Patent EP-0377571-A1 (EP)
Inventor: DOLFI DANIEL
IPC: G01H9/00
Filed: 1988-07-01
Abstract: Procédé et système d'imagerie par transillumination d'un milieu (H) éclairé par transparence par un faisceau (F1). Un transducteur acoustique (TA1) émet dans le milieu (H) une onde acoustique qui interfère avec le faisceau (F1). La lumière traversant le milieu (H) a alors sa fréquence déplacée de la valeur de la fréquence de l'onde acoustique. Un dispositif de collimation (A), dont le foyer objet est placé à l'intersection de l'onde acoustique et du faisceau lumineux (F1), collecte la lumière diffusée par le milieu (H). Application: imagerie médicale.

Abstract: Le dispositif de congélation décrit est conçu sous la forme d'un récipient essentiellement fermé. Le côté supérieur du récipient comporte une ouverture d'alimentation (16) et une ouverture de décharge. Ces ouvertures sont situées au-dessus du niveau maximum d'un milieu réfrigérant qui est placé dans le récipient et qui à l'état gazeux est plus lourd que l'air. Un premier tube s'étend à travers une ouverture supplémentaire ménagée dans le côté supérieur du récipient et forme un déversoir de trop-plein. Grâce à ce dispositif, le niveau du milieu réfrigérant est maintenu constant dans le récipient et tout excédant du milieu réfrigérant est refoulé par un second tube (32) et par un tuyau (36) relié au tube.

Abstract: Le dispositif électrique décrit permet la conversion de molécules de faible poids moléculaire, telles que du méthane, en molécules de poids moléculaire plus élevé, tel que l'hepthane et l'octane. La chambre de réaction contient un réseau de tubes diélectriques parallèles (32) avec une couche semiconductrice sous leurs surfaces internes (34), cette couche servant à la circulation du courant. Pendant le fonctionnement, des électrons frappent la surface interne (34) des tubes (32), ionisant ainsi des molécules absorbées sur les surfaces, ces molécules étant ensuite accélérées par le champ électrique et transportées vers un nouvel endroit en surface où elles se combinent avec des molécules absorbées à cet endroit pour former une variété de nouvelles molécules plus grandes. L'hydrogène en excès dans un état ionisé est éliminé, en étant accéléré par le champ électrique vers les extrémités opposées des tubes. Dans certaines conditions de fonctionnement, de grandes molécules peuvent être segmentées en molécules plus petites. L'ionisation par impact d'électrons commandée dans le dispositif peut également produire des réactions parmi plusieurs espèces moléculaires qui seraient improbables ou impossibles dans des conditions normales d'équilibre chimique, ou avec des catalyseurs normaux.

Patent EP-0329173-A1 (EP)
Inventor: BROWN DOUGLAS B
IPC: B30B9/28
Filed: 1989-02-17
Abstract: Apparatus for compacting and advancing a mass of particulate or fibrous material to a discharge end of a conduit combines an auger (13) with a reciprocating annular piston (23). The improvement of the invention is in driving the piston by way of a flywheel (55) equipped crankshaft (54) which also drives a dynamically counter balancing member (65) to reduce vibrations transmitted to the frame of the apparatus. Special hydrostatic guide sleeves (26) are used to guide the reciprocating piston (23) at a high speed. Further improvements include gas and liquid vents (68) and a cooling jacket (72), both associated with the conduit (C) to increase efficiency of the compacting. A density sensor (79) controlled conical choke member (87) at the discharge end (78) assists in maintaining uniform density of the highly compacted plug of the material. Also, it breaks up the exiting plug to improve subsequent processing of the material. The uniformity of the compacting is assisted by a modified shape of the leading face of the piston which is flat at the outer periphery and frusto conical near the minor diameter of the piston (23). The conduit (C) preferably tapers at about 7′ to 21′ toward its discharge end (78).

Abstract: The hydrogen content of polysilicon can be reduced by heat treatment. The process is preferably conducted on polysilicon particles in bead-like form produced by chemi­cal vapor deposition in a fluidized bed. The heat treat­ment is preferably conducted at a temperature of 1000-­1200°C. for a time sufficient to reduce the hydrogen content, and insufficient to cause agglomeration of the particles being treated. In order to reduce the tendency of particles to agglomerate at the process temperature employed, the particle bed is preferably maintained in motion during the dehydrogenation. The products produced by the process can have a hydrogen content of 30 ppma or less. These improved products can be used to produce monocrystalline silicon for the production of semicon­ductor devices.

Abstract: The technical field of the present invention is that of sealing devices between a piston rod and a cylinder of an artillery recoil brake. The piston divides the chamber into a high-pressure chamber and a low-pressure chamber. The volumes of the chambers vary according to the position of the piston relative to the cylinder. The sealing device according to the invention includes a "medium-pressure" chamber through which the piston rod passes, and which communicates with the high pressure chamber by means of a roughly annular channel surrounding the piston rod. The medium-pressure chamber is connected to the low pressure chamber by a pipe having a cross sectional area greater than that of the annular channel. The device is intended for applications to artillery material.
