Patent number: 5181678Abstract: A flexible airfoil section for a wing or a blade comprising a streamlined shape and an elastic structure whose stiffness distribution along its chord and span is tailored to provide a desirable cambered shape with proportional increases in camber with increases in lift, mounted to a supporting structure such that the airfoil sections are free to pivot about axes near their leading and trailing edges. In operation, the foil derives much of its lift from elastic bending deformation of its flexible shape, thereby achieving a higher lift than a symmetric foil at the same angle of attack while postponing the onset of flow separation and stall and, for operation in water, of ventilation and cavitation.Type: GrantFiled: February 4, 1991Date of Patent: January 26, 1993Assignee: Flex Foil Technology, Inc.Inventors: Sheila E.

Patent number: 5177618Abstract: A dual deck video cassette recorder, having first and second video decks in a common housing. Each deck has a plurality of heads and both of the decks can playback, and at least one of the decks can record. A switch arrangement is connected to both decks to provide for selective connections of video and audio signals between, and from the inputs to and outputs from, the two decks. A sensor detects the angular position of the heads of each deck to assure they are in phase prior to initiating recording. A mechanism corrects the angular position of the heads of at least one of the decks to assure the heads of each will be in the same angular phase prior to initiating recording. A circuit detects a copy protection signal on a tape in one deck during vertical blanking and the signal is located and timed so that it will not interfere with normal operation of the video signals, to produce a quality picture on a TV monitor or place information onto tape in one deck which provides a quality picture.Type: GrantFiled: June 29, 1990Date of Patent: January 5, 1993Assignee: Go-Video, Inc.Inventors: R.
