Abstract: L'invention concerne un procédé de valorisation de l'uranium et des terres rares contenus dans le tétrafluorure d'uranium impur provenant de la récupération de l'uranium de l'acide phosphorique,consistant à le dissoudre à chaud dans un milieu nitrique en présence d'un composé d'aluminium, à traiter la solution obtenue par un solvant d'extraction du nitrate d'uranyle contenant un ester phosphorique et à séparer de la phase aqueuse désuraniée le solvant chargé de nitrate d'uranyle à valoriser. Ce procédé est caractérisé en ce que, dans le but d'obtenir une séparation aisée de la phase aqueuse désuraniée du solvant d'extraction du nitrate d'uranyle: a) on effectue la dissolution de l'UF4 en deux étapes à une température appropriée, la première étape consistant à introduire des quantités insuffisantes d'acide nitrique et du composé d'aluminium pour dissoudre complètement le tétrafluorure d'uranium impur et à maintenir sous agitation la suspension obtenue pendant un temps d'au moins 0,5 heure, la deuxième étape consistant à introduire les quantités d'acide nitrique et du composé d'aluminium au moins suffisante pour mettre en solution l'uranium non dissous dans la première étape et en maintenant sous agitation la suspension; et b) on extrait le nitrate d'uranyle en mettant en contact le milieu aqueux provenant de la dissolution de UF4 et le solvant d'extraction du nitrate d'uranyle contenant l'ester phosphorique.

Abstract: ABSTRACT OF DISCLOSURE    A method for producing a weld-bonded nickel-base alloy coating on a cast iron part with minimum porosity at the weld interface is provided using a plasma transferred arc process in which the cast iron part is electrically coupled to the plasma-forming circuit, the flow of powder being directed into the plasma arc to the surface of the cast iron part.  The method further resides in controlling the deposit of the nickel-base alloy during spraying to maintain a puddle of the alloy between the transfer arc plasma and the cast iron part substrate to protect it from overheating and burning from the transfer arc while promoting a welding reaction between the puddle and the cast iron substrate.  The plasma spraying is continued progressively along the cast iron substrate to be coated while maintaining the alloy puddle between the plasma arc and the cast iron until completion of the coating thereof.  The invention also relates to a composite article of manufacture.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a process for reacting a compound containing silicon-bonded hydrogen with a compound containing aliphatic unsaturation in the presence of actinic radiation and to compositions that contain an actinic radiation-sensitive catalyst that are used in the process.  Although many platinum complexes are useful as catalysts in processes for accelerating the thermally-activated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for accelerating the ultraviolet radiation activated addition reaction between these compounds, using a platinum complex as a catalyst, are not known.  The ultraviolet radiation activated addition radiation can be conducted in the presence of a platinum complex having an ultraviolet displaceable group, e.g. a ( -diolefin)( -aryl) platinum complex.  This process is useful for the in situ curing of a polymeric silicone composition to a solid surface, particularly one which is heat-sensitive.

Abstract: ABSTRACT    METHODS AND APPARATUS FOR FORMING TUBULAR CLOSED-ENDED          ARTICLES OF THERMOFORMABLE POLYMER MATERIAL   A tubular article with a closed end is formed from a thermoformable polymer material, e.g. a high molecular weight saturated linear polyester such as polyethylene terephthalate, by forcing a punch (21) through the plane of a pre-heated and clamped sheet (13) of the polymer, centrally within an annular die (10), so as to draw the sheet into tubular form without exerting compressive stresses on the sheet between the punch and die, the punch being maintained at a temperature below the glass transition temperature of the polymer, e.g. by passing cooling fluid through internal passages (16), and being moved at a speed of at least 1/2 metre per second to effect the drawing.  The punch head (21) may be convex or concave to produce a shaped closed end on the article, e.g.  for making a pressure-resistant container, and the punch may co-operate with a shaped movable anvil (201) at the end or at an intermediate point in its stroke.          Replaceable annular spacers (24) can be used to adjust the point in the punch stroke at which it co-operates with the anvil.

IPC: F02M25/00
Filed: 1985-01-30
Granted: 1987-11-24
Abstract: ABSTRACT   A control system for a dual fuel engine using primary diesel fuel and supplemental gas fuel such as propane or natural gas includes a control valve that controls supplemental fuel mixing with intake air by using an air deflectable member that controls the position of a valve controlling the admission of supplemental gas to the engine intake airstream. A damper is provided on the air flow responsive member to improve valve operation and a lost motion connection is provided between the air flow responsive member and the control valve element to permit independent movement of the elements. Normal flow of supplemental fuel to the control valve is further modulated in response to certain engine operating conditions using an engine condition comparator that generates a control signal used by the supplemental fuel pressure regulator to further modulate the supply of supplemental fuel to the intake airstream. The system includes a supplemental fuel shut-off system that restores full primary diesel fuel flow to the engine when the supply of supplemental fuel approaches depletion.

Abstract: ABSTRACT OF THE DISCLOSURE         A novel method for the diagnosis of Acquired Immune Deficiency Syndrome (A.I.D.S.) is disclosed, involving the use of immunocytoadherence (rosette inhi-bition) techniques. The method is based on the discov-ery that the lymphocytes of A.I.D.S. patients are unus-ually resistant to antithymocyte serum, and that the plasma of A.I.D.S. patients is capable of conferring this resisitance to normal lymphocytes.  Accordingly, the diagnostic method involves performing rosette inhi-bition tests on the patient's lymphocytes or on lympho-cytes from a healthy donor after treatment with the patient's plasma.  Any observable lessening of inhibi-tion in comparison with a control is related to the presence of A.I.D.S.

Abstract: ABSTRACT (Figure 4) A remote sensor for detecting gas, vapour or aerosol comprises means to measure the change in temporal coherence of light of a selected narrow waveband when it interacts with the gas etc.  The light can be provided by a laser source or spectrally filtered sun light etc. Received radiation is split in to two beams by a Fresnel biprism and then detected by a detector sensitised by a modulating reticle to interference fringes.  A glass delay plate of suitable thickness is placed in the path of one of the beams such that only received radiation having a temporal coherence greater than a minimum determined by the plate thickness produces an output signal from detector.  The minimum temporal coherence is set higher than the temporal coherence of the illuminating radiation.  In alternative arrangements a band-pass temporal coherence filter may be used and the sensor can be made to spectrally scan the field of view by using a tunable laser or a variable centre frequency band-pass optical filter.

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for winding field coils on internal poles of stator bodies, particularly for electric motors, have a magnet wire feeding needle or needles displaced eccentrically from the central armature axis of the stator body.  The or each such feeding needle is disposed to reciprocate and partially rotate on an eccentric axis located between the central armature axis and the internal pole being wound.  Due to this eccentricity, during the partial rotation of the feeding needle, the end turns of the coil are lifted above the end of the pole and laid more precisely in place.  This enables the conventional winding forms to be eliminated allowing a reduction in the length of the reciprocating stroke of the feeding needle and faster winding with reduction in "snap back" effect.  A further cost saving occurs from a shorter length of the end turns resulting in less wire being used.
