Appl. No.:

10/104530

Inventors:

Timothy Barry - Chicago IL, US
Guy Gunzberg - Evanston IL, US
Paul Manzano - Chicago IL, US

International Classification:

G09B003/00

US Classification:

434/350000, 434/169000

Abstract:

A user-controlled network based learning system allows the user to select an appropriate learning method for the user, as well as the material relevant to the user, to maximize the learning experience for the user. The system provides a mechanism for information sharing within, and out of, the learning system. Upon deciding to participate in a learning lesson, the user first determines whether to participate in an already developed learning lesson, or to create their own learning lesson based on the breakdown of previously developed learning lessons and criteria the user determines relevant to their desired learning objective. Upon selection of the lesson, the user then determines an appropriate learning method in which to conduct the learning lesson. Based on the selection of the learning method, the user will again determine the information relevant to their desired learning objective. Within the learning system, the user may share information across the population of users in the learning system, as well as other defined individuals outside of the learning system. Upon completion of individual learning lessons, the learning system provides tools to monitor, for any period of time, user implementation of key lessons learned into daily requirements.

Abstract:

The magnetic-drive assembly has an axial bearing which is strategically located to minimize compressive forces on a primary shaft. The axial bearing functions both as an ordinary thrust bearing and an inefficient impeller for circulating fluid internally within the magnetic-drive assembly. The axial bearing circulates lubricating fluid to a radial bearing to promote bearing longevity. The magnetic-drive assembly has a shaft adjustment mechanism for adjusting the axial orientation of a primary shaft and impellers with respect to a housing. The shaft adjustment mechanism retains its fixed axial orientation despite exposure to vibration and shock produced by the pump.
