Title: Manufacture of new sulphonyl-ureas
Filed: 1956-05-08
Abstract: The invention comprises sulphonyl ureas of the general formula R-SO2-NH-CO-NHR1 in which R is an aliphatic or cycloaliphatic hydrocarbon radical containing from 3 to 8 carbon atoms and R1 is an aliphatic or cycloaliphatic hydrocarbon radical containing from 2 to 8 carbon atoms, preferably 3 to 5 carbon atoms, and physiologically acceptable salts of these compounds.  The products are made by known methods for the production of sulphonyl ureas, for example: (1) an aliphatic or cycloaliphatic sulphonyl isocyanate is reacted with an aliphatic or cycloaliphatic amine; in place of the isocyanate a compound convertible into an isocyanate during the reaction such as an azide, or a urethane or carbamic acid halide may be used; (2) an alkyl sulphonyl-urea is converted into an alkyl-sulphonyl-alkyl-urea, for example with butylamine or an alkyl urea may be reacted with a sulphonamide; in place of the alkyl urea a corresponding iso-urea ether may be used which is reacted with an alkyl-sulphonic acid chloride; (3) a corresponding thiourea compound is first formed and sulphur is eliminated by known methods, e.g. by treatment with a heavy metal oxide or salt; and (4) an N-alkyl sulphonyl-N1-alkyl guanidine, prepared for example by reacting an alkylsulphonylcyanamide with a primary amine, is hydrolysed.  In the above methods the alkyl sulphonyl compounds may be replaced by a cycloalkyl sulphonyl compound and the alkyl amine by a cycloalkylamine or cycloalkyl-alkyl-amine. The products are used in the treatment of diabetes.  Examples describe the preparation of sulphonyl-ureas of the above general formula in which the substituents R and R1 are respectively cyclohexyl-, butyl-; cyclohexyl-, cyclohexyl-; butyl-, butyl-; cyclohexyl-, isobutyl-; cyclohexyl-, allyl-; 3-methylbutyl-, butyl-; cyclohexylmethyl-, butyl-; pentyl-(3)-, hexyl-(1)- and cyclohexyl-, cyclohexylmethyl-groups.  Cyclohexanesulphonyl isocyanate is prepared from cyclohexane-sulphonamide and phosgene.ALSO:Anti-diabetic preparations for oral administration comprise compounds of the formula R.SO2.NH.CO.NH.R1, in which R is an aliphatic or cycloaliphatic hydrocarbon group of 3-8 carbon atoms such as propyl, butyl, pentyl, hexyl, cyclohexyl or hexahydrobenzyl and R1 is an aliphatic or cycloaliphatic hydrocarbon radical of 2-8 carbon atoms such as ethyl, propyl, allyl, butyl, butenyl, pentyl, hexyl, cyclohexyl or hexahydrobenzyl or salts of these compounds with bases which give physiologically tolerated salts, in admixture with a pharmaceutically suitable carrier.  The preparations suitably take the form of tablets, pills, capsules, cachets, mixtures, solutions or powders, containing, for example, 0.5 grams of sulphonyl urea compound per dosage unit.  Many suitable active compounds are specified (see Group IV (b)).  In an example N-cyclohexyl - sulphonyl - N1 - n - butyl - urea is made into tablets with wheat or maize starch, talc and magnesium stearate; in place of the above sulphonyl urea, the corresponding N-cyclohexylsulphonyl - N1 - cyclohexylmethyl and N - (n-butylsulphonyl)-N1-n-butyl ureas may be used.

Abstract: 617,774. Latches. ENDTER, W. A. Sept.. 4, 1944. No. 16866. Convention date, Aug. 6, 1943. [Class 44] Latch mechanism, particularly for vehicle doors, comprises a rotatable latch element which engages a boss or keeper on the door post, cam means rotating the latch in locking direction, and releasable stop means engaging with the rotating latch to hold the latter against reverse rotation in different positions within the range of its rotation by the cam. The latch element 11, Figs. 1 and 2, is mounted to rotate on a shaft 12, the outer portion projecting through the flange 10a of the casing. The casing carries an abutment 18, between which and the latch 11 engages a keeper 19, Fig. 6, mounted on the door post. The. latch 11 is urged to rotate in a counterclockwise direction as seen in Fig 6, by means of spring pressed wedge and stop plates 20, 25, the former having an inclined surface bearing on the engaging tooth of the latch, and the latter having a series of steps 27. 28, 29 which hold the latch positively against reverse rotation as the keeper 19 moves into more closely engaging position. The initial rotation of the latch by the keeper engaging one tooth thereof causes the adjacent tooth to lift the plates 20, 25 until it passes the lower corner of the latter, when the wedge action of the plates under the influence of the springs tends to cause the latch to turn so as to engage more firmly. To release the latch, the plates 20, 25 are lifted by a follower 34, Fig. 2, or by an arm 42, both of which engage a lug 41 extending from the plate 25 and passing below the lower end of plate 20. The follower 34 is operated by an external handle and the arm 42 by an inside handle. A slotted link 45 engaging a pin 44 on arm 42 may be shifted longitudinally to prevent operation of the follower 35 by overlying its upper surface 48. In a modified construction the wedge and stepped plates are pivotally mounted. The three-toothed latch element 52, Fig. 10, rotates on a pin 55 and is engaged by a keeper 59 on the door post. A boss 61 also on the post engages the top of the housing 58 of the latch. A number of cam elements 62, 63 are mounted on a pin 64, together with a stepped cam plate 68, each pressed downwardly towards the latch by a spring. The operative cam surfaces tend to rotate the latch in counter-clockwise direction as seen in Figs. 10, 14, and the stepped plate prevents reverse rotation. The action is similar to that of the first described construction. Release of the latch is effected by means of follower mechanism acting on a lug 70, projecting from the stepped plate 68 and engaging under projections on the cam plates 62, 63. Specification 484,538 is referred to.
