Title: Error detecting system for data packets - counts bits in each received packet and compares these with required number
Inventor: DZAMKO OLEG DIPL ING
IPC: B61L3/00
Filed: 1980-02-19
Abstract: The error detector has each data packet provided with a redundant bit of given value. The bit is sent as the first bit after the start signal. Each bit in a packet arriving at the receiver causes a resettable counter to count forwards by a value of one. The received bits are stored in a memory having as many places as there are bits in a packet. The places are set to the value opposite that of the redundant bit. All bits in the memory are moved on to the next place in the memory by the arrival of the next bit. As soon as the value of the last place in the memory changes, the contents are compared with a given value equal to the number of bits in a packet. If the two numbers are not equal, an error signal is released. Used in digital line transmission in railway train.

Inventor: GOLDIN RODION GRIGORIEVITSCH
IPC: H02P9/14
Filed: 1980-03-10
Abstract: The installation contains an excitation device (1), which is connected to the excitation winding, and a starting and protection apparatus (9), which responds to overvoltages of both polarities and has a plurality of parallel paths (strands) (11, 12, 13) with a resistor (15) and thyristor switches (16) connected in reverse-parallel, between the anode and control electrode of which thyristor switches (16) a first threshold-value element (20) is connected. A triggering circuit (14) contains a second threshold-value element (23) whose response voltage level is lower than that of the first threshold-value element, a storage unit (26) which can be switched on by the second threshold-value element (23), and a pulse-forming element (27) which can be triggered by the storage unit (26). This pulse-forming element is connected to the control electrodes of the thyristor switches (16) such that a voltage pulse switches the thyristors in the other parallel paths on once the current relay has responded as a consequence of the current flow through one parallel path (11, 12, 13). In consequence, the response reliability and operating reliability are increased and all the parallel paths are switched on only in the event of overvoltages on the excitation winding in the transition modes. <IMAGE>
