Title: Process for the electrolysis of alkali metal salts and electrolytic cell therefor
Inventor: MURAYAMA KOICHI
IPC: C25B1/36
Filed: 1964-03-31
Abstract: <PICT:1068991/C6-C7/1> In a process for electrolyzing alkali metal salt solutions using a mercury cathode and an anode 26 of titanium plated with platinum, a current density of over 100 Amps/dm2 and an interpole distance of less than 3.5 mm, the resulting foam layer which forms on the surface of the electrolyte is removed therefrom, e.g. by allowing (Fig.5) or by causing, Fig. 6 (not shown) the foam to overflow, or by suction means Fig. 7 (not shown). The foam may be delivered thereby to a gas-liquid separator.  The cell shown comprises a circular electrolysis chamber 21; a cathode plate 25 to which mercury is fed via inlet 23; a liquid-gas separating chamber 30 into which the foam and saline water overflows through the V-shaped channels formed by the serrated edge of wall 28, the saline water being discharged therefrom via outlet 29, and chlorine gas via outlet 31; and an amalgam separating chamber 33 into which the mercury flows via the discharging port 32. Overflow of saline solution and foam may be caused by means of a rotary impeller 35 Fig. 6 (not shown) or by means of a multiplicity of jet nozzles extending horizontally at the level of the top of the dividing wall 28.  Using high current density the anode surface may be positioned below the surface level of the mercury cathode, short-circuiting not resulting.  Suitable anodes are described in Specification 1,068,992.

Title: Improvements in or relating to non-staining compositions and methods for preservation of timber
IPC: B27K3/52
Filed: 1961-04-12
Abstract: Wood-preserving solution has a pH in the range 7.2 to 8.5 and is formed by dissolving an alkali-metal pentachlorophenate and a greater amount of an alkali-metal arsenate in water.  Preferably, the solution contains also a water-soluble chromium salt and an alkali-metal fluoride.  The preferred composition contains sodium pentachlorophenate, disodium arsenate (Na2HPO4), sodium chromate and sodium fluoride in the ratio by weight 1 : 2 : 3 : 2.  The salts can be formed into a dry composition, which can be stored until required. If necessary, the pH can be adjusted to within the above limits by the addition of soda ash or acid.  Wood may be impregnated with these compositions by the conventional empty- and full-cell methods.  The Specification also describes for purposes of comparison the impregnation of wood with sodium pentachlorophenate alone, sodium pentachlorophenate buffered with sodium carbonate and bicarbonate, and the inorganic salts without any pentachlorophenate.

Title: Method of removing decay heat from a nuclear reactor in an emergency
IPC: G21C15/18
Filed: 1976-04-01
Abstract: 1536350 Emergency cooling arrangement HOCHTEMPERATUR - KERNKRAFTWERK GmbH (HKG) GEMEINSAMES EUROPAISCHES UNTERNEHMEN 1 April 1976 [12 April 1975] 13286/76 Heading G6C In the event of a fault or faults occurring in a gas-cooled high temperature nuclear reactor whereby the normal operational systems of the reactor are inadequate to remove the decay heat, this is effected by introducing water into the reactor core. It is admitted to be a catastrophe measure, in that the reactor becomes unusable without major servicing. The water is preferably desalinated and a metered amount is introduced at the top of the core after neutron flux has been shut down by introduction of absorber rods. Alternatively absorber material, e.g. boron compounds may be added to the water. Thermal shock is stated to be minimized by a film of steam which forms over the spherical core elements. Condensed steam from the core may be recycled and safety valve may be provided to relieve excess steam pressure within the pressure vessel in cases where the integrity of the vessel has not been destroyed.
