Patent ES-480300-A1 (ES)
Title: Process for the recovery of magnesium oxide of high purity
IPC: C01F5/10
Filed: 1979-05-07
Abstract: The present invention relates to a process for the recovery of magnesium oxide of high purity in which the magnesium oxide is obtained by thermal decomposition of a magnesium chloride brine previously purified. The magnesium chloride brine itself is obtained by decomposition of impure starting material with hydrochloric acid and purified before the thermal decomposition. In doing so the brine obtained by the decomposition is first concentrated and the separation of the impurities is effected only then. Calcium is separated in form of calcium sulfate. Optionally calcium sulfate and other impurities may be separated together.

Title: Nuclear fuel rod loading apparatus
IPC: G21C21/02
Filed: 1979-05-29
Abstract: An apparatus incorporating a microprocessor control is provided for automatically loading nuclear fuel pellets into fuel rods commonly used in nuclear reactor cores. The apparatus comprises a split "V" trough for assembling segments of fuel pellets in rows and a shuttle to receive the fuel pellets from the split "V" trough when the two sides of the split "V" trough are opened. The pellets are weighed while in the shuttle, and the shuttle then moves the pellets into alignment with a fuel rod. A guide bushing is provided to assist the transfer of the pellets into the fuel rod. A rod carousel which holds a plurality of fuel rods presents the proper rod to the guide bushing at the appropriate stage in the loading sequence. The bushing advances to engage the fuel rod, and the shuttle advances to engage the guide bushing. The pellets are then loaded into the fuel rod by a motor operated push rod. The guide bushing includes a photocell utilized in conjunction with the push rod to measure the length of the row of fuel pellets inserted in the fuel rod. Safeguards are employed to insure that the weight and position of the fuel pellets within the fuel rod fall within certain prescribed limits. After a segment of fuel pellets has been loaded, the guide bushing disengages the fuel rod, the rod carousel transfers a new rod into position, and the entire loading operation is repeated.

Filed: 1981-05-26
Abstract: A piston-rack rotary fluid pressure actuator includes a housing [10] enclosing cylinder [11] in which is disposed a pair of pistons [12, 13] biased by springs [14 and 15] towards the centre of the cylinder. Each piston has a rack portion [16, 17] engaged with a pinion [19] on output shaft [18], and elements of low friction material [20, 21] are incorporated into the outer surface of the rack portions [16, 17] to take up forces tending to displace the rack-bearing portions towards the cylinder. Annuli [30, 31] of incompressible material keyed to the shaft [18] make rolling contact with runways [32, 33] on the rack-bearing portions and have diameters equal to that of the pitch circle diameter of the teeth of pinion [19]. By this means contact is maintained between the low-friction elements [20, 21] and the cylinder and over-meshing between the teeth of pinion [19] and racks [16, 17] is prevented.

Title: Process for the oligomerization of ethylene in methanol.
IPC: C07C67/00
Filed: 1981-06-16
Abstract: Ethylene is oligomerized by reacting ethylene in methanol under oligomerization conditions in contact with a nickel ylide defined by the following Formula I: < IMAGE > wherein R1, R2, R3, R4, R5, R6, R7 and R8 are either alike or different members selected from the group consisting of hydrogen, alkyl radicals having from about one to about 24 carbon atoms, preferably from about one to about 10 carbon atoms aryl radicals having from about six to about 20 carbon atoms, preferably from about six to about 10 carbon atoms alkenyl radicals having from about two to about 30 carbon atoms, preferably from about two to about 20 carbon atoms cycloalkyl radicals having from about three to about 40 carbon atoms, preferably about three to about 30 carbon atoms aralkyl and alkaryl radicals having from about six to about 40 carbon atoms, preferably from about six to about 30 carbon atoms a halogen radical selected from the group consisting of fluorine, chlorine, bromine and iodine, preferably chlorine a hydroxyl group an alkoxy or aryloxy group and a hydrocarbyl group, such as defined above, carrying halogen, hydroxyl or alkoxy or aryloxy provided that at least one, preferably from about one to about four, of each of R1 to R8 is a sulfonato group (-SO3-) or an alkyl, aryl, alkenyl, cycloalkyl, aralkyl or alkaryl group carrying a sulfonato group M is sulfur or oxygen, preferably oxygen E is phosphorus, arsenic, antimony or nitrogen, preferably phosphorus and F is phosphorus, arsenic or antimony, preferably phosphorus. There is thus obtained a reaction product containing (A) a methanol phase having dissolved therein the nickel ylide catalyst and (B) an alpha olefin phase. These two phases are then separated from each other to recover the alpha olefin phase. The use of methanol as the solvent medium causes the reaction product to resolve itself into two phases, an upper phase containing most of the oligomer product and a lower methanol phase carrying the catalyst dissolved therein. This permits easy separation of the product from the reaction mixture and also permits effective recycle of methanol with dissolved catalyst. The product obtained contains normal alpha olefins having from about four to about 100 carbon atoms, generally from about four to about 50 carbon atoms.
