A pyrotechnical ignition system with integrated ignition circuit for an occupant restraint system for motor vehicles includes electrical components for triggering or communication functions integrated therein, a capacitor arrangement, having a flat non-conductive external surface is used as a substrate or carrier element on which the other components are directly arranged and carried. A conductor structure linking the components can be formed by insertable metal parts that are arranged in the housing and project into the holding chamber in which the capacitor arrangement and the circuit component are arranged, and make contact with contact zones on the upper side of the circuit or the capacitor arrangement. The conductor structure may be a printed-conductor structure that is precipitated on non-conductive external surfaces of the capacitor arrangement, and the lateral surfaces thereof, connect the upper and the lower sides of the ignition capacitor as well as the individual capacitor electrodes within the capacitor arrangement to form one or several capacitors, in particular the ignition capacitor. The ignition bridge layer is situated on the capacitor arrangement or on the circuit.

A device as claimed in claim 6 wherein each quarter-cylindrical shaped carrier plate comprises at least two semi-circular carrier yokes and, when the shell carrier is in closed mode, downwards facing quarter-cylindrical shaped carrier plates which, as the semi-circular carrier yokes can be displaced along the upwards facing semi-circular carrier sections, can be moved together above the cylindrical space thereby leaving the lower half open. 10. A device as claimed in the method in claim 2 for handling artillery shells in artillery guns that have an integral shell magazine fixed in the traverse system but independent from the elevating mass of a type which on command outfeeds shells one by one with a specific linear velocity in the longitudinal axis of each shell and where each shell after outfeed shall be re-angled to coincide with the angle of elevation of the gun and shall be transferred laterally in relation to its longitudinal axis to the loading position immediately outside the breech ring partly by a loading pendulum designed to pivot around the trunnion centre of the gun and whose task is to overcome the difference in angle between the shell magazine outfeed axis and the angle of elevation of the gun and partly by a shell loading cradle whose task is to overcome the lateral distance between the location of the shell magazine outfeed aperture and the breech ring wherein the device comprises both the loading pendulum, pivotable around the trunnion centre of the gun and equipped with a shell carrier and the brake module that is mechanically independent of the loading pendulum and is initially aligned with the loading pendulum shell carrier which module operates in initial mode via brake jaws arranged initially in line with the loading pendulum shell carrier. 11. A device as claimed in claim 4 wherein the brake jaws of the brake module are arranged so that they grip each shell fed out ahead of the shell carrier in the outfeed direction. 12.

A device as claimed in claim 7 wherein each quarter-cylindrical shaped carrier plate comprises at least two semi-circular carrier yokes and, when the shell carrier is in closed mode, downwards facing quarter-cylindrical shaped carrier plates which, as the semi-circular carrier yokes can be displaced along the upwards facing semi-circular carrier sections, can be moved together above the cylindrical space thereby leaving the lower half open. 14.

A method as claimed in claim 1 wherein the shells are released in a downward motion from the dedicated brake module. 16. A method as claimed in claim 1 wherein each shell is also translated vertically during transfer to the loading position. 17. A method for handling artillery shells in artillery guns, the method comprising: providing a shell magazine in a traverse system; providing a loading pendulum that pivots about a trunnion center; outfeeding shells through a shell magazine outfeed aperture, wherein the shells have a linear velocity along a longitudinal axis of each shell as they are outfed from the aperture; braking the linear velocity of each shell through a linear distance in a brake module; and transferring each shell to a gun loading position outside a breech ring of a barrel, partly by the loading pendulum that pivots around a trunnion centre of the gun, wherein the loading pendulum pivots the shells to reduce a difference in angle between a shell magazine outfeed axis and an angle of elevation of the gun, and partly by a shell loading cradle that translates the shells toward the gun loading position, and wherein the loading pendulum pivots away from the brake module as it pivots the shells. 18. A method as claimed in claim 17 comprising: releasing the shells in a downward motion from the brake module. 19. A method as claimed in claim 18 wherein outfeeding comprises: feeding shells through a shell carrier connected with the loading pendulum, wherein the shell carrier guides the shells until the linear motion of the shell has been braked to zero, and wherein the shell carrier pivots with the loading pendulum. 20. A method as claimed in claim 18 wherein braking the linear velocity of each shell comprises: operating the brake module in an initial mode wherein brake jaws of the brake module are initially aligned with the loading pendulum shell carrier. 21.
