Abstract: The present invention relates to a chemical for chelation of metal ions, which are at least bivalent, contained in water and/or water enclosed objects and separation/recovering of formed chelate; the structural formula of which is formula (I) where R in at least one of the positions shown is comprised of a group in the form of a straight or branched hydrocarbon chain having from 9 to 20 carbon atoms, and where appropriate 1-2 hetero atoms, and which is missing in other position(s); and where X in shown positions is in a group in the form of —COOH or its salt; and wherein the chemical can be a racemate, a mixture of enantiomers, or pure enantiomers or where R is missing in all four positions shown X in at least one position is —COOR, —CONHR or —CH2OR or —COR or —CH2OCOR or —CH2OCONHR; and where X in the remaining positions shown is comprised of a group in the form of —COOH or its salt; and wherein the chemical can be a racemate, a mixture of enantiomers, or pure enantiomers.

Abstract: The present invention provides methods for decreasing amounts of metal ions in liquid materials and in porous solid materials surrounded by a liquid, by utilization of sequestering agents that form complexes with said metal ions as well as methods for removing and optionally recovering said metal ions from the complexes. Further, there are provided novel sequestering agents and compositions comprising sequestering agents of the present disclosure.

Abstract: A method and system for image blending is disclosed. A destination image is received (100), the destination image including an image portion to be replaced and having characteristics associated with the identified image portion. A source image is also received (130). An image portion of the source image to be inserted into the destination image is identified (140). Where necessary, parameters of the image portion to be inserted are transformed to match those of the image portion to be replaced (150). The image portion to be inserted is then blended into the destination image in dependence on the image portion to be replaced and its associated characteristics (160). A video generation system using these features is also disclosed.
