  • Publication number: 20170226370
    Abstract: The present invention encompasses a novel soil-repellent reactive resin seal for markings or coating of areas of ground or trafficways, for example roads, based on cold plastic. Compared to established prior art systems, this sealing leads to reduced adhesion of soil, especially in hot and/or dry, dusty environments. Thus, the marking retains better visibility than conventional markings, even in dry, hot regions. Otherwise, the marking sealed in accordance with the invention has comparable mechanical properties to the prior art.

  • Publication number: 20160312384
    Abstract: A method of making a spun-bond nonwoven fabric of thermoplastic filaments has the steps of first spinning the thermoplastic filaments, then cooling the spun filaments, and then conducting the cooled and spun filaments in a travel direction through a stretcher with primary air such that the primary air exits a downstream end of the stretcher with the filaments at a predetermined primary air volume/flow VP. The filaments and substantially all of the primary air are passed together as a flow from the downstream end of the stretcher into a diffuser. Secondary air is introduced into the flow at a secondary air volume/flow VS such that a ratio VP/VS of the primary rate VP to the secondary rate is equal to at least 4.5 and the primary and secondary air flow with the filaments in the travel direction through the diffuser.

  • Publication number: 20160222558
    Abstract: A nonwoven web made of plastic fibers and having a web thickness less than 2 mm (preferably less than 1.5 mm) and a grammage less than 30 g/m2 (preferably less than 25 g/m2) and conveyed this web in a travel direction so that it physically contacts a guide or treatment roller. A stabilization plate extending in and transversely to the travel direction of the nonwoven web is provided upstream or downstream of the roller in the travel direction, and the nonwoven web is guided in the travel direction past the stabilization plate such that a spacing between a face of the stabilization plate turned toward the nonwoven web and the nonwoven web face is 0 to 20 mm (preferably 0.1 to 10 mm, and very preferably 0.2 to 5 mm).

  • Patent number: 9366220
    Abstract: In a power tool, an internal combustion engine is coupled by a clutch to a tool member. An ignition control device is provided that for each engine speed of the internal combustion engine specifies at least one ignition timing. For each engine speed of a first engine speed range a correlated first ignition timing is specified, wherein each first ignition timing is an ignition timing of a first ignition timing range. For each engine speed of a second engine speed range, adjoining the first engine speed range, a correlated second ignition timing is specified, wherein each second ignition timing is an ignition timing of a second ignition timing range. The first ignition timing is retarded by at least 5° crank angle relative to the second ignition timing. The first engine speed range extends at least from the coupling engine speed range to the limit engine speed of approximately 7,000 RPM.

  • Publication number: 20150299921
    Abstract: An apparatus for the continuous manufacture of a spunbond web from aerodynamically stretched thermoplastic filaments has at least one spinneret, a cooling chamber for cooling the filaments, a stretcher, and a deposition device for the deposition of the filaments to form the spunbond web. At least one filament guide having a plurality of filament-guide gaps opens toward the stretcher between the stretcher and the deposition device, and the filament guide or at least one guide part of the filament guide can be moved such that the filament-guide gap or the stretcher-side openings thereof are displaced transversely to the travel direction of the spunbond web. Thus the filaments or filament bundles guided along or through the filament-guide gap are given a transverse orientation to the travel direction of the spunbond web when deposited onto the deposition device.

  • Publication number: 20150101578
    Abstract: A method of estimating a boost pressure of a turbocharger is disclosed. A throttle body temperature is estimated as a function of engine operating parameters. An intake air mass flow and an exhaust mass flow are estimated as a function of the throttle body temperature. A turbine inlet pressure and a turbine outlet pressure are estimated as a function of engine operating parameters. A turbine speed is estimated as a function of the intake air mass flow, exhaust mass flow and turbine inlet and outlet pressure. The boost pressure is estimated as a function of the turbine speed. Estimation of the maximum boost pressure of a turbocharged internal combustion engine is performed method cyclically as follows: estimating a throttle temperature, estimating an air mass flow and an exhaust mass flow, estimating a turbine inlet pressure and a turbine outlet pressure, estimating a turbine speed, and estimating the maximum boost pressure.

  • Publication number: 20140128536
    Abstract: The present invention relates to an innovative (meth)acrylic reactive resin which cures with low odour or odourlessly. The present invention relates more particularly to reactive resins comprising high-boiling, reactive (meth)acrylic monomers from the group of the polar, cyclically substituted esters of (meth)acrylic acid, more particularly glycerol acetal, ketal or carbonate methacrylates. These new components are used as substitutes for MMA, which represents the major part of the odour nuisance in the existing, prior-art reactive resin systems. Using these new components it is possible to obtain resin formulations which have glass transition temperatures similar to, and properties comparable with, MMA-based resins. The innovative reactive resins are able in addition to exhibit more rapid curing than prior-art MMA-based systems. Reactive resins for the purposes of the invention are reactive monomer mixtures or mixtures of monomers and polymers that when used as a 2-component system can be readily cured.
