Patent ES-230655-A1 (ES)
Title: Method of producing essentially cis rubbery polyisoprene
IPC: C08F136/08
Filed: 1956-08-29
Abstract: Isoprene is polymerized to an essentially cis1,4-polyisoprene in the presence of metallic lithium and a saturated hydrocarbon solvent liquid under reaction conditions and in the substantial absence of oxygen and oxygen-containing compounds. The hydrocarbon diluent may be petroleum ether, or aliphatic and cycloaliphatic hydrocarbon solvents such as propane, n-butane, n-pentane, n-heptane and other normal and branched chain liquid hydrocarbons up to dodecane, cyclopentane and cyclohexane. Low molecular weight solvents are preferred in an amount of at least 50% by weight of the total reactant charge. The process is otherwise similar to that of Specification 814,676, examples being given to illustrate the advantages in polymer properties gained by the use of the diluent.
Patent ES-239126-A1 (ES)
Title: New colouration process for cellulosic textiles
IPC: C09B62/537
Filed: 1957-12-14
Abstract: Cellulosic textile materials are dyed or printed by applying a dyestuff, e.g. an azo, nitro, anthraquinone or phthalocyanine dyestuff, which contains at least one solubilizing group, such as a sulphonic acid group, and at least one -SO2R group, in which R represents a beta-chloroethylamino or a beta-bromoethylamino radical, and also applying before, together with or after the dyestuff, an acidbinding agent such as a caustic alkali, sodium carbonate or bicarbonate, trisodium phosphate, sodium metasilicate or hydrated magnesium oxide. The dyestuff solutions or pastes may contain the usual adjuvants such as sodium chloride, sodium sulphate, urea, sodium alginate, cellulose ethers, starch, locust bean gum or a water-in-oil or oil-in-water emulsion. The dyestuff and/or acid-binding agent solutions may be applied at temperatup to the bolres in. When the dyestuff and the acid-binding agent are applied in succession a drying operation may be applied between the two treatments. Fixation of the dyestuff may be effected by drying alone, or by heating or, in the case of printing, by steaming. In the case of printing, other dyestuffs such as leuco esters of vat dyestuffs and dyestuffs obtained by reacting colouring matters containing halogenomethyl groups with tertiary amines or thioureas may be printed alongside. Numerous examples of dyeing and printing (including one of discharge printing with a reducing discharge) are given. The dyestuffs may be obtained by treating an azo, nitro, anthraquinone or phthalocyanine dye containing a plurality of sulphonchloride groups with b -chloro-(or bromo-) ethylamine. Nitro dyestuffs may also be obtained by reacting an o-chlornitrobenzene carrying a b -chlorethylsulphonamide group with a primary aromatic amine carrying a solubilizing group, such as 4-aminoanisole-3-sulphonic acid. Azo dyestuffs may also be made by diazotizing primary amines containing -SO2R groups, such as m-aminobenzenesulphon-b -chloro-(or bromo-) ethylamide or aniline 3 : 5-di-(sulphon-b -chlorethylamide), with various coupling components, many of which are specified.
Patent ES-319505-A1 (ES)
Title: System for processing synchronous digital information signals
IPC: H04L7/00
Filed: 1965-11-12
Abstract: In a system for deriving a synchronizing signal from data accompanied by noise, means is provided for extrapolating the sync. signal derived in a relatively noise-free period to a previously occurring noisy period. The received data is recorded on one track of a magnetic tape. On a second track the actual time is recorded in m.sec. intervals. From this track a counter derives a number representing minutes, second and m.sec. From the recorded data a computing arrangement determines the time instant t 0 of the first sync. pulse of a series of sync. pulses derived during a noisefree period and the average time interval separating adjacent sync. pulses. It also determines an earlier instant t 8 at which, it is calculated, a sync. pulse should have occurred: t 8 is during a period of high noise level. The recorded data is then read again, and when the recorded time track indicates the same value as the calculated t 8 a pulse is recorded on a third track, this acting as a sync. pulse track. To the calculated value t 8 is now added a value approximately equal to the time difference between the first two sync. pulses, i.e. t 1 -t 0 (the method of determining this value is detailed in the Specification), and when this sum equals the recorded time a further pulse is recorded on the sync. track. This process continues until all the sync. pulses up to the first sync. pulse, at t 0 have been inserted on the sync. track, whereafter the sync. pulses derived from the data in known manner are recorded. The data on the first track is subsequently synchronously demodulated using the pulses on the sync. track.

Title: Resonant bandpass filter having two undesired frequency cancellation traps
IPC: H03H7/01
Filed: 1968-06-05
Abstract: A bandpass filter includes rejection or trap circuits for attenuating signals of two different frequencies within the passband and is intended for use in the I.F. amplifier of a T.V. receiver, the two frequencies corresponding to the accompanying sound carrier and the adjacent sound carrier. As shown in Fig. 1, the filter couples an input terminal I to an output terminal O and is connected to an I.F. supply 11. Arranged in series between the terminals I, O is a variable capacitor 13 and inductors 14, 15 connected in series mutual aiding relationship, the mutual induction together with capacitors 13, 16 acting as a resonant bandpass network. A parallel resonant network 19, 20 connected between the lead 17 and earth develops at the two frequencies to be rejected voltages which cancel the voltages developed by the inductors 14, 15 so that a null output occurs at terminal O. The network 19, 20 is caused to provide the critical value of impedance at the two different frequencies by inductively coupling it to an additional resonant network comprising an inductor 21 and capacitor 22, the two resonant networks being also coupled by a capacitor 23. The two networks 19, 20 and 21, 22 together act as an overcoupled double-tuned network and reject frequencies of 41À25 and 47À25 mHz, the network 19, 20 being tuned in the vicinity of 50 mHz and having a low inductance to capacity ratio. The network 21, 22 has a relatively high Q and high inductance to capacity ratio and when uncoupled from the network 19, 20 resonates at 49À5 mHz however, when the network 21, 22 is coupled to the network 19, 20 it resonates at 41À9 mHz. Fig. 2 (not shown) shows how the filter is applied to a television receiver intermediate frequency amplifier system.

Title: Chroma processing circuitry with selectable color correction mode
IPC: H04N9/64
Filed: 1971-05-14
Abstract: Chroma processing circuitry for a color television receiver wherein nominally derived primary color signals in accordance with extracted reference information in a first selectable mode of operation may be suitably modified in a second selectable mode of operation to minimize the effect of any phase errors otherwise readily discernible as undesirable departures in fleshtone hues. The referenced modification comprises a predetermined reduction in green-purple color information relative to derived luminance and orange-cyan information. Three embodiments are disclosed. In one such embodiment employing I and Q demodulation techniques, the chroma signal as applied to the input of the included Q demodulator is selectively reduced by associated control circuitry the signal information along the Q axis or demodulation angle representing essentially green-purple color information. In another embodiment, employing convention (R-Y) and (B-Y) color difference demodulators, the desired reduction in green-purple information is provided by suitable alteration of the respective phase delays effected in components of the reference signal selectively applied to the demodulators which in turn alters each of the demodulation angles at which such demodulators operate. In still another embodiment, appropriate modification of the final primary color signals is accomplished by selected changes in the circuit parameters of an output matrix network associated with the color difference demodulators.
