Patent GB-2098792-A (GB)
Title: Dynode substrates
IPC: H01J9/12
Filed: 1981-05-13
Abstract: In discrete dynode channel plate electron multipliers, for use, for example, as raster intensifiers in a cathode ray tube, the dynode plates 2,3 are perforated mild steel sheets as used for shadow masks in colour television tubes. The steel sheets are coated with an oxidised chromium layer which will bond well to glass, be thin enough not to degrade the mechanical key provided by the etched steel, be oxidiseable at a low temperature to avoid stress relieving the steel, and which will also provide an effective barrier to the migration of iron from the steel into a secondary emitter 5, degrading its performance. A layer of evaporated chromium 0.1 mu m thick has been found to be suitable in all these respects. A stack of such plates is bonded together but electrically insulated from one another, preferably with glass 4, to form the multiplier, the insides of the perforations being coated with the secondary emitter 5. <IMAGE>

Title: Passive safety belt system
Inventor: ELSE ROBERT FREDERICK
IPC: B60R22/04
Filed: 1983-08-11
Abstract: In a passive safety belt system for a motor vehicle, the belt is moved away from the body of the user when the corresponding vehicle door 10 is opened.

Title: Tidal water buoy
Inventor: JANKO AMBRUS GYULA PETER
IPC: B63B22/18
Filed: 1983-11-11
Abstract: The Tidal Water Buoy keeps its trim in varying velocities and depths of water. The relatively lean bow suffers no significant lift by the bow wave nor by dynamic forces at higher flow velocities. What buoyant or dynamic lift occurs at the bow is balanced by both buoyant and dynamic forces at the stern of the buoy, the stern being either curved downwards or furnished with suitably angled flaps and fins also, for good directional stability. Minor trimming can be achieved by chosing the mooring attachment point 7 suitably and by positioning the weights carried above or below the deck. The Tidal Water Buoy is made of a plurality of materials and the techniques of manufacture are numerous. The Tidal Water Buoy is suitable for personnel or cargo of any description to be loaded on or in it, and for other vessels to be moored to it. <IMAGE>
