Claims (10)
1. Patronhylster (2) til eksplosive materialer (6, 8) omfattende en løsbar grundplade (4) anbragt i en bundsektion (3) af patronhylsteret (2) og en grundpladelåsemekanisme (25) omfattende et temperaturafhængigt formhukommelsesmateriale (13) indeholdt i et rum (12; 20), hvor formen af formhukommelsesmaterialet (13) er temperaturafhængigt, således at formhukommelsesmaterialet (13) genindtager en tidligere form over en forudbestemt kritisk temperatur ved at forskydes radialt indad (17) i rummet (12; 20), kendetegnet ved, at formhukommelsesmaterialet (13) er indrettet til at udøve en brudkraft på grundpladen (4) eller på bundsektionen (3) af patronhylsteret (2), når det bevæger sig radialt indad under en temperaturstigning, der overstiger den kritiske temperatur, for derved at bryde forbindelsen mellem grundpladen (4) og bundsektionen (3) af patron hylsteret (2) og frigøre grundpladen (4) fra bundsektionen (3) af patron hylsteret (2).
2. Patronhylster ifølge krav 1, kendetegnet ved, at formhukommelsesmaterialet (13) er indrettet til at udøve en brudkraft på grundpladen (4).
3. Patronhylster ifølge krav 2, kendetegnet ved, at grundpladen (4) har brudindikatorer (16) til at lette opbrydningen af forbindelsen mellem grundpladen (4) og bundsektionen (3) af patron hylsteret (2).
4. Patronhylster ifølge krav 3, kendetegnet ved, at brudindikatorerne (16) omfatter en V-formet reces i periferien af grundpladen (4).
5. Patronhylster ifølge ethvert af de foregående krav, kendetegnet ved, at formhukommelsesmaterialet (13) er anbragt i et rum (12) mellem grundpladen (4) og bundsektionen (3) af patronhylsteret (2).
6. Patronhylster ifølge krav 1, kendetegnet ved, at formhukommelsesmaterialet (13) er indrettet til at udøve en brudkraft på bundsektionen (3) af patron hylsteret (2).
7. Patronhylster ifølge krav 6, kendetegnet ved, at bundsektionen (3) af patronhylsteret (2) har brud i ndi kato rer (24) til at lette opbrydningen af forbindelsen mellem grundpladen (4) og bundsektionen (3) af patron hylsteret (2).
8. Patronhylster ifølge ethvert af kravene 1, 6 eller 7, kendetegnet ved, at formhukommelsesmaterialet (13) er anbragt i bundsektionen (3) af patronhylsteret (2).
9. Patronhylster ifølge krav 8, kendetegnet ved, at bundsektionen (3) af patronhylsteret (2) i forbindelse med formhukommelsesmaterialet (13) i en retning indad er dimensioneret med en tyndere materialeforlængelse end indadrettede dimensioner af tilstødende dele af bundsektionen (3).
10. Ladning (1) af ammunition omfattende et patronhylster (2) ifølge ethvert af de foregående krav.
