Title: Improvements relating to the catalytic desulphurisation of petroleum hydrocarbons
IPC: C10G45/24
Filed: 1949-05-23
Abstract: Petroleum hydrocarbons are desulphurized by passage, without addition of hydrogen, over a catalyst which is effective for the dehydrogenation of naphthenes to aromatics and the hydrogenation of organic sulphur compounds and which is not poisoned by sulphur compounds, under conditions of elevated temperature and pressure such that the feedstock remains substantially in the liquid phase and sufficient hydrogen is produced by dehydrogenation of naphthenes contained in the feedstock to convert organically combined sulphur in the feedstock into hydrogen sulphide. Preferably the catalyst consists of a mixture of cobalt and molybdenum oxides, or a chemical compound of cobalt, molybdenum and oxygen, or a mixture of one or both oxides with such a compound, either alone or incorporated with a support.  The temperature may be 700 DEG -800 DEG F and the pressure may be 500-1000 lb./sq. in. or more, depending on the boiling point of the feedstock.  The process is preferably carried out in a downflow reactor.  The examples describe the dehydrogenation-desulphurization of a gas oil of A.S.T.M. boiling range 256 DEG -356 DEG C, two kerosines of boiling range 184 DEG -264 DEG C, blends of naphtha (145.5 DEG -212 DEG C), kerosine (184 DEG -264 DEG C), and an SO2 extract from crude oil (160 DEG -291 DEG C), a wax distillate (260 DEG -582 DEG C), a catalytically cracked gasoline (100 DEG -230 DEG C) and an Iranian crude fraction from I.B.P. up to 350 DEG C. Specifications 654,152, 663,038, 669,536, 669,552 and 669,553 are referred to.  The Provisional Specification refers also to a modification of the process in which the necessary hydrogen in the desulphurization zone is obtained by dissolving a small amount of extraneous hydrogen in the feed.

Patent GB-593564-A (GB)
Title: Improvements in or relating to the production of protein filaments
IPC: C08L89/00
Filed: 1945-06-07
Abstract: Artificial filaments obtained by extruding a solution of a vegetable globulin or casein into an acidified saline coagulating bath are given an increase in strength by stretching the coagulated unhardened filaments in presence of a saline solution having no swelling effect on them and at a temperature not exceeding 40 DEG  C., and then subjecting them in the stretched condition to the action of a hot saline solution at a temperature above 40 DEG  C., which also has no swelling effect on the stretched filaments, until they have substantially lost their contractility.  The freshly coagulated filaments may be stretched in presence of the acidified saline solution of the coagulating bath and, if desired, they may be stretched in air in presence of the liquid that adheres to them when they leave the coagulating or other suitable saline bath.  The hot saline solution may, if desired, contain a salt the same as that in the solution in presence of which they were stretched or a salt that is present in a subsequent hardening solution, and it may include ingredients which assist the hardening of the filament.  The process of stretching and liquid treatment may be repeated as many times as may be practicable.  In an example, a matured alkaline solution of peanut globulin is spun into an aqueous coagulating bath at 28 DEG C. containing sulphuric acid and sodium sulphate.  The filaments so produced are stretched as they emerge from the bath and are wound upon a swift, whereupon they are sprayed with a solution of sodium sulphate at 45 DEG  C.

Filed: 1954-05-17
Abstract: 773,506. Cathode ray tubes. SOC. GENERALE D'ELECTRONIQUE. May 17, 1954 [May 19, 1953], No. 14470/54. Class 39(1). A television light modulating screen is manufactured by evaporating three or more substances in succession on to a support 3, the first and second substances being evaporated through a masking grid 4 to form strips 6, 8 respectively which do not entirely overlap and the third substance being evaporated (with no masking grid present) to form a continuous layer, and finally the assembly is heated to remove the second substance 8 by evaporation. The second substance may be cadmium, mercuric iodide or ferric chloride, and the third substance may be beryllium. The first evaporation from small crucible 5 gives strips 6, and the second evaporation at a lower temperature, e.g. 450‹C., from large crucible 7 gives strips 8 overlapping strips 6 slightly at the edges. After this the masking grid 4 is removed and the third substance or substances axe evaporated from a further crucible (not shown) ; one of these layers may form a reflector. In an alternative method, crucibles 5 and 7 are placed in succession in the same position but the grid 4 is moved laterally by a distance equal to half its pitch between the first and second evaporations. In another alternative the second evaporation is carried out through a grid whose wires extend at right angles to the direction of the wires of the first grid, in which case strips 8 extend at right angles to strips 6. In another alternative a further layer is added to the third layer by deposition, through grid wires at right angles to the wires used for the first two evaporation steps, thus giving a layer of variable thickness.
