Abstract: A compressed air stream is separated in a double rectification column 8 having a higher pressure stage 10 and a lower pressure stage 12. The lower pressure stage 12 contains a low pressure drop liquid-vapour contact means 13 having a pressure drop of less than 400 Pa per theoretical stage, for example a structured packing, to effect mass transfer between ascending vapour and descending liquid. A product gaseous oxygen stream is withdrawn from the stage 12 through an outlet 36 and is warmed to about ambient temperature in the heat exchanger 6 in countercurrent flow relationship with the compressed air stream which is thereby cooled. Refrigeration for the process is created by expansion of part of the incoming air. By using a low pressure drop liquid-vapour contact means 13 in the lower pressure stage 12, the resulting operating pressure in the higher pressure stage is able to be lower than in a conventional process enabling the incoming air to be compressed to a lower pressure (for example a pressure in the range 5 to 6 bar). At such pressures, two expansion turbines 54 and 56 are used to enable the heat exchanger 6 to be operated efficiently.

Title: Process and tent- or sack-shaped body for removing toxic materials.
Inventor: BERG ALEXANDER
IPC: B08B15/02
Filed: 1990-11-22
Abstract: In a process for removing materials which contain or release toxic dust, in particular materials containing asbestos, in particular parts of buildings, the working area is enclosed by films, textile materials, paper or the like, which are impermeable to the toxic dusts. While the work is in progress, the enclosed working area is maintained under partial vacuum by persons in the working area. The films, textile materials or paper are then removed. The process is characterized in that a tent- or sack-shaped, closed body made of film, textile materials or paper, one wall of which has a slit, is erected in front of the materials to be removed. Alternatively, the edges of the slit are fixed in a dust-tight manner around a region to be decontaminated or renovated. On completion of the work, the edges are detached from the region to be decontaminated or renovated and joined together. The air is then pumped out of the shaped body, which collapses. The collapsed shaped body is then removed from the work site.

Abstract: Un appareil avec une structure simple et un procédé de moulage par extrusion permettent de maintenir un degré satisfaisant de fluidité du matériau de moulage dans une filière et d'augmenter dans une large mesure la productivité d'articles moulés ayant une épaisseur uniforme. A cet effet, on fait résonner pendant le moulage la filière pourvue d'un organe de réglage de l'ouverture d'extrusion. En outre, de préférence, afin d'assurer un écoulement uniforme du matériau de moulage à proximité d'une ouverture d'extrusion de la filière, où en général une stagnation de l'écoulement est la plus probable, l'organe de réglage de l'ouverture d'extrusion est assujetti à une partie de la filière qui forme l'ouverture d'extrusion, de sorte que seule cette partie de la filière résonne pendant le moulage. Dans un mode préférentiel de réalisation, afin d'obtenir une résonance efficace, la fréquence de résonance de l'organe de réglage de l'ouverture d'extrusion est égale à la fréquence de résonance de la filière et l'organe de réglage de l'ouverture d'extrusion est associé à la partie nodale de la résonance. En outre, l'ouverture d'extrusion de la filière coïncide avec la partie à boucle de résonance, c'est-à-dire, la partie où l'effet des vibrations est le plus fort, de façon à réduire la résistance par frottement entre le matériau de moulage et la surface à proximité de l'ouverture d'extrusion de la filière.

Abstract: Un signal de commande standard pour une machine à former des bandes continues est momentanément interrompu et remplacé par un signal ou plusieurs signaux perturbateurs appliqués à une, à un groupe ou à la totalité d'une série de cellules de commande de la machine à former des bandes. Une ou plusieurs cellules de commande sont activées par un ou des signaux perturbateurs alternants qui produisent une action correspondante dans la ou les cellules de commande. Le ou les signaux perturbateurs alternent à partir d'une position neutre de la cellule et sont sélectionnés pour réduire au minimum les effets moyens sur une période donnée. Les effets du signal ou des signaux alternants sur la bande apparaissent dans la région de la bande qui est affectée par la ou les cellules de comman, de sorte que la disposition et la réponse de la ou des cellules de commande peuvent être déterminées en surveillant la partie de la bande qui est formée alors que le ou les signaux alternants sont appliqués à la ou aux cellules de commande. La ou les dispositions et/ou la ou les réponses de la ou des cellules de commande sont obtenues en mettant en corrélation le ou les signaux perturbateurs et un signal de propriété de bandes ou un signal de profil obtenu surveillant la bande formée par la machine. Le ou les signaux perturbateurs sont définis par une séquence binaire pseudo-aléatoire avec des signaux multiples sélectionnés de manière à être statistiquement indépendants les uns des autres. Afin de s'assurer que la bande n'est pas perturbée au-delà des spécifications définies, l'amplitude du signal perturbateur est de préférence augmentée graduellement et ledit signal est arrêté individuellement pour chaque cellule de commande lorsqu'une amplitude utilisable est atteinte.

Title: Dental compositions and methods for treating teeth surfaces.
Inventor: FISCHER DAN E
IPC: A61K6/90
Filed: 1991-03-18
Abstract: The present invention discloses high viscosity sustained release dental compositions, such as tooth bleaching or fluoride compositions, for treating tooth surfaces. For maximum results, an improved dental tray having reservoirs for holding the dental composition adjacent the desired tooth surfaces is preferably used in combination with the sustained release dental composition. The sustained release dental compositions include a high carboxypolymethylene concentration which results in very high viscosity. The high level of carboxypolymethylene makes dilution of the dental compositions from saliva difficult and time consuming so that the compositions stay within the tray reservoirs, thereby providing sustained release. The concentrated carboxypolymethylene adds a unique tackiness to the dental composition which helps retain and seal the soft tray material against the patient's teeth.
