HELICAL CHAMBER [3 records]

Record 1 2012-09-12

English

Subject field(s)
  • Ballistics
  • Small Arms
CONT

Bullet traps can be grouped into three broad categories, deceleration, impact, and friction, though there is some blurring of the dividing line. Deceleration traps use a circular or helical chamber to allow the bullet to spin inside until it has shed sufficient velocity to drop through a recovery port in the bottom.

CONT

In a pneumatic plant the germination bed depth will often be greater than one meter. If left alone, the heat produced would accelerate growth and the roots would matt together forming a solid mass. This was the problem that Galland had in his first plan. To overcome this, the bed must have a perforated floor with a chamber below so that air can be blown through the bed. Hence the term pneumatic malting. This air must be humidified to stop the grain from drying out, but more water will be lost from the bed than in floor malting. Additionally, the grain bed must be turned using large helical screw turners.

A sprayer equipped with a cone nozzle.

CONT

Cone nozzle. Liquid is forced through a swirl plate, having one or more tangential or helical slots or holes, into a swirl chamber. An air core is formed as the liquid passes with a high rotational velocity from the swirl chamber through a circular orifice. The thin sheet of liquid emerging from the orifice forms a hollow cone as it moves away from the orifice, owing to the tangential and axial components of velocity. A solid cone pattern can be achieved by passing liquid centrally through the nozzle to fill the air core : this gives a narrower angle of spray and larger droplets.
