Title: Destructive hydrogenation of petroleum oils
IPC: C10G47/00
Filed: 1946-06-24
Abstract: Hydrocarbon oils of the type of heavy naphthas, kerosene and gas oils, are subjected to a two-stage destructive hydrogenation for the production of gasoline; in the first stage to catalytic hydrogenation in the presence of a sulphur-resistant catalyst comprising oxides or sulphides of metals of the Sixth Group of the Periodic System, either alone or in admixture with oxides or sulphides of Group Eight and at temperatures within the range of 600 DEG  to 900 DEG  F., and under pressures within the range of 1000 to 3500 lbs. per sq. in., and, in the second stage, after removal of the gasoline range, to catalytic hydrogenation in the presence of a sulphur-sensitive catalyst containing metallic iron, nickel or cobalt at a lower temperature, within the range of 500 DEG  to 800 DEG  F., and under a lower pressure, within the range of 500 to 1500 lbs. per sq. in.  The catalyst for the first stage may be (1) mixtures of molybdenum oxide, zinc oxide and magnesium oxide, (2) molybdenum sulphide, (3) tungsten sulphide supported on activated clay prepared by impregnating it with a solution of tungstic oxide in ammonium sulphide, (4) iron sulphide supported on activated bentonitic clay.  The catalyst for the second stage may comprise metallic nickel, cobalt or iron deposited upon highly active catalysts for cracking processes such as "Super-filtrol" (Registered Trade Mark), aluminium silicate, silica - alumina, silica - magnesia and silica - alumina-magnesia gels, or acid-treated clays of the bentonitic and montmorillonitic type. The carrier may be first treated with fluorine, hydrofluoric acid, fluosilicic acid or other fluorine-containing compounds before the deposition of the metal which may form between 1 and 15 per cent by weight of the total catalyst.  A catalyst comprising about 7 per cent metallic nickel on hydrofluoric acid-treated "Superfiltrol" is prepared by impregnating the treated carrier with nickel nitrate, extruding, drying, heating to 550 DEG  to 750 DEG  C. to convert the nitrate to oxide, and reducing to metallic nickel by heating in an atmosphere of hydrogen.  The hydrogenation of Quiriquire kerosene plus 0.3 per cent carbon disulphide is described with reference to a diagrammatic drawing of the apparatus (not shown).  Specification 596,434 is referred to.  The Specification as open to inspection under Sect. 91 comprises also the use in the second stage of a sulphur-resistant catalyst of the same type as that used in the first stage.  This subject-matter does not appear in the Specification as accepted.

Abstract: 220,655. Synthetic Ammonia & Nitrates, Ltd., (Assignees of Kniskern, W. H.). Aug. 16, 1923, [Convention date]. Separating gaseous mixtures by liquefaction.- Gaseous synthetic ammonia is recovered from a gaseous mixture by subjecting the mixture, in stages, to a cooling action obtained by evaporating portions of the same volatile liquid cooling agent at successively lower pressures. The vapours evolved may be recompressed and cooled for further use. The gas passes successively through coils 11, 13 in vessels A, B, and the ammonia liquefied in the coils is removed by separators 14, 14<a>, while the residual gas passes though a pipe 16 to another part of the synthetic plant. Liquid ammonia or other volatile fluid is expanded into the vessels A, B, through valves C, C<1> at pressures of, say, 25 and 15 lb. absolute, these pressures being maintained by the suction of compressors E<1>, E<2>, which compress the evaporated gas to say 155 lb. and force it through a water cooled coil D and a receiver R to the pipes 19, 20 leading to the expansion valves. In a modification, the whole of the liquid is expanded through a valve into the vessel A, from which the vapour is withdrawn by the compressor as before, while the liquid portion is further expanded into the vessel B; an additional cooler is interposed between the receiver R and the valve C. In a further modification, the compressors E<1>, E<2> deliver the gas to a second stage compressor through a water cooler and a second cooler in which the ammonia from the second stage compressor is liquefied by expansion to the first stage pressure before passing to the vessels A, B, and after passing through two water coolers. and an intermediate receiver.

Title: Improvements in or relating to apparatus for splicing cinematograph film
IPC: G03D15/04
Filed: 1944-10-11
Abstract: 589,243. Film - splicing machines. HALL, B. H. Oct. 11, 1944, No. 19572. [Class 98 (ii)] The machine comprises a base, having two horizontally spaced platforms, one of which is provided with film-registering pins, a carrier, bearing film-registering pins, and slidably mounted over the second platform for movement towards and away from the space between the platforms, means for clamping the film on the carrier and the first platform while allowing the film to be moved with the carrier, and a cutter arm pivoted to the base so that it may swing down into operative position between the platforms where it co-operates with the adjacent edges of the platforms to shear the film. A scraper bar may be slidably mounted on the cutter arm to remove the picture layer from one film end after cutting, and a pressure member may be provided on the base to ensure a good joint. As shown, a space 3, of width equal to a single frame or film, separates platforms 2 on the base 1 of the machine. A carrier 4, provided with film registering pins 8, has eyes 5 embracing a rod 6 horizontally. mounted in lugs 7 on the base, so that it is movable over the right-hand platform through a distance of two frames towards or away from the space 3. The film is held on the carrier by a plate 13, hingedly mounted at 14 between the eyes 5 on the rod 6 and having lips 12 adapted to clip over the front edge of the carrier 4. A similar plate 9 pivoted on a rod 10 mounted in lugs 11 on the base serves to retain the film on the left-hand platform 2. Both plates 9, 13 have holes 15 to receive the pins 8. An arm 17, fitted with a flat spring- steel blade 18, which can pass as a press-fit through the space 3 to shear away a film frame, is pivotally mounted in a bracket 16 on the base, while a scraper bar 19, with knob 29 is carried on the arm and has pin-and-slot slidable connection therewith. Also pivoted on the bracket 16 is a film pressure arm 22, the pivot stud 23 thereof passing through a slot 24 so that the arm may be moved towards or away from the space 3. When the arm is moved to operative position, a cam 25 thereon coacts with a pin 26 depressible against a spring 27 fast on the base to apply and maintain pressure on the film. In use, e.g. to remove one picture frame from the film, the film perforations are engaged with the pins 8 on the platform and on the carrier, which is in its extreme righthand position, and the plates 9, 13 clamped down. The arm 17 is depressed causing the film space to be cut out by blade 18, and the picture layer on the left-hand film piece is removed by the scraper 19. After raising the arm 17 adhesive is applied and the carrier 4 is moved to its left-hand position so that the cut ends of the film overlap. The pressure arm 22 is moved into operative position to cause the pivotally suspended foot 28 to press the ends together until the joint is secure.
