Abstract: Apparatus for filter cleaning including a filter element surface (12) to be cleaned, and a cleaning head (10), characterized by a controller (16) operative to move the cleaning head (10) with respect to the filter element surface (12) in a spiral scanning trajectory in such a way that a relative path of the cleaning head (10) with respect to the filter element surface (12) results in a trajectory that fully, or partially covers the filter element surface (12) and is produced by moving the filter element surface (12) in any combination of the following motions: a) one or more circular or semi-circular motions, b) one or more linear motions; while moving the cleaning head (10) in any combination of the following motions: c) one or more circular or semi-circular motions, d) one or more linear motions.

Abstract: A method of extending an existing product taxonomy for an inventory of products. The existing product taxonomy can include pages having a hierarchical tree structure. The method can include determining a first set of keywords. The first set of keywords can be a prediction of keywords searched above a predetermined threshold during a predetermined time period of one or more external search engines. The method also can include generating dynamic product groups based on the first set of keywords. The method further can include generating a relation graph of the dynamic product groups. The relation graph can include relation links between the dynamic product groups. The method also can include linking the dynamic product groups to pages in the existing product taxonomy to generate an extended product taxonomy. The extended product taxonomy can include the existing product taxonomy, the dynamic product groups, and the relation links of the relation graph between the dynamic product groups.

Abstract: Provided is a filtration cassette having a rigid body configured for externally supporting a filtration media disposed thereover and having at least one filtering surface configured with a flow path facilitating filtered fluid flow from a space extending between the filtration media and the filtering surface, and extending towards an outlet terminal. Also provided is a filtration segment including such a filtration cassette and where the filtration media is a filtration thread tensionally coiled over the filtration cassette at a multi-layered and tight configuration. Further provided are a plurality of such filtration segments which are configured into a disk-type assembly forming a filtration unit for a filtering system.

Abstract: An innovative fiber-wound filtration system for use with spiral-trajectory type cleaning systems.
