The covering includes a basic covering which has a web-contacting upper side and an underside, and a plurality of polymer elements. The polymer elements are welded onto the upper side and at least some of the polymer elements are in the form of yarn-shaped and/or tape-shaped polymer elements.

Abstract: A method for testing multiple spatially distributed protective devices of an energy supply network. Each of the protective devices is configured to, in the event of a fault occurring in the energy supply network, isolate the fault in the energy supply network. The method comprises: producing an initial test sequence; outputting of the test sequence to the protective devices; detecting outputs of the protective devices that the protective devices output on the basis of the test sequence; analyzing the outputs and generation of inputs for the protective devices depending on the outputs. If the inputs are not part of the test sequence, these inputs are incorporated into the test sequence and the outputting step proceeds. Otherwise, all outputs of the protective devices are evaluated. Each test sequence comprises inputs in the form of process variables of the energy supply network for at least one of the protective devices.

Abstract: The present invention relates to a method for testing multiple spatially distributed protective devices (SE1, SE2) of an energy supply network (3). Each of the protective devices (SE1, SE2) is configured so as to, in the event of a fault (5) occurring in the energy supply network (3), isolate the fault (5) in the energy supply network (3). The method comprises the following steps: a: production of an initial test sequence. b: outputting of the test sequence to the protective devices (SE1, SE2). c: detection of outputs of the protective devices (SE1, SE2) that the protective devices (SE1, SE2) output on the basis of the test sequence. d: analysis of the outputs and generation of inputs for the protective devices (SE1, SE2) depending on the outputs. If the inputs are not part of the test sequence, these inputs are incorporated into the test sequence and step b is proceeded with, while otherwise step e is proceeded with. e: evaluation of all outputs of the protective devices (SE1, SE2).

Abstract: There is described a fully automatic portable testing device which can be used generally for testing test-pieces to be operated at high voltages and/or high currents, such as current or voltage transducers or transformers for example. For this purpose, the portable testing device comprises a switched-mode power amplifier (3) whose output is connected to a matching transformer (4-7) having a plurality of secondary windings (5-7), which can be changed over. The test-piece on which measurements are to be made is in each case removably connected to the secondary windings (5-7) of the matching transformer. The portable testing device also comprises a control which in particular may have a digital signal processor (8) and/or a controller or computer (9) and which on the one hand controls the power amplifier (3) in a purposive way and preferably also performs an automatic changeover of the secondary windings (5-7) of the matching transformer, in order to generate a desired testing signal.

Abstract: Test system and test method for testing the operability of test samples (7). A selection can be made in a user-specific manner from a plurality of test modules (2a-2c) which are made available, which can be assembled together to a desired test specification. A control module (1) carries out the overall test corresponding to the user-specific test specification, and controls individual selected test modules (2a-2c) in the desired sequence in correspondence to this test specification. Advantageously, there is produced automatically a test report on the test results of the individual selected test modules (2a-2c), which reports in particular embedded in the user-specific test specification.

Abstract: A secondary belt for papermaking. The belt has a framework of protuberances arranged in a semicontinuous pattern to provide a semicontinuous pattern of deflection conduits. The semicontinuous pattern is distinguished from the discrete and continuous patterns of the prior art. The protuberances may be generally parallel, or may provide individual cells within the deflection conduits between the protuberances. Also disclosed is the paper made on such a secondary belt.

Abstract: A two piece garment for collecting bodily discharges is disclosed. The garment has a belt and a disposable assembly which are detachable and reattachable. The belt is intended to be reused, while the disposable assembly is intended to be discarded when soiled. The two components are attached to one another by hook and loop type fastening material, providing for adjustment to fit a wide range of wearer sizes.

Abstract: The present invention is directed to a single lamina tissue paper having visually discernible, large scale patterns made during the drying step of the papermaking process. Particularly, the tissue is made on a blow through drying belt having a pattern of alternating knuckles and deflection conduits. This pattern produces a like pattern of regions in the paper having alternating values of crepe frequencies, opacities and elevations. The differences in these values produces a visually discernible pattern.

Abstract: High bulk, absorbent paper having a relatively high MD elongation at rupture, and a substantially greater stress/strain modulus in the lowest one-third of its range of MD extensibility--preferably when wet--than equally machine-direction-stretchable, purely dry-foreshortened (e.g., dry-creped) paper having substantially identical MD elongation at rupture. The process includes a differential velocity transfer of a wet-laid embryonic web having relatively low fiber consistency from a carrier to a substantially slower moving, open-mesh transfer fabric having a substantial void volume; and thereafter drying the web while precluding substantial macroscopic rearrangement of the fibers in the plane of the web. The differential velocity transfer is effected without substantial compaction of the web by avoiding substantial mechanical pressing, centrifugal slinging, air blasting, and the like.
