Patent DE-3469251-D1 (DE)
Title: Method and device for controlling the conducting state of a gto thyristor
Inventor: PEPPEL JORG-MICHAEL DR
IPC: H02M1/06
Filed: 1984-11-14
Granted: 1988-03-10
Abstract: A method and apparatus to maintain the current-conducting state of a gate-turn-off thyristor by appropriate triggering. To maintain the thyristor's current-conducting state reliably and with little ignition energy consumed, a comparator signal is generated as soon as the voltage drop across the thyristor exceeds a preset limit value by a comparator stage. The comparator signal has a preset duration defined by a pulse duration limiting stage, and, if necessary, a subsequent pulse magnitude limiting stage can change the pulse magnitude as a function of the interval between two subsequent ignition current pulses. A controllable current source connected to the thyristor gate is controlled by these magnitude and duration limited pulses, but this controlled current source only triggers the thyristor when the limit value is exceeded.

Title: Roll for consolidating a fibre web
Inventor: WILDT EBERHARD
IPC: D04H1/54
Filed: 1984-04-27
Granted: 1988-04-14
Abstract: A roller for heat- and/or solvent-treatment of fibrous materials has circumferentially extending annuli or spirally arranged rows of coherent or discrete neighboring protrusions each of which has a larger frustopyramidal section nearer to and a smaller frustopyramidal section more distant from the peripheral surface of the cylindrical body of the roller. The taper of facets of the smaller frustopyramidal sections is less pronounced than the taper of the facets of the larger sections, and the distance between the bases of two neighboring larger sections is less than half the height of a protrusion. The top lands of the smaller sections are relatively large and, due to the less pronounced taper of the facets of such smaller sections, the top lands can be reground a large number of times without unduly increasing their areas so that the rate of transfer of heat from the cylindrical body to the top lands and thence to the adjacent fibers is not unduly affected by repeated grinding. The heights of the smaller sections is less than the height of the larger sections. This also promotes satisfactory transfer of heat from the cylindrical body, through the larger sections and to the top lands of the respective smaller sections.

Abstract: A powder-metallurgy method for producing tubular product having at least one surface (l6), preferably an internal surface, thereof clad with an alloy different from and preferably more resistant to destructive media than the material from which the remainder of the tubing is constructed. An assembly (l0) is constructed of a metal tubing (l2) having an internal surface (l6) to be clad and a tubular insert (l4) is mounted generally axially within the tubing (l2) in spaced-apart relation to the internal surface (l6) thereof, which provides a generally annular cavity (l8) between the internal surface (l6) of the tubing (l2) and the tubular insert (l4). This cavity (l8) is filled with metal particles (26) of a composition to be clad on the tubing internal surface (l6). The cavity (l8) is sealed and the assembly (l0) is heated to an elevated temperature at which it is forged to compact the metal particles (26) introduced to the cavity (l8) to substantially full density and metallurgically bond the particles (26) to the internal surface (l6) of the tubing (l2) to provide a desired destructive-media resistant cladding. The forging operation includes passing the assembly (l0) along a feed path having an axis through a forging box having a plurality of hammers (32) evenly spaced around the assembly (l0). The hammers (32) extend and retract radially with respect to the feed-path axis to impart a radial forging action to the assembly (10) as the assembly (l0) passes through the forging box.
