Abstract: A method for replacing a fuse casing (4), which is riveted to the casing (2) of an active component (1) containing an explosive charge (3). The new fuse casing (4) laser-welded to the remaining rivet parts (5) of the active component casing (2). Welding filler materials are used to attach the new fuse casing (4) easily and securely to the active component casing (2), such that the connection can withstand even high firing accelerations, without this resulting in impermissibly high thermal stress to the explosive charge (3) in the active component. Welding powders (7) or welding pastes can be used as welding filler materials, which are inserted into gaps (8) remaining between the remaining rivet parts (5) and the bores (6) in the fuse casing (4) before the remaining rivet parts (5) are welded to the fuse casing (4). Also used are discs (9) that cover the bore holes (6) in the fuse casing (4). The disks are placed onto the frontal faces of the remaining rivet parts (5) and are welded to these.

Abstract: The subject of the invention is a multi-stage process for the production of narrowly-distributed gas-filled microcapsules. In one process step, polymerization of the shell-shaping substance(s) takes place, and in a process step that is separated from it in space and/or time, the formation of the microcapsules by a build-up process takes place. The build-up process is carried out by low-energy defined gas input of the gas that is to be encapsulated with the aid of a porous membrane that has small defined pore openings.
