摘要

Improvements in the electrical circuits of the mechanisms for warps, consisting essentially of having an electromagnetic relay, which governed by electronic tube or amplifier, acts together on two switches, one of which works on the circuit of the stop mechanism and the other on a self-powered circuit of the relay itself, whose circuit has, in turn, a trip switch that cuts off the self-supply in the stop position, also figuring, mounted in parallel with the aforementioned relay, a filter cell to stabilize the current, as well as an input transformer for the different working voltages of the system.
