20080229683 | Buckling restrained brace for structural reinforcement and seismic energy dissipation and method of producing same - A buckling restrained brace includes a deformable core contained within an outer casing. Ends of the core protrude from the casing for connection to a frame or other structure. A length of the deformable core between its ends, referred to as the gauge or yielding section, is capable of deforming during an earthquake or blast loading. The gauge section is differentially heat treated from the ends so that the gauge section has a lower yield strength than the ends. The casing provides containment of the core to prevent buckling of the core. A metal foil interface or unbonding layer is provided between the deformable core and the casing so that the deformable core does not bind to the casing. The buckling restrained brace provides significant performance improvements over prior art BRBs coupled with simplified assembly. | 09-25-2008 |
20090045286 | Grid fin control system for a fluid-borne object - A grid fin control system for a fluid-borne body includes a nozzle extension, an optional stabilization device, and a plurality of grid fins. The grid fins are stowable folded against the nozzle extension and deployable to extend radially outwardly. | 02-19-2009 |
20090126288 | Shape memory alloy composite material shock and vibration isolator devices - A shock and vibration isolator device has one or more connecting elements of a superelastic shape memory alloy composite material extending between a base member, configured to mount to a structure or ground, and a mounting member, configured to support equipment or machinery. The superelastic shape memory alloy composite material is formed of a plurality of superelastic wires embedded in an elastomeric matrix material. | 05-21-2009 |
20090126860 | Prepeg pultrusion - Continuous pultrusion of prepreg material systems is provided. A prepreg material, comprising fibers infiltrated with a partially cured resin, is introduced into a pultrusion die with a barrier layer between surfaces of the prepreg material and facing inner surfaces of the die. The prepreg material and the barrier layers are continuously pulled through the pultrusion die. The barrier layer is removed from each surface of the prepreg material after exiting the die. | 05-21-2009 |
20100012774 | Powered unmanned aerial vehicle - An unmanned aerial vehicle mounts a payload section to an air delivery vehicle. The air delivery vehicle includes deployable wings and tail fins for gliding or powered flight. A set of propeller blades are provided for powered flight. The propeller blades are mounted for movement from a stowed position to deployed position extending radially from the fuselage for powered flight. | 01-21-2010 |
20100065560 | MODULAR PACKAGING SYSTEM - A modular packaging system of containers each having a generally tubular, hollow container body of a fiber-reinforced composite material with cooperative mating interlocking elements extending axially along its length. The interlocking elements allow the containers to be stacked and palletized in a stable manner. An interface between a closure mechanism and the container body provides a good seal and prevents fraying or brooming of the fiber-reinforced composite material at the end face of the body. | 03-18-2010 |
20100123108 | DEVICE FOR TRANSFERRING A LOAD FROM AN OBJECT TO A LOAD-BEARING ELEMENT - A device for transmitting a load from an object to a load-bearing element is provided. The device includes an attachment mechanism for attaching to a load-bearing element, such as a vertical stanchion. A loading mechanism includes a pressure block and a mechanism interconnecting the pressure block and the attachment mechanism. The loading mechanism can apply a preload to an object and transmit a force from the object to the load-bearing element. | 05-20-2010 |
20100155033 | THERMAL MANAGEMENT SYSTEM USING MICRO HEAT PIPE FOR THERMAL MANAGEMENT OF ELECTRONIC COMPONENTS - A thermal management system includes a base element and a heat producing element disposed for heat transfer from the heat producing element to the base element. An adherent zone includes an adherent element in physical attachment between the heat producing element and the base element. A heat transfer zone, separate from the adherent zone, includes a heat pipe between the heat producing element and the base element. The heat pipe includes a circulatory flow path between an evaporator section and a condenser section, and a working fluid on the circulatory flow path. | 06-24-2010 |
20110041425 | BUCKLING RESTRAINED BRACE FOR STRUCTURAL REINFORCEMENT AND SEISMIC ENERGY DISSIPATION - A buckling restrained brace includes a deformable core contained within an outer casing. Ends of the core protrude from the casing for connection to a frame or other structure. A length of the deformable core between its ends, referred to as the gauge or yielding section, is capable of deforming during an earthquake or blast loading. The gauge section is differentially heat treated from the ends so that the gauge section has a lower yield strength than the ends. The casing provides containment of the core to prevent buckling of the core. A metal foil interface or unbonding layer is provided between the deformable core and the casing so that the deformable core does not bind to the casing. The buckling restrained brace provides significant performance improvements over prior art BRBs coupled with simplified assembly. | 02-24-2011 |
