Abstract: A hydraulic fluid reservoir for de-aerating a hydraulic fluid received therein. The hydraulic fluid reservoir is of a type including two chambers separated by an intermediate baffle with a central opening connecting the chambers. In the lower chamber, cyclonic flow may be used to separate the aerated fluid from the de-aerated or non-aerated fluid and may be assisted by an inverted velocity cone. In the upper chamber, there may be a second state nucleation device, such as a mesh screen, that assists in removing entrained gases from the fluid by providing points of for the gas to nucleate thereon or collect. Additionally, a distribution header may be located in the upper chamber that returns fluid from the upper chamber to the lower chamber via a connection of the header to the return port at an eductor.

Abstract: A tether for securing a variety of instruments. The tether may include a band sized to fit a human wrist, a lanyard formed as a continuous, closed loop, an interface connecting the lanyard to the band, and a lock. The lock may adjustably pinch the lanyard to form two sub-loops therefrom. By adjusting the location where the lock pinches the lanyard, the size of one sub-loop may be continuously increased or decreased, while the size of the other sub-loop may be simultaneously, continuously, and respectively decreased or increased. Accordingly, by adjusting the location where the lock pinches the lanyard, the size of the one sub-loop may continuously vary between a minimum size and a maximum size. In one embodiment, this minimum size may corresponding to an interior diameter within the one sub-loop of substantially zero.
