A hollow spherical segment valve with an eccentric permits non-rubbing closure and provides a means for gas-cooling the seal. The design allows quick opening at high temperatures and discharge pressures.
In vitro d-glucose absorption by intestinal segments from active and hibernating, irradiated and nonirradiated ground squirrels
Absorption of d-glucose by intestinal segments
Explosive forming technique to produce torus tank sump segments of aluminum alloy 7039
Circumferentially segmented-ring electrode replaces the solid-ring electrode in a basic magnetohydrodynamic /MHD/ accelerator. This produces diffuse discharges at pressures as high as 100 atmospheres.
Heat transfer measurements on blunt spherical segment nose and cylindrical body and flight test of rocket-propelled model
Prestressed segmented brittle materials in aerospace structures
Equilibrium nonlinear differential and buckling equations for segments of toroidal shallow shells near equator and crown
Local, segmental and supraspinal interaction with dorsolateral spinal cutaneous afferent system, examining electric stimulation effects
Atom concentration calculated for linear segments of analytical curves in atomic flame spectrometry
Equilibrium nonlinear differential and buckling equations for segments of toroidal shallow shells near equator and crown
Segmented ball valve and flowmeter in the same spherical housing provide a valve that will handle large fluid volume without bulkiness and weight of blade valves or conventional ball valves. The valve is easily opened or closed and the flowmeter remains stationary, so errors are eliminated.
Large diameter seals are fabricated from narrow strip stock welded in segments to form a complete ring. This technique could be used to reduce the cost of critical, large diameter seals in the heating and ventilating industry, petrochemical industry, and marine fabrication industry.
Prolonged hot or cold stimulation effects on eye movements, vestibulospinal, and segmental spinal activities in monkeys
