Title: Determn. of diffusion of solid, liquid or gas - by heating in capsule sealed with solid membrane and ionising diffused particles
Inventor: WU CHUNG HSIUNG DR
IPC: G01N13/00
Filed: 1975-12-13
Abstract: Determn. of the diffusion of particles of material(s) (I) existing in the solid, liq. or gaseous aggregate state at normal temp. through another material (II) existing in solid form involves placing a (I) sample in a capsule sealed with a (II) membrane and heating the capsule to a predetermined temp. A proportion of the (I) particles passing through the membrane are ionised by electron bombardment and determined. The temp. is attained in the min. time possible and the size of the temp. interval is measured, so that the determn. is sufficiently accurate. Method can be used e.g. for determn. of the diffusion of Li in Mo, W, Ta, Nb, Ti or Re; Al or Cu through Fe; Al through Cu; Hg through Cu, Al, Fe; metals through quartz; or a gas through solids. The method is simple and more accurate than usual. It depends on Fick's second law. Method applies e.g. to development of nuclear fuel elements.

Title: Spiral ball bearing for rotating shaft - has spiral grooves with different angle of inclination at pole and equator
Inventor: HERBERT WERNER DIPL ING
IPC: F16C33/10
Filed: 1976-08-06
Abstract: The ball bearing is designed for a shaft rotating in one direction and has a spherical segment and a ball provided with spiral grooves between the pole (6) and equator (8) regions. The angles of inclination of the grooves differ from one another between these two regions. The barrier-groove ratio at the pole is less than that at the equator. The groove depth and width along each spiral groove are different. Where the barrier width (12) is sufficient in the region of the equator the grooves branch out. The spherical form of the segment deviates from that of the sphere to create a lubricating gap which decreases from the pole to the equator.
