Patent ES-372056-A1 (ES)
Title: D.c. clamping circuits
IPC: H04N5/18
Filed: 1969-09-30
Abstract: In a D.C. clamping circuit in which the output of a D.C. coupled amplifier 3 is connected through the series combination of a diode 12 and a capacitor 10 to a pulse voltage source 9, the junction A of the diode 12 and capacitor 10 is coupled through a diode 13 (instead of a resistor) to a direct-voltage input 17 of the amplifier shunted by a smoothing capacitor 14. The television signal to be restored is applied to input 1 and the circuit output is taken from terminal 8. In operation capacitor 10 is charged during the sampling periods (pulses from source 9) to the voltage difference between the pulse peak and the reference level at the collector of transistor 4. Outside these sampling periods diode 12 is cut off and at junction A appears a negative going voltage which opens diode 13 and is transmitted to capacitor 14. The resulting control-voltage is applied to the direct-voltage input of amplifier 3 for adjusting its working point. When the reference level at the collector of transistor 4 becomes more negative (less positive), the voltage at junction A becomes more negative outside the sampling periods and hence the collector current decreases and its voltage becomes more positive. Since the controlvoltage for amplifier 3 should have an absolute value, a positive current is supplied to capacitor 14 from the supply source via a large resistor 15. When the reference level at the collector of transistor 4 becomes more positive, the voltage at junction A becomes positive outside the sampling periods and diode 13 is no longer opened with respect to the more negative voltage of capacitor 14. Resistor 15 is then traversed by a more positive current which is supplied to capacitor 14 until diode 13 is again opened. A series combination of a plurality of diodes may be employed instead of the diodes 12 and 13.

Patent ES-419341-A1 (ES)
Title: Hydraulic steering control system
IPC: B62D5/28
Filed: 1973-10-04
Abstract: A power boost steering system is provided using hydraulic pressure controlled through a metering pump wherein toward the limit of travel of the vehicle wheels pressure boost is dropped and the steering mechanism then actuated only under manual power by virtue of rotation of the steering wheel. Accordingly, only manual force can be brought to bear on the steering mechanism at the ends of travel in either direction of steering so as to avoid damage which might be occasioned were hydraulic power boost used up to the point where the steering mechanism had reached its limits of mechanical motion. A particular advantage resides in the dropping of boost pressure at the servopump instead of at the servomotor in order to preserve synchronized movement between the manually operated steering wheel and the steered wheels of the vehicle.
Patent ES-419892-A1 (ES)
Title: Mounting device for optical lenses
IPC: B24B13/005
Filed: 1973-10-24
Abstract: Mounting device for grinding optical lenses. There is provided a mounting plate by which the lens is held against the grinding tool, said mounting plate being driven through a ball joint. Pressure and consequent wear on the ball joint is minimized by associating said plate with a generally cup-shaped member movable with the driving side of the ball joint into which a pressure fluid is introduced for urging the mounting plate, consequently the lens, against the grinding tool. A U-shaped sealing device is provided between the flanges of the cup-shaped member and the mounting plate for both sealing the space therebetween against escape of the pressure fluid and also for effecting a driving of the mounting plate for rotation with the cup-shaped member. Thus, the actual control of the lens is through the ball joint, and the driving of same for rotation is through the U-shaped sealing device. As a result, the thrust of the lens against the grinding tool and the radial grinding motion is sufficiently assisted that wear on the ball joint is minimized.

Title: Liquid flow control apparatus
IPC: A61M5/00
Filed: 1976-11-05
Abstract: There is disclosed liquid flow control apparatus (particularly for use where the flow takes place in the form of drops over at least part of the flow path). A valve in the flow path is controlled by a servo system in dependence on the difference between desired and actual rate of flow signals. A linear to exponential signal converter sets the desired rate of flow signal which is displayed by means of two relatively movable display members one of which is movable to a position dependent on the desired rate of flow and carries a logarithmic scale which is juxtaposed with a logarithmic scale on the other member. For example, the other member may be movable to a position dependent on the size of the drops, and the volume rate of liquid flow for any given time can be read off from the juxtaposed scale. The apparatus also includes a throttle valve comprising two relatively movable throttling members positioned on opposite sides of a flexible tube. One member is pivotable about an axis parallel with the flexible tube and the other is slidably urged towards the tube.
