PERFECCIONAMIENTOS EN UN DISPOSITIVO PARA LA TRANSMISION DE SENALES EN UNA MAQUINA TEXTIL ACCIONADA A MOTOR.

摘要

Apparatus for transmitting signals between a fixed station to a mobile station in a power driven textile machine, e.g. a bale opener for textile fiber bales wherein the bale opener including a movable delivery member. The fixed station includes a transmitter and a receiver and the mobile station includes a transmitter and a receiver with each transmitter being disposed opposite a receiver of the other station. The transmitter includes a clock pulse generator which feeds a counter at whose output a plurality of bits are formed for addresses, with these bits being fed to a multiplexer. In dependence on the address bits, a certain data input is selected at the multiplexer so that an electrical connection is established between the selected data input and a release or gate unit which releases the address at the output of the counter to a transmitting encoder if a signal is present at the selected data input. The receiver includes a clock pulse generator which feeds a counter at whose outputs a plurality of bits are formed for addresses. These address bits are fed both to a receiving decoder and to a demultiplexer and an electrical connection is established between the receiving decoder and a release unit if the received transmitted data coincides with the address formed by the counter of the receiver so that an actuating signal for a certain output is formed in the demultiplexer.
