Patent number: 9453714Abstract: Apparatus and methods for manufacturing subsonic ammunition articles from conventional supersonic ammunition articles are provided. The apparatus includes devices for controllably introducing a filler material to reduce the inner volume of a conventional supersonic ammunition article. Method are also provided for converting a conventional supersonic ammunition article to a subsonic ammunition article including defining a new subsonic propellant volume within said conventional supersonic ammunition article and controllably introducing a filler material therearound.Type: GrantFiled: April 6, 2015Date of Patent: September 27, 2016Assignee: MAC, LLCInventors: John Francis Bosarge, Nikica Maljkovic

Patent number: 9395165Abstract: A subsonic ammunition cartridge casing having an engineered internal volume designed to allow for the introduction of precisely the amount of propellant necessary at precisely the desired location to reproducibly produce the desired projectile velocity and internal pressure is provided. The subsonic shell casing has an engineered internal propellant cavity built into the internal body of the casing itself that does not necessarily depend on the introduction of a separate volume reducing device such as tubing, filler, foam filler and the like. This ensures the integrity of the case, does not result in anything being expelled through the muzzle of the weapon other than the projectile, does not have any burning or combusting components, allows for very precise control of the internal volume and thus chamber pressure, and is economical to produce.Type: GrantFiled: October 6, 2015Date of Patent: July 19, 2016Assignee: MAC, LLCInventors: Nikica Maljkovic, Joe Paul Gibbons, Jr., John Francis Bosarge, Jr.

Patent number: 9335137Abstract: An ammunition cartridge casing having a geometry designed to allow for the use of polymeric materials in forming the walls of the cartridge casing of an ammunition article, and methods of reusing such cartridges are provided. More specifically, the ammunition cartridge has a specified ratio between the wall-thicknesses of select portions of an ammunition article's cartridge casing such that polymeric materials may be used in the construction of the ammunition article cartridge casings.Type: GrantFiled: October 6, 2015Date of Patent: May 10, 2016Assignee: MAC, LLCInventors: Nikica Maljkovic, John Francis Bosarge, Jr., Joe Paul Gibbons, Jr.

Publication number: 20020023046Abstract: A Business-to-Business Web-based system is disclosed that automates the process of bidding, negotiating, reporting and purchasing of goods or services from vendors. A list of vendors and associated vendor parameters is stored in a database accessible to a computer processor. A user interface associated with the processor is provided to enable a user to specify procurement requirements. Rules are applied by the processor to select at least one potential vendor based on the vendor parameters and procurement requirements. The selected vendor(s) are contacted over a global communication network and invited to submit a bid. The bids are submitted back over the network and the system analyzes them to recommend a vendor to the user. Quality data is provided by the user upon completion of the job, and used in subsequent vendor selection sessions.Type: ApplicationFiled: May 14, 2001Publication date: February 21, 2002Applicant: Professor Mac, LLCInventors: Patrick Callahan, Michael Nydell
