Abstract: The present disclosure comprises a new method for hydrothermal synthesis of ferrierite zeolite, using tetramethylammonium and benzylmethylpyrrodlidine as directional structure agents, and does not require a subsequent process in order to obtain the acid form of the material. This aspect is very important as it avoids subject treatments of calcination and successive interchanges which degrade the structure of the zeolite. The synthetic ferrierite obtained by means disclosed processes has uses in catalytic processes of transformation of hydrocarbons, such as cracking, isomerization, alkylation, and polymerization. Specifically, it can be used in the isomerization of butene to isobutene. To be used in catalytic processes, the zeolite ferrierite must be heated in an oxidant atmosphere in conditions such that the organic material occluded in the interior is eliminated.

Abstract: The invention relates to a beam former which performs coherent composition of signals originating from a given propagation direction, which are received by an array of <I>N </I> receiving transducers. The inventive methodology and devices are suitable for use in the following fields: radar, sonar, acoustic, seismology, ultrasound imaging (echography and non-destructive testing) and others. According to the invention, the beam former employs arrays having elements which can be distributed randomly. In particular, the invention can be used for dynamic focusing with deflection of the beam in azimuth and elevation, using two-dimensional arrays.

Abstract: A method and apparatus for inline, controlled water separation from a multiphase hydrocarbon production stream. The method includes the steps of directing the multiphase hydrocarbon production stream to a gas/liquid separator in order to separate into a gas stream and a liquid stream. The level of liquid in the gas/liquid separator is monitored and controlled. The liquid stream removed from the gas/liquid separator is directed to an enlarged pipe section in order to separate into an oil portion and a water portion. The level of the oil portion in the enlarged pipe section is monitored and controlled. The water portion from the enlarged pipe section is directed to a liquid-liquid cyclone centrifugal separator in order to separate into a water stream and a hydrocarbon concentrated stream. The water stream from the liquid cyclone centrifugal separator is directed to at least one de-oiling hydrocyclone separator.

Abstract: The invention relates to stone sawing without acute noise. Acute noise, which is produced by the direct friction between the metal bands and the stones, reaches levels greater than 90 db at a distance of 1.5 m between said bands and the measuring apparatus. By increasing the concentration of grit in the sludge and reducing the size of same, the concentration of grit particles can be sufficiently increased such that the bands do not rub against the stone and the annoying noise disappears, enabling an increased feed.

Abstract: An installation for the automatic evaluation of the condition of the rolling band on wheels of moving trains. It comprises a rail beam (1) for each railway line (8), a guard-rail to assure wheel guidance, feelers (P1, P2, P3, P4) intended to come into contact with the wheels passing over them, feeler holders fitted on the rail beam, to ensure wheel-feeler contact, ultrasonics equipment (12) to transmit ultrasonic pulses towards the wheels and to generate the corresponding ultrasonic plots, a local processor (13) to control the ultrasonics equipment and to receive the ultrasonic plot signals generated, a computer (14) connected to the local processor to manage the ultrasonics equipment, and an antenna (15) connected to the computer to identify the compositions of train measurements. The invention is useful to detect cracks in the rolling band of railway vehicle wheels.

Abstract: The sealed closure cap applies specially to containers or bottles which contain carbonated beverages, and has a central neck (6) intented to be introduced into container mouth (2), and an external enveloppe provided with retention means (8, 20) in counterforms of the external surface of the bottle neck, with additional locking means (18, 18′) which ensure the closing position. The cap incorporates an overcap (3, 3′) carrying the seal ring (4, 4′) which surrounds axial fins (7, 8, 20) of the main body of the cap (1, 1′), and can adopt a lower position or nesting position with respect to the cap (1) itself in order to lock the retention means (8, 20) to the external part of the container (2, 22).
