Patent number: 10337125Abstract: A heating device for producing carbon fibers from a thread-shaped fiber starting material, wherein the heating device has a central tubular induction heating element through which the fiber starting material is moved. The tubular induction heating element is surrounded by thermal insulation. At least one mid- to high-frequency induction coil is provided outside the thermal insulation, and an inert gas flows through the central induction heating element, in particular, for carbonizing and/or graphitizing the fiber starting material. For energy optimization, a first and a second tube element is provided on the outer side of the thermal insulation. The elements are made of material that is transparent to the induction field of the mid- to high-frequency induction coil and are spaced apart from one another by an annular gap through which the inert gas flows.Type: GrantFiled: February 27, 2015Date of Patent: July 2, 2019Assignees: CLARIANT INTERNATIONAL LTD., LINN HIGH THERM GMBHInventors: Daniel Decker, Michael Woelki, Phillip Schwerdt, Horst Linn, Rudolf Linn, Juergen Kunstmann

Publication number: 20180031321Abstract: A modular furnace, in particular for the oxidative stabilization of a carbon fiber starting material comprising a cuboidal furnace chamber, on the upper face of which first deflecting rollers are arranged in a mutually spaced and parallel manner and on the lower face of which second deflecting rollers are arranged in a mutually spaced and parallel manner such that the carbon fiber starting material runs upwards and downwards in a laterally adjacent and slightly spaced manner so as to meander vertically in the area of the furnace chamber. A carbon fiber inlet locking device and a carbon fiber outlet locking device are provided on the upper face of the furnace chamber, and an air guiding device is connected to the furnace chamber. A supply air portion of the air guiding device is connected to a vertical air inlet side of the furnace chamber, and a discharge air portion of the air guiding device is fluidically connected to a furnace chamber vertical air outlet side opposite the vertical air inlet side.Type: ApplicationFiled: January 26, 2016Publication date: February 1, 2018Applicants: CLARIANT INTERNATIONAL LTD., LINN HIGH THERM GMBHInventors: Daniel DECKER, Michael WÖLKI, Phillip SCHWERDT, Horst LINN, Rudolf LINN, Jürgen KUNSTMANN

Patent number: 8093537Abstract: A process for the production of short cooking time rice is characterized by that hulled rice of at least 10% moisture content, if required in packaging suitable for ready cooking, is heat treated for 1 to 30 minutes continuously or interrupted by equal or alternating capacity microwave radiation, to reach maximum 130° C. An apparatus for the production of short cooking time rice has a microwave furnace with a tunnel made from a suitable material, wherein the rice packed into packages is movable within the tunnel by a conveyor. Regarding the easy and short process, a remarkable energy saving is possible.Type: GrantFiled: April 24, 2009Date of Patent: January 10, 2012Assignees: Linn High Therm GmbH, Alfoldi Malomipari RT.Inventors: Horst Linn, Andras Vass, Ivanne Pallai, Gyula Fazekas, Janos Kovacs, Istvan Edes
