Title: Improvements in or relating to clutches
IPC: F02N15/08
Filed: 1920-07-10
Abstract: 148,514. Soc. Anon. des Etablissements L. Bleriot. Feb. 4, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Toothed and friction gearing.-Relates to disconnectible friction and toothed gearing, particularly applicable to engine starting gear of the kind described in Specification 128,900. In the form shown, an electrically driven shaft b carries a friction wheel b<1> with several taper flanges engaging with a similar wheel c<1> secured to a shaft c loose in an arm a<1> free to rotate around the axis of the shaft b within limits provided by stops h<1>, h<2>. When the shaft b rotates, the inertia of the parts causes the arm a<1> to swing so that the wheel c<1> engages a wheel d, split, for convenience of assembly and secured on the engine shaft. When the engine starts and the resistance ceases, the arm automatically returns and disengages the gearing. To render the action more certain, brakes may be applied between the arm a<1> and the shaft b or the shaft c or both. In the form shown, a cork brake-block c<3> is carried on a spring-controlled lever e', but one or more blocks may be acted on directly by one or more springs. To remove the brakes when the engine starts, a centrifugally operated brake may be used, or the brake may be actuated by two magnetic coils, one of which is arranged in a shunt. to or in series with the electromotor, and may be brought into action slightly before the latter to apply the brake, the other being arranged in a shunt to the armature and effectively opposing the first coil only when the armature attains a predetermined speed. The braking-effect may be obtained by tightening the bearings or by setting them askew. To prevent jamming of the wheel c' between the wheels b<1>, d, the motor may be carried on a pivot f so that it may swing against the action of a spring g. The friction wheels may be replaced by toothed wheels, which may have very pointed teeth or may be so arranged as to dispense with the need of the stop h<1>. Cylindrical friction rollers may be used in combination with thetoothed wheels.

Title: Improvements in or relating to soldering fluxes
IPC: B23K35/36
Filed: 1947-07-30
Abstract: The activity of a soldering flux containing at least one heavy metal fluoborate and at least one acidic inorganic non-metallic boro-fluoride compound and at least one aliphatic polyamine or aliphatic amino alcohol is increased by introducing an amount of ammonia which is at least 0.5 per cent but preferably not more than 3 per cent by weight of the total flux, or an equivalent weight of decomposable ammonium salt, into the flux and thereafter heating the flux above 50 DEG C, but below the decomposition temperature of any portion of the amine component until the desired increase in activity is effected, the heating period being in general between 3 and 30 minutes per pound of flux.  The flux which may contain other ingredients, e.g. plasticizers, is intended for use in soft soldering of aluminium and its alloys. Specified heavy metal fluoborates are those of cadmium, zinc, tin and lead.  The acidic inorganic non-metallic boro-fluoridic compounds include BF3, hydrofluoboric acid, dihydroxy fluoboric acid and like acids; these may be present in the proportion of one or more moles or fraction of a mole per mole amine.  The metal fluoborates are normally present in amounts up to 25 per cent by weight of the flux.  The activating ammonia may be added to the prepared flux or supplied with the components making up the flux.  When a decomposable ammonium salt is used it must be decomposable at the activating temperature and must not yield substances interfering with the action of the flux.  The ammonia may be introduced by using the acidic inorganic non-metallic boro-fluoride compound in the form of its ammonium salt.  Preferably, the ammonia is introduced in combination with boron and fluorine as in ammonium fluoborate, a heavy metal salt such as cadmium fluoborate hexammine, and in such mixtures as NH4F or NH4HF2 with boric acid, boric oxide, an organic borate or boron-tri-fluoride-ammonia. Examples are given illustrating the activation of fluxes prepared from triethanolamine, hydroxyethyl ethylene diamine and tetraethylene pentamine respectively and cadmium fluoborate and hydrofluoboric acid, the ammonia being introduced as the gas or in combination with the acid or the fluoborate.  The activities of some of these are compared with those of similar fluxes which are either not ammoniated or are ammoniated but not heated.  Specifications 684,081 and 684,082 are referred to.

Filed: 1946-07-10
Abstract: <PICT:0631874/IV (b)/1> The alkylation of benzene with normally gaseous olefins in the presence of an aluminium halide is effected continuously in a plate-type column at the boiling temperature of the mixture of reactants and products, the catalyst being removed prior to exhaustion and replaced by fresh catalyst, monoalkyl product being continuously withdrawn, and unreacted benzene separated and recycled. The apparatus and method of operation may be that described in Specification 627,573.  Benzene and aluminium chloride-hydrocarbon complex are fed by lines a, C respectively to column B, olefin being introduced by pipe d and HCl by pipe f. Cooler c separates hydrocarbons from the exit gas for recycle by pipe h.  In decanter D catalyst separates and is recycled through pipe C while hydrocarbons are water-washed in column F and thence fed by line l to fractionator G provided with condenser H. Benzene-water azeotrope condenses in H, is separated in decanter I, and benzene recycled by lines m and n. Alkylated products are fractionated in J, monoalkyl benzene being condensed in K while polyalkyl derivatives are recycled through pipes r, t.  Catalyst is removed by pipe u, and fresh catalyst obtained by passing benzene over aluminium chloride in column L is admitted by pipe v. By varying the pressure, the reaction temperature in column B can be adjusted.  In a modification, Fig. 2 (not shown), decantation of catalyst from hydrocarbons is effected in a cup inside the lower part of column B, the lower layer then being taken, if desired, to an auxiliary decanter.

Patent GB-815983-A (GB)
Title: Process for the manufacture of aliphatic dicarboxylic acids
IPC: C07C55/02
Filed: 1955-07-20
Abstract: Aliphatic dicarboxylic acids are manufactured by heating a -trichloro-o -chloroalkanes with a metal cyanide, e.g. sodium cyanide, in the presence of a glycol ether as solvent to form the corresponding a -trichloro-o -cyanoalkanes, and the latter are hydrolysed in one operation to the corresponding dicarboxylic acids by heating in sulphuric acid containing a quantity of water at least sufficient to hydrolyse the trichloromethyl and cyano groups.  The glycol ether solvent may be, for example, ethylene glycol monomethyl ether or ethylene glycol monoethyl ether.  The chloroalkane and metal cyanide are advantageously heated under reflux in the solvent with vigorous stirring, with the addition of a trace of iodine as catalyst.  After cooling the reaction mixture is filtered to remove the metal chloride, then washed and, after removing the solvent, the a -trichloro-o -cyano-alkane is obtained by distillation in vacuo. The latter may then be introduced dropwise into sulphuric acid of 70-95 per cent strength heated at 95 DEG  C., while stirring vigorously, whereby both the trichloromethyl and cyano groups are hydrolysed to carboxyl groups.  If the concentration of sulphuric acid is below 70 per cent a longer period of heating at 90 DEG  C. is required.  In examples: (1) a -trichloro-o -chloropentane is introduced dropwise into a vigorously stirred mixture of sodium cyanide, ethylene glycol monomethyl ether and a few crystals of iodine heated to 117 DEG  C. with refluxing, the temperature is maintained for 6 hours and after cooling, filtering and washing with ethylene chloride, a -trichloro-o -cyano pentane is distilled off in vacuo and then added dropwise to 93 per cent sulphuric acid and water at 96 DEG  C., stirred for 10 hours and worked up to recover adipic acid; (2) a -trichloro-o -chloroheptane is similarly converted to a -trichloro-o -cyanoheptane and the latter hydrolysed to suberic acid; (3) as in (1), a -trichloro-o -chlorononane is converted to a -trichloro-o  -cyanononane and the latter hydrolysed to sebacic acid. Specification 581,900, [Group IV], is referred to.
