Abstract: A method for adhesively bonding shaped elements made from wood-based materials to flexible film substrates, in which i) the side that is to be bonded is mechanically processed, ii) a reactive one- or two-component polyurethane adhesive is applied to the center regions of this side, iii) an aqueous adhesive based on EVA, PVAc, PVOH is applied at least to the outer region of this side, and iv) this side is bonded to a flexible substrate as an edge coating.

Abstract: The invention concerns a method of operating a broadband link for the exchange of data (DAT) between a mobile terminal (MS) and a network-side mobile radio facility (MSC), as well as the mobile terminal (MS), the network-side mobile radio facility (MSC) and a mobile radio system. Two or more radio channels to the mobile terminal (MS) are established and assigned as subchannels (C1 to CN) to the broadband link. The data (DAT) are then transmitted via the subchannels (C1 to CN) between a terminal-side entity (ENMT) and a network-side entity (ENNET) of a communications layer (L2), where the entities (ENMT, ENNET) exchange the data (DAT) as data packets (FRDAT1, FRDAT2) in accordance with a transmission protocol, and control the distribution of the stream of data packet to the subchannels (C1 to CN) as well as its recombination. The protocol (PROT) defines and supports two or more different packet types for transportation of the data.

Abstract: A tow of melt spun filaments and a method for treating such filaments to produce a tow of uniformly crimped filaments having a high initial modulus by heat setting and stuffer box crimping includes the steps of heat-setting the tow, spraying the hot-heat-set tow with an aqueous fiber finish to effect shocklike cooling of the tow, passing the sprayed tow to a pair of squeeze rolls in whose nip it is kneaded through using a defined nip pressure and squeezed off to a fiber finish pickup of 0.7 to 7% by weight of the tow weight, heating the squeezed-off moist tow on a heated multiroll arrangement in such a way that it leaves the multiroll arrangement with a moisture content of 0.5 to 5% by weight of the tow weight and a temperature of 40.degree. to 1000.degree. C., feeding the tow with this moisture content and this temperature to a crimping machine and crimping it.

Abstract: Described are thread-guiding components for apparatus for producing, treating and processing fiber materials, having a surface which comes into contact with the fiber materials defined by certain values of the maximum averaged roughness depth R.sub.z and the values of the load-bearing proportion calculated for certain depths of cut. The defined surface comprises a cermet material. Preferably there is additionally deposited on it an outer layer, from 0.1 to 10.0 .mu.m in thickness of nitrides and/or carbides of titanium or chromium. The components are notable for significantly enhanced long-term stability of the surface properties. The components are preferably godets.

Abstract: A modified activated sludge system is provided wherein wastewater is treated to reduce BOD, nitrogen, and/or phosphorus. The disclosed system features a zone sequence nitrification/denitrification, with nitrification induced by recycling mixed liquor that contains a significant concentration of oxygen and nitrifying bacteria. With a further modification, the main treatment zones of the treatment system are split into two or more parallel treatment trains that are either high-loaded with BOD or low-loaded with BOD. The high-loaded sections facilitate the sludge generation and BOD removal, while the low-loaded sections are operated for nitrification and to enhance the growth of nitrifying bacteria. The parallel treatment zones combine and pass into a final denitrification zone. Phosphorus removal is achieved with phosphate release in a reverse flow regime to the main treatment, and phosphate retention primarily in aerated treatment zones in the main stream of the process.

Abstract: A wear disk for a crimping machine used in the manufacture of synthetic fibers comprises a sinter material of metal and carbon having an apparent density of from 4 to 7 g/cm.sup.3. The metal of the sinter material is particularly copper or an alloy thereof and therefore highly heat conductive.

Abstract: An auxiliary combustion air supply arrangement for an internal combustion engine having a combustion air supercharger driven by an exhaust gas turbine. During time periods characterized by lack of sufficient exhaust gas energy, in order to increase the supply of air to the intake manifold of the engine, auxiliary combustion air is obtained directly from a compressed air tank and is supplied to the intake manifold via an appropriate control mechanism. A delay element as part of the fuel injection system is provided, whereby the control mechanism as well as the delay element are actuated by operation of a gas pedal, as a result of which the supply of auxiliary combustion air precedes the fuel injection, with injection of the full fuel injection quantity not being initiated until later.

Abstract: A process for filtering a liquid through a combination of a first sieve, a sand pack and a second sieve in the direction of flow of the liquid, is described. This process differs from the known process in that the liquid passes through a filter pack in which the mesh width of the first sieve is at most equal to the mesh width of the second sieve, and the mesh width of the second sieve is smaller than the smallest particle size of the sand in the sand pack. Furthermore, the mesh width of the second sieve is at most 80 microns.When using this process uniform filaments without variations in titer from filament to filament or over the length of a filament are obtained. The rise in pressure relating to time is very small.
