Title: Air pressure operated braking systems
IPC: B60T8/18
Filed: 1967-10-25
Abstract: In an air pressure operated braking system for a motor vehicle fitted with air suspension incorporating a light/laden control valve 1 of the type described in Specification 1,077,954, actuated through a lever 6 by a control cylinder 8 responsive to pressure in the air suspension system, an additional cylinder 14 is provided which is responsive to the reservoir pressure and which is also connected to the lever 6.

Patent ES-380305-A1 (ES)
Title: Rotary piston engine
IPC: F01C1/10
Filed: 1970-06-02
Abstract: The invention relates to a rotary piston engine of the type having an internally toothed ring and an externally toothed wheel which is orbitably and rotatably movable relative to the ring. The motor has a disk shaped valve which is driven by the externally toothed wheel through a universal joint shaft. In order that the shaft only applies torque to the valve, to the exclusion of any axially directed force, the valve has a splined bore and is journalled on a cylindrically shaped abutment which is fixed relative to the casing. The shaft has a splined head which engages the splined bore of the valve to effect rotation of the valve but the shaft head is in axial thrust engagement with the abutment so that no axial forces are transmitted to the valve. The valve and casing parts are appropriately and uniquely disigned with cooperating annular recesses so that axially directed hydraulic forces on the valve are also minimized. The overall result is that there is no mechanical axial loading of the valve and little or no hydraulic axial loading of the valve.

Patent ES-397774-A1 (ES)
Title: Roll winding machine
IPC: B65H18/14
Filed: 1971-12-07
Abstract: An apparatus for winding paper or the like onto two shafts driven by a rotating cylinder which they contact at diametrically opposite locations. The shafts are urged at their ends toward and into contact with the cylinder. Intermediate the ends of each shaft, a pair of rollers rotatably mounted on a frame articulated to a pivot arm urge said shaft toward the cylinder to make certain of uniform contact along the length of the shaft so as to prevent bowing and wrinkling. The pivotal mounting of the arm permits displacement as the package builds up. After the package is large enough so that the paper reinforces the shaft and itself ensures uniform contact without bowing, the pivot arm is moved to inoperative position where the rollers no longer act on the shaft.

Title: Method and apparatus for pneumatically removing fiber and trash waste on open-end spinning machines
IPC: D01H4/36
Filed: 1977-01-12
Abstract: A method and apparatus of spinning yarns on an open-end spinning machine having a plurality of spinning positions, in which trash waste separated from the fibers of the slivers during advancement through respective fiber opening zones to respective yarn spinning rotors is continuously removed from the opening zones by a low velocity suction current of air and pneumatically conveyed along respective passageways to a central waste collection zone.

Patent ES-463817-A1 (ES)
Title: Sea platforms to support industrial installations
IPC: E02B17/00
Filed: 1977-11-03
Abstract: A marine platform supports industrial installations. The platform comprises a barge and a lower keel on which the barge rests. The keel is positioned on the ocean floor. Intermediate friction elements are situated between the contact surfaces of the barge and the keel. Elastic elements are interconnected to the barge and the keel. These elastic elements oppose displacements between the barge and the keel. The displacements are controlled because the friction resulting from the intermediate friction elements impedes movements between the barge and the keel. These movements may be caused by external forces acting on the barge, such as waves, currents, and winds, or may be caused by the effects of acceleration on the keel induced by an earthquake of small magnitude. The intermediate friction elements have means for permitting displacements between the barge and the keel in the case of an earthquake of great magnitude. The elastic elements have means for decreasing an elasticity constant in discrete degrees when the displacements surpass a predetermined value so that, as the intensity of the earthquake increases, the oscillation period of the barge on the keel increases too but amplication of the oscillation period is avoided.
