  • Patent number: 9911568
    Abstract: A metal jet x-ray tube is proposed, that is affected less than conventional tubes by the problem of the power density at the point of incidence of the electron beam on the anode component. To this end, the metal jet x-ray tube provides a metal jet as an anode component that is so thin that this metal jet only partly decelerates an electron beam incident thereon. Moreover, the metal jet of the anode component is at least embedded or dissolved in a single second material that passes electrons relatively well and is heat absorbing.

  • Patent number: 8706189
    Abstract: A combined PET/MRI device is disclosed. In at least one embodiment, the PET/MRI device includes an MRI unit for exciting nuclear spins in an examination volume and for receiving signals generated by the excitation in the examination volume, and a PET unit with a detector which surrounds the examination volume at least in part and is used for detecting radiation emanating from the examination volume, with, firstly, damping of the radiation emitted by the examination volume and, secondly, undesired interactions with electromagnetic fields of the MRI unit on the components of the PET/MRI device arranged between the examination volume and the detector being avoided due to the material properties and/or structural design of the components. Corresponding components such as, for example, patient couches, bearing or support apparatuses and local coils, are both MRI and PET compatible.

  • Patent number: 7554927
    Abstract: There is described a Session Initiation Protocol (SIP) network entity for operating in a communications channel between a first SIP end point and a second SIP end point in a communication network. The first SIP end point has available a first set of communication features and the second SIP end point has available a second set of communication features, including at least one communication feature, for example Music on Hold, that is unavailable to the first SIP end point. The network entity acts as a client application for the first SIP end point and as a server application for the second SIP end point and is arranged to exchange signaling information with the SIP end points to enable the second SIP end point to utilize the at least one communication feature during communications with the first SIP end point.

  • Patent number: 5079837
    Abstract: A repair lining for a heat exchanger tube includes a sleeve having ends. A tubular basic body is disposed in the sleeve and has ends protruding beyond the ends of the sleeve. One of the ends of the basic body has a top part being supported on the sleeve and the other of the ends of the basic body has a thread formed thereon. A nut is disposed on the thread for bracing the repair lining in the heat exchanger tube. At least one clamping ring is disposed on one of the ends of the basic body between the sleeve and the top part, and at least one clamping ring is disposed on the other of the ends of the basic body between the sleeve and the nut. The clamping rings have a conical shape in an initial relaxed condition being changed into a flattened shape with an enlarged diameter by relative motion between the basic body and the sleeve.
