Abstract

The invention relates to the marking and identification of ammunition cartridges. An annular plate (10) with two conductive rings (11, 12), which are separated by a resistive portion (13), is applied on a base plate (3) of an ammunition cartridge (1). The resistance between the two rings (11, 12) identifies the type of ammunition which the cartridge (1) contains. The base plate (3) may also be provided with contact rings (5), (6), (7), which are in electrical contact with the interior of the cartridge. <IMAGE>

Description

508 648 avkänner det resistansvärde som resistansringen inför mellan spetsarna. 508 648 senses the resistance value that the resistance ring introduces between the tips.

Baserat på de egenskaper som den identifierade ammunitionstypen representerar, ges kanonen i vilken identifieringen sker lämplig inställning, Identifiering utförs av en isolerad patron åt gången i nära anslutning till dess aktivering. Ändamålet med föreliggande uppfinning är att åstadkomma en enkel identifiering av ammunitionspatroner som inte kräver att patronhylsans mantelyta är åtkomlig, som medger att befintliga ammunitionspatroner lätt kan modifieras och som kräver ett minimum av komponenter.Based on the characteristics that the identified type of ammunition represents, the cannon in which the identification takes place is given the appropriate setting. Identification is performed by an isolated cartridge at a time in close proximity to its activation. The object of the present invention is to provide a simple identification of ammunition cartridges which do not require the sheath surface of the cartridge case to be accessible, which allow existing ammunition cartridges to be easily modified and which require a minimum of components.

Härigenom medges bl a att ammunitionstypen för var och en av ett ﬂertal i grupp parallellt anordnade patroner med bottenplattorna i ett gemensamt plan samtidigt kan göras åtkomliga för bestämning av typ av ammunition.This allows, among other things, that the type of ammunition for each of a number of cartridges arranged in groups in parallel with the base plates in a common plane can at the same time be made accessible for determining the type of ammunition.

Uppfinningsändamålet uppnås genom ett förfarande kännetecknat av att en kontaktytsfri del av bottenplattans utsida förses med en ringformad identifieringsplatta innefattande två konduktiva ringar separerade av åtminstone ett resistivt element, varvid den elektriska resistansen åstadkommen medelst nämnda resistiva element mellan nämnda konduktiva ringar ligger inom ett förutbestämt resistansintervall valt ur ett ﬂertal olika specifika resistansintervall som är tilldelade olika ammunitionstyper och att resistansen avkännes mellan de konduktiva ringarna och den avkända resistansen jämföres med de nämnda specifika resistansintervallen för identifiering av ifrågavarande ammunitionstyp, en ammunitionspatron kännetecknad av att en ringformad identifieringsplatta innefattande två konduktiva ringar är anbringad på utsidan av ammunitionspatronens bottenplatta. vilken ringformad platta mellan de två konduktiva ringarna uppvisar ett resistivt parti som är indikativt för den typ av ammunition som patronen inrymmer eller avses inrymma, samt en ammunitionsidentifierande platta kännetecknad av att plattan är ringformad och innefattar två konduktiva ringar separerade av ett resistivt parti.The object of the invention is achieved by a method characterized in that a contact-free part of the outside of the bottom plate is provided with an annular identification plate comprising two conductive rings separated by at least one resistive element, the electrical resistance achieved by said resistive element between said conductive rings being predetermined. a number of different specific resistance intervals assigned to different types of ammunition and that the resistance is sensed between the conductive rings and the sensed resistance is compared with the said specific resistance intervals for identification of the type of ammunition, an ammunition cartridge characterized in that an annular identification plate is provided of the base plate of the ammunition cartridge. which annular plate between the two conductive rings has a resistive portion indicative of the type of ammunition which the cartridge holds or is intended to accommodate, and an ammunition-identifying plate characterized in that the plate is annular and comprises two conductive rings separated by a resistive portion.

Den ringformade plattans placering i anslutning till övriga kontaktytor i patronens botten medger att plattan kan nås från samma del av den utrustning som patronen är monterad i som övri ga kontaktytor. vilket bl 508 648 a är utrymmesbesparande. På marknaden befintliga ammunitionspatroner uppvisar kontaktytsfria delar i bottendelen som utan större ingrepp kan uppgraderas med ammunitionsidentifiering enligt uppfinningen.The placement of the annular plate in connection with the other contact surfaces in the bottom of the cartridge allows the plate to be accessed from the same part of the equipment in which the cartridge is mounted as other contact surfaces. which, among other things, 508 648 a is space-saving. Ammunition cartridges available on the market have contactless parts in the bottom part which can be upgraded without major intervention with ammunition identification according to the invention.

Den ringformade plattan kan med fördel anbringas genom limning eller klämverkan.The annular plate can advantageously be applied by gluing or clamping action.

Enligt en fördelaktig utföringsform innefattar plattan ett väsentligen isolerande bärskikt på vilket de konduktiva ringarna och det resistiva partiet är anbringade.According to an advantageous embodiment, the plate comprises a substantially insulating support layer on which the conductive rings and the resistive portion are applied.

Enligt ytterligare en fördelakti g utföringsform innefattar plattan ett väsentligen isolerande bärskikt i vilket de konduktiva ringarna och det resistiva partiet är inrymda.According to a further advantageous embodiment, the plate comprises a substantially insulating support layer in which the conductive rings and the resistive portion are housed.

Enligt ännu en fördelakti g utföringsform utgörs det resistiva partiet av flera parallellt mellan de två kontaktringarna inkopplade resistiva element. Det resistiva partiets resistans kan därigenom lätt ändras genom att slå ut ett eller flera resistiva element så att det resulterande resistiva partiet indikerar andra typer av ammunition.According to another advantageous embodiment, the resistive portion consists of several resistive elements connected in parallel between the two contact rings. The resistance of the resistive portion can thereby be easily changed by knocking out one or more resistive elements so that the resulting resistive portion indicates other types of ammunition.

Figure 4 shows a section according to 4-4 in Figure 3, Figure 5 shows a section according to 4-4 in Figure 3 according to an alternative embodiment of the ammunition identifying plate, Figure 6 shows a further example of an ammunition identifying plate according to the invention and figure 7 schematically show a reading and evaluation device.

Ammunitionspatronen 1 enligt figur l och 2 innefattar en cylinderformad del 2 och en bottendel 3. Bottendelen 3 innefattar en platta 4 på vars ena sida ett antal kontaktringar 5, 6, 7 är anbringade. Kontaktringarna liksom en central cirkulär kontaktyta 8 står i kontakt med patronens inre som till 508 648 4 exempel kan inrymma motmedel 9 i form av exempelvis facklor eller remsor. En ringformad platta 10 är fäst mellan bottendelens ytterperiferi och den yttersta av kontaktringarna 5 och kan till exempel utgöras av en folie. Den ringformade plattan kan vara fäst medelst lim, fasthållen genom klämverkan mellan patron 1 och platta 10 eller vara fäst på annat lämpligt sätt.The ammunition cartridge 1 according to Figures 1 and 2 comprises a cylindrical part 2 and a bottom part 3. The bottom part 3 comprises a plate 4 on one side of which a number of contact rings 5, 6, 7 are arranged. The contact rings as well as a central circular contact surface 8 are in contact with the interior of the cartridge which, for example, can accommodate countermeasures 9 in the form of, for example, torches or strips. An annular plate 10 is attached between the outer periphery of the bottom part and the outermost of the contact rings 5 and can for instance consist of a foil. The annular plate may be fixed by means of glue, held by the clamping action between cartridge 1 and plate 10 or be fastened in another suitable way.

Såsom tydligast framgår av figur 3 och 4 är den ringformade plattan försedd med två konduktiva ringar l l, l2 och ett mellanliggande resistivt parti 13 anbringade på ett väsentligen isolerande bärskikt l4. Enligt ett alternativt utförande visat i figur 5 kan de konduktiva ringarna 1 l. 12 och det mellanliggande resistiva partiet 13 vara inrymda i bärskiktet l4 med de konduktiva ringarna kontaktbara i bärskiktets yta.As can most clearly be seen from Figures 3 and 4, the annular plate is provided with two conductive rings 11, 12 and an intermediate resistive portion 13 applied to a substantially insulating support layer 14. According to an alternative embodiment shown in Figure 5, the conductive rings 11, 12 and the intermediate resistive portion 13 may be housed in the support layer 14 with the conductive rings contactable in the surface of the support layer.

Enligt det i figur 6 visade utföringsexemplet utgörs det resistiva partiet av ett flertal resistiva element 15-18. Dessa element är parallellt inkopplade mellan de två konduktiva ringarna l 1,12. Genom att slå ut ett eller flera av dessa resistiva element l5-l8. ändras den resistans som en avläsnings- och utvärderingsanordning 20 avkänner och därmed till resistansen kopplad ammunitionstyp. Ett utslaget resistivt element uppträder i detta sammanhang som ett ledningsbrott.According to the exemplary embodiment shown in Figure 6, the resistive portion consists of a plurality of resistive elements 15-18. These elements are connected in parallel between the two conductive rings 1.12. By knocking out one or more of these resistive elements l5-l8. changes the resistance that a reading and evaluation device 20 senses and thus the type of ammunition connected to the resistance. A knock-out resistive element appears in this context as a wire break.

Figur 7 visar scheinatiskt en avläsnings- och utvärderingsanordning 20 för avkänning av resistansen mellan de två konduktiva ringarna. En avläsningsenhet 2l är försedd med en första avkänningselektrod 22 kopplad till den ena konduktiva ringen 1 l och en andra avkänningselektrod 23 kopplad till en den andra l2 av de två konduktiva ringarna. Avkänningsenheten arbetar enligt någon av de principer som är kända för resistansbestämning och avger ett resistansvärde. I ett minne 25 finns lagrat resistansintervall för olika ammunitionstyper. Genom att jämföra det av avkänningsanordningen avkända resistansvärdet med i minnet 25 lagrade resistansintervall medelst en jämföraranordning 26 kan förhandenvarande resistansintervall fastställas och därmed med intervallet sammanhängande ammunitionstyp.Figure 7 schematically shows a reading and evaluation device 20 for sensing the resistance between the two conductive rings. A reading unit 21 is provided with a first sensing electrode 22 connected to one conductive ring 11 and a second sensing electrode 23 connected to one the second 12 of the two conductive rings. The sensing unit operates according to one of the principles known for resistance determination and emits a resistance value. A memory 25 contains stored resistance ranges for different types of ammunition. By comparing the resistance value sensed by the sensing device with resistance intervals stored in the memory 25 by means of a comparator device 26, the available resistance interval can be determined and thus with the interval associated ammunition type.
