Patent ES-388337-A1 (ES)
Title: Manufacture of insulated electric cables
IPC: B29C48/32
Filed: 1971-02-16
Abstract: In the manufacture of an extruded covering on a continuously advancing core by passing the core through the core tube of an extrusion machine which applies a continuous covering on to the core and effecting continuous treatment of the covering by passing the covered core through a chamber sealed to the extrusion machine and containing a fluid medium at super-atmospheric pressure, fluid under pressure is injected into the interior of the core tube of the extrusion machine. The injected fluid is maintained at a pressure which is less than that of the fluid medium by an amount such that the pressure difference across the extruded covering at the extrusion orifice is sufficient to cause the extruded covering to collapse firmly on to the core as it emerges from the extrusion machine but is insufficient to force the extruded covering back along the core tube. The pressure difference is preferably automatically maintained constant by a differential pressure control device associated with the chamber and with the core tube.

Title: Process for purifying phosphoric acids by neutralization with an alkali metal hydroxide and/or carbonate
IPC: C01B25/30
Filed: 1971-07-03
Abstract: Phosphoric acids produced by subjecting phosphate ores to wet-processing with mineral acids are purified by neutralizing them in a four step process by means of an alkali metal hydroxide and/or carbonate. In the first step, the crude phosphoric acids and the alkali metal hydroxide and/or carbonate are mixed together so as to produce a mixture with a pH-value of between 4 and 9, and resulting primary sludge consisting substantially of insoluble aluminum and iron phosphates is isolated from the purified phosphate solution. In the second step the sludge is mixed with a mixture consisting of alkali liquor (i.e. alkali metal hydroxide solution) and a trialkali phosphate solution and with a mixture consisting of water glass and a trialkali phosphate solution so as to produce a mash containing SiO2 and Al2O3 in a molar ratio of larger than 2:1, and dissolved alkali metal oxide and dissolved P2O5 in a molar ratio of between 2.9:1 and 3.3:1. In the third step the second step mash is heated to temperatures of between 80 DEG and 100 DEG C and sludge appearing in the mash is disintegrated. This results in the formation firstly of a solution and secondly of a solid residue which is isolated and discarded. In the fourth step, the third step solution containing between 0.1 and 1.0 weight percent fluorine, is cooled to effect crystallization of a trialkali phosphate/alkali fluoride double salt, which is isolated from its mother liquor, and successively used for purifying a portion of the crude phosphoric acid with the resultant formation firstly of a secondary neutralization sludge, which is discarded, and secondly of a purified alkali phosphate solution, which is combined with alkali phosphate solution purified in the first step.
