Abstract: The present invention provides a combined scale inhibitor and scale inhibiting device. The combined scale inhibitor contains organophosphorus filter materials, ceramic filter materials and polyphosphate filter materials. The organophosphorus filter materials are the granular filter materials of liquid organophosphorus scale and corrosion inhibitor while the said ceramic filter materials are the granular filter materials containing oxide ceramic powder. The said scale inhibiting device is comprised of a tank, a water inlet, a water outlet, an organophosphorus filter material layer, a ceramic filter material layer and a polyphosphate filter material layer in the said tank. The said organophosphorus filter material layer contains organophosphorus filter materials, which are the granular filter materials of liquid organophosphorus scale and corrosion inhibitor. The said ceramic filter material layer contains ceramic filter materials, which are the granular filter materials containing oxide ceramic powder.

Abstract: Methods, systems and articles of manufacture for browsing heterogeneous map data are described herein. A method embodiment includes displaying a plurality of homogeneous images, each image representing a geographic information system (GIS) dataset comprising one or more map assets an enabling browsing of GIS datasets and map assets using said displayed images independent of underlying data formats of said GIS datasets. A system embodiment includes a map data engine configured to receive a plurality of homogeneous images, each image representing a GIS dataset comprising one or more map assets, and a user interface configured to display said images and enable browsing of GIS datasets and map assets using said displayed images independent of underlying data formats of said GIS datasets.
