Patent FR-2258913-A1 (FR)
Title: Forming rollers for cylindrical component - progressive undercut on inclined sides of forming wedge
IPC: B21H1/18
Filed: 1974-01-24
Abstract: When a cylindrical component with reduced diameter over its central section is produced by forming rollers, a considerable tensile force is set up by the tapered sides of the forming wedges. Since this tensile force is a function of the taper angle and the diameter reduction ratio, it is a limiting factor on roller forming. By progressively undercutting the tapered sides, starting with no undercut at the thin end of the forming wedge, the tensile force set up decreases from a maximum at the beginning of the forming process to zero at the end of it. This leads to an improved diameter reduction ratio and thus a higher rolling efficiency.

Title: Self-commutating static inverter cct. - has common storage capacitor for commutating thyristors for all three phases
IPC: H02M7/515
Filed: 1974-09-23
Abstract: The self-commutating static inverter has two series-coupled thyristors per phase connected between the d.c. supply oppositely poled terminals. Each thyristor is bridged by an anti-parallel diode. The thyristors are commutated by the energy stored in a capacitor common to two phases. For static inverters with centre-tapped d.c. supplies the capacitive store aiding commutation consists of a single capacitor common to all phases and connected to the d.c. supply centre tapping. The thyristors are each connected over current limiting inductors to their respective d.c. terminal and, in the case of the centre-tapped supply, the capacitor may be connected over a current-limiting inductor to that centre point.

Title: Ferromagnetic thin film magnetometer - has plated wire detection element which is fitted with excitation coil, differential detection circuit and feedback loop
IPC: G01R33/05
Filed: 1974-10-03
Abstract: The thin-film magnetometer uses a magnetic vector rotation mechanism. It comprises an orthogonal detection element having a plated wire (4) with a thin film (5) ferromagnetic cladding surrounded by a detection coil (7). An alternating electrical source of excitation is connected to the input (12) of the magnetic detection element and thus excites the thin film material (5). An amplitude difference detection circuit (17) is connected to the output of the detection element and produces a signal which indicates the difference between positive and negative voltage peaks. This output signal is returned to the detection coil through a feedback circuit whose operation is controlled by a control circuit. The feedback current annuals the external magnetic field applied to the detection (22) element and thus gives a measure of this field.
