Abstract

109,074. Marks, E. C. R., (Zahm Manufacturing Co.). Aug. 25, 1916. Testing filtering-elements. - Hollow filtering- bodies are tested by the application of gas pressure to the interior of the moistened bodies; the formation of gas bubbles on the exterior indicates exces. sive porosity. As shown, a tube 2 of infusorial earth is immersed in water in a glass vessel and is connected to an air or gas supply pipe 3 with a cock 4,
