Abstract: Abstract The method and apparatus for forming a directional and controlled suspension spray of a pulverous material and a reaction gas is intended for use in, for example, metallurgical processes and plants. In many metallurgical processes, e.g. in flash smelting, reaction gases are fed into a cylindrical vertical reaction chamber centrally through the top of the reaction chamber. The blasting in is via a specific blast-in member, into which the gases are usually directed horizontally for reasons of space use. This results in that the flow in the reaction chamber is asymmetrical. This disadvantage can be eliminated by means of the method and apparatus according to the present inven-tion. The method according to the invention is characterized in that a pulverous material is directed into the reaction chamber mixed with part of the reaction gas, and the rest of the reaction gas is directed into the reaction chamber in at least three separate, at least partly turbulent sprays symmetrically around the flow of the pulverous material, and the reaction gas sprays are caused in the reaction chamber to discharge into the flow of the pre-dispersed pulverous material in order to produce a turbulent but controlled suspension spray. The apparatus according to the invention is, for its part, characterized in that around the member (3) for feeding a pulverous material there is coaxially situated a reaction gas distribution member (7), from which there depart at least three regulatable reaction gas discharge pipes (8) which are oriented towards the reaction chamber and situated symmetric-ally around the member for feeding the pulverous material.

Abstract: ABSTRACT OF THE DISCLOSURE     A multi-zone  fluidized bed hydrocarbon  conversion pro-cess and apparatus for producing gas and distillable liquid products  from heavy hydrocarbon feedstocks.   The feedstock is introduced into an upper fluidized bed primary cracking zone  maintained  at  temperature  of 850-1400°F  for  cracking reactions therein, and resulting tars and coke are deposited on  and  within  a  particulate  carrier  material  contained therein.   The carrier material containing said tars and coke descends  successively  through  a  stripping  zone  to  remove tars and an interim controlled temperature zone for secon-dary cracking  against an upflowing hot reducing gas,  then descends into a lower fluidized bed gasification zone.   The gasification   zone   is   maintained   at a temperature   of 1600-1900°F  by  oxygen-containing  gas  and  steam  introduced therein to gasify the coke deposits and produce the reducing gas.    The  stripping  zone  contains  a  stationary  packing material  such as  coarse particulate packing which is  sup-ported by a refractory apertured grid, or an ordered array of multiple  structural members.  The  decoked hot particulate carrier material is recirculated upwardly through a transfer conduit to the upper fluidized bed primary cracking zone by a transport gas.    Hydrocarbon liquid and gas products are withdrawn from the upper cracking zone.

Abstract: ABSTRACT           The present invention is an improved method for stabilizing acetal copolymers by hydrolyzing the copolymer product in a low energy reaction process wherein undesirable side products are continuously and efficiently removed by melting and extruding the unhydrolyzed oxy-methylene copolymer into a hydrolysis reaction zone in which the necessary reactants are intimately contacted with the copolymer, preferably by means of flow division and rearrangement mixing technique. Subsequently, the hydrolyzed copolymer product is devolatilized to remove the unwanted side products by passing it through a devola-tilization zone preferably having more than one devolatilization port and a vacuum source from which negative pressure is available for application to the devolatilization ports so that the undesired products may be effectively removed.

Abstract: ABSTRACT.            Surface modified, skinless, hydrophilic, microporous, polyamide membranes with controlled surface properties are prepared by the steps of preparing a casting solution comprised of (A) a casting resin system comprised of (a) an alcohol-insoluble polyamide resin, and (b) a water-soluble membrane surface modifying polymer having function-al polar groups and a molecular weight of 10,000 or greater, and (B) a solvent system in which the casting resin system is soluble; inducing nucleation of the cast-ing solution by controlled addition of a non-solvent for the casting resin system under controlled conditions to obtain a visible precipitate of casting resin system particles, thereby forming a casting composition; spreading the casting composition on a substrate to form a thin film; contacting and diluting the film of the casting composition with a liquid non-solvent system for the casting resin system, thereby precipitating the casting resin system from the casting composition in the form of a thin, skinless, hydrophilic, surface modified, micro-porous, polyamide membrane; and washing and drying the membrane.  The membranes of this invention are character-ized by having fine pore ratings, the surfaces properties thereof being substantially controlled by functional polar groups of a membrane surface modifying polymer and having the capability, through the functional polar groups of the modifying polymer, of reacting or interacting with particulates and/or  nonparticulates in a fluid.  Membranes of this invention are useful in removing metal species from aqueous streams and in immobilizing enzymes.  membranes of this invention also have enhanced filtration efficiency over a broad pH  range with very fine contaminants, particularly very fine positively charged particles , such as asbestos.

Abstract: Procédé de mesure par ultrasons du rapport du volume de gaz présent dans une enceinte contenant un mélange diphasique liquide-gaz au volume de l'enceinte, ou taux de vide. On provoque la propagation d'ondes à des fréquences différentes, à travers le fluide remplissant l'enceinte. On mesure les temps de propagation des ondes et on calcule la différence entre ces temps de propagation. Si les temps de propagation sont identiques, on en déduit que tout le gaz est sous forme d'une couche surmontant le liquide. On détermine le taux de vide à partir des vitesses de propagation des ultrasons dans le gaz et le liquide et du temps de propagation mesuré. Si les temps de propagation sont différents, une partie du gaz est sous forme de bulles dans la vapeur, on détermine séparément le taux de vide dû au gaz surmontant le liquide et le taux de vide dû aux bulles de gaz dans le liquide. On détermine le taux de vide total par addition des deux valeurs obtenues. Le taux de vide dû au gaz surmontant le liquide peut être déterminé grâce aux ondes réfléchies par l'interface gaz-liquide. Le taux de vide dû aux bulles de gaz est déterminé grâce aux relations existant entre la vitesse des ultrasons et la fréquence des ondes, suivant la pression et le taux de vide. L'invention s'applique, en particulier, à la mesure du taux de vide dans une partie du circuit primaire d'un réacteur nucléaire à eau sous pression, après un incident.

Abstract: APPARATUS FOR MEASURING THE REFRACTIVE INDEX OF AN OPTICAL FIBER                             ABSTRACT       The apparatus described basically includes a vessel which has a horizontal transparent window and contains an index liquid.   An optical fiber is mounted in this vessel perpendicular to the window.  Light is launched and focused by a condenser onto fiber.  The light cone of aperture angle due to the guided and leaky modes is eliminated using an annular mirror that reflects the remaining portion of the aperture light cone escaping laterally from the fiber.  This light reflected by the mirror is focused by an annular con-denser and reflected onto a detector by a flat mirror with a hole in the center.  Measuring the amount of light received by the detector allows the refractive index of the fiber to be determined.
