Abstract: Chlorine dioxide is prepared from at least two reactants that react together to form chlorine dioxide by bringing the reactants rapidly into intimate contact in a reaction zone and immediately educting the chlorine dioxide formed from the reaction zone into a diluting fluid by suction generated by flow of the diluting fluid through a venturi. 
     Rapid removal of the chlorine dioxide from the reaction zone and its simultaneous dilution prevent the build-up of potentially explosive amounts thereof and permit the use of aqueous solutions of reactants of more than 10% by weight strength.

IPC: H01J17/49
Filed: 1981-09-10
Abstract: A display system and operating method in which ultraviolet radiation is produced and made to impinge on fluorescent phosphors (54) and visible through translucent protective layer (62). The ultraviolet radiation is generated by application of a potential between the cathode cells and annular anodes (46) spaced therefrom by a dielectric film (38) having apertures (44) therein aligned with the cathode cells. The assembly is hermetically sealed by a reflective backing panel (64) which defines a chamber (66) communicating with the cathode cells (22) and containing an inert gas. Display is initiated by application of a first potential across the anodes and cathodes. Ions produced in the gaseous medium impinge on the metallic coating (28) and sputter metal atoms therefrom which ionize under a second applied potential thereby to produce the ultraviolet radiation for conversion into visible radiation by the fluorescent phosphors (54).

Abstract: A process for reducing the particle current in the sub-gap range of all-Nb Josephson junctions. The process results in junctions having substantially increased values of V m . 
     In order to reduce the single particle current, the reaction between the barrier layer oxide and the counter electrode is prevented by additional process steps. After forming the tunnel barrier (4) and before depositing the counter electrode (9), the tunnel barrier surface is covered with a thin, non-continuous layer (5) of a material such as gold which is not reacting with oxygen at process conditions. Subsequently, the non-covered barrier layer surface regions (7) are strongly oxidized thereby forming an oxide layer (8) of sufficient thickness to prevent electron tunneling in these regions.

Abstract: In a mould assembly for multiple castings each mould is fed from a source of molten metal through a thin slit the width of which lies in the range 1.25 mm down to 0.25 mm. By this means the cast articles can be easily removed from the runner and riser system after casting without a machining operation so that the casting moulds can be packed closer together and more castings can be produced from each mould assembly. The thin slit also acts as a filter. 
     A particular mould assembly seen in Figure 2 is cylindrical and comprises a plurality of wedge-shaped mould segments 2 having mould cavities 4 in abutting faces. A central runner passage 6 is formed when the mould segments are assembled and the metal flows into the mould cavities through narrow slits 10 in one edge of each mould. After casting and removal of the mould the narrow flashing formed in the slits can be easily broken to remove the cast articles from the metal formed in the central runner passage.
