in magnetic field along fuel rod
Inventor: VOIGT HANS DR
IPC: G01N27/72
Filed: 1976-09-28
Abstract: A method of detecting substances in a body in which the basic material has a different magnetic susceptibility from the substance material and is partially doped with these substances consists of subjecting the material to an external magnetic field. Measurements are taken of the change in the magnetic field along the length of the body produced by magnetising of the basic material and the substances. The body may be moved along a stationary magnetic field, or vice versa. Used esp. for pelletised uranium oxide fuel in long fuel rods. The method detects and locates of doped pellets, i.e. those contg. gadolinium oxide or the like which must only be used in certain regions of the reactor.

Title: Convex disc closure for cylindrical pipe - provides radial expansion under fluid pressure in order to seal disc knife edge against wall
Inventor: WINTER KLAUS
IPC: F16J13/00
Filed: 1977-10-04
Abstract: A circular disc (1) is located inside a cylindrical hole (9) by a light interference between the hole and the tapered edge (3) on the disc. The disc has a convex curvature (2) which is opposite to the knife edge (4) on the disc edge. When the convex surface of the disc is pressuresed by a fluid, it tends to be deflected to make it flatter.
