41. The secondary demand valve can be a hybrid of a demand valve and a buoyancy compensator inflation valve. 42. The barrel was enclosed into tubular jacket with cooling slots and muzzle brake / compensator at the front. 43. The forward-venting muzzle brake, also described as a linear compensator reduces the perceived muzzle blast. 44. He discovered the " antenna effect " in such systems and invented the capacity compensator for its control. 45. The compensator was extremely effective; it also enabled the user to fire the rifle with one hand. 46. The static compensator lets engineers store reactive power and dump it in quickly if they need to raise voltage. 47. Minimising the volume of gas required in the buoyancy compensator will minimise the buoyancy fluctuations with changes in depth. 48. It scared him so much that he invented and installed a compensator on the muzzle to control the recoil. 49. If a drysuit is worn, it must be equalised by inflation and deflation, much like a buoyancy compensator . 50. The FN Patrol Bolt Rifle is also marketed with a compensator on the muzzle of the rifle's barrel.
