Patent ES-486470-A1 (ES)
Title: Sequential ignition and extinction for gas burners - uses circuit with sawtooth versus variable threshold comparison to operate gas valve and spark ignition for safe low temp. cooking
IPC: F23N5/20
Filed: 1979-11-29
Abstract: The system uses alternate flame on/flame off periods in which the gas supply is automatically turned on or off with automatic spark ignition. A rectified supply drives a ramp generator which, in conjunction with a voltage comparator generates a saw tooth voltage wave form at an input of a second comparator where the sawtooth is compared against a DC threshold level set by the operator. When the sawtooth crosses the threshold a thyristor circuit operates a valve to supply gas to the burner, the gas being ignited by a spark plug. The spark generator is triggered by the same signal as operates the gas valve. When the sawtooth waveform returns across the threshold the gas is turned off. The relative ON/OFF times are determined by the threshold level in relation to the sawtooth waveform.

Patent ES-8300141-A1 (ES)
Title: A method for manufacturing metal from fine-grain metal-oxide material
IPC: C22B1/00
Filed: 1981-11-06
Abstract: Metal is produced from fine-grain iron-containing metal oxide material. In a first reduction stage the oxide material is at least partially reduced in a fluidized state at a temperature of approximately 1025 - 1275 K, using a reduction gas containing carbonmonoxide, optionally in mixture with hydrogen. In a following smelting and final-reduction stage there is formed a metal melt, whereat the reducting gas used for the first reduction stage is obtained from the smelting and final-reduction stage. Prior to the first reduction stage, relatively large cakes or shaped pieces are formed from the fine-grain metal-oxide material in the presence of moisture and a hydraulic binder, whereafter said cakes or pieces are caused to harden. The hardened oxide material is disintegrated and classified to form the starting material for the first reduction stage, and is given a particle size distribution such that the material forms a fluidized bed which is substantially stationary at the considerable gas velocity required to carry out the reduction process without bogging at the temperature selected for the first reduction stage.

Title: Radio communications apparatus.
IPC: H04K1/00
Filed: 1982-06-18
Abstract: Channel selection in a frequency hopping radio set is controlled by a pseudo-random number generator, the pseudo-random number being used to address an N bit memory (3) which is used to identify each of n available channels from N equipped channels.

Patent ES-8402682-A1 (ES)
Title: Fail-safe timing circuit.
IPC: H03K17/60
Filed: 1983-03-14
Abstract: A total security time-delay circuit useful in railway communications, for example, provides a series of output pulses after a specific minimum interval in response to a direct voltage applied to an input of the circuit, the minimum interval being maintained even in the event of circuit component malfunctions. A pulse generator connected to the circuit input provides a series of pulses to control a first contact breaker which switches the primary winding of a transformer to partially discharge a capacitor which is series-connected to the primary winding. The capacitor charges through a resistive network of a transformer secondary winding circuit which includes a second contact breaker having a control terminal connected to the transformer secondary winding and operable to provide output pulses when the capacitor discharge reaches a sufficient intensity. A grounded Zener diode connected to a junction of the resistive network and a switch terminal of the second contact breaker ensures that the time delay of the output pulses is not reduced below the minimum interval, even in the event of malfunctions in other circuit components.
