| 20100163340 | ULTRA LIGHTWEIGHT SEGMENTED LADDER/BRIDGE SYSTEM - A dual-use ladder and bridge modular system preferably includes tubes, gussets, flanges, and/or joints. In a preferred embodiment, the tubes, gussets, flanges, and/or joints are made of carbon fiber. A method connects and disconnects modular carbon fiber ladder segments. Another method creates a lightweight carbon-fiber beam with exceptionally high stiffness and strength using a combination of carbon-fiber braid material, uni-directional cloth, and pultruded carbon-fiber strips. A carbon fiber ladder segment and tube connectors are also disclosed. | 07-01-2010 |
| 20100175556 | MULTI-USE PERSONAL VENTILATION/FILTRATION SYSTEM - A ventilation device uses a cross-flow fan and one or more filters, where the filter preferably has a J-shape that at least partially surrounds the rotor of the cross-flow fan. In one embodiment, the filter includes a plurality of pleats, preferably along a bottom surface of the filter. The filters preferably remove particles, undesired gases, and micro-organisms. A filtration and ventilation system with at least one first ventilation device and at least one second ventilation device larger than the first ventilation device, as well as a method of filtering contaminants out of air using a personal ventilation device, are also disclosed. | 07-15-2010 |
| 20100192506 | 3-DIMENSIONAL UNIVERSAL TUBE CONNECTOR SYSTEM - The present invention includes a system for connecting tubes or rods, which are preferably uni-directional pultruded, filament wound, or roll-wrapped carbon-fiber tubes or rods, together to form trusses and other structures using a series of connector pieces preferably bonded together with adhesive. | 08-05-2010 |
| 20100212476 | Tool For Setting An Instrument Sound Post - A tool for setting an instrument sound post preferably includes a bent tube, one or more string or polymer lines, a cradle end that grasps the sound post, and an internal locking mechanism to hold the sound post against the tool. In one embodiment, a single line is used and a closed loop at the cradle end of the sound post setting tool holds the sound post in place. In this embodiment, a double-chamfer threaded tube construction is preferably used to facilitate line threading. In another embodiment, the cradle end includes a loop and a ball to grasp the sound post. In yet another embodiment, the cradle end includes two balls to grasp the sound post. The tool provides an improved way to install a sound post inside a stringed instrument. | 08-26-2010 |
| 20110194889 | 3-Dimensional Universal Tube Connector System - The present invention includes a system for connecting tubes or rods, which are preferably uni-directional pultruded, filament wound, or roll-wrapped carbon-fiber tubes or rods, together to form trusses and other structures using a series of connector pieces preferably bonded together with adhesive. | 08-11-2011 |
| 20110209947 | ULTRA LIGHTWEIGHT SEGMENTED LADDER/BRIDGE SYSTEM - A dual-use ladder and bridge modular system preferably includes tubes, gussets, flanges, and/or joints. In a preferred embodiment, the tubes, gussets, flanges, and/or joints are made of carbon fiber. A method connects and disconnects modular carbon fiber ladder segments. Another method creates a lightweight carbon-fiber beam with exceptionally high stiffness and strength using a combination of carbon-fiber braid material, uni-directional cloth, and pultruded carbon-fiber strips. A carbon fiber ladder segment and tube connectors are also disclosed. | 09-01-2011 |
| 20110267749 | ROBUST LIGHTWEIGHT ELECTRONIC RACK ENCLOSURE - The embodiments of the instant invention comprise a lightweight, robust electronic rack enclosure. The embodiments are comprised of an outer chassis, an inner chassis, bottom vibration isolators, and top vibration isolators. The outer chassis is comprised of an outer chassis door, two outer chassis side assemblies, an outer chassis top panel, an outer chassis bottom panel, and an outer chassis back panel. The inner chassis is comprised of two inner chassis side assemblies, an inner chassis top panel, and an inner chassis bottom panel. Each outer chassis side assembly is comprised of a flat outer chassis side panel, one or more diagonal reinforcing members, one or more horizontal reinforcing members, and one or more vertical reinforcing members. The inner chassis side assemblies are comprised of an inner chassis flat side panel, and one or more inner chassis side panel horizontal supports. | 11-03-2011 |
| 20120025437 | LIGHTWEIGHT CARBON FIBER C-CLAMP - The carbon fiber c-shaped clamp tool is preferably used in wood working and instrument manufacturing. The carbon fiber c-clamp tool preferably includes a main body, carbon fiber sleeves, pads, one or more threaded rods, and turning knobs. In a preferred embodiment, the main body and sleeves are made of unidirectional carbon fiber. A method connects the main body and sleeves by extending the carbon fibers from the main body to the sleeves and wrapping them around threaded inserts. | 02-02-2012 |
