BARREL SHELL [7 records]

Record 1 2020-10-22

English

Subject field(s)
  • Antique and Obsolete Weapons
CONT

A rifled muzzle loader(RML) is a type of large artillery piece invented in the mid-19th century. In contrast to smooth bore cannon which preceded it, the rifling of the gun barrel allowed much greater accuracy and penetration as the spin induced to the shell gave it directional stability.

CONT

A long recoil action uses the force of recoil to achieve the seven steps of operation. It requires the barrel and bolt(locked together) to travel rearward for a distance somewhat greater than the full length of the fired cartridge before coming to a stop, so that the fired shell may be extracted and ejected.

  • Boring and Drilling (Mines)
  • Oil Drilling
DEF

A core-fishing device consisting of a tube fitted internally at its lower end with flat, flexible spring fingers that permit core to enter the tube but close when the device is hoisted from the borehole, preventing its escape.

CONT

Loose core accidentally left in a drill hole, may often be recovered with a core picker. This tool screws into the end of [a] core barrel outer tube in place of assembly of bit and reamer shell. In use, the core picker and outer core barrel assembly is lowered or pushed to the bottom of the drill hole, sliding over any loose core. On removing the assembly from the hole, the loose core is held in the core barrel by the flexible internal spring provided in the core picker...

  • Equipment (Oil and Natural Gas Extraction)
  • Boring and Drilling (Mines)

DEF

A tool employed in drilling and used for smoothing the wall of a well, enlarging the hole to the desired size, stabilizing the bit, straightening the wellbore where kinks or doglegs are encountered, and drilling directionally.

CONT

The outside surface of the reaming shell is provided with inset diamonds or other cutting media set to a diameter to cut a specific clearance for the core barrel.

CONT

Reaming shells maintain the desired diameter of the [bore] hole. These make it unnecessary to ream with new bits to the bottom, reduce wear on the core barrel, and prevent sticking of bits due to loss of gauge.

CONT

Internally, the reservoir is equipped with a piston and diaphragm assembly which utilizes system pressure from the small pressure-line port to maintain a pressure head on the supply fluid.... As fluid enters the reservoir, the diaphragm is forced upward inside the reservoir shell, thus carrying the diaphragm guide and barrel upward.... as the diaphragm guide raises and lowers, the linkage will be moved, and this will provide the signal which is sent electrically to the fluid-quantity indicator in the cabin.
