Patent EP-0528894-A1 (EP)
Inventor: BRYCE WILLIAM DEAN SHORTHEATH
IPC: F02K1/38
Filed: 1991-05-13
Abstract: Un moteur à turbine à gaz pour avion supersonique fait appel à une configuration variable pour réduire le bruit du réacteur au décollage sans compromettre son rendement aux vitesses de croisière élevées. En configuration décollage, des prises d'air supplémentaires (21) s'ouvrent pour faire entrer de l'air ambiant dans la conduite de dérivation (20). L'air du conduit de dérivation et l'air ambiant ainsi entraîné se mélangent avec le flux central du moteur à l'extrémité amont de la tuyère (30) pour sortir par une grosse tuyère commune finale (32). L'ouverture et la fermeture des prises (21) s'effectue en actionnant des volets à ouverture variable (17, 22 et 32), l'ouverture des volets (17 et 22) étant réduite quand les prises (21) et la tuyère (32) sont ouvertes. Ce procédé permet d'obtenir un mélange efficace le plus en amont possible, ce qui réduit la vitesse du jet d'échappement et donc le bruit produit par le réacteur. En vol de croisière, le moteur adopte la configuration d'un réacteur classique à faible taux de dilution: les prises (21) sont fermées, les volets (17 et 22) sont ouverts et la section de la tuyère (32) est réduite.

Abstract: La préparation d'un matériau de matrice métallique composite contenant des particules discontinues dans une matrice métallique consiste à former un mélange de l'alliage fondu et des particules dans le réacteur fermé, à enlever l'oxygène de l'intérieur du réacteur, à pressuriser de manière statique l'intérieur du réacteur à l'aide d'un gaz d'azote, à mélanger le mélange d'alliage fondu et de particules en présence du gaz d'azote pour mouiller la matrice fondue des particules, et à vider l'intérieur du réacteur par étapes. Le gaz d'azote aide les particules à mouiller l'alliage métallique en produisant du nitrure d'aluminium au niveau de l'interface entre les particules et la matrice fondue, de sorte qu'un angle de contact inférieur de l'alliage à la particule en résulte. De l'oxygène qui peut être présent dans le réacteur hermétiquement fermé est dégazé par l'aluminium, et l'azote est enlevé par une évacuation par étapes, ce qui diminue l'introduction et la rétention de gaz dans la matière en fusion.

Abstract: A support for circuit boards, with snap mounting on standard cap rails, contains two grooves (16, 17) for the attachment of a circuit board (22), in addition to the grooves (14, 15) which are used for snapping onto the cap rail (1). The grooves (16, 17) are located in expanded attachment elements (8, 9) which are arranged in an elastically bending manner on the ends of a web (5) whose end regions are constructed in the shape of thin boards (6, 7). All the grooves (14-17) are directly adjacent to the thin boards (6, 7) on both sides so that, in the assembled state, the mutually aligned flat edge strips (3) of the cap rail (1) and the circuit board (22) rest tightly against the thin boards (7). This results in a small installed height as well as locking as a result of the counteraction of the spring effect of the boards (6, 7). An attachment element (8) according to the invention ensures a large spring length for its part (10) which is also used for detaching the effective connection to the cap rail (1). <IMAGE>

Abstract: A drop-on-demand ink-jet printing head provided with an array of a plurality of piezoelectric elements (12,12') arranged at regular intervals and fixed at their one ends to a base (2), the other ends of the respective piezoelectric elements being free ends which are disposed in opposition to nozzle respective apertures (10,10'), the piezoelectric elements being formed by cutting, at predetermined width, a piezoelectric plate obtained by firing a lamination of paste-like piezoelectric material and conductive material stacked alternately in layers. Since each piezoelectric element is composed of a thin piezoelectric plate interposed between electrodes, if a voltage of only about 30V, which is sufficient to drive the thin piezoelectric plate, is applied across the electrodes, it is possible to largely flex the whole of the piezoelectric element. By this transformation, ink between the top end of the piezoelectric element (12,12') and the nozzle aperture (10,10') is discharged to the outside as an ink drop. Because the driving voltage required for forming an ink drop is as low, it is possible to simplify a driving circuit, and because of cutting a piezoelectric plate, it is possible to form small-sized piezoelectric elements with the same accuracy as in a process of producing a semiconductor.

Abstract: Catalyst for chemical and petrochemical reactions and process for its manufacture. The catalyst comprises an oxide of one of the transition metals, of the rare earths or of an actinide, for example of molybdenum, comprising carbides and oxycarbides at the surface, it being possible for the core to be the metal or the oxide. The process of manufacture consists in passing over the oxide the reaction gas mixture containing carbonaceous products whose catalytic chemical conversion it is intended to carry out at the temperature of this reaction. The carbonaceous products present in the mixture cause a progressive carbiding of the surface of the oxide and an equally progressive increase in the efficiency of the catalyst. The process applies in particular to the reforming of hydrocarbons, for which molybdenum oxide MoO3 constitutes a preferred catalyst.
