Title: Process for the production of carbon black
Inventor: LUDLUM ROBERT LEWIS
IPC: C09C1/48
Filed: 1951-03-06
Abstract: <PICT:0695492/III/1> Carbon black is produced by burning a liquid, liquefiable, or gaseous carbonaceous material with a limited quantity of air, cooling the combustion products by bringing them into contact with a finely divided inert solid matter which is cooled by a medium which does not contact the combustion products, and separating the carbon black.  Carbonaceous materials may be natural gas, methane, ethane, refinery gases, gasoline, gas oil, kerosine, heavy fuel oils, or petroleum residues or extracts, or carbolic oils, creosote, or anthracene oils from heavy coal tar. Inert solids may be, sand, alumina, magnesium oxide, iron ore, or carbon, or the spheroidal alumina or silica particles used in fluidized catalytic cracking of hydrocarbon oils, or wholly or in part oxides or carbines of Group VIII metals, e.g. iron, which promote decomposition of carbon monoxide in the combustion products to carbon and carbon dioxide to increase the carbon yield.  Hydrocarbon and air are fed to burner 1, and the partial combustion occurs in fire brick chamber 4.  The combustion products pass through pipe 8 to quench chamber 10 having a fluidized bed at say 250 DEG -400 DEG C of sand of average diameter 0.1-0.5 m/m, from which heat is extracted by water, steam, or oil, passing through coil 13, and is used for useful work elsewhere. The combustion products pass out through disengaging section 14 and cyclone 15 to filter box 19 where carbon black is removed on flannel cloths on supports 20, while remaining gases pass out at 21.  To assist in the cooling an empty vessel 24 may be provided and air may be injected at 23.  Alternative apparatus is described where the burner is situated immediately below the fluidized bed, Figs. 2, 4 (not shown), where a fixed bed of fireclay chips (2-10 m/m dia.) is situated below the fluidized bed, Fig. 3 (not shown), and where the inert solid of the fluidized bed is withdrawn for cooling, Fig. 5 (not shown).  Supplementary air or steam may assist fluidization and a cyclone may be used to separate carbon black.  Alternatively the inert solid may enter the base of a first vertical chamber with the combustion products and is carrie dup with the gases and separated therefrom at the top, when the inert solid is cooled while passing down through a second chamber, in which it may be fluidized, by direct or indirect contact with say water or oil, before return to the first chamber.

Title: Improvements in and relating to lifting jacks
IPC: B66F1/00
Filed: 1939-02-21
Abstract: 525,455. Lifting-jacks. JOHNSON, A. L. Feb. 21, 1939, No. 5791. [Class 78 (iii)] A lifting-jack of the kind having a ratchet lifting-action and screw lowering action, comprises a rotatable screw-threaded standard which does not move axially, a load-carrying member moved axiallv on the standard and raised step-by-step, and a sustaining nut engaging the threads on the standard and adapted to sustain the load in normal circumstances, but also giving a screw lowering action when the standard is rotated positively in the appropriate direction. In the form illustrated in Fig. 1, reciprocation of the lever 26 causes the spring- pressed pawl 28 to advance step-by-step on the quick threaded column 11 and so raise the sleeve 15 carrying the crutch member 17 which is fitted for example with a projection 20 for engaging the bumper of an automobile. On the downstroke of the lever the rising sleeve presses the ball bearing 37 against the under surface of the nut 33 and allows the latter to rotate freely and thus move axially on the screw. On the upstroke of the lever the surface of the casing engages the nut and prevents it rotating, thus causing it to sustain the loaded sleeve. To lower the load, the end 39, Fig. 6, of the handle 26 is inserted in the slot 38 in the top of the screw and the latter is rotated to lower the sleeve. In one modification, the column is fitted with buttress threads, and a divided nut is used which separates to allow the sleeve to pass upwards freely. Fig. 12 shows a further modification in which sustaining pawls 53 are pivoted on shafts 60 mounted in the sleeve and project through slots 62, their inner ends being forced by springs 63 into contact with the column. These pawls slip over the buttress threads as the sleeve moves upwards. In all forms the column has a ball-shaped lower end 12 which rests in a corresponding recess in the base-plate.

The mirror 14 is pivotably mounted and adjustable by verniers 20. The necessary requirement is that the ray path length between the lens should be constant and equal to the sum of their focal lengths, i.e. the lens system acts as a telescope, and the distance of real pivot 16 from lens 24 altered on the lens being focused. The beam is focused near the entrance aperture of, e.g. laser discharge tube 34 by focusing lens 24 and adjusting frame 28 carrying both lenses by rack and pinion 30, 32. The body 6 of the device is then adjusted about perpendicular axes 4, 5 on its base 2 via screws 7, 8 to centre the virtual pivot 26 on the entrance aperture of tube 34, after which the inclination of mirror 14 is adjusted whereby the output beam has its direction altered through the fixed point 26 until it aligns with the axis of the tube 34, shown tilted on the axis 36 of lens 24. The path of the beam may be a 'Z' as shown or 'L' or 'U' shaped. The device may be used to test for straightness or roundness of internally reflective tubing or, using a long focus output lens and a scale on the device, for measuring the distance to a remote point.

Title: An improved process for the destructive hydrogenation of coal, tars, mineral oils and the like
IPC: C10G1/08
Filed: 1929-01-05
Abstract: 328,992. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 5, 1929. Divided on 326,184. Hydrogenation, destructive.-In the destructive hydrogenation of carbonaceous materials in the liquid or pasty condition in the presence of catalysts in suspension, the difference in density between the initial material and the catalyst is so reduced that the latter remains in permanent suspension and does not accumulate in the lower parts of the reaction vessel. The density difference mav be reduced by additions to the initial material or by the use of a carrier such as charcoal, kieselguhr, or Florida earth for the catalyst. A part of the reaction liquid may be drawn off continuously or periodically for regeneration of the catalyst. Suitable catalysts are those immune to sulphur poisoning, such as are referred to in Specification 326,184. In an example, a brown coal tar fraction of density 0.82 is treated with hydrogen at 460‹ C. and 200 atmospheres in the presence of a suspended molybdenum catalyst of density 0.85. The catalyst is made by impregnating wood charcoal granules of 24 mm. diameter with ammonium molybdate solution and subjecting them to reducing treatment with hydrogen at an elevated pressure. In another example, a tar of density 0.96 is mixed with 20 per cent by weight of anthracene oil to bring the density to 1.1. The mixture is treated with hydrogen at 460‹ C. and 200 atmospheres in the presence of a catalyst prepared by impregnating pumice with ammonium molybdate and reducing it in a current of hydrogen. The density of the catalyst is 1.2.

Abstract: 450,027. Electric signalling systems. STANDARD TELEPHONES & CABLES, Ltd., Connaught House, Aldwych, London.- (Assignees of MatÚriel Telephonique Soc. Anon. ; 46, Quai de Boulogne, Boulogne-sur-Seine, France) Feb. 25, 1935, No. 6013. Convention date, May 24, 1934. [Class 40 (i)] [Sec also Group XL] In a direct reading radio direction finder employing a continuously rotating loop, the output current of the loop is commutated and supplied to the moving coil of an electromagnetic indicating device. Alternatively, the output may be supplied directly to the coil of the indicator, the magnetic field of which is com mutated. As shown. the outputs of a rotating frame aerial 1 and a vertical aerial 2 are combined in a detector amplifier 3 which supplies the slip-rings 6 of a commutator 8 rotated with the frame aerial. A coil 9 mounted in the field of a permanent magnet 11 is connected to brushes supported by the coil and rotatable on the commutator. When the instant of commutation corresponds to the reception of maximum signal strength currents of equal polarization flow in the circuit of the coil 9, but when this condition is not fulfilled unequal polarized currents flow in the coil 9 and the coil is driven into a new torque position, a pointer 13 then indicating the direction of the transmitting station. In a modification the output current of the amplifier 3 is supplied through the commutator to a polarized relay which supplies current in one or other direction to the coil 9 ; moreover the output current may be supplied directly to the coil 9 and the field magnet energized by current which is supplied over the commutator. Furthermore in another arrangement the field magnet may be excited electrically and the coil 9 replaced by a wound armature. In a further modification, the output-controlled relay operates a pair of electromagnetic clutches which engage one or other of two continuously driven rubber rollers with an indicating disc which controls the movable commutator brushes. In the event that the vertical aerial is dispensed with, the second position of equilibrium is eliminated by rotating the commutator at twice the speed of the frame aerial or providing a four-segmented commutator. The Specification as open to inspection under Sect. 91 describes a system wherein a potentiometric polyphase generator may be driven with the rotating frame aerial, the polyphase currents producing in an indicator a rotating field which co-operates with the field produced in a coil supplied from the aerial. That Specification also describes a system wherein the output currents of the aerial may be supplied to the deflecting electrodes of a cathode ray tube indicator which is rotated at the speed of the frame. Instead of rotating the tube. the ray may be subjected to a rotating field. This subject-matter does not appear in the Specification as accepted.
