Inventor: KOLLINGER RUDOLF DIPL-ING
IPC: F16J15/34
Filed: 1988-06-24
Abstract: The sliding ring seal contains a first ring body (3), which is held fixed and sealed on a wall (2), having a flat, circular first end surface (5) and a second ring body (7), which is held rotationally fixed and sealed on a shaft (1), can be moved in the axial direction and is prestressed by springs (4) against the first ring body (3), the second end surface (6) of which second ring body (7) is likewise flat and circular and rests on the first end surface with a common ring- shaped sealing surface (contact surface). Spirally running slots (10), which are of constant shape and are arranged at the same angular intervals, are machined out of the second end surface (6), which slots (10) extend between the sealing surfaces and, with their inner ends, maintain an interval with respect to the inner boundary line of the sealing surface. By means of a relative rotary movement, a gaseous medium is drawn in between the sealing surfaces and a pressure buffer separating the sealing surfaces is formed. In order to reinforce this pressure buffer, the depth and width of each slot (10) decreases continuously from the outer to the inner end and the slot boundary surface (11a) changes at its inlet edge (12a), located at the rear, at an angle ( alpha ) of less than one angular minute into the sealing surface (6). <IMAGE>

Abstract: In ISDN, the new digital communication system, transmission takes place between the network termination (2) and the terminals (3) via the so-called So interface by means of interface transformers (6, 11). Since some power is also supplied to the terminals via these transformers, current unbalance in the lines (7, 8) or (9, 10) results in bias magnetisation of the transformers. The ISDN requirements on the transformers must therefore also be met in the presence of DC current bias magnetisation. Compact transformers with a simple winding structure which meet ISDN requirements have, according to the invention, as their magnet core material an amorphous Co-based alloy with a permeability of more than 25 000 and less than 95 000. As well as Co, the magnet cores preferably contain essentially Fe and Mn with a total content of 3 to 8 atomic per cent and metalloids in a proportion of 24 to 29 atomic per cent and optionally up to 15 atomic per cent Ni and up to 1 atomic per cent Mo, Cr and/or Ni. <IMAGE>

Abstract: In planetary stranding machines, in which the rotor consists essentially of a supporting tube, to which disc-shaped supporting plates for the rotatably mounted bobbin carriers are connected, for purely constructional reasons the rotor cannot be designed with the necessary bending resistance, thus resulting here in limitations to the maximum permissible rotational speed which lead to a limitation of the production capacity. 
<??>The arrangement on the supporting tube (6) of longitudinal webs (7) directed radially outwards and distributed uniformly on the circumference affords a greater resistance which permits higher rotational speeds. Furthermore, if the supporting plates (12) on the one hand and the axes of rotation (13) of the bobbin carriers (9) on the other hand are arranged at an angle to the supporting tube (6), this produces a considerable reduction of the flight-circle diameter which in turn allows an increased operating speed, so that the production capacity can be increased.
