Title: Mercury cathode electrolytic cells
Inventor: SHAW JOHN PETER HODSON
IPC: C25B15/04
Filed: 1964-08-12
Abstract: <PICT:1088162/C6-C7/1> In a mercury cathode cell which is producing chlorine by electrolysis of alkali metal chloride solution the anode is set in accurately-spaced relationship to the mercury cathode surface by measuring the electrical conductance across the electrolyte gap between the anode and cathode, and then adjusting the spacing between anode and cathode so that the said conductance is brought to a predetermined value.  The conductance measurement may be made by measuring the voltage drop between the cathodic base-plate and a probe a point on the anode conductor outside the cell, subtracting therefrom the reversible cell potential between anode and cathode and the chlorine over voltage, and in the latter case the potential drop is the anode connector structure, and relating the voltage drop hereby obtained to the measured current flowing. In the form shown the cathode is formed by a layer of mercury 5 flowing upon the metal base-plate 1.  The anode comprises an anode block 6, and shaft 7 to which electric current is fed via bus-bar 9 and shaft 8. Conductivity measurements between anode and cathode are made using a titanium wire passing through a hole in the cell cover, which is sealed by a resilient bung 17, and attached to a titanium terminal screw 19, and a connection to the base-plate 1 at the point X. Adjustment of the anode is produced by rotation of the flanged screw adjuster 12.  The cell may contain a plurality of anodes which may all be adjusted to a similar inter electrode gap as described above. The predetermined value of the electrolyte gap conductance may lie in the range 7,000-10,000 mho/m2 of cathode surface.

Abstract: 656,918. Powder metallurgy. DOMINION MAGNESIUM, Ltd. Dec. 20, 1948, No. 32882. Convention date, Nov. 4. [Class 83 (iv)] A method of sintering compacts of titanium, chromium, hafnium, vanadium or zirconium comprises heating the compact in the presence of barium, calcium, lithium, magnesium or strontium at a temperature above the melting point of the alkaline earth metal and at the desired sintering temperature. To sinter titanium compacts, the powder is first pressed, without the use of lubricants, and placed, with calcium, in a mild steel container. The closed container is placed in the upper cool zone of a furnace and the furnace is filled with argon to above atmospheric pressure. The container is then sintered at 1000‹ C. Alternatively, the compacts are placed in a mild steel basket and lowered into molten calcium under an argon covering, or are suspended in calcium vapour. The compacts are cleaned with dilute hydrochloric acid. The sintering time is substantially the same as in high vacuum procedure. It is stated that sodium, cadmium and lead are unsuitable.
