Single-trip containers

Suction probe. Potentially any but may be cumbersome with small single trip containers. Requires special closure. None commercially in UK and Europe. ChemProbe in USA. Position and handling of probe shroud is critical. May not fail safe. Not good for rinsing the pesticide container. 

Systems based on standard single trip containers. Potentially any. Systems often rely on presence of a foil seal so as to remain closed while an alternative closure is fitted. Wisdom system. Contents withdrawn in measured amounts. Container inverted in system. Can also be used with keg type containers. 

However, a series of factors introduce losses in the system namely, the reflectivities of the mirrors (RiandR2) on the figure, which reflect only a fraction, Ri and R2, of the intensity. Additional losses can be produced by absorption in the windows of the cell that contains the active medium (if this is the case), diffraction by apertures, and scattering due to particles or imperfect surfaces. All of those losses can be included in a loss factor per trip, expressed as e. Thus, considering both amplification and intensity decrease per round trip, the intensity after a single round trip through a resonator of length d is... 

The use of coincidence and fixed limit trips cem minimize these practices. Section VIII contains a special report in its entirety, HW-7565T "Logic For Reactor Safety Circuit Systems", which objectively discusses the relationship of continuity of operation and nuclear safety as system logic (multiple channel monitoring of a single parameter point) is applied to Reactor Safety Circtiits and Safety...
