Single mode Only the fundamental zeroorder mode is transmitted in a singlemode fiber. The light beam travels straight through the fiber with no reflections from the corecladding sidewalls at all. Singlemode fiber is characterized by the wavelength cutoff value, which is dependent on core diameter, NA, and wavelength of operation.
roller cone bit. 1. n. [Drilling] A tool designed to crush rock efficiently while incurring a minimal amount of wear on the cutting surfaces. Invented by Howard Hughes, the rollercone bit has conical cutters or cones that have spiked teeth around them. As the drillstring is rotated, the bit cones roll along the bottom of the hole in a circle.

Jun 20, 2020 · The determination of the ULS plays an important role especially when the ship results damaged and the salvage operation is needed. In fact, grounding or collision can lead to a reduction in the effectiveness of the structural elements and consequently to the reduction of ultimate strength. Figure 4 Damage due to grounding [5]
The accompanying graph illustrates how cone height, represented by h, and plate thickness, represented by t, affect a washer's load carrying capacity. Graph credit: Century Spring . Spring Washer Material . Spring washer operation is dependent on the elastic deformation of it's material, which should have good tensile strength and elastic limits.
1. The increased mud weight reduces drilling rate with the rollercone bits. 2. The gas in the mud reduces pump volume efficiency and the fluid flow rate down the drill pipe. 3. The risk of losing circulation and/or stuck pipe due to greater hydrostatic pressure is increased if the formation is pressure sensitive.
