Patent ES-8101336-A1 (ES)
Title: Apparatus for transmitting information on an alternating current line.
IPC: H04B3/54
Filed: 1980-04-11
Abstract: Information is transmitted on one of the phase conductors of an a.c. line in a form of a series of short-duration pulselike amplitude reductions in the voltage during one and the same half cycle, whereat the pulses form a binary code word representing the information. These reductions are generated by means of a current transformator (14) in series in the phase-conductor (4). The secondary winding is short circuited by a transistor (15) controlled by a control unit (6) to be opened for a short duration for each desired pulse. When the transistor (15) is opened, a voltage regulator (17) connected across the secondary winding restricts the change in magnetic flux in the transformator core to a maximum value dependent upon the lenght of the impulse series. The current is held over a given miniumum value during a transmission by a current regulator (27) and by connecting a load (28) to the phase conductor (4).

Patent ES-8206129-A1 (ES)
Title: Keyed noise filter in a television receiver
IPC: H04N5/14
Filed: 1981-04-20
Abstract: A video signal channel in a television receiver includes a keyed filter, followed by a keyed automatic brightness control circuit for establishing a desired black or blanking level for the video signal. The brightness control circuit operates during blanking intervals of the video signal to sense the blanking level of the video signal for deriving a control signal which is utilized to maintain a desired blanking level. The filter comprises a high-pass filter circuit which is decoupled for filtering purposes during image intervals, but is coupled to the video channel during the blanking intervals for suppressing high frequency signals including noise, when present, in the video channel during the blanking intervals. The sensed blanking level and the control voltage are therefore unaffected by noise components which would otherwise impair the control signal and thereby the operation of the brightness control circuit.

IPC: H04M3/30
Filed: 1984-08-17
Abstract: An electrical system which comprises (1) a temperature-sensitive device comprising a PTC or NTC element, (2) a load in series with the temperature-sensitive device and (3) a control device in parallel with the load and the temperature-sensitive device. The control device is a device whose resistance can be changed from a high value (which may be infinite) to a low value or vice versa, by a change in the electrical or physical environment thereof, e.g. a diode, triac, thyristor, PTC device or NTC device. The system is connected to a power supply so that, under normal conditions of operation, either (a) the temperature-sensitive device has a low resistance and the control device has a high resistance, whereby the load is activated, or (b) the temperature-sensitive device has a high resistance and the control device has a low resistance, whereby the load is isolated. By an appropriate change in the power source, e.g. its size or direction, or in the physical environment of the control device, e.g. its temperature, the relative resistances of the temperature-sensitive device and the control device can be reversed, thereby isolating or activating the load. The system is particularly useful for isolating a remote load, e.g. a telephone, while retaining a continuous circuit e.g. through the legs of a telephone circuit, for example for test purposes.
