Patent ES-453496-A1 (ES)
Title: Electrical polarity switch for battery
IPC: H02H11/00
Filed: 1976-11-19
Abstract: A switch including an input terminal which is electrically connected in use to one pole of an electric storage battery, an output terminal and a movable contact movable between an inoperative position wherein the movable contact is isolated from at least one of the input and output terminals and a operative position wherein the movable contact electrically interconnects the input and output terminals. An electro-magnet winding is provided which, when energized prevents movement of the movable contact to the operative position and the winding and a semi-conductor diode are connected in series between the input terminal and a further terminal which in use is connected to the other pole of the battery. The diode is so orientated with respect to the intended battery connection polarity that the diode conducts to energize the winding and so prevent movement of the movable contact to its operative position, in the event that reversed polarity connections are made between the battery and the input and further terminals.

Patent ES-455230-A1 (ES)
Title: Refractory structures for outlet valves for metallurgical vessels
IPC: B22D/
Filed: 1977-01-21
Abstract: In this method, the pressure head (56) of molten metal (2) is measured continuously, via a bottom opening (3) in a tank (1), by weighing. The measured values are used to produce pulses, the frequency of which is proportional to their square root, with the result that the frequency is proportional to the outflow rate. The pulses are counted. When a predetermined count has been reached, the bottom opening (3) is closed by means of a plug (4). The riser level of the filled mould is measured during the pouring of the next mould and, if deviations from a predetermined level are detected, the predetermined count for the filling of the subsequent moulds is corrected. This method allows short cycle times and precise metering of the quantity of metal. It is, in particular, suitable for the filling of casting moulds having a top runner.

Patent ES-8403651-A1 (ES)
Title: Spectral shift reactor.
IPC: G21C7/26
Filed: 1981-12-14
Abstract: A mechanical spectral shift reactor for controlling a nuclear reactor with a plurality of reactor coolant displacer members (40) which are inserted into a reactor core (34) at the beginning of the core life. The displacer members reduce the volume of reactor coolant-moderator in the core (34) at start-up. However, as the reactivity of the core (34) declines with fuel depletion, selected displacer members (40) are withdrawn from the core (34) at selected time intervals. The withdrawal of the displacer member allows reactor coolant to enter the core (34) which increases core moderation at a time when fuel reactivity is declining. Thus for a given amount of nuclear fuel the life of the core can be extended or for a given life of a core the uranium fuel requirements can be reduced.
