| 77 | Automatic Apparatus for High Speed Precision Portioning of Granules By Weight | US14464405 | 2014-08-20 | US20150246769A1 | 2015-09-03 | Daniel David Pearlson |
| An automated granule portioning system includes at least one volumetric measuring chamber capable of adjusting the volume of the chamber automatically to a programmed target volume and arranged to receive a first portion of granules into the chamber to fill the target volume. A transport system automatically delivers the target volume of granules from the chamber to a weighing device. A granule metering device dispenses granules and, depending on a signal from the weighing device that the first portion of granules is below a programmed target weight, dispenses granules to the first portion to increase the weight to achieve a second portion having the target weight. | ||||||
| 78 | 40 mm gun sleeve cartridge case for M320 grenade launcher ammunition | US13714759 | 2012-12-14 | US09010248B1 | 2015-04-21 | Leon Manole; Arthur Ricardo Pizza; Ernest Lee Logsdon; Gary Anthony Pacella; Anthony J. Sebasto |
| A non-spinning 40 mm ammunition round for firing in an M320 grenade launcher. The round includes a cylindrical shaped gun sleeve cartridge case, which covers the standard rifling inside the M320, and thus presents a smooth bore surface to the fired ammunition.
