Patent number: 9437359Abstract: A reinforcement-free tank for an electromagnetic apparatus, as may be immersed in a fluid is provided. The tank may include a pair of mutually-opposite side walls. Each side wall may have at least one curved segment defining a vertically-curving profile between a top edge and a bottom edge of a side wall. A pair of mutually-opposite end walls. Each end wall may have a substantially vertically-extending semi-cylindrical shape defining a vertically-straight profile between a top edge and a bottom edge of an end wall. A plurality of vertically-extending joining members. Each joining member may be configured to provide a transition between the vertically-curving profile of a side wall and the vertically-straight profile of a corresponding end wall. The walls can withstand vacuum and overpressure conditions which can develop in the tank, without a reinforcing member connected to the walls.Type: GrantFiled: March 11, 2013Date of Patent: September 6, 2016Assignee: Siemens AktiengesellschaftInventor: William Fernando Quintero Restrepo
