| Among other things, a digitally controlled actuator has a connector for coupling to a drive mechanism of an existing hand-driven cartridge reloader, to actuate a series of processing cycles of the reloader in which supplies of components are subjected to successive mechanical processing steps to produce reloaded cartridges ready for use. There are sensors associated with the actuator and the reloader to (a) acquire digital information that is indicative of a state of progress of each of the processing cycles and of conditions of the reloader related to the production of the reloaded cartridges, and (b) deliver the digital information to a digital controller for controlling the processing cycles of the reloader. The digital controller is connected to receive the digital information from the sensors and to control automatic operation of the reloader in successive processing cycles to produce reloaded cartridges without requiring human intervention. | ||||||
| 64 | Automatic Apparatus for High Speed Precision Portioning of Granules By Weight | US14464405 | 2014-08-20 | US20150246769A1 | 2015-09-03 | Daniel David Pearlson |

| Secondary crystalline high explosives are disclosed which are suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms (MEMS), used as safe and arm (S&A) devices. The explosives are prepared by adding the such a high explosive to an aqueous first volatile mobile phase, adding such a high explosive to a non-aqueous second volatile mobile phase, mixing the first and second volatile mobile phases and then loading the combined phases into the MEMS device and allowing the aqueous and non-aqueous solvents to evaporate depositing the high explosive. Enhanced adhesion between the deposited high explosive and enhanced rheological properties can be obtained by adding a polymeric binder to both mobile phases. | ||||||

| 73 | Cast booster using novel explosive core | US11344662 | 2006-02-01 | US08127682B1 | 2012-03-06 | John Sonday; Rick Spriggle; Dan Wasson |
| An improved cast booster design and method of assembly is provided for the detonation of blasting agents. The booster design utilizes a pre-formed core that simplifies assembly of the booster and increases the reliability of detonation transfer from a blasting cap. The pre-formed core has a cup shaped aperture provides improved coupling with the initiation source. The pre-formed core is made using a relatively insensitive explosive composition that can be manufactured using high speed pressing methods. The explosive composition allows for the attainment of a well defined shape with a predictable density. The pre-formed core shape mates with the casting mold in a way that ensures the location of the core within the booster thereby improving reliability and reducing labor associated with the booster manufacturing operation. | ||||||

| The invention relates to a cartridge having a propellant charge casing at least partially filled with a propellant charge powder, and a projectile part connected on a front of the propellant charge casing, wherein the propellant charge casing comprises a casing cover, a casing sheath and a casing base, and the casing sheath is connected to the projectile part via the casing cover and to the casing base via a spring steel sheet. In order to achieve different amounts of propellant charge powder filled into the same propellant charge casing without igniting the propellant charge at undesirable blast waves, a sack-shaped container that is completely filled with the respective amount of propellant charge powder is disposed inside the propellant charge casing so that the container, and thus also the propellant charge powder, extends in the direction of the central longitudinal axis of the cartridge. | ||||||
| 75 | Method of charging a container with an energetic material | US11547620 | 2005-04-08 | US20070184219A1 | 2007-08-09 | Richard Johnson |
| The present invention provides a method of charging at least one container, such as a tube, with an energetic material. The method comprises the step of reducing a pressure of a fluid in an interior portion of the or each container. The method also comprises the step of positioning the energetic material at a position that is exterior to the or each container and at which a pressure is higher than in the interior portion of the or each container in a manner such that a suction results which sucks the energetic material into the interior portion of the or each container and thereby charges the or each container with the energetic material. | ||||||

| High explosives suitable for filling very small volume loading holes in micro-electric initiators for micro-electro-mechanical mechanisms, used as safe and arm devices, are prepared from slurries of crystalline energetic materials and applied using various methods. These methods include swipe loading, pressure loading and syringe loading. A volatile mobile phase may be added to the slurry so as to partially dissolve the energetic material so that, upon evaporation of the mobile phase, the energetic material precipitates and adheres to the loading hole. | ||||||
| 77 | Ammunition reloading apparatus with feed mechanism | US10214977 | 2002-08-07 | US06772668B2 | 2004-08-10 | Steven Robert Shields |
| Ammunition reloading apparatus includes a shell case support for holding a shell case, a container spaced above the support for holding shell loading material to be placed in a shell case during reloading, and an elongate charge bar underlying the container having a charge opening therein. The bar is mounted for movement between a first position in which the opening underlies the container to receive a charge of material and a second position where the material may be released to an underlying shell case. Control mechanism is operable to sense the presence or absence of the shell case on the support when the charge bar is in its second position. The control mechanism prohibits release of material from the charge opening when a shell case is absent and permits release of material to be dispensed to the shell case when a shell case is present. | ||||||

| 79 | Disposable explosive foam dispenser | US338039 | 1999-06-22 | US6112633A | 2000-09-05 | Joseph Trocino |
| A lightweight aerosol dispenser enclosing a first component of an explosive nature is filled at a factory. A second component is supplied in a smaller container, separate from the dispenser, containing a predetermined amount of propellant. By providing separate containers for each of the explosive and propellant components, both components retain their classification as a flammable substance for transportation and storage purposes. However, in the field, the propellant is injected into the solution container immediately before use. Only after the two substance components have been mixed can an explosive composition be produced. If, for any reason, the explosive composition comprising a foam is not used, it can be washed away with water or will dissipate itself within a few hours. | ||||||
| 80 | Methods of priming explosive devices | US245972 | 1981-03-20 | US4640724A | 1987-02-03 | George B. Carter; Alan P. Manby |
| The invention provides a method of priming a blank or bulleted rimfire cartridge comprising the steps of (a) dosing into the rimfire case a quantity of a substantially dry, powdery, relatively insensitive premix comprising, in predetermined proportions, at least two materials that will, in the presence of a liquid reaction medium, react together forming a primary explosive compound, (b) compacting the premix so as substantially to fill the rim of the case therewith, (c) dosing a quantity of the liquid reaction medium into the case so as to cause said materials to react together forming the primary explosive compound and (d) drying the primer. By compacting the premix into the rim before the addition of the liquid reaction medium, the conventional spinning step may be dispensed with, thereby making the priming process safer and more economic. | ||||||
