Abstract: An improvement in a subsea wellhead apparatus that includes the conventional plurality of strings of conduit suspended in a borehole penetrating subterranean formations below the bottom of a sea at which the wellhead apparatus will be placed and the conventional wellhead and accessories disposed above the bottom and the plurality of strings of conduit; the improvement comprising a first communications aperture communicating with a first annular space intermediate a desired pair of conduit strings; a sealed conduit that defines a sealed path of flow for flowing a fluid waste into the annulus intermediate the respective conduit strings; remotely operable high pressure control valves interposed in the conduit for controlling the flow of fluid between the annular spaces and a remote control for controlling the flow control valves so as to route the fluid waste to the first annular space and fractured formation communicating therewith.

Abstract: An erectable wing structure for a supersonic airframe that is stowable within the body of the airframe includes a housing defining an elongated cavity in which is mounted a wing supporting strut assembly having an elongated leading edge strut pivoted at one end within the stowable cavity and including a trailing strut that is foldable and pivotally connected at one end to the cavity structure and at the other end to the outer end of the leading edge strut and including a single layer of fabric stretched between the strut and clamped between the strut structure made up of separable, mirror image, strut links.

Abstract: An airborne missile launcher for air launching of man-portable, tube-launched missiles includes a central support frame with attachment means for detachable attachment to an aircraft or other launching platform, with a central frame member having a launch tube saddle support assembly at each side of the frame member with quick detachable clamp means and an alignment guide for quickly positioning and securing launch tubes into position with auto connecting means for automatically connecting the electronics control system and coolant gas to the launch tube assembly upon clamping the assembly into position. An aerodynamic shell encloses the support structure and includes a quick release cover for providing access to the tube clamp assemblies for loading and unloading launch tubes.
