Title: Process for the manufacture of hydrogen from methane or gases containing methane
IPC: C01B3/22
Filed: 1954-01-20
Abstract: Hydrogen is produced by passing methane through a bed of hot porous "virgin" coke, i.e. coke which has not previously come into contact with water or air.  The coke may be produced from a mixture of coal and lignite.  Oxides or salts of iron, aluminium, tungsten or molybdenum may be added to the coke, or the raw material used in the production thereof.  The coke may be used immediately after it is formed in a coking plant.  The methane may be admixed with steam which reacts with carbon deposited during the decomposition to produce hydrogen and carbon monoxide. It may also be admixed with air so as to burn the deposited carbon and provide the heat for the decomposition.  Alternatively air and methane may be passed through the coke alternately.

Abstract: 684,730. Electrolysis of alkali-metal sulphate solutions. MERCK, K., MERCK, F., and MERCK, W., (trading as MERCK, E.). Jan. 23,1951 [Feb. 25, 1950], No. 1731/51. Class 41. A process for the electrolysis of aqueous alkali-metal sulphate solutions using a mercury electrode, is characterized by the use of anodes surrounded by casings of non-conducting electrolyte-resistant material, the lower ends of the casings being only a little way above the surface of the mercury and the upper ends extending above the upper surface of the electrolyte, and the electrolyte being introduced so that it flows upwardly inside the narrow channels surrounding the anodes. In the arrangement shown, anodes A in the form of rectangular strips are provided in a vessel K along the bottom of which mercury is spread. Electrolyte is introduced through an inlet E. The anodes are surrounded by casings G closed underneath by fabric M, formed of fibres resistant to attack by the electrolyte. The casings may be closed at the top for recovery of oxygen formed during electrolysis. The electrolyte flows out through exits U to a chamber R provided with a fixed or adjustable overflow S. The amalgam formed by electrolysis flows under a wall T to a chamber in which it is decomposed by water and from which the alkali lye is discharged. The mercury is pumped back to the cell K, flowing beneath a wall Z. The base of the anodes and the fabric M may be inclined, as shown, to facilitate removal of hydrogen bubbles. Means may be provided for leading off oxygen and hydrogen separately from the apparatus.

Title: Improvements relating to apparatus for counting vehicles

Abstract: 727,413. Counting-apparatus. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 10, 1952 [Jan. 28, 1952], No. 2290/52. Class 106 (1). Apparatus for counting the wheels of vehicles passing a fixed location comprises a pair of electrical switches arranged on passage of a wheel to be operated in turn from and subsequently successively restored to their initial conditions with a period during which both switches are operated together with three relays arranged to be sequentially operated as a wheel passes, the last relay being arranged to operate only if the preceding relays have operated in correct sequence and being effective when operated to actuate a counter. A wheel travelling in one direction closes a first treadle switch and then a second while the first is still closed and finally the second only. Corresponding relays A, B are thus operated in'overlapping sequence. Relays X, Y and Z and a " Counter in " are associated with this direction of movement. When relay A operates, the circuit for relay X is closed over unoperated contacts of relay B. Relay X closes a holding circuit. When relay B operates, the circuit for relay Y is closed over operated contacts of relays B, A and X. Again a holding circuit is closed. When relay A is released, unoperated contacts thereof and operated contacts of relay Y energize relay 2 which completes a holding circuit over operated contacts of relay B and actuates the " Counter in." Since the circuit for relay Z extends over operated contacts of relay B, a correct count will be given even if the wheel, having reached the second switch, rolls back to operate both again before continuing its forward movement. Similarly three further relays are operated in sequence under control of the relays A, B for travel in the reverse direction and are associated with a "Counter out." When a wheel travelling, say, in the first direction is closing the second switch only, in addition to the relay Z operating, the first relay of the other set operates. Thus if the wheel returns without moving beyond the second switch, it is counted out as well as in. By arranging two sets of switches at the ends of a section of railway track, a check may be kept on the number of vehicles in the section.
