Note(s) In this class, the following terms are used with the meanings indicated: "Semi-automatic firearm" — 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" — a gun which will continue firing so long as the initial firing pressure is maintained on the trigger. "Sighting" — bringing into visual coincidence a direction defined by a so-called "sighting" device with the direction of a target. "Aiming" — bringing a weapon to a direction differing from the sighting direction by corrections in order that the projectile may hit the target. "Laying" — setting a weapon in the correct position for hitting a mark. (not applicable in English). "ammunition" covers expulsion charge and projectile, whether or not forming a single body, unless otherwise made clear Although simulators are generally in class Fulltext... Hierarchy... Expanded...G09, provision is included in class Fulltext... Hierarchy... Expanded...F41 for means for practice and training which may have aspects of simulation, e.g. in apparatus for so-called "military games".
