Abstract: The present invention relates to an article which provides hygienic protection to an individual when using public toilets. The article in question is foldable and can be conveniently carried by the individual. In addition, the article in question is applied to the individual and not to the toilet seat.

Abstract: A method for inspection of tubular goods includes using ultrasonic detection means to obtain wall thickness measurement of discrete sections of a tubular good and recording each measurement in association with both the longitudinal and circumferential position at which each measurement was obtained. Accordingly each measurement of wall thickness represents a small portion of the wall thickness of said tubular in three dimensional space. A plurality of said measurements may thereby be displayed by computer means in virtual three dimensional format. Differing wall thickness readings made be represented by different shading or color display, so that anomalies of interest may be readily detected. Alternatively the recorded information may be readily processed by computer means to calculate the effect of stressors on the wall of said tubular good.
