Title: Process for the manufacture of aliphatic, olefinically unsaturated dicarboxylic acids
IPC: B01J27/198
Filed: 1962-01-26
Abstract: Aliphatic olefinically unsaturated dicarboxylic acids or anhydrides thereof are prepared by contacting an olefinic hydrocarbon having 4 carbon atoms in a straight chain and molecular oxygen at a raised temperature with a catalyst comprising vanadium pentoxide, phosphoric acid and an inorganic carrier, which has an increasing activity in the direction of flow of the gas mixture.  To effect this the phosphoric acid to vanadium pentoxide ratio in the catalyst may be decreased in the direction of flow or the gases may be passed through two or more layers of catalyst, the second and following layers having a higher activity than the previous ones. The preferred temperatures for carrying out the process one in the range 350-550 DEG  C. and the preferred carrier is kieselguhr.  Suitable starting materials are, for example, butene-1, cis-butene-2, trans-butene-2 and butadiene which are oxidized to maleic acid or 2-methyl-butene-2 which is oxidized to citraconic acid.  The anhydrides are obtained if the products are cooled directly or washed with an organic solvent.

Reciprocating-mould-table machines; feeding; cutting-apparatus.-Cakes or pellets are moulded by mechanism which picks up a charge of plastic or powdered material from a trough J and transfers it to a die plate F' and pressing plunger H<2>. The charging-chambers L are carried by a vertically reciprocated support K and are turned over when the shaft K<1> is rotated by a quadrant G<2>, vertical shaft K<3>, and sliding pinion K<5>. On the downward stroke of the support K, a chamber L dips into the trough and seizes a charge. As the support rises, the excess of material is removed by a baffle J<1>, the shaft K<1> turns, and the charged chamber is brought into register with the perforation in the die plate F'. Locking-members M hold the plate stationary during the pressing operation. Further upward movement of the support K causes the upper chamber L to yield and slide over its plunger and expel the charge into the plate F<1> which is reciprocated by quadrants G and racks F<2> to bring the pellets under ejecting-plungers on each side of the plunger H<2>. The plunger H<2> may be omitted and the plate F<1> recessed to form dies, or it may carry hays or tins. Alternatively, the charges may be brought first between shaping- dies and then unler the ejecting-plungers. The trough J may have a false bottom to deliver pellets of varying thickness, and may be rotated.

Abstract: 1338982 Eccentricity measurement CINCINNATI MILACRON Inc 26 Jan 1972 [23 Feb 1971] 3735/72 Heading G4H Eccentricities in a rotation of an unloaded shaft are compensated for by, at a plurality of timing instants, converting analogue deflection signals for an idly rotating shaft to a sequence of digital signals which are stored, reconverting these stored values cyclically to an analogue signal and subtracting this signal from the deflection signals produced by a loaded shaft. Transducers 40, 42 sense eccentricities of shaft 38 as it rotates and the output signals are amplified (44, 46) and compared at 48 to give an error signal. An encoder 50 comprising a toothed wheel on shaft 38 and a pick-up feeds pulses to timing signal generator 52. The arrival of a pulse at generator 52 sets the A/D converter 58 in operation and causes a counter in address circuit 60 to advance and address, via a decoder, a unique address in store 62. The digital value previously stored in this address is transferred to buffer store 52 and the address is cleared. When the A/D conversion is completed, the digital value is transferred to store 62. The next pulse from encoder 50 causes a similar procedure for the next storage element; the number of addresses in the store being equal to the number of teeth on the toothed wheel. When the eccentricities of a loaded shaft are being measured, sensor balance control 56 operates to prevent operation of converter 58 and further entries into the store. Eccentricity signals are fed into buffer store 64 in response to the signals from encoder 50 and the signals are converted to analogue values at 66 and subtracted from the loaded shaft eccentricity readings at 68.

Title: Separation of plutonium
IPC: C01G56/00
Filed: 1946-02-06
Abstract: 843,481. Separation of plutonium. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 6, 1946 [Feb. 3, 1945], No. 3809/46. Drawings to Specification. Class 39(4). Plutonium is recovered from solution by forming a precipitate of a fluoride in the solution together with a precipitate of lead sulphate, whereby plutonium is carried down with the fluoride precipitate. The lead sulphate gives a more rapid settling of the precipitate and an improved separation of plutonium. Lanthanum fluoride is the preferred fluoride, but potassium plutonium fluoride is also referred to. The solution treated may be that obtained following bismuth phosphate precipitation of a solution of neutron-irradiated uranium according to U.S.A. Specification 2,785,951. The fluoride and lead sulphate precipitates are preferably formed at the same time by mixing solutions containing hydrogen fluoride, lanthanum nitrate, lead nitrate, and sulphuric acid. The lanthanum nitrate solution may be added to the hydrogen fluoride solution or vice versa. The precipitate is digested before separation and may then be washed and treated with alkali to form a lanthanum hydroxide precipitate which carries the plutonium, leaving the lead in solution ; the precipitate may be dissolved in nitric acid and plutonium precipitated as fluoride or peroxide. The Specification as open to inspection under Section 91 refers also to the presence of lead sulphate during the precipitation of impurities with a fluoride, leaving the plutonium in solution in the oxidised state; the addition of stannic, aluminium, antimony, and arsenic compounds in place of lead sulphate is also mentioned. An additional example describes the improved precipitation of lanthanum fluoride in the presence of lead ions without precipitation of the sulphate. This subject-matter does not appear in the Specification as accepted.
