Title: Process and apparatus for contacting a liquid with a gas
Inventor: EUWE GERRIT EVERT
IPC: B01F3/04
Filed: 1956-08-24
Abstract: XII <PICT:0858050/III/1><PICT:0858050/III/2> In a process for deodorising an oil with steam, the steam is injected upwardly into the lower portion of a horizontal stream of the oil along a length of the stream to cause the mixture of oil and steam in a longitudinal zone of the stream to rise to a position in which it moves to a second longitudinal zone of the stream spaced transversely from the other longitudinal zone and wherein the oil descends and returns to the first longitudinal zone so that the oil follows a helical path in the direction of flow of the stream.  The pro cess may be carried out under vacuum and the steam may be injected at a plurality of points at a pressure not less than twice the static pressure at the point of injection.  The ratio of the speed of local circulation to the speed of longitudinal movement of the stream of oil is preferably not less than 100:1 and may be 1000:1.  In the apparatus shown, the oil is passed through a series of concentric circular channels arranged on a tray with a central opening and connected so that the oil flows from the innermost channel to the outer most channel.  A number of such trays are arranged one above the other in a vertical column and oil from an outermost channel flows to the innermost channel of the next lower tray through a pipe 38.  Steam is fed into each channel from a pipe 28 and a hood is provided over the partitions which divide each channel into two transversely spaced zones.  The steam containing the odorous sub stances passes to a central duct 39 from which it is removed by an evacuating arrangement (not shown).  As shown in Fig. 7 a plate 21 cuts across all the channels and oil flow be tween the channels is by way of gaps 23 and 24 in the walls of the channel.

Title: Improvements in the manufacture and production of shaped articles of metallic oxides
IPC: B22F3/24
Filed: 1928-09-10
Abstract: 324,028. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 10, 1928. Electrodes comprising metallic oxides are obtained by subjecting to oxidation porous articles of metals or metal alloys, or of metals reinforced bv a more difficultly oxidizable metal in compact form which is not oxidized under the conditions imposed. According to the invention, as starting materials porous masses obtained by sintering metallic powders by heat with or without pressing and especially those obtained by sintering powders obtained by decomposition of metal carbonyls. are used. According to the Provisional Specification, porous articles of metal prepared in any manner, for instance by pressing metal powders. may be employed. When iron is the initial material, the reinforcement may consist of metal spangles, metal wool, wire nets, or perforated metal plates of copper, nickel, or a noble metal. Oxidation may be partial or complete, and according to the porosity of the initial material, the product may be porous or compact. Oxidation may be effected by air, oxygen, carbon dioxide, or steam, and may take place first at comparatively low temperatures, and then at higher temperatures which should not, however, reach the melting point of the metals or the oxides produced. Increased, normal, or reduced pressures may be used. In examples, a highly porous iron plate is first heated gradually to 400‹ C. in a stream of carbon dioxide, and then at 600‹ C. until oxidation is complete to obtain a porous plate of ferroso-ferric oxide; and a highly porous plate obtained by sintering together iron powder and nets of nickel wires at elevated temperature in a current of hydrogen is oxidized at 550‹ C. in a current of carbon dioxide to obtain a porous plate of ferroso-ferric oxide reinforced with nickel. Specification 311.141 is referred to.

Abstract: 648,509. Cathode-ray tubes. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A GAZ. Oct. 7, 1948, No. 26200. Convention date, Jan. 28. [Class 39 (i)] An electrode on which is formed an image of a television or like picture comprises a layer having a thin film of metal in contact with one face thereof and a mosaic of metallic particles deposited on the other face, there being not less than 30 particles in each elementary picture area of the electrode. On a film 2 of aluminium or aluminium-beryllium alloy is deposited a storage layer 1 of insulating or semi-conducting material such as magnesia. The image to be stored on the electrode reaches the film 2 in the direction indicated by the bank of arrows and the electron beam scans the electrode on its opposite face as indicated by the single arrow. On the storage layer 1 is deposited a fine microscopic mosaic 3 of metallic particles such as aggregated silver uniformly distributed over the surface so that each picture point contains from 30 to 300 particles. This masks the local differences in the secondary emission of the film 2. If the layer 3 is composed of silver or antimony particles subjected to photo-electric sensitization it can be used as a source of photoelectrons: The layer 1 may be replaced by a layer of fluorescent material on which has been deposited a substance which undergoes changes in conductivity under the influence of light. Alternatively the layer 1 may be a material of which the resistance varies directly under the impact of electrons which have traversed the film 2. The film 2 may be replaced by a thicker metallic sheet carrying a storage layer or mosaic which is struck on the same side by the image and by the scanning beam.
