Title: Sieve drum dryer for drying a continuous fleece of fibrous material
IPC: F26B13/16
Filed: 1955-12-23
Abstract: 799,832. Drying fibrous fleeces or webs. FLEISSNER, H., FLEISSNER, G., and FLEISSNER, H., [trading as FLEISSNER & SOHN MASCHINENFABRIK]. Dec. 23, 1955, No. 36992/55. Class 34(1) In a sieve drum drying apparatus for drying fleeces of fibrous material and having for example drums 10, 11, 12 vertically staggered in an upper and a lower row the distance between adjacent drums in each row is not less than one quarter of the drum diameter and measured as a percentage of the drum diameter is not less than eight times the numerical value of the designed air velocity through the fleece measured in metres per second. In a modification, the drums are arranged in a single row. The drums may be driven, Fig. 4, by endless steel bands 23 passing around the edges of the drums and around a drawing-in sieve drum 22, cover plates 24 preventing the formation of eddies by which the fibrous web is destroyed from the edge. A leading strip of material impermeable to air may be secured to the bands 23. A perforated plate 25 above and below the drums renders in-flowing suction air uniform in direction of flow.

Title: Sheet material
IPC: A61F13/02
Filed: 1962-10-05
Abstract: 987,275. Adhesive dressings. JOHNSON & JOHNSON. Oct. 5, 1962 [Oct. 6, 1961], No. 37790/62. Heading A5R. An adhesive dressing comprises a fibrous layer with a discontinuous air-pervious adhesive on one face and an air-pervious synthetic film layer on the other. The fibrous layer 13 may be woven or non-woven and the film backing 11  has numerous small openings over its entire area, preferably of microporous size, i.e. of less than 1 micron in diameter, so that air-borne bacteria cannot pass through it. The open areas 14 in the pressure-sensitive adhesive layer, however, are sufficiently large not to become closed by flow of the adhesive during handling and storage of the tape. It is therefore preferred to apply closely spaced lines of adhesive across the surface. In a modified form a film layer, previously bonded to a fibrous layer, is perforated by heated pins of between 0À003 and 0À008 inch diameter. Specification 819,635 is referred to.

Title: Method for discharging mixture of particulate solids and fluids from high pressure vessel
IPC: B01J38/00
Filed: 1966-08-26
Abstract: 1,146,060. Catalytic process. CITIES SERVICE RESEARCH & DEVELOPMENT CO. 23 Aug., 1966 [25 Aug., 1965], No. 37813/66. Heading B1F. A method of discharging particulate solids from a solid-liquid-gas mixture discharged from a high pressure vessel having an effluent stream comprises discharging the mixture from the vessel at a low pressure differential of no more than 150 p.s.i. to a fluid-solid separation zone, continually venting liquidgas substantially free from particulate solids from the fluid-solid separation zone to a point in the effluent stream until the venting of the liquid gas is decreased by accumulation of particulate solids in the fluid-solid separation zone, terminating both the discharge of the solid-liquid-gas mixture from the high pressure vessel and the venting of the liquid-gas to the effluent stream and subsequently recovering particulate solids from the fluid-solid separation zone. The invention is particularly described with reference to a plant for hydrocracking hydrocarbons catalytically. Additionally the plant may embrace a fractionating device for dealing with the liquid phase.

Title: Current Detector
Inventor: EVANS BRIAN ARTHUR
IPC: G01R15/24
Filed: 1967-08-17
Abstract: 1,170,540. Current measuring. MULLARD Ltd. July 18, 1968 [Aug. 17, 1967], No.37871/67. Headings G1A and G1U. In a system for measuring current on a high voltage conductor C by using the Faraday effect, interference effects caused by current in an adjacent conductor TC are reduced by using two spaced Faraday effect bodies Y1, Y2 spaced in the field of the current to be measured, a plane polarized infrared beam being passed through the two bodies in turn in such a direction that the effects on the two bodies of the field due to the adjacent current effectively cancel. In one system infrared light is directed via a fibre optic FO1 to a polariser P1 through one body Y1 and is then reflected by two mirrors (to give 360 degrees phase change) through the second body Y2 analyser P2, fibre optic FO2 to a detector D. The current being measued may be a very high A. C. which will result in a modulated output from the detector which must be demodulated. Alternatively A.C. may be measured, in which case the effect of attenuation in the light path is reduced by inserting a further body to which a reference A. C. is applied and determining the depth of modulation at the detector, which represents the ratio of the reference A.C. to the unknown D.C. In alternative arrangements, both Faraday bodies may be between the conductors C and IC Fig. 3 (not shown) and the system of mirrors M1, M2 may be replaced by a U-shaped light guide Fig. 5 (not shown), a further analyser and polarizer being inserted in the light path since such a guide will cause the loss of any polarization information in the light passing into it. The provisional Specification describes an arrangement using any one magneto optic body set in a magnetic shield surrounding the test conductor to reduce external interference effects.

Abstract: 884,590. Cold separation of gas mixtures. AIR PRODUCTS Inc. Nov. 26, 1958, No. 38055/58. Class 8(2). Separation of relatively high boiling point impurities e.g. carbon dioxide and heavy hydrocarbon from a gas mixture e.g. air undergoing rectification in a conventional double column 30, 32 Fig. 1 after being cooled in a heat exchanger 12 transversed by separated constituents is effected by diverting through a duct 13 a portion of the partly cooled air from heat exchanger path 11 expanding in a turbine 14 without condensation of impurities and passing it to a phase separating vessel 20 together with the remainder of the air from a path 17 after expansion and partial liquefaction at a valve 18 thereby concentrating the condensed impurities in the liquid collecting in vessel 20, feeding the gas and liquid through ducts 21, 22, 25 to the high pressure column 30, withdrawing through a duct 40 impurity-rich liquid from the base of column 30 and passing it through alternating filter beds, 43, 44 and absorbers 47, 48 and subsequently expanding at a valve 52 into the low pressure column 32. In a modification the impurity-rich liquid leans the base of column 30 Fig. 6 through a duct 100 and is forced into a phase separating chamber 80 by an injector 101 using the major portion of the cold incoming air as the working fluid and the separated liquid from chamber 80 traverses a duct 103 to the alternating filters and absorbers.
