Abstract: A computerized method of populating a database composed of rows with applicability fields and parameter fields in a data structure, and of retrieving the data, such that the database may be used to yield relevant results with a minimum of data entries. In a first step, the method defines a hierarchy of applicability fields to suit a particular business model as well as the associated univocal retrieval process. In a second step, the method substitutes unknown applicability fields with a USUB. In a third step, the method prompts the input of appropriate parameter field values for the rows of applicability fields, including those having one or more USUBs. A retrieval method retrieves the data in the data structure. The invention thus enables the population and data retrieval from a database structure such that the database is useful to yield relevant results with a minimum of data entries.

Abstract: Rotating sleeves having a body for receiving a yarn sleeve. The body has a side extension forming a flank piece. The flank piece is deformable such that a transverse dimension, for example, the greatest radial transverse dimension, of the body is reduced. The flank piece is generally plate-shaped with opposite edges forming the side edge of the body. Since the flank piece with the yarn sleeve is deformable, it reduces the transverse dimension of the body and thereby allows for yarn sleeves with small diameters to be slipped on easily.

Abstract: A coupling device allows for the rapid releasable connection of harness cords to lifting cords on weaving machines. A first coupler is connected to lifting cords and a second coupler is connected to harness cords. An intermediate coupler is removable connected to the first and second couplers. The intermediate coupler allows for quick and easy, manual or automatic, coupling and decoupling of the first and second elements. The second coupling elements and the intermediate elements are adapted so that only the connection therebetween is breakable when pulling forces are exerted thereon.
