The quantity and color of the fractions of each component as selected so that the mixed color resulting from an homogeneous intermixing of all the components contained in the floor covering agrees with the first color.

Abstract: A method for improving the adhesion of an elastomeric, polymeric material to a support element while being shaped and vulcanized thereon, in which the support element is wetted in the region of the adhesion zone with a liquid composition of an adhesion promoter, the coating thus formed is solidified, and the elastomeric material is subsequently shaped on and solidified by vulcanization, an aqueous and/or alcohol solution of a thiocyanatosilane being used as the adhesion promoter.

Abstract: A dust filter bag made of a fiber layer laminated together with a paper layer. The fiber layer is made of synthetic polymer fibers and is arranged on the downstream side of the paper layer. To increase the strength of the dust filter bag, the fiber layer contains melted polymer regions and by way of the polymer regions the fiber layer is additionally consolidated within itself and joined to the paper layer. The polymer regions have a welded area of 0.5 to 10% of the surface area, preferably 1 to 3%, thus resulting in sufficient laminate strength with a low pressure drop.

Abstract: A method for manufacturing a filter insert, configured as a folding pack and made of thermoplastically bondable nonwoven material, such that a planar filter medium is first folded and then immobilized in a permanent form at a preset fold spacing by delivery of energy and subsequent cooling, such that after the process step of creating a defined fold spacing, the two outer edges of the folded pack are positively clamped into comb-like profiles, substantially corresponding to the fold geometry and dimensions of the folded pack and engaging in toothed fashion into the top and bottom of the folds, the spacing between which is chosen to be the same as or slightly less than the thickness of the nonwoven fiber fabric, wherein the folded filter material projects beyond the comb-like profiles at each outer edge a distance less than 1 times the fold spacing, wherein a sealing band, corresponding in width substantially to the height of the folds, is laid on the outer edges on the long sides, and in each case compressed

Abstract: A bearing arrangement for a vibrating component having a bearing supported on a carrier for the vibrating component and having a damper which interacts with the carrier and has an inertial mass that is movable relative to the carrier by a damper drive. The damper drive being provided with a drive circuit which includes at least one first sensing element of the vibrating component and a downstream signal generator which generates two harmonic, out-of-phase first signals, whose frequencies correspond to each other and to vibrations of a machine part, as well as a second signal characterizing this frequency. The second signal is supplied to characteristic curve elements whose output signals are multiplied by the first signals of the signal generator, and the third signals obtained in this manner are added up in pairs. The signals obtained in this manner each are multiplied by a fourth signal, generated by a second sensing element, characterizing the relative movements of the carrier.
