    Abstract: A method and apparatus for remotely opening a manual valve of a gas cylinder from a remote location. The gas cylinder is first connected to a purge system which is purged of oxygen and pressurized with an inert gas to a pressure near that of the gas cylinder. The manual valve is then engaged with a pneumatic stepper mechanism. Pneumatic fluid is supplied to the pneumatic stepper mechanism to rotate the manual valve a predetermined stepped increment. The step of supplying pneumatic fluid to the pneumatic stepper mechanism is repeated, after pausing to let the system settle, to rotate the manual valve another stepped increment. The steps of rotating and pausing are repeated until the manual valve is opened. The purge system is then vented to atmosphere through a diffuser. Both the pneumatic stepper mechanism and the purge system are fully operable from the remote location. The pneumatic stepper mechanism includes a ratchet assembly and an attachment assembly connecting the ratchet assembly to the manual valve. The ratchet assembly includes a gear rotatable about all axis, a drive arm pivotable about the axis, a pneumatic cylinder attached to the drive bar, and a driving pawl pivotably attached to the drive bar and operably engaging the gear. The drive bar is reciprocally pivoted about the axis as the pneumatic cylinder extends and retracts and the driving pawl rotates the gear in only one direction as the drive bar pivots.

    Abstract translation: 一种从远程位置远程打开气瓶手动阀的方法和装置。 气瓶首先连接到吹扫系统，吹扫系统被清除氧气并用惰性气体加压到靠近气瓶的压力。 然后手动阀与气动步进机构接合。 将气动流体供给到气动步进机构，以使手动阀旋转预定的阶梯式增量。 重复向气动步进机构供给气动流体的步骤，在暂停以使系统稳定后，旋转手动阀另一阶梯式增量。 重复旋转和暂停的步骤，直到手动阀打开。 吹扫系统然后通过扩散器排放到大气中。 气动步进机构和吹扫系统都可以从远程位置完全操作。 气动步进机构包括棘轮组件和将棘轮组件连接到手动阀的附接组件。 棘轮组件包括可围绕所有轴线旋转的齿轮，可围绕轴线枢转的驱动臂，连接到驱动杆的气动缸，以及可枢转地连接到驱动杆并可操作地接合齿轮的驱动爪。 当气缸延伸和缩回时，驱动杆相对于轴线往复枢转，并且当驱动杆枢转时，驱动爪仅在一个方向上旋转齿轮。

    Abstract: Aluminum and aluminum alloy melts are purified by removing entrained gaseous impurities and solid particulate impurities, primarily aluminum oxides, by bubbling a non-corrosive intimate mixture of sulfur hexafluoride in an inert gas. Magnesium levels, if present, are not significantly reduced. The process is reliable and the gas mixture safe for aluminum purifying operations and procedures.

    Abstract: A method of removing sterilization gas from a load disposed in a chamber. In accordance with the method, the chamber is evacuated to a subatmospheric pressure. A diffusion gas comprising helium is provided. An amount of the diffusion gas is introduced into the chamber effective to create a superatmospheric diffusion pressure in the chamber. The diffusion gas is allowed to diffuse throughout the chamber to displace sterilization gas from the load. The chamber is evacuated to remove portions of the diffusion gas and the sterilization gas from the chamber.
