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

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.
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.
To ensure complete filling of the gear pump with common rubber compounds, the single screw extruder only needs to build up 40 to 50 bar pressure at the inlet of the pump.
Figure 2 shows a comparison of the output decrease between a single screw extruder and gear pump during pressure increase.
With twin screw extruders in our lines we have the broadest array of plastics processing machinery and technology in the world, and we are moving aggressively to increase market share with a 'one-stop-shopping' concept that offers our customers the widest choice of processing alternatives for the broadest range of materials.
The acquisition was finalized in Germany where the advanced twin screw extruders will be manufactured by the newly formed Farrel-Rockstedt GmbH.
Extrusion is used for about half of all plastics product manufacture, mostly using single screw extruders.
The TEM-41SS and TEM-26SS extrusion systems include the twin screw extruders coupled with AccuRate Mechatron gravimetric feeders, pelletizing systems and other auxiliary equipment.
