  • System and method for delivering fuel
    Patent number: 11498827
    Abstract: A system for delivering fuel to an equipment fuel tank. The system includes a remote fuel storage tank and a valve assembly coupleable to the equipment fuel tank. The system includes a fuel supply line extending between the remote fuel storage tank and the valve assembly and a pneumatic valve disposed in the fuel supply line. The pneumatic valve can prevent flow of fuel into the fuel supply line or can enable flow of fuel into the fuel supply line. The valve assembly includes pressure tubes to detect changes in fuel level inside the equipment fuel tank. A switch actuates the pneumatic valve to prevent the flow of fluid in response to an overfilled position; and actuates the pneumatic valve to enable the flow of fluid in response to an underfilled position.
    Type: Grant

  • Quick loading magazine
    Patent number: 9103614
    Abstract: The present disclosure provides a quick loading magazine that is easier and less cumbersome than previous ammunition magazines. A quick loading magazine is disclosed. An upper portion of the quick loading magazine is coupled to a lower portion, with the upper and lower portions defining a slider channel and a bullet channel. A feeder lip is coupled to the upper portion. A slider is configured to travel along the slider channel between a first position and a second position. A follower is coupled to the slider by a biasing member, and the follower is also configured to travel within the bullet channel.
