Patent DE-3833896-A1 (DE)
Title: Frequency difference evaluation
Inventor: BENZ KARL
IPC: G01F23/296
Filed: 1988-10-05
Abstract: The present invention relates to a device for determining a specific filling level in a container which consists of two oscillating elements, the outer oscillating element enclosing the inner coaxially, the oscillations of which are damped by contact with the filling material to be measured. The oscillating elements are excited into oscillations in two oscillation planes at right angles to each other. The outer oscillating body has a counter-rotationally symmetrical design so that, when immersed with respect to the oscillation planes, different oscillation changes result which are used for the detection of the filling material.
Patent DE-3839043-A1 (DE)
Title: Process and equipment for producing graphite
Inventor: IMHOF RAINER DR
IPC: B03B9/00
Filed: 1988-11-18
Abstract: Graphite, in particular graphite of fan-like flaky structure, has hitherto been produced from graphite-containing minerals by repeated comminution in pin mills or ball mills, classification and subsequent flotation in successive stages. In this case, however, it was unavoidable that the flaky structure, which is very valuable for the further processing of the graphite, was destroyed. According to the invention, however, the flaky structure of the graphite is preserved during the production of the graphite from graphite-containing minerals by pretreating the graphite-containing minerals before the flotation in an aggregate (5) in which the fan-like flakes of the graphite are separated from one another by circulation and defibration and detached from the accompanying minerals. <IMAGE>

Title: Gas-mixt. combustion chamber with fine-meshed explosion shield - is shaped and otherwise treated to minimise deflagration wave reflection
Inventor: WIESEMES JOHANNES DR
IPC: F23M5/00
Filed: 1989-12-12
Abstract: A combustion chamber enabling gas mixts. to be burned without risk of explosive in an adjacent space contg. the mixt. is sepd.  therefrom by fire-meshed metal, or pref. by carbon fibre  mesh whose reflectivity of deflagration wave fronts is less. The space concerned is further protected from explosion by internal shaping, e.g. conically or as horns, to produce multiple reflections of such waves.

Title: Determining the quality of waste waters - where characteristics of water are continuously measured in non-invasive manner and computer compares measured values with pre-set limits
Inventor: RUDOLPH KARL-ULRICH PROF DR DR
IPC: G01N35/00
Filed: 1990-03-03
Abstract: In a system for determining the quality of waste waters, a number of characteristics and/or constituents are measured continuously and in a non-invasive manner, predetermined limiting values are fed into a programmable storage unit, and an output device compares the measured values with the limiting values and produces an output signal or control quantity. The storage unit and output device may take the form of a computer and the pH value and conductivity of the water are selected as the characteristics to be measured. The redox potential, the turbidity and the oil content may also be selected as characteristics to be measured. Non-invasive optical methods of measurement are used. A separate probe (7) is used for each measurements to be made and these are installed in the inlet (1) to a rain-water tank, a fire-water collecting tank or a buffer tank. These probes (7) are of a self-cleaning type. Where possible, optical probes are used which are above the water surface and do not interfere with the water flow. When the water quality reaches a point where it can no longer be discharged directly into the drainage channel (KA), it is automatically diverted via a pipe (2) into a tank (3). In this tank, the water is sedimented or treated chemically in three separate chambers and when it reaches the required quality, as determined by the probes (M), it is discharged via a pipe (5) to the drainage channel (KA). USE/ADVANTAGE - Used in the monitoring of the quality of waste waters so as to produce a control signal which will operate a pump, a multi-way valve etc. when one of the measured values reaches a predetermined limit.
Patent DE-4008200-A1 (DE)
Inventor: SUESSMEIER GEORG DIPL ING
IPC: H04N7/24
Filed: 1990-03-15
Abstract: To process several television signals for transmission purposes, for example for an optical waveguide cable television distribution network, the television signals are converted group by group as frequency-division multiplex signal into a frequency position which is advantageous for subsequent digitising (AD). The frequency-division multiplex signal is digitised as a composite signal. Due to this processing, the complexity both at the receiver end and at the transmitter end can be kept down without noticeable deterioration in quality. At the receiving end, only one D/A converter (DAG) and one channel group converter (UG') is necessary for one group of channels of television signals. <IMAGE>

A mobile control station (31) determines the operation of the hydraulic cylinders (6). The mobile control station (31) is at the operator's cabin of a crane. ADVANTAGE - The foundation work for the stripper assembly is reduced in comparison with the installation of conventional equipment.
