Title: Direct-current arc furnace plant
Inventor: WANNER ERNST
IPC: H05B7/148
Filed: 1993-03-25
Abstract: The direct-current arc furnace plant comprises a furnace vessel (8), one or more arc electrodes (7) connected as cathode, one bottom contact (12) connected as anode, a furnace transformer (2) and a current rectifier arrangement (5) for supplying the furnace, as well as an electrode-controlling device (E) and a current controller (I). An inductor (6) is inserted in the main direct-current circuit. There is cascaded a voltage control circuit (F) to the current control circuit (I), the output voltage of the current controller (14) supplying the desired value for the voltage controller (24). There is connected downstream of this voltage controller (24) a filter (25) which is tuned to the flicker frequency and has a frequency response curve matched to the frequency sensitivity of the human eye. As an option, an additional control voltage signal Uflick supplied by a flicker measuring device can be injected into the current control circuit (F). As a result of a furnace control system constructed in this way, an optimum introduction (supply) into the furnace can be achieved of the active power (effective power) supplied by the furnace transformer (2) and the current rectifier (5) and at the same time output changes (level changes) and thus reactive load changes leading to flickers can be damped as a function of frequency. <IMAGE>

Patent DE-4336553-A1 (DE)
Title: Compressed-gas operated shooting weapon
Inventor: ROEMER PETER
IPC: F41A21/12
Filed: 1993-10-27
Abstract: A calibration device for the projectile in the form of a projectile bearing is arranged in the rearward region of the bore of the barrel of a shooting weapon, the diameter of which projectile bearing is slightly smaller than the diameter of the bore of the barrel. The projectile is inserted into the barrel with the aid of a horizontally moving loading pin, and is pressed into the constricted projectile bearing. In this case, the projectile is calibrated to a diameter which is slightly smaller than the diameter of the bore of the barrel. The consequence of this is that the projectile flies through the bore of the barrel virtually without touching it when it is fired, so that the friction drag is considerably reduced and the Vo and the firing precision are improved.
