Abstract: The devices are floating engageable means which may be a floating nut or a floating driver for use in hostile environment, such as space. The device includes a housing with a cross-shaped opening, each arm of the cross receiving a wing of a floating member. A spring between the base of the housing and the back of the floating member urges the wings against the top surface of the arms of the cross-shaped opening in the housing. The cross-shaped openings may have a rectangular configuration with a thread surface forming the top surface of the opening. This permits the floating member to maintain a lateral offset. Alternatively, the arms may have a triangular outline with the vertex forming the top surface of the arms. With this configuration, a force will be provided to center the floating member in the housing. The floating member terminates in a an outwardly facing taper guiding surface which tapers to the engaging means of the floating member. With this arrangement, off axis and off angle mating is possible.

Abstract: A positionable transducer array on a stationary platform proximate a layered site on the seabed coherently insonifies locations at the site with a signal having a selected power, resultant center frequency, beamwidth, bandwidth, shape and incident angle. A positionable receiver array on the platform captures the return signals. Sub-surface acoustical properties of the location are then predicted from the return signals and a calculation of the speed of sound in water at the site. Subsequent locations at the site are then interrogated and an interpolation is made of acoustical properties between locations to develop a model of the acoustical properties at the site.
Abstract: In a load transporting conveyor of the type which has a plurality of load confining compartments located thereon which are transported by the conveyor along a load transporting path, there is provided a load settling mechanism. The load settling mechanism includes a load support platform which forms a bottom wall of each compartment. Resilient suspension members support the bottom wall with respect to the conveyor such that it is free to vibrate with respect to the conveyor. A vibration activator mechanism is located along the load transporting path so as to engage successive load support platforms as they are transported along the load transporting path to cause the load support platform to vibrate to thereby vibrate any load which is located thereon to cause the load to settle into the load confining compartment.
