Patent number: 7949478Abstract: An in-situ lifespan is predicted for a hydraulic or pneumatic hose assembly for a particular installation, so that the hose assembly may be replaced before failure. A user of the apparatus, e.g. whilst on-site, is prompted to enter basic hose data together with a rating for a number of lifespan factors. The apparatus then determines a basic hose assembly lifespan based on the input hose data, and modifies the basic lifespan based on the ratings for the various lifespan factors. A hose assembly grading system is also described.Type: GrantFiled: March 18, 2005Date of Patent: May 24, 2011Assignee: Australasian Steel Products Pty LtdInventor: Leigh W Morrison

Patent number: 7650254Abstract: A method for detection and quantitative evaluation of a balance error occurring in a component-bearing system. Static and dynamic forces acting upon the bearing are determined by sensors of a measuring bridge, which are disposed on a rolling bearing and which change the inherent electrical resistance according to the applied pressure, and are made available for analysis in a computer in the form of a periodic test signal that is common to both forces. In order to analyze the test signal, the weighted average of the modulation frequency generated by a balance error and the weighted mean variance thereof are determined from the test signal. The variance is then compared with a given variance threshold value. A variance lying below the variance threshold value is considered to be an indication of a significant balance error in the bearing.Type: GrantFiled: February 4, 2004Date of Patent: January 19, 2010Assignee: Schaeffler KGInventors: Alfred Pecher, Stefan Glück, Joachim Hering
