Abstract: For each channel, a pair of buffers permits "non-slip" transfer of data signals on and off a bus synchronized with signals on a time-division multiplexed pulse-code modulation (PCM) highway. A source buffer consisting of a serial-in, parallel-out register and two parallel-in, parallel-out registers receives signals from one of the PCM channels and transmits these signals onto a bus synchronized with a data-routing multiplexer employed within a digital exchange controller employing the device. A destination buffer consisting of two parallel-in, parallel-out registers and a parallel-in, serial-out register receives signal from the bus and, in conjunction with a transmit multiplexer, generates the signals on the PCM highway.

Abstract: Highly sensitive methods for assaying for biopolymers, such as by immunoassay or nucleic acid probe hybridization assay, and compositions for carrying out the methods, are provided. The methods employ as reporter group a RNA capable of being autocatalytically replicated by an RNA-dependent RNA polymerase, such as the replicase of bacteriophage Q beta . The high sensitivity of the assay methods is due to the rapid, exponential increase in concentration of such a replicative RNA, associated specifically with biopolymer analyte, that can be achieved by autocatalytic RNA replication.
