Title: Improvements in the hydrometallurgical production of aluminium sulphate
IPC: C01F7/743
Filed: 1962-06-14
Abstract: Normal aluminium sulphate hydrate Al2(SO4)3.16-18H2O is produced from an alumina bearing siliceous material containing iron impurities by leaching, e.g. for 1 1/2 hrs., the material with at least a stoichiometric quantity of sulphuric acid of concentration 40-80% by weight at 100 DEG  C. to acid boiling point, separating the pregnant liquor from the solid residue and crystallizing by cooling the solution, the sulphuric acid concentration of the pregnant liquor being adjusted to 30 to 46% by weight before crystallization.  The sulphuric acid may be employed in at least twice the stoichiometric amount and preferably four times the weight of the raw material.  The pregnant liquor may have an aluminium sulphate concentration of not greater than 20% by weight and is separated at about 60 DEG  C.  A reducing agent may be used before the liquor is separated from the solid residue to reduce ferric to ferrous, e.g. SO2 which may be used at 70-71 DEG  C. After separation, e.g. by centrifuging, filtration or multi-stage decantation, the crystals may be washed with aqueous sulphuric acid or water and then may be neutralized, e.g. by heating to dissolve them in their water of crystallization, adding to the solution at least enough alumina trihydrate to neutralize all the acid present and cooling the solution.  The spent liquor from the crystallization process may be recycled after adjustment of the acid concentration and volume. Material difficult to leach may have a preliminary acid or thermal cracking treatment. Thus finely divided raw material may be mixed with 60-98% H2SO4 and digested to a solid cake-like consistency. It may then be heated to 200 DEG  C. to dehydrate gelatinous silica, broken up and used as feed for the leaching process.

Title: Improvements in or relating to means for counting electrical impulses
IPC: H03K21/00
Filed: 1945-09-14
Abstract: 606,680. Electrical counting apparatus. STANDARD TELEPHONES & CABLES, Ltd., and RIDLER, D. S. Sept. 14, 1945, No. 23773. [Class 106 (i)] An electrical counting-apparatus employs thermistors. A momentary depression of a key K1 through contacts RS4-6 heats the filaments H of thermistors T20 in the rings TR10, TR100, TR1000. The resistance R of T20 becomes conducting to heat the filament H of T1. The impulses to be counted open and close contacts IS so that when a key K2 is closed, these impulse cause the energization and release of relay A. When contact A1 moves to the right, T1 conducts and heats the filament of T2, the circuit through T20 being broken. When contact A1 releases, T2 conducts and heats the filament of T3, while the circuit through T1 is broken. This process repeats for each impulse, each tenth impulse rendering T19 conducting and energizing relay B which via contact B1, B2 adds one into the ring TR100, and into a register REG10. Similarly, each time the ring TR100 is completed, one is added into the ring TR1000 and into the register REG100.
