Patent ES-470534-A1 (ES)
Title: Method of producing UO2 wherein methanol wash is provided
IPC: B01D3/10
Filed: 1978-06-06
Abstract: In the production of UO2, ammonium uranyl carbonate is an intermediate product wet with water and contaminated with ammonium carbonate and is washed with methanol to remove water and ammonium carbonate. The spent methanol containing 50% water and up to 10% ammonium carbonate is subjected to rectification in a column under subatmospheric pressure with cooling the top of the tower to a low temperature to retard decomposition of ammonium carbonate and condense a liquid water fraction. Clogging of the column, vapor lines and condenser by recombination of the decomposition products is prevented. The purified methanol contains less than 5% water and may be returned for further washing of ammonium uranyl carbonate.
Patent ES-473955-A1 (ES)
Title: Improvements in the control of electrically operated valves for turbo sprayers.
IPC: B05B/
Filed: 1978-10-04
Abstract: The improvements in question consist of controlling each of the electrically operated valves which govern the spray coverage and the pump discharge through independent switched circuits. These circuits determine the independent and selective activation from one electrically operated valve to another, whilst the combined activation of the electrically operated valve for spraying is performed through a relay. Each of the electrically operated valves for spraying, which operate independently and selectively, are activated through the corresponding switches, one for each electrically operated valve. The switches of the electrically operated valves for spraying are connected so that in the inoperative position they close a circuit which determines the idle state of the relay to supply the electrically operated valve for discharging the pump. When one of the switches of the electrically operated valves for spraying is activated, the other two electrically operated valves are deactivated and the relay is inactive. When the relay is activated, the two electrically operated valves for spraying are supplied, with the electrically activated valve for discharge remaining deactivated.

Title: Acoustic imaging system
IPC: G01S7/52
Filed: 1978-10-17
Abstract: An acoustic imaging system for displaying an object viewed by a moving array of transducers as the array is pivoted about a fixed point within a given plane. A plurality of transducers are fixedly positioned and equally spaced within a laterally extending array and operatively directed to transmit and receive acoustic signals along substantially parallel transmission paths. The transducers are sequentially activated along the array to transmit and receive acoustic signals according to a preestablished sequence. Means are provided for generating output voltages for each reception of an acoustic signal, corresponding to the coordinate position of the object viewed as the array is pivoted. Receptions from each of the transducers are presented on the same display at coordinates corresponding to the actual position of the object viewed to form a plane view of the object scanned.

IPC: B65B25/06
Filed: 1979-03-16
Abstract: A machine for automatically filling cans, especially flat cans with substantially rectangular contour, with goods of elongated configuration which, in a filling station, are manually laid into a horizontally continuous row of receptacles open at their adjacent ends and mounted on the links of an endless conveyor chain.

Patent ES-8106043-A1 (ES)
Title: Electro hydraulic servo valve
IPC: F15B13/044
Filed: 1980-10-08
Abstract: A solenoid operated valve is provided particularly constructed to decrease friction in the course of operation and thus of the hysteresis or actuating lag effect. The general construction utilizes a solenoid acting to maintain closure of a valve by pulling on an armature to which is integrally secured a valve operating element having a valve head at one end and which passes through the core on which the solenoid is mounted. The armature has a piston formation extending into a pressure chamber of the housing. Pressure in the outlet of the valve communicates with the pressure chamber to maintain a net closing effect on the valve. Accordingly, pressures at the valve are prevented from acting against the energized solenoid.
Patent ES-8301069-A1 (ES)
Title: Wire engagement and release arrangement
IPC: H01H1/58
Filed: 1980-12-02
Abstract: The present invention relates to a wire engagement and release arrangement for electrical switches, and the like, wherein the wire engagement arrangement consists of an electrical contact which is bifurcated to form two flat spring arms, one of which is shorter than the other. A pair of individual passageways through the housing of the device to be wired are provided for receiving the bare end of an electrical wire of a pair of insulated wires which are inserted into the passageways so as to pass therethrough against the ends of the spring arms whereby the spring arms will deflect and will force the bare ends of these wires against the housing walls of the electrical device. The ends of the spring arms are provided with widened portions which allow the force on the bare ends of the wire to be applied over a larger area. The release arrangement is provided by a pair of elongated apertures which extend through parallel surfaces of the housing that are aligned normal to the side dimension of the flat spring arms. The elongated apertures are offset from each other and are positioned so that their elongated axes are not substantially normal to their adjacent spring arm. The connecting wires may thus be released individually from the spring arms by movement of a pin in the elongated aperture. The aperture is dimensioned so that the spring arm cannot be deflected far enough to overstress it, and thereby cause it to take a set.

Patent ES-8206679-A1 (ES)
Title: Electrical stop motion for a textile machine.
IPC: D01H13/16
Filed: 1981-04-23
Abstract: In textile machines fed with fibre slivers, such as e.g. drawframes, immediate stopping of the machine is required in case of a sliver breakage before or on the feed table. This requirement is fulfilled using the inventive stop motion apparatus quickly and reliably, by tilting a pan arranged beneath each normally running fibre sliver and which does not contact such fibre sliver. The reaction time of the stop motion apparatus can be shortened by providing a heavy body on, and movable with respect to, the pan, the body being e.g. in the form of a steel ball. Since the pan in its working position does not contact the normally running fibre sliver, slivers of improved quality are produced and contamination of the stop motion apparatus is avoided.

Patent ES-8306931-A1 (ES)
Title: Solid-state load protection system having loss of phase sensing
IPC: H02H3/13
Filed: 1982-04-26
Abstract: A solid-state load protection system whereby a poly-phase alternating current system is monitored enabling a loss of phase feature to be used. A current sensing function is utilized so as to produce an output signal which is related to the current in an electrical circuit. Attached to the current sensing function are two capacitors each having their own signal path so as to have different charging and discharging rates. During a loss of phase condition, one capacitor discharges more quickly than the remaining capacitor with the result that the voltage across the quickly discharging capacitor, which during normal conditions is greater than the remaining capacitor, now becomes less than the remaining capacitor. A loss of phase sensing function detects this difference in potential levels thereby initiating a trip signal to the output function. The output function upon receiving a trip signal causes a light-emitting diode to conduct and also deenergizes a contactor through which a current source is connected to the load.
