Inventor: O'BRIEN ROBERT N
IPC: C01B17/775
Filed: 1997-09-26
Abstract: A process for producing in liquid phase, concentrated sulfuric acid in the liquid phase from a source of sulfur dioxide, is described. The process comprises converting the source of sulfur dioxide to sulfuric acid. The liquid phase comprises: a) nitric acid at a sufficient concentration to commence conversion in the presence of oxygen, of sulfur dioxide into sulfuric acid in the initial absence of sulfuric acid, b) nitric acid at a sufficient concentration to maintain conversion of sulfur dioxide in the presence of sulfuric acid either generated by said conversion or present at commencement of said conversion, and c) combined concentration of nitric acid and sulfuric acid ranging from 5M to 16M where the concentration of nitric acid is at least 5M in the initial absence of sulfuric acid, and a source of oxygen is introduced to the aqueous phase at a concentration sufficient to provide for such catalytic conversion of SO2 to H2SO4.

Title: Real-time tracking and mitigating of bending fatigue in coiled tubing
Inventor: ALAN CHARLES JOHN TURNER
IPC: E21B47/00
Filed: 2016-01-12
Abstract: A coiled tubing deployment system includes an offshore rig having a reel positioned thereon and coiled tubing wound on the reel. A guide arch receives the coiled tubing from the reel and a monitoring support guide fixed to the offshore rig receives and directs the coiled tubing into water. The monitoring support guide has a frame and at least two hydraulic rams. A depth counter measures the coiled tubing deployed from the reel and generates length measurement signals, and sensors coupled to the at least two hydraulic rams measure real-time lateral movement of the coiled tubing with respect to the monitoring support guide as the coiled tubing is deployed into the water and thereby generate sensor signals. A data acquisition system receives and processes the length measurement and sensor signals to provide an output signal indicative of real-time bending fatigue of the coiled tubing at select locations along the coiled tubing.

Patent NL-267606-A (NL)
IPC: B01D47/02
Abstract: 941,054. Washing air. ALFRED BULLOWS & SONS Ltd. June 2, 1961 [July 30, 1960], No. 26620/60. Heading B1R. A method of removing water-insoluble materials, e.g. paint, from air comprises passing the air over a cleansing liquid 11 which includes an emulsion of oil and alkaline water e.g. water containing sodium triphosphate or sodium metasilicate, so as to entrain droplets of the liquid in the air. The oil, which may be waste lubricating oil, is preferably present to excess to form a film on the liquid. A fan, not shown, draws the air over the liquid 11 in a tank 10 and under the serrated edge 15 of a plate 14 where it is directed by a plate 16 into a duct 12 containing baffles 13. A film of oil and emulsion is formed on the paint particles which are thus prevented from coagulating, thus allowing the alkaline substances to saponify resins in the paint. The liquid droplets and paint particles fall down the duct 12 and one or more channels 17 which communicate with one or more inverted troughs 18 in the tank 10. A weir 19, having a notched upper edge, forms a trap for paint particles in each trough 18.

Title: Annealing of high tension welding steel
IPC: C21D1/19
Filed: 1969-06-17
Abstract: Steel is annealed under cooling conditions virtually equal to those of a thermal cycle occurring with welding. Allowance is made for the effect of the thermal cycle on the steel surface exposed to the welding heat. The annealing is carried out so that after the steel is heated to a transformation point A3 it is cooled in 5-50 seconds to 500 degrees C and subsequently, in 20-4300 seconds, slowly and continuously from 500 to 200 degrees C, at a speed corresponding with the thermal cycle in welding, so that a transformation of the steel from the austenite structure is brought about.

Abstract: 1441067 Seaming non-metallic sheet material IMPERIAL CHEMICAL INDUSTRIES Ltd 21 March 1975 [16 April 1974] 16446/74 Heading B5K Two thermoplastic polymeric sheets are seamed together by causing the sheets to converge and directing towards the line of convergence at least one focused beam of energy from a laser. The sheets may be films or knitted woven or non-woven fabrics containing thermoplastic continuous filaments or staple fibres, e.g. crimped polyester fibres. During seaming, the sheets may be held stationary relative to each other and to the laser beam or there may be a stepwise or continuous relative movement between the laser beam and the sheets. If the laser beam is movable, its position relative to the sheets may be controlled by a programmer e.g. a punched tape or a magnetic tape. The sheets may be brought together by passing them bwtween two plates, around two bars or between two moving belts. The laser beam, which is preferably pulsed or chopped, may be oscillated over a narrow width to produce a seam comprising two or more rows of weld points. After seaming, the fabric may pass into a laser cutting device controlled by the same programmer which controls the seaming laser. As shown, apparatus for seaming together two fabrics to produce garments comprises fabric supply rolls 1, 2 and driven nip rolls 3, 4 to bring the fabrics together. Two pulsed laser beams 5, 6 are traversed along the nip 7 be tween the rolls 3, 4, the speed of the rolls 3, 4 and the positions of the beams 5, 7 being controlled by a computer. The seams form shoulder seams 10 and side seams 9 of a dress which is subsequently cut-out.

Title: Flotation settler with flexible overflow weir - which moves below the liquid surface as a scraper passes
IPC: B01D21/24
Filed: 1976-02-13
Abstract: A settler has a surface scraper to collect floated material and direct it to the side of the vessel. A trough collects the material. The trough has a wall which can be moved up and down. It is at an angle to a line at right angles to the direction of movement of the scraper. As the scraper passes the top of the wall at that point is lowered below the liq. surface. The moving wall prevents an excessive build up of light material and allows it to be removed without too much water.

Patent NL-7904782-A (NL)
IPC: C11C3/12
Filed: 1979-06-19
Abstract: Unsaturated fatty acid derivatives which, besides fatty acids with two double bonds, contain fatty acids with more than two double bonds, are hydrogenated in the presence of a palladium, platinum or rhodium catalyst which has been treated with ethylenediamine or a homologue and/or a derivative thereof and at a temperature of -20 DEG to 100 DEG  C. The hydrogenation progresses very selectively while very little isomerization to trans-fatty acids occurs. For example, in the hydrogenation of soya bean oil to a linolenic acid content of 2%, the linoleic acid content only decreases to 45-52%. Under identical conditions an untreated catalyst leads to a linoleic acid content of about 35%.
