Abstract
L'INVENTION EST RELATIVE A UNE CARTOUCHE PERMETTANT D'OBTENIR UN MEILLEUR RENDEMENT DE LA FORCE EXPLOSIVE DE LA POUDRE. ELLE SE CARACTERISE PAR LE FAIT QUE LA POUDRE UTILISEE EST UNE POUDRE COMPRIMEE TELLE QUE CELLE SE PRESENTANT SOUS LE TERME DE "BALL POWDER" ET QUE LE VOLUME DE L'ETUI EST REDUIT D'AU MOINS ENVIRON 10 PAR RAPPORT AU VOLUME DE L'ETUI DES CARTOUCHES STANDARDISEES.THE INVENTION RELATES TO A CARTRIDGE ALLOWING A BETTER YIELD OF THE EXPLOSIVE FORCE OF THE POWDER. IT IS CHARACTERIZED BY THE FACT THAT THE POWDER USED IS A COMPRESSED POWDER SUCH AS THE TERM OF "BALL POWDER" AND THAT THE VOLUME OF THE CASE IS REDUCED BY AT LEAST ABOUT 10 IN RELATION TO THE VOLUME OF THE STANDARD CARTRIDGE CASE.
Description

La présente invention est relative à une nouvelle cartouche qui, par ses caractéristiques particulières, permet d'obtenir, soit une augmentation sensible de la force explosive avec la même quantité de poudre, soit la même puissance de travail avec moins de poudre. Après de nombreuses expériences, le demandeur a en effet constaté que ce résultat pouvait être obtenu, d'une part en choisissant la nature de la poudre utilisée et d'autre part en modifiant les dimensions des étuis de cartouche habituellement The present invention relates to a new cartridge which, by its particular characteristics, makes it possible to obtain either a substantial increase in the explosive force with the same quantity of powder, or the same working power with less powder. After many experiments, the applicant has indeed found that this result could be obtained, on the one hand by choosing the nature of the powder used and on the other hand by modifying the dimensions of the cartridge cases usually
utilisés.used.
La présente invention a pour objet une cartouche permettant d'obtenir un meilleur rendement de la force explosive de la poudre, caractérisée par le fait que la poudre utilisée est une poudre comprimée telle que celle se présentant-sous forme de petits grains ronds et connue des spécialistes sous le terme de ball powder" et que le volume disponible de l'étui est réduit d'au moins environ 10 % par rapport au volume de l'étui des The subject of the present invention is a cartridge making it possible to obtain a better yield of the explosive force of the powder, characterized in that the powder used is a compressed powder such as that occurring in the form of small round grains and known to balloon "and that the available volume of the case is reduced by at least about 10% in relation to the volume of the case.
cartouches standardisées.standardized cartridges.
Conformément à l'invention, l'étui peut être réduit dans sa longueur jusqu'au point o la quantité de poudre dite Uball powder' qui correspond à la charge maximale de la cartouche According to the invention, the case can be reduced in length to the point where the amount of Uball powder 'powder which corresponds to the maximum charge of the cartridge
occupe la totalité du volume de l'étui. occupies the entire volume of the case.
Il est possible ainsi d'obtenir grâce à l'invention une force explosive nettement supérieure avec une même quantité de poudre ou encore d'obtenir la même force explosive avec une It is thus possible to obtain, thanks to the invention, a much higher explosive force with the same quantity of powder or to obtain the same explosive force with a
quantité de poudre inférieure d'environ 10 à 15 %. powder amount of about 10 to 15% lower.
Par ailleurs, le fait de réduire la longueur des étuis permet de réaliser une économie sur le matériau tel que le Moreover, the fact of reducing the length of the cases makes it possible to save on the material such as the
laiton qui les compose.brass that composes them.
Dans le but de mieux faire comprendre l'invention, on va en décrire maintenant plusieurs modes de réalisation pris In order to better understand the invention, we will now describe several embodiments taken
comme exemple.for example.
Un étui de cartouche de calibre 22 5,6/16 possède A 22.5.6 / 16 caliber cartridge case has
d'après les standards actuels, une longueur de 15,5 mm. according to current standards, a length of 15.5 mm.
Conformément à l'invention, on réalise un étui d'une longueur de 14 mm, qui est plus court de 1,5 mm, soit d'environ %. Les essais qui ont été effectués par le demandeur ont montré que la cartouche conforme à l'invention, d'une longueur de 14 mm permet d'obtenir la même force explosive que la cartouche According to the invention, a case 14 mm in length, which is shorter by 1.5 mm, or about%, is produced. The tests which have been carried out by the applicant have shown that the cartridge according to the invention, with a length of 14 mm makes it possible to obtain the same explosive force as the cartridge.

conventionnelle avec un étui de 15,5 mm en utilisant 10 % de conventional with a 15.5 mm case using 10%
"ball powder' en moins."ball powder" in less.
C'est ainsi qu'une charge selon l'invention contient 0,265 grammes de poudre "ball powder' alors que la charge d'une cartouche conventionnelle correspondante en contient 0,300 g Une autre charge contient selon l'invention 0,235 g de poudre alors Thus, a filler according to the invention contains 0.265 grams of powder "ball powder" while the charge of a corresponding conventional cartridge contains 0.300 g Another filler contains according to the invention 0.235 g of powder then
qu'elle en contient 0,260 g dans les cartouches conventionnelles. that it contains 0.260 g in conventional cartridges.
On voit donc, que conformément à l'invention la réduc- It can thus be seen that according to the invention the reduction
tion de la longueur de l'étui permet, à puissance égale, de réduire d'environ 10 % la quantité de poudre utilisée, ce qui constitue une économie non négligeable, non seulement sur la The length of the case allows, at equal power, to reduce the quantity of powder used by about 10%, which is a significant saving, not only on the
poudre mais également sur le matériau qui constitue l'étui. powder but also on the material that constitutes the holster.
Par ailleurs, l'étui étant selon l'invention rempli au maximum par la charge explosive et la chambre d'explosion ayant une longueur qui correspond à celle de l'étui, il est impossible d'utiliser dans l'appareil une charge explosive de puissance supérieure à celle de la cartouche selon l'invention ce qui donne une sécurité importante supplémentaire En effet, une charge de puissance supérieure entraînerait un allongement de l'étui qui ne pourrait plus être utilisé dans un appareil adapté aux cartouches Furthermore, the case being according to the invention filled to the maximum by the explosive charge and the explosion chamber having a length which corresponds to that of the case, it is impossible to use in the apparatus an explosive charge of higher power than that of the cartridge according to the invention which gives an important additional security Indeed, a higher power load would cause an elongation of the holster which could no longer be used in a device adapted to the cartridges
selon l'invention.according to the invention.
1 Il est bien entendu que les modes de réalisation qui viennent d'être décrits ne présentent aucun caractère limitatif et qu'ils pourront recevoir toutes modifications désirables sans It is understood that the embodiments just described are not limiting in nature and that they can receive any desirable modifications without
sortir pour cela du cadre de l'invention. to get out of the scope of the invention.
En particulier, il est clair que la réduction de la longueur de l'étui peut être différente de celle qui a été indiquée. -3- In particular, it is clear that the reduction of the length of the case may be different from that which has been indicated. -3-
