Abstract: A device for treating a product with microwaves includes a treatment chamber, in which the product can be transported along a transport path in a transport direction through the treatment chamber, and a microwave radiation device arranged in the treatment chamber, by means of which microwaves coupled into the microwave radiation device can be radiated, which act on the product, wherein the microwave radiation device includes at least one coaxial conductor which protrudes into the treatment chamber, or is arranged therein, with an electrically-conductive internal conductor and an electrically-conductive external conductor, wherein the external conductor, arranged coaxially, surrounds the internal conductor in a spaced manner and includes at least one opening, which enables an emission of microwaves from the coaxial conductor through the opening on to the product.

Abstract: A device is provided for generating plasma by microwaves for CVD coating a substrate having a vacuum container into which a reaction gas can be fed and an electrical conductor arranged therein which is connected on each of both ends thereof to a device for coupling microwaves and to a voltage source with which a difference of potential can generated between the electrical conductor and the surrounding vacuum container. The electrical conductor is electrically insulated from the devices for coupling microwaves. The electrical conductor has a rod-shaped design or a curved run. The electrical conductor is connected to the voltage source via a feedthrough filter. The device for coupling microwaves expands in a funnel shape toward the electrical conductor and is partially or completely filled by a dielectric material. The device for coupling microwaves has groove-shaped recesses running along a circumference.

Abstract: The invention relates to a method for the production of shaped foam bodies, comprising: provision of a composition having foam particles and binder; introduction of the composition into a space which is bounded on at least one side by a pressing surface; and exertion of pressure onto the composition by means of the pressing surface. The method further comprises irradiation of microwaves through the pressing surface into the composition, while pressure is being exerted onto the composition. The invention furthermore relates to a device for carrying out the method according to the invention, having: at least one pressing surface and a counterbearing surface lying opposite, between which a space extends which is adapted to receive a composition of foam particles and binder. The pressing surface and counterbearing surface adjoin the space directly.

Abstract: The aim of the invention is to provide an alternative to the intensive treatment of a product, especially plasma treatment, in specific areas only. Towards this end, the invention provides a device for producing microwaves for treating workpieces, comprising at least one microwave antenna with an extended conductor for producing alternating electromagnetic fields, a housing that substantially extends over the length of the conductor, and an extended microwave decoupling area which follows the conductor and which is located in the housing. The housing is formed by at least one resonant cavity, which has a long shape and follows the course of the microwave antenna. The resonant cavity has at least one tapering, closed, first crown area and the decoupling area essentially extends in the focussing area of the resonant cavity. An at least non-divergent housing area adjoins the resonant cavity.

Abstract: An apparatus for the heating of pressed stock in the manufacture of boards of material or in the manufacture of veneer panels. The apparatus includes a microwave preheating device having rod antennae disposed in series, reflective shields, and a heating cell configured as a continuous oven in which the introduction of microwaves into the pressed stock takes place via the rod antennae. The rod antennae are attached to lie horizontally and transversely to the direction of production above, below, or above and below the pressed stock within the heating cell. The reflective surfaces are assigned to the rod antennae on the opposite sides of the pressed stock.
