Abstract: Appareil destiné à améliorer les propriétés d'une matière solide en appliquant à cette matière des ondes de choc. Un oscillateur laser (10a) produit un certain nombre d'impulsions (112) de rayonnement cohérent. Le bord d'attaque de chaque impulsion est affiné soit par une feuille métallique (18) soit par un dispositif de réflexion-conjugaison de phase (18a, 18e) comportant une cellule de diffusion stimulée Brillouin (18d, 18e) et, facultativement, un isolateur de Faraday (18b). Chaque impulsion est dirigée vers un amplificateur (123) comprenant une première et une seconde barres amplificatrices laser (23a, 23b) en série. Au moins un secteur principal de rayonnement (112) amplifié par la première barre d'amplification (23a) est dirigé sur la deuxième barre d'amplification (23b), ou elle est amplifiée puis dirigée sur la surface de la matière solide. On obtient une amplitude spatiale uniforme du rayonnement (112) selon, au minimum, l'une des procédures suivantes: une paire de lampes à éclat (70, 71) est incluse dans chaque barre d'amplification laser (23a, 23b) pour pomper dans ladite barre; l'axe de chaque lampe à éclat (70, 71) et l'axe de la première barre (23a) sont pratiquement parallèles et se situent pratiquement dans le même premier plan; un (deuxième) plan dans lequel s'inscrit l'axe de la deuxième barre (23b) et les axes parallèles de ces lampes à éclat associées (70, 71) est essentiellement perpendiculaire au premier plan; et/ou l'oscillateur (10c) produit un rayonnement (12T) cohérent non polarisé dont les caractéristiques d'amplitude spatiale de chaque impulsion successive sont essentiellement une image fidèle des caractéristiques de l'impulsion l'ayant précédée, ou bien cet élément pivote autour de son axe en décrivant un angle prédéterminé plus petit que celui des caractéristiques de l'impulsion précédente.

Abstract: An agent for the desulphurization, dephosphorization, desilicization and denitrification of molten iron, ferrochrome and ferromanganese consists of at least one of the following mineral raw materials: alkali-containing plagioclases, alkali-containing orthoclases, montmorillonites (perlite), bentonite, vermiculite, muscovite or zeolite as well as calcium carbide and/or calcium oxide. In combination with calcium carbide, lime, iron ore or scale, mineral constituents lead at the treatment temperatures to effective reduction in undesired accompanying elements such as sulphur, phosphorus, silicon and nitrogen in the molten metals. The resulting slags can very readily be tapped and contain less iron granules than in the case of a treatment with conventional agents. If appropriate, suitable minerals can be concentrated by sintering or in the molten state with alkali metal oxides. The process for treating molten iron, ferrochrome and ferromanganese is characterized by the introduction of the agent by blowing in, stirring in, mixing by shaking of the melt, in a premixed form or by separate addition of the individual components.

Abstract: We describe encoding and decoding of digital data with different degrees of error protection. The uniform-sized user elements of data are distributed over an array, encoded according to a first dimension by adding first redundant elements of said uniform size corresponding to a first linear code, and encoded according to a second dimension by adding second redundant elements of said uniform size corresponding to a second linear code. In particular, the first linear coding for at least one first line of user elements realizes a higher degree of error protection than for at least one second line of user elements and the former is realized as a first code that has more of said first redundant elements than the latter that is realized as a second code.

Abstract: The leading edge (22) of a nacelle (20) for an aero-engine (10) is porous. The porous leading edge (22) has laminar flow control and contamination protection. 
     At take off and landing a liquid is selectively distributed through channels (30) to regions D and F of a layer of porous material (24). The liquid permeates slowly through the pipes (32) located in the channels (30). The pipes (32) resistance to the flow of liquid therethrough causes a pressure to develop which is sufficient to dispense the liquid through the layer of porous material (24). The exuded liquid provides contamination protection at the leading edge (22) of the nacelle (20). 
     At cruise a chamber (36) adjacent inner surface (26) of the porous layer (24) is evacuated to selectively suck air through the porous layer (24). The suction provides laminar flow control by preventing the onset of turbulence in the boundary layer air flow passing over the nacelle (20).

Abstract: A non-refill valve (1) for a non-refillable container, comprising a valve body (7) having an inlet (9) and an outlet (11) and a passage through the valve body (7) interconnecting the inlet (9) and the outlet (11). A valve stem (13) slides in the passage (15) and has an axial passageway (15) that extends partway therethrough and that terminates laterally in a passageway (17) that extends through a side wall of the stem (13) intermediate the ends of the stem. A ball (21) in the stem (13) rests on a seat (23) on the stem (13) and closes the valve stem passageway (15) against the flow of gas from the outlet (11) towards the inlet (9). A first spring (25) urges the ball (21) against the seat (23) to permit flow of gas only in a direction from the inlet (9) to the outlet (11) by displacing the ball (21) from the seat (23) against the action of the first spring (25) in an open position of the valve (1). A second spring (45) urges the stem (13) in the direction of the flow of gas from the inlet (9) to the outlet (11), and a seal (49) acts between the stem (13) and the valve body (7). The second spring (45) urges the seal (49) into sealing relation with the valve body (7) in a closed position of the valve (1), whereby when a coupling (5) is attached to the valve body (7), the coupling (5) urges the stem (13) in a direction opposite the first-mentioned direction and against the action of the second spring (45) to move the seal (49) out of sealing relation with the valve body (7), thereby to establish communication between the inlet (9) and the outlet (11) when the pressure of a gas in the inlet (9) is sufficient to move the ball (21) off the seat (23) against the action of the first spring (25).
