The indicator includes a dial having a rotatable needle for indicating the deviation of the tube wall thickness from the thickness of the selected standard item.Īn apparatus for measuring the thickness of a tube's wall for the tube's entire length and circumference by determining the deviation of the tube wall thickness from the known thickness of a selected standard item. The contact ball then contacts the tube when the tube is disposed about the spherical element. The indicator includes a contact ball for first contacting the selected standard item and holding it against the spherical element. An indicator is connected to the positioning element and is movable to a location proximate the spherical element. A positioning element is connected to and movable relative to the second support member. ![]() A second support member is connected to the base and spaced apart from the first support member. The first end is connected to the base and the second end is connected to a spherical element. The apparatus comprises a base and a first support member having first and second ends. ![]() Tube wall thickness measurement apparatusĪn apparatus for measuring the thickness of a tube's wall for the tube's entire length and radius by determining the deviation of the tube wall thickness from the known thickness of a selected standard item. The plurality of grooves may be positioned in a radially outer region of the airfoil proximate to the tip. The material forming an outer surface of the outer wall may be removed to be flush with an innermost point in each groove, thereby reducing the wall thickness and increasing efficiency. The grooves may have a depth that represents a desired outer surface and wall thickness of the outer wall. The airfoil may include an outer wall having a plurality of grooves in the outer surface of the outer wall. Marra, John J James, Allister W Merrill, Gary BĪ turbine airfoil usable in a turbine engine and including a depth indicator for determining outer wall blade thickness. Turbine airfoil with outer wall thickness indicators Relative image error and correlation coefficients are used for image evaluation using both simulation and experimental data. Linear back- projection and Landweber iteration algorithms are used for image reconstruction. The sensitivity distributions and potential distributions are compared for different wall thicknesses. Three flow patterns are simulated for wall thicknesses of 2.5 mm to 15 mm on eight-electrode ECT sensors. This paper will discuss the effect of the wall thickness of ECT sensors on image quality. In the design of electrical capacitance tomography (ECT) sensors, the internal wall thickness can vary with specific applications, and it is a key factor that influences the sensitivity distribution and image quality. Liang, Shiguo Ye, Jiamin Wang, Haigang Wu, Meng Yang, Wuqiang Influence of the internal wall thickness of electrical capacitance tomography sensors on image quality Thereafter, an optical comparator is employed to project a magnified image of the ball on a screen and the wall thickness at the selected point is calculated by using a ball surface measurement taken with the comparator in conjunction with a previously determined base line measurement. To determine the wall thickness of the article at a selected point, a magnetically responsive ball is positioned within the tubular article over said point and retained therein by means of a magnetic field produced by the magnet. The tubular article and the housing are releasably secured to the supporting surface and a support member of an optical comparator, respectively. We would like to brew one as well for flowstate chocolate, starting here in Cebu.Wall thickness measuring method and apparatusĪn apparatus for measuring the wall thickness of a nonmagnetic article having a housing supporting a magnet and a contiguous supporting surface. ![]() Craft chocolate makers focus instead on bringing out the best bars from each batch of cacao beans.Ĭraft chocolate is a revolution in the world of solid state chocolate. The craft chocolate movement is growing worldwide, rebelling against the uniformity and the flattening of flavor that mass production brings. Whole also means the cacao is not alkalinized, a process which tames the wildness of cacao flavor, making it more predictable but also removes the delicious outliers among its notes. Whole means that its cacao butter, which gives chocolate its silky feel, is fully intact. We would have to use whole cacao liquor instead of cocoa powder. If we treat our sipping chocolate the way we treat our coffee, how would it look like? In the past years, Cebu has had a flourishing of craft coffee-passionate baristas brewing coffee for us with careful precision and using world class beans.
