Patent ES-372947-A1 (ES)
Title: Oscillograph with electron beam tuning indicator tube
IPC: G01R13/04
Filed: 1969-10-28
Abstract: An oscillograph for displaying the waveform of an A.C. signal incorporates a magic band type electron beam tuning indicator tube to which the signal is applied, together with a mechanically driven dissecting arrangement for enabling length of the light band of the tube to be displayed as a function of time, the dissecting arrangement consisting of a slotted member with equally spaced narrow slots extending in the direction of change of the light band. The arrangement is driven such that the direction of movement of the slots is perpendicular to the direction of change in length of the light band. The slot spacing may be the same as, or larger or smaller than, the width of the tube. The arrangement consists of a slotted cylinder in which the magic band tube is accomodated. To show oscillograms of two voltages, the arrangement may have two rows of equally spaced slots, each passing along a respective part of a twopart light band. The slots of the two rows are relatively offset by half the spacing between adjacent slots, which is twice the width of the light band. The electron beam tube is supplied with the two voltages in an alternating rhythm such that the oscillograms of the two voltages are separately registered by the upper and lower halves of the light band. The arrangement may be used to display Lissajous figures by periodically reciprocating a single slot in front of the light band, e.g. by means of spring induced torsional vibrations or a rotating shaft and eccentric. To display the output from e. g. a model generator, the generator may be driven by a motor which also drives the slotted arrangement of the oscillograph, the generator output being applied to the magic band tube. In an arrangement for determining phase difference between two alternating voltages applied to the oscillograph, the slotted arrangement is driven by a synchronous motor with a rotatable casing, which enables the oscillogram to be laterally displaced. The motor is rotated so that a characteristic point of one oscillogram aligns with a vertical graduation and then so that an equivalent point of the second oscillogram makes the same alignment. The difference in rotation gives the required phase difference.

Title: Purification of phosphoric acid
IPC: C01B25/22
Filed: 1973-04-25
Abstract: The novel process is employed to produce purified phosphoric acid or purified phosphate from a phosphoric acid obtained according to the wet process. This involves bringing the acid into contact with a dialkyl ketone having 5 or 6 carbon atoms. Essentially, the weight ratio is from 0.5:1 to 2:1. The phosphoric acid is then extracted into the organic phase, so that a ketone phase is formed in which the H3PO4 concentration is from 28 to 40% by weight. The organic phase is then brought into contact with water or an aqueous solution of a base. An aqueous phase is thus obtained which contains phosphoric acid or a phosphate with a purity higher than that of the phosphoric acid employed obtained from the wet process. If a ketone having 5 carbon atoms is used, the ketone phase is brought into contact in counter-current with water in at least two stages.

Patent ES-440924-A1 (ES)
Title: Apparatus and method for treating a textile web
IPC: D06B1/08
Filed: 1975-09-12
Abstract: The treatment takes place by means of a vaporous or gaseous medium flowing out through a nozzle (1) at at least approximately sonic speed. The textile material (5) to be treated is guided past the mouth surface of the nozzle (1), extending over the width of the textile material, by means of a progressive-motion element (6, 7) arranged respectively in front of and behind the nozzle (1) in relation to the treatment zone. The vaporous or gaseous medium at the same time flows through this material (5). The textile material (5) is guided past the nozzle (1), the wedge-shaped outer contour of which forms an angle of approximately 60 DEG , in such a way that a particular textile-material part (5) passing this nozzle (1) rests on the nozzle mouth and is pressed against this. The textile-material parts running towards the nozzle (1) and those running away from this nozzle with a change in their direction of movement form an angle which is larger than the wedge angle of the nozzle outer contour. The effect of the flowing medium on the textile material is increased substantially as a result of this measure.
