Patent ES-469934-A1 (ES)
Title: Integral manifold absolute pressure and ambient absolute pressure sensor and associated electronics
IPC: F02D45/00
Filed: 1978-05-17
Abstract: A combination manifold absolute pressure and ambient absolute pressure sensor utilizing a single absolute pressure sensor and a second sensor which is devised to sense the difference between the manifold pressure and atmospheric pressure. The second sensor is provided with a switch mechanism actuated by a diaphram at a preselected pressure difference between manifold pressure and atmospheric pressure. The actuation of the switch mechanism causes a sample-and-hold circuit to sense the instantaneous manifold absolute pressure at the time of actuation of the switch and electrically add the sensed manifold pressure to the set difference between the manifold pressure and atmospheric pressure to provide a signal indicative of ambient absolute pressure. This signal is utilized to provide altitude compensation in a fuel injection system.

Title: High voltage electric insulators made of resin-bonded glass-fibre and organic material and process for manufacturing same
IPC: H01B17/32
Filed: 1978-07-26
Abstract: The electrical insulator for high tension has a central support of vitreous resin (1) and finning of EPR elastomer (5, 7), in which the fins are applied to the support: globally, in a single body, or individually or in groups and directly, or with interposition of a tubular sleeve (3) of said EPR elastomer. The parts are assembled into a single whole by means of an appropriate olefin polymer-based self-vulcanising adhesive mixture. The pertinent production process provides for the formation and vulcanisation of the fins (5, 7) and of the tubular sleeve (3) according to choice: separately - with subsequent assembly onto the support (1, or 1 + 3) - or directly onto the actual support (1, or 1 + 3). The insulators obtained in this manner are characterized by a very low weight/mechanical strength ratio, and by there ability to tolerate the intense operational vibrations, as compared with the conventional porcelain insulators. Moreover, they exhibit substantial properties of resistance to aging and to surface discharges, and high auto-extinction capability, as compared with insulators made from organic material of the prior art.

Patent ES-8204255-A1 (ES)
Title: Circuit arrangement for modifying dynamic range
IPC: H04B1/04
Filed: 1981-06-29
Abstract: Compressor and expander circuits respectively are arranged in series, the circuits each having bilinear characteristics in which there is a low level portion of substantially constant gain up to a threshold, an intermediate level portion, above the threshold, of changing gain providing maximum compression ratio or expansion ratio, and a high level portion of substantially constant gain different from the gain of the low level portion. The high and low level portions thus each have a constant compression ratio of 1:1. Over the intermediate portion, the compression ratio 10 or 12 rises to a maximum 10b or 12b such as 2:1. The intermediate level changing gain portions of the characteristics are staggered between the series circuit to the extent that the resulting overall characteristic has a maximum compression or expansion ratio substantially no greater than that of any single circuit while providing an increased difference between the gains at low and high input levels (that is, providing increased compression or expansion) than for any of the circuits individually.

Patent ES-8204899-A1 (ES)
Title: Television ghost detection and cancellation system controlled over several lines of a vertical retrace interval
IPC: H04N5/21
Filed: 1981-08-07
Abstract: A ghost detection and cancellation system is provided in which the horizontal sync pulses of a first sequence of lines in the vertical retrace interval are used as training signals for the detection and verification of the presence of a ghost signal. This detection procedure results in the development of a signal which reliably indicates the time location of the ghost signal with respect to the main television signal. The location indication signal is then used to select the appropriate tap of a tapped delay line. The delayed video signal from the tapped delay line is then applied to the control amplifier of a ghost canceller for the generation of a pseudo-ghost signal during a subsequent line or lines of the vertical retrace interval. The pseudo-ghost signal is combined with the original video signal to cancel its ghost signal component. By sequentially performing ghost detection and cancellation during numerous lines of the same vertical retrace interval, ghost detection and cancellation is quickly and accurately achieved.

Title: Regulation method for a heating system, and device for carrying it out.
IPC: G05D23/24
Filed: 1982-05-17
Abstract: A space heater, designed to maintain the temperature of a room between a lower limit Tm and an upper limit TM, is controlled by a system including a sawtooth-wave generator working by way of a clipping stage into a differential amplifier also receiving a monitoring signal representing the difference between an output voltage of a temperature sensor and a reference voltage. The differential amplifier emits a train of command pulses of temperature-dependent duration which temporarily reduce the mean power of the heater to a fraction of its maximum value, as by periodically interrupting its fuel supply when that heater comprises a gas burner. The heater is cut off for an extended period when the upper range limit TM is exceeded and is then restarted when the temperature falls beneath the lower limit Tm. In the case of a gas burner of the catalytic type, the cut-in is accompanied by a supply of additional gas to the burner for a limited time.

Patent ES-8402943-A1 (ES)
Title: Testing operability of a controlled rectifier device.
IPC: G01R31/26
Filed: 1982-11-12
Abstract: The state of operability of a semiconductor device (1), e.g. a TRIAC, is tested by introducing narrow switching pulses into its normal control signal (7, 8) and sensing the resulant momentary change of state. Sensing is by means of a light emitting diode (13, 16) connected in parallel with the device (1) so that when sufficient voltage appears across the device terminals, as in the non-conducting state, the diode (13, 16) will be illuminated. The L.E.D. output is received by a photo-responsive device (20, 19) and corresponding signals (21) supplied to means for correlating these with the original introduced test pulses. Lack of correspondence between these indicates that the semiconductor (1) is inoperable.
