Unidirectional composite stiffening
Simple structural elements are explored with configurations selected to best utilize composite materials. Combination of the biaxial properties of beryllium or an isotropic composite with the uniaxial properties of one directional filamentary reinforcement is studied.
Detonation hazards with ''safe'' industrial solvents
Sensitivities of various metal/halocarbon slurries to impact are given. Barium and lithium shavings show sensitivity with all of the halocarbons tested except methyl chloroform. Powdered aluminum, magnesium titanium, and beryllium show sensitivity with several halocarbons but generally require a higher level of initial energy.
Flexible electrical conductors for high-temperature switchgear
Arch-shaped conductors fabricated from flat strips of beryllium oxide dispersion-strengthened copper alloy serve as flexible electrical connectors capable of operating in 1000 deg F temperature range, under vacuum conditions for periods of 10,000 hours or more without failure.
Flexible pivot mount eliminates friction and hysteresis
Flexible steel pivot mount, suspended by flat vertical beryllium copper springs, is capable of rotation, free of hysteresis and starting friction. Mount requires no lubrication, is made in varying sizes, and is driven with either dc torque motor or mechanical linkage.
