Also provided is a method of bleaching a substrate comprising applying the liquid bleaching composition to the substrate. Also provided is a method of treating a textile by contacting the textile with the liquid bleaching composition, whereby the complex catalyses bleaching of the textile by atmospheric oxygen after the treatment.Type: GrantFiled: April 1, 2002Date of Patent: November 25, 2003Assignee: Unilever Home & Personal Care USA, division of Conopco, Inc.Inventors: Ronald Hage, Simon Marinus Veerman

Patent number: 4941185Abstract: A method and apparatus for processing a first (e.g. half-tone) image constituted by a second (e.g. continuous tone) image convolved with a periodic (screen) function, to produce the second image is described. The invention is particularly suited to handling digitally represented half-tone images. The apparatus comprises a microcomputer (17) for determining digital data defining a frequency filter characteristic adapted to suppress the frequency or frequencies of the periodic function. A fast Fourier transform circuit (11) transforms the image data into the frequency domain and a multiplier (12) multiplies the transformed data by the frequency characteristic stored in a store (13). The resultant multiplied data is inversely transformed back into the image of spatial domain by a fast Fourier transform circuit (14) to generate the second image.Type: GrantFiled: October 6, 1988Date of Patent: July 10, 1990Assignee: Crosfield ElectronicsInventor: Alastair Reed
