    Abstract: An orbit-transfer vehicle provides the navigation, propulsion, and control systems required to transport a payload satellite from a geosynchronous-transfer orbit (GTO) to a predetermined low-earth orbit (LEO). Upon entering low-earth orbit, the payload satellite is deployed from the orbit-transfer vehicle. To reduce the cost and complexity of the payload satellite, the orbit-transfer vehicle is configured to provide common functional services, such as communications and power regulation, to the payload satellite during the transport, and/or after deployment. To reduce the fuel requirements for this deployment via the orbit-transfer vehicle, a preferred embodiment includes aerobraking to bring the satellite into a low-earth orbit. In a preferred embodiment of this method of deployment, the provider of the orbit-transfer vehicle identifies and secures available excess capacity on launch vehicles, and allocates the excess capacity to the satellites requiring deployment, thereby providing a deployment means that is virtually transparent to the purchaser of this deployment service.

    Abstract: An elongated rod made of a shape memory alloy composition having selected eudoelastic properties, is deformed into a dimensionally compact coil for packaged storage under stress maintained by physical constraint. Upon selective removal of the constraint allowing shape recovery, a substantial increase in axial length of the rod occurs in order to improve its performance in various installations, including long rod penetrating projectiles.

    Abstract: A method of producing a metal/ceramic composite structure in which an uncolidated metal or metal alloy powder is loaded into a sealable glass mold comprising a hollow ceramic sleeve and a sealable outer glass envelope surrounding the ceramic sleeve and forming with the outer wall of the ceramic sleeve a sealable chamber for the metal or metal alloy powder, wherein the glass is a type which becomes plastic when heated. The air in the mold is removed under vacuum and the mold is sealed and placed into a free flowing refractory powder in a crucible and consolidated by sintering under atmospheric pressure (CAP.RTM. process). Removal of the glass envelope leaves a composite article having a consolidated metal or metal alloy layer surrounding and placing a hollow ceramic liner (sleeve) under both radial and axial compression. A ceramic-line metal gun barrel insert can be produced by using a ceramic sleeve with rifling on its inner surface.

    Abstract: A method of producing a glass-lined metal pipe in which an unconsolidated tal or metal alloy powder is loaded into a sealable glass mold comprising a graphite core, a glass sleeve slipped over the graphite core with a sliding fit, a sealable outer glass envelope surrounding the graphite core and glass sleeve forming with them a sealable chamber for the metal or metal alloy powder, wherein the glass is a type which becomes plastic when heated. The air in the mold is removed under vacuum and the mold is sealed and placed into a free flowing refractory powder in a crucible and consolidated by sintering under atmospheric pressure (CAP.RTM. process). Removal of the glass envelope and the graphite core produces a glass-lined pipe in which the glass liner is slightly fused into and is under compressive force from the surrounding metal pipe.
