Abstract: SOLID CARBONACEOUS FUEL FEED        (D#74,323-F) ABSTRACT OF THE DISCLOSURE          This is an improved continuous partial oxidation process for producing synthesis gas or fuel gas from gaseous CO2-solid carbonaceous fuel feeds.  A solid carbonaceous fuel such as finely ground coal from a pressurized lock hopper is passed directly into a high pressure high velocity CO2-rich gas stream which carries the particles of coal into a free-flow noncatalytic gas generator where by the partial oxidation reaction with a free-oxygen containing gas, preferably in the absence of supplemental H2O other than that normally present in the reactants, gaseous mixtures principally comprising H2, CO, CO2, and H2O are produced.  A CO2-rich gas stream is recovered downstream in the process and recycled to the pressurized feed system. The CO2-rich stream serves as a carrier for the carbonaceous fuel and as a reactant in the reaction zone.                             -I-

Abstract: PRECIS DE LA DIVULGATION:           L'invention concerne un procédé d'assemblage d'élé-ments métalliques ou non par fusion d'un métal ou alliage d'ap-port.  Ce procédé consiste  à  chauffer les éléments  à  assembler sur lesquels le métal ou alliage d'apport a été mis en place à proximité des points où les liaisons doivent être réalisées, dans une enceinte vidée d'air dans laquelle on place en une pe-tite quantité d'un composé halogéné qui s'évapore au moins en partie pendant le chauffage.  On constate que les vapeurs ha-logé?ées produites décapent les pièces à assembler et favorisent leur mouillage par le métal ou alliage d'apport.  Ce procédé convient pour tous types de brasage et plus particulièrement lorsqu'on exige à la fois un pénétration parfaite des joints et l'absence de toute trace de flux.  C'est le cas en particulier d'assemblages utilisés dans les réacteurs nucléaires; c'est le cas également de toutes sortes d'assemblages utilisés dans le domaine aérospatial.

Abstract: SELF-MODULATED CLUTCH WITH DRAG-REDUCTION VALVE     A B S T R A C T     A clutch for coupling an engine to a transmission gearbox engages and disengages automatically in response to engine speed variation.  Springs hold the clutch pressure plate retracted from the clutch discs at idling speeds.  As engine speed increases, centrifugally generated fluid pressure in the clutch lubricant overcomes the spring force and applies a modulated engagement pressure to the discs.  An internal valve continuously supplies an oil flow to lubricate and cool the clutch components and to charge the centrifugal pressure-generating means.  Retraction of the pressure plate shifts the valve to reduce the oil flow while the clutch is disengaged.  This reduces viscous drag within the clutch and thereby assures a more controlled disengagement.  Retainer means stores some of the reduced oil flow to assure that ample fluid is avail-able to the centrifugal pressure-generating mechanism when engagement commences.

Abstract: ABSTRACT OF THE DISCLOSURE       A collection system having a vacuum source in flow communication with a closed fluid collection vessel which is in flow communication with an inlet conduit disposed to apply the vacuum to non-gaseous fluids.  The non-gaseous fluids to be collected are ingested through the inlet conduit through an inlet port to the closed collection vessel where they are retained.  The collection vessel is kept at a negative/gauge pressure through an outlet port connecting-the collection vessel to the vacuum source.  A variable restriction means is provided at one point between the outlet port and the vacuum source for reducing the cross-sectional area available for flow.  The restriction means is responsive to the pressure differential across it and thus tends to reduce gas flow through the system in response to increasing differential pressure.

Abstract: A machine for making from a thin strip of filtering material a flat, resilient folded structure having on  each of its two faces a row of parallel folded ribs having zig-zag ridges and corresponding to a row of grooves on the other face, each rib ridge being connected to each zig-zag line at the bottom of the adjacent groove via a folded flank formed by a succession of facets in the form of parallelograms.  The machine has two marking rollers on parallel axes disposed respectively on either side of the path of the strip and driven in synchronism with the object of marking on the two faces of the strip imprints defining the ridges of the ribs and the folds of the folded structure.  Each roller has first and second projecting marking lines, the first of which correspond to the rib ridges or groove bottoms and the second corresponding to the folds of the flanks of such ribs or grooves respectively.  The first marking lines extend over each of the two marking rollers in annular parallel zig-zag lines centred on the axes of such rollers; the second marking lines extend over each of the rollers from the angular points of the zig-zag lines.  A guide passage is bounded laterally by two faces converging downstream and the structure is impelled in the course of folding at constant speed in such passage.  The marking is such that the folded ribs extend lengthwise of the strip and the passage is fixed and bounded vertically by two smooth faces which diverge progressively downstream such that the cross-section of the inlet to the passage is substantial complementary to the flattened rectangular section of the undeformed marked strip. The two divergent faces have smooth longitudinal guide ribs whose heights increase downstream and whose centre lines converge downstream, extending in accordance with the centre lines of the hollows between the folded ribs to be shaped.

Abstract: ABSTRACT      In the continuous casting of metals by means of a water-cooled tubular mold into which the molten metal is fed by means of a refractory pouring nozzle which opens in the molter metal bath below a supernatant protective layer of fusible slag, automatic control of the molten bath level is obtained by forming an image of the upper portion of the mold with the pouring nozzle and the slag layer by means of an optical ins-trument, by disposing a plurality of photo-electric cells on this image along a line substantially coin-cident with the axis of the nozzle on the said image, some of said cells being on the image of said nozzle and others on the image of the slag layer by deter-mining the radiation gradient between the successive cells along said line by taking as the analog of the level of the molten metal bath within the mold the zone of said line where said gradient reverses and by deducing a controlling signal from the position of said zone along said line. The successive cells may be connected two by two to comparators which emit an output in correspondence with the sign of the diffe-rence between the responses of the cells of each pair, these outputs being totalized algebraically to deduce the controlling signal.
