Patent GB-1012620-A (GB)
Title: Isothiazole derivatives
Inventor: CATON MICHAEL PETER LEAR
IPC: C07D275/02
Filed: 1962-08-14
Abstract: The invention comprises compounds of the formula <FORM:1012620/C2/1> wherein R1 represents a hydrogen or halogen atom or a lower alkyl group, R2 represents a hydrogen atom or a lower alkyl group and R3 and R4 are the same or different and each represents a hydrogen atom or a lower alkyl radical, where the term "lower" means that the groups so qualified contain at most 6 carbon atoms, and the preparation thereof by a process wherein an aldehyde or ketone of the formula <FORM:1012620/C2/2> an acetal, diacetate, oxime or semicarbazone thereof is reacted with a thiosemicarbazide of the formula <FORM:1012620/C2/3> or an acid addition salt thereof, and a process for the preparation of compounds of the general formula (I) wherein R7 and R4 represent hydrogen atoms wherein a hydrazone of the formula <FORM:1012620/C2/4> is reacted with an alkali metal thiocyanate in the presence of a mineral acid.  Compounds of the general formula (I) when R2 represents a hydrogen atom may be prepared by the reaction of an arylsulphonylcarboxyhydrazide of the formula <FORM:1012620/C2/5> wherein Ar represents an aryl group, with a thiosemicarbazide of the Formula (III) or an acid addition salt thereof.  Carbonyl compounds of the Formula (II) may be prepared by reaction of an isothazol-5-yl lithium with an amide of the formula <FORM:1012620/C2/6> wherein R5 and R6 represent lower alkyl groups; by reduction of an isothiazo-5-yl nitrile with lithium trimethoxyaluminium hydride, and by reaction of an isothiazol-5-yl nitrile with a Grignard reagent of the formula R2MgHal where Hal represents a hydrogen atom and R2 represents a lower alkyl group. The arylsulphenylcarboxyhydrazides of the formula (IV) may be prepared by reaction of an isothiazol-5-yl carboxyhydrazide with an arylsulphonylhydrazide.  Isothiazol-5-yl lithium derivatives may be prepared by reaction of a 5-unsubstituted isothiazole with an organo-lithium compound, e.g. an alkyl or aryl lithium. Pharmaceutical compositions for oral or parenteral administration, which may take the form of tablets, pills, dispersible powders, granules, emulsions, solutions, suspensions, syrups, elixirs and capsules, having antiviral properties with high activity against the pox group of viruses, comprise compounds of the general formula (I) and a pharmaceutical carrier. For veterinary use, the compounds may be incorporated in animal foodstuffs.

Patent GB-647522-A (GB)
Title: Improvements in and relating to snap acting control devices applicable to electric switches, fluid control valves, and the like
IPC: F16H35/14
Filed: 1945-11-21
Abstract: 647,522. Thermal switches; snap-action switches; switches actuated by fluid pressure. HENRY, P. Nov. 21, 1945, No. 31372. Convention date, Jan. 15. [Class 38 (v)] [Also in Groups XIII, XXIX and XXXII] A snap-acting device actuated by a change in temperature, pressure or humidity or manually for controlling an electric switch comprises, when actuated by a change in temperature, three bimetallic elements 2, Fig. 7, equally spaced around and secured to a circular plate 6, and resiliently supporting and exerting a radial thrust on a shaft 1. Secured to the upper end of the shaft 1 is a control member 11 of insulating material carrying at its ends contacts 12, Fig. 3, connected by a conductor 13 and arranged to coact with contact members 14 mounted on a mica &c. plate 16 or with stop members 17 also mounted on the plate 16. The plates 6, 16 are arranged for angular adjustment relative to each other to vary the range of operating temperatures and are clamped around their peripheries between the casing parts 31, 32, Fig. 4. Openings in the base of the casing part 32 permit access of the gas whose temperature is being controlled. An increase in temperature of the gas causes the bimetallic elements to exert a tangential force on the shaft and rotate it with a snap-action in a clockwise direction, until arrested by the stops 17, to break contact between the contacts 12 and the members 14. Conversely, a decrease in the temperature of the gas causes anticlockwise rotation of the shaft and electric contact to be made between the conacts 12 and the members 14. When actuated by a change in pressure, the three bimetallic elements are replaced by three Bourdon tubes 52, Fig. 9, supplied with the pressure fluid whose pressure is being controlled through a nozzle 59 and mounted on a ring 56 which is secured to an insulating plate 57 by clamps 58 which permit relative adjustment between the ring and the plate. Otherwise the arrangement is similar to the temperature-actuated device. In another arrangement, the bimetallic elements are replaced by resilient leaf springs 72, Fig. 10, secured to a ring 73 having lugs 81 for attachment to an annular plate 78 of, e.g. melamine or silicone resin. An actuating member M arranged to coact with one of the springs exerts a tangential thrust on the shaft 71 to rotate it anticlockwise and break electric contact. On removal of the member M from contact with the spring, the resilience of the springs rotates the shaft clockwise to make electric contact. The member M may be actuated manually or in response to a change in pressure, temperature or humidity. In a modification, the control member 11 is provided with double contacts at either end and the stops 17 are replaced by contact members so that the switch may function as a double-throw switch.
