摘要： A motor, expander, compressor, or hydraulic device is formed with an oscillating rotating piston comprising a cylinder having an axis of rotation and end surfaces and defining an oscillating compression volume and an expansion volume. An axial sealing member separates the compression volume and the expansion volume, and seal members seal the end surfaces of the piston. Valves operate to close the compression volume and open the expansion volume at each oscillation of the piston. Means are provided for reversing the rotation of the cylinder at the end of a compression cycle of the piston. One or more pistons may be provided that contact other pistons along axial surfaces to form axial seal surfaces with rolling contacts that reduce friction energy losses.

摘要： An apparatus for irradiating a continuously flowing stream of fluid is diosed. The apparatus consists of a housing having a spherical cavity and a spherical moderator containing a radiation source positioned within the spherical cavity. The spherical moderator is of lesser diameter than the spherical cavity so as to define a spherical annular volume around the moderator. The housing includes fluid intake and output conduits which open onto the spherical cavity at diametrically opposite positions. Fluid flows through the cavity around the spherical moderator and is uniformly irradiated due to the 4.pi. radiation geometry. The irradiation source, for example a .sup.252 CF neutron source, is removable from the spherical moderator through a radial bore which extends outwardly to an opening on the outside of the housing. The radiation source may be routinely removed without interrupting the flow of fluid or breaching the containment of the fluid.
摘要翻译： 公开了一种用于照射连续流动的流体流的装置。 该装置由具有球形腔体和包含位于球形空腔内的辐射源的球形慢化器的壳体组成。 球形调节剂的直径小于球形腔，以便围绕调节剂限定球形环形体积。 壳体包括在直径相对的位置上打开到球形腔上的流体进入和输出导管。 流体围绕球形慢化剂流过空腔，并且由于4π辐射几何形状而被均匀地照射。 照射源，例如252CF中子源，可通过向外延伸到壳体外部的开口的径向孔从球形慢化器移除。 可以常规地去除辐射源而不中断流体流动或破坏流体的容纳物。
