Patent GB-1129543-A (GB)
Title: Gas separation process
IPC: C01B3/56
Filed: 1965-12-21
Abstract: 1,129,543. Separating gases. UNIVERSAL OIL PRODUCTS CO. 21 Dec., 1965 [28 Dec., 1964], No. 54011/65. Heading B1L. In a cyclic and continuous 3-bed adsorption process for separating the components of a gas mixture, one of the components is selectively adsorbed at elevated pressure up to 34 atmospheres in one bed which the process stream enters at one end and leaves at the other, while simultaneously a second bed is being desorbed at reduced pressure down to 2.54 cm. Hg. abs., the desorbate leaving from an intermediate point of the bed, and a third bed is being repressurized for use as the sorber in the next phase of the cycle. During desorption, a portion of the process stream, or of the effluent, or a gas such as steam which is less readily sorbed than that being desorbed, is passed into the bed from both ends as a stripping aid, but the flow rate thereof is so controlled as to maintain a pressure differential between the ends and the intermediate point of the bed, desorbate being collected until this differential is less than 0.34 atmospheres, whereafter withdrawal of sorbate is continued at sub-atmospheric pressure until the adsorbent is reactivated. Applications include the separation of hydrocarbons, both from each other and from hydrogen in refinery recycle gases, the fractionation of air, the drying of gases, the purification of natural and other hydrocarbon gas, and the recovery of traces of carbon tetrachloride and perchlorethylene from dry cleaning plant vapours, and the choice of adsorbent, which may suitably be activated alumina or carbon, or molecular sieve or silica gel is dependent upon the application. A detailed flow sheet is provided.

Abstract: 1,122,343. Dry cleaning. H. GUNTNER. 5Dec., 1966 [3 Dec., 1965], No. 54261/66. Heading DIA. In a dry cleaning machine a cleaning agent is used which evaporates at usual ambient temperatures and pressures so the resulting vapour is compressed, separated out, cooled and then returned to storage tanks or back to the machine. Air and vapour are drawn out through a pipe 64 through a filter 22 and compressor 18 to an air/vapour separating chamber where the air is returned via pipe 42 to the cleaning chamber and the vapour passes through a cooler 32 where it may be cooled by ambient air (due to increased pressure caused by the compressor) and the liquid is then returned to storage tanks 10. Any vapour formed in the storage tank 10 escapes through the tube 56 and is reconverted to liquid. A distilling plant 48 is provided to clean the solvent after use and the air or vapour may be used to produce heating through pipes 52.

Title: Production of slabs for use in the lining of hot tops and the heads of ingot moulds
Inventor: HUGHES MALCOLM JOHN
IPC: B22D7/10
Filed: 1965-12-30
Abstract: Slabs of composition suitable for lining the head of an ingot mould are produced by forming an aqueous slurry of granular or powdered refractory, organic fibrous material and a binding agent, placing it in a horizontal slab mould, vibrating to settle the solids and form an aqueous supernatant layer, depositing on the surface of the slurry a dry, heat-insulating composition which absorbs the supernatant layer, compressing, and drying the slab formed after removal from the mould.  The refractory may be a silicate, silica flour, olivine, chamotte, alumina, or silica sand or a mixture thereof; the organic fibrous material may be paper pulp, cotton waste, rag stock, nylon fibre, polyester fibre or acrylonitrile fibre or a mixture thereof and the binder may be sodium silicate, a natural gum, urea-formaldehyde resin, phenol formaldehyde resin or furan resin. The slurry may also contain a fibrous refractory, e.g. asbestos, slag wool, metal fibres or ingredients which react exothermically on ignition, e.g. finely-divided aluminium, with one or more alkali metal or alkaline earth metal nitrates, iron oxide and manganese dioxide. The heat-insulating composition may have the same composition as that slurried or consist of granular or powdered refractory, e.g. kieselguhr, vermiculite, perlite, ball mill dust or dolomite, powdered organic absorbent, e.g. sawdust, woodflour or wheatflour and binder.

Title: Device for measuring tension and elastic modulus of a web
IPC: G01L5/08
Filed: 1970-11-23
Abstract: 1328661 Determining elastic modulus; determining tension in webs CONSOLIDATED PAPER (BAHAMAS) Ltd 23 Nov 1970 [24 Nov 1969] 55646/70 Headings G1S G1W A device for measuring or testing a directional characteristic of a web comprises a head 14, a cavity 28 with a mouth opening in the head, the mouth being shaped with substantially straight side edges and rounded ends, means for producing a pressure differential across the web under test in the region of the cavity for drawing a portion of the web into the cavity, means for sensing the deflection of the web into the cavity 30 and means responsive to the sensing means for indicating the value of the characteristic 72. As described the testing device 10 has two such heads and determines tension in a paper web and/or an elastic modulus of the paper web by drawing, by vacuum, a small area of the web into a cavity 28, 44 and measuring the deflection produced by means of a transducer 30, 46. A groove 26 on grooves 38, 40 to which a higher vacuum is applied holds the web in contact with the face 24, 42 of the sensing head 14, 16 respectively. An equation is given which gives tension and elastic modulus as a function of vacuum applied, deflection measured and aperture dimensions so that by using two heads 14, 16 with cavities of different dimensions to which the same vacuum is applied a pair of equations can be solved simultaneously to give both tension and elastic modulus. The testing device 10 is mounted on a rail 100, Fig. 4 (not shown) for traversing the web to obtain readings of tension and elastic modulus across the web. A series of holes 54 in plates 20 fed with air under pressure, holds the web against the plates by a "coanda" effect.

Abstract: 1434829 Valves GENERAL MOTORS CORP 13 Dec 1973 [13 Dec 1972] 57736/73 Heading F2U [Also in Division F1] A valve assembly 56 for controlling recirculation of I.C. engine exhaust gas comprises a closure member 90 disposed between exhaust gas inlet and outlet passages 54, 58 respectively and carried by a stem 92 supported by a diaphragm 108 defining a closed chamber 110 with top cover 104. Chamber 110 is subject via a passage 122 in stem 92 and a restricted orifice 124 to the pressure in a region 82 immediately upstream of closure 90. The latter is positioned by diaphragm 108 so as to maintain that pressure substantially constant. Diaphragm 108 is biased to the valve closed position by a weak spring 112 assisted by a second spring 128 which comes into operation when closure 90 has reached the fully open position, thus reducing the response of diaphragm 108 to further increases in exhaust back pressure and ensuring that closure 90 does not prematurely engage orifice member 84 to shut-off recirculation. Heat conduction to diaphragm 108 is reduced by an asbestos disc 114 disposed between lower and upper housing members 72, 96 respectively and retained by intermediate member 116. The latter also houses graphited asbestos stem sealing discs 118 stacked above a steel washer 120. Top cover 104 carries a perforated baffle 138 to prevent any ice that might form on the underside of the cover from dropping on to diaphragm 108 and interfering with valve operation.
