Patent number: 6326340Abstract: Biofilm and debris can be removed from the interior and exterior surfaces of small bore tubing by passing an aqueous cleaning solution of water, one or more surfactants and preferably a source of hydrogen peroxide, optionally including small inert solid particles, together with a gas under pressure, to create a turbulent flow within the tubing that loosens the biofilm and debris so that they can be flushed from the tubing. When the exterior surfaces of tubing are to be cleaned, the tubing is inserted in a sleeve fitted with an adaptor that provides a pressure-tight seal between the tubing and the sleeve.Type: GrantFiled: September 29, 1998Date of Patent: December 4, 2001Inventors: Mohamed Emam Labib, Ching-Yue Lai

Patent number: 6297209Abstract: Sequestering agents for use as a whitening and fabric strength enhancer for aqueous hypochlorite bleach compositions are provided. It was found that the sequesterants when used with hypochlorite in the presence of soluble heavy metal ions, particularly iron and manganese ions, provide significantly improved whitening and fabric protection. Most preferably, the sequesterants are selected from polyacrylic acid, a polyacrylic acid derivative, a copolymer of acrylic acid or methacrylic acid and a comonomer which is maleic acid or maleic anhydride and mixtures thereof.Type: GrantFiled: May 10, 1996Date of Patent: October 2, 2001Assignee: The Clorox CompanyInventors: Thomas W. Kaaret, William L. Smith

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
