Title: Procedure for establishing load-fill dump for biologically treatable waste - by placing waste in ground depression in layers each provided with drainage pipes and addn. of nutrients
Inventor: WESELOH HEINRICH
IPC: C12S9/00
Filed: 1991-01-28
Abstract: Establishing a land-fill dump for contaminated material which is suitable for biological treatment comprises (a) excavating the soil in the contaminated region and immediately sepg. it in accordance with its degree and type of contamination, (b) segregating the material which can be treated by a microbiological process is from that which can be disposed of without treatment or which needs special treatment, (c) transporting the segregated material to a remote waste material tipping area in the form of a depression (2) in the ground, which has been provided with floor and side wall sealing membranes (3), and which has a seepage water collection and drainage system (5) for the controlled removal of seepage water and gas, (d) classifying the material to be dumped according to particle size by sieving out larger particles, (e) mixing the material with nutrient substrates and loosening agents such as bark, wood shavings, compost etc. and placing it in the dumping area in thin layers (6, 11), (f) intensively microbiologically treating the material in sections by regular turning, chopping and/or mulching, (g) levelling off the area and prepg. it for the dumping of further layers of soil, (h) removing or adding gas, nutrient solution and moisture to the various layers in a controlled manner, and (i) degassing and dewatering all of the layers when the topmost layer (13) is in position. The material in the dump may be injected with oxygen from below. Each layer is covered by a separate sealing membrane (13), below which is placed a degassing layer (7) contg. a system by which gas and moisture can be removed from or added to the dumped material. All of the layers are de-gassed and de-watered together via rising pipes (9, 10, 14) when it is no longer required to add gas or moisture into any of the layers. USE/ADVANTAGE - Used in the disposal of contaminated soil and waste material which can be treated by a biological process. The contaminated earth, which may have to be removed because of construction or de-contaminating operations, is biologically treated in a reliable and dependable manner.
Patent DE-4105516-A1 (DE)
Inventor: LEBOWSKY FRITZ
IPC: H04N5/208
Filed: 1991-02-22
Abstract: In a process for filtering signals, signal amplitudes are assigned to a quantized, two-dimensional reference plane. A wanted signal component is amplified, after uniform components and high-frequency components are filtered out, by adding a filtered signal to an unfiltered input signal. Following frequency-dependent filtering of the signal component to be filtered, components of the signal component whose amplitude is greater than a given threshold value are removed in at least one contour filter step (12). The threshold value is adjusted adaptively in function of the amplitude of the input signal. In addition, the output signal of the contour filter step (112) is subtracted from the output signal of the frequency-dependent filter to obtain the complete filter signal.

Patent DE-4129412-A1 (DE)
Inventor: TURSKI KLAUS
IPC: B60R16/02
Filed: 1991-09-04
Abstract: A process is disclosed for transmitting data in a data processing system with distributed computing nodes (N) interconnected by a serial data bus (BUS) among which objects are exchanged. An object transmitted on a bus is checked at a computing node by several acceptance filters (AF1, AF2, AFm), each of which being associated to at least a receiving buffer (RB1, RBn-1, RBn). After the receiving buffer, the object is stored in a memory (M) associated to a central unit. By hierarchically arranging the acceptance filters, by randomly associating them to the receiving buffers and by defining them as band pass filters or stop filters, it is possible to retransmit in a very flexible way only the desired objects, and thus to obtain an optimal configuration for the administration of the objects of a computing node.

Title: Fly cutter type spline milling machine - has cutter slightly skew to cutter rotational axis to produce virtual clearance between cutter and flanks of slot
Inventor: GARSCHAGEN FRIEDRICH A
IPC: B23F21/20
Filed: 1991-09-30
Abstract: The rotational plane of the cutter is inclinable relative to the workpiece axis about an axis z. The cutter (5), which is in the form of a flat plate with square edges, is set at a slightly skew angle to the rotational axis y, and with its cutting face in advance of a parallel radius drawn from the arbor axis y. The arbor is tilted in the reverse direction about the axis z to compensate for the angular setting of the cutter. The effect of this geometry is to create a virtual clearance between the cutter flanks of the slot, thus avoiding the need to grind a clearance face on the cutter. ADVANTAGE - Cutter is simplified and is cheaper to produce and maintain.

Filed: 1992-05-10
Abstract: A device for supplying doses of a liquid or viscous substance, in particular a lubricant, to a point of consumption, has a transport device which supplies the substance contained in a reservoir to the point of consumption. The transport device has an energy accumulator which can be deformed against an elastic restoring force and which can be transferred by a moving device from a first position where the restoring force is low to a second position where the restoring force is high. The restoring force is then used in order to supply to the point of consumption an accurately defined volume of the substance contained in the reservoir. The volume conveyed per stroke and the number of conveying strokes per unit of time is controlled by an indicator which remains at the point of consumption when the device is replaced.
