Title: Improvements in control devices for gaseous fuel burning appliances
IPC: F16K1/30
Filed: 1956-09-18
Abstract: 798,369. Valves. AKTIEBOLAGET BAHCO. Sept. 18, 1956 [Sept. 19, 1955; Oct. 10, 1955], No. 28507/56. Class 135. A device for controlling the pressure of gaseous fuel delivered from a container 1 comprises a valve closure member 4 urged by a light spring 5 towards a seat 3 and having a stem 18 engageable by an abutment 19 having screw - threaded engagement with a plunger 9 which is acted upon at its lower end by the delivery pressure in opposition to the loading of a spring 10 and is rotatably adjustable by a knob 12. The abutment 19 is permitted to move axially but prevented from rotating by a pin 16 engaging grooves 17 in the housing. With the parts in the position shown, in which a pin 13 carried by the knob 12 is in engagement with a fixed pin 14, the abutment 19 is withdrawn from the stem 18 so that the valve member 4 may close under the influence of its spring 5 but when the knob 12 is rotated by one revolution to bring the pin 13 again into engagement with the pin 14 the abutment 19 opens the valve member 4 to permit the delivery of gas which, acting on the plunger 9 causes closing movement of the valve member should the delivery pressure exceed the value determined by the setting, through a cap 11, of the spring 10. In a modification, the abutment 19 carries a conical closure surface intermediate its lower end and its threaded portion for engagement with a seating in the casing when the control knob is turned to the closed position. In a further modification the axis of the plunger 9 is at right angles to that of the valve member 4 and the abutment member, having screw-threaded engagement with the plunger, terminates in an inclined surface which engages a plunger arranged coaxially with the valve member 4. In this modification the outlet, formed as a burner mouthpiece, is situated at the upper end of the casing coaxially with the valve member 4.

Title: Process and apparatus for the catalytic hydrogenation of carbon monoxide
IPC: C07C29/152
Filed: 1949-11-08
Abstract: <PICT:0680821/III/1> In the synthesis of hydrocarbons and oxygen-containing derivatives thereof by the hydrogenation of carbon monoxide in a catalytic converter, the catalyst is indirectly cooled in sections by the evaporation of a liquid, e.g. water, each section being cooled independently of the other sections and the cooling of the sections being controlled to maintain a catalyst temperature which increases in the direction of flow of the synthesis gas through the converter.  The process is applicable for use with multiple or multi-tubular catalytic converters.  As applied to the multiplate converter, the catalyst is disposed between plates 2, gaseous reactants entering the converter at 3 and reaction products being withdrawn at 4.  The catalyst is cooled along its length to ensure a rise in temperature in the direction of gas flow, by three banks 5, 6, 7 of cooling tubes containing water, each bank being self-contained and connected to a steam drum 8, 9, 10.  Each drum is connected through a reducing valve 11 to a common pipe through which steam is withdrawn, the valves serving to control the pressure and hence the temperature in each bank of tubes so as to ensure that the catalyst temperature rises in the direction of gas flow.  When several converters are grouped together in parallel, the bank of cooling tubes serving corresponding zones of each converter are connected to the same steam generator.

Title: Improvements in the manufacture and production of hydrogen or gas mixtures containing hydrogen from hydrocarbons
IPC: C01B3/36
Filed: 1926-11-15
Abstract: 288,662. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Nov. 15, 1926. Hydrogen is produced by subjecting hydrocarbons or mixtures containing them to partial combustion with a limited amount of oxygen or gas richer in oxygen than air so that the resulting mixture still contains appreciable amounts of hydrocarbons, adding steam if not already prosent, and passing the mixture over a catalyst which at least converts the hydrocarbons into carbon monoxide and hydrogen, and if desired brings about the complete conversion of the hydrocarbons, carbon monoxide, and steam into carbon dioxide and hydrogen. In the former case the product is a mixture of carbon monoxide and hydrogen, in the latter case the carbon dioxide may be removed leaving pure hydrogen. The partial combustion may be replaced by a partial thermal decomposition effected by passing the gas through a heated tube. An alternative method of procedure consists in subjecting only a portion of the gas to combustion and mixing the product with the remaining untreated portion before passing it over the cataylst. Two stages of catalytic treatment may be employed, the first using a heat-resisting but less active catalyst such as nickel on fireproof maternal and the second a less resistant but highly active catalyst such as nickel activated by alumina or magnesia, or an activated nickel-iron catalyst. Sulphur compounds are preferalbly removed from the gas before treatment. According to an example, 44 cubic metres of coal gas containing 30 per cent. of hydrocarbons are partly burned with 11 cubic metres of oxygen and 12 kgs. of steam ; the product with the addition of 18 kgs. of steam is passed over nickel activated with alumina and finally over iron and chromium oxide. The reaction mixture consists chiefly of hydrogen and carbon dioxide. In a similar example the iron. chromium catalyst is omitted ; the product consists largely of hydrogen and carbon monoxide and may be mixed with water gas to give a mixture suitable for methanol synthesis Specification 231,218 is referred to.

Patent GB-356956-A (GB)
Title: Precipitation and treatment of cellulose derivatives
IPC: D01F2/28
Filed: 1930-09-26
Abstract: <PICT:0356956/IV/1> Cellulose compounds such as esters or ethers are freed from constituents of the reaction mixture by incorporating in the solution a substance which is capable of being abruptly gasefied at temperatures which will not injure the cellulose compound, and then carrying out the precipitation under such conditions that the product is disrupted by the large quantity of gas produced. The process is carried out by commingling one or more streams of the solution with one or more streams of a precipitant within a gastight chamber containing a centrifuge so that the cellulose compound is disrupted and delivered directly to the centrifuge. The disrupted condition of the product renders washing easy. Sulphur dioxide or ether may be used as the disrupting medium. The process is applicable to the manufacture of cellulose acetate, propionate, benzoate, or other cellulose esters or ethers.  The cellulose compounds may be treated in the solutions in which they have been formed.  In the case of cellulose acetate the solution may contain acetic acid, acetic anhydride, and sulphuric acid together with sulphur dioxide as disrupting medium, or if the solution has been subjected to hydration treatment, it may contain acetic acid, water, and sodium sulphate. Already isolated products may be treated by dissolving them in a liquid consisting of or containing sulphur dioxide or other disrupting agent.  As shown in the drawings, a closed pressure vessel 2 holds the cellulose ester solution containing sulphur dioxide which has preferably been brought almost to the point of coagulation by the addition of water.  The solution is forced under pressure through pipe 3 to a centrifuge 5 which is gas-tight except for the sulphur dioxide gas outlet 6.  The centrifuge has a closure cover 7 in the form of a truncated cone which is secured in a gastight manner to the stationary part of the centrifuge.  The pipe 3 terminates in a nozzle or head 9 which may be of the form described in Specification 346,824.  The nozzle has two other pipe connections 30, 31, connected respectively to a supply of water for precipitation, and to a supply of steam or other gas to serve as heating agent.  The cellulose ester solution is thus commingled with the precipitating liquid and with the heating medium, and the product is abruptly and evenly disrupted by the evolution of gas. The product is collected in the rotating basket of the centrifuge and the liquid such as water and acetic acid is extracted and drawn off through the pipe 19.  When the basket is full, the supply of cellulose ester solution is cut off and washing liquid is caused to enter by the pipe 10.  The washing liquid may contain sodium bicarbonate.  Specifications 306,531, 329,718, [both in Class 2 (ii), Cellulose &c.], also are referred to.
