Title: Measuring process for electric signals using a series-parallel feed-back circuit, and application of this process or circuit to the measuring of voltage sources with extremely high internal impedances
Inventor: TROESCH JACQUES J
IPC: G01R19/22
Filed: 1984-03-01
Granted: 1987-06-11
Abstract: For measuring voltage sources with capactive internal impedance (ZG) the voltage source is connected to a charge amplifier (7) whose input capacitance comprises a vibrating capacitor (C(t)). The output of charge amplifier (7) is connected in series with negative feedback via a regulator to the input of the measuring circuit. The frequency response of this transmission line (7, PID) is designed so that a closed regulating circuit has a good follower behavior, at least up to signal frequencies corresponding to the exciting frequency of vibrating capacitor (C(t). The vibration of the capacitor causes an amplitude-modulated alternating signal with the voltage across said capacitor to appear at output (A). This signal is filtered out (13), amplified (15), and amplitude-demodulated (17). The demodulated signal is filtered, and supplied through a high-ohmage resistance (R) as a current to the current summation node of charge amplifier (7). By heterodyning on the one hand the current through the vibrating capacitor and on the other hand a current proportional to the charge on vibrating capacitor C(t), high amplification on the input side of charge amplifier (7) is produced, whereby disturbance factors (IZ) are smoothed out at its input. Residual disturbance factor influences are cancelled out when a current of the exciting frequency (fmod) is passed through in the vicinity of the charge amplifier input.

Title: Bottom electrode for direct current arc furnace
Inventor: BUHLER KARL
IPC: H05B7/06
Filed: 1984-12-22
Granted: 1988-07-07
Abstract: Bottom electrodes (6) of direct current arc furnaces, especially during the overheating phase of the melting process, are subjected to very high thermal stresses. As a result of a melting bath flow brought about by electromagnetic forces, the heat supply from the overheated melting bath (13) to the bottom of the electrode(s) (6) is increased still further. This is manifested in a melting back of the metallic component (6') of the bottom electrode in the direction of the furnace crucible base (4). When both the metallic component (6') and the non-metallic refractory component (7') of the bottom electrode (6) are arranged in the direction of the electromagnetic field, that is, in the peripheral direction of the bottom electrode (6), the length (l) of the electrode component is greater than its width (b). Moreover, two zones form in the operating condition of the furnace; namely, an upper, non-metallic zone (7'), which is formed by the apex (7') of dams (7) projecting into the melting bath (13), and a lower zone, which is formed by the slightly melted-back, metallic component (6'). In this way, the metallic component (6') of the bottom electrode (6) is directly protected from the bath flow, and the intensive heat exchange between the melting bath (13) and the bottom electrode (6) is reduced. By inserting non-metallic, refractory components (7) into the bottom electrode, the periphery or diameter of the latter is increased. This measure reduces the electromagnetic field strength in the transition area from the bottom electrode (6) into the melting bath (13), and consequently an additional reduction in the melting bath flow is achieved at the same time.
