Patent ES-467907-A1 (ES)
Title: Oil tankers with segregated ballast tanks
IPC: B63B11/02
Filed: 1978-03-16
Abstract: An oil tanker is provided with segregated ballast tanks in the form of tanks (41) within the vessel's hull and one or more tanks (43) welded to the vessel's upper deck.

Title: Process and apparatus for manufacturing radial tires
IPC: B29D30/36
Filed: 1979-10-25
Abstract: A process is provided for manufacturing radial tires for a motor vehicle having a radial carcass, a reinforcing structure with at least two layers of criss-crossed symmetrically arranged metallic cords forming a belt, and a tread.

A reinforcing belt is also formed by winding two layers of metallic cords on an auxiliary expandable drum with a diameter equal to the external diameter of the toroidal shaped carcass. The belt is maintained in slidable contact on the drum and shaped toroidally by expanding the auxiliary drum. The belt is then removed from the auxiliary drum and transferred with a tread band to the carcass on the first drum. The carcass is toroidal shaped again to assemble the carcass and belt. The assembly is vulcanized under pressure in a mold.

Title: Process for the superficial treatment of a non-woven and very aerated fibrous filter layer forming an electret, and its application to filters and especially respiratory masks.
IPC: D04H1/54
Filed: 1981-04-15
Abstract: The process of the invention consists in smoothing the or each fluffy surface of the layer by exerting a slight friction under low pressure so that the projecting fibers are flattened on the subjacent fibrous mass without the latter being compressed, the friction being exerted at a softening temperature such that the superficial fibers are welded together to form a skin or porous glaze. The smoothing is preferably effected by means of a metal mass whose temperature is between 115 DEG and 150 DEG C. This process may be applied to the outer face of a filtering breathing mask constituted by an envelope made of this fibrous material covering a relatively rigid porous shell for protection of the skin it may also be applied to at least one of the faces of filtering layers equipping filters of any type.

Title: Walking doll
IPC: A63H7/04
Filed: 1981-10-27
Abstract: A walking doll is described having a pair of side by side legs which automatically pivot forwardly when lifted off the ground. The legs include movable, side by side buttocks.
