Patent ES-385377-A1 (ES)
Title: Receivers for phase comparison radio navigation systems
IPC: G01S5/10
Filed: 1970-11-09
Abstract: In a receiver for a phase comparison radio navigation system in which fixed stations normally radiate signals, one from each station on different harmonics of a common fundamental frequency and in which, for lane identification, each station periodically radiates simultaneously signals of a number of frequencies, known as a multipulse, from which a signal of the fundamental frequency may be derived at the receiver, the receiver has an oscillator locked in phase to signals of the one frequency normally radiated from the master station. The output of this oscillator is divided down to the fundamental frequency but the divider is not notched. Instead the phase relationship between the fundamental frequency signal from the master multipulse transmissions and the divider output signal are compared digitally in phase and the phase difference is stored as a digital number and applied as a correction to all the phase determinations between the divider output and the fundamental frequency signals derived from the slave stations. This corrects not only for the absence of notching in the divider but also for certain other minor phase errors in the system.

Title: Electrolytic refining of silver
IPC: C25C1/20
Filed: 1975-09-22
Abstract: Silver is purified which contains copper as a significant impurity. In this process the electrolyte contaminated with copper is drawn off from the electrolytic silver purification cell and treated with an immiscible liquid phase which contains a selective complexing agent for copper ions. As a result, copper is removed from this electrolyte without the silver first having been removed. The electrolyte which after this treatment has a reduced copper content can again be used in the electrolysis for the purification of silver. It is possible to carry out continuously this process of drawing off, treatment and returning, so that the silver electrolysis takes place from an electrolyte which has an essentially constant copper content.
