Progressive Cavity Pump With Meltable Stator
Progressive Cavity Pump With Meltable Stator
US Patent:
6220838, Apr 24, 2001
Filed:
Nov 3, 1999
Appl. No.:
9/432208
Inventors:
Alfred M. Osborne - Bluffdale UT
Assignee:
Dyno Nobel Inc. - Salt Lake City UT
International Classification:
F04C 2107, F04C 500, F04C 1300
US Classification:
418 1
Abstract:
The invention comprises a progressive cavity pump for pumping a flowable explosive composition or other heat-sensitive material comprising an inlet and an outlet; a stator that is meltable at or above a selected maximum pump operation temperature; a rotor, and a drive shaft connecting the rotor to a power source; wherein the stator will melt above the selected temperature to prevent the generation of temperatures within the pump high enough to create a hazard. The invention also relates to a method of safely pumping a flowable explosive composition or other heat-sensitive material comprising the use of a progressive cavity pump having a stator that is meltable above a selected maximum pump operation temperature for the similar result.

Patrick J. Harder - Kingston NY
International Classification:
C06C 504
US Classification:
1022758
Abstract:
The invention relates to a method of manufacturing a low-energy shock tube by co-extruding two or more layers simultaneously wherein the inner layer has an adhesive affinity for a powdered reactive material and the outer layer(s) provides abrasion, cut and other environmental resistance to the tube. The wall thickness of the inner layer is less than about 0. 3 millimeters. The invention also relates to a low-energy shock tube having such configuration and inner layer thickness.
