Patent ES-427461-A1 (ES)
Title: Data resynchronization employing a plurality of decoders
IPC: H04L1/00
Filed: 1974-06-20
Abstract: Electrical signals recorded on a magnetic medium as magnetic indicia represent digital data. Digits of data are recorded as encoded pairs of indicia (couples) by corresponding pair of signals. Successive encoded indicia are recorded on the medium serially in sequence for example, in stripes oriented diagonally across magnetic tape. During reading, defects in the medium, or errors in data transfer, resulting in a loss of synchronization between encoded indicia and the digit represented, are compensated for. Encoded indicia are continuously compared with a resynchronization pattern dispersed throughout recorded data at regular intervals. When an error is detected, the encoded indicia are decoded and stored in two buffers, each storing sets of digits decoded from differently chosen indicia pairs. The contents of one of these buffers is thereafter utilized when a resynchronization pattern identifies the correct set of digits.

Title: Circuit for recognizing a pulse waveform and an ignition system for an i.c. engine including such a circuit
IPC: F02P7/067
Filed: 1975-11-21
Abstract: A pulse waveform recognition circuit includes an input stage consisting of a tuned circuit tuned to approximately the frequency of a sinusoid to half-waves of which the pulses to be recognized approximate. A transistor is biased to conduct weakly and has its base coupled to the tuned circuit so as to be turned on by a pulse within the band width of the tuned circuit. The transistor drives a monostable multi-vibrator with a frequency dependent feedback circuit which causes the reversion time of the multi-vibrator to decrease as the frequency of triggering increases and which also increases the threshold voltage required to trigger the monostable circuit as this frequency increases. The circuit is used in an ignition system for an i.c. engine.

Patent ES-452150-A1 (ES)
Title: Common control signaling extraction circuit
IPC: H04Q11/04
Filed: 1976-10-06
Abstract: A signaling extraction circuit utilizes common control circuitry to carry out the signal extraction function for all of a plurality of time multiplexed, digital data groups (digroups), each of which comprises 24 time division multiplexed, PCM encoded channels. Each digroup uses eight bits for transmitting digital information for each channel, but the eighth bit (D8) is borrowed for signaling purposes in every sixth frame. To identify these signaling digits, signaling frame information is inserted in a digroup bit stream in the framing bit position of every other frame (i.e., the subframes). A signaling subframe pattern store comprising a shared recirculating memory serves to maintain a continuing real time record of the pattern of the signaling framing information for each digroup, as well as a test digroup. When a predetermined pattern has been recorded for a digroup (i.e., a zero subframe bit preceded by a string of exactly three ones, or a one subframe bit preceded by a string of exactly three zeros) a signal bit store is enabled to receive the D8 bits of the signaling frame which follows the recording of said predetermined pattern.

Patent ES-473270-A1 (ES)
Title: Process of purifying plant anthocyanin colors
IPC: A23L1/275
Filed: 1978-09-12
Abstract: Extraction of purified plant anthocyanin colors particularly from dark grapes by treating impure materials to insure discrete monomeric anthocyanin molecules in solution and then passing the solution through ultrafiltration membranes to retain soluble and/or cloudy macromolecular, e.g., colloidal, impurities upstream that produce, an aging, haze and sediments, and pass the monomeric anthocyanins downstream for further concentration as liquid or powder to give a stable color concentrate that can be used as a color additive. For example, fruit solids may be treated with sulfur dioxide solutions to ionize, decolor and insure the monomeric state of the pigment molecules (change from anthocyanins to chromon 2-and 4-sulfonates), ultrafiltering the solution to pass the anthocyanins downstream while retaining upstream the macromolecular components such as pectins, tannins, proteins, complexes thereof, etc., optionally stripping the sulfur dioxide from the ultrafiltered solution to regenerate the original anthocyanins from the chromen sulfonates, and thereafter concentrating said anthocyanins by evaporation to a highly concentrated liquid from which unstable pigments with acyl groups in the molecule may optionally be removed by controlled precipitation at reduced temperatures. Alternatively, the liquid with or without the controlled precipitation may be further concentrated to powder.
Patent ES-475048-A1 (ES)
Title: Electrolytic capacitor provided with a pressure relief valve
IPC: H01G9/12
Filed: 1978-11-14
Abstract: Electrolytic capacitors are provided with a pressure-relief valve which opens if the gas pressure inside the capacitor exceeds a given value to relieve the pressure. In the case of severe electrical overloading, however, the gas-relief passage usually is of insufficient size to prevent excessive pressure build-up, and there is a possibility of explosions. The present invention provides a capacitor in which the pressure-relief valve comprises a venting aperture in a bowl-shaped recess member with the aperture being closed by an elastic member held in compression over the aperture by a thermoplastic strip secured at its ends to the wall of the capacitor housing. The valve is self-sealing for minor pressure increases, but with severe increases a rapid temperature rise of the capacitor roll softens the thermoplastic strip which then allows the elastic member to be blown away so that the aperture becomes directly open to the atmosphere and allows the excessive pressure to be released very rapidly to prevent any possible explosion.
Patent ES-482672-A1 (ES)
Title: Detection of failure of consumers of electrical current
IPC: G01R31/44
Filed: 1979-07-09
Abstract: To detect the failure of e.g. a lamp (2) supplied from a D.C. source (4) through a switch (3) controlled by a manually-operated member (5), a resistance (1) of much greater value than that of the lamp (2) is connected across the switch (3), and the voltage V1 across the resistance (1) is used for the required detection. If the lamp (2) goes open circuit, then when the switch (3) is non-conductive the voltage V1 is low instead of high, while if the lamp (2) is short circuited then when the switch (3) is conductive, due to the finite resistance of the switch (3), the voltage V1 is high instead of low. To ensure failure detection regardless of the condition of the control member (5), the switch (3) is caused cyclically to incurse momentarily into the opposite state from that dictated by the control member, so that either type of failure can always be detected appropriate clock pulses are supplied from a generator (6). The equipment is particularly suited to detecting the failure of lights on a motor vehicle.
