Patent ES-8703714-A1 (ES)
Title: Local contraception method
Filed: 1976-04-30
Abstract: Method of local contraception by inhibiting passage of spermatozoa into the cervical canal involves modifying the physicochemical structure of the cervical mucus, pref. using >=1 coagulating agent. Novel agents for local contraception contain an effective amount of a coagulating agent (e.g. tannin, pentadigalloyl-glucose or cetyl-trimethylammonium chloride), advantageously in combination with a spermicide (e.g. benzalkonium chloride) and/or an agent which promotes and completes coagulation (pref. carboxymethyl-cysteine). In addn. to their use in contraception, the coagulant compsns are of utility in the treatment and prophylaxis of genito-urinary infections in women, since coagulation of the cervical mucus also prevents passage of unicellular organisms (esp. bacteria) through the cervical canal. Thus upward spread of infection into the uterus can be prevented in patients who have been in contact with pyogenic infections (es. gonococci).

Patent ES-8104696-A1 (ES)
Title: Television signal processing system
IPC: H04N5/50
Filed: 1980-08-28
Abstract: A selectivity network is provided for a synchronous detector, a reference signal circuit, and an AFT circuit. The selectivity network comprises a first tuned circuit coupled across two terminals of the reference signal circuit and tuned to the desired frequency of the I.F. picture carrier. A second tuned circuit is lightly coupled to the first tuned circuit and is coupled across two inputs of the AFT circuit to provide a frequency dependent phase-sifted reference signal to the AFT circuit. The first tuned circuit includes a trap circuit tuned to provide attenuation about a frequency intermediate the frequency of a sound carrier and that picture signal sideband frequency which, upon detection, results in a video signal corresponding to the intercarrier sound second subharmonic frequency. The trap in the reference signal tuned circuit minimizes quadrature distortion in the reference channel and the resultant harmonic distortion in the video signals, which causes sound buzz. The frequency notched reference signal is applied to the AFT tuned circuit, which causes a balancing of the pull-in range of the AFT circuit about the desired picture carrier frequency, thereby immunizing the AFT circuit against noise-pulling. The frequency notch in the AFT circuit at the indicated frequency also minimizes AFT effects of a frequency offset co-channel sound carrier, allowing the automatic acquisition of signals which are offset in frequency toward the lower adjacent channel.
