Abstract: A road-marking system comprising at least a first (1) and a second road marking unit (2), each having an emission surface (10; 20), the first unit comprising a first light source (21, 21? . . . ) and the second unit comprising a second light source (22, 22? . . . ). Each unit has a housing (11, 12) of a shape adapted to a saw-cut cavity (9) accommodating the unit and lying in a plane P. Each unit is provided with stabilizers (23, 23?; 24, 24?) which are situated at the ends of said emission surface and lie in the plane P as well, thus preventing turning of the unit around an axis A normal to the plane P.

Abstract: The invention relates to textile treatment compositions containing (K1) mixtures of (A) 0 to 30% by weight of polyalcohols obtained by catalyzed reaction of formaldehyde with ketones bearing at least 4 replaceable hydrogen atoms adjacent to the carbonyl group, (B) 0 to 30% by weight of polyalcohols other than (A), (C) 0.1 to 10% by weight of adducts of fatty acids, fatty alcohols, alkyl- or dialkylamines, or alkylphenols with 2 to 100 mol of ethylene oxide, and (D) 70 to 99.9% by weight of an aqueous softener formulation containing 10 to 90% by weight of softener compounds based on the aqueous softener formulation,  wherein the total amount of (A)+(B) is ≧0.1% by weight, based on the sum total of the individual components (A) to (D), and (K2) a bisulphite-blocked polyisocyanate prepolymer, wherein the weight ratio of component K1 to component K2 is 0.1:1 to 5:1.

Abstract: Known tags which are capable of receiving and demodulating signals by way of one and the same antenna and by way of one and the same diode, as well as being capable of modulating and transmitting signals, often have a poor efficiency, particularly if the antenna is implemented in the form of a flat plate. By coupling a high-ohm first terminal of the antenna to the diode, and coupling a low-ohm second terminal to earth by way of an inductive element, there is obtained a tag which has a good efficiency, both regarding the reception and demodulation of signals and regarding the modulation and transmission of signals.

Abstract: An admission device for admitting data cells having VC codes, to a transmission medium, includes a device for reading out the VC code of an arriving data cell, a device for comparing a count value, which is a measure of the load of the data cell with the read out VC code, with a threshold value selected by a sort code which is either derived from the arriving data cell, or has an external origin, such as a network-control system or network monitoring system located outside the admission device, and a device for thereafter issuing an admission code having a value which depends on the result of the comparison.
