Patent ES-357533-A1 (ES)
Title: Speed control apparatus with eddy current clutch and brake means
IPC: B60T13/74
Filed: 1968-08-24
Abstract: Rotation of a motor 27 is transmitted to an output shaft by an electromagnetic coupling II of the kind which provides a driving torque if one winding W1 is energized and a braking torque if a second winding W2 is energized. The invention concerns the energization of the windings to maintain a constant speed on the, output shaft. A composite error signal is generated which has a D.C. component, which varies as a function of the deviation of the actual speed from a desired speed, and an A.C. component, this signal being applied to means whereby when the signal exceeds a first threshold the first winding is energized and when it falls below a second threshold the second winding is energized so that the average voltages applied to the windings vary as functions of the D.C. component to maintain the desired speed. A tachogenerator G1 gives an A.C. signal whose amplitude varies with speed this signal is rectified and partially smoothed to give a D.C. with superposed A.C. The latter is of substantially constant amplitude since as speed rises, the frequency of the signal also Increases and the smoothing circuit becomes more effective. To this is added a D.C. bias representing the desired speed and set by a potentiometer (R32) across a zener diode Fig.2 (not shown). The composite error signal thus formed is amplied to the inputs of two overdriven amplifiers (37, 39) which respectively deliver square pulses to the two windings of the coupling whenever the signals rises above or falls below the respective threshold. A switch is provided to disconnect winding W1 and to connect the amplifier of winding W2 to a source of a suitable braking signal to bring the shaft 13 to a halt. The brake threshold can be set by a potentiometer (R18) Fig. 2 (not shown) to adjust to separation between the two thresholds giving either a dead band or an overlapping region where the two windings are energized alternately. The brake winding may be replaced by a second driven winding allowing the load to be driven in both directions.

Patent ES-429884-A1 (ES)
Title: Storage containers for liquefied gases
IPC: F17C13/08
Filed: 1974-09-07
Abstract: Large-scale cryogenic tanks such as for L.N.G. are supported on spaced-apart wooden bearer members which are part of the outer insulation. The weight of the loaded tank causes the floor of the tank to deflect on each side of the bearer members so that the loading increases to a degree that sometimes crushes the edges of the bearer members. Means are described for obviating this effect by inserts of resilient material extending inwardly from the sides of the bearer members, permitting sufficient deflection of the top edges of the bearer members to spread the load more uniformly over the bearer member.
