Title: Improvements in or relating to the preparation of vitamin d
IPC: C07C401/00
Filed: 1963-09-10
Abstract: In a process for the separation of Vitamin D3 from the irradiation products of 7-dehydrocholesterol, an adduct of Vitamin D3 and 7-dehydrocholesterol is separated from the irradiation products to leave a residue containing Vitamin D3 and the remainder of the irradiation products.  The initial irradiation products may be dissolved in ethanol, cooled to crystallize unreacted 7-dehydrocholesterol which is removed, and either the adduct is obtained as a second crop of crystals, or, preferably the ethanol is evaporated, the residue dissolved in methanol and the solution cooled to crystallize the adduct.  The adduct may be at least partially cleaved by dissolution in a polar solvent, e.g. acetone or methanol, 7-dehydrocholesterol crystallized out and removed and solvent evaporated to obtain a Vitamin D3 enriched product.  This enriched product may be esterified, e.g. with 3,5-dinitrobenzoyl chloride, the Vitamin D3 ester separated from the 7-dehydrocholesterol ester by fractional crystallization, and saponified to obtain free vitamin. The residue obtained after separation of the adduct from the methanol solution and evaporation, may be enriched by solvent partitioning, e.g. with hexane and methanol or with hexane and acetonitrile, an enriched Vitamin D3 product being recovered from the hexane phase. This enriched product may be esterified, fractionally crystallized and saponified as before to obtain free vitamin.  The 7-dehydrocholesterol obtained may be subjected to further irradiation.  Examples are given.

Abstract: 1,159,814. Electrolytic finishing of gearwheels. ZENTRALEN NAUTCHNO-IZSLEDOVATELSKY INSTITUT PO TECHNOLOGIA NA MACHINOSTROENETO. Aug. 9, 1966 [Aug. 10, 1965], No.35697/66. Heading C7B. The finishing of a gear-wheel is effected by positioning a rotary finishing tool at a predetermined clearance from the wheel, connecting the tool as cathode and wheel as anode to a D.C. supply, supplying electrolyte under pressure to the toolwheel gap, and effecting synchronous rotation of both tool and wheel and relative displacement of the tool parallel to the gear teeth while maintaining the clearance. As described the tool is a worm. The parallel displacement of the tool suffices for finishing gears with straight teeth but for gears with helical teeth a further rotation of the gearwheel relative to the tool is necessary. A device is described (see Fig.2 not shown) ensuring synchronous rotation of tool and gear-wheel and with adjustable linkage means for ensuring the necessary further relative movements for finishing the whole-face of either straight- or helicallytoothed gears.

Title: Method of obtaining a uniform output density in gas-cooled high-temperature nuclear reactors
IPC: G21C19/20
Filed: 1961-10-05
Abstract: 918,907. Nuclear reactors. BROWN, BOVERI & CIE A.G., and BETEILIGUNGSUND PATENTVERWALTUNGSGESELLSCHAFT. Oct. 5, 1961 [March 4, 1961], No. 35946/61. Class 39 (4). In a gas-cooled nuclear reactor shaped bodies, preferably balls, containing fissile, breeder, inert or moderating material are fed downwardly into the core of the reactor and form a mound or cone, the bodies being introduced into the reactor in dependence upon the size of the angle of slope of the cone. The object of the invention is to obtain a uniform neutron density in the cone and is done by a distribution of the different types of material, so that on building the cone bodies of a lower fission cross-section are placed close to the axis of the cone, and fissile material is placed around the periphery. The bodies are discharged through a tapered part of the core bottom and after discharge the upper sloping part of the cone collapses. The bodies of small fission cross-section build up the upper part of the cone and when this is completed fissile bodies fall on to the cone and roll into the peripheral zone. The building-up of the cone may be determined by electroconduction, several level gauges and by measuring the neutron distribution, but the simplest method is that from a determined amount of bodies the cone has a determined slope and reaches a maximum of about 22 degrees. The quantity of discharged spheres is determined by counting, weighing or the like, and from this result the number to be fed to the core is known, which is counted by a manual or automatic control device or a programme register.

Filed: 1937-12-31
Abstract: 491,419. Steam-power plant. SIEMENSSCHUCKERTWERKE AKT.-GES. Dec. 31, 1937, No. 36235. Convention date, Dec. 31, 1936. [Classes 110 (iii) and 122 (iii)] To cope with shortage of power in high - pressure steam-power plants owing to the failure of a power unit, the engine is divided into a high-pressure engine and two low - pressure engines operating in parallel. The intermediate pressure is so varied that upon the failure of a high-pressure or a low-pressure engine, the shortage of power can be compensated for, partly or wholly, by the low-pressure engine or engines remaining in operation. In the construction shown, with a boiler pressure of 130 atm. and one H.P. and two L.P. engines V, N<1>, N<2>, the intermediate main pressure is 16 atm. If the H.P. engine fails; high-pressure steam is supplied to the main L and its pressure increased to 24 atm. The two L.P. engines then provide the power. A construction is described wherein a L.P. engine fails. The H.P. steam is raised to 140 atm., and the I.P. main to 25 atm. If the resultant output is inadequate, an auxiliary turbine driving a boiler-feed pump and a generator, and having a surplus power equal to the residual power shortage, may be employed. In a third construction, the auxiliary engine is installed as a condensing, lower stage of the engine V, and works in parallel with the engine N<1>. More than one high-pressure and/or more than two low-pressure engines may be employed.
