According to a first aspect of the present invention, there is provided a method of slowing down a moving projectile, the projectile moving within an electromagnetic railgun, the method comprising: using an electromagnetic field generated by the railgun to slow down the projectile, wherein the projectile is a munitions projectile, and/or a carrier for catching the munitions projectile.

Missile balancing assemblies include two balancing rings configured for mounting on a missile, each balancing ring having a ballast. Each balancing ring is configured to be rotated and rotationally fixed, and may include materials having different densities at different locations. Each balancing ring may further include an angular graduation.

A rotary shock-testing machine including: a base; a first shaft rotatable relative to the base, the first shaft being driven to rotate; a first wheel rotatable with the first shaft; a second shaft rotatable relative to the base; a second wheel rotatable with a first portion of the second shaft; and a test disc for holding one or more specimens to be tested, the test disc being rotatable with a second portion of the second shaft; wherein the first and second wheels are aligned with each other such that the second wheel is driven by the first wheel when a material is introduced into a gap between a surface of the first wheel and a corresponding surface of the second wheel.

A method involves inscribing a unique ballistic information number (BIN) on a bullet in process of manufacture of a cartridge, the cartridge including a shell casing holding the bullet, recording the BIN in a network-connected database, recording, at point of sale, identity of a person who purchases the cartridges, associating the person who purchases the cartridges in the network-connected database with the BIN inscribed on the bullet and recorded in the network-connected database, and transacting an insurance policy insuring the person for liability for damages caused by use of the cartridges and associating the insurance policy with the identity of the person in the network-connected database and with the BIN.

A receptacle in the body of a missile includes a plurality of electrical contacts connected to one or more electrically powered devices within the missile and configured to connect to an electrical power source. The receptacle receives a removable and reusable battery pack including connectors contacting the plurality of electrical contacts when the battery pack is mounted within the receptacle and one or more non-chemical, squibless batteries, preferably comprised of high power density primary cell lithium metal oxide cells. An interface circuit coupled to the squibless batteries initiates, terminates, and re-initiates delivery of electrical power from the squibless batteries to the plurality of electrical contacts based on a control input. Transportation, storage, and use risks associated with squibs in chemical batteries are avoided. During development testing, battery power may be shut down and restarted without the battery first becoming fully depleted and replaced shortening overall testing time and reducing expense.

Structure of a facility for demining, investigating and testing of an explosive device which comprises several structural elements connected to each other for processing an explosive device. The elements comprise a chamber for demining, investigation and testing, and for the initial suppression of the potential explosion shock wave and primary collection of the explosive residues, a chamber for secondary suppression and secondary collection of the explosion shock wave, a chamber for final suppression of the shock wave including filtration and the final collection of the explosive residue and the shock wave spreading space. The chambers have openings in front, where shock wave deflectors have been placed and behind the openings have been placed barrier walls. In the chamber walls and the ceiling have been placed cameras, lights, lighting tunnels and ventilation equipment. Between the chambers are automatic opening and closing doors, and the building is covered with a composite cover.
