Patent number: 10816450Abstract: A particle counter and classification system and method wherein a first stage magnetometer sensor subsystem for the fluid is tuned to detect and determine the size of ferrous and/or conducting particles in the fluid above a predetermined size. A pump is configured to drive a volume of the fluid through the first stage magnetometer sensor subsystem. A processing subsystem is responsive to the first stage magnetometer sensor subsystem and is configured to count the number of ferrous and/or conducting particles above the predetermined size based on the output of the first stage magnetometer sensor subsystem and to determine and report the concentration of the ferrous and/or conducting particles above the predetermined size as a function of the size of the particles, their number, and the volume of the fluid.Type: GrantFiled: December 14, 2018Date of Patent: October 27, 2020Assignee: Spectro Scientific, Inc.Inventors: Thomas G. Barraclough, Yuegang Zhao, Daniel Walsh

Patent number: 9791386Abstract: An integrated, portable sample analysis system and method. A viscometer subsystem receives a first portion of a sample. A spectrometer subsystem receives a second portion of the sample. A syringe pump subsystem receives a third portion of the sample and is configured to urge the third portion of the sample through a filter which collects particles in the sample thereon. An x-ray analysis subsystem is configured to x-ray the particles. The x-ray analysis subsystem also receives a fourth portion of the sample in order to determine the composition of any dissolved material in the sample. A processing subsystem provides a report concerning the sample and its viscosity, physical properties, particulate count and size distribution, and the composition of particulate and dissolved elements in the sample.Type: GrantFiled: January 24, 2012Date of Patent: October 17, 2017Assignee: Spectro Scientific, Inc.Inventors: Patrick F.

Patent number: 9234829Abstract: A viscometer assembly includes a first plate with a rail configured to constrain fluid thereon between its edges by surface tension. A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.Type: GrantFiled: January 13, 2014Date of Patent: January 12, 2016Assignee: Spectro Scientific, Inc.Inventors: Patrick F.

Patent number: 9176041Abstract: A particle quantifier includes a filter with a predetermined number of pores of a first predetermined size, a pump, and a fluid path from the pump to the filter. A pressure sensor is responsive to fluid pressure in the fluid path, and a processing module is responsive to the pressure sensor. The pressure increase of a sample fluid in the fluid path is determined as it is pumped through the filter and particles in the fluid are trapped by the filter. This pressure increase is compared with calibration data and an estimate is made concerning the concentration of particles greater than a second predetermined size present in the sample.Type: GrantFiled: June 19, 2012Date of Patent: November 3, 2015Assignee: Spectro Scientific, Inc.Inventors: Thomas G. Barraclough, Stephen D. Lawrence
