Patent DE-3734314-A1 (DE)
Title: Drum-type machine
Inventor: FLAMME JOHANNES
IPC: D06B3/30
Filed: 1987-10-10
Abstract: The invention relates to a drum-type machine, especially for the treatment of dyeing material, such as, for example, textiles. In order to reduce the mechanical loads on the dyeing material which occur in conventional drum-type machines as a result of the high rotational speeds of the drum, it is proposed to circulate the dyeing agent in a closed circuit (12, 13, 14, 6). By means of a pump (13), the dyeing agent is fed to a distributor pipe (6) extending axially within the drum (2) and passes via orifices (15) in the distributor pipe (6) into the interior of the drum (2) filled with the dyeing material. After flowing through the drum (2) and therefore through the dyeing material primarily in the radial direction, the dyeing agent returns to the pump (13) via a suction line (12). <IMAGE>

Title: Method and apparatus for applying layers of high-temperature superconducting material to substrates
Inventor: GUNZELMANN KARL-HEINZ DIPL ING
IPC: C23C4/11
Filed: 1988-02-26
Abstract: The application of HTSC material to workpieces can be effected by thermal spraying of ceramic powders having superconducting properties as the starting material onto substrates of any shape required, a continuous covering layer thus being applicable. Hitherto, the coated workpieces then had to be sintered under an oxygen atmosphere in order to regenerate the superconducting properties. According to the invention, thermal spraying is carried out under an oxygen atmosphere with an adjustable oxygen partial pressure. To this end, in a first embodiment, the spray nozzle (13, 23), required for spraying, of the spray appliance (10, 20) can be extended by an inert-gas (protective-gas) tube (30) as an attachment part which encloses the entire volume between the orifice of the spray nozzle (13, 23) of the spray appliance (10, 20) and substrate (1) and to which oxygen (O2) can be admitted. In a second embodiment, there may be a large-volume chamber (60) into which the spray appliance (10, 20), the substrate (1) and further aids for carrying out the coating process under an oxygen atmosphere may be introduced. <IMAGE>
