Title: Improvements in electrolytic reduction cells.
IPC: C25C3/08
Filed: 1982-06-25
Abstract: In an electrolytic reduction cell in which molten metal is produced by electrolysis of a molten electrolyte, less dense than the molten metal product, the molten product metal collects at the bottom of the cell.

Title: Process for the control of the welding time of an electrical welded union
IPC: G05B13/00
Filed: 1984-11-30
Abstract: Two tubes of thermo-plastic material are joined by a sleeve in an inner portion of which there is an electrical resistance coil, the ends of which are connected to terminals projecting from the outer surface of the sleeve. An electrical circuit supplies electric current to the coil to heat an inner weld zone to welding temperature, while leaving enveloping outer portions at lower temperature. In the sleeve there is provided a radial hole or recess into which the heated material expands upon reaching welding temperature. The material expanding into the hole or recess when welding temperature is reached is sensed by a pressure responsive micro-switch or electro-optically by an optical transmitter and receiver and through a control circuit, shuts off the power to the resistance coil. The parts being thereby fused together, are allowed to cool to complete the weld.

Title: Method and system for interconnecting synchronous or asynchronous three-phase networks by means of variable reative impedances.
IPC: H02J3/24

Abstract: A method and a system for interconnecting two electrical, alternating three phase networks operating asynchronously or synchronously at voltages of equal or adjacent frequencies, and in which, for corresponding phases, the voltages of the first and second networks are out of phase by a constant or varying angle. A plurality of three phase variable reactive impedances interconnect the two networks for carrying out a desired transfer of active power from one of the two networks to the other.

A regulator measures electrical parameters associated with at least one corresponding phase of the first and second networks, and operates the three phase variable reactive impedances to vary the susceptances of the interconnections in relation with the measured parameters so as to establish the desired transfer of active power from one of the first and second networks to the other network, while maintaining at a desired level a reactive power engaged in the transfer of active power.
