Title: Reduction of energy consumption by industrial furnaces - by using combustion gases to heat combustion air
Inventor: KNAPPE OTFRIED DIPL ING
IPC: F23L15/04
Filed: 1990-03-15
Abstract: The operating temperature of a forging furnace, or a heat treatment furnace or a brazing furnace, is increased without using any additional fuel.

Patent DE-4033603-A1 (DE)
Inventor: PEPPEL MICHAEL DR
IPC: H02H7/122
Filed: 1990-10-23
Abstract: A method is proposed for protecting the turn-off semiconductor power devices of an invertor, whose input is connected to a DC intermediate circuit, in a three-phase bridge circuit during output short-circuits, an intermediate circuit short-circuiting device being provided at the input, and output inductors being provided at the output of the invertor. In the event of an output short-circuit, all the turn-off semiconductor power devices of one phase are switched off by turn-off signals if this phase is involved in the short-circuit, and the measured value of the load current at the instant when the short-circuit is identified is less than a first limiting value which can be predetermined. All the turn-off semiconductor power devices of a phase which is not involved with the short-circuit are switched off by turn-off signals. The turn-off semiconductor power devices of a converter phase which is involved with the short-circuit maintain the instantaneously existing switching state, by means of extinguishing switching-off signals, if the measured value of the load current of this phase exceeds the first limiting value, an extinguishing switching-off signal having precedence over a turn-off signal. The intermediate-circuit short-circuiting device is switched through when the measured value of the load current of a given converter phase exceeds a second limiting value which is above the first limiting value. <IMAGE>

Title: Deep drawn sheet metal workpieces - are mfd. by continuous adjustment of holding down force of sheet metal blank
Inventor: HIPP THOMAS DR
IPC: B21D24/10
Filed: 1990-12-01
Abstract: The press has a ram (1) and a ring (2) for the deep drawing of sheet metal workpieces. It has a hydraulically actuated device  (3) by a hydraulic cylinder pressing on teh holders ring (3) for holding downthe sheet metal blank. The force exerted on the blank is initially low. A sensing device senses when any puckering of the sheet metal occurs and actuates the hydraulic pressure control system (6-14) so that the pressure is increased. The holding down force exerted by the hydraulic cylinder (11) is then held at this level until puckering recurs. The holdind down force is then further increased to eliminate puckering. This process of stepwise increases in the holding down force, is repeated until the deep drawing operation is completed. USE - Deep drawing of sheet metal workpieces.
