20080215753 | Use of End-to-End Availability Calculations when Establishing a Connection - A method establishes a connection between a source node and a sing node of a communication network. One or several additional nodes represent nodes of the connection in addition to the source node and the sink node. An end-to-end availability of the connection is determined from one respective availability value of at least the additional node/s of the connection and each individual connection between two respective nodes of the connection. | 09-04-2008 |
20100097953 | ESTIMATION OF BANDWIDTH REQUIREMENTS IN A COMMUNICATIONS NETWORK WITH ACCESS CONTROLS - In one aspect, a method for estimating the bandwidth requirements for a transmission between an input node and an output node of a network with access controls is provided. According to the method, with respect to a time period, the sum of the value of the average bandwidth of the traffic that has been transmitted between the nodes during the time period and the weighted value of the accumulated bandwidth of the declined reservation requests is calculated. An efficient, approximate determination of the traffic matrix of the network and thus an optimal new definition of the limits for the access controls is permitted. This provides particular advantages in terms of efficiency and resources for applications in networks with a dynamic adaptation of the access controls to modified traffic situations. | 04-22-2010 |
20110116372 | NETWORK ACCESS CONTROL USING AN ADDITIONAL TRAFFIC CLASS IN A COMMUNICATION NETWORK - The aim of the invention is to provide a method, network control unit and a communication network for optimising the traffic in a communication network that is configured from network components, these entities permitting a degradation of service quality caused by the non-availability of network components to be at least temporarily averted. The solution to said aim is provided by a method for network access control in a communication network configured from network components, said method comprising the following steps: a) introduction of an additional traffic class to supplement a non-prioritising traffic class, more particularly a best effort class, and a traffic class offering a quality of service; b) configuration of a predeterminable bandwidth for the transmission of traffic in the additional traffic class; c) positioning of the additional traffic class above the non-prioritising traffic class and below or on the same level as the traffic class offering a quality of service; and d) authorisation of the use of the predeterminable bandwidth for the transmission of traffic in the additional traffic class for a predeterminable time period. | 05-19-2011 |

20080317893 | INTEGRATED SYSTEM FOR PRODUCING COMPOSITES - An integrated system for production of composites includes at least one polyurethane unit with a mixing head for mixing a polyol component and an isocyanate component, at least one plasticizing and injection unit, which is suitable for the melting and subsequent injection of a thermoplastic material, and one clamping unit to receive at least one mold. The plasticizing and injection unit and the polyurethane unit can each introduce material to be processed into a mold cavity within the clamping unit. In order to implement a unitary strategy of control and regulation and a unitary approach to operation of this type of integrated system apparatus, a single central control unit and at least one common supply device are provided, with the central control unit being connected at least with the at least one supply device. The at least one common supply device acts at least on both the polyurethane unit and the plasticizing and injection unit. | 12-25-2008 |
20090065973 | APPARATUS AND METHOD FOR MANUFACTURING MULTI-COMPONENT PLASTIC MOLDED PARTS - In a method of making multi-component plastic molded parts, using an apparatus which includes two outer platens with first half-molds, and a middle platen with second half-molds interacting with the first half-molds such as to define cavities in two parting planes for injection of a plastic melt and/or a PUR mixture, one of the first and second half-molds can move in increments relative to the other one of the first and second half-molds, thereby forming different cavities in the parting planes from cycle to cycle. In a first cycle preforms are produced in respective cavities and then held in one of the first and second half-molds as the other one of the first and second half-molds moves in increments. Further components can then be injected into cavities formed in the parting planes from cycle to cycle, while another process step can be executed from cycle to cycle in free half-molds. | 03-12-2009 |
20090102086 | METHOD FOR PRODUCING A COATED THERMOPLASTIC MATERIAL - In a method for producing a coated thermoplastic material, thermoplastic material is fed into a twin-screw extruder to produce a homogenous melt as the thermoplastic material is advanced. While the melt is in plastic state an adhesion promoter for a coating material to be applied later or a small amount of a coating material to be applied later as adhesion promoter is added to the melt which is then transferred to an injection mold and allowed to cure to form a thermoplastic body. The thermoplastic body is then coated with the coating material. | 04-23-2009 |
20090184436 | METHOD AND APPARATUS FOR MAKING A COMPOSITE, IN PARTICULAR COMPRISING AN INJECTION-MOLDED PART WITH A POLYURETHANE COATING - In a method for producing a composite, a carrier component is placed into an opened cavity of a mold. The mold is then closed to a predetermined position, thereby creating an cavity of a first expanded size. To improve venting, a vacuum is generated in the expanded cavity before filling the expanded cavity with a flooding material. A compression step is then executed either at the same time as flooding material is introduced or following the introduction of the flooding material. | 07-23-2009 |
20090218726 | DEVICE AND METHOD FOR PRODUCING MULTICOMPONENT PLASTIC PARTS - A device for producing a plastic part that has a plurality of components includes a closing unit for receiving at least one mold in which a thermoplastic molded body can be shaped or positioned, and at least one polyurethane unit for introducing a polyurethane material into a larger cavity comprising the thermoplastic molded body. At least one additional polyurethane unit is provided for introducing an additional polyurethane material having different product properties into a same or a different, larger cavity. As an alternative, the at least one polyurethane unit can be adapted for an additional polyurethane material having different product properties for introduction into the same or a different, larger cavity. | 09-03-2009 |
20090243148 | METHOD FOR PRODUCING A COATED COMPOSITE COMPONENT - In a method for producing a coated composite component, an injection-molded part is produced in a first cycle by introducing a melt into the cavity of a first mold. A polyurethane layer is then applied to the cavity surface of an open polyurethane mold half. The mold half with the injection molded part produced in the first cycle is associated with the polyurethane mold half, and the so formed second mold is closed. The polyurethane layer is pressed or embossed onto the injection-molded part in the second mold, and the coated injection-molded part is removed once the second mold has been opened. | 10-01-2009 |
