Patent ES-338895-A1 (ES)
Title: Abrading device or file
IPC: A45D29/04
Filed: 1967-04-04
Abstract: A metal foil 1 securable to a backing member 2 to form a file has tooth ridges, la separated by smooth concave recesses 1c the tooth .ridges terminating .in a common, working plane and having faces which lie at approximately 90 to this plane. The tooth ridges may have smooth crown surfaces 1b preferably at least 10 microns in width but alternatively the faces of the tooth ridges may meet substanially in a point Id, Fig. 9. The teeth may be straight and parallel or curved and may lie in intersecting directions. (Fig. 8 not shown). The foil may be cemented back to back with a similar foil or to a disc or cylindnical member to form a nail file or a tool for filing plastics or metal which is stated to have a polishing effect in use. To produce the foil a negative former is first prepared by printing, photographically or otherwise, a pattern of non-conductive regions 3a on a metal plate 3. Metal is then deposited electrolytically or by means of a salt bath on the conductive regions to form a series of projections 3b which are allowed to grow till the desired spacing for the tooth ridges exists between the projections. The entire former is then coated with a conductive separating layer and metal preferably nickel, deposited electrolytically or by a salt bath to form the foil which can subsequently be removed from the former. The deposition of the metal of the foil may be initially by a salt bath method to produce a hard surface layer and subsequently by an electrolytic method to provide a backing layer of the same or different metal.

Patent ES-395948-A1 (ES)
Title: Gauge control method and apparatus for metal rolling mills
IPC: B21B37/16
Filed: 1971-10-13
Abstract: A programmed computer control system provides an on-line roll force gauge control for a multiple stand tandem hot metal strip rolling mill. A gauge control program calculates the workpiece strip delivery gauge error from at least one stand of the rolling mill and from this gauge error determines a required roll opening correction to remove this gauge error. The gauge control program then determines in relation to the magnitude of the delivery gauge error and related roll opening correction for the same one stand that this delivery gauge error is to be corrected by adjustment of the roll opening of that same one stand or is to be fed forward in the direction of the workpiece strip movement for correction in a succeeding stand of the rolling mill by adjustment of the roll opening of the succeeding stand. The roll opening correction is effective to adjust the latter stand operation for a time interval related to the movement of the workpiece strip increment from the stand where the gauge error is measured to the following correction stand of the rolling mill, assuming the latter stands are adjacent stands of the rolling mill.
Patent ES-400895-A1 (ES)
Title: Packing for compressors, pumps or the like
IPC: F04B39/04
Filed: 1972-03-17
Abstract: The improved packing rings described in detail hereinafter provide an integrally formed, internally located check valve for use in the lubrication systems compressors, pumps or the like. Specifically, and in the preferred form, two adjacent packing rings include face portions arranged in sealing engagement with at least one of the packing rings a lubricant passageway therein. An arcuate groove is formed in the face of one of the packing rings in communication with the lubricant passageway. One of the packing rings includes a pressure-responsive, integrally formed annular lip that encompasses the arcuate groove. The arrangement is such that a predetermined pressure in the lubricant groove moves the lip away from the adjacent packing ring permitting lubricant to pass out of the arcuate groove into the interior of the compressor. During the compression stroke of the compressor, the high pressure existing inside the compressor acts on the pressure responsive lip forcing it into tighter sealing engagement with the adjacent packing ring preventing the compressor pressure from entering the lubrication system.

The second sealing ring has a frustoconical face closely adjacent the first face portion and bounds therewith a narrow passage extending obliquely from an inner orifice near the afore-mentioned smaller base to an outer orifice adjacent the larger base of the first face portion. The two sealing rings are fastened to the two bodies so that they rotate relative to each other during operation of the bearing.

Title: Control lever system, particularly for vehicle brakes
IPC: B60T7/04
