Magnetic And Ultrasonic Discriminator For Particle Size Distribution Analyzer

US Patent:

59182725, Jun 29, 1999
Filed:

Apr 12, 1996
Appl. No.:

8/631492
Inventors:

Dane Thomas Snyder - Byron CA
Robert James Law - Livermore CA
Michel Noel Robles - Livermore CA
Roger William Caputi - Walnut Creek CA
Assignee:

General Electric Company - San Jose CA
International Classification:

B01D 3506
B03C 102
B03C 130
C02F 148
US Classification:

73 6142
Abstract:

A flow-through system for determining the particle size distribution of iron oxide particulate matter in a reactor water sample. The system includes a magnetic filter having a chamber through which a stream of reactor water. The chamber is surrounded by a winding which is coupled to an electrical circuit for generating a varying magnetic field which interacts with any magnetic particulates entrained in the water sample flowing through chamber. When a strong magnetic field is established, magnetic particles are filtered out of the water stream flowing through the chamber by magnetic attraction. Therefore, only particles which are non-magnetic or slightly magnetic pass through the magnetic filter. The particles which pass through the magnetic filter then enter a conventional particle distribution analyzer which counts and sizes the particles in the water stream flowing therethrough.

US Patent:

53772342, Dec 27, 1994
Filed:

Oct 23, 1992
Appl. No.:

7/965323
Inventors:

Michel N. Robles - Livermore CA
Dane T. Snyder - Byron CA
Assignee:

General Electric Company - San Jose CA
International Classification:

G21C 1700
US Classification:

US Patent:

44723547, Sep 18, 1984
Filed:

Jun 7, 1982
Appl. No.:

6/385814
Inventors:

Thomas O. Passell - Palo Alto CA
Michel N. Robles - Livermore CA
James L. Simpson - San Jose CA
Constantine N. Spalaris - San Jose CA
Assignee:

Electric Power Research Institute, Inc. - Palo Alto CA
International Classification:

G01N 3108
G01N 3104
US Classification:

422 62
Abstract:

An on-line and continuous sampling system for monitoring the ionic content of steam-producing water in a steam-operated electrical power plant. The monitoring system comprises a plurality of sampling lines and associated apparatus for sampling the steam-producing water at a number of different points in the power plant, an ion chromatographic subsystem for analyzing the sampled water, a calibration subsystem for calibrating the ion chromatographic subsystem, and an automatic control subsystem for operating the monitoring system of the present invention.

US Patent:

52081656, May 4, 1993
Filed:

Jan 31, 1991
Appl. No.:

7/648096
Inventors:

Robert J. Law - Livermore CA
Michel N. Robles - Livermore CA
Dane T. Snyder - San Jose CA
Assignee:

General Electric Company - San Jose CA
International Classification:

G01N 3318
US Classification:

436176
Abstract:

Water testing means for monitoring circulating water coolant in service within a water cooled nuclear reactor system is disclosed. The invention is an improvement in such water testing means and comprises a preconditioning of selected sample specimens of water with a pH adjustment for inhibiting unbalancing an equilibrium in solution of water coolant with ion solutes.
