The encyclopædia britannica; a dictionary of arts, sciences, literature and general information . e glandK the packing employed is a viscous liquid which is in communicationby means of the pipe J with the intensifier I. The latter consistsof a cylinder containing a piston and rod free to move: the frontface of this piston is subject to the pressure of the air in the airchamber, the rear face is in communication with the liquid in thegland. Now, as the piston head is held in position by the pressureson either side of it, and as the effective area of the front face isgreater than that of the rear—on account of the rod—the liquidpressure per square inch of the fluid in the gland, &c, must be greaterthan that of the air in the air chamber, hence the latter cannotescape through the former. The pressure in the chambers F and Gis adjusted on preparing for action by an air pump worked by energy of recoil is further utilized as follows: hydrauliccylinders called compressors are held in the cradle, and in themwork rams connected with the cross-head A (see fig. 85): they are. ^ Fig. 8,5.—Details of Mounting shown in fig. 84 also connected with a hydraulic accumulator (not shown) whichcan be placed in any convenient position in the work, and the powerthus stored up be employed for raising the projectiles, for whichpurpose two lifts are provided. One of these (W) is in the floor ofthe emplacement, the other (W) is attached to and moves with themounting. Underneath and suspended from the circular gun plat- form RR, which forms a shield, is an overhead railway QQ, on whichrun trollies, each taking a projectile. The projectiles are stored inthe recess shown in section at O. By means of a shell barrow anyprojectile can be placed on the lift W and raised to a trolley whichcan be run round over the lift W, which raises the projectile, asshown at S, to a point suitable for loading.
