Abstract: 967, 162. Fuel elements. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 8, 1963 [Aug. 16, 1962], No. 31333/63. Heading G6C. A nuclear fuel element for gas cooled reactors comprises a cluster of fuel rods held in a fixed lattice by structural members including two end grids, fuel spaces within the fuel rods being interconnected via small channels in one of the end grids to which the fuel rods are attached, the interconnected spaces being further connected with free spaces formed in rigid structural members connecting the grids. The spaces act as reservoirs for fission product gases, and the fuel rods, preferably canned uranium dioxide rings, are preferably free to slide in the other grid to allow for relative expansion. The fuel rods 2 have brazed welded or soldered end plugs 3, 4, the channelled end plugs 3 being brazed to the channelled grid 7. The axially free ends of the fuel rods have extensions 11 which slide in the other end grid 10. The two grids are held together by a series of hollow tie rods 16, the spaces therein being connected to channels 14 in the end grid 7. After brazing the fuel rod plugs to the end grid 7, the assembly is completed by closing joint access holes in the grid with plugs 13. In a modification, (Fig. 3, not shown) the grid to which the fuel rod plugs are brazed is made in two disc like halves which are jointed after brazing the fuel rod plugs. The additional gas space provided by the hollow tie rods may be supplemented or replaced by space provided in a central non fissile rod and/or an outer jacket. The central rod mentioned may act as the only tie between the two grids.

Abstract: 1278482 Photocells GENERAL ELECTRIC CO 20 June 1969 [5 July 1968] 31377/69 Heading H1K A detector of ultra-violet radiation consists of a semi-conductor body with a metallic film forming a Schottky barrier with one face, the film exhibiting a sharp increase in transmission at a quantum energy in excess of the band gap energy of the semi-conductor. The body may be of N- or P-type Si, ZnS, ZnSe, CdS, SiC, GaP or GaAs and the electrode or the filter part thereof of silver, rhenium oxide, or an alloy of tungsten oxide and sodium. Its thickness can be varied to alter the selectivity and sensitivity of the detector. One embodiment shown in Fig. 3 is formed from an N-type GaAs wafer containing from 5 x 10<SP>15</SP> to 5 x 10<SP>17</SP> donors/c.c., which after lapping and polishing to a thickness of 125-500 Á has one face coated with 5000Š of silver by evaporation. After heating in hydrogen at 450‹ C. for 30 seconds to form this into an ohmic contact the opposite face is lapped and etched and coated first with 5000Š of silica 30 and then with 2000Š of aluminium 31. After forming an aperture in these lavers by photoresist and etching steps 2000Š of silver 41 is deposited via a mask followed by an antireflection coating 43 of magnesium fluoride. Finally after attaching the wafer to a KOVAR (Registered Trade Mark) base 15 with lead or indium solder, wire 44 is soldered on with lead. The platinum, which serves to prevent reaction between the silver and gallium arsenide, may be replaced by tungsten, chromium or molybdenum, or omitted altogether if high operating temperatures are not contemplated. In this case the processes subsequent to and including silver deposition must be effected at low temperatures. In a further modification the silica and aluminium layers are also omitted. Wire 44 is in this case connected directly to the silver electrode the edges of which are masked with black painted black wax.

Title: A process for the purification of silver nitrate solutions
IPC: C01G5/00
Filed: 1958-10-07
Abstract: Solutions of silver nitrate contaminated with other metals are purified by adding silver oxide until the pH of the solution is at least 6.1, preferably between 6.1 and 9.0, exposing the solution to ultra-violet light, preferably having a high proportion of illumination around 2537  , separating the resulting precipitate, and contacting the solution with a water insoluble porous basic adsorbent, preferably alumina or magnesia; alumina coated with silver oxide or silver oxide coated glass filters may also be employed. Activated alumina or magnesia may be employed in an amount of 2-10% by weight of the silver nitrate.  The solution may be passed through a column of the adsorbent and the issuing solution may be passed through a microporous filter, e.g. a stainless steel, clay ceramic, or fritted glass, which may have an average pore size of 5 microns or less.  Suitable sources of ultraviolet light include carbon arcs, argon glow lamps, photographic flood lamps, fluorescent lamps with ultraviolet light emitting phosphors, and, preferably, mercury vapour arcs. The irradiation may be carried out in stirred vessels, or by flowing the solution in a thin film past the source, or by passing the solution through quartz or other ultraviolet light transmitting tubes past the source.  Activated alumina columns may be regenerated by washing with 33-70% nitric acid, 0.5-1.0% nitric acid, distilled water, about 0.25-3 molar sodium hydroxide, and distilled water in succession.
