Title: Reel pulse detection apparatus for vcr
Inventor: LEE BYONG-HUI
IPC: G11B15/08
Filed: 1992-04-08
Granted: 1994-04-25
Abstract: Comparing an integral average value with a newly input value, this method enables to check a lebel variation and a duty of reel pulse. After initial clearing, the method converts an average value to a changed lebel initial value [-V(n) , increases the counter number by one, and calculates an analog/digital sample value [-V(n) . Subtracting this value from an average value -V(n-1), when an absolute value of upper value is less than a reference lebel difference, and a limit time is less than pulse width, then the process automatically stops. When a chattering check limit value is less than the counter value for checking, then a flag X is set and the remainder of tape is determined.

Title: Process for heating the column for distillation of the C3 fraction from an fcc unit by means of a circuit of water heated by streams belonging to units placed upstream and/or downstream of the fcc uni

Abstract: The present invention describes a process for heating the reboiler of the propane/propylene separation column situated downstream of an FCC unit and fed with the C3 cut from said FCC unit, a process consisting of heating the water in a hot water circuit by means of one or more process fluids originating from units placed upstream and/or downstream of the FCC unit and called hot fluids, one of these fluids being constituted by the overhead vapours from the fractionation column connected to the mild hydrocracking unit. - Figure 1 to be published
