Abstract: An aircraft having a wing with a top surface and a bottom surface, with the top surface having a first plurality of jets containing flow straighteners integrally hinged to the skin of the aircraft and positioned to direct air rearwardly along the top surface of the wing and the bottom surface having a second plurality of jets containing flow straighteners integrally hinged to the skin of the aircraft and positioned for directing air forwardly along the bottom surface of the wing and a compressor for receiving outside air and pressurizing the air which is then directed rearwardly along the top of the wing to decrease the pressure on top of the wing and forwardly along the bottom surface of the wing to increase the pressure on the bottom of the wing to increase the lift of the wing and thereby increase the lift and permit the aircraft to takeoff and land at a ground speed slower than if the pressurized air was not directed over the wing.

Abstract: A one-piece polymer plastic shut-off valve that includes a conduit with a first end having a sealing surface thereon and an engagement surface for connection to a fluid system and a plug with a further sealing surface that is yieldably supported in a spaced condition from the sealing surface of the conduit by elongatable supports to allow fluid to flow through said conduit under a first flow condition when the elongated supports are not extended and to prevent flow of fluid through said conduit under a second flow condition when the elongated supports are extended.
