Abstract

378,299. Condensers. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Dec. 10, 1931, No. 34258. Convention date, June 9. [Class 38 (ii).] Communication with the interior of condenser casings 1 for the purpose of exhausting, while drying under heat, and subsequent impregnation with oil &c. is effected through hollow bolts 4 passing through lead-in insulators 2, 3, tubes being attached for this purpose by means of screw cap 6 and washers 7. Where a gas cushion is left in a sealed condenser the amount of gas space may be determined by the length of bolt extending within the condenser.
