  • Publication number: 20140202952
    Abstract: The present invention relates to a method of producing multilayer anodized aluminium oxide nano-porous membrane and the membrane produced thereof. Further the invention relates to the nano-porous multi-layer membrane for filtration application. The three layered membrane of the present invention avoids sticking of solute components on the surface obviating the problem of coagulation. This membrane imparts anti coagulation capability wherein in-spite of sticking of the solute component on the surface of the membrane appropriate passage is still available for liquid/small solutes to pass beneath the said stuck solute component to enhance effective surface area for filtration obviating the problem associated with coagulation.

  • Publication number: 20140202950
    Abstract: The present invention relates to an anodized aluminum oxide tubular nano-porous membrane array module and method of manufacture thereof. Further the invention relates to a system of such modules. The tubular membrane modules of the present invention can be cascaded to up-scale the surface area of the overall system rather than scaling the surface area of a single tubular membrane. Thus the volume density that is the available surface area for filtration per unit volume of the system is substantially enhanced without compromising on mechanical stability to withstand the pressure differential defines by the end use application.

  • Publication number: 20140202868
    Abstract: A system and method for preparation of nano-porous membrane using anodized aluminium oxide and the membrane/film/thin lamina produced thereof. The system comprises a template forming device that comprises of two rolls provided with one or plurality of projections wherein the Al sheet is passed through the said rolls that are rotatable in opposite direction with respect to each other wherein in operation as the Al sheet is passed through the said rolls, the said projections of the rolls punch depressions to the predetermined depth in the said sheet wherein the depth of the depression is governed by the height of the projections. A method for preparation of anodized aluminum oxide nano-porous membrane comprising electro polishing of Al substrate; first step anodization; chemical etching of alumina; second stage anodization; etching Al for separation of alumina and barrier layer removal or voltage pulse detachment for barrier layer removal and detachment of membrane from Al substrate.

  • Patent number: 8270711
    Abstract: Method and apparatus for machine recognition of an object depicted in an image. The image is filtered to help isolate the object. The machine segments the object to determine relationships between one or more object segments. The relationships between the one or more object segments are then compared to known characteristics to facilitate machine recognition of the object.
