Patent ES-382205-A1 (ES)
Title: High speed mixing impeller
IPC: B01F15/00
Filed: 1970-07-27
Abstract: Stirrer has a supporting disc from which vanes project outwardly. The vanes are shaped to extend in the circumferential direction, and adjacent vanes overlap. The vanes may be pivotally mounted, (as shown) and may be adjusted by relative rotation of the supporting disc and a central gear meshing with gear sectors on the vanes. The central gear may normally be clamped to the supporting disc, so that adjustment is effected with the stirrer stationary after releasing the clamp, or the supporting disc and central gear may be fixed to concentric shafts to allow adjustment during rotation. The width of the outer surface of each vane is dependent in the length of the vane, that is, a shorter vane should be wider than a longer vane, in inverse proportion to the length. A groove may be formed along the centre of the outer surface.

Title: Process for providing bearing surfaces on trunnions of a universal joint
IPC: F16C11/08
Filed: 1974-05-24
Abstract: To produce on at least one of the end faces of opposed trunnions of the cross member of a universal joint a bearing surface for the end wall of a bearing cup, or for a resilient washer interposed between the cup end wall and the trunnion, there is chosen for the distance between the centre of the cross member and the centre region of the end face a value which is different from the value of the desired distance in joint operation. This centre region is then subjected to the action of a tool whose hardness exceeds that of the metal of the trunnion by causing the tool to travel such distance that the active surface of the tool occupies a position in which there is formed, by a cold upsetting of the metal, a centre bearing surface which is at a distance from a reference point, such as the centre of the cross member, which is substantially equal to the desired value of the distance in joint operation.

Title: Closed cycle apparatus for the rapid, continuous and waterless dyeing of textile and plastic materials
IPC: C08J7/12
Filed: 1977-08-10
Abstract: The present invention relates to a closed cycle apparatus for the rapid, continuous and waterless dyeing of a textile or plastic material with a dyestuff dissolved or suspended or dispersed in a high boiling solvent (such as glycol or glycol ether or other members of the alcohol family) for carrying out the dyeing step, after which the dyed textile or plastic material subsequent to cooling is washed with a low boiling liquid (such as methanol or ethanol) and then dried. The apparatus is constructed so as to operate under non-aqueous or substantially non-aqueous conditions with the complete or substantially complete recovery and recycling of the used dyestuff, the used high boiling solvent and the used low boiling wash liquid. In this way, the apparatus can be operated at a relatively low cost and in a completely or substantially completely closed cyclic system with essentially complete recovery and reuse of the treating fluids so as to greatly minimize the cost of operating the dyeing apparatus and also without any pollution of our natural water resources. Pollution of many of our rivers and wells has taken place in the past where effluents of a substantially aqueous nature containing serious amounts of polluting substances were discharged into rivers and the like thereby creating environmental problems.
