Title: Nuclear fuel rod safety valve - for rod with closed fission gas - chamber
IPC: G21C3/17
Filed: 1970-05-13
Abstract: The central space within the fuel rod, esp. in liquid sodium cooled reactors, within which fission produced gases collect, is subdivided into a number of compartments separated by bulk heads, either of porous sintered metal or with capillary holes drilled where they are solid, which allows a controlled gas leak from the compartment in the event of sheath damage elsewhere along the sheath. By this means the rate of escape of fission gases, in the event of sheath damage, into the coolant is restricted.

Title: Direct nuclear/mechanical energy conversion - using magnetic nuclear fuel inserts in rotor/stator configuration
IPC: H02N11/00
Filed: 1971-06-09
Abstract: At least two counter rotating rotors with permanent magnet poles, even in number of either ferri- or ferro-magnetic nuclear fuel material are used and so synchronised that a complete cycle of motion is divided into twice the number of stages as there are pairs of poles, half of these stages being "push" stages in which energy is required to overcome the coulomb force energy and the other half recovery stages in which the coulomb force energy is released. By superimposing a transverse two- or poly-pole magnetic field on that of the rotating poles of the rotors, the effects of the combined fields subject various parts of the mechanical assembly to various forces which do not affect rotor motion and there is a net energy gain between the "push" and recovery stages which energy gain is taken off at an output shaft. More economical energy conversion than that involving nuclear-thermal followed by thermo-mechanical conversions.

Title: Stocking tights - with stretch yarn in waist band extending progressively from edge
Inventor: NEBEL ERHARD
IPC: D04B1/24
Filed: 1972-03-10
Abstract: Designed for one-piece stocking tights developed on a circular knitting machine, rubber stretch yarns are introduced in the waist band zone in a stitch construction such that the stitches of stretch yarn at the edge are less extended than those further away which extend over several rows.
