Filed: 1944-12-21
Abstract: 600,257. Making electron discharge devices. HOLMAN, H. E. Dec. 21, 1944, No. 25829. [Classes 83 (ii) and 83 (iv)]  Soldering.-Grids for electron discharge devices &c. are formed from a number of spaced flat metal strips of a hard refractory material which are tensioned and secured across the aperture in a supporting structure while under tension. Two discs of equal diameter having interposed two semicircular metal plates are welded &c. together to form a structure having a central aperture with a channel 13 formed by the semicircular plates at right angles to the axis of the aperture. The strips 14, 15, 16, 17, 18, Fig. 3, are drawn through this channel, strips 15, 17 being bent to compress and space the strips. Each strip is provided with a coating of gold, preferably by electrolytic deposition and when in position in the channel the structure is heated causing the gold to fuse to it and the strips. In a modilication, the strips are not bent, but are anchored to a support at one end and after drawing through the channel the free ends are attached to springs to tension the strips. Separating pieces, also gold plated, are placed between the strips and the structure heated to fuse the separators and strips to it. Heating of the strips is preferably carried out in a non-oxidizing atmosphere which may comprise a glass cylinder 30, Fig. 5, into which project hollow copper &c. electrodes 31, 32. The cylinder is closed at each end by asbestos washers 35, 36 and plates 33, 34 which can be firmly clamped to the cylinder to make it gas-tight. Carbon tips 37, 38 are affixed to the ends of the electrodes and are shaped to conform to the work being heated. Electrode 31 is movable axially and provided with a spring 39. to compress it on to the work. The hollow electrodes are provided with ports and gas is supplied to electrode 31 being exhausted through 32 and a conduit 41 to a suitable bubble indicating device 42. The interior of electrode 32 also contains a thermocouple 43 so that the temperature can be obtained by means of an instrument 45 and controlled current may be supplied by a stepdown transformer 40 or other suitable means and the strips may be plated with other metals such as silver or copper.

Filed: 1928-09-10
Abstract: 322,752. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 10, 1928. Cork composition.-Artificial cork masses are made by incorporating disintegrated cork or an equivalent material with less than 30 per cent of its weight of an unhardened resinous condensation product of urea, or of a derivative of urea, and formaldehyde or with a mixture of such condensation products, and moulding under pressure at ordinary or elevated temperatures. Softening or plasticizing agents, for instance polyhydric alcohols, sugars, or esters or ethers thereof, and acids or acid yielding substances adapted to accelerate the hardening such as formic acid, potassium bisulphate, magnesium chloride, formamide and formic acid esters may be added to the composition and also organic binding agents such as natural, or artificial resins, for instance gum acaroids or phenolformaldehyde resins, gelatin, dextrin, glue and rubber latex. In an example, 100 kilograms of cork meal are mixed with 20 kilograms of a 60 per cent aqueous solution of a condensation product of urea and formaldehyde, formed by condensing urea and formaldehyde in the presence of an acid condensing agent such as sodium tetroxalate and 1 kilogram of glycerol and 0.5 kilogram of formamide are added. The mass is moulded at about 100‹ to 140 C. under a pressure of about 100 to 200 atmospheres. In another example, urea nitrate is used as the condensing agent.

Title: Improvements in or relating to the production of alkali cellulose particularly useful for making cellulose esters or ethers
IPC: C08B1/08
Filed: 1935-09-19
Abstract: A process for the production of an alkali cellulose which is particularly suitable for the manufacture of esters or ethers comprises treating a cellulosic material containing esterifiable hydroxyl groups with metallic sodium in the presence of water and of an excess of liquid ammonia, the proportion of metallic sodium used being at least equivalent to the esterifiable hydroxyl groups of the cellulosic material, and at least sufficient to afford an alkali cellulose product which is substantially dry to the touch after removal of the ammonia by evaporation.  The water present during the reaction may be added as such or introduced as hygroscopic moisture with the cellulosic material or ammonia.  The cellulosic material may be an alkali cellulose prepared in the usual manner by treatment with aqueous caustic alkali, wood pulp, cotton linters, hydrocellulose, oxycellulose, or low substituted glycol cellulose, cellulose acetate, cellulose propionate, cellulose butyrate, or cellulose glycollic acid.  In an example 81 parts of cellulose were steeped for one hour at 20 DEG  C. in 40 per cent caustic soda, pressed to 374 parts, and shredded, 16,2 parts of this alkali cellulose were mixed with 100 parts of liquid ammonia containing 2,23 parts of metallic sodium. When the blue colour of the sodium had disappeared the majority of the ammonia was driven off, 100 parts of toluene added and the mixture heated to 100 DEG  C. to drive off residual ammonia.  The product had a molecular ratio of water to sodium hydroxide to cellulose of 8 : 11 : 1.  It was especially suitable for making esters, e.g. the toluene suspension of alkali cellulose was cooled to 20 DEG  C., 5.2 parts of p-toluene sulphonyl chloride added, the temperature being kept below 30 DEG  C. at first and then raised to 100 DEG  C. for 5 hours.  The toluene was then poured off and the solid p-toluene sulphonate washed with ether, followed by water.  The product contained 1,7 ester groups per C6H10O5.  Its acetone solution gave a film or filament of good strength.  In a second example 1000 parts of liquid ammonia, 135 parts of water and 178 parts of metallic sodium were added to 400 parts of cellulose.  On disappearance of the blue colour of the sodium, ammonia was evaporated off, 10,000 parts of toluene added and the mixture heated to remove residual ammonia. In a third example no water was added, and 2000 parts of liquid ammonia and 26 parts of metallic sodium were added to 40 parts of cellulose.  Subsequent procedure was as in the other examples. Specification 187,639, [Class 2 (ii)], is referred to.

Title: Improvements in independently fired tubulous vapour heaters
Inventor: SCOTT DAVID HOWARD
IPC: F22G1/16
Filed: 1960-07-28
Abstract: 911,870. Steam superheaters. BABCOCK & WILCOX Ltd. July 26, 1961 [July 28, 1960], No. 26263/60. Class 123 (3). In an independently-fired superheater which receives steam from an intermittent source such as the waste heat boiler of a Bessemer converter, overheating of tubes lining the superheater furnace is prevented by two control means, the first maintaining a constant final steam temperature whilst the second is responsive to steam temperature at the outlet of the furnace tubes and exerts an overriding control to limit this temperature to a safe value when the steam supply falls. As shown, the superheater has a tube-lined furnace 2 fired by blast furnace or coke-oven gas burners 26, the gases flowing from the furnace through a lateral outlet into a horizontal pass 20 locating a final convection superheater 60. The gases leave the pass 20 through an opening in the floor thereof and flow upwardly in a pass containing a primary convection superheater 34 to discharge through a duct 64 to an air heater 66 whence they pass through an induced draught fan 70 to a stack 72. Steam flows from an inlet header 28 through the superheater 34 and then the furnace lining tubes to a header 54 whence it passes through the final superheater 60 to the outlet header 62. A temperaturesensitive element in the header 62 regulates the supply of gas to the burners 26 by adjusting the setting of a damper 86, a combustion-air control maintaining a suitable ratio of air flow to gas flow, to maintain the final steam temperature constant. A second temperaturesensitive element in the header 54 regulates the supply of excess air to the burners by adjusting the setting of a damper 80 to ensure by limiting the temperature of the steam leaving the furnace tubes that a safe value of the temperature of the tube metal is maintained at all times. In a modification, the second control means regulates the rate at which cooled flue gases are recirculated to the furnace chamber.

Title: Production of carbon monoxide and hydrogen
Inventor: NONNEMACHER HELMUT
IPC: C01B3/38
Filed: 1961-07-21
Abstract: A process for the flameless catalytic reaction of liquid sulphur-containing hydrocarbons, especially those containing non-vaporizable constituents, with amounts of oxygen insufficient for complete combustion, to form carbon monoxide and hydrogen, comprises spraying the initial material at a temperature of 800 DEG  to 1200 DEG C.; preferably 900 DEG  to 1100 DEG C., into a fluidized layer of a nickel catalyst and/or a sulphidic catalyst into which steam and/or CO2 necessary for the reaction is introduced as fluidization agent, and the gas rich in CO and H2 formed is reacted, for conversion of the hydrocarbons and carbon black contained therein, in a further fluidized layer in the presence of a nickel catalyst at a temperature at least 20 DEG C, and preferably at least 50 DEG C., below that of the first stage.  Both the initial material and the fluidization agent may be preheated, e.g. to 300 DEG  to 500 DEG C. and to 130 DEG to 600 DEG C. respectively.  The oxygen and the steam and/or CO2 may be introduced separately, and 25% to 30% of the steam and/or CO2 may be introduced at the second stage.  Pressures may be from normal to 50 atmospheres.  In an example, a crude oil consisting of 85,6%C, 12,4%H, 2,6%S (per centages by weight) and a net calorific value of 9860 kg. cal. per kg. was sprayed into a fluidized catalyst of 0,2 mm. mean grain size containing 15% Ni and 10% Zr O2 (by weight) with oxygen and steam (preheated to 130 DEG C.) for gasification and fluidization at 1000 DEG C.  The gas produced contained H2S, CH4, tar, atomized oil and carbon black, and was led into a second fluidized bed of the same catalyst and reacted with steam and CO2 at 930 DEG C. to form a gas comprising:-53,7% H2, 37,0% CO, 8,9% CO2, 0,1% CH4, 0,3% H2S.

Title: Improvements in automatic stoking devices for central heating boilers
IPC: F23N1/00
Filed: 1936-09-30
Abstract: 469,293. Controlling fuel supply; stoking. VULCANSONS, Ltd., and FAWKES, W. H. Sept. 30, 1936, No. 26543. [Class 51 (i)] [Also in Group XVIII] Means are provided which, in operation, feed solid fuel in regular quantities at definite intervals on to the furnace grate and also shake the bars or other agitating devices separate from the grate to loosen the fuel bed. A supply of pressure water entering at 19 drives the pistons 14, 15 one way or the other according to whether the valve 22 is open or not. When valve 22, is open, water under pressure passes along 24 to press on the right hand face of 15 and since 15 is greater than 14 to which it is joined by a rack-bar 13, 14 and 15 move to the left together, causing rotation of pinions 12 and 58. Rotation of 12 rotates the fuel box 11 while gearing 58, 59, 60 and connecting rods 63, 64 cause vibration or oscillation of the shaft 4 of the grate. If 64 is prolonged at 68 and provided with teeth 68a co-operating as shown with a spring- pressed detent 69, shaking of the bars is thoroughly assured. Closing of the valve 22 causes the pistons to move back again, shaking the bars afresh and bringing the box 11 back to its original position. The timing of the operation is governed by the flow of water from a reservoir 30 into a tank 44 wherein a float 45 can be made to rise and to snap a roller 51 on bar. 48 past a stop 52 on a spring- urged and pivoted rod 53. The snapping up of the bar 48 carrying roller 51 causes opening of the valve 22 through engagement of the tail-piece 48a with the rod 57. After valve 22 opens water passing along the passage 24 and through an ejector 25 causes the tank to empty. Flow from or to the tank can be controlled by adjustment of a stop 70. The flow from the reservoir 30 can be adjusted by means of the device illustrated in Figs. 3 and 4 (not shown), and, in part, in Fig. 2. The water runs out through a pipe 33 to a plug in the casing 29. The plug has passages formed in it so that no water can pass through in one position, in another there is restricted passage and in the third there is free transit. A thermostatic element 72 can influence the setting of a needle element 42 further to control the water supply from the reservoir.
