摘要:
Described is a radiation-crosslinkable hotmelt adhesive comprising at least one radiation-crosslinkable poly(meth)acrylate formed to an extent of at least 60% by weight of C1 to C10 alkyl(meth)acrylates and at least one oligo(meth)acrylate which comprises nonacrylic C C double bonds and has a K value of less than or equal to 20. The hotmelt adhesive comprises a photoinitiator which may be present in the form of an additive not attached to the poly(meth)acrylate and/or not attached to the oligo(meth)acrylate, may be incorporated by copolymerization into the poly(meth)acrylate, and/or may be attached to the oligo(meth)acrylate. The hotmelt adhesive can be used for producing adhesive tapes.

摘要:
A description is given of a pressure-sensitive adhesive dispersion comprising a water-dispersed polymer P1 formed by emulsion polymerization. The polymer P1 is formed from a monomer mixture comprising (a) at least 40% by weight of C4 to C20 alkyl (meth)acrylates which when polymerized as homopolymers have a glass transition temperature of −30° C. or less, (b) at least 0.05% by weight of (meth)acrylate monomers having a substituent of the formula where X is CH2, O, NH or NR and R is a C1 to C4 alkyl group, (c) at least 0.1% by weight of acid monomers. The polymer P1 is prepared by polymerization in at least 2 stages, the glass transition temperature of a polymer from monomers of the first stage being lower by at least 20° C. than the glass transition temperature of a polymer from monomers of a later, second stage.

摘要:
A superstructure device (10) for a set of points having a switch support which is composed of a block of high-strength steel and which has stock and short point rails which delimit said switch support and are formed integrally from the block, wherein the block is connected to a lower part composed of a material other than the high-strength steel, such as mild steel, and is in particular connected in a materially joined fashion, wherein the block extends essentially over the entire length of a switch rail device as the superstructure device on both sides beyond the switch support, and the lower part is a means of supporting the block in the form of at least two supports which are spaced apart from one another.
摘要:
A method of path planning for a working resource to access storage bins in a warehouse, the warehouse comprising a plurality of storage bins, the warehouse being divided into a set of activity areas, each activity area comprising a number of the bins of the warehouse; the method comprising the following steps: Selecting one out of a set of activities of a working resource in the warehouse; selecting a sort sequence which is associated with the selected activity, the sort sequence defining a path through the activity area the working resource has to follow when accessing the bins; determining, based on the selected activity area and the selected sort sequence, the path through the activity area to the bins.
摘要:
A method and controller are provided for controlling a power train of a vehicle having a number of modes of operation. A first controller is provided for controlling of a first function of the vehicle. At least one second controller is provided for controlling of a second function of the vehicle. The first controller and the at least one second controller are combined in a joint controller having a state observer and a number of controlling entities. The joint controller is operated by a set of formal controlling parameters assigned to the controlling entities. Actual parameters of the set of formal controlling parameters are switched according to a current mode of the number of modes of operation.
摘要:
A system for operating an hybrid vehicle is described. The system includes an hybrid operating strategy module for controlling hybrid operating functions of the vehicle based on input data, a navigation system providing vehicle routing input data to the hybrid operating strategy module, and a traffic information system providing traffic information input data to the hybrid operating strategy module. The hybrid operating strategy module determines electric portions of the vehicle route for charging batteries of the vehicle and inner portions of the vehicle route for prioritizing electric driving.
摘要:
A method is provided for extending the useful life of a rechargeable energy storage unit for use in a motor vehicle, such as, in particular, a double layer capacitor, a lithium ion storage unit, a lithium ion capacitor or a NiMH storage unit, which exhibits a plurality of storage cells. In order to extend the useful life of the energy storage unit, it is proposed that the temperature and/or storage capacity of each of the storage cells be measured. If the temperature of a storage cell exceeds a reference value for the temperature of the storage cell on the storage cell is partially discharged, and, in this way, its voltage is reduced.
