A hair dryer (the handheld type also referred to as a blow dryer) is an electromechanical device that blows ambient air in hot or warm settings for styling or drying hair. [ 1 ] [ 2 ] Hair dryers enable better control over the shape and style of hair, by accelerating and controlling the formation of temporary hydrogen bonds within each strand.
The barber would select a closeness setting for this. Some electric clippers such as the Wahl clipper, or the Andis clipper had a lever that could be moved back and forth to change the closeness from "000"which left the hair stubble length, or "1" which left the hair about one eighth of an inch.
Air jet loom. An air-jet loom is a shuttleless loom that uses a jet of air to propel the weft yarn through the warp shed. [1] It is one of two types of fluid-jet looms, the other being a water-jet loom, which was developed previously. [1] Fluid-jet looms can operate at a faster speed than predecessor looms such as rapier looms, but they are not ...
An electric trimmer. Electric hair clippers work in a similar way as manual ones, but are driven by an electric motor which makes the blades oscillate from side to side. [6] They have gradually displaced manual hair clippers in many countries. Three different motor types are used in clipper production: magnetic, rotary and pivot.

Dust collection is an online process for collecting any process-generated dust from the source point on a continuous basis. Dust collectors may be of single unit construction, or a collection of devices used to separate particulate matter from the process air. They are often used as an air pollution control device to maintain or improve air ...
Usually, an auxiliary power unit is used to start the engines. It has a starter motor which has a high torque transmitted to the compressor unit. When the optimum speed is reached, i.e. the flow of gas through the turbine is sufficient, the turbines take over. There are a number of different starting methods such as electric, hydraulic ...
The jet-air dryer, which blows air out of the unit at claimed speeds of 180 m/s (650 km/h; 400 mph), was capable of blowing micro-organisms from the hands and the unit and potentially contaminating other users and the environment up to 2 metres away. Use of a warm-air hand dryer spread micro-organisms up to 0.25 metres from the dryer.
