CONT

Jet dyeing is a process that can be used for batch dyeing operations such as dyeing, bleaching, washing and rinsing. In this process, dyeing is accomplished in a closed tubular system, basically composed of an impeller pump and a shallow dye bath. The fabric to be dyed is loosely collapsed in a form of a rope, and tied into a loop. The impeller pump supplies a jet of dye solution, propelled by water and/or air, to force the fabric to move through the tube into the shallow bath. Turbulence created by the jet aids in dye penetration and prevents the fabric from touching the walls of the tube, thus minimizing mechanical impact on the fabric.

Subject field(s)
  • Atomic Physics
DEF

A molecular device capable of converting energy into movement and able to generate forces on the order of piconewtons.

CONT

The nanomotor has a positioning stroke up to some centimeters while operating with atomic resolution and thus builds a bridge over eight orders of magnitude. The nanomotor is a piezo driven linear motor consisting of a cylindrical housing and a slider with a free axial hole inside. It utilizes a piezo tube for fine positioning and a pulse wave produced by the same piezo tube for coarse movements. Every point of its stroke can be reached with a speed of up to 5 mm/s. In its free axial hole the nanomotor can transport a tip, a hose, an electrode, a hypodermic needle, a glass fiber or even a microgripper. The nanomotor is available in three different versions. The "small" nanomotor is half the size of a match stick. It can lift six times of its own mass. The dynamic force of this nanomotor is so high, that even imprints in diamond surfaces can be produced. Special versions of the nanomotor can operate in ultra high vacuum, in liquid helium, even under water or as non-magnetic drives.

DEF

The moving of the electron beam by means of a magnetic field produced by a coil around the neck of the cathode-ray tube.

CONT

Magnetic deflection of the electron beam can be used instead of electrostatic deflection. A magnetic deflecting field is established in the tube just past the electron gun to react with the magnetic field associated with the electron-beam current, producing a force that deflects the electrons at right angles to both the beam-current axis and the deflection field.

OBS

Linear motion is produced by a sawtooth current through the coil.

Subject field(s)
  • Biological Sciences
DEF

Chromatography in which the adsorptive force is provided by molecules adhering to the surface of a solid packed in a column, spread as a thin film on a glass or plastic sheet, or as a coating inside a tube; the various components move through the stationary phase at different velocities, according to their degree of attraction to it, and are deposited at specific sites on the adsorbent.

CONT

Adsorption chromatography offers a powerful enzyme recovery technique as the relative specificity of interaction of the matrix used enables concentration and partial purification to be effected simultaneously. A number of examples exist where this method has been used very successfully in the initial recovery of extracellular enzymes on a large scale. However, most of those examples involve high cost enzymes, that is those required for research or analytical purposes.

Subject field(s)
  • Oil Drilling
DEF

Condition for working coiled tubing through a pressurized stripper, where wellbore pressure applied against the cross-sectional area of the tube creates an upward acting force greater than the weight of the tubing in the wellbore.

CONT

Snubbing usually requires an array of wireline blocks and wire rope that forces the pipe or tools into the well through a stripper head or blowout preventer until the weight of the string is sufficient to overcome the lifting effect of the well pressure on the pipe in the stripper.

OBS

snubbing: A term used to describe the process of removing or installing pipe into a pressurized well bore, using specialized equipment including blowout preventers in a special arrangement.

OBS

In this condition, mechanical assistance is required to apply thrust to the tubing while injecting or to maintain control of the tubing when extracting. This condition is commonly called "light pipe operations."

  • Weather Stations and Meteorological Instruments and Equipment
DEF

A type of pressure-tube anemometer, named after the inventor, in which the pressure head is located on the windward end of the wind vane so that it is kept facing into the wind.

CONT

The Dines Pressure Tube Anemometer is universally recognised as the most reliable and accurate instrument of its kind and has been adopted as standard by the British Meteorological Office and by meteorological stations world-wide. Dines Pressure Tube Anemometer consists essentially of a Head Assembly, a Velocity Recorder and a Direction Recorder, the IM100 records wind speed and wind direction simultaneously on a single chart. An important feature of the Dines, is that it records not only average wind velocity over a given time, but also variations in wind force, with the strength and frequency of gusts, providing valuable data on the internal structure of the wind.

CONT

The suction head is mounted concentrically with the shaft, near the bearing that supports the vane, and develops a suction that is independent of wind direction. The pressure difference between the suction head and the pressure head is proportional to the square root of the wind speed and is measured by a specially designed float manometer with a linear wind scale.

CONT

The Dines anemometer was first described by William Henry Dines in 1892 and had all the essentials of the final form of the pressure-tube anemometer. With various modifications, the Dines anemometer remained a useful wind measuring device into the 1960s.

Subject field(s)
  • Rheology
CONT

Another important type of non-Newtonian fluid is a viscoplastic or "yield stress" fluid. This is a fluid which will not flow when only a small shear stress is applied. The shear stress must exceed a critical value known as the yield stress... for the fluid to flow. For example, when you open a tube of toothpaste, it would be good if the paste does not flow at the slightest amount of shear stress. We need to apply an adequate force before the toothpaste will start flowing. So, viscoplastic fluids behave like solids when the applied shear stress is less than the yield stress. Once it exceeds the yield stress, the viscoplastic fluid will flow just like a fluid. Bingham plastics are a special class of viscoplastic fluids that exhibit a linear behavior of shear stress against shear rate.... Examples of viscoplastic fluids are drilling mud, nuclear fuel slurries, mayonnaise, toothpaste, and blood.

Key term(s)
  • yield-stress fluid

CONT

Les fluides à seuil sont des matériaux extrêmement courants dans l'industrie, en particulier pétrolière et agro-alimentaire. On peut citer comme exemples le yaourt, la mayonnaise, le dentifrice, la boue, etc. Pour faire couler ces matériaux, il est nécessaire d'appliquer une contrainte (force par unité de surface) supérieure à une valeur critique afin de casser leur structure interne.

Mercury flotation. The directive force of any gyrocompass is small when nearly on the meridian. It is therefore necessary to suspend it in as nearly a frictionless support as possible. This is accomplished by supporting the sensitive element on a hollow steel sphere which floats in a concentric tank of mercury... The sphere should clear the bottom of the tank by 3/16 in. For convenience in checking this position, a line has been placed on the contact support tube. This line is level with the topmost surface of the sensitive element when the flotation is correct.

DEF

A liquid filling technique which uses gravity in a vacuum atmosphere.

CONT

Pressure gravity. This method fills to a level. It is almost universally restricted to filling carbonated beverages. The flow principle is gravity as the force causing flow into the container. Like the gravity vacuum method, which fills by gravity in a vacuum atmosphere, this method fills by gravity in a pressure atmosphere. Product under pressure is held in an integral overhead supply tank on the rotary. Filling valves are mounted in the tank and are opened against spring pressure by the container being lifted to the valve. When the container is sealed to the valve, a mechanical latch opens a charging valve at the top of the valve vent tube which is above the product level in the supply tank.... Fill level is determined when the rising liquid covers a part in the vent tube through which the air in the container is exhausted as product flows in.
