Study on the Holding Characterestics of a Magnetic Gripper

R. Wadhwa[1], G. Monkman[2], and T. Lien[1]
[1]NTNU Valgrinda, Inst. for produksjons- og kvalitetstek., Trondheim, Norway
[2]FH Regensburg, Regensburg, Germany

Magnetic grippers are commonly used for workholding in handling and assembly of ferrous metalcasted parts. The workholding force produced by the magnetic gripper is strongly influenced by the texture and form of the workpiece in contact with its surface. This work explores the ... Per saperne di più

Using the Superposition Principle and Edge Current Model to Compute Impedance of the Coil in a Logging Tool

T. Zhao, G. Minerbo, J. Hunka, and G. Hazen
Schlumberger
Sugar Land, TX

Coil antenna is the simplest form in well-logging tools for resistivity measurement of the formation. This paper introduces how to accurately compute the impedance of the coil with very thin wires at high frequency, and with the complex borehole structure, e.g., metal housing and ...

Modeling of Susceptor Assisted Microwave Heating in Domestic Ovens

K. Pitchai[1], S. Birla[2], J. Diamond Raj[3], J. Subbiah[2], and D. Jones[2]
[1]Dept. of Food Science and Technology, University of Nebraska, Lincoln, NE
[2]Dept. of Biological Systems Engineering, University of Nebraska, Lincoln, NE
[3]Indian Institute of Crop Processing Technology, Thanjavur, Tamil Nadu, India

Susceptors are very thin metallic microwave absorbing films used in microwaveable food packaging. They tend to heat up very rapidly during microwave heating and this effect helps to overcome two major issues faced in domestic microwave ovens; 1) Non-uniform heating and 2) lack of ...
