Title: Improvements in or relating to the removal of hydrogen sulphide from liquids
IPC: C10K1/12
Filed: 1933-06-21
Abstract: Hydrogen sulphide is removed from liquids, e.g. aqueous liquids employed in the scrubbing of gases or gas-holder water, by passing a stream of oxygen or air through a mass of porous material on which a catalyst is supported and simultaneously causing the liquid to flow over the porous mass.  The hydrogen sulphide is oxidized to sulphur. The catalysts include oxides or hydroxides of titanium, vanadium, chromium, manganese, elements of the iron group, molybdenum, tungsten, or cerium, iron oxide or hydroxide admixed with the oxide or hydroxide of chromium, manganese or molybdenum, chromium oxide or hydroxide admixed with the oxide or hydroxide of manganese, or iron or chromium oxide or hydroxide admixed with the oxides or sulphides of mercury, lead or copper as a promoter.  Suitable porous supports are coke, pumice and like granular substances.  The process may be employed in the regeneration of spent alkaline gas scrubbing solutions such as aqueous potassium carbonate.  If desired, the bulk of the hydrogen sulphide may be removed from the liquors before applying the present process.  The Provisional Specification is not restricted to the employment of catalysts on a porous support; it describes also the employment of catalysts themselves in a granular form and processes in which the bulk of the hydrogen sulphide is removed from the liquors by treatment with carbon dioxide and boiling before applying the present process.  Specifications 190,119 and 293,592, [both in Class 90], are referred to.ALSO:Hydrogen sulphide is removed from liquids, e.g. aqueous liquids employed in the scrubbing of gases or gas-holder water, by passing a stream of oxygen or air through a mass of porous material in which a catalyst is supported and simultaneously causing the liquid to flow over the porous mass.

Title: Control devices for internal combustion engines
IPC: F02M7/11
Filed: 1961-05-17
Abstract: 917,130. Carburetters. HONDA, S. May 17, 1961 [June 13, 1960], No. 18047/61. Class 7(3) A control device for an internal-combustion engine comprises an air vent in the outside wall of an intake pipe and a positive pressure extraction pipe disposed to the outside opposite the air vent and separated from it by a small gap communicating with the outside atmosphere, the arrangement being such that upon a positive pressure inside the intake pipe, gas is ejected from the vent so as to cross the gap and be injected into the positive pressure extraction pipe whereas upon a negative pressure in the intake pipe the outside air is chiefly sucked into the intake pipe via the gap without a substantial decrease in the positive pressure in the extraction pipe. The opening and closing of the inlet valve of the internal-combustion engine causes negative and positive pressure impulses in the suction pipe 2, Fig. 3, of the carburetter, the effect increasing as the engine speed increases. A pipe 7 is separated from an air vent 6 by a gap 9 adjustable by means of a nut 8. Negative pressure impulses cause air to be sucked through the vent 6 from the outside, whereby no significant pressure decrease occurs in the pipe 7. Positive pressure impulses, however, pass across the gap 9 into the pipe 7 and create a positive pressure therein. This positive pressure is directed by a flexible tube 11 to the float chamber 1 of the carburetter to accelerate the flow of fuel from the main jet and thereby prevent fuel shortage at high engine speeds caused by the tendency of the positive pressure impulses to reduce the fuel flow from the main jet. The positive pressure may also be applied to the fuel tank. More than one positive pressure extraction device may be provided. In the carburetter shown in Fig. 4, a compression spring 36 acting through a rack and pinion keeps a choke valve 22 in the closed position when the engine is idling, so that a sudden opening of the throttle valve 21 does not result in any appreciable fall in negative pressure at the pilot jet 29; in addition greater suction occurs at the main jet 23 and causes fuel flow therefrom. This prevents a temporary weakness of mixture which would stall the engine or retard its acceleration. As the engine accelerates a positive pressure is developed in the pipe 7 and acts on a piston 34 to open the choke valve 22.

Patent GB-747189-A (GB)
Title: Ethers of alpha-glycerylamine
Filed: 1953-07-01
Abstract: The invention comprises as new products gamma alkoxy ethers of alpha-glycerylamine having the formula <F\1> in which R is a hydrogen atom or a methyl group and n is 1 or 2.  They may be prepared by reacting in the liquid phase an alkoxy glycidyl ether having the formula <FORM:0747189/IV(a)/1> with ammonia, R being as defined above.  The ether is generally added slowly to an aqueous solution of ammonia although any other solvent for the ammonia may be used.  The reaction is preferably carried out at 10 DEG  to 60 DEG  C.  In another method the corresponding alpha glyceryl chlorhydrin (CH3(OC2H3R)nOCH2CHOHCH2Cl) instead of the glycidyl ether is reacted with ammonia in the liquid phase.  In examples: (1) the gamma-(methoxyethyl) ether of alpha-glycerylamine is obtained by adding the glycidyl ether of methoxy ethanol to aqueous ammonia, cooling to maintain the temperature at not more than 35 DEG  C. and when the reaction is complete heating to expel unreacted ammonia, removing water by distillation in a fractionating column at reduced pressure and then fractionally distilling the residue to yield the glycerlamine ether; (2) the same product is obtained as in (1) by heating a mixture of gamma-(methoxyethyl) ether of alpha-glycerylchlorhydrin and an aqueous solution of ammonia to 60 DEG  C. for three hours, cooling, adding an aqueous concentrate of sodium hydroxide, removing unreacted ammonia and water as in (1), filtering to remove salt, and then fractionally distilling the product to yield the glycerylamine ether; (3) gamma-(methoxyethoxyethyl) ether of alpha-glycerylamine is obtained by reacting methoxyethoxyethyl glycidyl ether with aqueous ammonia by a procedure similar to (1); (4) and (5) gamma-(2-methoxypropyl) ether of alpha-glycerylamine and gamma - (2 - methoxy - 2 - propoxypropyl) ether of alpha-glycerylamine respectively are obtained by reacting (2-methoxypropyl) ether of glyceryl amine (mixed isomers) and the glycidyl ether of dipropylene glycol monomethyl ether (mixed isomers) respectively with aqueous ammonia by a procedure similar to (1).  It is stated that some secondary amine may also be formed in (3) and (4).  The products are stated to be useful as soap formers in cosmetic compositions and the amide derivatives formed by reacting the products with stearic, lauric, palmitic, or oleic acid exhibit surface-active properties and are useful as non-ionic detergents, dispersants and emulsifying agents.  The alkoxy glycidyl ethers used as starting materials may be prepared by adding a monomethyl ether of a glycol to epichlorhydrin at a temperature not above 80 DEG  C. for about two hours to form the glyceryl chlorhydrin ether of the glycol ether which is then reacted with caustic soda to form the corresponding glycidyl ether; thus epichlorhydrin and methoxy ethanol react to give the glyceryl chlorhydrin ether of methoxy ethanol which on treatment with caustic soda yields the glycidyl ether of methoxy ethanol.
