Abstract: Enhanced recovery of oil from subterranean sedimentary formations by an in-situ combustion method employing a pattern of an injection well and several production wells, spaced-apart by a treatment zone. Combustion is controlled by placing at least one fluid conduit in a treatment zone and introducing a control fluid through it to modify the flame front. Oxygen may be introduced to take over from combustion air initially introduced through the injection well, to sustain combustion and advance the flame front. Water may be injected through the injection well, alternating with the oxygen through the control conduit to continue a wet combustion method started with air. The strategic placing of control conduits and the introduction of appropriate fluids may be employed to improve the sweep geometry by advancing the flame front or retarding it, or invading areas behind it. Safety means is provided for introducing the oxygen at a velocity greater than the maximum flame velocity encountered in the flame front.

Abstract: Process for the manufacture, by a sol-gel route and compression with heating, of a composite material consisting of a fibrous reinforcement and of a vitro-ceramic or ceramic matrix based on silica. 
<??>The process of the invention is characterised in that the premature crystallisation of the matrix originating from the sol is delayed by the addition of a crystallisation-retarding agent to the sol. 
<??>This process makes it possible to obtain well-densified composite materials which have a residual porosity of less than 10%, this being done without adding new nucleating agents.

Filed: 1984-09-11
Abstract: The invention relates to a method for purifying aqueous solutions containing at least one impurity element from the group consisting of arsenic, phosphorus, mercury and other heavy metals and solid matter by precipitation in at least two stages with the aid of precipitation reagents possessing ions capable of forming not-readily dissolved hydroxide precipitate. In accordance with the invention the main part of the precipitation reagent is introduced to the stage or stages following the first stage. The impurity element-containing precipitate formed in the aqueous solution subsequent to adding the reagent is separated therefrom substantially completely, and is returned so as to be present in the first precipitation stage, while that part of the solution which has been freed from precipitate in a later stage is withdrawn from the system. Substantially all the impurity element amount present in the ingoing aqueous solution are separated therefrom in the form of a sludge prior to the second precipitation stage.The amount of reagent introduced to the precipitation stages is suitably adapted so that the ratio of equivalence Me to mole of impurity elements, expressed as X is at least 2, preferably 10-15, in the last stage, and at least 0.8, preferably 1-3, in the first stage.

Title: Method of producing flat yarn
Inventor: DAMHORST HUBERT
IPC: D01F6/62
Filed: 1985-09-27
Abstract: A method of producing a flat polymeric yarn is disclosed which includes the steps of melt spinning a polymer to form a plurality of running filaments, combining the filaments to form a running bundle of filaments, and then guiding the running bundle into contact with a ribbon of fluid so as to apply a controlled quantity of the fluid to the bundle. The fluid coated bundle is guided over a plurality of serially arranged curved braking surfaces, and it is then withdrawn by means of a draw roll so as to draw the running bundle to an extent which exceeds its plastic limit. The application of the fluid to the bundle in accordance with the present invention results in a hydrodynamic friction, rather than a sliding contact friction, between the bundle and braking surfaces, and produces yarn of very uniform quality while also avoiding wear of the braking surfaces.

Removal of the flash material intermediate consecutive weld upsets is effected in alternate directions. The anvil edges may be staggered, angled or of helical form to enhance the shearing effect to clear the flash material from the upset weld zone.

Title: High surface area ceria
Inventor: RIECK JEFFERY SCOTT
IPC: B01J37/03
Filed: 1990-11-16
Abstract: A thermally stable, high surface area ceria composition is obtained by intimately adding a ceria stabilizer of one or more of La, Nd or Y to the ceria in an amount of from about 5 to 25 mole % of the ceria. One way to make the product is to mix the stabilizer with a ceria precursor such as cerium nitrate, evaporate the mixture and then calcine the salts to form the stabilized ceria. Another way to make the product is to form an aqueous solution of precursor salts which are precipitated with a base to form hydrous cerous and stabilizer hydroxides or their carbonates. This mixture can be washed and then calcined to form the stabilized ceria. After heating in air for 4 hours at 900 DEG C the stabilized ceria retains a surface area of greater than 20 m<2> /g.
