Abstract: A multi-store, mechanically-actuated launcher is disclosed. Negator springs ut constant pressure on sequentially-stack stores inside a launch container and an electro-mechanical gate releases one store after another upon initiation of an electrial impulse from the transporting vehicle.

Abstract: A detection system for indicating the presence of motorized equipment in a esignated area having an acoustic sensor, a seismic sensor and an acoustic signal transmitter. The seismic sensor output, processed to discriminate against vibrations of short duration, is fed along with the acoustic sensor output, to an "ANDing" circuit which gates the acoustic transmitter. The acoustic sensor output is passed to the transmitter only during coincidence of seismic and acoustic detection.

Abstract: A deep ocean recoverable, tethered acoustic sensor system launchable from aircraft or ship. Upon water entry, the system separates into an upper flotation module containing a receiver/transmitter, antenna and inflatable bag, and a lower flotation module containing an expandable hydrophone array, transmission cable, flotation chamber, cable disconnect means, radio transmitter and antenna, and a flashing beacon light. The lower flotation module also includes a releasable anchor assembly containing a tethering cable. Recovery of the lower flotation module is accomplished by actuation of the cable disconnect means either by a preset timer means contained within the flotation module or by remote electrical command; upon cable disconnect, the anchor assembly and upper flotation module are discarded, and the lower flotation module floats to the surface for recovery.
