A locking mechanism for moveable control fins extending from the surface of a missile. The locking mechanism includes a pin extending thru the outer surface of the missile into an opening provided in the movable fin. A link is pivotally connected between each of the pins and a slide member disposed internally of the missile and carried by a guide. The links are in a close to dead center position when the pins are extended into the openings in each of the fins. Upon a command signal from a controller, preparatory to missile launch, a restraining device holding the slide is removed and a spring commences movement of the slide toward a position which will take the links past their dead center position upon which additional springs which are loaded around each of the pins are activated to positively move the slide and extract the pins from the openings in the fins.

Missile fin locking mechanism

A low emission valve assembly for use with volatile fluids and incorporating a pair of independent inner and outer metal bellows mechanical seal assemblies with means to compensate for thermal expansion of a liquid between the seals and which means transmits product pressure within the valve to the seals, so that the inner seal floats with a near zero pressure differential from outside to inside. The compensating means can be a pressure responsive bellows arrangement or a pressure response diaphragm arrangement.
