    Abstract: A reagent dispensing valve particularly adapted for dispensing precise microfluidic quantities of fluids. The valve includes a valve portion and a solenoid actuator that are in fluid isolation from one another. The valve portion includes a plunger and seat combination and the actuator is substantially decoupled from the fluid path through the valve. The fluid path through the valve is substantially non-tortuous, thereby minimizing localized fluid pressure drops, and hence undesirable gaseous bubble precipitation within the fluid. The valve is also configured to substantially prevent bubble accumulation. The valve can further include a bubble trap for trapping and removing bubbles.

    Abstract: A micro-volume fluid injector in which the fluid does not contact the piezoelectric disk and is easy to make in very small sizes. A piezoelectric disk is removably secured to the plunger so as to overlie the diaphragm. An upper housing is secured to the upper surface of the intermediate housing sandwiching type disc so that when energized the central portion along with the diaphragm and plunger moves away from the orifice to permit fluid flow therethrough. The plunger is disposed within the orifice and close to the exterior portion of the orifice so that minimal space is provided for undesirable accumulation of fluid.

    Abstract: Apparatus for stowing and deploying stores from air and marine craft (FIG. 2) in which the stores 28 are stowed on a modular stowage structure, such as pallets 32, with releasable locking devices 10 securing the pallets to the craft. Further releasable locking devices 29 and restraining means 30 are arranged to secure the stores to cradles 14 on respective associated pallets. The pallets and cradles are adapted to permit, upon release of the respective further releasable locking devices 29, movement by the effect of gravity of the stores to effect deployment of the stores. The stowage structure may be mounted on a ramp on the deck of the craft or the pitch of the vessel may be adjusted to effect deployment. The structure may be releasably slung beneath a sub-surface craft and provided with a fiberglass casing to make it floatable.
