    • An ignition coil for an internal combustion engine has a rod-shaped magnetic core, which collaborates with a cushioning element in the axial direction. The magnetic core and the cushioning element are furthermore inserted into a secondary coil shell. Moreover, the coil shell has an ignition coil housing, which is filled at least partially with an epoxy resin. In order to avoid that the epoxy resin gets into the gap between the coating and the magnetic core, the cushioning element is developed as a sealing element at the same time. At the same time, the secondary coil shell has a coating on its inner wall for the accommodation of radial stresses. The ignition coil thus designed is developed to be relatively compact, and has good thermomechanical properties.
    • 用于内燃机的点火线圈具有杆状磁芯,其与轴向的缓冲元件协作。 磁芯和缓冲元件进一步插入到次级线圈壳中。 此外,线圈壳体具有至少部分填充有环氧树脂的点火线圈壳体。 为了避免环氧树脂进入涂层和磁芯之间的间隙,缓冲元件同时被显影为密封元件。 同时,次级线圈壳体在其内壁上具有用于适应径向应力的涂层。 这样设计的点火线圈被开发成相对紧凑,并且具有良好的热机械性能。

    • Polycrystalline semiconductor rods are converted to dislocation-free monocrystal rods by positioning a polycrystalline rod within a crucible-free zone melt environment with a seed crystal attached to one end thereof, generating a melt zone at the juncture of the seed crystal and the polycrystalline rod, controllably moving the melt zone away from the juncture and through the polycrystalline rod to a select point thereon, uniformly supporting the cone-shaped lower portion of the rod being processed so as to prevent oscillations and the like at the juncture of the rod in the seed crystal and controllably moving the melt zone from the select point to the remainder of the rod. A uniform support is preferably provided by an axially movable funnel-shaped casing which is attached to the seed crystal holding member and which, when moved into its operating position, is filled with a self-adjusting oscillation or vibration dampening means, such as molten metal, metal spheroids, quartz particles, sand, etc.

    • A nuclear reactor installation includes a pressurized-water coolant reactor vessel and a concrete biological shield surrounding this vessel. The shield forms a space between it and the vessel large enough to permit rapid escape of the pressurized-water coolant therefrom in the event the vessel ruptures. Struts extend radially between the vessel and shield for a distance permitting normal radial thermal movement of the vessel, while containing the vessel in the event it ruptures, the struts being interspaced from each other to permit rapid escape of the pressurized-water coolant from the space between the shield and the vessel.
    • 核反应堆装置包括加压水冷却剂反应堆容器和围绕该容器的混凝土生物屏蔽。 盾构件与容器之间形成足够大的空间,以便在容器破裂的情况下允许加压水冷却剂快速逸出。 支柱在容器和护罩之间径向延伸一段距离,允许容器的正常径向热运动,同时在容器破裂的同时容纳容器,支柱彼此间隔开以允许加压水冷却剂从空间快速逸出 在盾牌和船只之间。
