Abstract: To reduce the rotational power, an apparatus with a rotational body that is rotationally driven in a fluid-filled housing a rotational directing body is provided between the rotational body and the housing, which is rotatably supported coaxially with respect to the rotational body. The rotational directing body is configured such that in operation it rotates at an intermediate rotational frequency in comparison to the housing and the rotational body. The apparatus is particularly an X-ray radiator having a cathode and anode that are mounted in a vacuum tube in a spatially fixed manner in relation to the tube, the vacuum tube being rotationally driven as a rotational body in a coolant housing.

Abstract: An improved x-ray tube is disclosed that eliminates the use of a fluid-filled outer housing for cooling tube components. The present x-ray tube includes a cathode housing in which is disposed a cathode assembly having a filament for producing electrons, and an anode housing in which is disposed a rotary anode for receiving electrons produced by the filament. An adapter plate is sized to hermetically receive therein the cathode assembly and the anode housing, thereby forming a unitary vacuum enclosure and tube housing. The improved x-ray tube is cooled by a combination of air and fluid cooling to reduce the buildup of damaging heat within the vacuum enclosure. The features of the present invention are preferably directed to an anode grounded-type x-ray tube, though other x-ray tube types may benefit therefrom.

Abstract: A system and method are proposed for cooling the anode of an X-ray tube. A bearing shaft associated with the anode has an associated single rotating seal there around, and contains a liquid metal. A primary liquid metal flow path is used to transfer heat from the anode, and a secondary liquid metal flow path is provided to seal the single rotating seal. Accordingly, the present invention provides an effective means for containing liquid metal in the bearing shaft of an anode assembly, and using the liquid metal to cool the anode of the X-ray tube.

Abstract: An X-ray diffraction device comprises a water-cooled X-ray tube which exhibits a line focus as well as, after rotation through 90.degree., a point focus. Contrary to customary X-ray tubes, the cooling water is not supplied via the housing (12) in which the X-ray tube is mounted, but the cooling water connections (52, 54) are provided directly on the X-ray tube at the same side of the robe where the high-voltage connector (16) is provided. As a result, rotation of the robe upon changing over from a line focus to a point focus is not hampered by cooling water connections inside the housing of the tube. An additional advantage of this method of supplying the cooling water resides in the fact that the robe base (56) can also be cooled via these ducts. The base would otherwise become inadmissibly hot due to the loss heat from the filament (60).

Abstract translation: X射线衍射装置包括水冷X射线管，其呈现线焦点，并且在旋转90°之后具有点聚焦。 与常规X射线管相反，冷却水不通过安装有X射线管的壳体（12）供应，但是冷却水连接（52,54）直接设置在X射线管上 设置高压连接器（16）的长袍的同一侧。 因此，从管线焦点转换到点聚焦时，长袍的旋转不会受到冷却管内部的水连接的阻碍。 提供冷却水的这种方法的另外的优点在于，长袍基座（56）也可以经由这些管道被冷却。 否则，由于来自细丝（60）的热量的损失，底座将变得不允许热。
