Patent CA-2504944-C (CA)
Inventor: WERKL DIETMAR
IPC: B01L3/00

Granted: 2010-01-12
Abstract: The invention describes processes for producing a film of a hydrophilic polymer on the inner surfaces of a fluidic component in which firstly the inner surfaces of the fluidic component are subjected to a physicochemical treatment, in particular a plasma treatment, subsequently the inner surfaces are brought into contact with a solution of the hydrophilic polymer, afterwards the polymer solution is replaced by a gaseous medium in such a manner that firstly the inner surfaces remain wetted with part of the polymer solution and finally a film of the hydrophilic polymer remains on the inner surfaces of the fluidic component by removing the solvent. The hydrophilic polymer that is used in this case has a surface wettability for aqueous solutions which is higher than the surface wettability of the inner surfaces of the fluidic component itself. In addition the invention describes fluidic components and systems as well as analytical systems on the inner surfaces of which a film of a hydrophilic polymer is at least partly present.

Abstract: Systems and apparatuses for authentication and/or access authorization in a communications network. A source node (10, 12, 14, 16, 18) initiates a request for network services, such as session establishment, database access, or application access. Known network resources, authorized user, and/or source information are stored in a database at a network portal (50) along with access policy rules that can be device and/or user dependent. A source node (10, 12, 14, 16, 18) can construct a packet header including a user identifier indicating the user originating the request, and/or a source identifier indicating the hardware from which the request is originated. At least one of these identifiers are included with a synchronization packet for transmission to a destination node. An appliance or firewall (70) in the communications network receives, authenticates, and determines whether resource access is authorized before releasing the packet to its intended destination.

Abstract: Provided is a process of obtaining 1,1,1,3,3,3-hexafluoro-2-propanol ("HFIP") from a composition comprising an HFIP hydrolyzable precursor. The HFIP  hydrolyzable precursor is a compound, other than sevoflurane itself, that has an intact 1,1,1,3,3,3-hexafluoroisopropoxy moiety[(CF3)2CHO~], and contains one or more moieties susceptible to acidic hydrolysis, such that HFIP is released upon such treatment. The process is useful, among other things, for recovering HFIP from waste streams associated with the synthesis of the inhalation anesthetic, fluoromethyl 2,2,2-trifluoro-1-(trifluoromethyl)ethyl ether ("sevoflurane"). The process includes heating the composition with a strong protic acid to a temperature effective to hydrolyze at least some of the HFIP hydrolyzable precursor to HFIP, and then isolating the HFIP from the heated composition.

Abstract: Il s'agit d'un dispositif qui permet de séparer un fluide non newtonien, par exemple une matière synthétique en fusion qui circule dans un passage (1, 21) et qui présente une viscosité conditionnée par le débit et qui diminue vers l'extérieur dans une section d'écoulement à travers un embranchement de passage en T (T) déviant et divisant le débit de liquide. Dans une première version du dispositif, avant la fin du passage d'approvisionnement (1), une cloison (11) est installée dans l'embranchement du passage (T), qui divise le contre-courant venant du passage d'alimentation (1) en deux moitiés. La position angulaire de la cloison (11) donne un réglage adapté à la répartition des éléments visqueux par action différentielle du liquide dans le passage d'alimentation (1). Dans une seconde version du dispositif, dans l'embranchement de passage (T), un déflecteur (23) est installé, de manière que, essentiellement, l'élément central (visqueux) du liquide venant du passage d'alimentation (21), avant sa déviation dans les passages de refoulement (22a, 22b), soit divisé en deux éléments. La déviation de ces passages fait que les deux éléments circulent de préférence diamétralement l'un vers l'autre, dans la zone devant les passages de refoulement (22a, 22b).

Abstract: A windshield removal assembly, method and blade for same, with the thin metal blade having a unique delta-shape. The blade connects at its narrowed shank portion to the shaft of a reciprocating power tool. The blade has front and rear ends, the front end being substantially straight and wider than the blade rear end. The blade has substantially straight side edges which narrow from the front end to the rear end to about the width of the shaft. Arc portions are formed between the front end and each side edge of the blade. The top edge of the blade forms a non--sharpened top edge on the front end and arc portions, while the bottom edge of the blade forms a sharpened bottom cutting edge which extends across the front end of the blade and along at least half of the arc portions. The blade has sufficient rigidity to cut the urethane bed when reciprocated, and sufficient lateral flexibility to conform to the curved surface of the windshield when pressed thereagainst. The large arc portions, combined with the sharpened cutting edge extending substantially around the arc portions, improve cutting in a generally continuous lateral movement, especially around corners. The straight side edges preferably join the shank at a reduced angle to strengthen the blade, allowing it to be made in greater lengths without breakage.

Abstract: An object of the present invention is to provide a novel system whereby an enteral nutrient or an enriched liquid food can be solidified so that it can be easily administered within a short period of time without liquefying in the body to thereby lighten a care-giver 's burden in tube feeding such as gastrostomic feeding. As the results of studies, it is found out that such a nutrient or an enriched liquid food can be quickly thickened or solidified at a temperature of 40°C or below by using a starch adhesive, which contains as the main component sodium iota-carrageenan, sodium kappa-carrageenan, sodium lambda-carrageenan or a mixture thereof, without dissolving the starch adhesive by heating. Further, it was confirmed that it is an administration method almost free from water liberation when the solidified product was administered from a syringe, thus the present invention was completed. That is, the use of the above carrageenan as a starch adhesive (a semi-solidifying agent) makes it possible to produce the desired semi-solidified enteral nutrient as described above.
