milled material within the grinding chamber. The spiral jet mill contains two gas inlets: the injector gas and grinding gas inlets. The injector gas is used to propel the feed material into the grinding chamber of the mill. The grinding gas creates a circular motion of fluid in the grinding chamber which entrains the entering feed material.

A spin is fundamentally an aggravated stall. The only way to recover from a stall is to reduce the angle of attack, and that is done by moving the control column forward. In a spin, this can seem a very unnatural thing to do since the aircraft's nose is often pointed down. But it's the only way to get out of the situation.
Smithson completed the work in 1970, drawn to the otherworldliness of the lake's North Arm, with its salt crystal deposits, black basalt rocks, and rosy red water colored by microorganisms. The ...
The birds keep away. During flight, when the engine is running, birds see the spinning spiral as opposed to just a black hole, and hence they stay away from it. It is like an anti- signal because if there …

At low speeds, the air flows splits when it meets an object and, providing the object is reasonably aerodynamic, flows right around it, closely following its outline. But the faster the air flow and the less aerodynamic the object, the more the air flow breaks away and becomes turbulent. That's what we mean by form drag.

Abstract The formation of the Southern Hemisphere spiral jet is investigated using observations over a 40-yr period. It is found that between late March and early April, the upper-tropospheric westerly jet in the Southern Hemisphere undergoes a transition from an annular structure in midlatitudes to a spiral structure that extends from 20° to 55°S. …
The cutterhead or cutterblock is the rotating metal cilinder in which the blades (also called knives) are placed. Traditional jointers and planers have a set of straight blades, usually two or three. These blades are similar to the blades you find in hand planes, except much wider and shorter. The new spiral cutterheads have many small ...

Bars are perhaps one of the most important catalysts for changing a galaxy. They force a large amount of gas towards the galactic center, fueling new star formation, building central bulges of stars, and feeding massive black holes. "The formation of a bar may be the final important act in the evolution of a spiral galaxy," Sheth said.
