Patent ES-420430-A1 (ES)
Title: Magneto ignition system for internal combustion engines
IPC: H02K21/48
Filed: 1973-11-10
Abstract: In a magneto ignition system where the magneto generator has two windings with a different number of turns, a diode is connected between the winding with the larger number of turns and the capacitor, the discharge of which through the spark coil generates the ignition voltage. The two windings are excited in phase. A second diode is connected between the two windings in such a way that when there is a positive voltage half-wave of the polarity which causes the first diode to conduct, the second diode is blocked so long as the winding with the larger number of turns has a voltage exceeding that across the winding with the smaller number of turns. At higher speeds the second diode conducts, thus preventing the capacitor voltage at ignition time from dropping with increasing speed. During voltage half-waves of the opposite polarity, when both windings are unloaded, the second diode conducts at whatever the speed the engine is running, reducing the peak voltage by the equalizing current that flows and thus protects the first diode against the possibility of excessive back voltage.

Title: Continuous casting of a metallic product by electromagnetic centrifuging
IPC: B22D27/02
Filed: 1977-01-20
Abstract: A metallic product is cast continuously by injecting a liquid metal into a cooled ingot mold, applying a magnetic field turning about the axis of the mold to rotate the metal, and extracting the partially solidified metal product from the mold.

Title: Steering valve arrangement for vehicles
IPC: B62D5/083
Filed: 1979-09-03
Abstract: A steering valve arrangement for a hydraulically operated steering system of a vehicle has two spring-loaded, seated inlet valves 10a and 10b. In such arrangement the supply from a pressure medium source 2 to a respective working chamber 12a 12b of an adjusting motor 14 is closed in the neutral position of the steering system. The springs 25a, 25b of the seated valves 10a, 10b counteract the force which is generated by the drop of pressure respectively occurring at the seated valves. The arrangement includes two rotary members 22, 23 arranged coaxially one within the other and rotatable in relation to one another upon a steering movement being effected. Upon such steering movement being effected in one direction or the other, the rotary members 22, 23 reduce the force of the valve spring of the seated valve. A centring spring, in the form of a torsion rod 27 is operative between the rotary members 22, 23. In order to obtain a comparatively flat rise in the steering force-pressure characteristic on both sides of the neutral position, there is so connected to the valve spring and in opposition to it, a further spring (fine control spring) that upon a steering movement the rotary members first act on both springs and act directly on the valve spring when the travel of the fine control spring has been used up. The rotary members 22, 23 are constructed as components of a rotary slide valve which forms adjusting throttles 16a, 16b for the working fluid flowing back out of the adjusting motor 14.

Title: Temperature indicator for showing the temperature condition of a ceramic cooking surface.
IPC: H05B1/02
Filed: 1980-10-30
Abstract: The temperature indicator has a temperature sensor which operates a switch. The temperature sensor is exposed to the heat of both the heating system of the glass ceramic cooking surface and an auxiliary heating system.
