Title: Process for the manufacture of alumina and of sulphate of aluminium and products when obtained by said process
IPC: C01F7/743
Filed: 1925-09-08
Abstract: Crude aluminium sulphate solution, obtained for instance from bauxite, after reduction of the iron to the ferrous state is treated in the presence of iron by heating or electrolysis or both, so as to produce nascent ferrous oxide in the solution which causes the formation of ferrous sulphate and basic aluminium sulphate, any titanium present being precipitated as oxide.  The electrolysis may be effected with direct or alternating current with the use of iron electrodes.  When heating alone is employed the iron is present in the state of small particles.  After the electrolytic or heat treatment, the solution is poured into a suitable quantity of water, when basic aluminium sulphate is precipitated.  The basic sulphate may be converted into normal sulphate by treatment with the necessary quantity of sulphuric acid, or into alumina by heating, in which case the sulphuric acid is recovered.

Title: Counter control circuit for an analog to digital converter
Inventor: VENNING SELBY GREGORIE
IPC: H03M1/00
Filed: 1968-05-10
Abstract: 1,223,617. Reversible counter; selective signalling. GENERAL ELECTRIC CO. 10 May, 1968 [26 June, 1967], No. 22418/68. Headings G4A and G4H. An input circuit to a reversible counter comprises two bi-stable elements which respond respectively to the leading and trailing edge of a clock pulse and which must be in like condition to pass a clock pulse to the counter. As applied to a continuously operating analogue to digital converter a - ve analogue input is balanced at 16 with a +ve binary. weighted current from a D/A converter 12 and a small deadband current source 14. If the analogue input increases in magnitude a comparison amplifier 10 goes to 1 so that the leading edge of the next clock pulse sets bi-stable 26, Fig. 5c, this condition persisting while 10 remains at 1. The trailing edge of the clock pulse, after passing through inverter 34, combines with the 1 output from 26 to set bi-stable 32, Fig. 5d. The resulting 1 output from inverter 42 conditions the counter for counting up, and provided the counter is not at full capacity AND gate 46 passes the following clock pulses to the counter. When balance is achieved at 16 the comparison amplifier 10 oscillates between 0 and 1 with bi-stables 26, 32 also reversing at the leading and trailing edges of all clock pulses, the output 28 from bi-stable 26 switching deadband current source 14 alternately on and off. As the outputs of 26 and 32 are always unlike at the occurrence of an inverted clock pulse, AND gates 44, 46 are blocked. If now the analogue input decreases in magnitude the circuit operates in complementary manner to send count-down pulses to the counter, Figs. 5 (e.g.), provided the counter is not empty.
