Patent ES-474345-A1 (ES)
Title: Balanced control waveform for reducing inverter harmonics
IPC: H02M7/48
Filed: 1978-10-19
Abstract: A particular control waveform actuates the half-bridge switching elements of a three-phase power inverter in such a manner as to balance harmonic cancellation between waveform notching and low impedance filtering in obtaining a substantial sinusoidal output signal. The control waveform allows a small amount of lower order harmonics which inherently decreases the higher order harmonics generated by the notches in the control waveform so that a small filter, e.g., a five percent filter, can be used which eliminates the need for voltage regulation under various current loads and yet both the unregulated voltage fluxations and overall harmonic content of the output signal is well within acceptable tolerances for use by an electrical power utility or the like. At the same time, the control waveform employs a relatively low per cycle switching rate which minimizes the number of off-on transitions of each of the high-current, solid state switches in the inverter thereby retaining high inverter efficiency.

Patent ES-476494-A1 (ES)
Title: Improvements introduced to a method for manufacturing cement.
IPC: C04B/
Filed: 1978-12-29
Abstract: In the production of cement, whether by a "dry" or "wet" process, one of the final stages is to heat the powdered ingredients to a temperature in excess of approximately 1427 degree C, after which the cement achieves its fundamental characteristics of being capable of setting to a hard, stone-like state, by mixing it with water and various ingredients, followed by thorough drying. In the practice of a fundamental aspect of this invention, the powdered cement ingredients are stored and/or shipped prior to the kilning stage, and when they have been taken to the general region of use they are then heated to the required temperature to produce the final cement. Another aspect is that the unkilned cement ingredients, either as slurry when prepared by a "wet" process, or forming slurry when prepared by a "dry" process, are shipped in an oil tanker for what is typically a return journey without cargo (e.g. from the United States to the Near East). A thinner is added to the slurry, reducing its viscosity, thus making it easier to pump into and out of the ship's holds.

Title: Method and apparatus for determining the internal dimension of extended hollow bodies, especially of tubes.
IPC: G01B15/00
Filed: 1979-09-18
Abstract: For the testing of notably deep-drawn tubes during manufacture it is important that the thickness of the tube can be checked.

Patent ES-8202453-A1 (ES)
Title: Light and particle image intensifier.
IPC: H01J31/50
Filed: 1980-12-30
Abstract: A light and charged particle image intensifier receives incident image conveying light or charged particles ("incident beam") and provides to data processing and video equipment signals from which the image conveyed by the incident beam can be constructed and displayed. The beam that is being processed includes visible light reflected from objects and X-ray radiation that has been passed through an object such as a human body. The image intensifier includes a scintillator and photocathode unit for converting the incident beam to photoelectrons and a charge-coupled device ("CCD") for detecting the photoelectrons and transmitting to the data processing and video equipment information relating to the quantity or energy level as well as the location of the electrons impinging on the sensing areas of the CCD. From this information, the data processing and video equipment can reconstruct the image conveyed by the incident beam. The sensitivity of the device is increased either by imposing an electric field across the photocathode and the CCD to accelerate the photoelectrons or by placing a micro channel plate ("MCP") between the photocathode and the CCD to increase the number of electrons that impinge on the CCD. Alternately, a silicon diode target can be used instead of a CCD to intercept the electrons and an electron beam gun can be used to detect the location and intensity of the charges created on the target by the impinging electrons. Finally, a grid having a number of windows can be used instead of a CCD or a silicon target to detect the location of the electron streams and a photoanode can detect their intensity.
