    • A sealing arrangement (36) for sealing a leakage gap between relatively moveable parts in a flow path between a region of high pressure (A) and a region of low pressure (B). The sealing arrangement comprises an annular sealing land (52) having a radially inner surface (54) and a radially outer surface (56) projecting from one of the said moveable parts and at least two brush seal elements (40,42). The brush seal elements (40,42) comprise a mass of bristles arranged in an annular shape, one end of the bristles being fixed (48), the other being free (46). The bristles are packed together in a layer and positioned one side of a backing member (44). At least one brush seal element is provided on the radially inner surface (54) of the sealing land and at least one brush seal element is provided on the radially outer surface (56) of the sealing land (52).
    • 一种密封装置,用于密封高压(A)区域和低压区域(B)之间的流动路径中相对运动部件之间的泄漏间隙。 密封装置包括具有径向内表面(54)和从所述可移动部件之一突出的径向外表面(56)的环形密封平台(52)和至少两个刷密封元件(40,42)。 刷密封元件(40,42)包括布置成环形的刷毛质量,刷毛的一端被固定(48),另一端是自由的(46)。 刷毛一起包装在层中并定位在背衬构件(44)的一侧。 至少一个刷密封元件设置在密封台肩的径向内表面(54)上,并且至少一个刷密封元件设置在密封台(52)的径向外表面(56)上。

    • A mechanism for permitting selective adjustment of the angular position of a head-mounted night vision device is provided. The mechanism comprises a housing positioned adjacent the night vision device. A shaft defining a longitudinal axis is at least partially positioned within or adjacent the housing. The shaft is rotatively coupled to the night vision device, wherein rotation of the shaft induces rotation of the night vision device. A moveable lever is coupled to the shaft for rotating the shaft. Means for selectively limiting rotation of the shaft are provided, wherein the means are moveable between a first position and a second position. In the first position the means permit rotation of the shaft and the optical device, and in the second position the means limit rotation of the shaft and the optical device.
    • 提供一种用于允许选择性地调节头戴式夜视装置的角位置的机构。 该机构包括邻近夜视装置定位的壳体。 限定纵向轴线的轴至少部分地定位在壳体内或邻近壳体。 轴可旋转地耦合到夜视装置,其中轴的旋转引起夜视装置的旋转。 可移动杆联接到轴以旋转轴。 提供了用于选择性地限制轴的旋转的装置,其中装置可在第一位置和第二位置之间移动。 在第一位置,该装置允许轴和光学装置的旋转,并且在第二位置,装置限制轴和光学装置的旋转。

    • An apparatus for manufacturing a ceramic device from tape (21) in a green state comprises a cylindrical rod (23) as a first forming element, a first clamping system (241) for fixing a first end of the tape (21) with respect to the cylindrical rod (23) and a first mechanism (20, 231) for winding the tape (21) around the cylindrical rod (23) to preform the tape (21). The apparatus further comprises a second forming element (33), a second clamping system (351, 352) for fixing at least one end of the pre-formed tape (21) with respect to the second forming element (33), and a second mechanism (331, 351) which winds the pre-formed tape (21) around the second forming element (33).
    • 用于从绿色状态的带(21)制造陶瓷器件的设备包括:作为第一成形元件的圆柱形杆(23),用于将带(21)的第一端相对于第一形成元件固定的第一夹紧系统(241) 所述圆柱形杆(23)和用于将所述带(21)围绕所述圆柱形杆(23)缠绕以预成型带(21)的第一机构(20,231)。 该装置还包括第二成形元件(33),用于相对于第二成形元件(33)固定预形成带(21)的至少一端的第二夹紧系统(351,352),以及第二 机构(331,351)围绕第二成形元件(33)缠绕预成形带(21)。
