Patent number: 7750056Abstract: The inventions provide nanocrystallites and processes for the production of these nanocrystallites according to known silica-based sol-gel preparation principles based on hydrolysis/condensation mechanisms. The processes include a synthesis step comprising providing a homogenized colloidal dispersion of precursors, catalyst, and surfactant to form the sol matrix. The processes further include a novel drying step for a wet hydrogel intermediate product, including a short-cycle drying period during which the liquids present in this hydrogel can be evaporated at ambient pressure and low temperature ranges in any convenient drying apparatus while, inter alia, preserving the gel structure, especially gel porosity. Porosity values for the dried product up to about 98-99% can be attained, with product He densities as low as about 0.033 g/cc. Nanocrystallites produced by this process have, inter alia, excellent clarity, thermal insulation, acoustic insulation, surface scattering, and bulk modulus properties.Type: GrantFiled: October 2, 2007Date of Patent: July 6, 2010Inventor: Sami Daoud

Patent number: 6918340Abstract: This invention relates to a gas generator having two or more compartments, each with a separate initiator, with one compartment discharging before another, i.e., the compartments discharge sequentially. Each compartment has the same propellants, but the propellants have different geometries in each compartment, which results in different rates of gas evolution from each compartment. The gas generator has a rapid initial inflation, followed by a more gradual inflation rate in the subsequent stages, improving safety to occupants. One propellant used for the gas generator comprises (1) ammonium nitrate as the oxidizer, (2) a fuel such as CL-20. and (3) a binder such as polycaprolactone. A second propellant comprises by weight approximately 70-95% energetic nitrate fuel, 5-25% energetic polymer binder and 0.1-5% flash suppressant. No hot metal particles (e.g., CuO) are generated in the new systems.Type: GrantFiled: September 12, 2002Date of Patent: July 19, 2005Assignee: Textron Systems CorporationInventor: Sami Daoud

Patent number: 6877435Abstract: This invention relates to a gas generator having two or more compartments, each with a separate initiator, with one compartment discharging before another, i.e., the compartments discharge sequentially. Each compartment has the same propellants, but the propellants have different geometries in each compartment, which results in different rates of gas evolution from each compartment. The new gas generator is designed to reach maximum inflation at the same time as the current, single stage gas generators. However, the new generator has a more rapid initial inflation, followed by a more gradual inflation rate in the subsequent stages, improving safety to occupants. The propellant used in new generator comprises (1) ammonium nitrate as the oxidizer, which is less toxic and corrosive than the currently-used azide, (2) a fuel such as CL-20, and (3) a binder such as polycaprolactone. No hot metal particles (e.g., CuO) are generated in the new system.Type: GrantFiled: September 12, 2002Date of Patent: April 12, 2005Assignee: Textron Systems CorporationInventor: Sami Daoud

Patent number: 6818344Abstract: A thermal battery is housed in a chamber that utilizes micro-electromechanical systems (MEMS)-based technology to offer superior chemical stability and advantageous mechanical and thermal properties. The thermal battery of the present invention is activated by heat, for example heat generated by a pyrotechnic charge, for example thermite, for immediate and thorough activation of the electrolyte. The anode, cathode and electrolyte of the battery are formed of pellets having a curved interface for increased current density. The electrolyte preferably comprises a three-component eutectic salt mixture. In this manner, the thermal battery of the present invention is well suited for applications that require highly integrated thermal batteries that are relatively small in physical size, yet are capable of reliable performance over a wide range of operating conditions.Type: GrantFiled: April 12, 2002Date of Patent: November 16, 2004Assignee: Textron SystemsInventor: Sami Daoud

Patent number: 6761116Abstract: A high-precision pyrotechnic initiator is well adapted for rapid, precise ignition of solid and liquid energetics. A rigid housing, for example formed of an SiC-treated semiconductor substrate material, contains a pyrotechnic. When ignited, the reaction, or explosion, of the pyrotechnic is confined to the housing. The release of energy creates a hot particulate in which the formation of solid byproducts is mitigated or eliminated. The flame is directed through an outlet. In one embodiment, a microcapillary tube may be placed in communication with the outlet, the tube including a primary front vent and secondary side vents, which serve to increase system efficiency and reliability. A dual bridge wire may be provided for improving system reliability. The resulting assembly thereby performs the combined functions of both an igniter and a flash tube and a complete ignition train is provided in a manner that overcomes the limitations of the conventional configurations.Type: GrantFiled: April 12, 2002Date of Patent: July 13, 2004Assignee: Textron Sytems CorporationInventor: Sami Daoud
