Patent EP-0217783-A2 (EP)
Inventor: GANGLBAUER OTTO
IPC: G01N29/00
Filed: 1986-09-15
Abstract: In a method of flaw classification on and in welds of planar or arcuate plate-shaped workpieces of uniform thickness by means of ultrasonics, the expected flaw areas of the workpiece are pre-examined manually and are then examined systematically using the ultrasound echo image method in separate cross-sectional planes. A B-scan is thus generated, and changing the position of the transducer on the workpiece and/or the transmitting direction enables defects to be located by calculating the delay time of ultrasound waves in the go-and-return directions within the workpiece under consideration of possible reflections at the rear side (8) of the workpiece. For defining the test conditions, part-specific parameters are considered, such as weld type and weld shape (e.g., double-V-weld and bell seam), weld geometry (e.g. seam angle), and part characteristics (e.g. wall thickness), whereupon with the aid of a computer into which the parameters have been inputted, a graphic representation corresponding to a B-scan is generated. In the graphic representation at least one area, in which the density of obtained reflection points per unit of area exceeds a predetermined value, is surrounded by a closed curve of second order, generally an ellipse, and the angular direction of a privileged axis, particularly the major axis of the ellipse, in relation to a reference system, the axis ratio and/or the center location are calculated. Reflection points, located opposite from each other, of a defect are detected, and the ratio between length and thickness of the defect or the orientation tendency, respectively, is calculated, whereupon at least by logically linking orientation tendency and path difference a discrimination between volumetric-type defects, planar defects and a combination of such defects is brought about.

Abstract: A holder (18) for receiving and frictionally securing yarn package (12) wound onto tubes of various inner diameters is disclosed. The holder comprises a base support which includes an arm (20) adapted to be attached to the textile machine. Extending at a right angle from the base arm is a cantilever contact arm (24) which is rigidly connected to the base. The contact arm has a contoured support arm (28) pivotally connected to its free end and extending alongside the contact arm to a point near the base support. A spring (34) is interposed between the contact arm (24) and the contoured support arm (28) and urges them apart, and against the inner walls of a yarn tube (13) placed about the contact arm and the contoured support arm. 
     A second embodiment has two contoured support arms, one of which is pivotally connected to the contact arm at a point intermediate a free end portion of said contact arm and the base support. A resilient second contoured support arm is affixed to the end of the contact arm and has a portion which extends generally transverse over the longitudinal axis of the contact arm. One end of the second contoured support arm extends beyond the tube contact surface of the contact arm for a slight distance not to exceed three-sixteenths of an inch and the other end of the second contoured arm extends towards said base support at an acute angle to the   longitudinal axis of the contact arm. The second contoured support arm cooperates with the first in firmly anchoring intermediate yarn tube on the support while the second contoured arm is adapted to handle yarn tubes of very small diameters.
