Patent ES-329458-A1 (ES)
Title: Preparation of a filterable co-precipitate of plutonium and uranium
IPC: C01G43/025
Filed: 1966-07-23
Abstract: In the preparation of a PnO 2 -UO 2 mixture for nuclear fuel element fabrication, a solution containing Pn and U in a mole concentration ratio of between 0.82 and 1.22 is treated with ammonium hydroxide to precipitate a mixture of uranium and plutonium hydrous oxides, and the precipitate is filtered, washed, dried, and heated in a hydrogen atmosphere at 600- 900 C. to reduce the mixture to oxide. The precipitate is more readily filtered and dried than precipitates in which the Pn and U molar concentrations differ. Ammonia is added to an aqueous solution of uranyl nitrate and plutonium nitrate to form a flocculent precipitate which after drying is reduced in hydrogenhelium. The product may be mixed with UO 2 or PnO 2 to adjust the Pn: U ratio, and then compacted and sintered to form fuel pellets.

Filed: 1967-08-16
Abstract: The throat armour of a blast furnace comprises several sections each adjustable by an automatically balanced bridge network, and includes means for continuously comparing the positions of the sections to ensure that they operate synchronously. As shown Fig.1, a three section armour throat has each section linked to the slides 4 of a potentiometer 3, inter-connected in a first bridge network with relays 7 1 -7 3 in the unbalance diagonals, and in a second bridge network with control potentiometers, with relays 6 1 -6 3 in the unblance diagonals Thus, exciting the sliders 5 on potentiometers 1 to adjust the throat size, energizes relays 6 1 -6 3 to energize motors which adjust the throat size and drive the sliders 4 to the balance positions. Any potential difference between adjacent sliders 4 energize a relay 7 1 -7 3 to stop an adjusting motor until the throat sections are again in step.
