Title: Apparatus for the catalytic gas reactions in liquid media
IPC: B01J19/00
Filed: 1955-01-20
Abstract: <PICT:0787123/III/1> Apparatus for carrying out gas reactions in the presence of liquid or solid catalysts dissolved or suspended in a liquid medium, through which the gaseous reactants bubble upwardly, comprises a vertical reactor which has a diameter or width not less than 30 centimetres and a length not less than 1.5 metres and which is divided into a number of vertical shafts open at both ends and having a width of at least 5 centimetres and a length of from 10-200 times the width; the lower ends of the shafts are at a distance above the gas inlet which is not substantially less than the width of the reactor, and in use the liquid level is within the shafts.  As shown, the cylindrical reactor 21 is divided into shafts 27 of hexagonal cross-section.  Gaseous reactants are introduced through nozzle 23 and the tail gas leaves at 26. Baffles 29 prevent the entry of gas into the space between the shafts and the wall of the reactor.  A regulator 28 controls the amount of liquid in the reactor by operating supply and discharge valves.  Liquid free from catalyst and containing high boiling reaction products may be withdrawn at 37. Catalyst suspension may be supplied or removed through tube 40.  The gas nozzle 23 is rinsed by liquid introduced at 25; various nozzle shapes are illustrated in Fig. 14 (not shown).  Heat exchange tubes 30 are provided for controlling the temperature of the reaction. Alternatively, the shafts may be of circular cross-section and the heat exchange tubes may be outside, or both inside and outside, the shafts.  The gas may be introduced evenly into the reactor through a series of jets directed downwardly towards the bottom of the vessel. Heat may be supplied to endothermic reactions by condensing steam in the tubes 30 or may be dissipated from exothermic reactions by vaporizing water in the tubes.  The apparatus is suitable for the hydrogenation of oxides of carbon under pressure to form hydrocarbons or oxygen-containing organic compounds.  For this purpose the cooling tubes may be modified so that the temperature in the reactor increases in the direction of gas flow.  For example, the cooling surfaces may be lined or the diameter or number of the cooling tubes may be reduced towards the top of the vessel.  Arrangements are illustrated in Figs. 15 and 16 (not shown) for creating a vapour cushion of adjustable length between the reaction medium and the cooling tubes.  Specification 786,888 is referred to.

Abstract: 210,456. Akt.-Ges. Brown, Boverie, et Cie. Jan. 29, 1923, [Convention date]. Motor power plant; transmission mechanism ; bearings ; balancing end-thrust.-In a compound turbine using steam at very high initial pressure and superheat, the high-pressure stage turbines are arranged to have small individual heat-drops as described in Specification 196,913, and their rotors are mounted in an overhung manner on pinion shafts which are disposed symmetrically around the main gear-wheel on the shaft of the low-pressure stage turbine or on the shaft of a dynamo. When two high-pressure stages are used they are disposed diametrically opposite one another in a horizontal plane. Fig. 2 shows two high-pressure stages a<1>, a<4> in series driving a main overhung wheel i. The casings are secured by flanges to the gear box and centering wedges or keys arranged crosswise are employed to locate the casings and permit expansion. The casings may be divided longitudinally in a plane inclined at 45‹ to the horizontal to facilitate access to the flange bolts. Four high-pressure stages may be disposed in pairs at opposite ends of a dynamo or low-pressure stage turbine. The axial pressure of the single-helical gears may be balanced by the end thrust of the steam-pressure on the shattless ends of the turbine rotors and the angle of the teeth may be chosen for this purpose. Fig. 4 shows a construction with the pinion bearings c, d and the labyrinth stuffing box s mounted in a common casting which is supported in bores u in the gear-box. Water is admitted to a groove q for cooling the shaft and the latter is equipped with oil and water deflecting rings r. Steam leaking through the gland s passes away at w and a passage z extracts any steam leading into the joint y.

Title: Improvements in or relating to Surface Finishing.
Inventor: SMITH ERIC FRANCIS
IPC: B24B31/06
Filed: 1967-01-18
Abstract: 1,158,303. Vibratory finishing. FOX CHEMICAL-ENG. WORKS Ltd. 11 March, 1968 [18 Jan., 1967], No. 2590/67. Heading B3D. The invention provides a process for finishing workpieces by means of a mass of finisher in a tub, in which the tub is vibrated about an axis therethrough so that the workpieces and the mass of finisher are caused to orbit about the axis and the finished workpieces are separated from the mass of finisher by the introduction into the orbiting mass of an extraction member which extends upward from its leading edge and which is perforated to allow the finisher to pass through in its orbital motion under the impulsion of the kinetic energy imparted to it by the vibration of the tub while the workpieces are deflected out of the mass of finisher by the member and are removed from the tub. The kinetic energy of the orbiting mass of finisher and workpieces may be altered by the introduction of a lubricant, e.g. water, during the separation so as to lower the velocity of the orbiting mass and hence the rate of extraction. An open top tub 1 is mounted to vibrate about an axis coinciding with an axle 2, the latter being connected to a vibratory mechanism. An extraction member 4 has spaced curved bars 5 and a perforated guide plate 6, the member being movable about a pivot from an inoperative position to the operative position shown. A tray 8 comprises spaced inclined bars 9 and side bars 10 depending from the member 4 by rods 11. The tray directs workpieces away from the axial area to ensure separation; it may be omitted in small scale apparatus. On the tub is mounted a pipe 12 having apertures 13 and a top 14. Liquid outlets 15 are provided in the tub.
