| 20110168431 | ELECTRIC CONDUCTOR AND METHOD FOR MANUFACTURING AN ELECTRIC CONDUCTOR - The invention relates to an electric conductor ( | 07-14-2011 |
| 20100139841 | METHOD FOR THE MANUFACTURE OF A CERAMIC COMPONENT - The invention relates to a method for the manufacture of a ceramic component of desired final geometry using at least a cellulose-containing semi-finished moulded part, which is pyrolysed in non-oxidizing gas atmosphere. In order to manufacture complex components, it is suggested that at least two semi-finished moulded parts are firmly joined either in raw form or after at least partial carbonisation. The joined moulded parts are subsequently machined to achieve the desired final geometry or a geometry corresponding to the desired final geometry plus the machining allowance. Then, the carbon parts are available after carbonisation of the moulded parts in non-oxidizing atmosphere. Alternatively, these can be converted into a CMC composite material in a non-oxidizing gas atmosphere by a metal infiltration process with simultaneous reactive joining of at least two moulded parts. | 06-10-2010 |
| 20100133951 | CARBON BRUSH FOR TRANSMITTING HIGH CURRENTS - The embodiments of the invention relate to a carbon brush for transmitting high currents, having a connecting element for connecting an electrical track and a consumable contact element with a contact surface that is designed to lie flush against a commutator device, wherein the connecting element and the contact element are combined in a layer transition zone aligned perpendicularly to the direction of wear of the carbon brush and form a one-piece moulded body, wherein the connecting element and the contact element have different compositions, such that a carbon component of the contact element is greater than the carbon component of the connecting element and the contact element has a metal component differing from that of the connecting element. | 06-03-2010 |
| 20090305867 | METHOD FOR THE PRODUCTION OF A CERAMIC SUBSTRATE, AND A CERAMIC SUBSTRATE - A method for the production of a ceramic substrate for a semiconductor component, includes the steps of producing paper containing at least cellulose fibers, as well as a filler to be carbonized and/or SiC, pyrolizing the produced paper, and siliconizing the pyrolyzed paper. | 12-10-2009 |
| 20090261687 | METHOD AND DEVICE FOR MANUFACTURING A MULTILAYER COMPRESSION MOULDED ELEMENT - The invention relates to a method and a device for manufacturing a multi-layer compression moulded element and to a compression moulded element which is embodied as a multi-layer carbon brush and has at least a first and a second moulding layer, in which, in order to carry out the method, a multi-component mould which comprises a moulding element and a mould slide arrangement interacts with a moulding die, and in which a mould which is defined by the selected configuration of the moulding slide arrangement in the moulding element is filled by filling moulding segments which are formed one next to the other with moulding material in chronological succession in a transverse direction with respect to the axis of the moulding die, and by the compression moulded element being subsequently formed by moving the moulding die and moulding slide arrangement relative to one another in the mould. | 10-22-2009 |
| 20080214032 | CONTACT ELEMENT - The invention concerns a contact element ( | 09-04-2008 |
