Patent ES-361890-A1 (ES)
Title: Process for the production of the dinitrogen tetroxide
IPC: C01B21/36
Filed: 1968-12-27
Abstract: The production of dinitrogen tetroxide by the combustion of air with ammonia in the presence of a catalyst, oxidation of the resulting gas mixture of NO and NO 2 at an elevated temperature with nitric acid and subsequent isolation of N 2 O 4 by compression of the gas mixture and cooling, is improved by carrying out the compression to a pressure of at least 4 atmospheres and cooling to not less than 8 C., after which part of the NO 2 is withdrawn as liquid N 2 O 4 , the oxygen content of the gas mixture is supplemented with air at least stoichiometrically sufficient for the formation of N 2 O 5 from NO 2 and the resulting mixture treated with nitric acid from the oxidation step until a nitric acid of concentration 55-70% by weight is obtained at least part of which is recycled to the oxidation stage. The residue NO in the gas mixture after compression but before cooling is removed by allowing it to continue to react in the presence of air added before the compression. When the process is carried out continuously the water which accumulates is removed as nitric acid during the oxidation of NO, the removed acid having a concentration between that of the concentrated nitric acid employed and the dilute nitric acid arising after the oxidation.

Title: Pulse width sensing circuit
IPC: H03M5/08
Filed: 1974-03-16
Abstract: A circuit for producing an output signal indicative of the presence of an input signal of duration greater than a given duration, T. The circuit includes a first stage which in response to a sampling pulse and the presence of an input signal of first value, stores a signal of first binary significance. The circuit also includes a second stage which in response to a shift pulse occurring a time T after the sampling pulse produces at its output, which is the circuit output, a signal corresponding to the one stored in said first stage. Each stage includes means responsive to the input signal for resetting the output of each stage to a level of second binary significance when the input signal has a second value. A signal of first value must, therefore, be present for a duration greater than T to produce an output of first binary significance, where the duration must also include a sampling pulse followed by a shift pulse. The circuit also includes means for, selectively, directly passing the input signals from the input to the output of the circuit.

Patent ES-443286-A1 (ES)
Title: Method and apparatus for separating material
IPC: B03C1/029
Filed: 1975-12-06
Abstract: A method for magnetic separation of materials wherein the materials are ground to provide a mixture of fine particles of more- and less-magnetic materials which may include paramagnetic material and diamagnetic material. Discrete bodies of highly magnetizable material are introduced to a magnetic field of high intensity and thereby become a closely consolidated mass of bodies having interstitial pores extended through the mass in all directions. The mixed particles are caused to flow through the pores and the less-magnetic particles are separated from the more-magnetic particles and the mass of bodies in the magnetic field. The more-magnetic particles are separated from the bodies by moving the mass of bodies out of the magnetic field and by demagnetizing them so that they tumble freely and by washing or otherwise removing the particles from the bodies as they tumble after leaving the closely consolidated mass.

Patent ES-458406-A1 (ES)
Title: Electric device provided with a switch which is designed as a discharge tube
IPC: H01J17/22
Filed: 1977-05-03
Abstract: The invention relates to an electric device provided with a switch which is constructed as a discharge tube which comprises at least two main electrodes and a reversible hydrogen getter. According to the invention the discharge tube contains a rare gas so that the current flow in the conducting state of the switch is mainly ensured by that rare gas. The non-conducting stage of the switch can be obtained by heating the getter. Namely, the hydrogen pressure in the discharge tube then becomes so high that the discharge in the tube is extinguished. Heating of the getter is preferably effected by the heat developed by the current between the main electrodes. This results in a self extinguishing breakdown element.

Title: Method for the production of a layer capacitor
IPC: H01G4/30
Filed: 1977-09-23
Abstract: A simplified and less expensive method for producing layer capacitors is disclosed in which an output capacitor is produced by winding several master or parent capacitors on a drum one upon the other.

These separating films are then cemented to one another and to one of the parent capacitors lying underneath, but not to the parent capacitor lying above. Protruding portions of the separating layers are ground off. The portions of the separating layers remaining serve as protecting covering layers after the separation of the parent capacitors from one another.

Title: Pressure regulator for a fluid pump
IPC: F02M63/00
Filed: 1977-12-29
Abstract: A centrifugal pressure regulator comprises a pair of pistons slidable within a bore and moves in one direction by the action of a coiled spring and by centrifugal force imparted to the pistons as the body in which the bore is located rotates. The outer ends of the two pistons are subjected to the outlet pressure of a pump and the piston adjacent the spring is smaller in diameter than the other piston. The space between the pistons is vented to a drain and in the wall of the bore there is formed a spill port. The smaller of the pistons controls the size of the port which communicates with the outlet of the pump. The outlet pressure of the pump is controlled in accordance with the position of the pistons by spilling fuel through the port, the amount of fuel spilt depending on the effective size of the port.

Title: Method of forming a socket end on a plastic pipe and a molding device for use of the method
IPC: B29C57/02
Filed: 1979-10-02
Abstract: For the purpose of making a joint socket comprising at least two portions, namely a portion for receiving a plastic pipe end and another portion into which a rubber ring is fitted, a method of heating and softening a plastic pipe end and enlarging the radius of the softened pipe end to twice its size which includes, an inwardly slanted portion between a first outwardly slanted portion and a second outwardly slanted portion whose radius becomes smaller as it comes nearer to the front end thereof. As the result, the frictional resistance between an improved core and the radius enlarged softened pipe is reduced to a value which enables the method to be carried out such that wall-thickened sockets can be made without loss of wall thickness subsequent to the radius enlarging process. The core for forming a molding space includes the first outwardly slanted portion, the inwardly slanted portion and the second outwardly slanted portion and which are necessary to perform the method can be expanded and shrunk so as to pass through the small and large radius portions of the molded socket and has a self-locking mechanism capable of resisting the resistance caused between the forcedly fed pipe and the core.
