  • Neurotrophic factor
    Patent number: 5665862
    Abstract: The invention pertains to isolated neurotrophic factors, designated as ARIA, which are able to induce the formation of ion channels in a surface membrane of a cell. The amino acid sequence of the neurotrophic factors includes an EGF-like domain, and a second amino acid sequence encoded by at least a portion of an exon of the neurotrophic factor gene normally expressed in a neuronal cell, especially a nerve cell. The neurotrophic factor is distinct from, and essentially unrelated to, the chicken prion-like protein previously identified.

  • Ancillary aerodynamic structures for an unmanned aerial vehicle having ducted, coaxial counter-rotating rotors
    Patent number: 5419513
    Abstract: An unmanned aerial vehicle (UAV) having a toroidal fuselage and a rotor assembly including counter-rotating rotors coaxially mounted with respect to the toroidal fuselage incorporates ancillary aerodynamic structures aerodynamically configured and mounted in combination with the toroidal fuselage to provide a nose-down pitching moment to counteract the nose-up pitching moment generated by airflow over the toroidal fuselage during forward translational flight of the UAV. The ancillary aerodynamic structures have a cambered airfoil profile to provide high lifting forces.

  • Infra-red suppressor for use with turbo-shaft engine
    Patent number: 4004416
    Abstract: An infra-red radiation suppressor adapted to be positioned to alter the flow of the exhaust gases of a turbo-shaft engine and sized to block view into the engine outlet and including self-pumping ejector means to cool the visible surfaces of the suppressor.BACKGROUND OF THE INVENTION1. Field of InventionThis invention relates to infra-red radiation suppression and more particularly to an infra-red radiation suppressor which is adapted to be mounted to block the view into the outlet of a turbo-shaft engine and to intercept and alter the flow of exhaust gases thereof and which includes self-pumping ejector mechanisms to provide cooling of the exposed suppressor parts.2.
