Abstract: 539,705. Disinfectants. MOL, W. E. DE. Feb. 6, 1940, No. 2286. Convention date, Feb. 13, 1939. [Class 81 (i)] [Also in Group I] To destroy parasites in or upon tubers, particularly narcissi, the tubers are subjected in a closed space to treatment under substantial super atmospheric pressure for example, ten atmospheres, with a mixture of carbon dioxide and oxygen, the quantity of volume of the carbon dioxide being less than that of the oxygen. The bulbs may be introduced into an iron tube connected up to a manometer. Carbon dioxide is led in until the manometer indicates a steady pressure of two atmospheres ; oxygen is then introduced until the manometer indicates a steady pressure of ten atmospheres. The bulbs are kept in these conditions for 24 hours whereupon the tube is opened and the bulbs removed. A greater pressure and a longer time of treatment may, when necessary, be employed. The Specification as open to inspection under Sect. 91 refers to the heating of the tubes prior to and during the treatment with the gas mixture. This subject-matter does not appear in the Specification as accepted.
