Title: Systeme de vidange pour cuve de stockage
Inventor: WITTER ALDYR
IPC: B01D17/02
Filed: 1997-09-18
Abstract: Cette invention a trait à un système rendant possible l'évacuation de liquides indésirables, en phase aqueuse, d'une manière générale, précipitant au fond de cuves de stockage de produits liquides. Le dispositif de vidange (30) utilisé comporte un corps concave (31), un siège (26) et un flotteur de séparation (8) pourvu d'un partie d'obturation (25). Ce flotteur (8) est conçu pour plonger dans le produit en phase aqueuse et y flotter. Lorsque le niveau de produit en phase aqueuse descend, la partie d'obturation (25) se fixe de manière hermétique sur le siège (26) faisant, de la sorte, cesser le processus de vidange puisque tout le produit en phase aqueuse accumulé a déjà été évacué. Le système de vidange peut être automatique ou manuel. Dans le premier cas il est fait usage d'un capteur (12) destiné à déceler la présence d'un produit en phase aqueuse et à commander la procédure d'ouverture d'une vanne de fermeture (11) et, partant, à permettre la vidange du produit en phase aqueuse accumulé. Dans le cas d'un fonctionnement commandé manuellement, un opérateur inspecte périodiquement, grâce à une ouverture (28), la cuve de stockage (1) afin d'y déceler la présence d'un produit en phase aqueuse. Si celui-ci est en train de s'y accumuler, il ouvre une vanne de fermeture (11) à commande manuelle (29) afin de procéder à son évacuation.

Title: Process for preparing poly(alkylene carbonate) monoahls and polyahls useful as surfactants and novel compositions of matter
Inventor: HARRIS ROBERT F
IPC: C08G64/04
Filed: 1989-11-23
Abstract: ABSTRACT         Poly(alkylene carbonate) monoahls and polyahls having a poly(alkylene carbonate) backbone are prepared by reacting an oligomeric poly(alkylene carbonate) with a compound having mono- or difunctional active hydrogen moieties, such as alcohols, carboxylic acids, mercaptans, amides, primary or secondary amines, or substituted phenols, in the presence of a catalyst under transesterification conditions.  These monoahls and polyahls are useful as mom-ionic surfactants.  The compounds having active hydrogen moieties become bonded to the polyahl backbone to form products having molecular weights between those of the starting materials.  The carbonate backbone in the non-ionic surfactants can be degraded by bases, strong acids or biodegradation.  Accordingly, they will be degraded naturally and will not persist in the environment.     32,739A-F

Abstract: A method of operating a glass furnace especially for vitrification of ecologically hazardous waste materials such as asbestos or asbestos-containing demolition material, sewage sludge, varnish mud, ashes, filtering dust and the like and relates to the operation of a furnace with molten glass topped by a batch layer which contains the waste materials.  The batch layer is fed from the outside into the interior of the furnace, and the required heat energy is produced by means of heating installations in the glass melting furnace.  The molten glass produced from waste materials and admixtures is drawn from the furnace through an outlet.  The method is characterized specifically by producing on the surface of the molten glass a liquid layer of gall composed of alkaline salts, which, by drawing off as desired, is kept at a thickness layer range that corresponds to the respective furnace/operating conditions and which keeps the batch layer on top of the molten metal at a preferred thickness layer range that corresponds respectively to the furnace operating conditions by means of a controlled feeding and distribution of the appropriately composed mixture.

Abstract: Abstract A bilayer oxide film which comprises a preferably porous layer containing aluminum oxide and a non-porous layer comprising an oxide of a valve metal, e.g. tantalum. The layers are integral.  The film is produced by forming a coating of aluminum or an anodizable aluminum alloy on a valve metal (or alloy), anodizing the resulting structure in an electrolyte (preferably one capable of converting the aluminum (or alloy) to a porous oxide film) in the presence of an adhesion-reducing agent (e.g. fluoride ions) that makes the resulting anodized bilayer film easily detachable from the remaining valve metal.  The bilayer film is then detached from the valve metal, e.g. by adhering a flexible plastic film to the bilayer and using the film to peel off the bilayer from the valve metal. The resulting bilayer can be used for a variety of purposes, e.g. as a vapour or oxygen barrier, or as a coating containing magnetic particles used to make a magnetic recording medium.

Title: Recovery of scandium, yttrium and lanthanides from titanium ore
Inventor: FEULING ROBERT J
IPC: C01F17/224
Filed: 1990-08-02
Abstract: ABSTRACT OF THE INVENTION         This is  a process  for extracting scandium from titanium ore.   It  utilizes  feeding  titanium  ore  to a fluidized  bed  chlorinator  at  about 1000°C to produce a vaporous (generally titanium and  possibly iron chlorides) phase and a solid residue and recovering scandium from the solid residue.  Surprisingly,  despite the  relatively low sublimation temperature  of scandium chloride the very low level of scandium present in titanium  ore is concentrated in the  residue (rather  than going  with the vapor phase, where it  would not  be concentrated),  making recovery of scandium  from  the  titanium  ore  economically feasible. Generally, the process can  be part  of the  production of titanium metal  or titanium  oxide, whereby  scandium is a byproduct  of   titanium  production.     Preferably,  the recovery is performed by leaching the residue with aqueous acid (e.g. HCl) to  produce a  scandium-containing aqueous solution, followed by contacting the aqueous solution with a  polyalkyl  phosphate-containing   organic   phase,  the polyalkyl  phosphate  (e.g. tributyl phosphate) extracting scandium into  the  organic  phase,  followed  by scandium precipitation  by   an  ammonium  addition  to  produce  a scandium hydroxide precipitate and  the scandium hydroxide is calcined,  whereby scandium  is recovered  as an oxide. The residue generally also  contains yttrium  and lanthan-ides,  and   the  yttrium  and  lanthanides  can  also  be recovered from the  residue  as  a  part  of  the scandium recovery process.  The recovering of the scandium chloride from the residue can also  be  performed  by  leaching the residue  with  alcohol  (preferably methanol) to produce a 55,390 scandium-containing   alcohol   solution   (the  remaining residue  can  then  be  recycled to the chlorinator).  The leaching with  alcohol can  be followed  by contacting the alcohol solution  with oxalic acid to precipitate oxalates of scandium, thorium, and lanthanides.

Filed: 1990-09-05
Abstract: CATHETER PARTICULARLY USEFUL FOR INDUCING LABOR AND/OR FOR THE APPLICATION OF A PHARMACEUTICAL     SUBSTANCE TO THE CERVIX OF THE UTERUS       ABSTRACT OF THE DISCLOSURE           Artificial ripening of the unfavorable cervix was attempted in 69 patients by a newly designed double balloon catheter, placed in the cervix for 12 hours.          The balloons, each inflated to 40 ml, covered the internal and external cervical os, with the catheter's opening located between them, in the endocervical canal. The study was carried out in three phses.  In the first phase, 22 term pregnant women received intracervical PGE2 gel through the catheter with two inflated balloons confining the gel to the cervix. The second phase consisted of a double blind randomized controlled study, where, through the double balloon catheter, ten women received  PGE2 gel and another ten were given placebo gel.  The third phase consisted of an open study of inserting the catheter alone, without PGE2, and inflation of the balloons in 27 patients.  A substantial mean increase in the Bishop Score was noted in all these phases.
