Patent ES-351487-A1 (ES)
Title: A high storage density information store for recording signals in grooves
IPC: G11B11/00
Filed: 1968-03-12
Abstract: A broad frequency band signal is recorded in a grooved record by mechanical deformation of a magnetic portion of the groove, the signal components having a wavelength longer than a predetermined limit modulating a carrier of wavelength shorter than the limit. This arrangement is said to improve-storage density. The remaining signal components are either mechanically recorded directly or by modulation of the same or an auxiliary carrier of wavelength shorter than the limit. The magnetic portion 18 may be located on the lands separating adjacent grooves for playback by a magnetic head riding on the lands or (Fig. 4, not shown) the portion may form one groove wall, the record being played back by a magnetic head riding in the groove. Sound and vision signals may thus be recorded. The inherent remanence of the record or an auxiliary biasing field are employed for playback. Therecord may be copied by pressing.

Title: Platen press for processing sheet material
IPC: B31B50/02
Filed: 1968-07-13
Abstract: Sheets are fed to and through an embossing or corrugating machine having reciprocating platens 1, 2, Fig. 1, by gripper bars 4, Figs. 1 and 2, on intermittently movable endless chains 3, the leading edge being registered at a receiving position 12 and a working position 5.

Patent ES-364474-A1 (ES)
Title: Three-phase regulator systems
IPC: G05F1/20
Filed: 1969-03-07
Abstract: A voltage regulator for a three phase A.C. supply 182 comprises an autotransformer 192 whose winding 193 is connected across one phase of the supply 182 and has tapping points 194, 198 connected to bidirectional A.C. switches 204, 202 which, together with the other two unregulated phases of the supply 182, supply a rectifier 214 and load 184, the A.C. or D.C. output voltage being sensed and compared with a reference in the circuit 224 to provide an error signal to the firing control 226 for the switches 202, 204, such that the ratio of their conductive times during each half cycle of the supply 182 is adjusted to maintain the output voltage at the reference value. Members 224, 226 are conventional and produce operation in which the initial portion of each half cycle is passed by the lower voltage tapping 198 and the change to tap 194 occurs at an instant determined by the error signal. The switches 202, 204 may comprise reverse-parallel connected controlled rectifiers as shown, a single bidirectional static switch or a static switch across the output of a single phase, full-wave bridge rectifier. The tap positions may be adjusted to provide buck or boost only. It is explained that the described embodiment provides indirect control of the voltage VC1A in addition to direct control of the voltage VBC1, so that some type of control is provided for substantially two-thirds of the time, Fig. 9 (not shown). The latter Figure illustrates the characteristics of voltage and current against time for the condition in which the regulator is connected such that the unregulated line voltage VAB leads the directly-regulated line voltage VBC1, which condition is vectorially illustrated in Fig. 8 (not shown). This regulator connection is suitable for a load having a unity or leading power factor, since it prevents a short circuit condition in which the switch 204 is made conductive before the current through the switch 202 has reached zero. If the load has a lagging power factor, the appropriate regulator connection to prevent the short circuit condition is that in which the unregulated line voltage lags the directly regulated line voltage, the vector diagram and voltage-current characteristics for this connection being discussed, Figs. 10 and 11 (not shown). The-Specification also describes two other regulators, Figs 1 and 4 (not shown), which are not embodiments of the invention and which respectively employ three and two tapped transformer windings connected in closed and open delta between the three phase supply and the output to the load. These embodiments have pairs of switches similar to 202 and 204 for each winding, which switches are controlled in like manner to -maintain a - desired output voltage. The vector diagrams and voltage-current characteristics for these embodiments are discussed, Figs. 2, 3, 5 and 6 (not shown).
Patent ES-382773-A1 (ES)
Title: Nuclear fuel assembly with flow channel restraining means
IPC: G21C3/322
Filed: 1970-08-14
Abstract: A nuclear fuel assembly comprises a plurality of fuel rods in spaced array between upper and lower tie plates, a removable open-ended tubular flow channel surrounding the array and adapted to fit adjacent a peripheral surface of one of the tie plates, and restraining means attached to this tie plate for restraining lateral movement of the flow channel away from the tie plate. As shown in Fig. 3a, flow channel 36 is a sliding fit over a lower tie plate 27 formed with a nose piece 17 having openings 39 to receive pressurized coolant which flows upward among the fuel rods 26. To avoid stagnation of the coolant in the spaces between fuel assemblies mounted in a reactor core, a portion (of the order of 5 to 6%) of the coolant is allowed to leak into these spaces from between the tie plate 27 and the flow channel 36. (Coolant may also leak through passages 48 in the tie plate 27 and/or through passages 49 in the flow channel 36). Leakage is controlled by limiting the deflection of the flow channel 36 away from the tie plate 27, by means of a sleeve 40 which abuts an inner shoulder 41 formed on the tie plate and is welded, as at 42, to an outer shoulder 43. The sleeve 40 and the peripheral surface 44 of the tie plate 27 thus form a longitudinally opening slot for receiving the lower portion of the flow channel 36. The leakage flow path is thus substantially lengthened, increasing the leakage flow resistance, and the sleeve 40 substantially prevents the deflection of the flow channel 36 away from the tie plate 27. In a modified version the sleeve 40 is formed with corrugations to increase the leakage flow resistance and increase the rigidity of the sleeve. In a second embodiment (Fig. 4, not shown) the lower tie plate is fitted with a series of headed studs for engaging a corresponding series of longitudinal open-ended slots in the lower end of the flow channel. In a third embodiment (Fig. 5, not shown) a longitudinally opening groove or seat formed in the lower tie plate receives the lower end of the flow channel. Since the groove or seat is relatively shallow, a retainer spring arrangement is provided for urging the flow channel into engagement with the channel retainer seat.

Patent ES-402857-A1 (ES)
Title: Nozzle
IPC: B05B1/12
Filed: 1972-04-25
Abstract: A nozzle to provide either a weak dispersed jet or a strong concentrated jet comprises a sprayer with stages in the form of hollow rings joined together, each ring having the same inner diameter as the others, the stages having slant perforations for the emission of liquid.

As the regulator is further inserted in the sprayer, stages are progressively cut out until only the end one, pierced with a few axial holes, emits liquid in a concentrated jet.
