Patent ES-363474-A1 (ES)
Title: Improvements in and relating to an Electric Contact Arrangement
IPC: H01H1/36
Filed: 1969-02-10
Abstract: An electric contact arrangement comprises a first contact 1, 2 and a second contact 4 mounted for relative rectilinear sliding movement, one of the mutually engaging surfaces of the contacts being convex and the other being concave, the radius of curvature of the convex surface being less than that of the concave surface, the arrangement being such that the convex surface is cleared by the leading edge 6, 7 of the concave surface during sliding movement of the edge 6, 7 on the convex surface. During part of its sliding movement contact 4 engages both fixed contacts 1, 2 or there may be an insulating member between contacts 1, 2 to prevent contact 4 engaging both contacts 1, 2 simultaneously.
Patent ES-370072-A1 (ES)
Title: Restriction device for an antilock brake system
IPC: B60T8/40
Filed: 1969-07-30
Abstract: An anti-lock brake system for a wheeled vehicle includes a fluid pressure line for connection from a fluid pressure source to a wheel brake controlled by the system, an elongate slide member arranged for longitudinal movement into a section of the line, which member is so dimensioned as to provide between itself and the inner wall of the section a clearance which forms a restricted fluid path in the section, and means for varying the extent of penetration of the slide member into the section during operation of the system to cause variation of the length of the fluid path and thus of the restriction afforded by it. As shown in Fig. 4, when a valve VI is opened by an actuator responding to wheel speed reduction, fluid is able to flow from the brake line W to a reservoir chamber C. Piston P1 in the reservoir is thereby moved to the right against spring S, and slide R1 forming an extension of the piston causes further restriction of the path from the master cylinder to the brake line. The increase in restriction is a function of degree of filling of the reservoir. Optionally a second restrictor slide R2 extending from the other side of the piston operates in the line from the reservoir to the scavenging pump Ps so as to be effective just when the tip of R1 is beginning to uncover the inlet port, to act as a temporary check to scavenging. In Fig. 6 (not shown), the spring S (which is not essential), is omitted. Fig. 5 (not shown), is analogous to Fig. 4, but the scavenging pump and master cylinder are replaced by a high-pressure pump, a pressure reservoir and a brake-pressure control, in series. Fig. 7 resembles Fig. 4, but the spring S is replaced by a smaller piston P2 linked to piston P1. Fig. 8 is a practical embodiment of Fig. 7, where face A corresponds to piston P2 and face B to piston P1.

Patent ES-385049-A1 (ES)
Title: Ignition arrangement for internal combustion engines
IPC: F02P1/08
Filed: 1970-10-30
Abstract: Four rotating magnets, driven by the engine, induce in two or more windings a charging pulse, a discharging pulse, and a control pulse, the latter pulse in certain embodiments being identical with the charging pulse. The control pulse, the value of which is engine rpm-dependent, causes a normally open circuit shunting the ignition capacitor to close when the engine rpm exceeds the permissible maximum, thereby discharging the ignition capacitor and preventing it from furnishing electrical energy to the spark coil. In this way, the engine rpm is limited to safe values.

Patent ES-410400-A1 (ES)
Title: Magnetic beam adjusting arrangements
IPC: H04N9/28
Filed: 1973-01-05
Abstract: A pair of four-pole magnet rings, each mounted for independent, concentric rotational adjustment about the neck of an in-line, tri-beam shadow-mask color kinescope, constitute a facility for introducing mutually opposing shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central, axial beam, and without requiring internal pole piece structures for field directing purposes. A pair of 6-pole magnet rings, each mounted for independent, concentric rotational adjustment about an adjacent region of the color kinescope neck, constitute an additional facility for introducing like-direction shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central beam, and without requiring internal pole piece structures for field directing purposes. The two magnet ring pairs together provide an arrangement for effecting static convergence of the beam trio at the kinescope screen. A third pair of two-pole magnet rings, similarly subject to rotational adjustment about the kinescope neck, provide means for introducing like-direction shifts of all three beams in any desired direction for conventional purity adjustment purposes. In a preferred application of the invention, the two-pole ring pair, six-pole ring pair and four-pole ring pair, appear in axially spaced relation of a common mount surrounding the kinescope neck to the rear of a deflection yoke (with the ring pairs in the order named, progressing from the neck base toward the yoke rear) and constitute the only neck components (exclusive of the deflection yoke) required in set-up and operation of the color kinescope.

Title: Machine for printing on cylindrical or frusto-conical containers with ultra-violet-light-setting ink
IPC: B41F17/22
Filed: 1974-12-20
Abstract: A machine for printing on containers in ultra-violet-light-setting ink has a turret fitted with rotatable mandrels for supporting the containers, the axes of the mandrels being radial relative to the axis of the turret, indexing mechanism for intermittently turning the turret to register each mandrel in succession with printing cylinders spaced around the turret, and gear unit for rotating the mandrels and printing cylinders in synchronism. The turret has a cylindrical rim with flat annular upper and lower surfaces, and each mandrel is mounted in a recess in the rim with the recess opening through the lower surface to permit engagement with the printing cylinders and opening through the periphery of the rim to enable containers to be mounted on the mandrels. Ultra-violet light sources are arranged to direct light into the recesses to set ink printed on containers on the mandrels, and the light sources are provided with shrouds which co-operate with the rim to prevent escape of the ultra violet light except into a recess. The light sources may be fixed in which case the shrouds are spaced close to the surfaces of the rim. Alternatively, the light sources and shrouds may be fixed on the turret. The printing cylinders are twice the diameter of the containers and fitted with a printing plate which extends only half way around the cylinder, the surface of the cylinder being spaced below the lower surface of the turret rim, the printing plate having a thickness such that it extends into the recess during printing, and the indexing mechanism being synchronised with rotation of the cylinders so that the printing plate is on the underside of the cylinder during indexing movements of the turret. The recesses may open through the upper surface of the turret rim and a light source arranged to direct light downwards onto a container while the container is being printed through the opening in the lower surface of the rim, so that the ink on the leading edge of an image printed on the container will be cured before the trailing edge is printed, whereby the trailing edge can overprint the leading edge without risk of smudging the ink.

Patent ES-450162-A1 (ES)
Title: Centrifuge separation and washing device and method
IPC: B04B5/04
Filed: 1976-07-26
Abstract: A centrifuge device and method are provided for separating and/or washing finely-divided solid particulate material suspended in a liquid. The invention is especially useful in so treating blood. The centrifuge forms a dense suspension of blood cells in a plurality of blood cells receiving means evenly spaced about the periphery of a rotatable enclosure. The receiving means have converging walls which at their juncture form a locus of maximum centrifugal force. Wash liquid is passed through the dense suspension of blood cells counter to the direction of the centrifugal force by entry into the blood cell receiving means at the locus of maximum centrifugal force. Independent conduits connect the locus of maximum centrifugal force through an injector to a supply for the wash liquid and, after fully resuspending the blood cells in a suitable resuspending liquid, the resuspended cells exit from the centrifuge via the independent conduits and injector, which have also therefore been washed by the wash liquid. Thus recontamination is avoided. A unitary disposable structure including the enclosure, blood cell receiving means, conduits and injector is also provided.
