Abstract: A method of launching and retrieving a UAV (Unmanned Aerial Vehicle) (10). The preferred method of launch involves carrying the UAV (10) up to altitude using a parasail (8) similar to that used to carry tourists aloft. The UAV is dropped and picks up enough airspeed in the dive to perform a pull-up into level controlled flight. The preferred method of recovery is for the UAV to fly into and latch onto the parasail tow line (4) or cables hanging off the tow line and then be winched back down to the boat (2).

Abstract: The present invention provides a composite matrix material which has (a) polyurethane; (b) inorganic particles which have outer surfaces and an aspect ratio of from at least about 1.5 to about 30; and (c) a silane coupling agent; wherein at least a portion of outer surfaces of the inorganic particles are in contact with the silane coupling agent. Also provided is a composite in which a composite matrix material is a polymeric matrix core which has a surface, and a thermoset layer is bonded to at least a portion of the surface of the polymeric matrix core. The composite is a high strength, durable part that may be used, for example, in manufacturing pallets and building or construction materials such as deck boards and siding and roofing panels, etc.

Abstract: A high strength, light weight composite has: (a) a core comprising a thermoset polymer and having a surface and (b) a laminate bonded to at least a portion of the surface of the core, the laminate comprising: (i) at least one layer of fibrous material having a surface, and (ii) at least one layer of thermoset binder which is bonded to at least a portion of the surface of at least one layer of fibrous material, each thermoset binder layer optionally comprising a low density filler. Also provided are methods for making and systems and apparatus for manufacturing the composite.

Abstract: This invention is directed to a wobble-torque hydraulic transmission device which has variable forward and reverse speeds and is also provided with a straight-through drive feature. The device is provided with a coaster brake feature that prevents the device from running away when going downhill. Also, the device is provided with a brake assembly that prevents rotation of the piston-pump means during forward and reverse operation but permits rotation for straight-through drive.
