His design consulting work on firearms suppressors persuaded him that while existing compensator
designs obviously worked better than nothing, there was considerable room for improvement.
The only "authorized for Navy use" (ANU) buoyancy compensator
affected by this recall is the IDI "Advantage" (Affected date codes are October 2000 through June 2001).
For Sauer-Sunstrand, the result is two remanufactured Cincinnati 340-20 Twin Grip centerless grinders, adapted with AirTronics precision Inchworm compensators
proved effective in keeping recoil and muzzle flip to a minimum, and I was rewarded consistently by hearing the bell-like ring of my shot hitting the target.
While certified divers need to learn to control their own buoyancy compensator
, since this was an introductory dive, Sadler would swim by my side and do that for me.
Reference  introduces the concept of fixing the frequency by adjusting the hysteresis threshold from the output of a compensator
that processes feed-forward input reference signals or feedback PWM signals.
With the efficient compensator
I didn't find recoil or muzzle jump objectionable at all.
This confines the major portion or the pressure differential across the valve to the compensator
and keeps fluid pressure differential across the spool low, resulting in low shifting forces.
By replacing the 100,000-ohm resistor of the thermal emf compensator
with one of higher or lower resistance, the number of microvolts per angular degree of rotation of the slider can be varied to suit the needs of the particular galvanometer and its environment.
The procedure for measuring birefringence using a compensator
is a standard test method described in ASTM D 4093.
Functionally, what a compensator
actually does is trap a portion of the gases following the bullet as it exits the barrel (what you would normally see as the flash exiting the barrel when firing), venting a good portion of these gasses upward because the compensator
has a closed bottom like a cup.
The silencer-like compensator
is arguably the most lethal-looking accessory.
