Abstract: 1,227,022. Treating bauxite. PECHINEY COMPAGNIE DE PRODUITS CHIMIQUES ET ELECTROMETALLURGIQUES, and SOC. APPAREILS ET EVAPORATEURS KESTNER 19 March, 1968 [20 March, 1967], No. 13180/68. Heading C1A. Bauxite is subjected to the action of an aqueous solution of caustic soda and sodium aluminate (to achieve a dissolution of the alumina content of the bauxite) in a series of pressure stages of increasing temperature. Any intermediate (or final) stage 21<SP>1</SP> receives the reaction suspension from the preceding stage 21 and is heated by a corresponding member of a series of exchanger expansion stages 24, 24<SP>1</SP>, these expansion stages being supplied in series with the hot aluminate/"red muds" suspension from the final pressure stage. Water vapour from each expansion stage 24, 24<SP>1</SP> heats the suspension in each pressure stage to close to its boiling point by direct injection in a mixing re-heater 22, 22<SP>1</SP>. The re-heated suspension remains in a reservoir for less than 1 hour while the solubility equilibrium for the temperature is reached. Circulation means pass into the following stage the contents of one stage increased by the condensed steam. The suspension leaving the final stage is heated by live steam and then passed back along the series of expansion stages. Part of the vapour produced in each expansion stage is used to heat the next expansion stage while the remainder is passed to the appropriate mixing reheater.

Abstract: 1,237,980. Magnetic switches. INTERNATIONAL BUSINESS MACHINES CORP. 15 Dec., 1969 [14 Jan., 1969], No. 60958/69. Heading G4H. [Also in Division H1] An electric switch device 23 supplies a series of signals to a control circuit 22 as a polarized disc 51 is rotated past a sealed magnetic reed contact device 40. A signal may be applied to an input cable 25 to require the movement of a member 11 for a selected distance and direction. To move the member 11 to the left the circuit 22 energizes a coil 21 to release a latch 15 allowing rotation of a shaft 14, and consequent movement of member 14, by a friction clutch 13 driven by a shaft 12. The disc 51 is mounted on the shaft 14 and when its rotation has caused operation of the contact device for a number of times corresponding to the required movement of the member 11 the circuit 22 will de-energize the coil 21 so that the shaft 14 is again latched. If the member 11 is to be moved to the right the circuit 22 energizes a coil 24 to urge a pressurepad 34 against a spring 31 to couple the shaft 14 to a continuously rotating shaft 32.

[Also in Divisions G2 and G3] A fuel injection system for an I.C. engine operable with mixture compression and separate ignition comprises a fuel valve operable to determine the fuel quantity injected into the intake manifold, means for measuring the static and total pressures of the inducted air flowing in the intake manifold, at least one fluidic amplifier element for amplifying the static and total pressures and means for controlling the fuel valve responsively to the amplified pressures. The static P 1  and total pressure P 2  are fed through fluidic amplifers 7 and 8 to chambers 12 and 11 of a pressure regulator. The pressure differential causes diaphragm 10 to act on an adjusting member 14 connected to a valve member 20 which controls the flow of fuel by-passed from chamber 18 back to reservoir 22. Fuel from reservoir 22 is supplied to the fuel injector 26 through a restrictor 24 by a pump 23, the pressure upstream and downstream of the restictor being respectively communicated to chambers 17 and 18 to act on diaphragm 15. The pressure differential across diaphragm 15 acts in opposition to the pressure differential across diaphragm 14 to cause the valve member 20 to take up an equilibrium position which allows fuel in excess of the desired quantity to be by-passed back to the reservoir 22.
