Title: Coproduction of a normal purity and ultra high purity volatile component from a multi-component stream
Inventor: AGRAWAL RAKESH
IPC: F25J3/04
Filed: 1992-08-04
Granted: 1997-03-25
Abstract: This invention relates to an improved process for the coproduction of a volatile component with normal purity and ultra high purity from a stream containing other heavier components and contaminated with lighter impurities which are more volatile than the volatile component.  The improvement resides in removing a stream of the volatile component which is substantially free of the lighter impurities and then introducing the stream stripped of impurities to a second distillation column for fractionation.  The second distillation column is equipped with a rectification section wherein the stream is rectified and the volatile component obtained in ultra high purity as an overhead.  The volatile component with normal purity is obtained from the first distillation column as an overhead.

Title: On-line dirt counter
Inventor: JORDAN BYRON DALE
IPC: G01N21/89
Filed: 1990-05-23
Granted: 1995-10-24
Abstract: The two-dimensional medium-pass fil-ter principle is used to acquire a sharpened image initially. In practice, the sharpened im-age is obtained from the difference of a linear array signal of a partially out-of-focus image from another linear array signal of the same image but in focus. Integrated intensity of dirt specks higher than a user selected threshold are measured and accumulated. Each integrat-ed intensity value is converted into its corre-sponding speck size with the use of a prede-fined look-up table. The counter generates a dirt speck histogram and statistical data with-in a preselected time interval or area coverage.
