116212000 | Stress type | 6 |
20080251002 | Tension Indicator - A tension indicator comprises a housing ( | 10-16-2008 |
20080264327 | Strain-Responsive Visual Indicator - A strain-responsive visual indicator comprises a pair of overlapping shutter strips ( | 10-30-2008 |
20090301383 | INDICATING FASTENER LOADING - An amplified indication of the elongation of a fastener is provided for determining instantaneous loading conditions of a fastener. A load indicator is couplable to a fastener for instantaneous load measurement and includes a housing defining a fastener interface configured to removably couple the housing to a fastener. A moveable datum probe extends from the housing in contact with a datum rod anchored within an internal bore of the fastener. A first lever is pivotally mounted within the housing and is moveable in response to displacement of the datum probe. A load display indicates a degree of loading of a fastener as a function of displacement of the datum probe. A second lever can be used to further amplify the reading from the displacement of the datum probe. An inclined visual scale and a multi-faceted lens allows for viewing of loading values from multiple directions or angles. | 12-10-2009 |
20140102354 | PRESSURE INDICATOR - A pressure indicator for a high-pressure accumulator system, and which includes a pressure indicating element having a channel. The pressure indicating element moves between a starting position and a pressure-indicating position in response to pressure on a side facing a pressure-monitoring region and which is counter to a force of at least one compression spring on the pressure indicating element. | 04-17-2014 |
20140209010 | PERFORMANCE AND/OR STRESS-INDICATING DEVICE - Performance indicating device ( | 07-31-2014 |
20150338296 | STRUCTURAL REPAIR HAVING OPTICAL WITNESS AND METHOD OF MONITORING REPAIR PERFORMANCE - A structural repair includes a tell-tale optical witness that allows the health of the repair to be visually monitored. The optical witness includes a stress sensitive fluorescent dye that shows changes in local strain/stress patterns when the repair is subjected to electromagnetic energy of a particular wavelength. The dyes fluoresce more or less strongly as a function of the local stress/strain. | 11-26-2015 |
