Abstract: An apparatus is provided for uniformly and rapidly heating, pasteurizing and/or sterilizing food products which comprises a conveyor on which the food products are conveyed and a source of radio-frequency radiation which is directed at the food products. The source is connected to shaped electrodes, the shaping of the electrodes and their spacing from the food product being selected in dependence upon the configuration and irradiation required of the product being treated. The food product may be a pre-cooked meal comprising a plurality of constituents and the electrode is then shaped to take into account the geometry of the different constituents and in combination with the spacing of the electrode from the product, takes the heating requirements of the individual components into account.

Abstract: A drive apparatus of a roof structure for a vehicle comprises a drive gear rotatably supported by a casing of the apparatus; a first gear for transmitting the power from the drive gear to a drive section for opening and closing a lid disposed in the roof structure; a rotary member having a control section for switching a switch for detecting the position of the lid; and a second gear for transmitting the power from the drive gear to the rotary member. The drive apparatus has a control device for controlling a drive motor for driving the roof structure.
