Abstract: An approach is provided for performing cloud based computer network security services. Security policies are established for each of a number of subscribers. The subscribers are provided access to the security services via a common network cloud managed by the service provider. The security services are administered according to a multi-tenancy format, which enables the subscribers' data communications to be separately processed. The security services include network firewalling and filtering of content originating from or destined to one or more networks associated with the subscribers.

In one particular exemplary embodiment, the technique may be realized as a method for maintaining secure network connections. The method may comprise detecting a change of address associated with a first network element. The method may also comprise updating at least one first security configuration at the first network element. The method may further comprise transmitting at least one secure message from the first network element to a second network element, wherein the at least one secure message comprises information associated with the change of address. And the method may comprise updating at least one second security configuration at the second network element based at least in part on the at least one secure message.

Abstract: A query statement, issued to a local database server, is re-written. The query references at least one of a first or a second object. The first object is remote with respect to the local database server, for accessing a first materialized view that is local or remote with respect to the local database server. The second object is local with respect to the local database server, to access a second materialized view that is remote with respect to the local database server. Rewriting the query can include dynamically tracking a staleness state associated with one or more of the materialized views.

Abstract: XQuery queries that include functions that operate on dynamically typed XML data are rewritten into compilable SQL constructs. XML data that is dynamically typed is XML data for which a specific XML data type cannot be determined at compile time and in fact may vary. In general, XQuery queries are rewritten into SQL queries that use SQL constructs in lieu of XQuery constructs. The SQL constructs include an “SQL polymorphic function” that is defined or recognized by a database system as valid syntax for an SQL query. The rewritten query applies the XML data to the SQL polymorphic function, but the XML data has been typed as XMLType, a data type recognized by SQL standards.

Abstract: In processing web material, the material is passed through a guiding arrangement which has a plurality of guide elements. In order to enable removing the guide element for repair without disturbing the web material, each of the guide elements is provided with a lifting arrangement which is concentric to the guide element and is movable from one angular position withdrawn from the path of the elongated material engaging the guide element to a second position lifting the elongated material off of the guide element so that the guide element can be axially withdrawn from the machine.

Abstract: Method and device for producing perforated nonwovens by hydrodynamic needling. A nonwoven with a basically clean hole structure on a drum with plastic elevations can be produced by energy-rich water jets. Depending on the thickness of the fibers used in the nonwoven, however, certain fibers can nevertheless be stretched transversely across a hole. In order to avoid or eliminate this, the perforated nonwoven is subjected to singeing flames after drying.

Abstract: A method of the invention relates to treating a textile base material for thermobonding interlining, the material being constituted by a woven fabric or a weft knit that includes texturized synthetic threads, in particular air jet texturized threads, which form loops on a top face that is to receive spots of glue, and on an opposite, bottom face. The method consists in subjecting said textile base material, prior to applying spots of glue thereto, to emerizing or equivalent pre-treatment on its bottom face and to pre-treatment on its top face for reducing the height of the loops, e.g. singeing or heat treatment by radiation or by contact. Preferably, the textile base material is initially subjected to emerizing or equivalent pre-treatment on its bottom face, and subsequently to singeing pre-treatment on its top face.

Abstract: A singeing machine, especially for the flame treatment of carpets made in the tufting process, with a burner unit (3) and disposed downstream of the burner unit (3) a smooth roller (14) which has a moistened surface (15), and which smooth roller (14) is cooled, wherein the smooth roller (14) is so strongly cooled that its surface (15) is below the dew point.

Abstract: A singeing device (V) for the gassing of circular goods (1), for instance circular knitted textile goods, having a singe burner (3) and a cloth guide (W) in order to obtain uniform gassing. The guidance of the goods (W) is developed so as to result in flat sides (a) of the circular goods (1) which extend substantially parallel to each other and rounded transition sides (b), and the singe burner (3) gasses the circular goods (1) both on the flat sides (a) and on the transition sides (b).

Abstract: A burner unit for the singeing of flat textile structures and the like, in particular a burner unit for singeing machines having a combustion chamber and ramp stones forming one or more singe slits, the combustion chamber being fed from a gaseous mixture chamber via preferably two or more parallel burner slits. A ramp stone is arranged adjustably movable for changing the singe slit and/or the combustion chamber.

Abstract: A battery separator fabric comprising a nonwoven fibrous web of thermoplastic fibers having top and bottom surface fibers and inner fibers. The surfaces of the top and bottom surface fibers of the fibrous web are seared and fused together to form film-like surfaces having pores, while the surface fibers and inner fibers of the web remain substantially unaffected. Searing and fusing of the surface fibers are accomplished by simultaneously applying heat to the top and bottom surfaces of the fibrous web so as to sear the surfaces of the thermoplastic fibers, and pressure to ensure that the seared fibers make contact with each other to secure themselves together. As the seared fibers make contact with each other, film-like surfaces are formed with pores being created in the surfaces. The pores are created because a majority of spaces remain between the surface fibers.

Abstract: Tubular textile fabric passes through a singeing apparatus preferably vertically upwardly. A guide path including a circular spreader guides the tubular fabric past gas operated singeing nozzles which are position adjustable in parallel to the longitudinal travel direction and radially thereto. The circular spreader forms a conical zone in the tubular fabric and the singeing nozzles are located around the conical zone so that an axial position adjustment of the nozzles changes the spacing between the nozzles and the fabric and a radial adjustment of the nozzles centers the nozzles relative to the fabric. The conical zone may taper in a direction opposite to the travel direction or in the travel direction of the fabric. The taper and its direction is determined by the diameter and the location of fabric guide rings forming part of the spreader. Cooling devices are located downstream of the singeing nozzles as viewed in the travel direction of the fabric.

Abstract: A machine for flame processing textile fabric webs (27), especially a singeing machine, is equipped with a burner unit (35) which comprises a combustion chamber terminating in a singeing slit, connected to a gas mixing chamber by a mixture feed slot (7).To save energy, the width of the working flame should be adjustable continuously and with low operating cost, whereby in particular provision should be made for automatically adjusting the flame width to the width of the fabric web (27) being processed. For this purpose, the burner unit (35) is provided with one or two flexible sealing strips (13) for the mixture feed slot, said strips being insertable from one or both ends of the burner unit, each of said strips further having its outer end wound on a winding body (33), rotatable for adjusting the inner ends of sealing strips (13).

To achieve a significant uniformity of the singeing flame in a longitudinal direction, the mixture distributing rail is enclosed between two guide strips respectively defining the outer longitudinal side of the burner slots, with the guide strips being clamped together with the mixture distributing rail, as a package, between the two substantially U-shaped profile members.
