Abstract:
This disclosure relates generally to cartridges for use in projectile-launching devices, such as ammunition cartridges, flare cartridges, and the like, including components of the cartridges, and methods for their manufacture. For example, the cartridges of this disclosure can be ammunition cartridges such as shotshell cartridges, which include an obturating medium which functions to seal the compressed but expanding hot gases and can be used without a pre -formed gas seal.
Abstract:
Herein we describe cartridges, including for shotgun shells, utilizing a particulate obturating medium to provide a gas seal. The obturating medium comprises particles having an average particle size greater than 212 microns, and an average specific gravity greater than 1.1. Such cartridges are particularly useful as shotshell cartridges used as blanks, less lethal loads, hunting loads, target loads, and barrel-cleaning loads. Methods for loading and use are described, as well as different particulate obturating media.
Abstract:
This disclosure provides for payload delivery systems and cartridges and methods that incorporate these payload delivery systems. In one aspect, the payload delivery system can comprise a payload cup and a pleated cup nested within the payload cup and having a pleated side wall. The disclosed cartridges can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.
Abstract:
This disclosure relates to self-contained cartridges and launcher systems for discharging or launching payloads to downrange targets, and methods of attenuating or offsetting recoil when activating such cartridges. Examples of payloads that can be deployed with the disclosed launcher apparatus include chemical, biological, pyrotechnic, marker, tracer, signaling, non-lethal, explosive, smoke, and similar payloads.
Abstract:
This disclosure provides for payload delivery systems and cartridges and methods that incorporate the payload delivery systems. The payload delivery system can comprise a stabilizer having a longitudinally cut side wall defining a series of vanes that are folded forward in the pre-launched configuration. Cartridges that include the payload delivery system are disclosed, which can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.
Abstract:
This disclosure relates to launchers and launcher systems for discharging or launched payloads to downrange targets, and the methods of attenuating or offsetting recoil in such launcher systems. Examples of payloads that can be deployed with the disclosed launcher apparatus include chemical, biological, pyrotechnic, marker, tracer, signaling, non-lethal, explosive, smoke, and similar payloads.
Abstract:
This disclosure relates to cartridges, including shotshell cartridges, for launching multiplex projectile loads that contain different sizes or types of projectiles, and methods of loading the cartridges. In one aspect, for example, the present cartridges can contain an obturating component adjacent the cartridge propellant, a first payload adjacent the obturating component, a separating component adjacent the first payload, and a second payload adjacent the separating component. Shotshells of this configuration in which the first (aft) payload comprises birdshot and the second (forward) payload comprises buckshot are particularly useful.
Abstract:
This disclosure provides for payload delivery systems and cartridges and methods that incorporate the payload delivery systems. The payload delivery system can comprise a stabilizer having a longitudinally cut side wall defining a series of vanes that are folded forward in the pre-launched configuration. Other aspects combine a payload cup nested within the forward folding stabilizer. Still other aspects integrate the payload portion and the stabilizer portion into a single piece that constitutes a stabilized payload cup. The disclosed cartridges can be used to deliver payloads such as solid projectiles, shot of all sizes, powders, gels, liquids, and other payloads to exploit their specific function.

Abstract:
Herein we describe barrel-cleaning cartridges which can be loaded into a firearm and then fired to perform the task of cleaning the barrel of said firearm. The barrel-cleaning cartridges include a propellant, a flexible textile that assumes a general cup shape within the cartridge, and a particulate obturating media, some of which is encircled by the flexible textile. These components combine to form a good gas seal and to clean the barrel of a firearm, including elements of the barrel having variations in diameter. The obturating media comprises particles having an average particle size greater than 212 microns, and an average specific gravity greater than 1.1, and a hardness of less than 7 on the Mohs scale.
