Patent GB-684224-A (GB)
Title: Improvements in process for the preparation of a sodium bisulfite solution from aqueous salt solutions
IPC: B01J39/00
Filed: 1951-07-10
Abstract: Sodium bisulphite solution is prepared by treating an aqueous solution containing a sodium salt of a weakly acidic volatile acid, such as carbon dioxide or hydrogen sulphide, with a cation exchange resin in acid form and treating the resulting sodium resinate with sulphurous acid to recover the resin in acid form and produce a solution of sodium bisulphite.  The volatile acid is evolved and in the case of hydrogen sulphide may be collected and burnt to produce sulphur dioxide for use in the process.  Ion exchange resins containing carboxy or phenolic hydroxy groups or both are particularly applicable.

Abstract: 1,128,073. Reactors. UNITED STATES ATOMIC ENERGY COMMISSION. 18 April, 1966 [12 Oct., 1965], No. 16832/66. Heading G6C. In a sodium cooled fast breeder reactor, the fission, fertile and reflector zones are concentrically disposed to provide a uniform power distribution across the cylindrical core. Positive reactivity effects due to coolant voidage are reduced. An annular fission zone is concentrically disposed between inner and outer annular breeder zones. An outer annular reflector surrounds the assembly and a - cylindrica reflector occupies the central position, within the inner annular breeding zone. To prevent power peaks at the fuel periphery due to the return of neutrons from further reflectors which enclose the fuel zone, annular zones of breeder material are inserted between the further reflectors and the fuel to absorb reflected neutrons. The end surfaces of the cylindrical core are covered by breeding and reflector layers. Reactivity control may be effected by neutron absorbing rods or by reflectors.
