Filed: 1944-08-31
Abstract: An insecticidal concentrate consists of a suspension of small particles of solid dichlordiphenyltrichlorethane in a concentrated aqueous solution of a wetting agent.  The preparation is diluted with water before use.  According to an example, Teepol X (Registered Trade Mark), which is an aqueous solution of higher alkyl sulphates, is evaporated until it begins to gel. Dichlordiphenyltrichlorethane is then added and the heating is continued until the added compound has melted.  The two substances are mixed thoroughly and the mixture is allowed to cool.  Water is stirred into the resulting opaque gel to produce a product containing 12.5 per cent. of dichlordiphenyltrichlorethane. Specification 547,874 is referred to.

Abstract: 549,330. Cans. CROWN CORK & SEAL CO., Inc. Nov. 21, 1940, No. 16753. Convention date. May 13, 1940. [Class 66] [Also in Group-XXII] Metal containers for beer &c. are formed with integral conical top and cylindrical neck portions formed by drawing from cup-shaped blanks, the neck portions terminating in hollow mouth beads adapted to receive crown caps or other closures. The body part 10, Fig. 1, is integral with the top, a.bottom 23 being seamed or welded thereto for instance as at 26. The integral top and body portions are drawn in progressively narrowing forms and so that the neck and top are least subjected to the drawing action, the metal thus remaining in a suitable condition for the subsequent formation of the mouth bead, the remaining portion of the top and the body wall being so formed that the thickness of the metal increases from the neck 12 towards the open end. After the necking and punching operation, Fig. 12, and the preliminary curling at 38, Fig. 13, of the metal above the neck, and the flanging at 25 of the body end, the mouth bead is formed in a curling die as shown in Fig. 17, the preliminary curl 38 being flattened to form a fold or hem 40 ; after formation the bead is flattened and closed to the form shown in Fig. 1, the hem 40 bearing against the inclined wall portion 15. The conical part 11 is formed with a series of annular grooves 41, Fig. 2, separated by flat portions. Specifications 488,427, 488,610, 488,628, 510,370 and 546,489, [Group XXII], are referred to. The Specification as open to inspection under Sect. 91 describes also constructions in which the body portion and the base, which may be integral therewith, are formed separate from the neck and the conical shoulder which is not necessarily grooved and ribbed, and also in which the mouth bead or hem projects inwardly. This subject-matter does not appear in the Specification as' accepted.

In a two-stroke engine having fuel injection and at least one free running turbo-supercharger 20, means are provided for adjusting the pre-exhaust angle which are actuated in dependence on the pressure in a fuel pipe 46 between a positive-displacement fuel feed pump 42 and a fuel injection pump 47. A valve 12 controls exhaust gas flow to passage 11 leading to gas turbine 20 which drives compressor 9. Camshaft 23 is driven through gearing 24 ... 29 of which gear-wheels 27, 28 are connected together and freely rotatable on journal 30, mounted on lever 31 which is moved by piston rod 32 attached to piston 33 to pivot aboutcam-shaft 23.Thespring- loaded piston 33 slides in cylinder 35 away from stop 19 under pressure fed via pipe 36. Pump 42 is driven by gearing 24, 25, 43, 44, 45 and feeds fuel through pipe 46 to fuel injection pump 47 which delivers some fuel to injector 50, excess fuel being returned to tank 40 through pipe 52 containing a throttle 51. The pressure in pipe 36 is dependent on the engine speed and inversely dependent on the amount of fuel injected per stroke and if pressure in pipe 36 is low spring 34 holds piston against stop 19. With pressure rise in pipe 36, piston 33 is lifted and moves lever 31 in the clockwise direction, thus advancing the opening of the exhaust valve.

Patent GB-486821-A (GB)
Title: Process of separating lower alkylamines
Filed: 1937-06-17
Abstract: The separation of primary, secondary, and tertiary alkylamines containing not more than 3 carbon atoms is effected by treating a mixture of their hydrohalides with alkali stoichiometrically equivalent to the alkylamines present which have dissociation constants smaller than 60 per cent of that of the secondary amine, and separating the liberated bases.  The alkali must be sufficiently basic to displace the said amines having small dissociation constants.  Alkali and alkaline earth metal oxides, hydroxides, and carbonates may be used or alkylamines of the necessary basicity.  A mixture of methylamine hydrohalides may be treated with alkali equivalent to the trimethylamine present which can then be boiled out.  Mixtures of the ethylamine or propylamine salts can be treated with alkali equivalent to both the primary and tertiary amines which are then expelled.  Dimethylamine may be used to displace trimethylamine, and diethylamine to displace mono- and triethylamines.  If free hydrogen halide or ammonium salts are present, additional alkali equivalent thereto must be added.  As an initial step, partial separation with chloroform or other selective solvent may be employed.  The process is applicable to mixtures of only two amines.  In examples: (1) a solution containing the three methylamine hydrochlorides and ammonium chloride is treated with caustic soda to liberate trimethylamine and ammonia which are distilled off.  The solution is evaporated to dryness and extracted with chloroform to dissolve the dimethylamine hydrochloride; (2) a solution containing the three ethylamines and excess HCl is treated with sufficient caustic potash to neutralize the free acid and liberate mono-and triethylamines which are distilled.  Additional caustic potash is added and the diethylamine distilled; (3) a mixture of methylamine hydrochlorides is treated with chloroform to extract the di- and trimethylamine salts.  The solution is evaporated to dryness, the residue dissolved in water, and sodium carbonate added to liberate trimethylamine.  This is distilled and the remaining dimethylamine salt extracted with alcohol. Specification 486,822 is referred to.
