Abstract

1,059,954. Diaphragm pistons. DUNLOP RUBBER CO. Ltd. Dec. 23, 1963 [Jan. 10, 1963], No. 1140/63. Heading F2T. [Also in Division H1] A seal of a container comprises two barrier layers 5, 6 having spaced-apart opposing surfaces, each layer having one or more flexible regions provided with a fold 7a, 6a to allow the seal to take up expansion of the container contents. As shown, the seal is clamped between the flanges of casings 1 and 2, the latter containing transformer oil 26 of a high voltage electrical transformer. The barrier layers are in the form of a diaphragm 5 of neoprene and a sleeve 6 of butyl rubber, these being supported by rigid members 12, 18 spaced-apart by spacers 27. Upon expansion of the oil, the seal is moved upwardly towards the position shown dotted. The air-space between the layers 5, 6 is filled with a desiccant 28 such as phosphorous pentoxide or silica gel to prevent moisture from reaching the oil. As decreases in volume occur in the air-space the increased pressure in the air-space causes the member 18 to lift and so provide compensation. If desired, a breathing hole may be provided in the sleeve 6 in such a position adjacent the member 18 that, upon expansion of the oil, it becomes exposed to the atmosphere in the casing 1.
