Title: Preparation of vinyl thioethers
IPC: C07D333/18
Filed: 1956-07-03
Abstract: A process for the preparation of a vinyl thioether comprises bringing acetylene and a monoisothiuronium salt together in a liquid medium which is a solvent for said salt and which has dissolved therein a strongly basic compound of an alkali metal i.e. a compound having a basicity comparable with that of sodium hydroxide) as catalyst and subjecting the system to an elevated temperature and a pressure not less than atmospheric to bring about reaction between the salt and acetylene, said salt containing an S-substituent which is an alkyl, cycloalkyl or substituted alkyl group and not being decomposed by said strongly basic compound, said strongly basic compound being present in an amount sufficient to provide at least about one mol. of free base per mol. of said salt.  In a modification of the above process a bisisothiuronium salt which contains an organic group attached to the two sulphur atoms by aliphatic carbon atoms is employed as starting material and about two mols. of free base per mol. of bis salt are required.  Specific products of which the preparation is described include diethylamino-, ethyl-, di-methylaminoethyl-, N-methylaminoethyl-, 2-aminoethyl, 3 - aminopropyl -, dimethylaminoisopropyl -, butyl -, sec. - butyl, tetradecyl-, cyclohexyl -, benzyl -, thenyl -, phenoxyethyl, tetrahydrofurfuryl - and 2 - methyl - 4 - thiazolylmethyl vinyl sulphides and 1,4-bis (vinyl-mercapto) butane. 2-Imino-3-methyl-1,3-thiazoline is obtained as by-product in one process.  In general the products may bee oxidized with aqueous hydrogen peroxide to form sulphoxides or sulphones or reacted with cyclopentadiene or other conjugated unsaturated compounds. N-methylaminoethyl vinyl sulphide may be re-acted with methylene oxide, with cyanogen chloride to form the corresponding cyanamide or with formaldehyde to give a methylol compound.  Isothiuronium salts employed as starting materials are obtained by reacting thiourea with an appropriate organic halide e.g. alkyl, cycloalkyl, aralkyl, alkoxyalkyl, cycloalkoxyalkyl, aryloxyalkyl, aralkoxyalkyl, aminoalkyl which may contain one or two N-alkyl substituents, aminoaralkyl and heterocyclic substituted alkyl halides, haloalkane sulphonic and halocarboxylic acids, 1 - (2 - chloroethyl) - 2 - imidazolidinone, tetrahydropyranylmethylchloride and 2 - methyl - 4 - chloromethylthiazole.  Dihalides e.g. alkylene dibromides or xylylenyl dihalides, are employed to form the bis-isothiuronium salts.ALSO:N-Methylaminoethyl vinyl sulphide is polymerized to give homopolymers and copolymers with other polymerizable vinylidene compounds.ALSO:Fungicidal compositions comprise as active ingredient N-methyl-, N-ethyl-, N-butyl-, N-benzyl- or N-cyclohexyl aminoethyl vinyl sulphide or N-methylaminopropyl vinyl sulphide.

Title: Improvements relating to the manufacture of water gas
IPC: C10J3/00
Filed: 1946-07-15
Abstract: 614,489. Water gas plant. HUMPHREYS & GLASGOW, Ltd., and PHILLIPS, I. H. July 15, 1946, No. 21188. [Class 55 (i)] A water gas installation comprises two generators 1 with jacket low pressure boilers 1a which are connected through non-return valves 6 and a pressurecontrolled reducing valve 7 with a main 2 leading exhaust steam to the generators from auxiliaries 5 receiving steam from high-pressure waste heat boilers 3. A connection through a reducing valve 8 either before or after reducing valve 7 enables steam from boilers 3 to pass to main 2. When both generators are using steam for gas making a fall of pressure in main 2 causes valve 7 to admit steam from the jacket boilers, and valve 8 opens to admit steam from boilers 3 when the pressure in the jacket boilers has reached a determined minimum. The high pressure steam may be supplemented from a source 4a if necessary. In the case of a single generator installation, that part of the exhaust steam not utilizable for feedwater heating passes to atmosphere or is condensed during the blow period.

Title: Improvements in throw-off mechanism for platen presses
IPC: B41F1/60
Filed: 1929-07-13
Abstract: 331,402. Frauenberger, C. F. July 13, 1929. Impression adjustments; tripping- arrangements. - A platen presser for creasing, cutting, and like operations is constructed with a rocking platen 3 moved towards a fixed forme member 2 by connecting rods 4, the platen being carried on a shaft 5 journaled in eccentric sleeves 6 mounted in the ends of the connecting rods. To adjust the pressure of impression, the sleeves 6 are formed with projections 7 connected by an adjuster arm 8, and a spring-pressed catch 21 at each end of the arm 8 is engaged by a notch 15 in an adjustable pawl 13 to adjust the sleeves 6 to the desired position. The pawls 13 can be secured to racks 12 by screws engaging nuts movable in undercut grooves in the platen, and the impression pressure is dependent upon the position of the pawls 13. When it is desired to trip the impression, the catches 21 are disengaged from the pawls 13 by means of a trip-lever 50 which can be set by an electromagnet 87 to engage a trip arm 43 connected bv a link 41 to a lever arm 30 on a shaft 26 which is fitted with latch-lifting fingers - engaging pins on the catches 21. The projections 7 are thus released and the eccentrics move to throw-off the impression, the members associated with the shaft 26 moving at the same time from the dotted line position, Fig. 1, to the full line position. To untrip the press, the trip shaft 26 is moved anticlockwise, by the action of a cam 63 on a pivoted abutment 62 operated by a foot, bar 64 against the pressure of a centring spring 65. The cam 63 acts on a roller 36 on a lever 34 connected bv a link 32 to the arm 30 on the shaft 26, and also the cam 63 acts on a roller 38 in a bearing member 27 carried by the adjuster bar 8. and restores the bar 8 to its normal position. The members 50, 63 are adapted to effect their operations independently of the position to which the pawls 13 are set, so that the tripping actions are independent of the impression adjustments. The electromagnet 87 is arranged in an electric circuit similar to that described in Specification 308,525 which describes a. machine with a pressure-adjustment device similar to that of the present application. This circuit includes a stopping device controlled by the delivery grippers of the press.

Title: An Improved Method of Producing an Explosive Mixture and a Carburettor therefor.
Inventor: ENSIGN ORVILLE HIRAM
IPC: F02M21/00
Filed: 1918-12-30
Abstract: 121,964. Ensign, O. H. Dec. 29, 1917, [Convention date]. Vaporizers, external.-Part of the heavy fuel and air supplied through the carburettor is electrically ignited and burnt in a separate chamber, and the heated gases thus formed pass through a common throttle with the rest of the mixture into a mixing- chamber. The fuel and air pass downwards from the carburettor through a chamber 1; any fuel remaining liquid is drawn through a grating 10 into the combustion chamber 14, where it strikes a deflector 13 and, after being burnt, passes up a tube 15 to the mixing-chamber 9. Air or mixture is also drawn into the combustion chamber by means of a passage 53 having an adjustable opening into the chamber 1. Ignition is effected in the chamber 14 by a sparking-device 24. The underside of the deflector 13 is covered with refractory material 49. A throttle 8 fits over the tube 15 and the mixture passage 6, and has notches 32, forming ports, which can be closed bv sliding blocks 30, 30<1>. The block 30<1>, controlling the supply from the passage 6 when the throttle is closed, is operated by hand; the block 30, controlling the supply of heated gases, may also be operated by hand, but is preferably actuated by a thermostat. When the apparatus is cold, a spring 35 withdraws the block 30, so opening the port 32. As the apparatus becomes heated, the thermostat 41 expands and forces the block 30 inwards, tending to close the port 32. The thermostat is contained in a chamber heated bv gases passing from the tube 15. For starting, lighter fuel is supplied from a tank c to a receptacle 18, from which it flows through the grating 10 into the combustion chamber. The lower part of the combustion chamber is covered by a casing 77 through which air passes to a pipe 79 and the main air inlet 2. A small amount of air is admitted direct to the combustion chamber through a hole 74.

Title: Improvements in carburetters for internal combustion engines
IPC: F02M69/04
Filed: 1939-07-27
Abstract: 531,589. Spray carburetters. GUIDI, R. July 27, 1939, Nos. 21830 and 21831. Convention dates, July 27, 1938 and Nov. 28, 1938. [Class 7 (iii)] Air entering at 14 past a spring-controlled throttle 15 is carburetted by one or more jets 26, 26<1>, the opening of one 26 of which is regulated from the accelerator connection 38 to the throttle, the fuel being supplied from a chamber 2 which is fed by a pump and is connected by an orifice to a chamber 5 having a spring-pressed diaphragm to absorb the fluctuations of pressure caused by the fuel pump. The jet 26 is controlled by a needle valve 23, Fig. 4, seating on a calibrated orifice in a replaceable disc 24, the valve being connected to a spring- pressed diaphragm 35 and having its lift limited by a stop 41 adjusted by an arm 40 connected to the accelerator rod 38. Air enters through the hollow bore of the valve 23, and fuel is supplied to the chamber 31 through connections 34, 33 and passages 32. The pressure of the fuel on the diaphragm 35 opens the valve 23, and the fuel flows through passages 37 to the nozzle. When a second jet 261 is provided for slow running, this is controlled by a similar valve, which, however, is pressed on to its seat by the spring acting on the diaphragm, and has its lift limited by an adjustable screw stop, the entry of air through the bore of the valve being also regulated by a screw threaded needle valve. Secondary slow-running air is admitted through an adjustable orifice 67. In a modification, the nozzle 26<1> is omitted, and the stop 41 for the fuel valve is adjusted to leave a slight play for slow running when at its innermost position, fuel being cut off for stopping the engine by a second Bowdencontrolled stop acting on the valve 23. The chamber 5 for regulating the fuel pressure may also be omitted. ,
