    Abstract: A ring seal is engaged with a liquid metal bearing assembly and operates to contain metal fluid lubricant leaking through the primary compression seals of a liquid metal bearing to prevent the fluid from entering the high voltage space within the x-ray tube and causing high voltage instability. The ring seal engages the existing configuration for the bearing assembly without deforming the bearing, including effects of thermal expansion and inertial body forces, thus maintaining the tight tolerances for the proper operation of the component parts of the bearing structure. The ring seal retains the leaking liquid metal within the ring seal regardless of the operating state and/or condition of the bearing assembly, such as during operating conditions. i.e., rotation of the bearing assembly or gantry, and non-operating conditions, e.g., shipping and stand-by, and regardless of the corresponding pressures and their locations exerted on the ring seal by the liquid metal.

    Abstract: A structure and associated process for joining dissimilar materials to form various components of an x-ray tube is illustrated that utilizes one or more intermediate or interfacial filler material members positioned between the primary welding or mating surfaces of the base material components to be joined. The use of the interfacial or intermediate filler material preserves the multiple benefits of friction welding, as well as enabling the joining of highly dissimilar material components, decreasing the required joining temperature, and providing increased microstructural control of the resulting well or joint.

    Abstract: A mounting structure for mounting an x-ray tube on a CT rotatable gantry is disclosed. The mounting structure includes base plates that are boltable to the CT rotatable gantry and have bearing strut connections formed thereon. Spherical bearing struts are provided in the mounting structure to mechanically couple the x-ray tube to the base plates, with the spherical bearing struts each having a first end secured in a respective bearing strut connection of the x-ray tube casing and a second end secured in a respective bearing strut connection of the base plates. The spherical bearing struts constrain a gantry-load direction displacement of the x-ray tube and enable rotation and displacement of the x-ray tube around at least one axis of rotation or in one direction other than a gantry load direction, so as to accommodate thermal displacements in the x-ray tube created during operation thereof.
