IPC: C22B3/10
Filed: 1981-03-19
Abstract: The process is used for direct treatment of finely crushed impure pyrites or for treatment of the matte and dust-laden gas from smelting the pyrites with a non-oxidising gas at elevated temp. It comprises (a) (i) oxidising roasting of part of the pyrites or the matte, (ii) sulphatising roasting of the product with the rest of the pyrites or matte to produce sulphates of the metal values and iron oxide and (iii) leaching to produce a soln. contg. the metal values and an insoluble iron oxide residue used for iron prodn.; (b) separating the metal value-contg. dust from the gas and either (i) passing the dust to step (a) (ii) followed immediately by arsenic removal or (ii) subjecting the dust to a separate sulphatising roasting and leaching operation followed by disposal of the arsenic-contg. iron oxide residue; and (c) condensing sulphur from the gas. The process recovers Fe, Cu, Zn, Pb, Co, Ni, Cd, Ag, Au and S from impure pyrites (e.g. used for sulphuric acid prodn.) and iron matte (e.g. from arc melting of pyrites).

Title: Electrical transformer for e.g. ionisation chamber - has mineral piezoelectric transducer mechanically connected to piezoelectric polymer transducer
Inventor: MICHERON FRANCOIS
IPC: H01L41/107
Filed: 1981-05-19
Abstract: The transformer comprises a primary piezoelectric transducer (3) mechanically coupled to a secondary piezoelectric transducer (6). The primary transducer (3) is made from a mineral piezoelectric material and the secondary transducer (6) is made from a piezoelectric polymer. The mechanical coupling between the piezoelectric transducers (3,6) can be made, for example, by a lever (5). The mechanical stress applied to the secondary piezoelectric transducer results from a deformation of the primary piezoelectric transducer. This deformation can be transverse or parallel to the inducing electrical field. Electrodes (7,12) charged by the electrical field induced into the secondary transducer (6) can be parallel or normal to the deformation of the polymer.

Title: Magazine for pneumatic conveyor - uses chambers fixed to endless belt and driven by cam actuated pivoting fingers on rotary discs
Inventor: FAJEAU JACQUES
IPC: B65G51/32
Filed: 1981-06-09
Abstract: The cannister-magazine comprises a movable endless chain of chambers (5), and may be used in a pneumatic conveyor and storage system at a bank. Each chamber is mounted on square plates (8) of which the inner and outer sides are fitted with rollers (6) and attach to a belt (13) respectively. The rollers run on rails (3) whilst the belt follows an approximately elliptical path around idling pulley wheels (2a) on vertical axles (18,19). Movement is transmitted to the chain by freely pivotable fingers (32) mounted on a plate (25) or plates in turn mounted on an axle, the fingers having a heel (33) which co-operates with a fixed cam (34) as the plate rotates. The cam causes fingers to pivot over and house onto the outer wall of a chamber, the fingers retracting under gravity as the plate rotates a half turn.

Title: Trolley (barrow) with two adjustable wheels.
IPC: B62B1/12
Filed: 1982-04-09
Abstract: The invention concerns trolleys (barrows) with two wheels designed for transporting provisions or baggage. The two wheels of the trolley (barrow) according to the invention are placed on a frame which is articulated on the chassis, this frame being held in place by a second frame forming a brace. By lifting up this bracing frame against the chassis a second position of the wheels with respect to this chassis can be obtained.

Title: Method of autoadaptive regulation of the angle of ignition advance of a heat engine with controlled ignition.
Inventor: NGUYEN HUU-CAN
IPC: F02P5/145
Filed: 1982-07-27
Abstract: According to the invention, an iterative operation of searching for the optimal value theta opt of the angle of advance is performed by periodically adding an increment of angle of advance DELTA theta to the instantaneous angle of advance theta 0 and by then detecting the instantaneous speeds N1t and N2t which correspond to the angles of advance theta 0 and theta 0 + DELTA theta , and the direction of change DELTA N of the speed of the engine is determined so as to correct the angle of advance theta 0 in order that the variation DELTA N be as small as possible, or even zero, so that the angle of advance theta 0 is kept close to its optimal value theta opt. Under transient conditions, a "floating chart" is superimposed by taking account of a curve of advance versus speed of the engine. Usable for regulating the ignition advance of the engines of motor vehicles.
