Abstract: An ammunition sealing system includes a case hanging rail for holding a row of cases and one or more heating elements in close proximity to the row of cases. The one or more heating elements are configured to heat sealant applied inside the case mouths. The one or more heating elements are one or more induction heating elements or microwave heating elements.

Abstract: A method of sealing and securing of a shaped charge comprising a casing having a detonator, an explosive filler disposed within the casing having a cavity formed therein, and a liner disposed over the explosive filler. The method includes coating at least one portion of the shaped charge with a curable sealant, and exposing the curable sealant to radiation to cure the curable sealant. The radiation may be in the ultraviolet range and have a wavelength in a range of from about 200 to about 400 nanometers. In addition, the at least one portion of the shaped charge that is coated with the curable sealant may be a surface of the liner, a joint between the liner and the casing, over the detonator, or any combination thereof. The liner may comprise a metallic liner.

Abstract: A method of coating a shaft seal for use with rotating parts is disclosed. The method includes providing a shaft seal having an annular shell and an inner lip concentrically spaced inward from an outer surface of the annular shell. The method also includes providing an ultraviolet (UV) coating, printing the UV coating to the outer surface of the annular shell, and exposing the UV coating on the outer surface of the annular shell to UV and other radiation. In addition, the method may include installing the shaft seal around a shaft.

Abstract: A method of achieving controlled, variable ballistic dispersion in an automatic weapon is disclosed includes providing a plurality of cartridges, where each cartridge has a case and a projectile partially inserted into a mouth of the case forming a circumferential joint between the projectile and the mouth of the cartridge and held therein at a different pull strength. The method also includes providing a plurality of adhesive sealants, where each adhesive sealant of the plurality of adhesive sealants sets a design bullet pull strength that is different from each other adhesive sealant.

Abstract: A non-contact jet valve applicator is used to inject sealant into a joint of an ammunition cartridge, including a circumferential case mouth joint and/or primer cup joint. A sealant is selected with adhesive properties to set a pull strength of the cartridge. In a crimped cartridge, the pull strength set by the adhesive sealant is greater than a pull strength otherwise generated by the crimp.

Abstract: A system for printing a bullet tip identification includes a bullet support apparatus for holding and rotating a bullet about its longitudinal axis and a print head configured to be positioned in close proximity to a tip of a bullet. The print head is configured to apply an identification around the circumference of the bullet tip while the bullet is rotating about its longitudinal axis. A method of applying identification marks on bullet tip includes positioning a bullet tip in close proximity to a print head and rotating the bullet about a longitudinal axis of the bullet. An identification mark is then applied around the circumference of the bullet tip by the print head as the bullet rotates.

Abstract: The invention relates to an identifiable bullet and methods for making an identifiable bullet. In one embodiment, the bullet has a generally circumferential body that tapers from a rearward end toward a forward end. A generally circumferential bore extends from an orifice on the forward end into the body at least part of the way between the forward end and the rearward end. The end of the bore opposite the orifice includes a polymeric material support surface. A polymeric material is placed between the polymeric material support surface and the forward end. The polymeric material may include a user identifiable marker for allowing a user to identify the bullet when viewing the forward end. Alternatively, the polymeric material may cover a user identifiable marker and seal the user identifiable marker in the bore. A user may identify the bullet by viewing the marker from the forward end of the bullet.
