Title: Improvements in traps for removing entrained water from compressed air pipe lines
Inventor: ALLEN ARTHUR COOPER
IPC: F16T1/14
Filed: 1951-02-08
Abstract: 709,722. Trapping water from compressed air pipe lines. STEWART-WARNER CORPORATION. Feb. 8, 1951, No. 3135/51. Class 64(2) A trap or receptacle for separating and automatically ejecting entrained water from compressed air flowing through a pipe line operates by a differential pressure set up by the normal flow of air through the trap through means responsive to a predetermined rise of water level in the receptacle to apply the differential pressure to open a water ejection valve. In the form shown in Figs. 1 and 2, air entering at 20 meets a baffle 32 having openings leading to an inner annular space having an outlet 36 connecting with a channel 58 that passes to the air outlet 24 by way of a passage 64 containing a 'spring-pressed valve 68, Fig. 2. The water falling from the baffle collects in a float chamber '12 from which it is ejected, as the float 90 rises, by the raising of a valve 42, the stem 44 of which is connected to a diaphragm 46 secured between the upper and lower parts of the trap casing. A pressure drop on the top of the diaphragm is produced by flow of air as the valve 68 opens, the space above the diaphragm being connected to outlet 24 by passage 72 whilst the space below the diaphragm is subject to the pressure of incoming air. These pressures are normally neutralized by a valve passage 98 in the diaphragm so that the water-ejection valve is kept closed. An upward extension 88 on the float 90 engages a resilient disc valve 78 on a ring 80 which can slide on the extension 88. When the float rises, the disc 78 closes passage 98 in the diaphragm and the differential pressure opens the ejection valve 42. The float 90 then falls and. after an interval due to lost motion, the valve disc 78 is drawn away from passage 98 to allow spring 52 to close the ejection valve 42. In the modification shown in Figs. 5 and 7, the float control of the ejection valve 150 is dispensed with. This valve is controlled. as before, by a differential pressure on the top and bottom of a diaphragm 152 caused by the flow of air through the trap. Air entering at 114 passes through a venturi nozzle 128 leading to a convex surface 124 which disperses the entrained water that passes downwardly to the lower part of -the casing through ports 134, the air passing upwardly through ports 132 to leave through an outlet 118 after passing a gauze partition 136 serving to reduce turbulence. Leading from the air inlet to the water space at the bottom of the trap is a passage 174 and fine bore tube 178, the passage connecting by opening 172 with the space above the diaphragm. The space below the diaphragm leads to the air space by passage 170 so that the pressure on both sides of the diaphragm is normally equalized. As the water collects, the tube 178 becomes plugged with water and the consequent differential pressure on the diaphragm causes the waterejection valve 150 to open.

Abstract: 197,375. Ellis, C. P. Feb. 7, 1922. Catches yielding to pull and pressure. - Sliding doors are held in an adjusted position by means of a pivoted spring-pressed catch member on the door or frame for engagement with wide notches on the frame or door respectively, the catch being arranged to yield when pressure is applied to the door in either direction. As applied to the front edge of a slidable door, the catch comprises a member 1 pivoted at 1<a> and with right-angled adjacent edges on an extension piece adapted to be engaged by a coiled spring 2. Movement of the door to the right causes the catch to rock on its pivot by engagement with the walls of the notch 4<a>, the pivot pin 1<a> being depressed against the action of the spring during this movement. The spring restores the catch into a door-holding position when the door stops with one of the notches above the catch. A similar movement occurs when the movement of the door is reversed, a slot 3<a> housing the catch during the trailing movement. The catch may be rendered inoperative by forming it with an additional flat surface 1<h> for engagement with the plate 2<a> above the spring 2.

Title: Improvements in the refining of cellulose esters
IPC: C08B3/28
Filed: 1947-02-06
Abstract: The colour and clarity of a cellulose ester of an organic acid are improved by fractionally precipitating the ester from solution by means of a normally liquid aliphatic hydrocarbon which is miscible with the solvent of the cellulose ester solution. Alternatively, after a first fraction of the cellulose ester has been precipitated by means of the aliphatic hydrocarbon and separated from the supernatant solution, the greater part of the aliphatic hydrocarbon contained in the solution is removed by evaporation and cellulose ester is precipitated from the solution in a fibrous or flake form by means of water.  The process enables cellulose esters of good stability and strength to be freed from cellulose ester fractions which are of lower molecular weight, stability and strength.  Such refined cellulose esters are suitable for making films, foils, and moulded articles. Preferably, the cellulose ester is divided into three or more fractions by the fractional precipitation, and the middle fraction or fractions are segregated from the first and last fractions. The first fraction contains the major portion of the colour- and haze-producing constituents and the last fraction generally contains the major portion of the low molecular weight cellulose ester of poor stability.  Two precipitated fractions may be obtained leaving a third fraction in solution, and the second fraction may be segregated from the first and third fractions. The hydrocarbon may be pentane, hexane, or heptane, or a mixture of these hydrocarbons, e.g. petroleum ether.  The cellulose ester treated may be cellulose acetate, propionate, or butyrate.  A solution containing 2-10 per cent of the cellulose ester in acetone may be used.  The fractionation may be carried out at 15-30 DEG  C.

Abstract: 799,551. Extracting metals; iron manufacture. TEXACO DEVELOPMENT CORPORATION. Feb. 6, 1956, No. 3608/56. Classes 72 and 82(1) In a process for reducing metal oxide to metal in which a down-flowing bed of oxide is met by an up-flow of carbon monoxide and hydrogen whilst part of the resulting gas mixture is withdrawn at an intermediate point (21) in the bed and air is admitted to the bed above that intermediate point (at 18) for combustion of the remaining monoxide and hydrogen, nitrogen is also introduced to the bed above said intermediate point (at 24), and preferably below the air admission point, to ensure the temperature of the upper portion of the bed being below the.sintering temperature of the oxide. The process is said to be applicable to the production of Ni, Cr, V, Ti, and especially iron, a "sponge" metal being produced. The withdrawn gas mixture may be treated (at 22 and/or 14) to remove CO 2  and water vapour and the residual CO and hydrogen reintroduced into the lower part of the bed. As described for producing iron, oxide ore is admitted into furnace 12 at 16, preheated CO-hydrogen mixture at 11, air at 18, and nitrogen at 24. An air fractionator 5 supplies the nitrogen and also oxygen which is led along line 6 to a gas generator 7. There the oxygen pre-heated to 300‹F. is mixed with natural gas (or similar fuel) led in at 8 and which has been pre-heated to 1000‹F., the resulting CO- hydrogen mixture being treated if necessary at 13 for removal of sulphur and at 14 for removal of steam and CO 2  and led along line 11. CO 2  from the line 21 and separator 14, may also be led via 9 and 15 to the generator 7. Iron sulphide from separator 13 may be added to the ore at 16. The CO-H mixture should contain more than one and preferably two or three volumes of CO per volume of H 2 , and it is pre-heated to enter the furnace at 1750‹F. The gas mixture withdrawn at 21 is at about 1500‹F., whilst in the upper zone of the furnace the temperature of the ore is maintained at between 1400 and 2000‹F. Iron sponge is discharged at 17.

Title: Process for the production of gases rich in hydrogen
Inventor: DENT FREDERICK JAMES
IPC: C10G1/00
Filed: 1957-02-01
Abstract: A gas containing hydrogen is produced by reacting a carbonizable carbonaceous material, e.g. coal or a hydrocarbon-containing oil, with hydrogen or a gas containing hydrogen under a pressure of at least 10 atmospheres and at a temperature of at least 600 DEG  C. to produce a hydrocarbon-containing gas which is reacted with steam under a pressure of at least 10 atmospheres and at a temperature of at least 700 DEG  C. in the presence of a catalyst to give a gas containing hydrogen and carbon monoxide, the catalyst being arranged in a zone and heated by heat exchange through one or more heat conducting walls by combustion of a fuel with oxygen or an oxygen-containing gas under a pressure which is not more than 10 atmospheres and preferably not more than 5 atmospheres different from the pressure within the catalyst zone.  A suitable process for producing the hydrocarbon-containing gas is described in Specification 830,960 [Group XII].  The conversion of the hydrocarbon gas with steam may be carried out with the catalyst in tubes arranged within a combustion zone or the catalyst may be in a vessel containing tubes through which combustion gases are circulated and the catalyst may be maintained in a fluidized state.  Some of the heat required for the reaction with steam may be supplied by partial combustion of the hydrocarbon containing gases by adding air and the heating by partial combustion and the heating by combustion gases may be carried out in separate zones. The carbon monoxide in the gas produced may be reacted with steam in the presence of a catalyst to form hydrogen and carbon dioxide and the carbon dioxide removed by scrubbing with a hot solution of potassium carbonate.  The catalyst employed in the reaction between the hydrocarbon containing gas and steam may be a reduced nickel oxide supported on alumina and the catalyst for the reaction of carbon monoxide with steam may be iron oxide.
