Title
Titles differ between systems:
IPC: using particles entrained by a fluid stream
CPC: using particles entrained by a fluid stream (G01P5/22 takes precedence)
Full Title
Full titles differ between systems:
Measuring speed of fluids, e.g. of air stream; Measuring speed of bodies relative to fluids, e.g. of ship, of aircraft > by measuring the time taken by the fluid to traverse a fixed distance > using particles entrained by a fluid stream
Measuring speed of fluids, e.g. of air stream; Measuring speed of bodies relative to fluids, e.g. of ship, of aircraft (application of speed-measuring devices for measuring volume of fluid G01F) > by measuring the time taken to traverse a fixed distance > using particles entrained by a fluid stream (G01P5/22 takes precedence)
No child classifications to compare. This is a leaf node in both IPC and CPC.
