Patent ES-367702-A1 (ES)
Title: Lifting magnet for sheet-formed objects of magnetisable material
IPC: H01F7/20
Filed: 1969-05-14
Abstract: A lifting electromagnet comprises two magnet coils carried in a yoke having a flat underside with annular polepieces and including an intermediate pole, common to the magnetic circuits of both coils, located between the coils and means being provided for reversing the current in one of the coils. As shown, Fig. 1, the magnet comprises two coils 1, 2 arranged to be independently energized and mounted in a yoke 3 which provides an inner polepiece 5, an outer polepiece 6, and an intermediate polepiece 7 having a magnetic cross-section of approximately one quarter that at each of the inner and outer polepieces. When the coils are energized in the same direction, Fig. 5 (not shown), a large lifting force is provided, the magnetic lines of force passing directly between the outer and inner poles through the load, the field in the intermediate pole being substantially zero. When the coils are energized in opposite directions, the magnetic lines of force pass through the load from both the inner and outer poles to the intermediate pole, the lifting force is reduced and the penetration of the magnetic field into the load is greatly reduced. The magnet may be used to lift a stack of steel sheets or to lift a single sheet from a stack by energizing the coils in the same or in opposite directions respectively.

Patent ES-418709-A1 (ES)
Title: Ignition system dependent upon engine speed
IPC: F02P3/045
Filed: 1973-09-12
Abstract: An internal combustion engine is comprised of at least one engine cylinder, devices for introducing a combustion mixture into the cylinder, and an electrical igniting element operative for igniting the combustion mixture in the cylinder once per ignition cycle. An ignition transformer has a secondary winding connected across the igniting element, and also has a primary winding. A flow of current is established through the primary winding. An electronic switch is connected in the current path of the primary winding to control the flow of current through the primary winding. A triggering unit generates a train of crankshaft-synchronized triggering signals. A monostable control circuit has a trigger input for receipt of such triggering signals, and is operative when triggered into the unstable state for rendering and maintaining the electronic switch non-conductive for the duration of the unstable state, so as to interrupt the flow of current through the primary winding and induce across the secondary winding a voltage surge causing the igniting element to ignite the combustion mixture in the engine cylinder. When the monostable control circuit reverts to its stable state, it renders and maintains the electronic switch conductive for the duration of the stable state, whereby to establish a build-up of current flow in the primary winding in preparation for the next interruption of current flow. The monostable control circuit includes a timing stage operative for automatically increasing the ratio of the duration of the unstable state to the duration of the ignition cycle with increasing engine speed within a predetermined range of engine speeds.

Title: Process for generating movement and energy on the basis of the flotation of bodies
IPC: F03B17/02
Filed: 1977-08-25
Abstract: The present invention relates to a process for generating movement and energy on the basis of the flotation of bodies, being based on the use of a receptacle provided with a valve for intake and a valve for expulsion of a determined liquid, preferably water, there being situated in the interior of the receptacles a hollow body or a body filled with a material whose density is lower than that of the said liquid but with the special feature that the distance between the two lateral contours of the receptacle and the interior body referred to is minimal and this is for the purpose that the volume of liquid necessary to cause the floating of the said interior body is also minimal, therefore, depending on the variable volume of liquid circulating through the receptacle, thanks to the said intake and expulsion valves, the floating body effects an ascending-descending movement which, by means of conventional elements interposed, is used to transform the said alternating movement into a circular movement or into any other that is deemed pertinent, to activate mechanisms of the most diverse complexity, including those intended to generate and store electric energy. It should be stated that various elements the same as or similar to that detailed may be arranged in battery form in order to act jointly or separately, with the specification that the alternating opening of the valves for the intake and expulsion of liquid into and out of the receptacles, as well as the closing of the said valves is automatically effected when the level of the liquid or that of the floating body incides on conventional electronic devices provided for the purpose.

Abstract: A system for manufacturing chopped strands of glass filaments wherein a multiplicity of glass filaments are extruded through orifices in the bottom of at least two spinning furnaces and a sizing agent is applied and the filaments are collected to form at least two strands. The strands brought into contact with the circumferential surface of a feed roller through a predetermined angle so as to be drawn and attenuated by frictional force exerted by the circumferential surface of the feed roller while the strands are cut into chopped strands of a predetermined length with a cutter roller in contact with the feed roller. An auxiliary feed roller is disposed adjacent to one end portion of and in axial alignment with the main feed roller and is driven independently thereof. An auxiliary cutter roller is adapted to contact under pressure the circumferential surface of the auxiliary feed roller to rotate therewith.
