    • A gyratory compactor apparatus (10) is provided for interacting with a sample (50) within a generally cylindrical mold (600). Such an apparatus (10) comprises a frame (100) defining an axis (150) and an offsetable (400) engaged frame (100) for engaging one end of the mold (600). The offsetable member (400) is displaceable from the axis (150) and is concurrently movable in an orbital motion thereabout. A pressure ram (200) is movable along the axis (150) and a mold-­engaging device (700) is engaged with the frame (100) for receiving the mold (600) such that the mold and frame axes (620, 150) are coaxial. The pressure ram (200) is axially movable within the mold (600) to apply a compaction pressure on the sample (50), and thereby maintains a portion of the mold at a gyration point (650) along the frame axis (150). The mold-engaging device (700) axially moves the mold (600) into engagement with the offsetable member (400). A securing device (720, 850) engaged with the offsetable member (400) and movable therewith reversibly engages the mold (600) to secure the mold (600) to the offsetable member (400) as the secured end is moved in the orbital motion by the offsetable member (400). The mold (600) is thereby gyrated and dynamically maintained at a gyration angle (640). Associated apparatuses, devices, and methods are also provided.
    • 提供回转式压实机装置(10),用于与大致圆柱形模具(600)内的样品(50)相互作用。 这种装置(10)包括限定用于接合模具(600)的一端的轴线(150)和可偏移(400)接合框架(100)的框架(100)。 可偏移构件(400)可从轴线(150)移位,并且可以在其周围的轨道运动中同时移动。 压力冲头(200)可沿轴线(150)移动,并且模具接合装置(700)与框架(100)接合以接收模具(600),使得模具和框架轴线(620,150) 是同轴的。 压力柱(200)可在模具(600)内轴向移动,以对样品(50)施加压实压力,从而将模具的一部分沿框架轴线(150)保持在回转点(650)。 模具接合装置(700)使模具(600)轴向移动成与可偏移构件(400)接合。 与可偏移构件(400)接合并且可移动的固定装置(720,850)可逆地接合模具(600),以在固定端在轨道运动中移动时将模具(600)固定到可偏移构件(400) 通过可偏移构件(400)。 因此,模具(600)被旋转并动态地保持在回转角(640)。 还提供了相关的装置,装置和方法。

    • Mechanical arrangements with primary application to single-acting, multiple-piston, Stirling-cycle machines providing a dramatic reduction in mechanical complexity and production cost. Two specific new machines are disclosed in detail, a single-acting, two-piston "ducted axle" machine and a quasi double-acting, four-piston, "drum cam" machine. A power level control subsystem inherent in the ducted axle machine permits engine output to vary from maximum positive through zero to maximum negative under full load conditions by means of the simple rotation of a single moving part. New thermodynamic working fluids are disclosed which have a higher dynamic heat transfer coefficient than either hydrogen or helium and are both chemically inert and easily liquefied. A different power level control subsystem for Stirling-cycle prime movers based on the thermophysical properties of these fluids greatly simplifies changing the average system working pressure. A new construction of the Stirling regenerator employs the anisotropic properties of materials such as pyrolytic graphite to achieve superior performance. Advantageous specific applications of copper matrix composites, manganesecopper alloys, and structural ceramics are disclosed.
