This class covers also means for practice and training which may have aspects of simulation, e.g. in apparatus for so-called "military games", although simulators are generally covered by class Fulltext... Hierarchy... Expanded...G09.
In this class, the following terms or expressions are used with the meanings indicated:
"semi-automatic firearm" means a firearm from which one shot is fired after actuation of the trigger and which then returns to a condition for firing a subsequent shot upon renewed actuation of the trigger;
"automatic gun" means a gun which will continue firing so long as the initial firing pressure is maintained on the trigger; alpha
"sighting" means bringing into visual coincidence a direction defined by a so-called "sighting" device with the direction of a target;
"aiming" means bringing a weapon to a direction differing from the sighting direction by corrections in order that the projectile may hit the target;
"laying" means setting a weapon in the correct position for hitting a mark.
Attention is drawn to the definitions of "projectile", "missile" and "rocket" given in Note (2) following the title of class Fulltext... Hierarchy... Expanded...F42. [4]
