Title: Circuit arrangement for centrally controlled telephone exchange installations
IPC: H04M11/00
Filed: 1968-11-21
Abstract: A circuit arrangement for centrally controlled long distance telephone exchange installations, wherein central information transmission circuits are provided between central control means and centrally controlled individual apparatus. The latter may, for example, comprise internal connection sets, long distance line repeaters, exchange office repeaters in subscriber installations with extension stations, registers, dial receivers and the like in which connections of the centrally controlled individual apparatuses to the information transmission circuits are jointly controlled. In the centrally controlled exchange installation, there is provided between the central control mechanism and the centrally controlled individual apparatus, at the location of the latter, a common connection mechanism which receives connection commands through the address informaton from the central control mechanism. The common connection mechanism controls the connection of the individual apparatus to information lines over connection circuits.
Patent ES-360544-A1 (ES)
Title: Textured textile material
IPC: D02G1/00
Filed: 1968-11-22
Abstract: A monofilament, thermoplastic, e.g. nylon, yarn is textured by flattening selected portions (20-62 per linear inch) of the heat softened, previously drawn yarn so as to form segments of altered cross-sectional shape in the yarn in a uniform pattern whereby the yarn exhibits a variation in bending modules along the length thereof. The pressure and temperature of such treatment are so controlled as to effect permanent distortion of the yarn while maintaining a residual shrinkage of at least 5% in the flattened yarn. The latter is cooled whilst maintained in tensionless condition and the textured yarn is wound into a package under a controlled tension which prevents any further drawing thereof. As shown, a sheet 13 of monofilaments passes from a beam 11, through a reed 15, between one or more pairs of rolls, as at 19, 21, one roll driven and having a grooved surface to effect flattening of the monofilaments at intervals and the other roll smooth-surfaced, one or both rolls being heated internally as by circulating oil. Take-up rolls 25, 27 may effect positive filament cooling prior to package formation. In a knitted fabric comprising textured yarns combined with untextured yarns, effects, e.g. crepe, may be caused by a loop distortion produced during the knitting cycle due to the varying bending modules.

Abstract: A power unit comprises a resonator having a mouth located in the sea and containing a body of water and an air cushion above the body of water. This resonator can have a neck defining a relatively small flow area compared with the surface area of the body of water immediately below the cushion. The air cushion is controlled by pressure sensor 35.1 and reversible compressor 35.3 to cause the water to resonate in response to pressure fluctuations resulting from wave motions in the sea, thereby developing fluctuations of increased pressure. The unit is constructed so that the increased pressure fluctuations create a fluid flow through an outlet 40 and tank 38 to drive a turbine 48 driving an alternator 50. Again, the resonator is used to drive a ship, the flow through outlet 40 being fed to a jet nozzle, or reversible vanes being provided at the mouth 32 of an otherwise closed resonator.

Title: Electrostatically removing particulate material from gas
IPC: B03C3/12
Filed: 1979-03-01
Abstract: An apparatus for reducing back corona effects while charging high resistivity dust or the like in a corona field, includes a corona discharge electrode 20, a passive electrode 18 and a screen electrode 17, the screen electrode being positioned between the discharge electrode and the passive electrode. The screen electrode is positioned more closely to the passive electrode than to the discharge electrode and is supplied with an electrical potential which is of the same polarity as and a fraction of the magnitude of the discharge electrode potential relative to the passive electrode. Gas having entrained therein the particulate material, which is to be removed, flows between the screen and discharge electrode and thence to a particulate material collection stage 30. The space between the screen and corona discharge electrode remains essentially a unipolar ion field, while ions of the opposite polarity originating at the passive electrode due to back corona are collected by the screen electrode. Instead of the cylindrical geometry shown, a parallel plate/wire arrangement may be used.

Title: Enhancement of lowest order mode operation in nonplanar DH injection lasers
IPC: B65D53/00
Filed: 1979-11-27
Abstract: By employing a channel in the substrate of a GaAs-GaAlAs injection laser, the active waveguiding layer of the laser can be made to have constricted regions above the shoulders of the substrate channel.

Patent ES-488545-A1 (ES)
Title: Power steering valve and method of making the same
IPC: B23C3/30
Filed: 1980-02-13
Abstract: An improved power steering valve has a sleeve which circumscribes an inner valve member. An end mill or other rotary cutting tool is utilized to form axially extending grooves inside the valve sleeve. When the end mill is forming the grooves inside the valve sleeve, the axis of rotation of the end mill extends at an acute angle relative to the central axis of the valve sleeve. This results in a groove being formed with axially sloping end surfaces. In order to tend to maximize the compactness of the construction of the valve sleeve, fluid passages or holes are drilled along a sloping path from annular grooves on the outside of the valve sleeve to the sloping end surfaces of the axial grooves inside the valve sleeve. In addition, the compact construction of the valve sleeve is further promoted by forming some of the annular grooves with sloping bottom surfaces so that these grooves are relatively deep. This enables the width of these grooves to be reduced without reducing the capacity of these grooves to accommodate fluid flow.
