Patent GB-210095-A (GB)
Title: Manufacture of bismuth-compounds
IPC: C07F9/94
Filed: 1924-01-22
Abstract: Bismuth compounds of aminophenols, having a side chain containing hydroxyl attached to the nitrogen of the amino group, are prepared either by treating with a bismuth salt an aminophenol having such a side chain or a derivative thereof substituted in the nucleus by an acid radical such as a carboxyl group, or by introducing a side chain containing hydroxyl into the amino group of a bismuth compound of an aminophenol or of a derivative thereof substituted in the nucleus by an acid radical such as a carboxyl group.  The products act upon spirochaetae and other bacteria causing infectious diseases.  In examples a solution of bismuth nitrate in glacial acetic acid is added to an aqueous solution of the sodium salt of 3-N-dioxypropylamino-4-oxybenzoic acid and the precipitate filtered, washed with alcohol and dried, the sodium salt being formed by solution in sodium carbonate; glacial acetic acid solutions of 3-amino-4-oxybenzoic acid are mixed, sodium acetate added, and the bismuth compound heated in the form of its sodium salt in aqueous solution with grape sugar.  The Specification as open to inspection under Sect. 91 (3) (a) describes the production by the above two methods of bismuth compounds of aromatic substances in general having a side chain containing hydroxyl.  This subject-matter does not appear in the Specification as accepted.  Sodium 3-N-dioxypropylamino-4-oxybenzoate is prepared by treating 3-amino-4-oxybenzoic acid with sodium ethylate to form the sodium salt and condensing with glycide.

Patent GB-427912-A (GB)
Title: An improved method of joining metal pipes, and pipe structures made thereby
IPC: B21D39/04
Filed: 1934-01-18
Abstract: 427,912. Joining pipes by welding. SUPERHEATER CO., Ltd., and BOYES, F. A., Bush House, Aldwych, London. Jan. 18, 1934, No. 1819. [Class 83 (iv)] Axially aligned metal pipes are joined by swaging down the end of one pipe and enlarging the end of the other without reducing the wall thickness of either, heating the ends, inserting one within the other, placing them between female dies and forcing a male die into the bore of reduced diameter so as to weld the overlapping portions of the pipe ends. The pipe 2, Fig. 2, is reduced at 3 and the pipe 1 opened out at 4 and the ends may be heated before or after being assembled. The heated assembly is inserted in a split female die 6, Fig. 5, having a barrel shaped recess 7 to receive the displaced metal, and a male die 8 is forced through the overlapping pipe ends to effect the weld and restore the original bore to the pipes. The inward stroke of the die 8 follows closely on the closing of the die 6 to minimize loss of heat from the pipe ends. The heating may be effected by a gas, electric &c. furnace which may be portable or otherwise, and the pipe ends may be held together during heating by tack welding by the electric arc or oxy-acetylene process. Alternatively, the pipe ends may be heated by passing an electric current through them whilst in contact, and the ends may be subsequently separated to produce an arc, the current being cut off when the required degree of heat has been attained. When the heating is by electricity, the die 6 may be assembled about the joint during heating. If it is desired to remove the protuberance 11 on the joint, the pipes may be re-heated in the region of the weld, a mandrel 8, Fig. 6, inserted, and then placed between swage blocks 12 having cylindrical recesses 13 and subjected to the action of a rotary swaging machine, mechanical hammer, &c. Alternatively, the welding and finishing may be performed in one operation by means of a female die 14, Fig. 8, having a cylindrical recess enlarged at one end 15 to receive the overlapping pipe ends. The first portion of the stroke of the male die 8 welds the joint and subsequently a shoulder 16 on the die engages the end of the pipe 2 to force the assembly through the cylindrical part of the die 14. If the two pipes are of different material or thickness, one may be preheated in order that both may reach welding temperature simultaneously when heated together. Short lengths of mild steel or carbon steel tubing may be united to alloy steel tubes by the process described to form steam superheater elements, or the legs of "breeches pieces" may be attached to a number of alloy steel tubes.

Title: Process for preventing the sedimentation and gelatinisation of solutions of driers in volatile organic solvents
IPC: C09F9/00
Filed: 1931-01-21
Abstract: To prevent sedimentation and gelatinization of solutions of naphthenate, linoleate, and resinate driers in volatile organic solvents, olefinic or aromatic carboxylic acids are added to the solutions.  Acids specified are the free fatty acids of drying and semi-drying oils (including linoleic acid and perillic acid), crotonic acid, phthalic acid, benzoic acid and its homologues and derivatives having a free carboxyl group in the nucleus or side-chain, such as o, m, and p amino-, chloro-, and nitro-benzoic acids and hippuric acid.  Free benzoic acid also accelerates the dissolving of the drier, and reliquefies thickened drier solutions and gelatinized lacquers.  The quantity of fatty acid required may be, for example, from 3 to 20 per cent of the solid drier, and smaller amounts of benzoic acid, down to one-fourth, may be used. In examples the materials used are (1) cobalt naphthenate dissolved in lacquer benzine with or without carbon tetrachloride or other chlorinated hydrocarbon, and the fatty acids of soya bean oil; (2) cobalt-lead resinate, volatile solvents, and linoleic acid; (3) zinc and cobalt naphthenates, mixed terpenes, benzole and perillic acid; (4) cobalt napthenate, lacquer benzine or other solvent; and benzoic acid, (5) manganese linoleate, sangajol (a petroleum fraction boiling from 150 DEG -190 DEG  C.), and o-aminobenzoic acid; (6) cobalt-zinc resinate, turpentine, and phthalic acid; (7) cobalt-manganese naphthenate, benzaldehyde (which becomes converted into benzoic acid), and hippuric acid, mixed terpenes and benzole.  Specifications 339,865 and 339,922, [both in Class 95, Paints &c.], are referred to.

Title: Electron discharge apparatus
IPC: H01J25/68
Filed: 1938-01-21
Abstract: 495,529. Discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Jan. 21, 1938, No. 2070. Convention date, Feb. 26, 1937. [Class 39 (i)] An electron-discharge device comprises a cathode 17 and an output electrode encompassing the cathode and having a cylindrical portion 25 which is coaxial therewith and is formed with a slot and constitutes an inductance, a pair of plate members 28 being mounted on the parts of the cylindrical portion 25 adjacent the slot to form a condenser. Grids 19, 22 surround the cathode, the wires of the grids being arranged in alignment. The inner surface of the part 25 is rendered secondary emitting and two horseshoe magnets 29, 30 are arranged with their poles immediately above and below the tube and with their fields equal and oppositely directed. The fields and potentials are so chosen that for steady state conditions the primary current to the plate and the secondary current therefrom to the outer grid are substantially equal and the resultant plate current decreases as the plate potential increases. When a current circulates in the circuit formed by the parts 25, 28, the magnetic field produced thereby opposes the field of one magnet and aids the field of the other; in the region of the former magnet, the resultant current to the portion of the plate is increased and in the region of the latter it is decreased, thus providing a negative resistance in the circuit 25, 28. Oscillations in the circuit are picked up in a conductor 31 encircling the vessel 10, or a capacitative pick-up may be used. Mica may be interposed between the plates 28.
