Abstract: An improved stopcock valve, including a valve body, the valve body having at least one inlet port and at least one outlet port, the valve body having an internal cavity in communication with the at least one inlet port and the at least one outlet port and, a rotatable interference body having a through-bore therein, the rotatable body having an external surface, the through-bore having a first opening to the surface and a second opening to the surface, the interference body positioned within the internal cavity of the valve body, the external surface including a first tapered groove in communication with the first opening and a second tapered groove in communication with the second opening, the grooves arranged to be in communication with the at least one inlet port and the at least one outlet port upon rotation of the body.

Abstract: A probe deployment mechanism of a coordinate measuring machine provides for extending and retracting a probe. The probe is displaceable with respect to the actuator body connected to the measuring machine. A locator coupling secures the probe to the actuator body at the extended position for taking measurements. A drive coupled to the probe displaces the probe between the extended and retracted positions but at the extended position, the drive is releasable from the probe for kinetically isolating the locator coupling.
