Patent ES-460184-A1 (ES)
Title: Frequency-modulated data communications receivers
IPC: H04L27/14
Filed: 1977-06-28
Abstract: This device is suitable for use under propagation conditions severely affected by interference, in particular in mobile stations, in which propagation delay differences occur at the receive location due to the alternate routing differences of the reflected carrier waves. The information losses caused by phase and amplitude distortion are thereby automatically identified according to their cause in two arrangements which complement one another, i.e. in an equaliser for dynamic cancellation and an equaliser for static cancellation. The equaliser for dynamic cancellation has a frequency discriminator (3) with a device connected downstream for noise peak detection (DE) and the equaliser for static cancellation (SE) has an amplitude demodulator (9) with a polarity inverter (11) connected downstream and controlled by a polarity integrator (12). Depending on the type of interference detected, one or the other equaliser is through-connected on the output side via a changeover switch (13) to the common output.
Patent ES-461150-A1 (ES)
Title: Preparation of foamed plastics materials with combustion characteristics
IPC: C08G18/00
Filed: 1977-07-29
Abstract: An aqueous solution of water-soluble amino resin precondensates is condensed with organic isocyanates, firstly amines and/or organometallic compounds being added to the organic isocyanate, and simultaneously, but separately from one another, a solution of the amino resin precondensate and acidic curing catalysts then being added to the mixture. Foaming inevitably occurs during this operation. The process enables the preparation of, in particular, lightweight foams without the use of particular foaming (blowing) agents. Three different catalyst groups act in concert, with no mutual inhibition. An appropriate choice of the amino resin component, the water content, the amount of polyisocyanate and the combination of the acidic, basic or organometallic catalysts makes it possible to produce, in an economical manner and in a single step and a short production time, foams having good fire and insulation properties which cure tack-free without further thermal aftertreatment.

Title: Color display tube
IPC: H01J29/48
Filed: 1979-09-06
Abstract: By deflecting the electron beams before the focusing lenses in an electron gun system for a color display tube towards the tube axis by non-symmetrical lens fields so that they converge on the display screen, it has proved possible to obtain symmetrical focusing lens fields by means of mechanically non-symmetrical electrodes the axes of which are parallel, if the beams enclose a given angle with the gun axes. This enables an easy manufacture of the electrodes and an accurate assembly of the guns. In these guns the focusing of the beams is independent of the convergence.

Patent ES-8107097-A1 (ES)
Title: Controlling apparatus of electric car
IPC: H02P7/293
Filed: 1980-12-04
Abstract: PURPOSE:To eliminate the infuluence of noises by dividing the reference frequency to 1/N by one control device, multiplying it N times by the other control device, and synchronizing with the reference signal. CONSTITUTION:A pulse signal fCH1 which is synchronized with the chopper frequency of the other phase obtained by a frequency divider 2 is transmitted and supplied to a phase comparator 6 together with a pulse signal fCH2 which is synchronized with the chopper frequency of the own phase obtained by a frequency divider 3. Said phase comparator 6 sends out the AC output whose DC component becomes zero when the phase difference of the signal becomes the desired phase difference. Therefore, if fCH2 is deviated from the desired phase difference, the AC wave having the DC component corresponding to the deviated phase difference is sent out. While the voltage VB is applied to a V/F converter 8 beforehand so that the frequency of the fCH2 signal which is sent out via the frequency divider 3 becomes a specified frequency. Therefore, the DC component from a filter 7 and said VB are added or substracted, and the calculated voltage is applied to the V/F converter 8, wherein the oscillating frequency is varied depending on said voltage.

Patent ES-8403232-A1 (ES)
Title: Fixing mechanism used in a disc actuation system
IPC: G11B19/00
Filed: 1983-02-08
Abstract: A magnetic fixing device for a disc reader moves inherently and is raised to a rest position when the surround of the disc reader and the shaft are oriented for the insertion of the disc, and it moves to a fixing position and is held in it when the disc reader and the surround are oriented for reading of the disc. The magnetic fixing device changes position when the centring hub of the shaft is coupled to the central orifice of the disc and consequently the fixing device is always in its rest position when a disc is inserted or ejected, thus eliminating scratching of the delicate surfaces of the disc by the surface or the adjacent edge of the magnetic fixing device. Preferably, the magnetic fixing device has a ring-shaped permanent magnet with multiple pairs of poles arranged around the circumference of the ring. A short-circuiting washer made from magnetically permeable material is secured in the upper part of the ring so that the magnetic flow from the permanent magnet is emitted from the lower part of the ring. The fixing device is raised above the shaft and the disc inserted by means of a raising ring made from permeable material secured at the same level as the lower surface of the upper part of the surround of the disc reader. Depending on the distance of the raised fixing device from a disc- actuating piece made from permeable material and included in the shaft, the magnetic flow emitted from the lower part of the fixing magnet is preferably transmitted to the raising ring in order to raise the disc-actuating piece in order to secure the disc. Therefore, the magnetic fixing device passes rapidly from its rest position to its fixing position and vice versa at the appropriate point in the disc-insertion or -ejection cycle.
