Abstract: 1,148,478. Sintered oxides. COMMISSARIAT A L'ENERGIE ATOMIQUE. 2 Feb., 1968 [13 Feb., 1967], No. 5415/68. Heading C1A. [Also in Division G6] Sintered pellets of UO 2 , PuO 2  or ThO 2  or mixtures thereof, for use as nuclear fuel, are made by grinding the oxide(s) into powder, adding to the powder 1 to 7% by weight of a fatty acid salt as a sintering inhibitor, preferably zinc behenate or zinc stearate, cold-pressing the mixture into bodies, breaking the bodies into granules, coating the granules with the sintering inhibitor in a proportion between 0À2 and 1% by weight, cold-pressing the coated granules into pellets, and sintering the pellets in a reducing atmosphere at a temperature equal to or higher than 1500 C. In one example, a finely divided powder of zinc behenate is added to a finely divided UO 2  powder and pellet-shaped bodies of the UO 2 /zinc behenate powder are prepared in an hydraulic press under a pressure of about 1500 bars. The bodies are broken in a mill and only those that pass through a screen of 0À6 mm. but not one of 0À3 mm. are retained. These are coated with between 0À2 and 0À3% by weight of finely-divided zinc behenate in a conventional mixer and shaped by cold-pressing under a pressure between 4000 and 7000 bars to obtain pellets having the desired final shape, except that shrinkage is taken into account. The pellets are sintered for 3 hours in a reducing atmosphere at 1700 C. The density of the pellets is 90% of the theoretical density with 1% zinc behenate added during the first mixing step, 85% with 2À5 to 3% zinc behenate, and 80% with 5% zinc behenate. Such pellets are more suited to retain fission products without the cracks found in higher density pellets when subjected to high burn-up. The manufacture of annular pellets made of a mixed dioxide of enriched uranium and plutonium (U 0 . 8 , PU 0À2 )O 2  for use as fuel elements in a fast reactor is also described.

Title: Improvements in and relating to high frequency variable inductance tuning devices
IPC: H01F21/00
Filed: 1950-03-03
Abstract: 672,830. Inductances. MALLORY & CO., Inc., P. R. March 3, 1950 [March 29, 1949], No. 5477/50. Class 38 (ii). A variable inductance for tuning high frequency signals, covering a substantial band, of the type including a lumped inductance 13 is characterized by at least one inductance in strip form coupled thereto, conductors and a movable contactor 11 for conducting the high frequency signals to the inductances and a shading element 16 attached to the contactor 11 and so arranged with respect to the lumped inductance 13 that for a position of the contactor 11 contiguous to the coupling of the inductances the eddy current effect of the shading element on the lumped inductance is very high, continued movement of the contactor away from the lumped inductance in contact with the strip inductance causing a gradually increasing inductive effect of the lumped inductance augmented by the portion of the strip inductance included with the lumped inductance. The strip inductance comprises two portions 10, 12, the portion 10 being tapered to render the tuning linear, together with a continuous centre member 24, a connecting piece 26 and terminals 25, 33. The contactor 11 is secured to a rotatable shaft 21 and is arranged to bridge the member 24 and the sector 10 or the sector 12. This arrangement allows the tuning, without the conventional intermediate switching of two high-frequency bands which are separated by a band of frequencies commonly known as the dead zone. Movement of the contactor around the sector 10 effects tuning over one band of frequencies-the higher frequency band-a further movement of the contactor, governed by the width of the air gap 15 between the sector 10, 12 then being sufficient to alter the connections to the coil 13 and to transfer the contactor from sector 10 to sector 12 and so enable tuning over another band of frequencies-a lower frequency bandto be accomplished. The shading of the lumped inductance coil 13 by the eddy current blade 16 produces a vernier tuning effect over a portion of the lower band width. Specification 672,831 is referred to.
