Abstract: An improved hydration system for runners that provides superior motion control and easy dispensing. Fluid is contained within a flexible bladder and pack, and attached to the waist. The pack is constructed of comfortable, elastic, and thermally-insulating fabric. When attached to the waist, tension in the fabric compresses the bladder against the user and dampens motion. Uniform distribution of fluid in the bladder contributes to motion control and is provided by a flexible plastic compression plate and snap elements that pinch the lower portion of the bladder. The snap elements can be disengaged to allow the bladder to be fully expanded for easy cleaning and drying. Fluid is dispensed from a small waist-mounted squeeze bottle that fills automatically from the bladder via fluid coupling elements. Check valves ensure that fluid flows unidirectionally from bladder to bottle to user, and prevent air infiltration into the squeeze bottle and bladder.

Abstract: A method of removing and reinstalling multiple floor-beams concurrently while minimizing aircraft movement. The airplane is supported with jacks in a manner that minimizes internal shear and bending moment stresses. All floor-beams needing to be replaced are removed concurrently. All floor-attach structure such as floor panels, intercostals, seat-tracks, hard points, cargo handling equipment, and electrical and hydraulic standoffs is also removed. Deformation of the airplane is monitored and any significant deformation is restored. A floor-beam complex consisting of floor-beams, and all floor-attach structure such as floor panels, intercostals, seat tracks, hard points, cargo-handling equipment, and electrical and hydraulic standoffs is installed in place of the removed floor structure. The floor-beam complex has splices to facilitate handling during installation. More than one floor-beam complex may be required for a complete airplane.

Abstract: An expandable honeycomb product which is formed by printing an adhesive pattern onto a plurality of webs of a suitable core material. The unit of adhesive pattern is a truncated triangle which is repeated at intervals along webs of core material, which are stacked such that the adhesive pattern is staggered relative to each web. When expanded, the webs deform into a honeycomb product composed of a repeating pattern of six-sided cells. Each cell may have a different inner and outer height and width, due to the introduction of differential inner and outer waveform wavelength and amplitude by adhesive pattern, allowing the production of non-planar honeycomb product which may be deformed into a structure having small radius curvatures about either axis or both axes along the surface of the honeycomb structure.
