extrusion

 [ek-stroo´zhun]
1. a pushing out.
2. in dentistry, the condition of a tooth pushed too far forward from the line of occlusion as a result of injury or of lack of opposing occlusal force.

ex·tru·sion

(eks-trū'zhŭn),
1. A thrusting or forcing out of a normal position.
2. The overeruption or migration of a tooth beyond its normal occlusal position.

extrusion

[ek·stro̅o̅′zhən]
Etymology: L, extrudere, to push out
1 thrusting or pushing out; expulsion by force.
2 the overeruption or movement of a tooth beyond its normal occlusal plane in the absence of opposing occlusal force.
3 an orthodontic technique for the elongation or elevation of a tooth. Compare intrusion.

herniated disk

Herniated intervertebral disk, herniated nucleus pulposus, prolapsed intervertebral disk, slipped disk Neurology The herniation of an intervertebral disk, most commonly, lumbar; the term herniation in this context describes a spectrum of disk defects
Herniation disk types, used for MRI exams
Bulge–circumferential symmetric extension of the disk beyond interspace
Protrusion–focal or asymmetric extension of the disk beyond interspace
Extrusion–more extreme extension of the disk beyond interspace Note: Bulges and protrusions on MRI examination are common findings in normal subjects, and appear to be coincidental findings–NEJM 1994; 331:69oa

n the movement of teeth beyond the natural occlusal plane that may be accompanied by a similar movement of investing tissues. See also eruption, continuous.

extrusion

a pushing out; e.g. an orthodontic procedure which makes a tooth emerge further from its alveolus.

To ensure complete filling of the gear pump, the single screw extruder normally only needs to build 40 to 50 bar pressure at the inlet of the pump.
Rising pressure causes a significant drop of the specific output per screw revolution for the single screw extruder.
When considering the processing advantages of both a single screw extruder and a gear pump, there are compelling arguments for combining the two units in an engineered modular design in order to achieve the best possible straining performance; high output, lower compound temperatures, all coupled with higher mesh screen packs.
This creates opportunities for new textures and density management control for direct expanded products (ranging from snack food to fish feed) and allows more efficient use of the high screw speed capability of highly performing twin screw extruders.
The use of a single screw extruder as a proven unit for feeding hot or cold rubber compounds ensures a continuous rubber flow through the inlet of the gear pump.
