Novel disulphonamides (and salts thereof) of the general formula (and also the corresponding compounds wherein the heterocyclic ring is broken between the members N and X and accordingly the resulting nitrogen bond is satisfied by a hydrogen atom and X is a carboxy (-COOH) group) wherein R is H or Me, R<SP>1</SP> is H or C 1-4  alkyl, R<SP>11</SP> is H, C 1-4  alkyl, alkoxyalkyl, aryl or aralkyl, X is carbonyl or methylene and n is 0 or 1 are prepared by the interaction of 4-chloro-3-sulphonamido-benzenesulphochloride and the appropriate aminomethyl- or methylamino -compound. Pharmaceutical compositions having diuretic and saluretic activity, and suitable for the treatment of hypertension, contain as the active ingredient the above novel compounds and are preferably administered parenterally in the form of capsules, tablets, pills, powder, granulates or suppositories and ampoules or drops. N - # - Methoxyethyl -, N - benzyl - and N - #- phenethyl - 5 - methyl - 5 - cyano - pyrrolidone- (2) are prepared by the interaction of laevulinic acid ethyl ester cyanohydrin and #-methoxyethylamine, benzylamine or #-phenethylamine respectively. Reduction of the cyano groups therein yields the respective N-substituted-5- methyl - 5 - aminomethyl - pyrrolidone - (2); N- methyl - and N - ethyl - 5 - methyl - 5 - aminomethyl-pyrrolidone-(2) are also described. Treatment of the 5-methyl-5-aminomethyl-pyrrolidones, wherein the N-substituent is a methyl, ethyl, benzyl or #-methoxyethyl group or attached to nitrogen is a hydrogen atom, with benzaldehyde and dimethyl sulphate yields the corresponding 5-methyl-5-methylaminomethylpyrrolidone. Reduction of 6-cyano-6,N-dimethyl-piperidone- (2), which is prepared by the interaction of 4- acetyl butyric acid ethyl ester cyanohydrin (from the ester and hydrocyanic acid) and methylamine, yields 6,N - dimethyl - 6 - aminomethylpiperidone-(2). N, 2 - Dimethyl - 2 - methylaminomethylpyrrolidine is obtained by reducing 5-formylaminomethyl - N,5 - dimethyl - pyrrolidone - (2) which in turn is prepared by the reaction of ethyl formate with 5-methylaminomethyl-N,5- dimetbyl-pyrrolidone-(2). N - Methyl - 2 - methylaminomethyl - pyrrolidine is obtained by the reaction of N-methyl- 3-chloropiperidine with methylamine.

[Class 82 (ii).] The apparatus for granulating slag claimed in the parent Specification is modified by the provision of a plurality of sets of disintegrating nozzles, the flow of water through each set of nozzles being independently controllable, and by the provision of one or more breaking plates against which the slag is thrown by the disintegrating jets before falling into the fluid conveyer. Molten slag falls from a spout 1 into a disintegrating chamber on the exterior of which is a manifold 7 containing sets of nozzles 8, 9 fed by pipes 10, 11 with water at high pressure, the flow through each of the sets of nozzles being independently controlled by cocks 12, 13. The slag is thrown by the jets against breaking plates 4, 5 and falls into a fluid conveyer formed in a sluiceway by water jets from a nozzle box 14 which carries it against a breaking plate 6 from which it falls into a main sluiceway 3. The sets of nozzles or some of them are arranged so that their height may be adjusted if the height of the slag spout in the furnace is varied, for example by raising or lowering the plate on which the manifold 7 is mounted. When the slag is first tapped water is supplied through both sets of nozzles 8, 9 but when the rate of flow of slag decreases the flow of water through one set of nozzles may be reduced or stopped.

Title: Improvements in or relating to radioscopic apparatus for examining subjects in vertical or horizontal positions
IPC: A61B6/00
Filed: 1950-09-01
Abstract: 698,050. X-ray apparatus. POITTEVIN, M. Sept. 1, 1950 [Sept. 1, 1949; Sept. 1, 1949], No. 21645/50. Class 98 (i). In radioscopic apparatus for examining patients in vertical and horizontal positions, the unit comprising the X-ray tube 2 and the fluorescent screen 1 is movable about a horizontal shaft 4 perpendicular to the line from the ray source to the centre of screen 1 and carried by a column 9, the distance from shaft 4 to the perpendicular to the centre of the screen is greater than the distance from the shaft 4 to the plane of the screen, and means are provided for locking the rotatable unit to the column comprising a bolt 14 sliding within column 9, a spring 15 pushing the bolt 14 into a movable part 12 supporting the tube 2 and screen 1, a piston 16 sliding within the part 12, a spring 17 stronger than spring 15 pushing piston 16 against bolt 14, and a key 18 which in one position allows separation of the piston from the bolt and in the other position places the piston in contact with the bolt, the springs being so dimensioned that unlocking of part 12 only occurs if the friction between the hinged members and bolt 14 becomes less than the difference of the forces exerted by the springs. Key 18 has a nose 18<SP>1</SP> which enters a groove in piston 16 and, in the position shown, keeps it moved to the right. The piston can be freed by turning key 18 through 180 degrees, but if the part 12 is unsupported, the weight of the tube 2 and screen 1 sets up frictional forces on piston 16, preventing it from moving. When part 12 is supported the frictional forces vanish, and spring 17 moves piston 16 and bolt 14 against action of the weaker spring 15.

Title: Improvements in or relating to catalytic conversions using carbon monoxide
IPC: C07C27/22
Filed: 1948-08-17
Abstract: Reactants containing carbon monoxide are contacted with a catalyst containing an iron group metal in a reaction zone at below 400 DEG F. and above 150 p.s.i. to obtain the desired conversion, the products which contain metal carbonyl are passed to a secondary zone at a pressure below 100 p.s.i. and a temperature approximately 50-100 DEG  F. above that of the reaction zone to decompose the carbonyl, and the flow of reactants and products is periodically reversed with respect to said reaction zone and secondary zone.  The secondary zone may contain a surface-active material or spent catalyst on which the metal is deposited.  Ethylene, carbon monoxide and hydrogen may be converted to diethyl ketone and propionaldehyde by compressing to above 200, e.g. 700 p.s.i., preheating to 100-300 DEG , e.g. 150 DEG F., in preheater 4, and passing through primary reactor 12 containing cobalt, diatomaceous earth, magnesia and thoria.  The effluent may contain 1.5-4 per cent cobalt carbonyl, and is heated to about 50-100 DEG  F. above the reaction temperature in heater 15 before passing by conduit 16 to secondary zone 22 which is at a pressure below 100 p.s.i., preferably about atmospheric, and may contain surface-active material.  Inlet pipes 17-19 aid in distributing the metallic cobalt formed by <PICT:0672880/IV (b)/1> decomposition, and active catalyst forms in zone 22.  Hydrogen may be introduced by pipes 52, 53, and 16.  The effluent passes by pipe 24 to cooler 28, condensed products being separated in 32 into water, and organic products which are fractionated in 40 to recover desired components.  Gases are recycled by line 34.  Flow of reactants is reversed by introducing them to zone 22 by line 9, the effluent passing by line 45 and heater 46 to zone 12 through pipes 48-50.  Conversion products pass by lines 13, 26 to cooler 28.  Catalyst may be regenerated by heating in hydrogen. Catalysts may be fluidized by mechanical means as in U.S.A. Specification 2,501,695.  Specification 637,389 also is referred to.
