Abstract: There is disclosed an energy absorption device comprising a plurality of pillars mountable to a ceiling of a hull, each pillar having a fixed portion and a movable portion, the movable portion slidable relative to the fixed portion; a deformable material disposed between the fixed portion and movable portion such that the deformable material resist the sliding movement of the movable portion in one direction; the deformable material further adapted to permanently deform when a blast energy is directed towards the ceiling; and a seat assembly attached to the movable portion, the seat assembly adapted for an occupant.

Abstract: An articulated vehicle is made up of two independently moveable vehicle bodies, for instance tracked vehicle bodies. The first vehicle body has an engine and the second one has a motor/generator. An articulation device connects them to allow the first vehicle body to drive the second vehicle body or vice versa or even for them to act together. A drive transmission that can be used in the vehicle allows power to be input from two shafts or for one of the shafts to be an additional power output. An articulation device that can be used in the vehicle allows quick alignment and/or coupling and decoupling of the two bodies.

Abstract: A firing apparatus (1.0) for a projectile-firing weapon of the type comprising a barrel (8) having a bore therein, the firing apparatus comprising a breech assembly (2.0) adapted to be secured to the barrel (8), a firing mechanism (5.0) adapted to initiate firing of the projectile from the bore, and a valve means (4.0)adapted to allow air within the bore, between the projectile and the firing mechanism (5.0), to be expelled from the bore during loading of the projectile through the bore.
