Abstract: In a vortex-shedding flowmeter the fluid is conducted through a pipe having a shedder (11) fixedly mounted therein. A sensor (12) is torsionally supported downstream behind the shedder (11) on a pivot axis (Y') normal to the flow axis. The torsional support includes a torque tube (14) whose base (14A) is received within a bore in the pipe and is welded thereto and whose tip (14B) is welded to one end of the sensor. As the incoming fluid stream flows past the shedder (11), vortices are successively detached therefrom and appear alternately on either side of the sensor (12) to develop alternating torques about pivot axis (Y'), causing the sensor (12) to oscillate at a rate proportional to the fluid flow rate. These oscillations are converted into corresponding electrical signals by an external torque transducer (15) operatively coupled to the sensor by a sensor link assembly including a rod (18) which extends coaxially into torque tube (14) and is welded to the tip (14B) thereof.

Abstract: Pour former des materiaux cellulaires synthetiques, on produit du gaz par la reaction d'un isocyanate et d'un hydroperoxyde. Les produits de reaction donnent une nouvelle mousse d'oxyde d'amine polymere. Lorsque les produits de reaction sont introduits sur une resine de base, des produits dits de mousse cellulaire (densites sur toute la plage comprise entre 50 et 2 lbs/ft3), on peut obtenir des produits de resine expansee de densite encore superieure, et des solides resineux exempts de retrait (avec une distribution microcellulaire de gaz). Lorsqu'ils sont utilises dans des resines polymerisables avec de l'hydroperoxyde, une petite fraction de l'hydroperoxyde agit avec un activateur et sert a polymeriser la resine tandis que la fraction la plus importante reagit plutot avec l'isocyanate pour degager du gaz avant d'atteindre l'etat de gelification de la resine de base. L'agent de moussage peut etre rendu disponible dans le commerce comme un pre-melange d'isocyanate et d'un agent tensio-actif approprie pour la reaction de l'hydroperoxyde. Par melange avec une resine de base a carboxyle et hydroxyle faible, on peut obtenir une longue vie de conservation. L'hydroperoxyde est maintenu separe jusqu'a ce que l'on desire effectuer la production de cellules ou moussage dans la resine de base.

Abstract: Un systeme de reproduction haute fidelite utilisant au moins un (pour le mono) ou une pluralite de haut-parleurs conjointement avec, par exemple, un systeme de production de sons conventionnel (tels que stereo, casque d'ecoute, aides auditives, et trois schemas de haut-parleurs) et un circuit de correction d'images qui assure une meilleure reproduction en corrigeant la position angulaire des images. Le systeme comprend par exemple un, deux ou trois transducteurs dans des positions geometriques diverses telles que deux haut-parleurs disposes devant la personne qui ecoute (p.ex. a des angles de 45 a partir d'une ligne de vue - Fig. 3, 4) ou derriere la personne qui ecoute (comme dans la Fig. 16). Trois dispositions geometriques de haut-parleurs peuvent egalement etre utilisees (Fig. 18 et 24). Le mode preferentiel de realisation prevoit egalement que le circuit puisse etre utilise avec par exemple un amplificateur stereo (Fig. 1 et 14) lorsqu'il est utilise avec des haut-parleurs/casques d'ecoute stereo conventionnels ou qu'il puisse etre utilise comme un appareil d'aide auditive. Le circuit ameliore la separation des composants individuels de production de sons (tels que des tambours, un chanteur, une trompette, un violon et autres) tout en tenant compte de l'effet "d'ombre de tete".

Abstract: @ In a coal gasification operation (32) or similar conversion process carried out in the presence of an alkali metal-containing catalyst wherein particles containing alkali metal residues are produced, alkali metal constituents are recovered from the particles by contacting them (46, 53, 61, 69) with water or an aqueous solution to remove water-soluble alkali metal constituents and produce an aqueous solution enriched in said constituents. The aqueous solution thus produced is then contacted with carbon dioxide (63) to precipitate silicon constituents, the pH of the resultant solution is increased (81), preferably to a value in the range between about 12.5 and about 15.0, and the solution of increased pH is evaporated (84) to increase the alkali metal concentration. The concentrated aqueous solution is then recycled to the conversion process (86, 18, 17) where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal containing catalyst.

Title: A method in the manufacture of sulphuric acid from gases generated in discontinuous processes.
Inventor: PETERSSON STIG ARVID
IPC: C01B17/76
Filed: 1982-10-22
Abstract: Method of utilizing process gas containing sulphur dioxide obtained from discontinuous processes, in the manufacture of sulphuric acid in a contact plant. When practicing the method according to the invention, all of the process gas, or a predetermined amount thereof, is withdrawn from the process during process operational periods, in which gas containing sulphur dioxide is generated, and the sulphur dioxide contained by the withdrawn gas is at least partially separated therefrom to form a liquid phase containing the amount of sulphur dioxide separated. The gas partially freed from sulphur dioxide, together with any non-withdrawn process gas, is passed to the contact plant for manufacturing sulphuric acid. Stored absorption liquid is utilized during those periods in which no process gases are produced or passed to the contact plant or in which the process gases contain insufficient sulphur dioxide. Sulphur dioxide is stripped from the liquid phase with the aid of a carrier gas, and the carrier gas, together with the stripped sulphur dioxide, is passed to the contact plant. This enables a required amount of gas and sulphur dioxide to be constantly supplied to the contact plant, even during those periods when the discontinuous process does not produce a sulphur-dioxide-containing gas or produce a gas having an insufficiently high sulphur-dioxide amount.

Abstract: The device has an annular frame (1, 2, 3) formed from a cylindrical bearing surface (1) and limbs (2, 3). Arranged on the inside of the frame (1, 2, 3) is a flexible tubular conduit (9) whose inner conduit wall (21) forms a running surface for pressure rolls (12), which effect the conveyance of the conveying means through the rotation along the conduit (9). Provided on the outer conduit wall (20) are bolts (14) which are arranged spaced apart and rigidly connect the outer conduit wall (20) in the region of its apex to the bearing surface (1). Due to the fact that the conduit (9) is held on the bearing surface (1), the conduit (9) is pressed together uniformly by the rolls (12), as a result of which a substantially smaller power input is required than with known designs. It is therefore possible to build conveyors of large conveying capacity. <IMAGE>

Abstract: The invention relates to a process for the production of patterned lustre coatings on surfaces of bodies of glazed ceramic, in particular, tiles, glass or enamel using a cover corresponding to the pattern to be produced. On the surface of the body acting as substrate, a negative of the pattern is produced by a paste applied by screen printing, the body provided with the pattern negative is heated in a furnace to a temperature above approximately 400 DEG  C., the body is subsequently dipped into the solution of a metallic compound which reacts with the surface of the body not covered by screen printing to form a thin layer of the metal and oxides of the metal. In the metal/metal oxide layer of the body whose surface is cooled down by dipping, lustre colors are produced by heat input. Finally, after formation of the lustre colors, the screen printing paste constituting the pattern negative is removed from the body.
