Patent ES-8407278-A1 (ES)
Title: Signal sampling circuit
IPC: H04N9/72
Filed: 1983-10-21
Abstract: A signal clamping and sampling circuit wherein signals to be sampled are applied to a voltage amplifier (52). The output of the voltage amplifier is coupled in common to the inputs of first (53) and second (57) matched operational transconductance amplifiers (OTA's). During an initial clamping reference interval, the first (53) OTA conducts to form a feedback clamping network for establishing input and output reference bias conditions for the voltage amplifier. The second (57) OTA conducts during a subsequent sampling interval for processing signals to be sampled. The output reference bias of the voltage amplifier determines substantially identical input bias conditions for both the first and second OTA's, thereby significantly reducing the likelihood of signal processing offset errors being produced as between the clamping and sampling intervals when the first and second OTA's are respectively conductive. A level shifting network may be used for applying the signals to the voltage amplifier for providing signals compatible with the input requirements of the amplifier.

Title: Removal of impurities from molten aluminium.
IPC: C22B21/06
Filed: 1983-11-15
Abstract: Ti and V impurities are removed from molten aluminium by adding a boron-bearing substance and agitating the aluminium in the presence of a dispersed chloride and/or fluoride flux active for fluxing (Ti,V)B2 particles.

Patent ES-8607515-A1 (ES)
Title: Process for mechanical power generation
IPC: F01K25/06
Filed: 1985-01-10
Abstract: A process of mechanical power generation including a binary cycle whose primary cycle works with a mixture of water and another substance of much lower volatility substantially immiscible with water. In the primary cycle, at least part of the vaporization of the water is accomplished by means of the heat yielded simultaneously by condensation at variable temperature of the substance of high boiling point. This binary cycle allows obtaining much higher efficiencies than conventional cycles in small power plants (up to 50 MWe), thanks to the diminishing energy losses in the heat absorption, optmising the expansion efficiencies with simple turbines and substantially eliminating the vacuum in the installation. The proposed cycle has better partial load efficiency and lower response time than conventional cycles, with similar cost.
