Abstract: An improved method for the preparation of melamine by the conversion of urea and/or thermal decomposition products thereof. The urea and/or thermal decomposition products are converted to melamine in the presence of a gas mixture containing ammonia and carbon dioxide in a reaction zone containing a fluidized bed of catalytically active material. Melamine is desublimated from the melamine containing gas mixture in a desublimation zone by a dry-capture method leaving a desublimator off-gas mixture of ammonia, carbon dioxide and gaseous impurities. A major portion of this desublimator off-gas mixture is compressed and recirculated to the reaction zone as fluidizing gas for the bed of catalytically active material, without intervening treatment to remove gaseous impurities from the desublimator off-gas.

Abstract: Due to a control engineering context, write and read pulse frames of time-slot multiplexers of different switching matrix stages in a multi-stage, time-division multiplex switching matrix network exhibit coinciding pulse frame boundaries. In deviation therefrom, pulse frame boundaries of the pulse frames on switching network internal time-division multiplex lines are offset due to delays that are caused by serial-to-parallel and parallel-to-serial conversions of a partial information upon their intermediate storage in the time-slot multiplexer. Of two complete memories per time-slot multiplexer, one part of the one memory and another part of the other memory are inscribed during the pulse frame of an incoming time-division multiplex line. Auxiliary information is derived from an address (corresponding to the outgoing time channel) serving for the selection of a holding memory and form an address (corresponding to the incoming time channel) assigned for reasons of switching engineering and serving for the selection of a complete memory, the auxiliary information indicating from which of the complete memories the information to be forwarded is to be read so that, given multi-channel connection, the required sequence of the partial information is assured.

Abstract: The single power conductor carries audio and a serial data bus. The microphone's amplifier (101) is connected to the conductor (108). The incoming audio signal rides on the DC supply voltage from the radiotelephone. The supply voltage, through a voltage regulator (103), supplies power to the amplifier (102) and a microprocessor (105), used to transmit the serial data message on the conductor (108). Both the amplifier (102) and the voltage regulator (103) are isolated from the power conductor (108) by a FET switch (104) that is controlled by the microprocessor (105). The switch (104) is turned off, isolating the circuitry when the microprocessor (105) is transmitting. <IMAGE>
