IPC: C07J75/00
Filed: 1938-08-03
Abstract: 517,435. Sex hormones. SOC. OF CHEMICAL INDUSTRY IN BASLE. July 27, 1938, Nos. 22348 and 22349. Convention dates, Aug. 4, 1937, and June 24, 1938. [Class 2 (iii)] Homologous saturated or unsaturated carbonyl compounds obtainable by the side chain degradation of sterols are separated and purified by reaction with carbonyl reagents containing in addition to the group capable of condensing with the carbonyl group a salt forming group or a group capable of conversion into a salt forming group followed by decomposition of the condensation product, characterized in that the mixture of carbonyl compounds is caused to react with the carbonyl reagents only partially and/or the condensation products obtained are decomposed by stages. The partial condensation may be effected by condensation at low temperatures, and the decomposition by stages may be effected by the use of different hydrogen ion concentrations. Suitable carbonyl reagents are basic hydrazides such as trialkylammonium or pyridinium fatty acid hydrazides or salts thereof such as trimethylammonium acetic acid hydrazide chloride, or acid hydrazides such as arylhydrazinesulphonic acids. The mixtures of homologous carbonyl compounds are particularly those obtained by the oxidation of sterols such as cholestanols, cholesterols, stigmasterol, cinchol, sitosterol, ergosterol, bile acids or their sterioisomers and derivatives such as esters and ethers. In examples (1) an alcoholic solution of the chromic acid oxidation product of cholesterol-dibromide acetate containing 10 per cent. of glacial acetic acid is treated with trimethylammonium acetic acid hydrazide by boiling for ¢ hour. Water is then added and nine-tenths of the acid is neutralized with sodium carbonate, and the non-ketonic fraction extracted with ether. The mother liquor is acidified with tartaric acid to congo and extracted with ether to give nor-cholestenolone acetate and pregnendone acetate which can be separated by fractional crystallization. The mother liquor is acidified with hydrochloric acid and again extracted with ether to give trans-dehydroandrosterone acetate. Instead of adding water as above it is also possible to work in an anhydrous medium using as a solvent a hydroxylic body such as glycol or glycerine. (2) A methyl alcoholic solution of the neutral fraction of the oxidation product of cholestenone with chromic acid containing 10 per cent. of acetic acid is treated with trimethylammonium acetic acid hydrazide. A fractional extraction is then performed as in example (1) to give pregnendione and nor-cholestenone from the less strongly active liquor and androstenedione from the more strongly acid liquid. (3) The hydroxy-ketone resulting from the oxidation of cholesterol acetate dibromide is treated as in example (1) but with the chloride of pyridinium acetic acid hydrazide and worked up as in examples (1) and (2) to give from the less acid liquor nor-cholestenone and pregnenolone, and from the more acid liquor transdehydroandrosterone.

Title: Improvements in or relating to the production of hexachlorocyclohexane
IPC: C07C17/02
Filed: 1954-01-25
Abstract: Benzen is chlorinated in admixture with methyl chloride, methylene chloride, chloroform, 1:1-dichloroethane or ethylene dichloride, or mixtures of these at - 40 DEG C. to + 40 DEG C. in actinic light, the intensity of light and the rate or introduction of chlorine being adjusted to maintain the concentration of free chlorine in the mixture at not more than 5 per cent by weight of the total, and between limits shown on the accompanying Figure, to give a product having a high content of gamma isomer. Tables are given of a series of batch experiments carried out with methylene chloride, ethylene dichloride, chloroform and 1:1-dichloroethane at temperatures of - 25 DEG C. to + 25 DEG C., the free chlorine concentrations differing at selected temperatures and the quantity of gamma isomer being estimated at such points. The maximum gamma product content for a particular temperature and solvent was obtained from the paraboloid graphs, and the free chlorine concentrations as upper and lower limits corresponding to a gamma content of 90 per cent of the maximum plotted against temperature gave a <PICT:0743913/IV(a)/1> graph of approximately 2 straight lines using a logarithmic scale for the chlorine content, from which the desired limits for free chlorine concentration for any particular temperature may be determined. Actinic light is provided by mercury arc lamps, the intensity being varied to give the desired concentration of free chlorine. A further example describes 5 batches of a chlorination process in methylene chloride at - 25 DEG C. with free chlorine maintained at 0.05 per cent to 0.3 per cent continued until 28 per cent of the benzene had been converted to hexachloride, to give high yields of the gamma product.

Title: Coupling hook
IPC: F16G11/00
Filed: 1964-09-19
Abstract: Two identical sister hooks 1, each with a pair of lugs 7, are pivoted together on a pin 3 (with the lugs interdigitated) so that when the hooks are swung together, flat faces 4 engage each other and a load cable of a winch, crane or tractor is completely encircled. Each hook 1 has a recess 8 adjacent each pair of lugs 7 and the two recesses are aligned for a cable 9, e.g. attached to a log, timber &c., to pass through for securement to the pair of hooks. The cable 9 tends to close the hooks together on no load and an end stop on the cable forces them together on load. The outer faces 5 of the hooks may be completely curved, or only at their inner edges. On each hook, the lug 7 nearer the hook opening 6 may be wider than the other. A number of hooks each attached to a load by a cable 9 may be latched side-by-side on a load cable attached to a winch, crane or tractor, e.g. for use in forestry. A load cable may be secured in the recesses 8 and the hooks encircle the cable elsewhere, to form a lasso loop to enclose a bundle of timber without the use of separate cables 9. The width of the hook openings is 1.2 -1.5 times the load cable diameter and the diameter of the ring formed by the closed hooks is not more than 2.5 times that diameter.

Title: Bearing trunnions
IPC: F16C19/24
Filed: 1964-09-26
Abstract: In a ball or roller bearing having a non- rotatable inner race 12, compensation for distortion of the outer race 11 when a radial force P is applied thereto is effected by shaping the inner race so as to render the radial distance between the two races uniform and the loads carried by the balls or rollers 13 ... 161 substantially similar to one another, the shape of the inner race being substantially elliptical when a single radial-force is applied to the bearing. When a plurality of radial forces are applied to the bearing, the radii of curvature of the profile of the inner race are determined in accordance with the magnitudes and directions of said forces so as to effect uniform loading of the balls or rollers. The inner race may be constituted by a solid shaft or hollow resilientlydeformable shaft (32), Fig. 4 (not shown). The hollow shaft may be rendered elliptical by insertion of an elliptical auxiliary member therein before a grinding operation, said member being removed when said operation has been completed. Alternatively, the inner race may be constituted by a ring mounted on a shaft. It is stated that the balls or rollers may be omitted, the outer race being in direct contact with the inner race.

Title: Surface treatment for jointly improving friction and fluidtightness
IPC: F16C33/12
Filed: 1965-07-08
Abstract: A method of treating the bearing surfaces of metal parts comprises the steps of machining the surface in such a manner that the predominant direction of the machining marks is perpendicular to direction of rubbing of the bearing when in use, heat treating the surface to introduce a non-metallic substance or transition metal into the surface and finally work hardening the surface with rollers. As described the surface is preferably machined to a roughness of 2À5 to 3 microns and the surface treated in a salt bath or gaseous atmosphere to introduce nitrogen, sulphur, selenium or tellurium. Two treatments may be given to introduce consecutively sulphur and nitrogen. As well as work hardening the surface the rolling is stated to have the effect of causing nitride rodlets precipitated from the metal to revert to a state of solution.
