  • Publication number: 20240120809
    Abstract: A fluid pump includes a motor disposed within an outer housing. The motor includes a stator and a rotor in electromagnetic communication with the stator. Windings are disposed on the stator that receive an electric current for defining the electromagnetic communication. A pump element is attached to the rotor via a drive shaft. The pump element operates with the rotor to deliver a fluid through a hydraulic fluid path. A plurality of sensors measure information related to at least one of the stator, the windings, the rotor, the pump element, the fluid and the hydraulic fluid path. A controller is in communication with the windings for delivering the electric current to the windings. The controller is also in communication with the plurality of sensors for measuring and recording the information and communicating this information to one of an external memory and an external controller.

  • Publication number: 20160101443
    Abstract: The separator/dryer includes a housing, removable collection trays, a separator assembly, a rinse assembly, and a heater/blower. The separator assembly separates the ammunition casings from the clean media and the rinse waste and includes a rotating separator basket disposed within the housing on a motor driven shaft. The rinse assembly provides a water shower to rinse any cleaning residue, carbon particulate and dust from the ammunition casings and the cleaning media. The heater/blower circulates a stream of hot air into the housing interior to dry ammunition casings and the cleaning media. The removable collection trays are vessels for collecting both the rinsed and dried ammunition casings and the rinsed and dried clean media.
