Title: An adaptive, on line, statistical method and apparatus for motor bearing fault detection by passive motor current monitoring
Inventor: YAZICI BIRSEN
IPC: G01M13/04
Filed: 1997-05-01
Abstract: A motor current signal is monitored during a learning stage and divided into a plurality of statistically homogeneous segments representative of good operating modes. A representative parameter and a respective boundary of each segment is estimated. The current signal is monitored during a test stage to obtain test data, and the test data is compared with the representative parameter and the respective boundary of each respective segment to detect the presence of a fault in a motor. Frequencies at which bearing faults are likely to occur in a motor can be estimated, and a weighting function can highlight such frequencies during estimation of the parameter. The current signal can be divided into the segments by dividing the current signal into portions each having a specified length of time; calculating a spectrum strip for each portion; and statistically comparing current spectra of adjacent ones of the strips to determine edge positions for the segments. Estimating the parameter and the boundary of each segment can include calculating a segment mean (the representative parameter) and variance for each frequency component in each respective segment; calculating a modified Mahalanobis distance for each strip of each respective segment; and calculating the modified Mahalanobis mean and the variance for each respective segment. Each modified Mahalanobis mean can form a respective radius about a respective segment mean to define a respective boundary.

Abstract: The   effervescent   system   for   effervescent tablets and/or effervescent granules contains,  on the one hand,  particles of a solid,  edible,  organic acid and,  on  the  other hand,  particles  of  at  least  one alkali  metal  bicarbonate,   of  which  at  least  1, preferably from 2 to 4, but at most 10, preferably at most 8,  % by weight are superficially converted into dry   alkali   metal   carbonate   free   of   water   of crystallization. The acid particles, preferably citric acid particles, can be covered in a manner known per se by partial reaction with at least one carbonate and/or bicarbonate, preferably from about 20 to 40% by weight thereof.  The conversion mentioned is carried out by a procedure in which commercial alkali metal bicarbonate particles are heated in a vacuum vessel at less than 40,  preferably less than 20,  in particular less than 10,  mbar at above  60~C,  preferably between 80~C and 120~C, in particular at about 100~C, and are cooled to below  60~C,  preferably  to  below 50~C,  after  a  time predetermined  by  the  desired  layer  thickness,  while maintaining  the vacuum.   The  alkali metal  carbonate particles evolve only a little CO2 even on storage at elevated  temperature,  and  the  formation  of  free salicylic  acid  (fSA)  from  any  acetylsalicylic  acid mixed with the effervescent system remains very small.
