This pre-consolidated spunbonded web (A) is used preferably for making composite nonwoven, more especially hydroentangled composite nonwoven (AJBfC) comprising said pre-consolidated spunbonded web (A), and an absorbent pulp layer (P), and a carded or spunbonded cover layer (C).

Abstract: The spunbonded nonwoven (W) has high elastic recovery properties and comprises a plurality of multi-component filaments. Each filament, preferably of the sheath/core type, comprises at least a first polymeric component and a second polymeric component. The first polymeric component comprises thermoplastic polyurethane, and the second polymeric component comprises an elastic propylene-based olefin copolymer, and more particularly an ethylene propylene copolymer, preferably comprising at least 80 wt % of propylene units. Said spunbonded nonwoven (W) can be easily thermal-bonded with polyolefin-based nonwoven layer(s), especially polypropylene-based layer(s), in order to make a composite nonwoven, particularly suitable for the hygienic industry (diapers, . . . ).

Abstract: The elastic spunbonded nonwoven has high elastic recovery properties and includes a plurality of multicomponent filaments. Each multicomponent filament, preferably of the sheath/core type, includes a first polymeric component extending along the length of the filament in at least a first section of the filament, and a second polymeric component extending along the length of the filament in at least a second section of the filament that is distinct from the first section. The first polymeric component comprises an elastic propylene-based olefin copolymer, and the second polymeric component comprises an elastic propylene-based olefin and has a melt flow rate that is higher than the melt flow rate of the first polymeric component. The elastic propylene-based olefin copolymer for the first polymeric component and for the second polymeric component includes propylene and from 10 to 25 weight % of one or more C2 and/or C4 to C10 alpha-olefin co-monomers.

Abstract: The polypropylene-based thermoplastic fibers are uniform in cross-section, not having any degraded surface skin, and they are heat-weldable at a pressure at a temperature which is lower than the melting temperature, by virtue of internal heating due to the effect of said pressure. They are made of a first constituent with high crystallinity and at least one second constituent, compatible with the first constituent, and of crystallinity that is lower than that of the first constituent. They have a quantity of primary oxidation inhibitor lying in the range 350 ppm to 1000 ppm. Such fibers are made by spinning under conditions that avoid molecular degradation by thermal oxidation at the periphery of the fibers, in particular with cooling that is rapid immediately on leaving the extrusion head. The non-woven fabric obtained by heat-bonding such fibers is characterized by weld points that are in the form of a polymer laminate that is uniform and transparent.

Abstract: To produce at least one perforation in a non-woven sheet (N) of fibers or filaments, the sheet (N) is brought into contact with a perforated cylinder (2), equipped with at least one insert (8). Each insert includes, at one end, a plane surface (S), and is provided with a recess (8b) which emerges in the plane surface (S), and which has a sharp edge (8g) formed by the intersection of the inner surface (8f) of the recess (8b) with the plane surface (S). A perforation in the non-woven sheet (N) is obtained by cutting out a portion (P) of the non-woven sheet (N) by shearing of the fibers or filaments of the non-woven sheet (N), between the sharp edge (8g) of the insert (8) and a perforating member (9) driven simultaneously in translation and in rotation about its own axis.

Abstract: Known methods involve applying a layer of particularly highly absorbent fibers such as woodpulp on a carrier nonwoven and then compacting the composite nonwoven with the aid of water entanglement. One disadvantage of the compacting method is the high woodpulp fiber loss and the associated purification of the circulating water for the entanglement device. According to the invention, a fine layer of microfibers is initially applied before applying the woodpulp fibers. The microfibers are evenly distributed on the carrier nonwoven using, for instance, a meltblown process and the woodpulp fibers are only then applied in the separating layer. The water during entanglement can no longer merge the woodpulp fibers into the carrier nonwoven due to the fact that the microfibers act as a barrier.

Abstract: A switching arrangement for activating a plurality of electrical devices connected to a communication line. The switching arrangement monitors the communication line for the reception of activation signals, and also transmits activation signals to the communication line. The switching arrangement activates an electrical device (from the plurality of electrical devices) connected to the communication line, in response to the detection of the an activation signal, to shift the electrical device from a dormant state (in which electrical consumption by the electrical device is minimized) to a normal, functional operational state (in which a maximum electrical consumption of the electrical device occurs) only when the electrical device is actually being operated. By switching the electrical device between a dormant state and an operational state, the amount of electrical power required to operate the plurality of electrical devices is reduced.

Abstract: A method for correction errors in radar systems that operate using a crossfeed principle (CFR), in which echo signals are directly received from flying objects, such as an aircraft. In particular, the present invention is used in connection with low-flying objects, in which radar signals are indirectly reflected from the surface of the earth to an antenna of the radar system. Correction terms are determined and weighted, using correction factors, so as to improve the capability of the crossfeed radar system to accurately determine the exact elevation of the flying object. The correction factors that are used to improve the accuracy of the radar system are based upon sea state numbers, or Beaufort numbers, which vary in relation to the shape and/or structure of the reflecting surface.

Abstract: A method and apparatus for conducting a conference call among a plurality of subscriber stations. Each subscriber station contains a transmitter, a receiver, and an auxiliary receiver. An output of the auxiliary receiver can be selectively connected to an adding member that is located between a microphone and an input of the transmitter. The subscriber stations establishing the conference call connection form a transmission chain. Each subscriber station involved in the conference call, with the exception of the first subscriber station on the transmission chain, receive a user signal of a preceding subscriber station. The user signal of the preceding subscriber station is added to its own user signal to produce a compound signal that is transmitted to the next subscriber station on the transmission chain. A compound signal created in the last subscriber station of the transmission chain is supplied to the receiver of all the subscriber stations on the transmission chain.

Abstract: A radar system, such as a tracking radar installation or other radar installation which is of the pulse compression type, transmits data during transmission of the radar signal. The data is transmitted by inserting, into the radar signal, at least one short nonpulse interval. The position of the nonpulse interval within the radar pulse can be modulated.

Abstract: An attenuation network comprises a T or a .pi. network and first and second regulating circuits for controlling it. The T or .pi. network has at least two variable resistances. A switch S1 permits selection of a desired attenuation value which is set through the operation of the second regulating circuit on the T or .pi. network, while the first regulating circuit acts on the T or .pi. network such that its input and output resistances are kept constant.

Abstract: A frequency synthesizing device generates periodic electrical oscillations of a frequency that can be arbitrarily determined, in which, after changing the frequency and resetting it to any desired value that has previously been generated, phase coherence is maintained. In addition to the elements of a direct digital frequency synthesizing device, the arrangement according to the invention has a time measuring unit (ZME) and a control logic (SL). The time measuring unit (ZME) periodically counts through a time interval from t=0 to t=t.sub.z and transmits the count status or a time signal to the computing system (R). The frequencies f.sub.i to be emitted and the time interval from t=0 to t=t.sub.z are chosen in such a manner that the phases of all the frequencies f.sub.i take on a constant value at the time t=0. This makes it possible to compute the coherent starting phase .phi..sub.N, so that the new frequency f.sub.N can be generated, with phase coherence, as of the time t.sub.

Abstract: A frequency synthesizing device comprises two reference frequency generators RG1 and RG2, an offset stage OS and a phase-locked loop PLL. In the phase-locked loop, which operates as a tracking filter, the output frequency fs.sub.A is generated by the addition of the frequencies f.sub.RG1 and f.sub.OS. The output frequency fs.sub.A has a very high spectral purity, since all interfering spurious signals are blocked by the tracking filter. By a proper selection of the reference frequencies f.sub.RG1, f.sub.RG2 and f.sub.OR, it is ensured that all interfering spurious signals lie outside the bandwidth B.sub.TF of the tracking filter and are accordingly blocked. As a result, it is not necessary to filter the signals S.sub.RG1, S.sub.RG2 and S.sub.OS.
