Abstract: Embodiments are disclosed for providing network management and application services for a telecommunications network. In an embodiment, data associated with a network entity in the telecommunication network may be received from a provider-specific data source, and the received data may include one or more data attribute values. The telecommunications network may be represented by a network graph containing vertices and edges, and each vertex may correspond to a respective network entity having a respective entity type. The plurality of edges in the network graph connected to the first vertex may be updated based on a linking rule that specifies a relationship between network entities having respective entity types, and a walk associated with the first vertex may be identified. The identified walk may then be dynamically executed from an intermediate starting vertex to generate one or more output entities.

Abstract: Systems and methods are disclosed for managing network elements in a telecommunications network. In an embodiment, a real-time processing module processes stream data representing one or more network elements in the telecommunications network to build a real-time view. The real-time processing module stores the real-time view in a view database. A batch processing module processes snapshot data representing all the network elements in the telecommunications network to build a batch view. The batch processing module processes the snapshot data slower than the real-time processing module processes the stream data. The batch processing module saves the batch view in the view database. A presentation module presents a selected view from the view database for display.

Abstract: Compositions and methods for cleaning polymer processing equipment. The compositions contain at least one or more thermoplastic materials or resins and a cross-linking agent such as an organic peroxide. The compositions may also include fillers, blowing agents and lubricants.

Abstract: An apparatus for injection molding two compatible polymeric materials, in which two or more plasticizing zones on a screw are used to simultaneously or sequentially plasticize the two materials into a common accumulation space through separate pathways. The charge comprising multiple layers of material is then injected into a closed mold by means of forward axial motion of the screw with respect to its enclosing barrel. Once inside the mold, the first material forms a skin layer, totally or partially surrounding the other material. In this way a part having a plurality of material properties may be produced in a single operation.

Abstract: Apparatus and methods of applying text, graphics, or other coatings to the surface of injection molded plastic parts by injecting a pigmented ink or other liquid through pores in the mold wall during the molding cycle so that parts are molded and printed in one operation.

Abstract: Methods and devices for cleaning the screw and barrel of a reciprocating screw injection molding machine using a purging/cleaning compound and a non-return valve that can be held open during the purging/cleaning cycle to allow bi-directional flow of the purging/cleaning compound.

Abstract: An apparatus for injection molding two compatible polymeric materials, in which two substantially coaxial extrusion screws are used to plasticize the two materials into a common accumulation space. The charge comprising multiple layers of material is then injected into a closed mold by means of forward axial motion of the outer screw with respect to its enclosing barrel. Once inside the mold, the first material forms a skin layer totally or partially surrounding the other material. In this way a part having a plurality of material properties may be produced in a single operation.
