Title: Manfuacture of amines
Filed: 1949-05-19
Abstract: Amines are prepared by the reduction of carboxylic acid amides with lithium aluminium hydride, preferably in the presence of an anhydrous inert organic solvent.  The amides may be aliphatic, alicyclic, aromatic, araliphatic or heterocyclic, and may be substituted, e.g. by a free or etherified hydroxyl group or another amide group (when the product will be a polyamine).  The amides may alternatively be cyclic as in lactams, e.g. 2-pyridones, in dicarboxylic acid imides, e.g. phthalimides and quinolinic acid imides.  The solvent is preferably ether, but may be tetrahydrofuran, butyl ether, or dioxan. In the examples: (1) N : N-diethylacetamide is reduced to triethylamine; (2) propionic acid ethylamide to ethylpropylamine; (3) a -ethylcrotonic acid amide to b -ethylbutylamine; (4) phenoxyacetamide to b -phenoxyethylamine; (5) 3 : 4 : 5-trimethoxybenzoic acid dimethylamide to N-(3 : 4 : 5-trimethoxybenzyl) dimethylamine; (6) phenylacetamide to b -phenylethylamine; (7) phthalimide to iso-indoline; (8) N-acetyldecahydroisoquinoline to the N-ethyl compound; (9) quin-olinic acid bisbenzylethylamide to 2 : 3-bis-(N-ethyl-N-benzylaminomethyl) pyridine; (10) isodihydrocarbostyril to 1 : 2 : 3 : 4-tetrahydroisoquinoline; (11) 9-phenanthryl carboxylic acid amide to 9-aminomethylphenanthrene; and (12) diphenylmethoxyacetic acid dimethylamide to b -dimethylaminoethylbenzhydryl ether.

IPC: F41A9/83
Filed: 1916-09-25
Abstract: 125,632. Fudge, R. C. Sept. 25, 1916. Cartridge magazines.-Relates to apparatus for charging machine-gun magazines, particularly those of the rotary-drum type as used in the Lewis gun, and to apparatus of the kind in which the cartridges are fed to the magazine by a guide which causes them to fall by gravity from the vertical to the horizontal position. According to the invention, the guide is of curved or arcuate form and has a fixed central block for retarding the bullet ends of the cartridges as they fall down the guide. The apparatus shown in Figs. 1 and 4 is adapted to receive a Lewis-gun magazine comprising a fixed centre a having a spiral groove c for guiding the bullet ends of the cartridges, and a rotary pan b in which the cartridges are accommodated between pins d. The magazine to be filled is keyed upon a pin x with the radial outlet from the slot c in line with the end of a tongue l on the apparatus, which tongue forms a continuation of the slot spiral. The cartridges are fed to the magazine by inserting the usual service clips vertically through a slot in the upper part of a guide m, the projection n stripping the cartridges from the clips when these are moved to the right. The cartridges pass down the guide m in a vertical position, and are brought to an horizontal position in the arcuate part of the guide by the contact of the bullet ends with a fixed block k. After traversing the lower arcuate portion of the guide under the influence of the tongue l, the cartridges pass into the radial compartments of the magazine as the pan is rotated. A spring- controlled pawl r prevents rotation of the magazine when the supply of cartridges ceases. Surplus cartridges are held up whilst the magazine is being changed, by pins p on a movable finger o.

[Class 9 (i)] In a rocket intended to be fired from a gun, the rocket charge 4 is in a thinwalled casing 3, Fig. 1, and provision is made to ensure a balance between the pressure inside and outside this casing when the gun is fired. The inside pressure may be derived by leakage from the external pressure or by internally generated gases. The driving band is situated in front of the rocket casing 3. The rocket charge may be built up of a number of separate cylinders, side by side, Fig. 3 (not shown). When a considerable rocket charge is required, it may be made in two separate lengths 4a, 4b, Fig. 7, of cordite separated by a perforated disc 5 to prevent damage to the charge by the shock of discharge. There may be a single central nozzle or several nozzles 11, Fig. 1, which may be parallel to the axis or may be inclined thereto to cause rotation. Or as in Fig. 7, there may be nozzles 28, 29 at the rear end and also nozzles 26 around the middle part of the rocket casing which may be in two parts 22, 23. The rate of burning of the rocket charge may be controlled by an adjustable spring-loaded valve such as 29. For cleaning the gases from unburnt _particles before they reach the nozzles, the gases are passed through diverting devices such as socket 7, Fig. 1, with axial inlet 8 and radial outlets 9, or a socket with an, internal baffle and an external spiral baffle, Fig. 5 (not shown), or a long central tube containing a spiral baffle, Fig. 6 (not shown).

Title: Process for the production of steel
IPC: C21C5/32
Filed: 1962-04-11
Abstract: In the production of steel from a solid charge, such as scrap or pig-iron, a part of the charge is melted, preferably in a hot-blast cupola, while the remainder is heated till it becomes pasty, either in the refining vessel or a separate heating vessel, by blowing with a burning mixture of oxygen-containing gas, which may be air, and a fuel such as oil, coke or gas.  The two parts of the charge are then combined, with the addition of necessary slag-forming ingredients and the charge heated to refining temperature by further blowing with the oxygen-fuel mixture, after which the bath is refined by top-blowing with oxygen. Heating may also be continued during the refining step, the heating gases being supplied separately from the refining gas. Cracking gases or oils may also be supplied during refining, but remote from the zone of impingement of the oxygen stream, whereby the carbon content of the bath may be increased.
