Abstract

537,588. Testing efficiency of hollow-ware. HOFFMAN, W., and STYLO SOC. ANON. April 12, 1940, No. 6693. [Class 106 (ii)] The closed container to be tested is immersed in a gaseous fluid under pressure and thereafter directly immersed in a liquid at lower pressure than the gas, leaks being indicated by bubbles rising through the liquid. The articles to be tested are hung on a hook 24 on a rod 23 in a transparent cylindrical vessel 1 containing liquid 25. The cylinder has top and bottom liquid tight closures 6, 7, connected by bolts 9, 10, the closure 7 having a stand 8. Fluid under pressure is admitted through a cock 16 until the desired pressure is indicated by a gauge 13. The cock 16 is then closed and the rod 23 lowered opening a release valve 17. The articles are lowered into the liquid and leaks revealed by bubbles. A safety valve 14 is fitted.
