CARTRIDGE RELOADING IMPROVEMENTS
20170370685 · 2017-12-28 ·

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.

Integrated polymer and metal case ammunition manufacturing system and method

A fully automated, integrated, end-to-end synchronized and compact manufacturing system produces polymer or metal case ammunition. Manufacturing stations support case assembly, sealing (gluing/welding), final product inspection, cartridge packaging or binning, and loading. Station modularity facilitates rapid changeover to accommodate ammunition of differing calibers. Sensors and apparatus may be provided to place a manufacturing cell in a wait state until all components or materials are received in a preferred orientation for proper assembly. The system may join and use multipart cases, each including a lower portion with a head end attached thereto and at least one upper portion having a necked-down transition to the open top end. Elevator feeders, vibratory bowl feeders, and robotic pick-and-place feeders may be used to deliver components for assembly.

Systems, devices, and methods including a bullet; a retroreflector array adhered to a base of the bullet, the retroreflector array having prism facets with a periodicity between 0.2 mm-2.0 mm; and a cover disposed over the retroreflector array and hermetically sealed at the base of the bullet; where the cover is disposed over the retroreflector array in a first position prior to firing, and where the cover is released from the base of the bullet in a second position after firing.

Combination oven with peak power control

A commercial oven, such as a combination oven providing steam and convection heating, may provide for two different peak power modes and for steam cooking. A temperature sensor sampling temperature from a region of the oven may be used to detect a complete filling of the oven with steam. The temperature of the temperature sensor is compared against different temperature thresholds depending on the selected peak power so that temperature may be used to discriminate steam filling for different peak power levels.
