Title: Improvements in and relating to the chilling of hot cracked gases
IPC: C10G9/00
Filed: 1959-02-26
Abstract: 912,367. Cooling gases by direct contact with cooling medium. FARBWERKE HOECHST A.G. Feb. 26, 1959 [Feb. 26, 1958], No. 6797/59. Class 64 (1). Hot gas at a temperature of at least 700 C., produced by cracking hydrocarbons, are chilled by contacting the gases with droplets of cooling liquid having a boiling-point such that the droplets are evaporated by the hot gases, which are thereby cooled. The chilling liquid may be petrol, but is preferably water under pressure at a temperature of 100 to 150 C. The hot gases are introduced through tube 2 into vessel 1, and water is sprayed in through nozzles 6. At the same time the walls of the vessel 1 are washed by a film of hydrocarbon oil, introduced through inlet 12 and annular slit 7, so as to keep the walls free from deposits of carbon and tar. The wash oil preferably has an inlet temperature of 150 to 250 C. In order to cool the lower part of tube 2, steam or hydrocarbon vapour is introduced into jacket 10, whence it passes through annular slit 4 to enter vessel 1 at high speed. The wash liquid and the chilled gases are brought into intimate contact at outlet 8, whereby the gases are further cooled and residual suspended particles are removed. The wash liquid is thereby heated up and lowboiling constituents are evaporated from it. The Specification refers to the production of ethylene and acetylene.

Title: A hydraulic pump having a swash plate with variable inclination
Inventor: LEDUC GERARD
IPC: F04B1/29
Filed: 1969-02-07
Abstract: 1,260,203. Reciprocating pumps. G. LEDUC. Feb.7, 1969 [Feb. 7, 1968], No.6866/69. Heading F1A. [Also in Division G3] In a hydraulic pump the inclination of the swashplate 9 pivoted to a support 8 and fast with the driving-shaft 7 is made variable by the action of a piston 12 which is supplied by outlet pressure fluid via a regulating valve 27 which has one face subjected to the delivery pressure and the other face to the combined action of a spring 24 bearing on the swash-plate 9 and an intermediate hydraulic pressure which is lower than the delivery pressure. The pressure reaches the interior of the piston 12 via a calibrated orifice 18 thus providing a back pressure on the valve member 27 in addition to the spring 24. A safety valve 36 is provided to limit the maximum value of the delivery pressure and comprises a valve member 37 which is subjected on one face to the outlet pressure and on the other to a spring 38. An annular chamber (40), Fig. 2 (not shown) surrounding the valve member 37 communicates via a non-return valve (42) with one of the bores 4 of the pump which thus provides a pulsatory delivery pressure to the annular chamber (40). When the delivery pressure exceeds a predetermined value the valve member 37 is lifted, subjecting the piston 12 to the pulsatory pressure delivered from the pump bore 4 so that the piston 12 advances in steps until the angle of the swash-plate is zero.

Abstract: 1,241,275. Cathode-ray tubes. ENGLISH ELECTRIC VALVE CO. Ltd. 16 Jan., 1970 [12 Feb., 1969], No. 7650/69. Heading H1D. In an image intensifier or an image orthicon or like pick-up tube, the transparent support for the photo-cathode is grooved to form patterns of a width of 2-50 microns, so that the photo-emissive layer formed over the support receives light which has passed directly through the support and also light which has been internally reflected at the grooves. The grooves may be parallel and symmetrical (Fig. 1) or asymmetrical (Fig. 2); a second set of grooves may run orthogonal to the first (Fig. 4) thereby providing a pattern of square or rectangular pyramids, or there may be three sets of grooves at 120 degrees to each other (Fig. 3). The depths of the grooves may be about the same as their width. Manufacture.-A patterned master plate may be pressed into a glass carrier whilst the latter is softened by heating. In another method, a master is coated with a thin film of Au-Pd alloy and electroplated with Cu, Ni, Cr, or Rh which is then stripped off and moulded to a glass sheet to constitute therewith the required cathode carrier member. In a further method, a metal mould formed from a master is attached under tension to a support ring, heated with the glass carrier under vacuum to a little above the softening point of the glass, and pressed into the glass by a block of carbon. The mould may be withdrawn or dissolved after cooling, or the assembly may be reheated under pressure before removing the mould. The mould may be pretreated, e.g. by oxidation, to ensure wetting of the glass. The carrier may be a fibre plate or a silica plate instead of glass.
