International Classification:

G01N 11/00
H05K 13/00

US Classification:

73 5442, 295921

Abstract:

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.

International Classification:

G06F 19/00

US Classification:

702 50

Abstract:

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.

Assignee:

United Technologies Corporation - Hartford CT

International Classification:

F16J 1516

US Classification:

277 961

Abstract:

A seal assembly 46 for a rotary machine 10 is disclosed. Various construction details are developed which block the migration of oil from a compartment such as a bearing compartment 22. In one detailed embodiment, an annular clearance gap G is provided with an outwardly tapered surface (98; 118; 98, 118) to energize a boundary layer or to block lubricating fluid from migrating from the bearing compartment.

Inventors:

Eric Paul Olson - Newburyport MA, US

International Classification:

G09B 23/04
G09B 1/00

Abstract:

A slope measurement and drawing aid () for teaching mathematics having unique indicia (), rational-numeric slope values (), and mathematical information (), and a method of identifying the correct rational-numeric slope value associated with the graph of a given line, either by means of a gravity-activated indicator arm (), or by means of the orientation of the teaching aid. For instructional purposes, when used in a classroom setting, the teaching aid can be removably held on a vertical board by magnetic (R) or other means. When used in an individual setting, a smaller version of the teaching aid can similarly be used in a horizontal orientation on paper.

International Classification:

G01N 23/06

Abstract:

An integrated portable sample analysis system includes a portable case including an interior panel and a spectrometer subsystem. The spectrometer subsystem includes a flip top spectrometer sample cell including first and second members each including a window aligned with each other when the first and second members are coupled together defining a predefined spacing between the windows when the first and second members are coupled together, the first and second members decoupled for manually placing a fluid sample on a the window. An analyzer behind the interior panel receives the flip top spectrometer sample cell therein when the first and second members are coupled together for analyzing the fluid sample located between the windows by directing radiation through the windows and the fluid sample. The flip top spectrometer sample cell is configured to be withdrawn out of the analyzer for cleaning of the windows. The integrated portable sample analysis system also includes a viscometer subsystem including a flip top sample viscometer cell. The flip top sample viscometer cell includes a first plate including a rail configured to constrain a fluid sample manually presented thereto between its edges by surface tension, and a second plate including a surface spaced from the rail by a predefined gap for constraining fluid to the rail by surface tension when the rail is inclined by gravity and pulls the fluid along the rail. An analysis unit is behind the interior panel receiving the flip top viscometer sample cell therein when the first and second plates are coupled together for defining the viscosity of the sample flowing along said rail, and the flip top viscometer sample cell is configured to be withdrawn out of the analysis unit for cleaning of the rail. A processing subsystem is associated with the portable case and responsive to the spectrometer subsystem and the viscometer subsystem and configured to process outputs of the spectrometer subsystem and the viscometer subsystem and to provide a report concerning the sample, its physical properties, and its viscosity.
