Abstract: A support box apparatus includes longitudinal members that span forward to aft and transverse members that span inboard to outboard between the longitudinal members. The longitudinal members and the transverse members are formed of composite honeycomb sandwich panels. The support box apparatus also includes attachment components configured to couple the longitudinal members or the transverse members to structural components of an aircraft, electrical wiring attached to the longitudinal members or the transverse members, environmental control system (ECS) ducting attached to the longitudinal members or the transverse members, and life support lines attached to the longitudinal members or the transverse members.

Abstract: A hand held pneumatic gun has an airway arranged to be coupled to a source of compressed air, the airway communicating with an air chamber via a trigger valve assembly. The gun includes a detachable breech that is supported in a sealed position against the air chamber by a support ring pivotally secured to the body of the gun. An interlocking assembly is arranged to interlock with the trigger valve assembly if the breech is not supported in its sealed position, so that actuation of the trigger valve assembly is inhibited unless the breech is sealed against the air chamber. The breech incorporates a nozzle that can be secured to an end of a hose or tube and a polymer projectile is placed into the breech to be forced by the air pressure through the hose or tube to clean the interior of the hose or to remove contaminate matter therefrom.
