摘要:
In a filter apparatus 1, a central filter rod 6 is arranged in the interior 14 of a filter housing 2, the diameter d of which filter rod tapers in the direction of flow of the plastic melt. On the filter rod 6 are arranged filter discs 7 which are parallel to one another and have outer and inner diameters of equal size. The filter apparatus 1 operates as a continuous-flow filter apparatus in which the plastic melt flows in via an intake 4 and flows out via an outlet 5. A filter housing wall inner surface 3 tapers in the direction of flow of the plastic melt, so that a gap width h.sub.a (x) between a filter disc outer rim 8 and the filter housing wall inner surface 3 decreases in the direction of flow of the plastic melt.

A device for laying a molten film 3 emerging from a slot die 2 onto a rotating take-off chill roll 1 has at least one electrode which is arranged parallel to and at a short distance from the surface of the take-off roll 1 and to which a high voltage in the range from 4 to 12 kV is applied. This electrode is, for example, a metal strip 5 which has a tapering sharp edge 6 that is oriented toward the surface of the take-off roll 1. In addition to this metal strip 5, a second electrode 27 is arranged at a distance from the surface of the take-off roll. This second electrode is a metal strip without a strip edge and has applied to it a voltage of a magnitude that is equal to or different from that of the metal strip 5. As a result, electric fields are formed in addition to the electric field from the one metal strip electrode 5.

This electrode is, for example, a metal strip 4, which has a tapering strip edge 6 this is directed toward the surface of the take-off roll 1. In addition to this metal strip 4, one or a plurality of electrodes 5, 8 and 16 are arranged at a distance from the surface of the take-off roll. These additional electrodes have applied to them an electric voltage whose magnitude is the same as or different from that applied to the metal strip 4. As a result, additive electric fields to the electric field of the one metal-strip electrode are formed.

An object detection system, in particular for a motor vehicle, has multiple object detectors and/or operating modes with which different detection ranges and/or detection zones are detected. In this case, an object detector is preferably a radar sensor which has a relatively large detection range with a relatively small angular detection zone in a first operating mode and has a detection range that is small relative to the first with an enlarged angular detection zone in a second operating mode.

Relative differences between cylinder torque moments are individually determined for each cylinder in a multicylinder internal combustion engine in which individual cylinders may be switched off. The torque moment differences are ascertained indirectly when the engine is subject to inner and outer resistance moments and to the inertia moments of all masses to be accelerated. Under these conditions the crankshaft r.p.m. is measured and the r.p.m. signal is split into components for the individual cylinders by applying the superposition principle of linear systems. The first r.p.m. is determined when all cylinders work. The second r.p.m. is determined with all cylinders but one working and the second r.p.m. is deducted from the first r.p.m. Gradually one cylinder after the other is switched off and the respective differences in the r.p.m. are ascertained. These r.p.m. differences are allocated to the ignition compression and are compared with a difference r.p.m. of a reference cylinder. This comparing provides a torque difference for each cylinder relative to the reference cylinder. The results are then treated statistically, for example by the least square method to determine numerical values which are converted into closed loop control signals for controlling injection fuel quantities for each cylinder so that each cylinder will contribute the same moment component to the total torque moment of the engine.

In order to increase the safety of a robot that may come into contact with other robots, objects or humans, the invention provides that said robot comprises at least two joints and parts that are moveable in relation to each other via at least one joint. At least one sensor (31) is arranged on at least one moveable part (3, 4, 5′, 6, 7), detecting torque. Sensor components (21′, 22.1, 22.2) of the sensor (31) are designed for the redundant detection of a torque, or for the redundant detection of a torque of at least two sensors (31) are provided, and redundant evaluation units are provided for the redundant evaluation. In order to increase safety, the invention further provides a method for monitoring torque on a robot of said kind, wherein at least a torque on at least one movable part (3, 4, 5′, 6, 7) is redundantly detected and redundantly evaluated on at least one moveable part (3, 4, 5′, 6, 7) by means of two sensor components of a sensor (31) or by means of two sensors (31).
