Filed: 1958-04-11
Abstract: The invention comprises N-substituted benzo triazoles of the general formula <FORM:0885843/IV (b)/1> wherein R represents alkyl, alkoxy, carboxy, carbalkoxy, dialkylamino, halogen or NO2, R1 represents an alkyl, haloalkyl, or dialkylamino group and n is 0, 1 or 2.  They may be prepared, for example, by reacting compounds of the general formula ClSO2-R1, R1 being as defined above, with benzotriazole or an appropriate R-substituted derivative thereof in aqueous alkali or in an inert solvent to which is added an acid-binding agent, or with an alkali-metal compound of the triazole.  Alternatively, they may be prepared by reacting an appropriate o-nitro aniline with a sulpho-chloride ClSO2-R1, reducing the resulting sulphonic acid-o-nitranilide to the corresponding amino compound and reacting this amine with nitrous acid.  The products are fungicidal agents (see Group VI).  In examples, there are prepared, by the first method, benzotriazoles in which (1) R1 = dimethylamino-, n=0, (2) R1=CH3-, n=1 and R=5- or possibly 6-NO2-, 5- or possibly 6-chloro-, 5-CH3-, 5-carbethoxy- and 5-carboxyrespectively and (3) R1=chlormethyl-, n=0; and by the second method, benzotriazoles in which R=5-methoxy-, n=1 and R1=CH3- or ClCH2-.  A mixture of N-C2-4 alkyl sulphonyl benzotriazoles is also described.ALSO:Fungicidal compositions comprise in or on a carrier an N-substituted benzotriazole of the general formula <FORM:0885843/VI/1> wherein R represents alkyl, alkoxy, carboxyl, carbalkoxy, dialkylamino, nitro or halogen, n is 0, 1 or 2 and R1 represents alkyl, haloalkyl or dialkylamino.  Specified triazoles include those in which (1) R1=dimethylamino and n=0, (2) R1=CH3, n=1 and R=5- or possibly 6-NO2-, 5- or possibly 6-chloro-, 5-CH3-, 5-carbethoxy and 5-carboxy respectively; (3) R1=ClCH2- and n=0, and (4) R=5-CH3O-, n=1 and R1=CH3- or ClCH2-.  The active ingredients may be used in an organic solvent such as castor oil, carbon tetrachloride, ethylene dichloride, ethane tetrachloride, naphthalenes, solvent naphtha and aerosol solvents.  They may be used in aqueous emulsions or dispersions suitably prepared by diluting with water a concentrated solution of the triazole in, for example, acetone or dimethyl formamide.  They may also be used with solid diluents such as chalk, calcium phosphate, kaolin, kieselguhr, bentonite and wood or cork powder.  Anionic, cationic or non-ionic wetting agents may be present, e.g. polyoxyethylated benzyl hydroxy diphenyl.

Title: Electric rail bond
IPC: B60M5/00
Filed: 1924-05-13
Abstract: 219,940. Embru - Werke Akt. - Ges. July 31, 1923, [Convention date]. Rail-bonds.-The conductor element is inserted into weldable terminal blocks each having a socket or orifice with a wide portion towards the entrance and being of seamless metal. Where it enters the block the conductor is of full cross section but by compression of the block the remainder is pressed flatwise. Prismatic blocks 2 are cut from a rolled iron bar having a convexity 3<1>, extending along each broad face, and a longitudinal bore. After inserting the end of a conductor 1 into one of these blocks pressure is so applied to the block that the metal of the convexities, except for the residual parts 3 which are also pressed but with less force, is driven inwardly around and' into the ends of the conductor. The blocks are welded in a somewhat inclined position, preferably to the heads of the rails, but if welded to the bases the part 3 is inclined to present an even surface. Specification 18493/02 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the conductor is not materially broadened by the compression. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a Hydraulic Lifting Apparatus
IPC: F15B11/22
Filed: 1967-03-14
Abstract: 1,174,809. Platform elevators. YAWATA IRON & STEEL CO. Ltd., and TOKYO KEIKI SIEZOSHO CO. Ltd. 14 May, 1967 [16 March, 1966], No. 11862/67. Heading B8H. [Also in Division F1] An hydraulic load lifting apparatus has a plurality of lifting cylinders 6-9 movable in synchronism by hydraulic fluid supplied by a main pump 1, the output of which is divided into separate streams by passage through a plurality of coupled motors M, one for each cylinder, the thus possibly slightly differing flow rates to each cylinder being automatically adjusted to the same rate by valves 10-13, each controlling the supply to a particular cylinder of additional fluid from an auxiliary pump 14. A solenoid operated changeover valve 15 allows the valves 10-13 to adjust the flow rate from the cylinder during lowering of the load. If any cylinder reaches its lowermost position ahead of the other cylinders, the creation of a vacuum therein is prevented by the opening of an associated non-return valve 17, 18, 19 or 20 to admit hydraulic fluid from a reservoir. In the event of any cylinder reaching its uppermost position ahead of the other cylinders the excess pressure is released through an associated non-return valve 21, 22, 23 or 24 and a relief valve 25. A low-pressure relief valve 32 may be connected so as to replace the relief valve 25 by operation of a solenoid valve 26, whereby fluid may be flushed from the apparatus without raising the load. Each cylinder has an individual solenoid valve 27, 28, 29 or 30 independently operable to supply hydraulic fluid from a further pump 31 or exhaust fluid for independent adjustment of the lifting cylinders. Differences in the extensions of the units are corrected by appropriate operation of the solenoid valves in response to displacement error signals emitted by synchronous motors.

Abstract: <PICT:0760517/III/1> <PICT:0760517/III/2> <PICT:0760517/III/3> In a process for the purification of water by distillation, a current of air is heated while flowing through duct 2 by employing mirrors 12 and 3 to concentrate the sun's rays 16 upon the duct, the heated air is passed into heat-insulated chamber 56, the water to be purified is sprayed into the chamber, air saturated with water-vapour is withdrawn from the chamber and is introduced into cooler 63 where purified water condenses.  The air is forced by fan 41, driven by windmill 1, through pipe 4 into duct 2 which extends along the focal axis of trough-like mirror 3 of parabolic section.  The duct 2 comprises a black tube 18 (Fig. 2) and a transparent covering 19, the air circulating in the annular spaces 20.  The assembly comprising mirror 3, duct 2 and pipe 4 can be rotated on horizontal shaft 6. One end of this shaft is mounted in bearing 7 which is supported on wheeled-carriage 9; and an articulated joint 8b permits rotation, in a horizontal plane, of the mirror-duct assembly relatively to the fixed bearing 8.  Disposed above the parabolic mirror is a series of plane mirrors 12 parallel to one another and reflecting on both faces, these mirrors being secured to a beam extending from shaft 14, which rotates in bearings carried by pylons 15. Each mirror 12 may be rotated about an axis at right angles to shaft 14.  As the sun travels across the sky the adjustment of the mirrors is effected manually or, alternatively, by photoelectric cells responsive to the action of the sun's rays.  The heated air passing from duct 2 is delivered to nozzle 55 from which it is discharged into chamber 56. The water to be purified is finely atomized into the chamber by part of the hot air.  Air saturated with water vapour leaves the chamber through conduit 61, and is introduced into cooler 63 which comprises a narrow labyrinth whose walls are cooled by feed-water passing upwardly through the cooler.  The water condensed from the air-stream passes through a bed 67 of sand and stones for discharge through outlet 68.  The air leaves the condenser through pipe 42, and returns to fan 41 for recirculation.  The unevaporated water collects in the lower part of chamber 56, and is removed through channel 70.  This water may be evaporated in a tank (not shown) by the heat of the sun in order to separate the mineral elements therefrom.
