Abstract: Aqueous coating compositions include an anionic species-scavenging system. The scavenging system includes an aqueous dispersion of water-insoluble, weak base-functional polymer particles. The particles are polymerized from monomer including a weak base-functional monomer such as 2-(diethylamino)ethyl methacrylate or 2-(t-butylamino)-ethyl methacrylate. A two stage process may be employed to prepare the particles and 2-(dimethylamino)-ethyl methacrylate may be included only in the initial stage. Alternatively, a single stage process may be employed using 2-(t-butylamino)methacrylate. The system also includes a volatile base such as ammonia to maintain the pH of the composition above the pK a  of the weak base prior to and during application of the composition. As the volatile base is lost, the weak base is protonated and forms ion pairs with anionic species such as anionic surfactant. The compositions form coatings having good water resistance, and may be used as paints, paper coatings, caulking materials, adhesives, binders for non-woven products and for floor polishes and printing inks.

IPC: C02F1/64
Filed: 1988-01-25
Abstract: Method for continuous treatment of an aqueous solution containing certain ions to be removed. The aqueous solution containing the ions to be removed is first of all neutralised if it is acidic and then brought into contact with a metal salt (1) which is both very poorly soluble in water and which has a very high affinity for reacting with the ions to be removed to form another water-insoluble salt. This contact is brought about for a sufficient period of time to enable this other insoluble salt to form. This method is highly efficient and can be employed, for example, to remove chromium from aqueous effluents by employing barium carbonate as the salt which is very poorly soluble in water. <IMAGE>

Date Jun. 29, 1989.A device for taking samples of arterial blood with a view to its subsequent gasometric analysis comprises a main body forming a reservoir in which a free piston travels. Said piston isolates the blood from the air and cannot be manipulated by the operator. The device also includes a filter located at the end of the piston stroke which is permeable to air and impermeable to blood, allows the operator to observe the blood as it advances, and acts as a barrier to excessive blood flow, and a stopper which ulitmately seals the system and facilitates its tranport. In contrast to conventional invasive systems, this device, which does not need to be sterilized, makes it possible to obtain a blood sample which, after sampling, is only minimally contaminated with the ambient air, is available in a sufficient quantity, and is only slightly coagulable.

Abstract: Fibers of a biocompatible, biodegradable or non-biodegradable, synthetic polymer are provided, and are formed into a three-dimensional scaffold. The fibers of the scaffold may have a branched configuration extending outwardly from a central stem. The fibers provide sufficient surface area to permit attachment to the scaffold in vitro of an amount of cells effective to produce functional vascularized organ tissue in vivo. Fibers of the scaffold are spaced apart such that the maximum distance over which diffusion of nutrients and gases must occur through a mass of cells attached to the fibers is between 200 and 300 microns. The diffusion provides free exchange of nutrients, gases and waste to and from cells proliferating throughout the scaffold in an amount effective to maintain cell viability throughout the scaffold in the absence of vascularization. Cells derived from vascularized organ tissue are attached in vitro to the surface of the fibers uniformly throughout the scaffold and the cells are grown on the scaffold in a nutrient solution in vitro to form a cell-scaffold composition. Growth factors, compounds stimulating angiogenesis and immunomodulators may be provided in the cell-scaffold composition and the fibers may have a coating to enhance cell attachment. The cell-scaffold composition is implanted in a host at a location having adequate vascularization to allow growth of blood vessels into the cell-scaffold composition. Combinations of cell-scaffold compositions containing different cell populations may be implanted.

Abstract: Un élément non-réutilisable pour seringues comprend un corps de seringue (32) dont l'extrémité inférieure est fermée par une base (34) pourvue d'un cône (52) de réception d'une aiguille (44) et une tige (42) qui se termine par un piston (36) et qui glisse étroitement dans le corps de seringue. Un disque flexible (60) dont e diamètre est supérieur au diamètre interne du corps de seringue, ce qui fait que sa courbure entraîne une faible friction lors du déplacement de la tige dans un premier sens et une forte friction lors du déplacement de la tige dans l'autre sens, est monté dans la tige. Le sens de la courbure du disque peut s'inverser lorsque l'on guide le disque (60) dans la rainure (68). Afin d'empêcher l'élément pour seringues d'être réutilisé, une zone (66) de faible résistance à la rupture sous traction est formée sur la tige. Cette zone se casse sous une traction inférieure à la forte friction, mais supérieure à la faible friction. Le disque (60) peut être monté sur la tige et s'appuyer élastiquement contre le corps de seringue, ou peut être monté sur le corps de seringue et s'appuyer élastiquement contre la tige. La seringue comprend un cylindre dont une extrémité est fermée par une base (310) pourvue d'un ajutage (312) traversé par un canal (314); une tige qui se termine par un piston et qui glisse à l'intérieur du cylindre de la seringue; et une aiguille creuse (308) pourvue d'une base (324) et d'un conduit (326).
