Patent ES-451182-A1 (ES)
Title: Process and apparatus for removing volatile components from synthetic resin
IPC: B29C48/76
Filed: 1976-09-02
Abstract: Elimination is effected from a molten mass, soln. or dispersion by introducing the preheated material into the base part of a horizontal extruder under a pressure corresp., at the preheating temp., at least to the satn. pressure of the volatiles. The material is heated as it advanced through the extruder so that evapn. of the volatiles begins as the material enters the extruder, the major part of the volatiles leaving the extruder through an orifice situated vertically above the inlet orifice. The treated material is then extruded. Very rapid and efficient elimination of volatiles is obtd. The process is capable of treating the plastic materials at high flow rates. Material having a very low volatiles content, e.g. 0.1 wt. %, can be obtd.

Title: Video disc preview apparatus
IPC: G11B9/06
Filed: 1980-10-24
Abstract: A video disc player apparatus having a preview feature. A signal pickup stylus (24) assembly is compliantly mounted (45) in a carriage assembly (20) for translating the stylus radially across the record. A transducer (23) responsive to user operated player controls (68) imparts translatory motion to the stylus relative to the carriage assembly and directed radially across the record causing the stylus to translate a prescribed number or record grooves per impulse.

Patent ES-8207016-A1 (ES)
Title: A method of manufacturing a veneer article by hot pressing.
IPC: B27D1/08
Filed: 1981-03-04
Abstract: When an article having a strongly profiled transition zone (17) between a substantially flat edge zone (16) and a flat or less strongly profiled central panel (9') is hot-pressed from a single veneer ply or a plurality of adhesively bonded veneer plies (6, 7, 8) cracks may occur in the transition zone of the finished article when the prior art is employed. This undesirable formation of cracks is prevented by effecting, at each corner of at least an outer veneer ply (6), an incision in the form of a gap (18, 19) which extends from the periphery of the veneer ply inwardly through the edge zone with by and large parallel edges and which continues in wedge form through the transition zone with the apex of the wedge located at the corner of the central panel where that panel joins the transition zone. The gap width is chosen such that the gap just closes as a result of the inward displacement of veneer material from the edge zone which accompanies the reshaping of the transition zone. The press tool is provided with stops (22) which abut the edges of the flat veneer ply and, thus, locate the ply exactly relative to the profiled portion of the tool. That portion (20) of the upper tool part (13), which moulds the transition zone, may be displaceable relative to the remainder of the tool and spring loaded towards the lower tool part (12).

Title: Recovering zinc from zinc-containing sulphidic material.
IPC: C25C1/16
Filed: 1982-04-20
Abstract: A process for recovering zinc from zinc-containing sulphidic material which also contains iron and lead includes leaching the material under oxidizing conditions at a temperature in the range of from about 130 DEG to about 155 DEG C. in aqueous sulphuric acid solution with a stoichiometric excess of sulphuric acid relative to the zinc content of the material of from about 50 to about 100% to produce an undissolved residue containing a major proportion of the lead and a leach solution containing a major proportion of the zinc and iron. The sulphur and lead containing residue is separated from the zinc and iron containing leach solution. Elemental sulphur is physically separated from the remaining lead-containing residue, and the remaining lead-containing residue is recovered. The zinc and iron containing leach solution is treated to recover zinc by feeding the solution to another process in which zinc-containing material is treated to recover zinc and which includes an iron-precipitation step.
