20100206128 | METHOD AND DEVICE FOR REMOVAL OF ELEMENTS RESOLVED IN A METAL MELT - Method for removal of elements from a metal melt in a container, which melt contains a base metal and elements of undesirable constituents, in which the metal melt is heated to a level maintaining the content melted. The metal melt is heated to a level causing vaporization of an element to be removed, but under the level providing gas pressure for the base metal. The container with the metal melt is brought under a reduced pressure in at least one compartment in which the temperature is maintained under the vaporization level of the element to be removed. A device for the removal of elements from metal melts, with a container ( | 08-19-2010 |
20110006052 | METHOD AND DEVICE FOR HEATING A FLUID - Method for heating a fluid, in particular a fluid which is not electrical conductive, where a rotor body ( | 01-13-2011 |
20110007600 | DEVICE FOR ADDING FLUID TO A LIQUID - Device for adding a fluid to a liquid, for example of gas and/or particles to liquid metal. A rotor is rotated immersed in the liquid, comprising a hollow rotational body | 01-13-2011 |
20110197670 | METHOD AND APPARATUS FOR MEASURING METAL PORTION IN DROSS - Method and apparatus for determination of portion of pure metal in dross from a dross source, whereby the metal portion in the dross is determined by measuring the dross density and calculating the metal portion in accordance with the formula m%=k−ρ+a, where m% is percentage pure metal, ρ is the dross density and k and a are empirical constants. In accordance with the invention, the apparatus comprises a closed container ( | 08-18-2011 |

20130033978 | Source Alive Route Injection - Multiple redundant sources for a datastream can be established in a network, where the redundant sources are configured with the same source address. One of the redundant sources provides the datastream to a receiver of a multicast group. If the redundant source fails, another redundant source can be used in its place, ensuring the receiver continues to receive the datastream. A routing element coupled to a redundant source monitors the redundant source for failure and informs the rest of the network of the status of the coupled redundant source. The routing element can inform other routing elements of the status by advertising or withdrawing a route that reaches the coupled redundant source, which the other routing elements can use to update their routing tables. | 02-07-2013 |

20110286470 | SYSTEM AND METHOD FOR PROVIDING MULTICAST DELIVERY IN A NETWORK ENVIRONMENT - A method is provided in one example and includes receiving signaling data associated with a request for a multicast channel, the request includes an Internet protocol version 6 (IPv6) source and an IPv6 group address. The method may also include identifying an Internet protocol version 4 (IPv4) source and an IPv4 group address to be mapped to the IPv6 source and the IPv6 group address. The signaling data can be converted from a first protocol to a second protocol. The converted signaling data can be communicated to a network element. In more particular embodiments, the network element is an IP edge router configured to join the multicast channel and stream data in response to receiving the converted signaling data. The IP edge router can be configured to perform an encapsulation operation to transport IPv6 multicast packets within an IPv4 multicast channel. | 11-24-2011 |

20130036307 | AUTHENTICATION OF CACHE DNS SERVER RESPONSES - A response to a Domain Name System (DNS) query can be protected with authentication information to be used by a host that originated the query. In one example, a DNS server is not among servers that can be authenticated by the Domain Name System Security Extensions (DNSSEC). The DNS server generates a public-private key pair and uses the private key for signing DNS resolutions. The corresponding public key can be distributed to hosts that will communicate with the DNS server. In various implementations, the public key is distributed by the DNS server and/or routers or as part of a neighbor discovery interaction. In one example, the public key is distributed in certificate path advertisements of the IPv6 Secure Neighbor Discovery Protocol (SEND) protocol. | 02-07-2013 |
20130188638 | Multicast Source Registration - A method, in accordance with particular embodiments, includes receiving an interest solicitation message advertising an availability of data from at least one source of a plurality of sources. The solicitation message comprises a source identifier indentifying the at least one source and a group identifier identifying at least one group. The method also includes sending a null message to a rendezvous node. The null message comprises the source identifier and the group identifier. The method additionally includes receiving, via the rendezvous node, a join message indicating that at least one endpoint has requested to join the at least one group identified by the group identifier. The method further includes sending a start message to the at least one source. The start message indicates that at least one endpoint has requested to join the group. The method also includes, receiving a first portion of the data after sending the start message. | 07-25-2013 |

20140269412 | ON-DEMAND BOOT STRAP ROUTER SOURCE ANNOUNCEMENTS - In one embodiment, a node in a communication network receives a request for messages of a particular group, determines a rendezvous point, and transmits the request to the rendezvous point to cause the rendezvous point to return a source-message indicating a source-node of the particular group. The node further creates a path from itself to the source-node and receives messages of the particular group according to the path. | 09-18-2014 |
