Abstract: The present invention provides a process for surface finishing sheets made from thermoplastics by applying a partially fused layer of thermoplastic polyurethane.

Abstract: Composite moldings of at least one layer of an ABS plastic and at least one layer of a thermoplastic polyurethane having a Shore D hardness of >50, a layer of coupling agent optionally being present between the ABS layer and the thermoplastic polyurethane layer.

Abstract: For the transmission of data signal bits occurring with a first bit rate from a transmission device by way of a transmission link to a receiving device in a bit stream having a second bit rate which is higher in comparison to the first bit rate, the data signal that is to be transmitted are combined in the transmission device with additional filler bits to form envelopes respectively comprising a prescribed plurality of bits, this being executed given non-transgression of the prescribed bit rate difference between the first bit rate and the second bit rate. The envelopes are transmitted via the transmission link with the second bit rate. Given transgression of the prescribed bit rate difference, the data signal bits, with first bit groups identifying the same as belonging to data signal envelopes, are combined with bits of separate envelopes which respectively contain a second bit group identifying them as blank envelopes and are transmitted via the transmission link with the second bit rate.

Abstract: An apparatus for connecting a selected one of two teleprinters to a common communication line includes a control unit associated with each teleprinter and an analysis circuit connected to both control units and to the common line through a line interface unit. The analysis circuit can sense an incoming teleprinter selection code and connect the selected teleprinter to the common line. Alternately, the analysis circuit can sense a teleprinter originated communication and connect that teleprinter to the communication line.
