  • Patent number: 10837744
    Abstract: A shot shell includes a cartridge (also referred herein as a ‘hull’), a primer, gunpowder, a tungsten propulsion system wadding, shot pellets having a first size, and shot pellets having a second size that is larger than the first size, and a 5-8 star crimp on an upper portion of the plastic cartridge. It has been found that there are advantages to loading smaller shot (preferably 3 shot or 4 shot) first, and then loading larger shot (preferably 1 shot or 2 shot) so that the larger shot leaves the cartridge first when the shot shell is fired. In a preferred embodiment, the cartridge contains 40% to 60% large shot, and the remainder of shot pellets in the cartridge is smaller shot. In an alternate embodiment, the large shot may be loaded first, and the smaller shot loaded last, so that the smaller shot leaves the shot shell first.

  • Patent number: 8061955
    Abstract: A container carrier having a support frame pivotally connected at its bottom end to a truck chassis and a carrying frame pivotally connected at its top to the top of the support frame. The carrying frame has support arms for holding a container. The support frame is generally upright with the carrying frame folded adjacent the support frame when the carrier is in a container carrying position on the truck chassis, the center of gravity of a carried container located forwardly of the rear wheels of the truck. The support frame extends rearwardly with the carrying frame unfolded when the carrier is in a container pick-up position. In the pick-up position, the support arms on the carrying frame are located past the rear end of the truck chassis and extend rearwardly therefrom to engage a container on the ground. Moving means move the support and carrying frames between the carrying position and the pick-up position.

  • Publication number: 20060278003
    Abstract: Pressure measurement may be achieved by using a pressure-conveyance media that responds to externally applied pressure to convey pressure to a pressure sensor. With the conveyance of pressure, the pressure measurement may be accomplished by determining a pressure of the pressure-conveyance media, determining a temperature of the pressure-conveyance media, and determining pressure externally exerted on the pressure-conveyance media based one the pressure of the pressure-conveyance media and the temperature of the pressure-conveyance media.
