Patent ES-469792-A1 (ES)
Title: Apparatus for the preparation of a fluid for examination in optical analytic instruments
IPC: G01N33/50
Filed: 1978-05-12
Abstract: The measuring liquid in analytical optical devices frequently has to be treated prior to the measurement. A device suitable for this purpose is based on an optical cuvette (cell) filled with a suitable reaction solution. The sample liquid is dispensed into the reaction solution with the aid of a capillary. Normally, all the reactants for the reaction are contained in the reaction solution along with the sample liquid. In the case of the device described here, however, some of the reactants are only introduced into the reaction solution using the dispensing capillary. For this purpose, the dispensing capillary, or independently thereof an additional capillary, is filled with the reactant in the solid phase. When the sample liquid and the reactant are mixed with the reaction solution in the capillary, a chemical reaction sets in which results in a characteristic change in the optical absorption. This change serves as a basis for a photometric measurement.

Patent ES-477555-A1 (ES)
Title: Video disc player
IPC: G11B17/032
Filed: 1979-02-08
Abstract: A video disc player is provided with a stabilizing disc which during playing is disposed at a small distance above the video disc, air being admissible through an inlet restriction between the stabilizing disc and the video disc so that locally a sub-atmospheric pressure is produced as a result of the centrifugal pumping action of the video disc. In order to prevent the video disc from being drawn along when the stabilizing disc is moved upwards, an air by-pass passage is provided which via air-valve means can be opened when playing of the video disc is terminated, so as to admit an increased air stream between the stabilizing disc and the rotating video disc in order to at least substantially eliminate the prevailing sub-atmospheric pressure.

Title: Oscillating hydraulic motor.
IPC: F03C4/00
Filed: 1979-11-16
Abstract: In an oscillating motor with fluid drive, the shaft (6) is mounted in the motor housing (1), which is provided with an annular space (18) concentrically surrounding the said shaft. The space (18) is divided into two chambers by two vanes (19, 20), one (20) of which is secured on the housing (1) and the other (19) is secured on the shaft (6). The lines (31, 32) feeding in and carrying away the driving fluid open into the chambers on both sides of the vane (19, 20) fixed to the housing or to the shaft. In order to keep down the production costs and provide good sealing of the motor, the shaft (6) carries a radial disk (13) which is provided with a groove (15) of semicircular cross-section concentrically surrounding it. With its flat front face provided with the groove (15), the disk (13) rests flat on a flat radial base surface of the housing (2), which base surface has a corresponding encircling groove (16) of semicircular cross-section which, with the groove (15) of the disk (13) forms a centrally divided toroidal annular space (18). Arranged in the groove (15) of the disk and in the groove (16) of the housing end is in each case a vane (19, 20) which has the shape of a sector of a torus and the circular cross-section of which has a radius which corresponds to the radius of the grooves (15, 16). Good sealing is achieved by virtue of the fact that those flat surfaces of the disk (13) and of the housing (1) which adjoin the annular grooves (15, 16) are pressed sealingly against one another.

Patent ES-8201797-A1 (ES)
Title: Tone generator for PAM/TDM telecommunication system
IPC: H04Q1/44
Filed: 1981-02-21
Abstract: A tone generator for a telecommunication-especially telephone-system operating in the PAM/TDM mode comprises two complementary transistors with interconnected emitters joined to a "hot" conductor of a two-wire transmission path forming part of a trunk line between two groups of subscribers, the collectors of these transistors being connected through respective series resistors to a positive and a negative terminal of a DC source. These collectors are further coupled via respective shunt condensers to the "cold" conductor of the transmission path which is grounded through a low-ohmic further resistor. A local oscillator supplies a sinusoidal voltage wave through an operational amplifier to the interconnected bases of the two transistors whereby one or the other transistor conducts upon simultaneous closure, during a time slot assigned to a called subscriber, of a trunk switch at the near end and of a line switch at the far end of the transmission path enabling the resonant discharge of one of the previously charged shunt condensers into a remote line capacitor. Residual energy remaining stored on the parasitic capacitance of the two conductors is dissipated in a subsequent guard interval, upon the reopening of the two switches, as the partly discharged shunt condenser is recharged through the grounding resistor.

Title: Dot matrix printing apparatus.
IPC: G06K15/10
Filed: 1981-03-30
Abstract: Described, is a printing mechanism allowing full exploitation of the potential of dot matrix printing. Dot forming elements (7, 8) are mounted on a carrier (5) for transport past an array of hammers (6) located in front of media (2) to be marked upon. The dots (30) on carrier (5) are impacted by the hammers to form dots on the medium (1). By appropriate control of motion of the printing medium and timing of the hammer impacts, a dot may be formed anywhere on the surface of the medium. This allows unlimited character font set generation as well as special character printing for enlarged font, miniaturized font fast rough draft copy printing, the printing of ascenders and descenders for characters and for condensed or compacted printing. In addition, the mechanism permits an all points available graphics generation system and full control for variable vertical spacing of printed elements and of variable horizontal spacing of the printed elements. Variable print element shapes, grey tone graphics printing and multi-color additive or subtractive color processes are also facilitated.

Title: Drawing frame having at least one drawing region for the direct spinning of combed or semi-combed yarn.
IPC: D01H5/22
Filed: 1982-05-19
Abstract: A drawing frame with a drawing region or with two independent drawing regions includes, as a whole, four or more so-called drawing and control rollers. These latter all comprise pressure rollers with barrel rubbers. The control roller situated immediately upstream of the draw-off or "total" drawing roller is arranged in such a position that its periphery is separated from that of the drawing roller by a narrow gap. The ratios between the diameters and the speeds of rotation of these rollers is selected in such a way that the peripheral velocity of the "total" drawing roller is significantly greater than the peripheral velocity of the adjacent control roller. Consequently, an upwardly directed flow of air is created which removes the floating fibres which would otherwise tend to form windings or so-called "rolls".
