Title: Converting metal sulphides to sulphates
IPC: C01B17/06
Filed: 1971-01-27
Abstract: Metal sulphide contg material is convertd into the corresponding sulphates by (a) reacting the material with sulphuric acid in a reaction zone at 150-300 degrees C during a period sufficient to convert at least a major proportion of the metal sulphide into the corresponding sulphate, (b) withdrawing sulphur from the reaction zone by passing an inert gas through the reaction zone to remove sulphur essentially at the rate it is formed during the reaction, and (c) recovering the formed metal sulphate. A wide range of sulphide minerals can be converted into sulphates, esp. of Cu, Pb, Zn, Ni or Fe. The quantity of sulphuric acid required for the reaction is reduced to a minimum, and the time required for the reaction is only 20% of that required in previous processes.

The complete blank may be subjected to plastic deformation, after which the sections which are to be non-magnetic are heated at least once to 1000-1350 degrees C. After deformation, the magnetic sections may also be heated at 450-850 degrees C, for 0.5-200 hrs. The alloy may contain in (wt %) 0.03-0.3 C, 12-17 Cr, 30-55 Co is not >7, Mo, balance Fe. A blank can be provided with a large cross-section on the end which is to be magnetic and drawn through a die plate in which the hole is slightly larger than the portion required to be non-magnetic, i.e. no deformation of the latter portion occurs. Magnetic props. depend on the degree of deformation e.g. Saturation Induction Bs is not >21000 G, Residual Induction Br is not >6500 G, and Coercive Force is not >230 Oe, while the sections not subjected to plastic deformation remained non-magnetic.

Title: Automatic programmed tariff changer for telephone exchanges - allows changes to occur on particular days for entire year
IPC: H04M15/10
Filed: 1974-09-25
Abstract: An automatic tariff changing device for use in telephone exchanges is described, which allows the days to be specified on which a different tariff is chargeable, and which then operates automatically for an entire year. The clock rate depends on the distance called and also on the device which consists of a matrix conductor array having thirty two columns, corresponding to days per month, and twelve rows, corresponding to months of the year. Each matrix intersection point represents a particular day of the year, and if such a point is specified, or conducts, a different tariff rate is chargeable. The column conductors are switched effectively to earth one at a time under the control of a 6 bit binary counter, whilst an output is taken from one row at a time under the control of a 4 bit counter.
