    • A liquid natural gas filling system structured to store a cryogenic fluid at a low pressure and fill a use vessel at a high pressure. The filling system includes a first, low pressure vessel, at least one second, high pressure vessel, a plurality of conduits, each conduit in the plurality having a valve, extending between, and in fluid communication within the first, low pressure vessel and the at least one second, high pressure vessel, a pressure building means coupled to the at least one second, high pressure vessel and structured to raise the pressure of a cryogenic liquid within the at least one second, high pressure vessel, and an outlet nozzle structured to be coupled to a use vessel, the outlet nozzle coupled via the plurality of conduits to, and in fluid communication with, the first, low pressure vessel and the second, high pressure vessel. The filling system is structured so that a cryogenic liquid may be stored in the first, low pressure vessel at a low pressure. The cryogenic liquid at a low pressure may further be transferred to the at least one second, high pressure vessel via the plurality of conduits. The pressure of the cryogenic liquid at a low pressure in the at least one second, high pressure vessel may be increased to a high pressure by actuating the pressure building means. Thus, the cryogenic liquid at a high pressure in the at least one second, high pressure vessel may be transferred from the at least one second, high pressure vessel to a use vessel via the plurality of conduits and the nozzle.
    • 一种液体天然气填充系统,其构造为在低压下储存低温流体并以高压填充使用容器。 填充系统包括第一低压容器,至少一个第二高压容器,多个导管,多个导管中的每个管道具有阀,在第一低压容器内部和第二低压容器之间在流体连通中延伸, 至少一个第二高压容器,压力建筑装置,其耦合到所述至少一个第二高压容器并被构造成提高所述至少一个第二高压容器内的低温液体的压力,以及出口喷嘴结构 联接到使用容器,出口喷嘴通过多个管道连接到第一低压容器和第二高压容器中并与第一低压容器和第二高压容器流体连通。 填充系统的结构使得低温液体可以在低压下储存在第一低压容器中。 低压下的低温液体可以进一步经由多个导管传递至至少一个第二高压容器。 在至少一个第二高压容器中低压下的低温液体的压力可以通过致动压力建立装置而增加到高压。 因此,在至少一个第二高压容器中的高压下的低温液体可以经由多个导管和喷嘴从至少一个第二高压容器转移到使用容器。

    • A metrological instrument for measuring surface characteristics such as surface form of a component (300). The instrument includes a slideway (32) to cause relative movement between a surface sensing probe (84) and the component which allows the probe to traverse a surface of the component. A probe carriage (80) supports the probe to allow the probe to move as a body in a measurement direction relative to the carriage so as to follow a surface being sensed. An optical sensor (82) provides a signal indicative of the displacement of the probe relative to the probe carriage. A controller (83) acts in response to a signal from the optical sensor, to move the probe carriage so as to maintain the probe in an operational range. A further sensor (11) measures measurement of displacement of the probe in the measurement direction as it follows a surface during use of the instrument.
    • 用于测量表面特性(例如部件(300)的表面形式)的计量仪器。 该仪器包括滑道(32),以在表面感测探头(84)和允许探针穿过部件表面的部件之间产生相对运动。 探针支架(80)支撑探头以允许探针作为身体在相对于滑架的测量方向上移动,以便跟随被感测的表面。 光学传感器(82)提供指示探针相对于探针台架的位移的信号。 控制器(83)响应于来自光学传感器的信号而起作用以移动探针支架,以将探头保持在操作范围内。 另外的传感器(11)在使用仪器期间测量探头在测量方向上的位移测量。
