Patent ES-463527-A1 (ES)
Title: Epoxidation
IPC: C07D301/16
Filed: 1977-10-25
Abstract: Epoxidation of an alkene by reaction with a peroxycarboxylic acid to produce an oxirane. A peroxycarboxylic acid in organic solution is reacted with an alkene to produce a product mixture. Unreacted alkene is separated from the product mixture as a gas. The separated alkene is absorbed into the organic solution containing the peroxycarboxylic acid. The oxirane product is obtained by purification of the product mixture after the alkene has been separated. The organic solution containing the peroxycarboxylic acid is preferably obtained by countercurrently contacting an aqueous phase which includes sulfuric acid, hydrogen peroxide and water and an organic phase containing carboxylic acid and organic solvent.
Patent ES-465151-A1 (ES)
Title: Method and apparatus for eroding inner and outer walls of work pieces
IPC: B23H7/28
Filed: 1977-12-16
Abstract: A method and apparatus for eroding inner and outer walls of work pieces, such as cylinders and cones, by electrical discharge between the work piece and an electrode are described wherein an electrode-holder is mounted for variable orbital movement on a hollow support fixed on a cylinder axially movable by fluid pressure with respect to a piston therein, along an axis perpendicular to the plane of the orbital movement. A normally fixed piston rod carries the piston, and a shaft extends through the piston rod from the interior of the support to means, providing for coarse and fine adjustment, fixing the shaft to the rod. A rotor in the support is rotatable on the shaft and has an inclined track with which an inclined track on a cam unit is in sliding engagement. The cam unit is rotated on the electrode-holder by power means supported thereby and the cam unit rotates on an axis parallel to the shaft and which orbits about the shaft at a radius depending on the relative position of the two cam tracks which orbit with the electrode-holder. Alteration of the orbit radius or eccentricity is effected either by adjustment of the shaft in the piston rod or by axial movement of the cylinder which is limited in each direction by stops. In the event of excessive pressure arising in the cylinder the piston rod can yield axially against resilient restraint.

Patent ES-483567-A1 (ES)
Title: Frequency chirp in isotopically selective photoexcitation
IPC: B01D59/34
Filed: 1979-08-22
Abstract: Method and apparatus for inducing isotopically selective photoexcitation of atoms in at least first and second energy steps. The total energy change accomplished by the two energy steps is provided with isotopic selectivity at precise resonance for the two steps. In an isotope separation system in which an environment of particles of plural isotope types is created, isotopically selective photoexcitation from laser radiation is shown to produce a great improvement in excitation efficiency where the radiation is controlled in the aggregate of plural photons to achieve precise resonance over the plurality of the degenerate energy steps. Even with multimode excitation, precise resonance is only achieved for isolated atoms, and a chirp or frequency sweep is applied to one of several excitation frequencies to insure precise resonance at least once for each atom. In the case of excitation in plural transitions from plural low-lying energy through a generally common upper transition, the chirp may be applied to the radiation producing the common upper level transition alone.

Patent ES-8308610-A1 (ES)
Title: Security installation to protect against robberies (hold- ups) for banking and similar institutions
IPC: E05G5/00
Filed: 1982-11-24
Abstract: An installation which consists of a series of devices which, from a selected control point, are brought into an operating condition, which results in all the cash and other valuables and objects located on the counter of the cashier or cashiers being immediately and automatically slid, by means of tilting and/or opening of the counter, into a receiving deposit which may be a metal box which is in the lower part of the counter which, in turn, once it has received the valuables and objects, is also automatically taken by a suitable mechanism to an armoured housing from which it cannot be removed. The mechanism is self-locking, i.e. once its transition to the operating condition has been initiated, it cannot be stopped or reversed in its movement thanks to the existence of a ratchet device, hidden behind a second armoured housing, to which it is possible to gain access, in order to unlock it, only after a series of metal covers provided with the greatest possible number of screws has been removed, so that an excessively long period of time is taken in order to be able to remove them. In this way, it is not possible to coerce the bank staff to use keys and/or combinations to open the housing where the armoured housing which contains them is located. The installation is also provided with means which allow normal operation of the counters and drawers in their non-operational condition. Selectively, the system may also include an extension capable of sliding an inner door in the vault of the bank or the like, such that, although the manager or another official is obliged to use the combination in order to open the door of the vault, the second door, which bears the respective self- locking mechanism, prevents passage to the interior of the vault. Naturally, the ratchet and the unlocking means are located behind screwed-down covers or casings identical to those provided on the counters, for the same purpose.
