摘要： An improved closed-end manometer which overcomes the problems associated with prior U-tube manometer devices. The invention comprises a small bore tube which is transparent or translucent at least along the measuring portion and which may be of tapered or cylindrical bore, a permanent closure at one end of the tube, a relatively small indicating slug formed of a suitable liquid, a measuring scale to note the position of the liquid slug, and a measured quantity of a selected gas between the closure and the nearest end of the liquid slug. The open end of the tube is connected to the vessel or system whose pressure is to be measured or monitored. One feature of the present invention is its ability to provide quantitative pressure indications over a wide range of pressures, or the invention may be calibrated to provide increased sensitivity over a relatively short measuring range. Another feature of the invention is its ability to provide accurate pressure measurements regardless of the instrument's orientation. Furthermore, the invention may be readily formed in small sizes which renders it inexpensive to make and feasible for one-time, expendable use, for example with disposeable medical products.
摘要翻译：改进的封闭式压力计克服了与以前的U型管压力计装置相关的问题。本发明包括至少沿着测量部分是透明或半透明的并且可以是锥形或圆柱形孔的小孔管，在管的一端处的永久闭合件，由合适的液体形成的相对较小的指示塞子，测量刻度以记录液体塞的位置，以及在封闭件和液体塞的最近端之间的所选气体的测量量。管的开口端连接到要测量或监测其压力的容器或系统。本发明的一个特征是其在宽范围的压力下提供定量压力指示的能力，或者本发明可被校准以在相对短的测量范围内提供增加的灵敏度。本发明的另一个特征是能够提供精确的压力测量，而不管仪器的取向如何。此外，本发明可以容易地以小尺寸形成，这使得其制造便宜并且可用于一次性，一次性使用，例如与可分散的医疗产品。

摘要： In a space shuttle, payloads are individually temperature controlled by means of a liquid control loop in heat exchange relationship with both the payload and a radiator or shuttle cold plate. The liquid pump is driven at a variable speed to control the heat transferred between the load and the radiator or cold plate, and the motor may be reversed to by-pass the radiator through check valves. The radiator includes heat pipes seated in elongated, high thermal conductivity extrusions and retained therein by elongated springs. The motor is a brushless DC motor isolated from the pump by a magnetic clutch and thermal isolator. The motor is driven by a digital circuit which provides a single pulse to each set of windings during each energizing time frame. The width of that pulse is modulated to provide for speed control. Pulse width modulation is by means of a one-shot, the pulse duration of which is controlled by a speed control signal.
