Low - pressure metallic-vapour apparatus ; vacuum tubes.-A rectifier, such as a mercury or other metal vapour rectifier, has solid annular anodes 1, 2, 3 arranged around a common axis. An annular cathode may be used, the diameter of which is greater than that of the outer anode 1. The periphery of the section of the anodes is preferably inversely proportional to the diameter of the anode rings. The mercury cathode vessel 21 may be tapered towards the top to form a neck, and provided at this part with heat-insulating material. The anodes are enclosed in tubular walls 10, 11, 12, the space between the outer wall 10 and a liquid-cooled casing 13 acting as the main condensation space for the cathode vapours. The arc is caused to rotate by means of an electro-magnet 18 secured by a plate 19, and having an annular pole 20 and a conical pole 17 covered by a conical insulating-cap 23, which, in a modification, is formed as a hollow liquid-cooled vessel having annular rings projecting between the walls 10 &c. to prevent cathode vapours passing to the anode spaces. The cathodes may consist of concentric rings or part rings, or may be diskshaped. The anodes may be mounted on hollow leads 7 through which cooling-liquid is supplied, the leads being insulated from the cover 6, or the cover may be made in sections of conducting material insulated from each other. The walls 10 &c. may be secured to the cover by flanges 37. In a modification, the flanges interlock, and are insulated from each other and from the cover. In another arrangement, the walls 11, 12 are supported at the bottom by lugs resting on a circular flange in a resilient manner on the casing 13. In a further arrangement, the walls are supported on laminated springs on the cap 23, which may be divided into sections, the walls being cut away at the bottom to form arch-shaped 'openings. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of an incandescent cathode of annular or disk shape, in one or more parts, instead of a mercury cathode.

Filed: 1929-06-11
Abstract: 314,019. Boehringer, A., (trading as Boehringer Sohn, C. H.). June 21, 1928, [Convention date]. Addition to 312,919. Samples furnished. Hydrogenated pyridine compounds.-Pyridine and piperidine derivatives containing the group CH2.CO.R in the a-position or in the a : a'- positions (R = hydrogen, alkyl, aralkyl or aryl) are subjected to catalytic hydrogenation, whereby one or both of the ketone groups is wholly or partially reduced, and/or the pyridine nucleus or carbocyclic residues (when R represents such) are hydrogenated, according to the reaction conditions. If desired, the reaction may be effected in stages with variation of the conditions in each stage. The starting materials may also be alkylated at the nitrogen atom, e.g. the quaternary salts ma.y be employed. The products are useful therapeutically or for the manufacture of therapeutic substances. According to the examples, (1) a : a<1>-diphenacylpyridine hydrochloride is treated at ordinary temperature in glacial acetic acid solution with hydrogen in the presence of palladium-barium sulphate until 3 mols. of hydrogen are absorbed: further treatment of the resulting alpha-phenylhydroxyethyl-alpha<1>- phenylethylpyridine at a temperature of 40-50‹ C. until another mol. of hydrogen is absorbed gives alpha:alpha<1>-diphenylethylpyridine ; (2) alpha:alpha<1>-diphenacylpyridine hydrochloride dissolved in glacial acetic acid is treated with hydrogen in the presence of platinum oxide until 11 mols. are absorbed, yielding alpha:alpha<1>-di(cyclohexylhydroxyethyl)piperidine ; the same product is also obtained by hydrogenation under these conditions of norlobelanine (a : a'-diphenacylpiperidine) until 8 mols. of hydrogen are taken up. The Specification as open to inspection under Sect. 91 (3) (a) describes also the hydrogenation of starting materials in which the residues R may be different or which contain other substituents, e.g. hydrocarbon residues, amino groups or halogens, in any part of the molecule. It also mentions as catalysts the metals of the platinum group or their oxides, e.g. platinum and nickel, which may be deposited on a carrier.
