Abstract

648,736. Transformers. ETABLISSEMENTS MERLIN & GERIN. Dec. 2, 1948, No. 31210. Convention date, Jan. 7. Addition to 648,697. [Class 38 (ii)] A cooling arrangement for electrical transformers embedded in a quartz crystal filling medium comprises plates 1 of good heat conducting materials inserted between the coils 2 of the transformer and in the mass of the filling medium the tank 4 enclosing the coils being provided with vertical tubes 11 open to the surrounding air and located between the heat conducting plates 1. Further heat dissipation may be obtained by turning the extremities 1a of the plates 1 to lie parallel and close to the sides of the tank 4, by providing small perpendicular ribs lb on the faces of the plates 1 and directed towards the tubes 11 ; and by providing ribs 11 on the external walls of the tank. The Specification as open to inspection under Sect. 91 comprises also modifications in which the filling mediums may be materials other than quartz or mixtures of these materials and quartz. This subject-matter does not appear in the Specification as accepted.
