Title: Selective winning of lead from sulphide ores - by leaching with hot aq. hydro:fluorosilicic acid soln. contg. hydrogen peroxide and air so only lead is dissolved
IPC: C25C1/18
Filed: 1981-05-12
Abstract: The ore is subjected to at least one treatment in which it is oxidised in an aq. soln. of H2SiF6, so the Pb is dissolved. The oxidn. pref. employs a redox pair, esp. O2/H2O2 at 0.7-1.4 volts w.r.t. a normal hydrogen electrode. The milled sulphide is pref. mixed with a soln. of H2SiF6 contg. H2O2, while a gas contg. O2 is bubbled through the soln. The Pb is pref. reclaimed from the soln. by electrolysis, while the O2 liberated at the anode is collected and used in the leaching soln., which pref. is at max. 2.0 pH. The ore is esp. galena or its concentrates. A high yield of Pb is obtd. without dissolving other metals in the ores.

Title: Logic level combination generator for safety circuit testing - has memory array of which logic output signals without requiring scanning by computer
Inventor: LAVIRON ANDRE
IPC: G01R31/3181
Filed: 1981-06-09
Abstract: The generator can be set such that all or some of the combinations of two of its output signals are at logic 1, and the rest of its output signals are at logic 0. When associated with a failure simulator, the generator can be used to study the consequences of failures of components which are part of a nuclear power station safety system, and is intended to test printed circuit boards which have a high number of contacts. All contacts are inspected taken in pairs and a comparison is made with a reference p.c.b. A combination of signals is found without the need of the usual long and complicated scanning by a computer.

Title: Tubular thermoelectric installation for heat pump - uses insulated mechanical coupling between hot and cold interconnected fluid circulation systems
IPC: H01L35/30
Filed: 1981-12-03
Abstract: The installation has two interleaved banks of hot (4) and cold tubes (5) respectively, which are interconnected by thermoelectric junctions (1) sandwiched between hot walls (2) and cold walls (3). The several hot tubes (4) are coupled together near their ends (4a,4b) by two parallel hot mechanical structures (6,7). The cold tubes (5) similarly are coupled by parallel cold structures (9,10). The hot and cold structures are thermally independent but are fixed together mechanically by axial bolts (13) passing through successive hot and cold tube flanges (e.g. 6,9) via insulating collars (12). Alternatively, the mechanical coupling structures consist of a hot plate and a parallel cold plate, held together by transverse bolts, at each end of the two tube banks. The hot tubes pass through holes in the cold plates, and conversely.
