Abstract: 731,259. Flow meters. ELLIOTT BROS. (LONDON), Ltd. May 29, 1953 [March 3, 1952], No. 5566/52. Class 69 (1). Apparatus for measuring the rate of flow of a liquid or other fluid through a tubular conduit 1 includes a preferably adjustable aerofoil element 2 mounted within the fluid in the conduit, and a flow-indicating means responsive to the difference between a first fluid pressure at a position on the surface of the aerofoil element and a second fluid pressure within the conduit and upstream or otherwise remote from the aerofoil element. As shown, the element 2 is substantially rectangular in plan but has a curved leading edge 32, and is carried by a tube 5 rotatably mounted in a stuffing box 13. Its bore 24 may terminate at 25 in its upper surface, or at 27 in the centre of its trailing edge 26, branch bores 28, 29 opening respectively at the corners 30, 31 of the trailing edge. The two fluid pressures may be applied inside and outside a pair of bellows ,secured to the ends of a beam pivotally mounted inside a casing on a shaft. The movements of the shaft are transmitted to the exterior of the casing by a magnetic coupling and thence by means of an amplifying gear train to apparatus as described in Specification 405,043, [Group XXXVIII], which generates an electric current proportional to the angular deflection of the shaft. This current may then be amplified by a magnetic amplifier and the resultant current caused to operate an indicator or recorder. Alternatively, the shaft may be coupled by an amplifying gear train to a second shaft within the casing and carrying a pointer passing over a dial visible through a transparent window in the casing. According to the Provisional Specification the aerofoil element may be welded to the inner wall of the conduit, and the magnetic amplifier may be of the kind described in Specification 629,287, [Group XXXIX].

Patent GB-399526-A (GB)
Title: Improvements in or relating to the conversion of methane into other hydrocarbons
IPC: C07C2/76
Filed: 1932-02-26
Abstract: Methane is converted into other hydrocarbons of low molecular-weight, such as ethylene and ethane by heating at 350-850 DEG  C. in contact with catalysts comprising metallic nickel, cobalt, copper, or zinc in the solid or liquid state.  Promoters such as aluminium oxide or hydroxide or alkaline earth compounds, and also carriers such as kieselguhr, pumice, silica gel or carborundum may be employed.  The formation of ethane is favoured by relatively low temperatures, short time of contact, and unactivated catalysts or catalysts of low activity, whereas the production of ethylene is favoured by more strenuous conditions. Pressures below or above atmospheric may be employed, but preferably not much above atmospheric, such as 1-5 atmospheres. The catalyst may be used in the form of a lining to the reaction tube, especially when narrow tubes are used, which may be lined with nickel; or the catalysts may be used in a liquid bath, for instance, they may be suspended in molten halides of alkali or alkaline earth metals, or molten metals such as lead may be employed in the bath.  The methane may be mixed with other hydrocarbons or with different gases or hydrogen.  The reaction product may be further treated in any suitable way, except treatment to effect polymerization; for instance the vapours may be recirculated over the catalyst, preferably after first removing the ethylene formed, such removal being effected for instance by absorption in sulphuric, phosphoric, or hypochlorous acid or in active charcoal or silica gel. In an example, a gas containing 60 per cent of methane and 20 per cent of ethane is repeatedly passed through nickel-lined reaction tubes at 600 DEG  C. containing a catalyst obtained by depositing nickel oxide and calcium carbonate on pumice and reducing the product in hydrogen; the time of contact is 1 minute at each cycle.ALSO:A catalyst for the conversion of methane into other hydrocarbons of low molecular weight such as ethylene and ethane is made by depositing nickel oxide and calcium carbonate on pumice and reducing in hydrogen.
