Title: Improvements in or relating to a stable substantially anhydrous grease and preparation of same
IPC: C07C51/41
Filed: 1954-10-20
Abstract: A substantially anhydrous lubricating grease comprises an oleaginous liquid containing a substantial proportion of a naphthenic lubricating oil having a viscosity below 600 SUS at 100 DEG F. and 5-20 per cent by weight, based on the total composition, of an alkaline earth metal salt of a hydroxy, fatty acid containing at least 12 carbon atoms in its molecule.  A process of preparing a substantially anhydrous lubricating grease comprises saponifying a hydroxy fatty acid containing at least 12 carbon atoms in its molecule or a glyceride thereof with an alkaline earth metal hydroxide in the presence of a small amount, equivalent to only a minor proportion of the oleaginous liquid employed in the finished grease, of the above mentioned naphthenic lubricating oil, heating the saponified mass at a temperature above the melting point of the resulting soap for a time sufficient to substantially dehydrate the mass and then gradually adding the remainder of the oleaginous liquid with continuous stirring as the mass is cooled to a temperature below the melting point of the soap.  The oleaginous liquid added during cooling may be the same naphthenic lubricating oil as was added initially.  Alternatively, the oleaginous liquid added during cooling may be a different mineral lubricating oil which may be distillate or residue, paraffinic or naphthenic, or a mixture of such oils, as a further alternative, the oleaginous liquid added during cooling may be a synthetic lubricating oil, particularly an ester of an aliphatic dicarboxylic acid such as 2-ethyl hexyl sebacate, or a mixture of a synthetic oil with a mineral oil. Suitable hydroxy fatty acids are 9, 10- and 12- hydroxy stearic acids, 9, 10-dihydroxy stearic acid and 8-hydroxy palmitic acid and they may contain estolides as described in Specification 771,797.  Specified alkaline earth metal salts are calcium, barium and strontium 12-hydroxy stearates, barium 10-hydroxy myristate, strontium 12-hydroxy oleate, barium 9-hydroxy stearate and strontium 10-hydroxy stearate.  Additional ingredients which may be present in the lubricating grease are extreme pressure agents, pour depressants, oxidation inhibitors (particularly amines such as diphenylamine, a - and b - naphthlamines and N, N1-diphenyl-p-phenylene diamine) corrosion inhibitors and dyes.  In particular, a blend of sorbitan mono-oleate as corrosion inhibitor and "Ortholeum 300" (a mixture of diphenylamine and salicylataminoguanidine oleate) as oxidation inhibitor may be added. In the examples, the preparation of lubricating grease from naphthenic distillate mineral lubricating oil, residual mineral oil, 12-hydroxy stearic-acid (either containing estolide or estolide-free), lime, sorbitan mono-oleate and "Ortholeum 300" is described.  For comparison purposes, the preparation of lubricating grease from paraffinic distillate mineral lubricating oil, estolide, containing 12-hydroxy stearic acid and lime is described.

Title: Production of u
IPC: G21G1/02
Filed: 1945-11-15
Abstract: 873,171. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 15, 1945 [Nov. 3, 1944], No. 30680/45. Class 39(4). Uranium 233 is produced by subjecting thorium to the action of neutrons the majority of which have an energy of below 1 mev. and by terminating this reaction before the ratio of uranium 233 to thorium is about 1 to 100. Preferably the reaction is terminated when the ratio of uranium 233 plus protoactinium 233 to thorium is between 1 to 1 million and 1 to ten thousand. The thorium is bombarded with 10<SP>15</SP> neutrons per second for a period of at least one month. The neutrons may be obtained from a fast neutron source using . moderator materials containing carbon, deuterium or hydrogen; such as graphite, paraffin, water or heavy water. The reason for terminating the reaction at the specified stage is to prevent excessive wastage of uranium 233 by fission. It is preferred that the thorium should not contain more than sufficient natural uranium to dilute the uranium 233 by more than 20%. The uranium may be extracted by dissolving the thorium compound in nitric or hydrochloric acid, adjusting to pH of about 3 and precipitating both uranium and thorium with an excess of hydrogen peroxide. After removal of the supernatant liquid the precipitate is treated with alkali such as sodium hydroxide and a solution containing the uranium peroxide but not the thorium peroxide results. The uranium may then be separated by acidifying with nitric or hydrochloric acid. The fission products precipitated with the uranium at this stage may be separated by dissolving and precipitating several times. Alternatively the fission products may be removed by crystallizing out uranyl nitrate hexahydrate and dissolving this compound in ether. In an alternative process the thorium is precipitated as a fluoride, iodate, oxylate or phosphate. In the foregoing process the protoactinium is removed with the thorium but it may be separately processed by means of manganese dioxide precipitates dissolved in a mixture of hydrogen peroxide and hydrochloric acid, adding zirconium oxychloride and precipitating the zirconium as zirconium phosphate. Further details of the process are described -in Specification 30681/45.
