Title: Improvements relating to explosive bombs, projectiles, and the like
IPC: F42B12/20
Filed: 1939-05-07
Abstract: 531,678. Bombs; projectiles. KRAMERS, B. May 7, 1939, Nos. 32277/38. [Class 9 (i)] An explosive bomb or projectile comprises a casing housing separate volumes of gases under different pressures, the gases being such as to form an explosive charge when mixed, air-pressure actuated means for ensuring the mixing of the gases during the flight of the bomb or projectile, and means for igniting the mixture on impact. In the bomb shown, a cylinder 13 of oxygen is supported within the bomb by means of perforated tubular holders 14, 16 and 17, 18. The space between the cylinder and the casing is filled with acetylene at a lower pressure than the oxygen, through a valve 38. The front portion 19 of the bomb carries a percussion detonater 33 adapted to be fired on impact by an inertia ring 35 normally held away by a spring 36. The shaft 23 of a propeller 24 has a screw-threaded portion 25 engaging a thread 26. In flight, the rotation of the shaft 23 frees it from the thread 26, and the shaft is then moved axially by a spring 39, so that a drill or the like 21 destroys the seal 27 of the oxygen cylinder 13, thus allowing the gases to form an explosive mixture. Alternatively, the seal may be broken by a piercer on a spring-pressed lever, one arm of which is normally engaged by the shaft 23, and freed by the axial movement of the shaft in flight. The bomb or projectile may carry also an incendiary charge, and the gases may be stored in liquefied state. Sheet-metal stampings may also be used to form a shrapnel charge. Instead of the seal 27, a valve may be used, and the gases may each be stored in a separate valved container. According to the Provisional Specification, the igniter 33 may be pyrophoric in action.

Title: Improvements in carburetters
IPC: F02M7/133
Filed: 1953-11-23
Abstract: 739,034. Carburetters. GENERAL MOTORS CORPORATION. Nov. 23, 1953 [Dec. 13, 1952], No. 32363/53. Class 7(3). In a carburetter having a main fuel passage and an auxiliary fuel passage under the control of a check valve movable by and in response to changes of pressure in the intake manifold posterior to the throttle valve the check valve is movable by a member carried by a piston subject to this pressure the member having a passage through which a predetermined proportion of air passes to mix with the fuel passing through the auxiliary fuel passage when the check valve is open. As shown an auxiliary passage 40 the flow through which is controlled by a valve 43 connects with a main fuel passage 17. The valve 43 is controlled by a tube 48 carried by a piston 51 actuated by the suction on the downstream side of a throttle valve 6. When the valve is opened air is admitted to the fuel through a passage 53 the tube 48 and a notch 60 at intermediate speeds with the throttle valve partly open the piston 51 is raised but as the throttle valve is moved towards wide open position the piston drops to increase the fuel supply. The position of the tube 48 to the piston or the length of the tube can be varied. The size of the passage 53 can be changed. The tube can be a press fit in a bore 52. The fuel chamber is vented through a tube 33. The choke and throttle valves are interconnected by means of a lever 34. Instead of employing the passage 53 an orifice may be formed in the wall of the tube 48 adjacent the upper end and by adopting a different size and shape of such orifice the admission of air and the amount of fuel supplied can be modified.

Title: Improvements in the manufacture and production of vat dyestuffs of the n-dihydro-1.2.2.1-anthraquinoneazine series which are fast to chlorine
IPC: C09B5/48
Filed: 1929-10-24
Abstract: Indanthrone dyes.-Dyestuffs fast to chlorine are obtained by fractional precipitation of the dyes obtainable by the action of formaldehyde or agents supplying the same, such as paraformaldehyde, methylal and glycollic acid, on impure N-dihydro-1 : 2 : 21 : 11-anthraquinoneazine, from their solution in conc. sulphuric acid, by dilution to not less than 70 per cent strength, or by extracting from the said condensation products, components not fast to chlorine by means of dilute sulphuric acid of at least 70 per cent strength. The purification may be effected by adding water or dilute sulphuric acid in the requisite amount to a solution of the condensation product in sulphuric acid.  Products equally fast to chlorine are obtained by condensing formaldehyde, or agents supplying it, with pure N-di-hydro-1 : 2 : 21 : 11-anthraquinoneazine obtained according to Specifications 113,489, 184,193, and 320,397, [all in Class 2 (iii), Dyes, &c.].  The dyes may be subsequently purified, or treated with alkalis, oxidizing or halogenating agents and are greenish blue. According to examples, (i) water is added to a solution of the dye obtained by the action of paraformaldehyde on commercial Indanthrone Blue RS, and the precipitated dye separated; (2) pure indanthrone is treated with paraformaldehyde in concentrated sulphuric acid, and diluted; (3) pure indanthrone is treated in concentrates sulphuric acid with a different proportion of paraformaldehyde diluted and the dye separated; thereafter the product is treated with varying proportions of sulphuryl chloride, or with caustic potash, to give purer products of equally good fastness to chlorine; (4) pure indanthrone in concentrated sulphuric acid is treated with formaldehyde solution and worked up as in example 2; (5) pure indanthrone in concentrated sulphuric acid is treated with paraformaldehyde followed by manganese dioxide, to give the azure on separation, and this product may be reduced to the N-dihydroazine, and further, chlorinated as above; (6) a product similar to that of example 4 is obtained by treating pure indanthrone with paraformaldehyde and concentrated sulphuric acid; (7) a product obtained by treating pure indanthrone with glycollic acid in concentrated sulphuric acid is further chlorinated with chlorine; (8) pure indanthrone is treated with a small quantity of paraformaldehyde in concentrated sulphuric acid, to give a slightly different product. Specification 20527/04, [Class 2, Acids and salts, Organic &c.], also is referred to.
