Patent ES-413914-A1 (ES)
Title: Color information translating systems
IPC: H04N9/85
Filed: 1973-04-18
Abstract: A color encoding format is disclosed wherein a chrominance signal in the form of a modulated subcarrier is buried in the midband of a wider band luminance signal. Comb filtering of the luminance signal midband prepares "troughs" in the luminance signal frequency spectrum. The chrominance signal is complementarily comb filtered to confine it to components falling in the vacated troughs of the luminance signal frequency spectrum. An illustrative use of this encoding format is in video disc recording. In subsequent processing of the encoded signals, as, for example, in playback of the video disc, the buried subcarrier chrominance signal may be separated from the midband luminance components by comb filtering, with substantial assurance of freedom from all crosstalk between the shared band components (including freedom from crosstalk by "diagonal" components). Systems (e.g., for recorder use) are shown for direct encoding into the buried subcarrier format, and for transcoding from NTSC format into buried subcarrier format. Systems (e.g., for player use) are also shown for transcoding from buried subcarrier format to NTSC format.

Patent ES-428420-A1 (ES)
Title: Binder compositions
IPC: D06M15/41
Filed: 1974-07-19
Abstract: A process is disclosed for forming bonded fibre and fibre products by utilisation of an improved process for neutralising the catalyst employed in forming the A stage phenol-aldehyde resin or condensate. This condensate is the actual bonding agent which, when incorporated in a diluted form in a binder composition and sprayed onto the fibres and subsequently heated in an oven, cures and bonds the fibres to one another. The condensate is a phenol-aldehyde condensate which is the result of reacting a phenol and an aldehyde in the presence of an alkali metal or alkaline earth metal hydroxide as catalyst to form an A stage or resole resin. The catalyst, once the reaction has been completed, is then neutralised, either before or after dilution, with an acidic lignosulphonate, or a liquor containing such material. An organic or mineral acid can be utilised in conjunction with the lignosulphonate, or lignosulphonate liquor, so as to avoid adding excessive amounts of lignosulphonate. The invention is also directed to the novel processes for forming the resin and binder composition disclosed.
Patent ES-433232-A1 (ES)
Title: Method of continuously casting steel strands, in particular slabs
IPC: B22D11/124
Filed: 1974-12-20
Abstract: A method of continuously casting steel strands, in particular slabs in a continuous casting plant, involves the withdrawal of the strand from a cooled, oscillating mold and the further cooling of it in a secondary cooling zone arranged to follow the mold. The oscillation frequency of the mold and the lowering speed of the strand are coordinated with each other so that the distance between the oscillation marks, defined as the quotient of the lowering speed in m/min to the mold frequency in strokes/min, amounts to maximumly 0.018 m. The oscillation marks that occur on the strand surface constitute dangerous points of weakness which ultimately lead to the formation of cracks. By the method of the present invention it is possible to eliminate the crack formation altogether or at least to reduce said risk to a minimum.

Title: Motor vehicle with headlamp tilting mechanism
IPC: B60Q1/08
Filed: 1975-03-08
Abstract: The motor vehicle is provided with headlamps mounted on a common cross rod which is angularly sprung by means of a tilting system including a lever secured to the cross rod. The headlamps are normally urged into an extreme downwardly tilted position by means of a manually operable device. In one form, the manually operable device takes the form of a solenoid having an operating rod which engages lever attached to the cross rod. The solenoid is electrically connected with a manually operable headlamp lighting switch. The arrangement is such that when the solenoid is de-energised, the operating rod thereof urges the lever into an extreme position in which the headlamps are tilted downwardly. When the headlamp lighting switch is operated to illuminate the headlamps, the solenoid attracts the rod and so releases the lever secured to the cross rod so that tilting of the headlamps can be effected by the headlamp tilting mechanism.

Patent ES-481618-A1 (ES)
Title: Disposable female contraceptive
IPC: A61F6/06
Filed: 1979-06-16
Abstract: Disclosed is a disposable contraceptive in which a first member engages the vaginal vault and a second member, secured to the first member, engages and closes the cervical opening. The first and second members are substantially discoid, with the second member smaller in discoid area than the first. The second member is a generally impermeable sponge-like material which is lubricated to aid in adhesion and closure of the cervix. The first member is generally resiliently closable so that the overall dimension of the contraceptive may be reduced in size for insertion into the vaginal vault. The first member is defined at least by opposed anterior and posterior portions which engage the respective anterior and posterior portions of the vaginal vault. The second member is coupled or joined to the first member at the posterior portion. In one embodiment, the second member is a sponge joined to a film. The film is held in position to define the first discoid member surface by a rim. In other embodiments, the first and second members are resiliently joined at the posterior portion so as to urge the second member into positive engagement with the cervix. Thus, a finite resilient nylon filament is bent into a figure 8 and covered with a soft, yieldable, foam plastic covering. By folding at the intersection of the upper and lower loops, the contraceptive is formed. In another example, a liner of resilient plastic in the shape of conjoined circles is covered by a soft, flexible, plastic envelope. In yet another example, an annular discontinuous rim is covered by a foam plastic. The rim has an integrally formed tongue extending therein and about, to which may be secured (by any well known means) a sponge-like impermeable plastic second member.
