Abstract: 714,678. Fluid-actuated valves. FERRANTI, Ltd. March 26, 1952 [June 26, 19511. No. 2006/51. Class 135. [Also in Group XXXVII] A housing 10, which may be arranged in the passage extending from the tank to the conservator of a liquid-immersed electrical apparatus, contains a member 18 pivoted at 17 and having a portion 19 which is adapted to collect gas bubbles passing from the tank. When a certain amount of gas is collected, the balance of the member 18 is disturbed and it is rotated counter-clockwise through a limited angle so that'a circular mercury switch 24 secured thereto closes an alarm circuit. The gas is normally prevented from escaping by a ball 21 which rests in an opening 20, but when the member 18 is rotated the ball runs to the left in its cage and uncovers the opening, so allowing the gas to escape and the member 18 to return to its normal position. In a modification, Fig. 4, a vane 30 is attached to the member 18 and is formed of metal gauze which is permeable to normal liquid flow but is impermeable to surges which thus tilt the member 18 clockwise to close contacts 32. In a further arrangement, Fig. 5, the member 18 is arranged in a vertical channel 36 and the vane 30 is replaced by a surge-responsive part 37 on the opposite side of pivot 17 to the portion 19. The part 37 is permeable to normal liquid flow but not to surges or the gas bubbles. The pivot 17 may be arranged in the centre of the channel 36 in which case a deflector 41 is used to direct surges towards part 37. The member 18 may be restored by springs and/or gravity, and may carry a contact movable between two fixed contacts. Alternatively, it may carry a circular magnet co-operating with a circular magnet outside the housing so as to operate an external mercury switch. The member 18 may be arranged to rock in the same direction but through different angles in response to surges and collection of gas.

Title: New pyrazolones and process for their manufacture
Filed: 1954-01-26
Abstract: The invention comprises pyrazolones of the formula <FORM:0754660/IV(a)/1> where R is a benzene residue and X is the acyl residue of an organic sulphonic acid.  These are prepared by condensing hydrazines H2N-NH-R-SO3-NH-X with suitable ring-closing agents, e.g. diketene or acetoacetic esters or amides.  Preferably the reaction is carried out with methyl or ethyl acetoacetate in an aqueous alkaline medium at the boiling point.  When acetoacetic amide is used, however, the medium is preferably neutral or weakly acid. An organic solvent may also be used.  The hydrazines can be prepared from the corresponding amines by diazotization and reduction. Examples show the preparation of 3-hydrazino - benzenesulphon - (N - benzenesulphonyl)-amide and 4-hydrazino-benzenesulphon - (N - ethanesulphonyl) - amide, and ring closure with an acetoacetic ester to 1-phenyl-3-methyl - 5 - pyrazolone - 31 - sulphon - (N - benzenesulphonyl) - amide and - 41 - sulphon - (N-ethanesulphonyl) - amide respectively.  Other products are mentioned in which R contains chlorine and methyl substituents, and X may also be chlorobenzenesulphonyl or dichlorobenzenesulphonyl.  It is stated that in general the aromatic nuclei may contain non-solubilizing substituents such as alkyl, alkoxy, nitro or halogen.ALSO:Azo dyes are made from pyrozolones of the formula <FORM:0754660/IV(c)/1> where R is a benzene residue and X is the aryl radical of an organic sulphonic acid.  Thus, diazotised aniline may be coupled with the compounds (1) R=m-phenylene, X=benzenesulphonyl, and (2) R=p-phenylene, X=ethanesulphonyl.  Many other suitable pyrazolones are mentioned.
