Abstract: L'invention concerne un procédé de traitement d'un puits de pétrole ou de gaz, dans lequel on injecte, à partir du puits, une solution aqueuse d'un polymère dans le terrain environnant. Ce traitement peut avoir pour but, par exemple, la récupération assistée du pétrole ou le colmatage sélectif, destiné à réduire les venues d'eau dans les puits producteurs. Ce procédé se caractérise en ce que l'on injecte une solution obtenue par dispersion dans l'eau d'un microlatex stable et transparent, lui-même obtenu par un procédé dans lequel : a) on prépare une microémulsion stable et transparente du type eau dans l'huile en mélangeant (i) une phase aqueuse constituée par une solution aqueuse d'au moins un monomère vinylique hydrosoluble choisi dans le groupe formé par l'acrylamide, l'acide acrylique et un mélange d'acrylamide avec l'acide acrylique avec (ii) une phase huileuse constituée par une huile d'hydrocarbures et au moins un agent tensioactif, en présence éventuelle d'un co-tensioactif,la nature et les proportions des ingrédients ci-dessus étant choisies de façon à répondre à la double exigence suivante. .alpha.) la teneur en agent tensioactif de la phase huileuse est d'au moins 2% en poids, la phase aqueuse est présente en proportion de 1 à 50 parties en poids pour 99 à 50 parties en poids de la phase huileuse par rapport au poids total de ladite phase aqueuse et de ladite phase huileuse et le monomère vinylique hydrosoluble est présent en proportion de 5 à 55% en poids pour 95 à 45% en poids d'eau, et .beta.) le mélange des deux phases constitue une microémulsion stable et transparente; b) on soumet la microémulsion obtenue à l'étape (a) à des conditions de polymérisation de manière à produire un microlatex stable et transparent d'un polymère ou d'un copolymère ayant une masse moléculaire d'au moins 500 000; et c) on recueille le microlatex stable, transparent résultant.

The precipitated protein is formed into a slurry and enzymatically hydrolyzed to produce a predetermined number of available amino end groups as measured by fluorescamine reaction on said protein.  This enables the production of an enzymatically hydrolyzed protein isolate having a predetermined level of hydrolysis with improved flavor and suspension characteristics in beverages.

Abstract: "CONVERTIBLE SEAT"                       ABSTRACT OF THE DISCLOSURE     Convertible aircraft passenger seat can be quickly changed from a three-seating position configuration to a more spa-cious two-seating position configuration without the use of tools.          Such a seat permits the seating capacity of an aircraft to be al-tered to match the expected passenger load in different classes, such as tourist and business class.  In the three-position configuration, a pair of relatively narrow width armrests, which may contain recline lock control cables or audio cables, project vertically out of the lower seat cushion on either side of the center seating position but are pivotally mounted so that they will overlie the center position in a generally horizontal fashion in the two-position configuration, thus adding several inches of width to the adjacent end seating positions.  Each of a pair of elongated back cushion side extensions has fastening means on one side thereof by which it may be alterna-tively attached to one side of a relatively narrow center position back cushion in the three-position configuration or to an inboard side of one of the end position back cushions in the two-position configuration.  In the latter configuration, the relatively narrow center back cushion is folded forward where it conceals the later-ally folded narrow armrests and forms a wide armrest and/or cock-tail table between the two wide seats.
