摘要： This invention relates to a fume extractor (10) for extracting fumes from a bore (12) of a barrel (14) of a gun and comprising an annular main reservoir (16); an annular inlet reservoir (18).; and an annular auxiliary reservoir (20), all concentrically surrounding the barrel (14) and being in communication with each other and the bore (12). The inlet reservoir (18) is sandwiched between the main reservoir (16) and the barrel (14). The auxiliary reservoir (20) is sandwiched between the main reservoir (16) and the barrel (14) and is located adjacent the inlet reservoir (18) on a muzzle brake end thereof. The arrangement is such that the main reservoir (16) is pressurised when the gun is fired and such that the fumes in the bore (12) are extracted by the release of pressure in the main and auxiliary reservoirs (16) and (20), after the projectile has left the barrel (14). The communication between the inlet reservoir (18) and main reservoir (16) consists of plurality of ports (24) distributed circumferentially each port being provided with a check valve (30).

摘要： This invention relates to a gun tube support assembly (10), which comprises four support sections (12) arranged annularly around a gun tube (13) and received in an opening in a cradle (15) of a gun. Each support section (12) comprises a bush housing (14), a cradle bush (16) and a damping means sandwiched between the bush housing (14) and cradle bush (16). The damping means is in the form of a rubber pad (18) made of relatively high-temperature silicon rubber. The rubber pad (18) includes a plurality of protrusions 18.1 extending from a face of the pad (18) for abutting an outer surface of the cradle bush (16). The protrusions (18.1) accommodate compression of the pad (18), the arrangement being such that the rubber pad (18) absorbs and dampens kinetic energy emanating from the gun tube (13) during firing of a projectile.

摘要： The invention relates to a charge retaining mechanism (10) for retaining a charge (12) inside a chamber (14) of a barrel (16) of a gun, comprising retaining members consisting of a central retaining member (18.1) and two sets of end retaining members (18.2), extending from an elongate coil spring (20), into the chamber (14). The coil spring (20) is located in an elongate groove formation (22) cut into the inner surface of the barrel (16) and extending partially around the inner circumference of the barrel (16). The charge retaining members (18.1, 18.2) are movable between a charge passing position and a charge retaining position and are biased in the direction of the charge retaining position by means of the coil spring (20).

摘要： This invention relates to an ammunition loading assembly (10) for loading a projectile (12) into a barrel (14) of a gun comprising an urging member (16) for urging the projectile (12) into the said barrel (14). The assembly (10) further includes a drive means (18) for driving the urging member (16) between a projectile receiving position outside the barrel (14) and a projectile delivery position inside the chamber (20) of the gun. The drive means (18) includes a drive chain assembly (22), for driving the urging member (16) between the projectile receiving and delivery positions. The drive chain assembly (22) is rigid in all directions but one, the arrangement being such that the drive chain assembly (22) pushes the urging member (16) from the projectile receiving position to the projectile delivery position and pulls the urging member (16) from the projectile delivery position to the projectile receiving position. The assembly further includes first and second chain-retaining devices (42, 44) for limiting curving of the chain assembly and guiding the chain when moving out of the magazine.

摘要： This invention relates to a trunnion assembly (10) comprising a trunnion shaft (12) and a housing (14) defining a bore (16) for rotatably and concentrically receiving the trunnion shaft (12). The trunnion assembly (10) further includes a bearing assembly (18) located inside the housing (14) and surrounding the trunnion shaft (12). The bearing assembly (18) allows rotation of the shaft (12) in the bore (16) whilst also allowing movement of the shaft (12) out of concentric alignment with the bore (16). The bearing assembly (18) includes a toroidal-type roller bearing assembly (20), which allows for misalignment of the shaft (12) inside the bore (16). The bearing assembly (18) further includes a re-aligning means that re-aligns the longitudinal axis B of the shaft (12) with the longitudinal axis C of the bore (16), after the said misalignment.
