The invention relates to a device for the pneumatic conveyance of bulk material, including a conveying pipe which defines a conveying path for the bulk material and in portions has a fluidizing pipe segment and a propellant gas source which is connected to the conveying pipe and is designed for the supply of propellant gas in the direction of the conveying path. The weighted mean arrival time is determined using path arrival times and energies from a Rake receiver. The data driver includes a precharging unit for selecting a specific precharge voltage from a plurality of precharge voltages applied to the data driver depending on grayscale sections of the input image data, and for precharging the selected precharge voltages to the respective data lines. Novel methods for producing synthetic leather articles using polymeric colorants are also provided. A first cushion cover covers the cushion core. One end of an extension member extends from a top of the hanger retaining member and the retaining rod extends from the other end of the extension member.
