  • Publication number: 20120035885
    Abstract: Vibration amplitudes are recorded as a function of rotation speed and of frequency and the data is analyzed to estimate a noise floor amplitude threshold for each of a plurality of different speed and frequency sub-ranges. On the basis of training data known to be normal speed-frequency areas which contain significant spectral content in normal operation are deemed “known significant spectral content”, so that during monitoring of new data points which correspond to significant vibration energy at speeds and frequencies different from the known significant spectral content can be deemed “novel significant spectral content” and form the basis for an alert. The estimation of the noise floor is based on a probabilistic analysis of the data in each speed-frequency area and from this analysis an extreme value distribution expressing the probability that any given sample is noise is obtained.

  • Patent number: 7640802
    Abstract: A method of analysing tachometer and vibration response data from an apparatus having one or more rotary components is provided. The method comprises the steps of: providing vibration response data and corresponding tachometer data from the apparatus for a period over which a rotary component of the apparatus varies in rotational speed, the tachometer data being for that component; repeatedly performing at intervals throughout the period the sub-steps of: determining a forcing frequency of the component from the tachometer data and a corresponding vibration response frequency of the apparatus from the vibration response data, comparing the forcing and vibration response frequencies to determine the relative phase difference between the frequencies, and determining the corresponding amplitude of the vibration response from the vibration response data; and plotting the relative phase differences and vibration amplitudes on a polar diagram.

  • Publication number: 20060265153
    Abstract: Novel tracked orders (i.e., tracked orders that are not present in “healthy” machinery) are useful for locating bearing anomalies. Accordingly, a method for locating bearing anomalies in machinery is provided that includes receiving vibration measurements acquired from the machinery, analyzing the vibration measurements to identify novel tracked orders indicative of bearing anomalies, and ascertaining the location of a bearing anomaly by relating a novel tracked order thus-identified to one or more further tracked orders. Thus, the novel tracked order does not merely indicate the occurrence of a bearing anomaly, but, in combination with the one or more further tracked orders, allows the bearing anomaly to be traced to a particular position.

  • Patent number: 7127892
    Abstract: One embodiment of the present invention includes an internal combustion engine with a turbocharger. The turbocharger includes a compressor with an outlet coupled to an intake of the engine and a turbine coupled to an exhaust manifold of the engine. A a turbocharger speed estimate is determined from engine speed and a ratio between inlet and boost pressure for the compressor. The turbocharger speed estimate is further adjusted as a function of compressor boost pressure variation with time.

  • Publication number: 20050252874
    Abstract: The present invention increases the capacity and resistance to closure of the draft gear assembly by providing an angled bottom surface on the tapered plates intermediate of the inner and outer friction surface in the area where the taper plate contacts the third horizontal rib of the housing. Providing an angle on the bottom edge surface of the tapered plates in this area increases the side force on the movable plates during the application of a buffing shock to the draft gear assembly.

  • Publication number: 20050064127
    Abstract: A manufacturing machine assembly and associated method for producing a coupon card. The machine assembly includes a support frame with a printing station for printing indicia on a top surface of a continuous sheet of stock in two parallel rows that define a first strip and a second strip of the stock. A forming station removes a release liner from the first strip to expose an adhesive layer. The forming station also moves the adhesive layer of the first strip into a bonded relationship with the release liner of the second strip to mate the first and second strips and form a continuous series of two-sided coupon cards. Exit rollers completely cut through the series of two-sided coupon cards for forming and separating individual coupon cards from the continuous sheet of stock. A first take-up roller collects a first continuous web of scrap stock.

  • Publication number: 20040231038
    Abstract: A fill control for a toilet tank of the type having a water supply, a fill valve operable to allow water from the water supply to enter the toilet tank, and a float control for the fill valve for closing the fill valve when the float control reaches a full position representing a full condition of the toilet tank, the fill control comprising: a float control override coupled to the float control and having an inactive condition allowing the float control to operate in a conventional way, and an active condition retaining the float control in the full position; and means for selectively retaining the float control override in the active condition. This invention is of particular utility when a first person is utilizing toilet facilities while a second person is utilizing adjacent shower facilities, thereby preventing toilet tank refilling and the undesirable resulting shower water temperature increase.

  • Patent number: 5432046
    Abstract: Provided herein is a brushgraining process to improve the quality of lithographic printing plate substrate surfaces. In the process, the surface is brushed in an aqueous slurry comprising a mixture of particulates of alumina and quartz in a weight ratio range 95:5 to 5:95, with the particulates being in the size range of 1-20 microns. Such a process surprisingly lessens the number of scratches produced on the substrate surface than when compared to using alumina alone or quartz alone or a mixture of alumina and quartz with particle sizes higher than the range disclosed.
