Patent CA-2474357-A1 (CA)
Inventor: VAN GANSWIJK JAN WILLEM
IPC: D06L1/00
Filed: 2002-12-04
Abstract: The present invention provides a method for the removal of stains from articles, especially fabric, using densified carbon dioxide. More particularly the invention is concerned with a method of dry cleaning an article comprising the successive steps of (a) contacting the article with a fluid dry cleaning composition containing densified carbon dioxide at a temperature between -20 and 60 ~C and a pressure between 1 and 100 MPa, so as to allow stains to dissolve and/or to disperse into the fluid dry cleaning composition and (b) separating the article and the fluid dry cleaning composition; wherein the fluid dry cleaning composition comprises an ionic surfactant in a concentration of between 0.01 and 15% by weight of the carbon dioxide and wherein during step a) at least 10%, preferably at least 30% of said ionic surfactant is present in an undissolved solid form. It was surprisingly discovered that the use of an ionic surfactant, e.g. a surfactant that contains a lipophilic alkyl residue and an amine, sulphate, phosphate and/or carboxylate residue, produces exceptionally good cleaning results if said surfactant is employed in an amount that exceeds its maximum solubility in the densified carbon dioxide composition and provided said surfactant is present during the cleaning operation in the form of undissolved solid particles.

Abstract: A thin metallic ferromagnetic alloy ribbon is annealed by continuously transporting it through an oven in order to induce specific magnetic characteristics and in order to remove a production-inherent longitudinal curvature of the ribbon. While the heat-treatment occurs, the ribbon is guid ed by a channel in a substantially straight annealing fixture. The channel is characterized by slight curvatures along portions of its length, in particul ar where the ribbon enters into the annealing oven. The curved channel provides an improved thermal contact between the ribbon and the heat reservoir. As a consequence the process can be conducted at particularly high annealing spee ds without degrading the desired characteristics.

Abstract: A anti-copy programme signal is provided. Copies of the anti-copy video pulses made on a video recorder experience reduced quality and interference in playback making them unpleasant to watch. The uncopied signal can be viewed without any material effect on picture quality. The signal comprises a pulse (28) added to each line (6) of the signal throughout both the visible picture region and throughout the vertical blanking region (12), as well as a first modulated wave-form (34) added to the vertical synchronisation pulses (16) of the signal and a second modulated wave-form (36) added to several lines (6) of the picture signal before the vertical blanking section (12). The presence of all three of these features together has been found to be provide a surprising accumulative effectiveness in causing interference in the reproduction of the modified video signal during playback of the copied video signal, that is greater than the effectiveness provided by the different features taken separately.
