Abstract: The invention describes a device and a method for internal coating of cavities of workpieces by thermal spraying, comprising a burner for spraying a coating material, the burner being received on a positioning device for allowing positioning at least in one direction, and further comprising a rotary plate, which can be driven in rotary fashion and on which is provided a workpiece holder for a workpiece that can be positioned relative to the burner by means of a guiding device. The guiding device comprises at least one first linear guide with a first drive means for positioning the workpiece holder, and at least one second linear guide with a second drive means for positioning a balancing weight. The first and the second drive means are driven in opposite senses, which guarantees continuous balancing of the masses when the workpiece is displaced.

Abstract: The invention relates to a ceramic cooktop comprising a cooking plate (12) made of glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer (22) and an insulating layer (14) that is located between the cooking plate (12) and the heat conductor layer (22). The insulating layer (14) consists of a plurality of individual layers (16, 18, 20) that each have a porosity that decreases toward the heat conductor layer (22).

Abstract: A wear component in a laminar structure, particularly one of a drainage strip, a deflector, a foil or a suction strip in a paper or a cardboard machine, where on at least one of its partial surfaces a medium that causes wear, in particular a fluid or a material web, such as machine clothing in the form of a sieve or a felt in the machine is applied. The wear component including a beam part being made of at least one of plastic, high-grade steel, copper, nickel, aluminum, zinc, and/or an alloy of the foregoing. The wear component also including an infeed area with an infeed angle &bgr; for the medium of less than 90° and at least one low-wear layer on at least one of the partial surfaces. The low-wear layer being made of a material from a class of self-fluxing alloys. The low-wear layer being at least partially thermally re-melted.

Abstract: The invention discloses a ceramic cooktop comprising a cooking plate made of a glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer and an insulating layer that is located between the cooking plate and the heat conductor layer. Onto the cooking plate a thermally sprayed bonding layer is applied, before further layers are applied.

Abstract: The invention relates to a ceramic cooktop comprising a cooking plate (12) made of glass ceramic or glass. The ceramic cooktop also comprises an electrical heat conductor layer (18), an insulating layer (16) that is located between the cooking plate (12) and the heat conductor layer (18), and an electrically conductive intermediate layer (14) between the cooking plate (12) and the insulating layer (16). The intermediate layer (14) is a thermally sprayed layer consisting of an electrically conductive ceramic material, preferably of an oxide layer that is rendered electrically conductive by oxygen loss occurring during thermal spraying, or of a cermet.

Abstract: The invention relates to a coating for tools that are used to process heat treated glass, e.g., molten glass or the like, to reduce the adhesion of said glass. The coating consists at least partially of a system of carbon-based layers and/or hard materials containing carbon.

Abstract: An ozonizer is disclosed, having a first electrode and a second electrode between which a discharge gap is formed, a dielectric being arranged between the first electrode and the second electrode. The dielectric comprises a support element made of glass or glass ceramic, onto which a thin dielectric film on the order of up to 100 &mgr;m is applied. The use of glass or glass ceramic as the dielectric, in conjunction with an additional thin ceramic dielectric film, allows a considerable improvement in the ozone concentration in the carrier gas, simultaneously with a good ozone yield.
