Patent ES-452880-A1 (ES)
Title: Static inverter with controlled core saturation
IPC: H02M7/53846
Filed: 1976-10-29
Abstract: A static inverter is disclosed for d.c. to a.c. conversion comprising a pair of switching semiconductor devices and a power transformer having primary, secondary and control windings associated with a double apertured linear magnetic core. Each aperture partitions the core cross section in a localized region into two branches. The primary and secondary power windings encircle the full core, which has a closed magnetic path, while the control windings are associated with only a branch. Means are provided to cause one branch to saturate before the other branch and before full core saturation. Saturation of one branch is used to reduce the regenerative feedback and increase the degenerative feedback to provide an advance turn off, allowing charge stored in the switching device to dissipate prior to the end of each conduction period. This mode of the feedback control avoids full core saturation and avoids overstressing the switching devices that full core saturation would produce. The arrangement permits one to develop high power outputs from relatively inexpensive power transistors.

Title: Manufacture of fibres by means of gaseous currents with economy of energy
IPC: C03B37/06
Filed: 1978-08-23
Abstract: The process of manufacture of fibres from a mineral thermoplastic substance employs a main gas stream (27) and a secondary gas jet (29). The section of the secondary jet is smaller than that of the main stream but the kinetic energy per unit volume of the secondary jet is higher than that of the main stream. The secondary jet is directed transversely to the main stream and enters it to create a zone of interaction (Z) which includes turbulent streams. A lace of ductile substance (34) is brought into this zone by the secondary jet. In the interaction zone the streams of gas contain oxidising fuel components introduced from the duct (35) by the nozzle (36) in proportions which result in a combustible mixture. The lace of ductile substance is brought into the zone (Z) at a temperature which is at least equal to the ignition temperature of the mixture. The process is employed especially for making fibres from glass.

Title: Process of producing sulfuric acid
IPC: C01B17/765
Filed: 1979-11-30
Abstract: A process for the production of sulfuric acid from wet sulfur dioxide containing gases is disclosed.
