Title: Load actuating servomechanism with resonance equalization
IPC: H02P23/00
Filed: 1978-02-13
Abstract: Load actuating servomechanism apparatus includes dynamic regeneration to equalize and overcome a frequency-varying load/load drive train mechanical resonance. The drive circuitry comprises a per se conventional primary motor speed controlling rate feedback loop including a cascaded rate signal command source, summing error-signal producing node, and loop frequency response shaping filter and driver amplifier for exciting a load driving motor, and a rate tachometer signal feedback element connecting a measure of the motor output speed to a subtractive input of the summing node. To broaden the response band of the primary feedback circuit and accommodate a mechanical resonance otherwise interfering therewith, a secondary, positive feedback path supplements the input rate command with a signal dependent upon motor current, and thus upon motor load. Accordingly, output load drive automatically increases as motor current increases when a load drive retarding mechanical resonance is encountered.

Title: A method and an arrangement for the compensation of inertia forces in the indexing movement of a machine element.
IPC: F16F15/22
Filed: 1979-10-24
Abstract: When machine elements having a large mass are indexed, i.e. subjected to short, quick rotating movements, very great acceleration and deceleration forces must be transmitted via the driving means of the machine. Due to vibrations occurring, increasing the stresses on the driving means, the driving means must be dimensioned accordingly. The present invention provides a method and an arrangement for the compensation of the forces applied and thus for reducing the stresses which occur. This is performed by combining the indexing machine element with a cam disc which is contacted by a number of spring-loaded cam followers, whereby the cam disc has such a shape that the cam follower decelerates and accelerates the cam disc following the desired movement pattern of the machine element.

Patent ES-8105901-A1 (ES)
Title: Controlled D-C power supply
IPC: H02M7/155
Filed: 1980-09-10
Abstract: By controlling the phase angle at which conduction occurs in the SCR's in an SCR rectifier bridge, a d-c voltage of adjustable magnitude may be produced from a-c line voltage applied to the bridge. The specific angle at which the SCR's are fired into conduction during each half cycle of the a-c line voltage is determined by comparing a ramp-shaped pulse, produced from the line voltage during each half cycle, with an error signal which varies as a function of the difference between the desired d-c magnitude and the actual amplitude of the d-c voltage. The d-c power supply is made immune to line voltage variations by regulating the ramp-shaped pulses so that they always have the same pulse width regardless of line voltage amplitude, thereby facilitating precise control over the d-c magnitude.

Patent ES-8201320-A1 (ES)
Title: Underwater seismic source and its use.
IPC: G01V1/02
Filed: 1980-10-24
Abstract: The invention provides a sound source for use in underwater seismic testing, the source comprising a substantially linear array of a predetermined number of air guns of differing volumes. The spacing between the guns is determined by a "weighted centroid distribution", this being determined by selecting a predetermined mathematical window function which is positive at all points within the window and which approximates to the Fourier transform of a single square wave, the width of the window being selected to correspond to the desired length of the array, and then dividing the area under the curve into areas which are the same in number as the air guns, and the relative proportion between the areas under the curve being the same as the relative effective weights of the individual air guns in the array. The centroid of each such area is then determined, and the positioning of the air guns is proportional to the separation of the centroids measured on the x-axis of the function. The mathematical window function may be a Hanning or a sinc function, for example. The effective weights (i.e. the primary pressure amplitude responses) of the air guns preferably increase symmetr-ically from the ends of the array towards the mid-point thereof.
