Abstract: A closure wad is placed at the mouth of the launching end of a shotgun cartridge before the mouth is crimped down to seal the launching end of the cartridge. Both the walls of the closure cap and the walls at the mouth of the plastic envelope are crimped down together, thereby forming a substantially impermeable seal at the launching end of the cartridge. In addition, the inventive closure cap substantially reduces the detritus which is sometimes expelled when a launcher cartridge is fired.
Abstract translation: 在将嘴巴压紧以封住药筒的发射端之前，将闭合器置于霰弹枪筒的发射端的口处。 闭合盖的壁和塑料封套口部的壁均被压接在一起，从而在筒的发射端处形成基本上不可渗透的密封。 此外，本发明的封闭盖基本上减少了当发射筒被点燃时有时排出的碎屑。

Abstract: A shot shell such as would be utilized in a shotgun or the like, wherein the cartridge forming the shell has a collapsible extension removably or permanently engaging the shot end of the cartridge, with the cartridge configured to provide a un-compressed length of, for example, 2.50 inches (the minimum length of shell for conventional automatic or semi-automatic, magazine fed shotguns. The collapsible extension is configured to be compressed when placed in a spring-fed magazine, so as to provide increased magazine capacity when compared to standard length shells, while expanding when removed by from the magazine during a loading cycle, so as to facilitate reliable placement of the shell into the breach from the magazine. The collapsible extension in the loaded cartridge of the present invention is configured to be ejected from the barrel upon firing of the cartridge. The present system thereby provides a means to increase the capacity of conventional automatic or semi-automatic (i.e., pump actuated) shotguns, while reducing the likelihood of jamming or malfunction due to utilizing shells which are shorter than the firearm was designed to process.

Abstract: A moisture seal over shot wad for a roll crimped shotshell casing. The seal has a pair of spaced tubular flanges which comprise the rim portion of the disk shaped over shot wad. The tubular flanges are designed to receive the terminal end of the shotshell casing as the roll crimp is formed to frictionally engage the terminal end and seal the casing against the intrusion of moisture.

Abstract: A moisture seal is designed for a shotshell having a biaxially oriented plastic tubular body. The seal is a composite of a thermally conductive layer and a thermoplastic such as high density polyethylene laminated together. The rim portion of the inner layer of high density polyethylene is bonded or fused to the tubular body to seal the shot load end without destroying the biaxial orientation of the tubular body adjacent the rim portion. The moisture seal may be installed inside the tubular body and fused to the inside surface of the tubular wall or may be installed in place of or over the end closure and fused to the outside surface of the tubular body.

Abstract: A container, such as a cartridge case for an illuminant star signal, comprises a molded case of fiberglass reinforced rigid thermoplastic resin possessing a cap of similar but unreinforced resin ultrasonically welded thereto to provide a hermetically sealed unit. Due to the dissimilarity in fiberglass content of the cap and case materials, the cartridge possesses a line of reproducible weakness along the weld line. Signal cartridges of this type are capable of failing reliably along said weld line to achieve a highly reproducible narrow altitude range of star trajectory and reliable star ignition.
Abstract translation: 诸如用于发光体星形信号的盒壳体的容器包括玻璃纤维增强的刚性热塑性树脂的模塑壳体，其具有超声波焊接到其上的类似但未增强的树脂的盖以提供气密密封的单元。 由于帽和壳体材料的玻璃纤维含量不同，筒具有沿焊缝线的可重复的弱线。 这种类型的信号筒能够沿着所述焊接线可靠地失效，以实现星轨迹和可靠的星火点火的高度可重复的窄高度范围。
