blade 356 will cooperate with shredder plate 360 to pulverize secondary component 318 which is forced through shredder plate 360 by piston 344 and compression spring 348 fig1 d illustrates a sacrificial secondary reservoir having a hollow cylindrical plug or lining 364 made from solid secondary component such as potassium carbonate lining 364 has a number of integral internal splines 368 lining 364 is formulated and processed so that flowing primary component will cause lining 364 to be eroded and entrained in the flowing primary component with a composite fire suppressant reservoir it is generally not possible to weld the initiator conductor conduit extending from an upper portion of the reservoir to a lower portion of the reservoir to the reservoir itself however with the axially compliant conduit illustrated in fig1 this problem is avoided while permitting the initiator conductor to be protected against damage conduit 384 is inserted into reservoir 18 after the pressure vessel shell in this case the outer wall of reservoir 18 has been fabricated this process begins with insertion of conduit 384 into the interior of reservoir 18 through assembly port 378 installation of conduit 384 continues with placement of the conduit 39 s upper end 384 a into an upper conduit port formed in wall 18 a then axial compliance section 388 which is illustrated in fig1 as a bellows is compressed sufficiently to allow lower end 384 b of conduit 384 to be inserted to a lower conduit port located in lower wall 18 b conduit 384 is then permitted to expand axially then.
