High-rate centreless grinding of ferrous components.
… grinding machine was modified extensively to operate satisfactorily at high grinding wheel speeds and in the high rate centreless grinding regime. The principal modifications included the provision of a 75 k. W. d. c., variable speed, main drive motor which enables grinding wheel speeds up to 120 …

Kinetic and hydraulic studies in high-rate biological filters
Most published work on either low- or high-rate biological filters covers one of three topics: kinetics, microbiology/ecology or hydraulics. These areas have been re-examined together for high-rate filters in order to further integrate them and enable appropriate utilization of low-rate filter …

Design and analysis of a high-rate acoustic link for underwater video transmission
A high bit rate acoustic link for underwater video transmission is examined. Currently, encoding standards support video transmission at bit rates as low as 64 kbps. While this rate is still above the limit of commercially available acoustic modems, prototype acoustic modems based on phase coherent …
