Abstract : The patent application relates to a passive impulse gage, having a spring loaded mass responsive to impulses and extraneous loads in nuclear tests. The gage has a locking device to prevent reverse motion of the mass. A scribe mechanism has two spring loaded marking pins for marking a scribe plate. When the motion of the mass stops, the marking wheel is permitted to rotate to move one marking pin out of engagement with the scribe plate and to move the other marking pin into engagement with the scribe plate. Thus the indication due to the test impulse is displaced on the scribe plate from indications due to extraneous loads.
