Patent ES-376161-A1 (ES)
Title: Slide valve for high-viscosity pumps
IPC: F04B15/02
Filed: 1970-02-03
Abstract: A slide valve for dense or viscous materials, e.g. concrete, has a slide element connected to a piston rod which extends out of the valve housing through a seal and carries a piston received in a cylinder which is clamped to the housing around the seal by a clamping nut. The cylinder has an outer actuation chamber while an inner annular chamber between the piston and the seal is a flushing compartment connected to a reservoir of liquid through a single duct. As the piston moves toward the seal, the liquid in the flushing compartment is expelled, taking with it any foreign matter which has gotten past the seal, and as the piston movement is reversed this compartment is filled with the liquid via this duct to flush the rod again. The valve element, valve guides, end stops, and sleeves surrounding the piston rods are all easily removable and replaceable to facilitate servicing of the valve.

Patent ES-463128-A1 (ES)
Title: Wideband electromechanical recording system
IPC: G11B3/00
Filed: 1977-10-11
Abstract: A system for recording signals in a disc master comprises an electromechanical cutterhead responsive to the signals and a signal processing means interposed between the cutterhead and a signal source. The signals applied to the cutterhead are of the encoded type such that most of the signal energy is contained in signal components occupying a band of frequencies about one octave wide or less. The cutterhead is so constructed that its response to the signal components varies with frequency in substantial correspondence with the energy distribution of the maximum signal components over the afore-mentioned band. The signal processing means serves dual purposes. On the one hand, it cooperates with the cutterhead to provide a combined frequency response which is relatively uniform. On the other hand, it serves to reduce the energy level of high energy level signal components applied to the cutterhead. The reduction of the applied energy makes possible the use of a smaller cutterhead than would otherwise be the case. The smaller cutterhead structure, in turn, results in a relatively wide cutterhead bandwidth.

Patent ES-469523-A1 (ES)
Title: Improvements in the mechanical process for obtaining artichoke hearts.
IPC: A23N/
Filed: 1978-05-05
Abstract: The process consists of combining in a continuous cycle a series of progressive and simultaneous mechanical operations, through the rotation of a stand on which the artichokes are placed in positions facing the mechanical devices through which an artichoke undergoes the following operations: a transverse cut above the height of the base of the heart, to remove the leaves; a peripheral cut determined by the peripheral diameter of the base, at the same time as it is cleaned to remove the choke; bevelling at the bottom to form the external cone of the heart and a cut below to separate it from the stalk. Finally, in a subsequent phase, the stalk is removed from the stand. All the abovementioned operations are performed using as a general support for the artichokes a vertical plate to subject them to the various phases described above in a continuous cycle, as a movement on its horizontal axis, involving a series of individual supports for the artichokes at equidistant positions, the rotational movement of the plate being timed, so that in each of the rotations of the vertical plate, the artichoke is positioned facing a tool, supported statically, on a stand with advance movement over the artichoke.
Patent ES-476080-A1 (ES)
Title: Method for molding optical plastic lenses of the standard and bifocal type
IPC: B29C61/00
Filed: 1978-12-16
Abstract: A bifocal lens is produced on either a previously formed blank lens, or completely in a singular casting between two molds. The bifocular lens is obtained by supporting a bifocal lower mold having a recessed bifocal well area on itsconcave surface and filling the lower mold with a resin material. By positioning an upper mold in vertically spaced relationship to the lower mold, the resin material is displaced to extend between the overlapping surfaces of the molds to form the configuration of the bifocal lens with a bifocular portion on the convex lens surface corresponding to the bifocal well on the lower mold. Curing of the resin material situated between the molds and cooling the resin material and the molds forms the complete lens. Thereafter a separating of the bifocal lens from between the molds leaves the bifocal lens in a position to be completed and installed in a pair of eye glasses. Single vision ophthalmic lenses are similarly produced by means of the aforedescribed method.

Title: Spring assemblies for mattresses
IPC: A47C27/07
Filed: 1979-07-10
Abstract: A spring assembly for a mattress includes a plurality of spiral coil springs (16), arranged in substantially parallel rows, a plurality of cross helicals (22) lacing together adjacent springs in the same row, adjacent coil springs with laced-together terminal convolutions (20) being restricted in their movement relative each other to a maximum angle of deflection. The convolutions (20) of adjacent springs have offset portions (24) with overlying alternating projections (30, 32) which permit a hinging action of the adjacent springs relative to each other about the adjacent offset portions of their terminal convolutions, until the maximum deflection angle between the offsets is reached. Further loading of one spring after this angle is reached results in compression of adjacent springs and greater resistance to loading for a given degree of spring compression, i.e. greater firmness.
