Title: Improvements in change speed gear operating mechanism
IPC: B62M25/04
Filed: 1923-03-16
Abstract: 213,107. Bailey, S. L. March 16, 1923. Controlling variable-speed gearing.-In controlmechanism for change-speed gearing upon a motor-cycle operated by the rider's foot, a movable plunger G is provided to engage the gear lever A and stop it in a proper intermediate gear position. The lever A to be moved over quadrant E, Fig. 1, has an ordinary locking spring bolt C adapted to engage three notches E<2> in the, quadrant. A spring slider F, Fig. 2, carried by the lever is pulled by a cord F<3> so that an incline F<4> disengages the bolt C. As the lever moves upwards, a second spring bolt D strikes the lower side of the plunger G, which is in the form of a stout stud with a wide head guided by and moving freely in an arc-shaped slot E<3> The plunger G stops at position 2, when the lever A is in proper mid position X. To move the lever farther, a bigger displacement is given to the slider F until a second incline F<5> raises the bolt D clear of the plunger G. The lever A is then moved on by foot pressure to final position Y and locked on release of the slider F. On the downward movement, if the intermediate position X is required, the bolt D is left projecting so as to pick up the plunger G on its upper edge. When the plunger G steps at the lower end of the slot E<3>, the lever A is in position X. Further movement is obtained by disengaging the plunger by raising the bolt D as before.

Title: Improvements relating to valves and operating means therefor
IPC: F16K31/126
Filed: 1946-03-12
Abstract: 615,459. Valves controlled by auxiliary valves. PROSPERITY CO., Inc. March 12, 1946, No. 7647. Convention date, July 20, 1945. [Class 135] [Also in Group VIII] In a control valve, e.g. for an ironing press, in which the valve member is operated by the movement of an actuating disc under the action of fluid pressure, a resilient holding disc, free at its edge and located in a chamber having a concave wall, is adapted on admission of pressure fluid to the chamber to flex against the concave wall, this flexing movement being transferred to the actuating disc to hold the latter in the operated position. On actuation of a two-hand control constituted by two series-connected valves 43, 44, Fig. 1, compressed air entering the inlet port 17 of a chamber 15 forces a flexible actuating disc 18 against the concave wall 16 of the chamber, thus closing an exhaust valve 5. and opening an inlet valve 2 to admit compressed air to a cylinder 12, having a piston connected to the movable portion of the press. Near the end of the power stroke, the piston uncovers a port 30, and compressed air passing through a pipe 27 to the chamber 24 operates the holding disc 23 which is connected to the actuating disc by a member 28, so that on release of the valves 43, 44 and the consequent exhaustion of the pressure in the chamber 15, the actuating disc, and therefore the piston, are held in their operated positions, until the compressed air in the chamber 24 is exhausted through a port 33 by the opening of either a manually-actuated release valve 31 or a time-controlled release valve 35. In a modification, the actuating disc is rigid.

A cut - off mechanism for a continuous rod machine comprises a ledger, formed by a rotating disc 17, and a rotatable helical knife blade 13 with its axis skewed to the cigarette rod 22 of the helix angle so that the rod is cut squarely, the knife being rotated at a speed such that the part in cutting engagement with the rod 22 has a component of velocity in the direction of travel of the rod 22 equal to velocity of the rod; the radius of the cutting edge of the knife increases from its leading end to its trailing end and its circumferential extent from the point 14, Fig. 2, where it contacts the rod to the point 15 where it leaves the rod is less than a complete revolution but greater than three quarters of a revolution. The ledger comprises a wheel 17 with a peripheral speed equal to that of the rod and having a peripheral groove 18 into which the rod 22 is guided by a tapered guide 24, the groove 18 having notches 20, spaced apart by a cigarette length, to receive the knife. As the knife, which is preferably of tungsten carbide, rotates, its cutting edge travels with the rod, simultaneously penetrating deeper into the rod until it enters one of the grooves 20 and completes the cut. A cutaway portion 16 at the trailing end 15 of the knife permits the release, at the end of each cut, of tension or compression introduced in the rod by any slight discrepancy between the speed of the rod and of the cutting edge.

Title: Manufacture of monoazo-dyestuffs capable of being chromed
IPC: C09B45/16
Filed: 1943-05-14
Abstract: Monoazo dyes, capable of being chromed in the dyebath or on the fibre, to produce dyeings of good wet-fastness and light-fastness on wool, are obtained by coupling a diazotised 2-aminophenol-6-sulphonic acid, substituted in 4-position by a cycloalkyl residue or by an alkyl residue containing 3 to 8 carbon atoms, with a pyrazolone free from sulphonic or carboxylic acid groups.  Specified diazo components are the 4-isopropyl, 4-tert.-butyl, 4-n-butyl, 4-tert.-amyl, 4-(a  : a  : g  : g -tetramethylbutyl) and 4-cyclohexyl derivatives of 2-aminophenol-6-sulphonic acid, and specified coupling components are 3-methyl-5-pyrazolone, 1-phenyl-3-methyl-5-pyrazolone, 1-(21-methyl)-phenyl-3-methyl-5-pyrazolone, 1-phenyl-3-methyl-5-pyrazolone-31- or 41-sulphonamide, 1-(21-chloro) phenyl-3-methyl-5-pyrazolone, 1-(31- or 41-chloro)-phenyl-5-pyrazolone-3-carboxylic acid ethyl ester, 1-(31-chloro)-phenyl-5-pyrazolone-3-carboxylic acid amide or butylamide.  Examples relate to the production of the dyestuffs: (1) 4-isopropyl-2-aminophenol-6-sulphonic acid --> 1 - phenyl - 3 - methyl - 5 -pyrazolone; (2) 4-n-butyl-2-aminophenol-6-sulphonic acid --> 1-(31-chloro)-phenyl-5-pyrazolone-3-carboxylic acid ethyl ester; (3) 4-(a  : a  : g  : g -tetramethylbutyl)-2-aminophenol-6-sulphonic acid --> 3-methyl-5-pyrazolone.  A table is also given showing the tint of the chromed dyeings of the dyestuffs from various combinations of components.  The p-alkylated and cycloalkylated o-aminophenolsulphonic acids employed as diazo components are obtainable from the corresponding alkyl- or cycloalkyl-phenols by sulphonation (e.g. with chlorosulphonic acid in an organic solvent such as chlorobenzene or carbon tetrachloride or with 98 per cent sulphuric acid), nitration (e.g. with 62 per cent nitric acid) and reduction (e.g. with iron by the B<\>aechamp method). 1-Phenyl-3-methyl-5-pyrazolone-31- and 41-sulphonamides are obtainable by condensing 3-and 4 - hydrazinobenzenesulphonamide with acetoacetic ester.  1-(31- and 41-Chlorophenyl)-5-pyrazolone-3-carboxylic acid ethyl esters are obtainable by condensing 3- and 4-chlorophenylhydrazine hydrochloride with sodium oxalacetic ester in the presence of sodium bicarbonate by boiling in benzene.  1-(31- and 41-Chlorophenyl)-5-pyrazolone-3-carboxylic acid ethyl esters are obtainable by condensing 3- and 4-chlorophenylhydrazine hydrochloride with sodium oxalacetic ester in the presence of sodium bicarbonate by boiling in benzene.  1-(31-Chlorophenyl)-5-pyrazolone-3-carboxylic acid amide and butylamide are obtainable by treating the corresponding ethyl ester with ammonia at 50 DEG  C. or with butylamine at 60 DEG  C.

Title: Improvements in or relating to electric circuit interrupters having arc-extinguishing arrangements
IPC: H01H33/98
Filed: 1944-04-25
Abstract: 593,575. Fluid-blast switches; automatic circuit-breakers. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. April 25, 1944, No. 7725. Convention date, March 19, 1942. [Class 38(v)] A fluid-blast circuit-breaker has an insulating blast conduit 11 which includes an electromagnetically operated control valve 13 and is closed by valve 35 when the pressure inside the arcing chamber 17 exceeds that in the conduit. A cylinder 19 is closed by metal plate 21, the central contact aperture 23 of which co-operates with contact 73 fitted to piston 83. The movable contact 33 is opened by the downward movement of spring-urged piston 43 when the latch 51 is actuated by electromagnet 53, which also operates valve 13. The breaker is closed by passing fluid through valve 45 to actuate piston 43. Arcing horn 65 is connected to contact 33 through cable 59 and is placed diametrically opposite to arcing horn 67 which, extends upwards inside the cylinder and is connected to contact 73. The fixed contact 31 is connected through rod 95 to the plate 21. When the contacts 31, 33 are parted, the arc is blown by a fluid blast from conduit 11 onto gas-evolving insulating plates 85. The pressure in the chamber 17 is increased by the gas produced until piston 83 is lowered, thereby drawing another arc, which is in series with arc 90. This second arc is extinguished by the glas blast, thus breaking the circuit. Spring 75 recloses contacts 23, 73 when the pressure subsides. Fig. 4 shows a modification in which the arc is moved onto the gas-evolving plates 147 by magnetic plates 145 disposed between them. The second arc is formed between contact 123 and nozzle 141. A piston 127, fitted to the contact 123 and moving in a cylinder 129 provided with limiting stops 139, is biased out of the cylinder by pivoted spring guides 137 which engage pins 133 secured to piston 127. The nozzle 141 is connected to the fixed contact 105 by rod 143. In a further modification, Fig. 6 (not shown), the magnetic plates 145 are replaced by an external blow-out coil. In this modification, only one arc is formed, this being moved against the gas-evolving plates by the coil and then being extinguished by the rush of gas which occurs when the vent is opened. Fig. 9 (not shown) incorporates this modification with the contact and fluid blast mechanism of Fig. 1. The invention is also stated to be applicable to liquid blast extinguishing means in which case liquid is placed in the pressure chamber and the gas-evolving plates dispensed with.

Filed: 1953-03-20
Abstract: 732,858. Phase and frequency changing; supply systems for welding arcs. MATTSSON, K. H. March 20, 1953 [March 20, 1952], No. 7751/53. Classes 38 (2) and 38 (4). A system for deriving a zero phase sequence current from a three-phase supply system in which the three-phase voltage is fed into the star or inter-star connected primary winding 2 of a saturable transformer and a single phase output having three times the supply frequency taken from the secondary winding 3 thereof, is characterized in that the secondary winding is arranged as a star connected winding on the same core columns as the primary winding and in that a star connected condenser system 5 is connected to the secondary winding, the condenser system and the transformer being so dimensioned that the reactive power is compensated with regard to the fundamental frequency of the supply as well as to the third harmonic thereof, the output 7 being taken from the two zero points of the secondary circuit. Boosting windings 4, which may be parallelly or serially connected, may be connected in the output circuit to boost the voltage thereof. The boosting windings 4 may or may not be on the core columns not occupied by the primary and secondary windings. Regulating windings may also be accommodated on the core columns carrying to boosting windings and in association with a variable impedance allow for adjustment of the no-load voltage, short-circuit current and load characteristic of the secondary circuit. A switch may be associated with the output circuit and periodic operation of this switch can forcibly modulate the output of the secondary circuit. In certain cases it may be preferable to inject an E.M.F. of selected value and frequency into the circuit containing the regulating windings 8. In a further embodiment the primary and secondary windings may be combined into single windings in the form of an auto-transformer.

Title: Enolic ethers of adipic dialdehydes and process for their preparation
IPC: A61P31/04
Filed: 1968-02-16
Abstract: 1,205,618. Enolic ethers of adipic dialdehydes. UGINE KUHLMANN. 16 Feb., 1968 [9 March, 1967], No. 7791/68. Heading C2C. New enolic mono- and diethers of adipic dialdehydes of the general formulµ wherein R is the same or different and represents hydrogen, C 1-4  alkyl or optionally substituted phenyl and R<SP>1</SP> represents C 1-4  alkyl optionally substituted by halogen, hydroxy or nitrile, are prepared by heating a mono- or diether of 1,5-hexadiene-3,4-diol of formulae or their mixtures, to high temperatures to realise a Cope transposition. The process may be performed in the liquid phase in an inert, thermally stable solvent such as an aliphatic or aromatic hydrocarbon or an ether such as diphenylether, at atmospheric pressure and at the boiling point of the mixture. 0À01-1% of a polymerization inhibitor may be included, e.g. hydroquinone, monomethyl ether of hydroquinone, t-butyl-catechol, p-phenylene diamine or a copper salt. The heating time for the process may be 1/3-5 hours. The process may also be performed in the gaseous phase by passing the vapours of the starting material diluted if desired in an inert gas such as nitrogen, argon or CO 2 , into a duct which may contain matter inert to the vapours. These novel compounds may be used to generate the corresponding adipic dialdehydes since they are easily hydrolysed in a slightly acidic medium and thus may be made as disinfectants for water, textiles as bactericides, as reticulating and insolubilizing agents for proteins or polyhydroxylated polymers, in textile stiffening, paper treatment, reticulation of polyvinylic alcohols or other hydroxylated polymers. Also they may be used as monomers to carry out polymerization or copolymerization reactions with other vinylic monomers and are raw materials for the preparation of many di- or polyfunctional compounds such as 1,6-hexanediols and 1,6- diaminohexanes.
