Patent DE-3233829-A1 (DE)
Title: Method for demodulating amplitude-modulated input signals and circuit arrangement therefor
Inventor: HEGELER WILHELM DIPL PHYS
IPC: H03D1/00
Filed: 1982-09-11
Abstract: A method for demodulating amplitude-modulated input signals with digital output of the amplitude information is specified in which, for the purpose of avoiding offset problems which occur in known AM demodulators, a synthetic signal is generated, the frequency of which is matched to the carrier frequency. The synthetic signal is compared with the input signal by analog means and continuously digitally corrected in such a manner that it corresponds to the input signal with respect to its average direct-voltage value, its alternating-voltage amplitude and its phase. The digital amplitude value of the synthetic signal corresponding to the input signal is output as digitised amplitude information of the input signal. A circuit arrangement operating in accordance with this method can be completely integrated.

Title: Method for precharging the commutating capacitors in an invertor with interphase commutation
Inventor: SEGER THOMAS DIPL ING
IPC: H02M7/515
Filed: 1982-09-18
Abstract: In a method for precharging commutating capacitors in an invertor with interphase commutation from a DC source (GL), the capacitor voltage can be doubled by alternately bridging precharging resistors (R1,R2) from a voltage divider circuit. An increase in the commutation capability is achieved in a simple manner by utilising existing elements as a bridging switch (S1,S2).

Abstract: A pressure valve, especially a pressure-limiting valve, pressure-reducing valve or the like, has an insertion body (3), which can be inserted into a hollow valve body, especially into a valve housing (1), and can be positioned on a stop collar (6) on the valve body, an attachment body (8), which can be arranged axially with respect to the insertion body, is used to fix said insertion body in the valve body, has an attachment screw connection (9), and is connected in a positively-locking manner to the insertion body at least in the installed state, and a valve body (11) which has a valve seat and can be clamped in between the insertion body and the attachment body. In order to make the parts which are located between the insertion body and the attachment body accessible, the insertion body and the attachment body can be connected to one another by means of a coupling screw connection (36, 37). Provided behind the individual threads of the coupling screw connection there is in each case one undercut (38, 39) for non-touching engagement of the other individual thread which is longer in the axial direction than the individual thread engaging therein (Fig. 1). <IMAGE>

Patent DE-3307693-A1 (DE)
Inventor: TROESCH JACQUES J DIPL ING
IPC: G01R19/00
Filed: 1983-03-04
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.
