Title: Process and apparatus for the continuous production of cyanohydrins
Inventor: SENNEWALD KURT
Filed: 1959-12-29
Abstract: Cyanohydrins are prepared in a continuous manner by reacting aliphatic carbonyl compounds with hydrocyanic acid in the presence of a catalyst having an alkaline reaction, wherein the carbonyl compounds and the hydrocyanic acid are continuously introduced into a reaction unit containing the catalyst and a diluent in 10- to 400-fold excess of the starting substances and are conducted in a cycle, temperatures of 5 DEG C. to 20 DEG C. and a pH of 6 to 8 being maintained, the resulting reaction mixture being continuously drawn off and conducted into a sojourn zone maintained at 0 DEG C. to 10 DEG C. where it remains until the reaction is complete.  Diluents may be water, hydrocarbons or the cyanohydrin obtained as a reaction product.  Carbonyl compounds exemplified are acetaldehyde, crotonaldehyde and acetone, yielding lactic nitrile, crotonaldehyde cyanohydrin and acetone cyanohydrin, respectively, as final products.

Abstract: 1410397 Dispersible insoluble sulphur KALICHEMIE AG 20 Sept 1973 [27 Sept 1972] 44281/73 Heading C1A Dispersible insoluble sulphur is prepared by granulating a mixture of insoluble sulphur as defined and a processing oil of the kind conventionally used for the production of oiled insoluble sulphur and the surface tension of which has been reduced by addition of 0À5 to 10% by weight of the final composition of an organic anionic or non-ionic wetting agent the mixing proceeding until granulation is initiated, after which the mixing is continued until the desired granulated material is formed. The oil may be used in an amount of from 10 to 60% by weight of the final mixture. Numerous wetting agents are specified. If desired a solvent such as butanol, isobutanol, propanol or isopropanol may be added to the surface-active compound. The granulation may be carried out in a high intensity mixer. An excess of processing oil of reduced surface tension may be used, the resultant granules being hardened by dusting with insoluble sulphur.

A recording and/or playback amplifier Fig. 4 includes a low pass filter 12 having a circuit element, e.g. lamp 18, whose impedance depends on signal level so that the cut off frequency of the filter is reduced as the signal level reduces, to reduce the disturbing effects of high frequency noise components. The filter may alternatively be formed by a series negative temperature coefficient resistor and a shunt capacitor. As shown the lamp 18 is also used to provide automatic gain control by varying the resistance of the photo sensitive resistor 20 in the negative feedback path 19 of the amplifier.

Title: Improvements in or relating to the manufacture of products containing radio-active materials
Inventor: LEFILLATRE GUY
IPC: G21F9/16
Filed: 1962-11-28
Abstract: 959,751. Radio-active materials. COMMISSARIAT A L'ENERGIE ATOMIQUE. Nov. 28,1962 [Dec. 6, 1961], No. 45043/62. Heading G6R. A method of producing solid radio-active waste from aqueous mud comprises mixing bitumen and a surfactant with the mud at a temperature between ambient and 95C. thereby bitumen coating the mud and separating the majority of water contained therein, decanting the water, working the bituminous mastic thus obtained at a temperature at which it becomes fluid, and casting the liquid to form solid blocks. It is preferable to distillate the remaining water at approximately 100C. after decanting and prior to the working or second mixing. Up to 90% of the water can be removed without distillation. The addition oi 1 to 20% of the bitumen weight of a surfactant, such as potassium naphenate or calcium naphthenate, facilitates, in conjunction with forced agitation, the formation in the mixing tank of water/mud and solids/bitumen mixtures; on cessation of the agitating, the surfactant aids in the separation from the mud of the bulk of the water, furthermore it improves adhesion between the bitumen and the mud particles. The wetting agent can be added to the mud prior to the addition of the bitumen, or can be added to the bitumen prior to the latter being added to the mud. The bitumen may be fluidised by the addition of non polar solvents (15-33%), such as kerosene, or by heating. The bitumen may either be added all at once prior to the commencement of agitation, or part may be added at this stage, and the remainder after distillation of the residue water, in which case this second bitumen addition may have a higher softening point than the first..In the case of a single addition of bitumen, one having a softening point of 40 to 65C. is used, the first mixing being at 60 to 90C. When two additions of bitumen are used, the first has a softening point of 30 to 45C., and is fluidised for mixing at ambient temperature by the addition of solvent; the second bitumen, softening point 80 to 130C., is.added during mixing after distillation. The bituminous mastic obtained is hot poured into moulds to form blocks on cooling. The moulds may be used as permanent containers for the radioactive waste cast therein, or the blocks may be removed and stored without protective receptacles, or placed in other storage vessels.

To compensate for thermal inertia due to the mass of a thermometer probe, two sensing elements 2, 4 Fig.2 or Fig.3 (not shown) are mounted on the probe tip 1. The element 2 comprises a double thermocouple Fig.1 in good thermal contact with the medium 3 under test. The output of one thermocouple of element 2 is compared with the output of the thermocouple element 4 in a difference detector 5, the output of which is fed to a multiplier 6. The multiplier output constitutes a correction signal which is superimposed on a temperature value measured by the other thermocouple of element 2, in a unit 7 and the result is indicated in meter 8. When equilibrium is established the correction signal from multiplier 6 is zero; but before equilibrium the difference voltage is representative of the temperature drop in the probe and of the heat transmitted from the medium 3 to the probe which makes the temperature of the medium in the vicinity of element 2 different from that of the main bulk of the medium, and consequently without the correction, the measurement would be inaccurate.
