20130292909 | Seals - An elastomeric or polymeric seal assembly ( | 11-07-2013 |
20130275056 | COMPONENT FAILURE DETECTION SYSTEM - An apparatus for detecting fatigue induced failure of an assembly having a single flexible element or a series of flexible elements stacked in juxtaposed engagement, for transmitting power from one component to another, the assembly having a cyclic operating speed frequency includes at least one sensor mounted in proximity to said assembly, the sensor providing an analogue signal corresponding to an airborne acoustic signal emitted by the assembly, means for amplifying the analogue signal, filter means to reduce background noise from the analogue signal, an analogue to digital converter for converting the analogue signals to a digital signal, means for sampling the digital signals in respect of the operating speed frequency of the assembly and means for analysing the digital signals and providing an output upon the occurrence of one or more digital signal spikes in an operating cycle. | 10-17-2013 |
20120098204 | Seal Assemblies - A seal assembly for providing a seal between a pair of relatively rotatable components has; a first seal ring ( | 04-26-2012 |
20110140366 | IMPROVEMENTS IN AND RELATING TO SPRING ENERGISED PLASTIC SEALS - A seal assembly for providing a seal between a pair of components has a sealing ring made of flexible plastics material and a backup ring ( | 06-16-2011 |
20110084454 | INTERNALLY PRESSURIZED SEALS - A seal assembly having a first seal ring sealed to a rotatable component and a second seal ring sealed to another rotatable component, and the second ring is urged towards the first ring such that sealing faces of the seal rings engage. A process chamber is formed inside the seal rings and opens to an outside the seal rings, and a barrier chamber outside of the seal rings opens to inside the seal rings. A shroud shields the external surface of the seal rings from process fluid in the process chamber such that heat transfer from the process fluid to the seal rings occurs at outer regions of the seal rings adjacent the sealing faces, and a sleeve is secured inside the seal rings such that heat transfer between the seal rings and barrier fluid in the barrier chamber occurs at radially extending surfaces of the seal rings adjacent the sealing faces. | 04-14-2011 |
