Abstract: A thread cutting insert for cutting threads includes a plurality of cutting teeth disposed along a cutting portion, each cutting tooth is provided with an allocated chip former, and the chip formers are provided on a rake face of the thread cutting insert. The shape of at least two cutting teeth is different from each other. At least one cutting tooth along the cutting portion is provided with an allocated chip former the shape of which is adapted to the shape of that cutting tooth which, with respect to an order of engagement during cutting operation, precedes the subsequent cutting tooth along the cutting portion such that the at least one chip former has a shape adapted to the cross-section of chips encountered by it. A set of at least two thread cutting inserts, a thread cutting tool and a method for cutting threads, are also provided.

Abstract: For transferring signals relative to an electric machine provided with a three-phase power supply cable with three phase conductors, there is applied a signal to be transmitted to a first point in the three-phase cable between anyone of the phase conductors of such cable and both of the other phase conductors taken conjointly, and a reception signal is picked up in another point in said cable between anyone of the phase conductors of such cable and both of the other phase conductors taken conjointly.Preferably, similar capacitors are associated with each of the phase conductors in the cable at each end thereof, a galvanic separation transformer being disposed between such conductors, and the transmitter and the receiver, respectively, and an inductance being disposed between such transformers and conductors.
