Patent ES-348789-A1 (ES)
Title: Control for photocomposing apparatus
IPC: B41B17/34
Filed: 1967-12-29
Abstract: A photographic type-composing machine comprises a character drum 15, Fig. 1, comprising a disc 23, Figs. 2 and 6, having positionrepresentative slits 17 sensed by a photo-cell 19, and two font rings 22, 23, each comprising eight segments mounted on eight drum segments 37a-37A. Each ring, such as 22, Fig. 5, is provided with transparent characters 24 in groups of eight differing in size and style and defining eight peripheral tracks, the groups being aligned with slots 37i in the drum segments, and the tracks consisting of sets of six interlaced characters passing through a projection zone 31c of an optical system. The rings also contain, for each group of characters, character-representative code holes 25, a character-ready hole 25a and a position-representative slit 26. A mask 36 is mounted inside the drum segments, and is provided with slots 36a aligned with one of the six groups in a set, slots 36b aligned with the corresponding marks 25, 25a, 26, and shorter slots 36c 36d for short lines. There are two series of each type of slot, one for each ring, the mask being circumferentially adjustable to one of six positions by a stepping motor 41 through a cam 42. The intersection of a slot 36a or 36c and the zone 31c defines one character which scans a photosensitive film 10, movable only for line spacing, as the character passes through the zone. A first optical system comprises a lamp 30 and lens assemblies 31, 31a, 32, 31b mounted on a carriage 58 for adjustment axially to the desired one of the eight tracks by means of a motor 56 through a cam 57. A second optical system comprises a light source 59 and lens assemblies 60, 61, 62, 62a, which projects light through the masks 25, 25a, 26 to a photodiode array 63, the assemblies and source being mounted on a carriage 65, which also supports the carriage 58, movable to select the font ring by mechanism 67. A computer 12 receives information from the input tape 14 and from the devices 19, 63, and controls the film feed, the mechanism 67 and motor 41, and causes momentary illumination of the lamp 30 when a character is scanning a point on the film where it is to be projected, the arrangement being such that one character is dealt with at a time, being projected on every required position of the line before the next character is dealt with. The computer also controls the flash to give a justified line, according to information as to the number of word spaces and the character widths. The computer is illustrated in detail in Figs. 7a- 7g (not shown).

Patent ES-441053-A1 (ES)
Title: Tape lifter
IPC: G11B15/64
Filed: 1975-09-18
Abstract: Various pneumatic means are shown for lifting tape locally away from a rotating head as the rotating head moves. Only the tape in the vicinity of the head is lifted. The lifting is done with minimal pneumatic force, and done only locally about the head so that recovery time for read/write operations after a lifting operation is short, Air to lift the tape can be blown from passages around the head, from passages through the head, or from passages in front of the head. Local lifting about the head is enhanced by insuring that the pneumatic air flow to lift the tape does not easily dissipate in air space between the mandrel and the head rotor.

Patent ES-451177-A1 (ES)
Title: Apparatus for purifying waste water containing organic contaminants
IPC: C02F3/12
Filed: 1976-09-02
Abstract: A cylindrical reaction chamber for purifying waste water has a separating zone extending substantially along its entire length and bounded transversely by first and second downwardly converging partition walls. The space in the vessel between the vessel wall and the first and second walls form separate waste water activation zones, in at least one of which an aerating device is disposed. Such zones are so configured that separate, oppositely directed transverse swirls of the waste water are established in the respective activating zones. A portion of the agitated water, after suitable treatment by baffle plates to remove the transverse swirling component, is introduced into the bottom of the separating zone for purification via fluid filtration. A pair of guide channels extend obliquely downwardly adjacent both ends of the separating zone, thereby providing a longitudinal circulation of waste water which promotes denitrification of certain contaminants in the waste water in the absence of aeration of the second activation zone.
