Filed: 1929-07-15
Abstract: 338,575. Glover, W. S. C. July 15, 1929. Motor or power units.-In transportable machines having self-contained power-units normally used for propulsion, such as motor lawn-mowers, cultivators, motor cars, and motor cycles, means are provided for temporarily attaching an accessory device, such as a waterpump, vacuum cleaner, chaff cleaner, or circular saw, to the main machine and for driving it from the power-unit when the machine is stationary. The accessory device, may be secured by readilydetachable means directly to the frame of a mower or, in general, to a base-plate or bracket mounted, preferably adjustably, on the machine. A base-plate 1, having legs 2 to clip over the axle 4 of a motor lawn-mower, is provided with studs 16 to engage keyhole-slots in the base 20 of the interchangeable accessory device, shown as a pump 18, the device being locked by a bolt &c. engaging a hole 17. A shaft 24, driven by the motor 25, is provided with a pulley 23, the, pump pulley 21 being driven by a belt 22, which is tensioned by rocking the base-plate 1 by an adjustable screwed stay 8, 11 secured to a framemember 13. The belt-tension may alternatively be varied for starting and stopping by a jockeypulley on a pivoted arm coacting with a locking- quadrant, Fig. 4 (not shown), the base-plate being non-adjustable. For chain-drives, the driving-sprocket is connected to the shaft 24 by a friction clutch, Fig. 5 (not shown). The baseplate &c. may be dispensed with and the machine frame be provided with spaced dovetailed projections 36, Fig. 6, adapted to enter lateral gaps and engage dovetailed recesses in the accessory device, which is locked by a screw 37. The Provisional Specification describes arrangements in which the accessory device is driven by gearwheels or by direct clutch-engagement with a countershaft existing or provided on the machine or detachable base-plate, and states that the invention is applicable to portable pumps and saws.

Title: Improvements relating to the manufacture of cast iron
IPC: C22C37/04
Filed: 1946-07-22
Abstract: A grey cast iron, having its carbon content predominantly in the nodular form, contains 0.02-0.5 per cent of cerium (other than any present as cerium sulphide), less than 0.02 per cent of sulphur and less than 0.5 per cent by weight of phosphorus.  The cast iron may be hypereutectic or hypoeutectic with respect to carbon, i.e. the percentage carbon content is greater or less respectively than 4.3- 1/3 (P + Si) where P and Si represent the percentage of phosphorus and silicon in the cast iron.  Thus the cast iron may have the following composition: Ce (other than that present as cerium sulphide) 0.02-0.5 per cent, Si 2.30-7.0 per cent, Mn 0.5-7.0 per cent, Cr 0-4.0 per cent.  Mo 0-2.0 per cent, V 0-2.0 per cent, S 0-0.02 per cent, P 0-0.5 per cent, C 2.0-4.4 per cent, Fe, together with the usual impurities and incidental elements, the remainder. The silicon may be below 2.3, in which case copper and/or nickel should be present in total amount at least three times as great as the deficit of silicon from 2.3 per cent.  Nickel may be present in the hypoeutectic cast irons in proportions of 10-40 per cent.  The molten cast iron should preferably be desulphurized before the addition of cerium.  Cerium may be added in the form of cerium metal, mischmetall, or any alloy in which cerium is the main component, magnesium preferably being absent.  After adding the cerium there may be added graphitizing, nucleating or deoxidizing additions, namely, ferrosilicon, silicon, aluminium, graphite, or alloys containing 40-99 per cent of silicon and up to 50 per cent of aluminium, manganese, titanium or zirconium.

Title: Process for the preparation of a nitrogen substituted oxazolidine, the nitrogen atomof which is linked to the sulphur atom of an organic sulphonic acid radical
Filed: 1953-08-12
Abstract: Oxazolidines of the formula <FORM:0740583/IV(a)/1> where R is alkyl, aryl, aralkyl or cycloalkyl, R1 is hydrogen or a hydrocarbon radical and R11 is hydrogen or an aliphatic hydrocarbon radical (the hydrocarbon radicals being optionally substituted or interrupted by other atoms) are made by reacting N-(b -hydroxyalkyl)-sulphonamides with aliphatic aldehydes (or substances generating them) in the presence of gaseous hydrogen halide.  A chloromethyl ether is probably an intermediate.  The reaction is preferably carried out in an inert anhydrous organic solvent such as benzene.  The products regenerate the aldehyde R11-CHO in acid solution and thus show pesticidal and disinfectant properties.  Examples show the production of the following oxazolidines: 3-p-toluenesulphonyl, 3-p-chlorobenzenesulphonyl, 3-dodecanesulphonyl, 3 - dodecanesulphonyl - 5 - methylol, 3 - p - nitrobenzenesulphonyl, 3 - alkylbenzenesulphonyl where the alkyl is of average chain length C13, and 2-methyl-3-p-toluenesulphonyl.  The preferred reactant is paraformaldehyde but there may also be used formaldehyde itself, trioxymethylene, hexamethylene tetramine or acetaldehyde.  Other specified sulphonamide reactants are N-(b :g -dihydroxypropyl) - dodecylbenzene - sulphonamide and N:N1-di-(b -hydroxyethyl)-benzene-1:3-disulphonamide.

Patent GB-602273-A (GB)
Title: Improvements in or relating to fractional distillation
IPC: C07C7/06
Filed: 1945-08-29
Abstract: Cyclic nitrogen bases and hydrocarbons are separated from their respective azeotropes with fatty acids by subjecting the azeotropes to fractional distillation in the presence, in the former case, of hydrocarbons forming with the acids, azeotropes having a lower boiling point than the base-acid azeotrope, and in the latter case, of cyclic nitrogen bases giving with the acids, azeotropes boiling at a higher temperature than the hydrocarbon-acid azeotrope.  The hydrocarbons and bases should not form azeotropes with each other. The process is particularly applicable to the separation of fatty acids from their azeotropes with hydrocarbons or organic bases, which are obtained when the fatty acids have been used as azeotrope-formers in the fractionation of hydrocarbon mixtures or of organic base mixtures. In an example, an equal weight of toluene was added to the b -picoline-acetic acid azeotrope and the mixture was submitted to batchwise fractional distillation in a 50 plate column at barometric pressure.  A small forecut containing water was taken off first, and then the toluene-acetic acid azeotrope.  A small fraction consisting principally of toluene distilled next, and finally, substantially pure b -picoline.  In another example, the toluene-acetic acid azeotrope was placed in a reservoir at the top of a 50 plate column and an equal weight of crude picoline (boiling range 140-145 DEG ) containing b - and g -picoline and 2 : 6-lutidine, was placed in the still.  The contents of the still were boiled and the toluene-acetic acid mixture allowed to drop into the top of the column.  The vapour from the top of the column was condensed and collected in the reservoir.  The liquid in the reservoir was gradually reduced in volume to that of the toluene in the azeotrope initially placed in the reservoir, and eventually it consisted substantially of toluene, while the still contained base and acetic acid.  Specification 585,108 is referred to.

Abstract: 1,181,343. Resolving a mixture of organic chlorophosphines. KNAPSACK A.G. 10 May, 1968 [11 May, 1967], No. 22316/68. Heading C2C. A mixture of lower alkyl mono- and dichlorophosphines having from 1 to 3 carbon atoms, is resolved by saturating the mixture with hydrogen chloride, separating the resulting two liquid phases I and II, and isolating the dichlorophosphine from the lighter phase I and the monochlorophosphine from the heavier phase II by distillation. The monochlorophosphine-containing phase II may be further purified before distillation by saturating once again with hydrogen chloride and extracting once or twice with an inert solvent to give phases IIIa and IVa, and in the latter case, IIIb and IVb. The lighter phases IIIa and IIIb may then be added to phase I for distillation. The heavier phases IVa and IVb are mixed again with the inert solvent and boiled until the hydrogen chloride ceases to be evolved. Thereafter, the mixture is fractionally distilled to obtain two further liquid phases V and VI, the former being rejected or combined with the phases IVa and IVb, and the latter being distilled to obtain the pure monochlorophosphine. Inert solvents may be aromatic, aliphatic or cycloaliphatic hydrocarbons or halogenated hydrocarbons which are miscible with dichlorophosphine but which do not dissolve the HCl-addition product of the monochlorophosphine, e.g. toluene, xylene, cumene, heavy gasoline, decalin and chlorobenzene.
