摘要:
The invention relates to a method for producing a metallised substrate (1) which consists at least partially, and preferably entirely, of aluminium and/or an aluminium alloy. A conductive paste (3) is applied to at least some sections of a surface (2) of said substrate (1); in a first firing phase (B i ), the conductive paste (3) is exposed to a substantially continuously increasing firing temperature which is increased to a predefinable maximum firing temperature of less than approximately 660 °C; in a second firing phase, the conductive paste (3) is substantially exposed to said predefinable maximum firing temperature for a predefinable time period; in a cooling phase, the conductive paste is cooled down; and in a post-treatment phase, a surface (4) of the conductive paste (3) is mechanically post-treated, preferably brushed.

Es wird ein Verfahren zum elektrisch leitenden Verbinden von zwei supraleitfähigen Kabeln (1,2) angegeben, die jeweils mindestens zwei konzentrisch zueinander angeordnete und jeweils von einem Dielektrikum umgebene supraleitfähige Leiter (2,4) sowie einen über dem äußeren Dielektrikum angebrachten, elektrisch wirksamen Schirm (6) aufweisen. Die zu verbindenden Leiter und Schirme werden an den Enden der beiden Kabel (1,2) zunächst von umgebenden Schichten befreit und danach elektrisch leitend miteinander verbunden. Die Enden der beiden Kabel (1,2) werden dazu derart nebeneinander und parallel zueinander angeordnet, daß ihre freien Enden in entgegengesetzte Richtung weisen und ihre Leiter zumindest annähernd auf gleicher Höhe nebeneinander liegen. Die beiden Kabel (1,2) werden relativ zueinander festgelegt. Je zwei Leiter der beiden Kabel werden durch sich quer zu ihrer Achsrichtung erstreckende, elektrische Kontaktelemente (10,11,12) elektrisch leitend miteinander verbunden. Die Schirme (6) der beiden Kabel (1,2) werden mittels separater Kontaktelemente (13,14,15) durchverbunden und die beiden derart behandelten Kabelenden werden beim Aufbau einer Übertragungsstrecke für elektrische Energie gemeinsam in einem Gehäuse (16) eines Kryostats angeordnet, das beim Betrieb der Übertragungsstrecke von einem fließfähigen Kühlmittel mit elektrisch isolierenden Eigenschaften durchströmt wird.

Handling units (205) are movable along transport paths and each unit comprises a rotatable reel for coiling/uncoiling of cord-like goods. The reel comprises an axle provided with a coupling element in at least one end, said element being connected to a driving device (250) in a coiling station (203) or to a braking device (240) in an uncoiling station (209-212). The transport path connects a plurality of coiling/uncoiling stations with a buffer storage (220) for handling units in an integrated handling system comprising one or several production lines (201, 202) for cord-like goods, preferably for communication cable or power cable. The transport path includes turntables (204, 206), carriages for parallel movement (216), bypassing units (217) and lifts to provide passages for the units from one part of the path to other parts. Control units (208, 213) are attached to a computer to control the movement of handling units on the transport path and the engagement and disengagement of units to and from driving and braking devices in the stations.
