Abstract: The invention belongs to the field of information system technology and more specifically in the area of electronic content management. The invention concerns method producing filtering systems of electronic documents that contain text in different languages, e.g. English, French, etc., as well as multimedia elements, e.g. digital images and/or digital video and/or digital excerpts of audio/speech. These documents can be semi-structured, i.e., they can exhibit structural features that are not to be found in non-digital documents, e.g. hyperlinks, or not. The method can be applied in the same way and provides the same results either to the filtering of electronic content in the Internet (World Wide Web, electronic mail, etc.) or in organizational computer networks (e.g. intranets), as well as in any other network that allows the transfer of multimedia and/or multilingual electronic content.

Abstract: Disclosed are antifoam emulsions useful in control of foam in aqueous foaming systems which comprise:(A) polydiorganosiloxane;(B) fine solid particles of inorganic oxide, bearing on the surface thereof a polydiorganosiloxane component; wherein the total amount of polydiorganosiloxane present in components (A) and (B) comprises 5 wt % to 60 wt % of the emulsion and the weight ratio of the total amount of polydiorganosiloxane present in components (A) and (B) to the amount of said inorganic oxide is 10:1 to 200:1;(C) an organic surfactant dispersing agent selected from the group consisting of non-ionic tetrafunctional block copolymers terminating in primary or secondary hydroxyl groups and mixtures thereof, which agent comprises 0.

Abstract: Microemulsions are provided in which the oil phase comprises a reaction product of an organosilicon compound having amino groups and an organosilicon compound having epoxy groups, wherein the reaction product has at least one amino group and two silicon-bond --OR groups. A method for making the microemulsions which comprises reacting the two organosilicon compounds sufficiently to allow the reaction of some of the amine groups with the epoxy groups, but avoiding the excessive crosslinking of the components and their application in the treatment of fibrous materials is also described.
