Title: Improvements in process of reacting glyceride oils
IPC: C11C3/06
Filed: 1949-02-01
Abstract: Partial esters of polyhydric alcohols, formed by methanolysis of a fatty oil, and reaction of the mixture of glycerol and methyl esters of fatty acid so obtained with added polyhydric alcohol (see Group IV (b)), are reacted with a polycarboxylic acid or anhydride, preferably at 200-300 DEG  C., and in presence of an inert gas, to give a resin. In examples: (1) the partial ester as above prepared from dehydrated castor oil and added glycerol is heated with phthalic anhydride; (2) the partial ester from soyabean oil and pentaerythritol is heated with sebacic acid or maleic anhydride; (3) the partial ester from linseed oil and propylene glycol is heated with maleic acid.  Other polycarboxylic compounds specified are fumaric acid, azelaic acid, malic acid, ketomalic acid, citric acid, phthalic acid, hemimellitic acid. Alcohols specified are glycocol, pentaerythritol mannitol, propylene glycol.ALSO:Partial esters of polyhydric alcohols and higher fatty acids are made by reacting a substantially neutral fatty oil with at least 6 mols. of methyl alcohol in presence of an esterification catalyst until the ester interchange reaction is substantially completed, and heating the thus-formed mixture of glycerine and fatty acid methyl esters with added polyhydric alcohol while distilling off the methyl alcohol.  Fatty oils specified are soyabean, dehydrated castor, tung, oiticaca, linseed, or rapeseed. Catalysts specified include alkali and alkaline earth hydroxides and alcoholates, and certain quaternary ammonium hydroxides. Polyhydric alcohols specified are glycerol, pentaerythritol, mannitol, and propylene glycol.  The esters are neutralized before use as, e.g. hydraulic fluids or plasticizers.  They may be converted to resins by reaction with a polycarboxylic acid or anhydride (see Group IV (a)). In examples: (1) dehydrated castor oil is reacted with methyl alcohol in presence of caustic soda, and then with added glycerol; (2) soyabean oil is reacted with methyl alcohol in presence of phenyltrimethylammonium hydroxide, and the mixture of glycerol and methyl esters so obtained is reacted with pentaerythritol; (3) linseed oil is reacted with methyl alcohol in presence of sodium methylate, and the resulting mixture with sodium methylate; (4) tung oil is reacted with methyl alcohol in presence of lime, and the resulting mixture is reacted with glycerol.

Title: Improvements in or relating to welding rods
IPC: B23K35/40
Filed: 1943-02-19
Abstract: 574,550. Obtaining coherent masses from powdered metals. CLARKE,, E. J and MUREX WELDING PROCESSES, Ltd. Feb. 19, 1943, No. 2780. [Class 82 (i)] [Also in Group XXII] A weld rod for use in electric or gas welding, particularly of pressure vessels, is made by forming a billet by sintering a metal powder and then shaping the billet into a weld rod by rolling or swaging and drawing. The powder may be a powder of a single metal or of a mixture of metals or may contain an alloy powder. Fluxing agents such as rutile, fluorspar, felspar or magnesite, deoxidisers such as ferro - silicon or ferro - manganese, and arc stabilisers such as ferrous silicate or titanium dioxide &c. may be mixed with the metal powders prior to sintering or may be applied as a coating to a finished weld rod. Some or all of the alloying or deoxidising ingredients may be contained in the coating. A welding rod for welding chrome nickel steel may cornprise a mixture, of iron powder together with a mixture of nickel and chromium powders or a nickel chromium alloy powder and for welding copper and copper alloy may comprise a mixture of copper powder together with tin, manganese or aluminium or nickel. In one method, an iron powder of 99.8 per cent purity is subjected to a piessure of 10 to 30 tons per sq. in. in a steel mould and then sintered in hydrogen between. 800‹ and 1400‹ C. for one to eight hours. The billets are then forged at 700‹ to 900‹ C. and hot rolled and cold drawn to form. the core which is then flux coated. The iron powder may, alternatively, be mixed with 5 per cent of ferrous silicate and titanium dioxide and 10 per cent of ferro-manganese in a ball mill for two hours prior to forming into the billet. The weld rod may in this case also be coated with flux. The mixture of the previous example may be neated in an alloy steel mould by a high-frequency coil or by the passage of a. current in a hydrogen atmosphere, and pressed at from 5 to 30 tons while the temperature is raised to 500-800‹ C. for 10 minutes until sintering is'complete, whereupon ' the billet is reheated to 700-900‹ C. and reduced as previously described. In another modification of the second process, the powder may consist of 18 to 20 per cent of chromium, 8 to 10 per cent of nickel, 3 to 5 per cent-of molybdenum, not more than 5 per cent of titanium dioxide and the balance iron. In a further example, the ingredients may consist of 20 per cent of 50/50 copper:aluminium alloy, 1-3 per cent of ferro-manganese, 3-5 per cent of nickel and the balance copper.

Title: Improvements in or relating to the manufacture of compact oxide bodies
IPC: H01B1/08
Filed: 1962-01-30
Abstract: Compact coherent oxide bodies of manganese and/or iron are produced by dripping a solution (preferably saturated) of the nitrates of iron and/or manganese into a mould heated such that pyrolysis of the nitrate salts occurs, thus leaving a deposit of oxide.  The mould may then be removed and the oxide body obtained may be aftertreated especially by heating with concentrated nitric acid in a sealed tube or by heating in a concentrated aqueous solution of hydrofluoric acid to effect oxidation.  In particular, compact bodies of Mn2O3 are obtained by dripping a solution of manganese nitrate into a mould at 500 DEG  C. or less and subjecting the oxide body obtained to a heating treatment in air or other oxidizing atmosphere at a temperature of from 530-940 DEG  C.  a -Fe2O3 may be produced by the process.

Title: Improvements in a mechanical relay device
IPC: H02K7/065
Filed: 1942-03-16
Abstract: 561,832. Relay devices. RANSFORD, A. J. (Svenska Aeroplan Aktiebolaget). March 16, 1942, No. 3465. A Specification was laid open to inspection under Sect. 91 of the Acts, Aug. 7, 1942. [Class 118 (ii)] A mechanical relay, e.g. for instruments with small directional force such as barometers, and altitude and speed measuring devices for aircraft, comprises a source of power, e.g. an electric motor 1, Fig. 1, adapted, through a crank 2 and connecting-rod 3 to reciprocate a rod 4. A member 7 is slidably mounted on the rod and is urged towards a flange 10 thereon by a spring 11. The member 7 is mounted in guides 5, 6 and carries a pivoted arm 8 which serves as a pawl for actuating a ratchet wheel 9 connected to the part to be driven and backward motion of which is prevented by a detent 17. A bolt 13 lies normally in the path of the member 7 and is adapted to be withdrawn by an electromagnet 12 against a spring 14, the current for the magnet being controlled by a contact 15 actuated by the weak source of power. In operation, until the bolt has been withdrawn, no movement is imparted to member 7, the spring 11 being alternately compressed and extended. When contact 15 is closed, the bolt 13 is withdrawn and the member 7 is urged by spring 11 to contact with the flange 10 and moves with member 4, thus actuating the ratchet wheel 9. By providing a second contact device 22 actuated by a flange 23, current may only be allowed to flow for short periods to prevent burning out of parts of the apparatus. In a modification, Fig. 2, the power source comprises a swivelling crank-pin 41 through which slides a rod 24 pivoted at 27 to a disc driving member 7<1> having on its periphery a shoulder 26 adapted to be engaged by a stop 13<1> corresponding to the bolt 13, Fig. 1. A spring 11<1> is inserted between a fixed abutment 25 and a collar 23<1> on the rod 24. With the stop 13<1> removed, the disc 71 is oscillated. Arrangements are made to relieve pressure on the bolt 13 and stop 13<1> at each end of a stroke or swing. The contact 22, Fig. 1, may be replaced by a rotary contact driven by the motor 1. The change-over may be effected also by pneumatic, hydraulic, mechanical or manual operation. The Specification as open to inspection under Sect. 91 describes also a construction in which the spring 11 is dispensed with. The member 7, Fig. 2 (cancelled), has a transverse bore 21 in which is inserted a pin 18 adapted to embrace the driven member 4 and also to engage a notch 20 therein when the locking bolt 13 has been withdrawn. A flange 10 is provided, as before, on the member 4. This subject-matter does not appear in the Specification as accepted.
