  • Patent number: 9957239
    Abstract: An integrated process for the synthesis of urea and melamine, wherein: urea is synthesized with a stripping process in a high-pressure synthesis loop comprising a reactor, a stripper and a carbamate condenser, and the urea solution leaving said stripper is sent to a recovery section to produce a concentrated urea product and a recovered carbamate solution; at least part of said urea product is converted to melamine, and the off-gas from the synthesis of melamine are recycled to the urea synthesis by mixing with the gas phase from the stripper and with said recovered carbamate solution, thus forming a mixed flow which is then condensed in said carbamate condenser, and the condensate is eventually directed to the reactor.

  • Patent number: 8517339
    Abstract: Interference fit assembly of a first metal part and a second metal part, wherein the first metal part has a recess with an inner contact surface, and the second metal part has an outer contact surface being coupled to the inner contact surface by an interference fit. At least one of the contact surfaces includes a surface layer including a diamond-like carbon. In a method for producing an interference fit assembly the surface layer is applied on at least one of the contact surfaces by a Physical Vapor Deposition or a Chemical Vapor Deposition process with the surface layer having the diamond-like carbon.
