Title: Improvements in the Production of Metal Powder or Metal Granules
IPC: B22F9/08
Filed: 1967-05-24
Abstract: 1,189,172. Granulating metal. ELEKTRISKA SVETSNINGS A.B. May 24, 1967 [May 26, 1966], No. 24210/67. Addition to 1,107,115. Heading C7X In a method of disintegrating metal according to Claim 1 of Specification 1,107,115 (in which condensible vapour is mixed with a cooling agent, so that condensation attended by vigorous agitation and shock phenomena takes place, and molten metal is made to contact the condensing vapour and be disintegrated into particles which are collected in a quenching liquid) a molten metal stream is made to encounter a jet or stream of gas or vapour prior to its contacting the condensing vapour. Molten metal (e.g. stainless steel) may be discharged through outlet 13 from pot 14, and encounter a conically converging steam jet from slot 12 of nozzle 4 before encountering a condensing steam jet from nozzle 5 at y. Nozzle 5 produces a flat jet, and may supply saturated steam or a steamair mixture produced by entrainment of air. Some air may be entrained by a conical steam jet from outlet 13 and cool the interior of the tank in which disintegration takes place, or the atmosphere in the tank, which may be nitrogen or a noble gas, may be cooled by a water spray within the tank. The pressure of the steam supplied to nozzle 4 is less than 1kg/ cm<SP>2</SP>, so that the jet from nozzle 4 does not disturb the action of the jet from nozzle 5.

Title: Improvements in or relating to the cold separation of air
IPC: F25J3/04
Filed: 1951-10-17
Abstract: 708,664. Cold separation of air. BRITISH OXYGEN CO., Ltd., and SCHUFTAN, P. M. Oct. 14, 1952 [Oct. 17, 1951], No. 24266/51. Class 8 (2). In an air separation process comprising liquefaction and subsequent rectification wherein the cold supplied is equal to the average requirement of the plant, the temperature gradient in the rectification zone is automatically maintained substantially unchanged and independent of temporary variations in the refrigeration performance of the plant. A vapour pressure thermometer 6 is located at a point 7 of maximum temperature gradient in the low pressure zone of a conventional double column and the temperature gradient is maintained constant by a valve 4 actuated by a controller 5 and controlling flow at oxygen-rich liquid from the sump 1 of the high pressure zone through a line 2 to a tray 3. The capacity of the sump 1 is made sufficiently high to allow of variations in level caused by variations in demand by the low pressure zone. In a modification the temperature gradient is maintained constant by withdrawing excess liquid formed when the refrigeration applied exceeds the demand, storing it and automatically returning it to the rectification column when the cold demand exceeds the refrigeration supply.

Abstract: 859,486. Image reproducers. ENGLISH ELECTRIC VALVE CO. Ltd. May 26, 1959 [July 28, 1958], No. 24270/58. Class 97(1) Light from an optical image, formed for example on an X-ray screen, is collected by a plurality of small cup-shaped reflectors which cover small adjacent elemental portions of the image, each reflector connecting with a light guide, in the form of a thin tube or filament of glass or other transparent material, which conveys the light from each image element by repeated internal reflection to the other end of the light guide, all of these ends then being brought together to form an image surface of reduced size. With reference to Fig. 1, the cup-shaped reflectors 2 may be formed on a rigid base 3 with reflecting deposits on suitably shaped recesses. These are placed close to, and facing the image on the X-ray screen 1. Light which does not immediately enter the light guides 4 is reflected by the reflectors to the light silver coating 5 where it is again reflected substantially towards the ends of the light guides. Fig. 2 shows the reduced image-surface 6 formed by the other ends of the closely gathered light-guides placed close to the plane face 10 of a wedge-shaped block of transparent material so as to reduce scattering. Light from the reduced image is reflected by the mirror 11 at unit magnification on to the photocathode 7 of a television camera 8 for subsequent amplification and reproduction.
