Abstract: An apparatus and method for sorting ammunition casings and adapted to be mounted on a vibrating base. The apparatus includes an input hopper adapted to receive ammunition casings and a sorting track in communication with the input hopper where the sorting tracks has a graduated opening the bottom of the track such that the diameter of the graduated opening increases as the opening extends away from the hopper. The apparatus further includes sorting compartments arranged under the sorting track. Vibration moves the casings from the input hopper to the sorting track, and as the casings move along the sorting track, smaller diameter casings fall through a first opening portion into a first sorting compartment, and larger diameter casings move along the sorting track past the first opening portion and subsequently fall though a second opening portion into a second sorting compartment thereby separating the ammunition into different calibers.

Abstract: A circuit for interfacing switches to a component which allows the positions of the switches to be determined by the component. The component includes an input port and an output port. A switch network which is a parallel combination of two or more series combinations of a resistor and a switch is connected between the input and output port. A capacitor is connected between the input port and ground. The component determines switch positions by outputting a voltage on the output port and determining the time for the capacitor to charge to a predetermined value. Since each series combination has a unique resistance, the position of the switches therein can be determined in accordance with the capacitor charging time.
