Title: Magnetically driven motor - has several rotating magnet systems connect by gearing to driving shaft
Inventor: MUELLER-MAHN WERNER
IPC: H02K53/00
Filed: 1973-11-07
Abstract: The motor comprises an output shaft which also carries a driving sprocket. Arranged around the shaft are several magnet assemblies coupled to the sprocket by gear wheels. Each assembly comprises several permanent magnet segments attached to plungers which can vary the radial position of individual segments with respect to the magnet assembly shaft. Mounted on the driving sprocket by means of hinges near the periphery are armature links with concave faces to match the curvature of the magnet segments. The radially inner face of each segment has a cam which runs in a groove in the machine frame. Cam and groove position the link with respect to the magnet. Successive inward and outward movement of the magnets causes attraction of the armature links and imparts rotary motion to the whole system.

Title: Effective quantum yield of photo-multiplier - has sensitivity increased by redirection of cathode reflected light back to light sensitive cathode spot
Inventor: STEINBACH MANFRED DR
IPC: H01J40/02
Filed: 1974-06-14
Abstract: The reflecting surfaces are part of a prism mounted on the cathode. The incoming light beam as well as the cathode reflected beam are at right angles to the reflecting surfaces. Light from an image spot is reflected back on its path from the fully silvered rear surface of the prism, and as the cathode surface is sensitive to light the spot is brightened. The incoming beam which needs to be intensified enters through a partially silvered surface of the prism. The intensified beam returns along the path of the incoming beam.

Title: Sternpost tube sealing arrangement - has sealing rings which are not distorted when assembled in clamping ring
Inventor: HISADA NAOJI
IPC: F16J15/3268
