Abstract: 535,777. Lubricating-compositions. STANDARD OIL DEVELOPMENT CO. Sept. 21, 1939, Nos. 26361 and 26362. Convention dates, Oct. 14, 1938 and Sept. 1, 1939. [Class 91] A lubricating-composition for use in internal combustion engines comprises a mineral lubricating oil and small amounts of salts or soaps of at least two metals selected from the groups consisting of (1) aluminium, (2) nickel, and (3) a group consisting of the alkaline earth metals and magnesium, such soaps being salts of the following acids and analogous compounds :- saturated fatty acids melting below 50C., mixed acids from commercial fats containing 10-30 per cent. of unsaturated acids, unsaturated acids such as oleic and erucic acids, naphthenic acids, acids produced by low temperature oxidation of paraffin wax, sweater oil, solvent extracted oils or hydrogenated oils, phenols and thiophenols, alkylated and sulphide derivatives of phenols, thiophenols and mixed oxy-and thio-phenols, alcohols and thioalcohols, carbamic and thiocarbamic acids, xanthogen and thioxanthogen, enolic compounds, and compounds containing acyl, thioacyl, phosphyl and thiophosphyl radicles, the amount of each type of salt present being at least one-tenth of the total salt present. The salt or soap is preferably prepared by co-precipitation of two salts by reacting alkali metal salts with water-soluble salts of one specified metal. The total amount of soap present ranges from 0.1 to 3.5 per cent. and is preferably between 0.2 and 1.5 per cent. A mutual solvent of the oil and the salts or soaps, such as stearic acid, stearyl alcohol, dibutyl phthalate and tricresyl phosphate, may be added to the mixture. Lists of suitable salts or soaps for making the mixtures are given. In examples (1) the effect of adding a mixture of the aluminium and calcium soap of sweater oil acids to a naphthenic lubricating distillate is compared with the effect of adding the soaps singly, (2) the effect of adding a mixture of the nickel and barium salts of tertiary amyl phenol sulphide is compared with the effect of adding the salts singly, and (3) a mixture of the nickel salt of tertiary amyl phenol sulphide and the calcium salt of the enol form of the hexyl ester of acetoacetic acid is added to a lubricating oil. Specification 469,889 is referred to.

Title: Improvements in or relating to nuclear reactors
Inventor: TAYLOR PETER ANTHONY
IPC: G21C1/00
Filed: 1964-07-02
Abstract: 1,072,513. Reactors. BABCOCK & WILCOX Ltd. July 1, 1965 [July 2, 1964], No. 27295/64. Heading G6C. In a reactor having a core 12 within a pressure vessel 14 primary gas coolant from a collector 18 passes to a plurality of heat exchangers 16 through ducts 19, the coolant leaving the heat exchangers through valves 22 and entering a plenum 20. The plenum 20 is sealed from the collector 18 by a member 39 and is divided by a wall 41 into an outer chamber 38 and an inner chamber 40. Blowers 42 transfer the coolant from chamber 38 to chamber 40 whence it flows through an annular passage 17A back to the core 12. Inlet and outlet means 16<SP>1</SP>, 16<SP>11</SP> form a path for the secondary coolant flow through each heat exchanger 16. Should this secondary coolant flow through one of the heat exchangers be stopped the associated primary coolant valve 22 is closed, but nevertheless leakage through the valve may overheat the exchanger and cause damage. To prevent this damage the heat exchanger is cooled by a flow of coolant from the chamber 40, this flow being conducted by a conduit 44 connected to the primary coolant flow path of the heat exchanger on the upstream side of the valve 22. The conduit 44 is controlled by a valve operating in conjunction with the valve 22 (Figs. 2, 3, not shown) whereby when the valve 22 is closed the conduit valve is opened and vice versa. The coolant from chamber 40 flows into the heat exchanger because the pressure in the chamber is considerably higher than that in the collector 18.

Patent GB-1009311-A (GB)
Title: Bauxite agglomerates and method of preparing same
IPC: C04B28/34
Filed: 1964-07-02
Abstract: Bauxite agglomerates, consisting of activated bauxite fines the surface of which is cemented together by the combination of alumina and aluminium phosphate each of which has been formed by reaction in situ of part of the aluminium in the fines with the combination of phosphoric and sulphuric acids followed by thermal elimination of sulphate, may be prepared by mixing bauxite fines with a mixture of sulphuric and phosphoric acids, forming the mixture into agglomerates, aging the agglomerates at a temperature and for a time sufficient for the acids to react with aluminium in the fines and calcining the aged agglomerates at a temperature and for a time sufficient to eliminate sulphate. Prior to aging, the mixture of fines, which may be of calcined bauxite, and acids, which may be in aqueous solution, may be mixed to form a plastic extrudable mass which is extruded to form pellets which are aged and calcined, preferably by heating to a temperature of from 900 DEG  to 1800 DEG F.  The mixture may be in the form of a slurry to which sufficient bauxite is added to form a mass of plastic extrudable consistency. Preferably, 50 to 100 parts by weight of acid solution (calculated as 100% acid) are present per 100 parts by weight of volatile-free bauxite.  The agglomerates may be impregnated with a catalytically active material, for example a metal oxide oxidation catalyst such as copper oxide; such impregnation may be with a solution of a thermally decomposable metal salt, for example a copper salt such as cupric nitrate, sulphate or acetate, or cuprous or cupric chromite, or a salt of zirconium, titanium, chromium, vanadium, molybdenum or potassium, followed by heating at a temperature and for a time sufficient to decompose the salt and form the metal oxide oxidation catalyst.  Preferably, the amount of copper salt gives on thermal decomposition about 10% by weight of oxide in the catalyst. The catalytically active material supported on activated bauxite agglomerates may be adapted for the oxidation of fuel hydrocarbons and carbon monoxide in the exhaust of an internal combustion engine.

Abstract: 882,988. Radio receiving systems. STANDARD TELEPHONES & CABLES Ltd. Aug. 11, 1959, No. 27374/59. Class 40(5). In a space diversity receiving arrangement, two antennae 1, 2 feed, by way of a combiner. 15, a receiver having only one input circuit, and means controlled by the receiver automatically bring the two antennae into phase before they are delivered to the input of the receiver. The Specification describes such a system applied to frequency division multiplex transmission, channel separation filters 4, 8 to 5, 9 being provided in the antennae outputs. The signals from antenna 2 are phase modulated at a low frequency, e.g. 35 c.p.s. by oscillator 12 and modulator 11, the first channel signal being fed to one input of a hybrid junction 15 through adjustable phaseshifter 16. When the inputs to junction 15 are' out of phase the input to frequency changer 17 is amplitude modulated at the low frequency and this modulation is recovered by rectifier 19. Phase detector 20 has a unidirectional output whose magnitude is proportional to the amplitude of the modulation component from rectifier 19 and whose sign depends on the sign of the phase difference between the inputs to junction 15. Phase detector 20 is connected to a chopper device 21 producing a square-wave output whose amplitude is proportional to. the output of detector 20 and having the same frequency as source 22, e.g. 50 c.p.s. Chopper 21 and source 22 control a motor driving phaseshifter 16 to maintain the desired phase coincidence between the inputs to junction 15. Phase adjuster 14 is adjusted with a given output from rectifier 19 until the maximum output of detector 20 is obtained, the adjustment serving for all channels. Units 15-21 and 23 are provided between each pair of channel separation filters, source 22 and oscillator 12 serving all the channels. Specification 734,545 is referred to.
