Abstract: The device for electromagnetic radiation treatment of a reactive medium includes an electromagnetic radiation generator, a reactor containing the reactive medium, and a device for transmitting the electromagnetic radiation generated by the generator to the reactive medium contained in the reactor. The device includes a wave guide for transmitting the electromagnetic radiation from the generator and a coupling means arranged to allow transfer within the reactive medium of the electromagnetic energy transmitted by the wave guide. The wave guide includes a curved segment in a general “U” shape forming a return loop from the wave guide. The device further includes a separation wall that isolates the generator form the reactor, with the reactor being connected to the curved segment. The curved segment extends at least partially from one side of the separation wall to the opposite generator.

Abstract: Output amplifier stage (1) of a high frequency generator (1) with tube (2) operating in class B or C has its output (5) looped back on the input (4) by means of a coaxial line (31) with a length equal to approximately the wave length corresponding to the operating frequency. The apparent gain of the amplifier stage (1) is thus increased and the output power from an intermediate amplifier (24) can be correspondingly reduced, amplifying a stable signal at the operating frequency.

Abstract: The invention consists of the following steps:(a) continuously feeding n1 containers with fresh liquid egg white and n2 containers with fresh liquid egg yolk, the containers having the same shape and being made of a material inert to microwaves, the sum of n=n1+n2 being equal to at least two and n1 being either equal to n2 or different from n2 by one unit,(b) subjecting each liquid egg product to the action of microwaves so that it coagulates in the container, in the form of a homogeneous layer, without however reaching the hard cooked state,(c) extracting the layers from the containers and superposing the extracted layers so that a layer based on liquid egg white alternates with a layer based on liquid, egg yolk, and(d) subjecting the superposed layers to a complementary heat treatment to achieve the desired degree of cooking while at the same time ensuring the complexing of the different layers.
