Title: Process for the manufacture of amides of higher fatty acids
IPC: C11C3/00
Filed: 1931-06-04
Abstract: Amides of higher fatty acids are produced by heating natural or synthetic glycerides with ammonia or monamines (except purely aromatic monamines) with exclusion of water, the quantity of ammonia or amine being such that not more than 5-10 per cent excess remains in the reaction mass at the end of the reaction. When the nitrogenous reagent is volatile, an autoclave may be used; otherwise a reflux condenser is suitable or the amine may be pumped back in a closed system.  Catalysts such as copper, nickel, or their oxides or salts may be employed.  Glycerides mentioned are olive, castor, linseed, wood, rape seed, arachis, poppy seed, palm kernel, palm, soya bean, coco nut, and train oils, tallow, and Japan wax, and the amines are methylamine, butylamine, undecylamine, benzylamine, diethylamine, dibutylamine, piperidine, diethanolamine, cyclohexylethylamine, dicyclohexylamine, and dibenzylamine.  Solvents may be employed in limited quantity so as not to cause more than the stated excess of ammonia or amine to remain in the reaction product.  In examples (1) olive oil is reacted with ammonia at 100-150 DEG  C. in a stirring autoclave; (2) beef tallow with a small quantity of methanol is reacted with ammonia at 80-150 DEG  C. in a stirring autoclave; (3) beef tallow is heated in an autoclave connected with an ammonia bomb (8-12 atmospheres); (4) castor oil is heated in an autoclave connected with an ammonia bomb (2-3 atmospheres; (5) castor oil is reacted with cyclohexylamine at 130-150 DEG  C.; (6) olive oil and coco-nut oil are heated under reflux with ethanolamine; (7) coco-nut oil is reacted with ammonia at 180-200 DEG  C.  The products are suitable for use instead of fats in the textile, leather, paper, soap and perfumery industries, and in the preparation of pharmaceutical preparations and cosmetics. Specification 343,899 is referred to.ALSO:Amides of higher fatty acids, made from glycerides such as fatty oils, tallow and Japan wax by reaction with ammonia or amines (other than purely aromatic amines) such as methylamine, butylamine, dibutylamine, undecylamine, benzylamine, piperidine, diethanolamine, cyclohexylethylamine, dicyclohexylamine and dibenzylamine, are suitable for use instead of fats in the soap and perfumery industries, and in the production of cosmetics and pharmaceutical preparations.

Patent GB-897495-A (GB)
Title: Agglomeration process for pulverized ores
IPC: C22B1/245
Filed: 1960-05-11
Abstract: Pellated ores produced by agglomerating the finely divided ore with a bituminous emulsion, and baking the resultant pellets, are given a superficial coating of asphaltic bitumen by treatment (spraying or dipping) with a cutback, so that after evaporation of the solvent the bitumen preferably constitutes 0,1 to 5% by weight of the pellets. Suitable solvents are naphthas and hydrocarbon oils.ALSO:Finely divided ores are agglomerated by agitation with a bituminous emulsion to yield pellets containing 5-20% of water, the 'green' pellets being subsequently baked, either in absence or presence of air, in the range 200-350 DEG C. for 1/2 to 24 hours.  The proportion and composition of emulsion used is such that after baking the pellets contain 1,5-10% of bitumen.  Other possible constituents of the emulsion include inorganic hydroxides or clay as dispersing agents, and soaps (e.g. sodium tallate), petroleum-insoluble pine wood resins and their alkali metal salts, sodium petroleum sulphonates and sodium ligno-sulphonates as stabilizing agents.  The aqueous phase may contain thickening agents, such as hydroxy-ethyl cellulose, methyl cellulose, carboxy methyl cellulose, sodium carboxy methyl cellulose, clays, gums or inorganic salts such as sodium chloride.  The baked pellets may be given an increased resistance to abrasion and moisture by spraying with or dipping in a cutback so that the surface coating of asphaltic bitumen remaining after evaporation of the solvent constitutes 0,1-5% by weight of the pellet.  In a modification of the agglomerating process the baking stage may be combined with a direct reduction process in a single furnace.

The work may be coated with a flux, or a reducing atmosphere otherwise provided, during the preheating operation. To avoid loss of charge from the condenser during pre-heating, the switch 12 may be omitted and a normally closed switch, preferably of the ignitron type, provided on the input side of the rectifier, this switch being arranged to open only when the short-circuiting switch of the resistance is closed.

Abstract: 273,710. Snyders, G. C., Gordyn, C., Kamp, J. van de, and Maitland, C. E. A. July 3, 1926, [Convention date]. Fire, police, and like alarm systems.-In systems in which calls received at a central station are repeated to a district substation, a preliminary alarm is given at the substation prior to the repetition of the call. In the system described a calling station AGST 431 is connected by a line-finder AS at a distributing station VSt 1 to a trunk leading to the central station HBW, from which calls are repeated by means not described to substations FW1, FW2, a preliminary warning being given by the hooter AH when the circuit of relay R is closed at the central station. Successive sets of impulses, corresponding to the number of the calling line, are repeated by the relay A over the trunks a, b in parallel to the impulse relay J at the central station. A slowrelease relay K1, under control of relay J, causes relays V1, V2, V3 to bring the magnets D1, H, D2 successively under the control of relay J. Magnet D1 sets the switch W1 to select the hundreds lamp H4, say, and magnets H, D2 operate a co-ordinate selector W2 to select tens and units lamps Z3, E1, say. The insertion of the plug AbA to set up telephonic communication with the calling line causes relay L to close the circuits of the selected lamps. The circuit of the relay R controlling the hooter AH at the substation FW1 is closed by the relay VI at the end of the hundreds impulses, and opened by the relay V3 at the end of the units impulses. The depression of the release key AT causes relay F to restore the selector W1 and to open the circuit of the test relay P thereby energizing the release magnet M of the selector W2. Lamps L1, L3, L4 at the control station indicate the progress of the call and lamp L2 indicates the district from which the call is transmitted. Keys WT1, WT2 are provided in the central station to facilitate selection of a district substation, Specification, 269,941 is referred to.

As shown in Fig. 3, the unit comprises a rectangular casing with a flange F round its base on which a series of terminals are mounted. The unit encloses the coupling-elements for a detector valve followed by two low-frequency amplifiers. The plates of the three valves are connected to the terminals p<1> - - p<3>, and the grids of the second and third valves to terminals g', g<2>. The inter-valve coupling-elements comprise plate resistances 7, 8 coupling condensers 9, 10 and grid chokes 12, 13 ; whilst the output circuit of the last valve includes a choke 14 and a condenser 11 leading to the loud-speaker terminal l. Hightension is applied at the terminal h and grid bias at terminals b<1>, b<2>. A high-frequency choke is included in the detector plate circuit. The coupling-condensers may be connected to tappings on the chokes 12, 13 or to their grid ends. Similar units for two valve stages may be arranged in cylindrical cases, and may include a transformer output instead of the choke-capacity arrangement shown. Chokes may be substituted for the plate resistances 7, 8 and grid-leak resistances for the chokes 12, 13. The various terminals are labelled to indicate their correct connection, and a celluloid sheet showing the circuit diagram may be mounted on the top of the casing. The units are particularly intended for adding stages of amplification to an existing set.
