摘要： An improved facility for supporting the main landing gear assembly and the nose wheel assembly of a commercial jetliner is quickly adjustable so as to be able to accommodate different aircraft models. The facility includes a nose wheel lift platform system that includes an elongated pit, a support platform that is supported in the pit and is adapted to support an aircraft's nose wheel assembly, and a number of spacer blocks for covering portions of the elongated pit that are not covered by the support platform. The support platform is mounted on a trolley which is equipped to move the support platform up or down as well as lengthwise along the pit. The spacer blocks are slidable along the upper opening of the pit. By moving the trolley beneath a spacer block and engaging the spacer block with the support platform, an operator can move the spacer blocks with the support platform. Accordingly, an operator wishing to reposition the support platform to accommodate a certain type of aircraft may quickly and conveniently reposition the spacer blocks to expose the intended new location of the support platform, and cover the position that was left exposed, prior to moving the support platform to its new location.
摘要翻译： 用于支撑商用喷气式客机的主起落架组件和前轮组件的改进设备可以快速调节，以便能够容纳不同的飞机型号。 该设施包括前轮升降平台系统，其包括细长的凹坑，支撑在凹坑中并且适于支撑飞机前轮组件的支撑平台，以及用于覆盖细长凹坑的部分的多个间隔块 不支持平台覆盖。 支撑平台安装在手推车上，该手推车装备有可沿着凹坑向上或向下以及纵向移动支撑平台。 间隔块可沿着坑的上部开口滑动。 通过将手推车移动到间隔块下方并将间隔块与支撑平台接合，操作者可以利用支撑平台移动间隔块。 因此，希望重新定位支撑平台以容纳某种类型的飞行器的操作者可以在移动支撑件之前快速且方便地重新定位间隔块以暴露支撑平台的预期新位置并且覆盖被暴露的位置 平台到其新的位置。

摘要： A single-use, disposable, elastomeric patient valve has a pair of one-way check valves disposed in the cross-piece portion thereof to create a barrier against patient infection. The check valves prevent contamination by a first patient of the reusable demand valve portion as he or she exhales into the patient valve and prevents the inhalation of possibly infected materials into the lungs, via the sampling chamber and associated tubing coupling same to the patient valve.
