Application of hydraulically assembled shaft coupling hubs to large agitators

Description: This paper describes the basis for and implementation of hydraulically assembled shaft coupling hubs for large tank-mounted agitators. This modification to the original design was intended to minimize maintenance personnel exposure to ionizing radiation and also provide for disassembly capability without damage to shafts or hubs. In addition to realizing these objectives, test confirmed that the modified couplings reduced agitator shaft end runouts approximately 65%, thereby reducing bearing lo… more

Evaluation of mixing systems for biogasification of municipal solid waste

Description: Two specially selected mixing systems were tested and evaluated to determine how effectively they could prevent the formation of fibrous mats and stringers during the anaerobic digestion of a slurried mixture of preprocessed municipal solid waste and sewage sludge to produce methane gas. The tests were conducted in a modified 10.7-m (35-ft) diameter, nominal 378,000-liter (100,000-gal) capacity concrete vessel in the Franklin, Ohio, environmental complex. Between August 1977 and September 1978,… more

NMR parallel Q-meter with double-balanced-mixer detection for polarized target experiments

Description: A constant-voltage, parallel-tuned nuclear magnetic resonance (NMR) circuit, patterned after a Liverpool design, has been developed for polarized target experiments. Measuring the admittance of the resonance circuit allows advantageous use of double-balanced mixer detection. The resonant circuit is tolerant of stray capacitance between the NMR coil and the target cavity, thus easing target-cell-design constraints. The reference leg of the circuit includes a voltage-controlled attenuator and pha… more
