Title: Improvements in or relating to the coating of molybdenum and molybdenum alloys
IPC: C23C8/60
Filed: 1958-06-17
Abstract: A molybdenum or molybdenum-base alloy article in the hot-cold worked condition is made oxidation resistant at high temperatures by enclosing it in a pack of powdered material containing a source of elemental silicon and a halogen or halogen-generating substance and then heating to a temperature above the volatilising and/or decomposition temperature of the halogen or halogen-generating substance but below the re-crystallisation temperature of the article thereby forming a surface layer comprising molybdenum silicide on the article.  The pack may comprise a filler such as alumina or clay, finely-divided silicon, and a halogen such as iodine (which is used in conjunction with an inert gas such as argon or a compound such as urea which decomposes to give off an inert gas) or an ammonium halide, optionally together with chromium to produce a surface layer of molybdenum and chromium silicides.  Heating may be effected at a temperature of 1650 DEG -2300 DEG F.  Specified molybdenum alloys contain 0,1-5% of one or more of titanium, tungsten, zirconium and beryllium and, in one case 0,05% carbon.

Title: Improvements in gear changing control mechanism
IPC: F16H61/02
Filed: 1925-08-07
Abstract: 258,987. Carling, W. T. Aug. 7, 1925. Clutches, ratchet.-In control mechanism for constant-mesh change-speed gearing employing free-wheel clutches, there is provided locking- means therefor, such as a tooth engaging a notch or a movable stop, whereby the control mechanism is inoperable to effect a speed change while the driving-member of the selected clutch is running faster than the driven member. Such means is described in Specification 257,701, reference being made to Figs. 1 to 10 and to Fig. 15 thereof. Fig. 5 shows a modification of one of the prior arrangements, according to which the pawlmesh 3 is not constantly subject to frictional drag, but is turned by the operating-collar 6 when a lug 6d thereon passes into contact with a driving- shaft collar 1b after an initial sliding movement of the, operating-collar 6, permitted by increased width of the notch 6b. In another modification, a tangential locking-bolt 2f, Fig. 6, slidably carried in lugs 2g on the driven wheel 2, is in frictional engagement with a driving-shaft collar 1b and. while the shaft 1 is running faster than the wheel, engages by its tooth 2h a notch in a finger 6e on the operating collar 6. In this position, a hooked lug 6a on the collar 6 engages the shorter limb of an L-shaped slot 3b in the frictionally-displaceable pawl-mask 3, so holding the clutch pawls out of action. On sufficiently retarding the shaft 1, the bolt 2f slides to bring its tooth 2h out of the notch, and the lug 6a can be moved by the collar 6 into the circumferential part of the slot 3b, so that, on accelerating the shaft 1, the mask 3 is carried round to permit engagement of the pawls. Specifications 194,152 and 234,238 also are referred to. The Provisional Specification describes a form with the driven member mounted on a shaft and with an inversion of the locking-mechanism, and refers also to Specifications 215,864, 225,322, and 249,964.

Abstract: 1,140,811. Hydroxy-containing aromatic phosphates and phosphites. J. R. GEIGY A.G. 1 May, 1967 [2 May, 1966], No. 19992/67. Heading C2C. [Also in Divisions C3 and C5] The invention comprises phosphites and phosphates of the general formula wherein is 0 or 1, R 1  is C 1 -C 18  alkyl, C 5  or C 6  cycloalkyl or C 7  to C 9  aralkyl, and R 2  is hydrogen or is a radical as defined for R 1 . The phosphates (i.e. x = 1) may be obtained by reacting an appropriately substituted hydroquinone with a stoichiometrically equivalent amount of a phosphorus oxyhalide e.g. POCl 3 , preferably by refluxing the reactants in an inert organic diluent, e.g. xylene, benzene, toluene, or heptane, or other higher boiling hydrocarbon. A basic catalyst e.g. magnesium oxide may also be present or magnesium chloride, iodine or U.V. light may be used, also the reaction may be carried out under a slow stream of nitrogen with collection of the hydrogen halide byproduct in sodium hydroxide solution. In another method an alkali metal derivative of the substituted hydroquine is reacted with a phosphorus oxyhalide. The phosphites (x = 0) may be obtained by reacting an appropriately substituted hydroquinone with a stoichiometrically equivalent amount of a phosphorus trihalide, e.g. PCl 3 , the reaction being facilitated by use of a basic catalyst or acid acceptor, e.g. pyridine, dimethylaniline, 2,6-lutidine or quinoline. A hydrocarbon diluent, e.g. benzene, toluene, xylene or heptane may also be present. The preferred products are those in which one or both of R 1  and R 2  is a bulky group e.g. tbutyl or t-octyl. The products are useful in the stabilization of organic material normally subject to deterioration caused by oxidation, heat or light and among the examples given is one for the stabilization of stearic acid by the addition thereto of tri (3,5-di-t-butyl-4-hydroxy-phenyl) phosphate.

Title: A process for sweetening sour hydrocarbon distillates and sweetening agents therefor
IPC: F02B3/06
Filed: 1960-06-09
Abstract: Hydrocarbon distillates, e.g. naphthas, light and heavy raw gasoline fractions, raw kerosene, diesel fuel, jet fuel, stove oils, furnace oils, and light gas oil fractions, are sweetened by contact in the presence of oxygen with a composition comprising by weight (a) 99,9-10 parts of a phenylene diamine which is a known sweetening agent, and (b) 0,1-90 parts of guanidine and/or a substituted guanidine in which there are 1-5 substituents which may be hydrocarbon radicals, oxahydrocarbon radicals in which the oxygen atoms are ether oxygen atoms, and azohydrocarbon radicals in which the nitrogen atoms are tertiary amino nitrogen atoms, each of the substituents containing 1-18 carbon atoms. Many examples of suitable compounds (a) and (b) are specified, but for (a) it is preferred to use an N:N1-dialkyl phenylene diamine having 1-12 carbon atoms in each alkyl group, N:N1-di-sec. butyl-p-phenylene diamine being especially suitable, while for (b) 1:1:3-trimethylguanidine and 1:1:3:3-tetramethylguanidine are preferred.  (a) is generally used in amounts of 1-50, preferably 2-20, lbs. per bbl. of distillate and (b) in amounts of 0,05-10, preferably 0,5-5, lbs. per bbl. of distillate. The composition may either be used directly as a mixture, or as a solution in, for example, benzene, toluene, kerosene, ethanol, isopropanol, acetone or methyl ethyl ketone.  Alternatively, the guanidine may be employed in the form of a salt, in which case the caustic normally employed in the process should be sufficient to neutralize the acid component of the guanidinium salt.  In a preferred embodiment, the sour hydrocarbon is mixed with 0,1-1% by volume of a 5-30% aqueous solution of an alkali metal hydroxide in the presence of air, in addition to the diamine (a) and the guanidine (b).  If required, alkanols, glycols, ether alcohols, alkanolamines, solutizers such as potassium isobutyrate, alkylphenols such as the cresols, polyhydroxy aromatic compounds such as tannic acid, or petroleum acids such as naphthenic acids may be incorporated in the aqueous alkaline solution.
