Abstract: A device for stirring molten metal in a continuous casting operation in which the molten metal flows in a controlled manner from a reservior, via a spout, to an ingot mold is presented. The stirring device comprises an electro-magnetic inductor which is displaceable transversely in relation to the metal casting line with its magnetic core consisting of a unitary part with several arms arranged around the casting line at a distance from the latter and directed radially inwardly towards the casting line. In accordance with a first embodiment of the present invention, the core has three arms which are each provided with an electromagnetic winding and which form, between them, angles of 120.degree.. The inductor is preferably arranged around the spout, but similar inductors may be arranged around the casting line in the secondary cooling zone.

Abstract: An electronic flash attachment accommodates plural circuits, one of which is used for differing types of cameras and others of which are each used for a particular respective type of camera. The flash attachment has a contact socket with contact elements electrically connected to the plural circuits. A connector module is removably provided on the flash attachment and can be replaced by a different connector module for a different type of camera. The connector module has a first face provided with first contact elements which engage those of the contact-socket contact elements associated with those of the plural circuits which are to be used with the type of camera for which the connector module is intended. The connector module has a second face configured to be received in a camera's flash-attachment mounting shoe and provided with second electrical contacts electrically connected to the first and so disposed as to conductively engage the contact elements with which such mounting shoe is provided.
