Title: Surface grinding of two parallel surfaces esp. vehicle brake discs - using fine final finishing phase after partial retraction of tools to receive stress
Inventor: NAGEL WOLF DIPL ING
IPC: B24B7/17
Filed: 1991-07-26
Abstract: The two parallel sides (3, 4) of a workpiece are finished simultaneously by two grinding heads (5, 6) operating in opposing directions.

Patent DE-4219834-A1 (DE)
Inventor: KONSTANZER MICHAEL DIPL ING
IPC: H01H9/56
Filed: 1992-06-17
Abstract: A device (1) is used for switching an electromagnetic switch (2) on in the correct phase in order to close its contacts (3) at the zero crossing of the mains AC voltage in the event of a resistive load. For this purpose, the device has a current measuring device for the current flowing through the magnet coil (5) of the electromagnetic switch (2), a measuring device for the time when the contacts (3) close and, furthermore, measuring devices (6, 7) for the mains voltage zero crossings and the mains voltage amplitude. In addition, an evaluation device is provided which is connected to the measuring devices and has a sequence controller (9) for determining a switching-on time for the electromagnetic switch, for closing its contacts in the region of a zero crossing of the mains AC voltage. The information items coming from the measuring devices are in this case processed in a suitable manner. In a calibration phase, switching-on times which are suitable for closing the contacts at the zero crossing are determined and stored for various operating parameters. These stored data are then available later in the operating phase, so that the electromagnetic switch (2) can always close its contacts (3) at the zero crossing of the mains AC voltage even in changing operating conditions. If the closing time of the contacts should be shifted beyond a preselectable tolerance from the zero crossing of the AC voltage in the operating phase, the switching-on time of the electromagnetic switch (2) can be suitably corrected, and this new value can be stored. <IMAGE>

Title: Sacrificial anode corrosion protection control process - by correcting imposed current to ensure that nominal voltage of closed reference circuit does not deviate far from optimal required potential.
Inventor: MARZLUF WERNER ING GRAD
IPC: C23F13/04
Filed: 1992-09-08
Abstract: The parts to be protected are connected in a circuit with sacrificial anodes and a direct voltage source (1).

The unit (16) holds information relating to the type of water present and the material used in the parts. Measurement is taken over a controlled time span (37) and the average values obtained are stored and fed to the regulating unit (4) which controls the voltage source. Pref., the regulated nominal values are constantly monitored and compared with stored max. optimum values and when they exceed these values a fault is indicated via lights (35, 36). The measured nominal value and the calculated optimal voltage are recorded on display units (21, 26). ADVANTAGE - Ensures greater corrosion protection security by avoiding measuring, adjusting and servicing faults.

Patent DE-4240721-A1 (DE)
Inventor: GROS WALTER
IPC: H04B10/80
Filed: 1992-12-03
Abstract: A measurement system uses optical of the energy for a sensor and analog optical transmission of the measuring signals of the sensor. A feedback control system sets the working point of the optical transmission system for the measuring signals. A zero measuring signal is provided to an electro-optical signal converter, which outputs a corresponding optical analog signal via a optical transmission line to an optoelectric signal converter. The optoelectric signal converter is adjusted to a predefined analysis signal setpoint when the electro-optical signal converter receives the zero measuring signal via a feedback control system. The manipulated variable of the feedback control system is the working-point current of the electro-optical signal converter, which converts the electrical measuring signals into optical signals. This feedback control system can be used to compensate for interference in the analog transmission. An additional feedback control system, which amplifies the analysis signals into output signals, is provided to correct the gain factor of an amplifier unit.
