Patent ES-419941-A1 (ES)
Title: Process for the removal of particulate matter and acidic gases from carrier gases
IPC: B01D53/34
Filed: 1973-10-25
Abstract: A process is disclosed for the removal of particulate matter and acidic gases such as sulfur dioxide from a carrier gas in which the carrier gas is driven through an elongate mixing tube by a steam ejector and mechanically atomized water is introduced into the outer region of the jet of steam emerging from the nozzle of the steam ejector. The mechanically atomized water is further atomized by the shearing action of the steam jet to form high velocity droplets which are intimately and turbulently mixed with the carrier gas so that the particulate matter in the carrier gas becomes entrained with the water droplets. The flow of the turbulent mixture of steam, carrier gas and water droplets through the mixing tube is regulated to provide a retention time in the mixing tube so that the water droplets containing the particulate matter grow to a size sufficient to permit separation of the drops by centrifugal means. If it is desired to remove sulfur dioxide or other acidic gases from the carrier gas in addition to the particulate matter, an alakaline reagent is introduced into the water prior to the mechanical atomization of the water whereby the further atomized high-velocity water droplets will contain the alkaline reagent. The flow of the turbulent mixture in the mixing tube is regulated to provide sufficient time for the alkaline reagent to react with the acidic gases and form aqueous droplets of sulfur reaction products, for the aqueous droplets to entrain the particulate matter from the carrier gas, and for the aqueous droplets to grow to a size sufficient to permit separation of the droplets by centrifugal means.

Title: Drain devices in hydraulic control circuits
IPC: F16K3/00
Filed: 1975-03-13
Abstract: The invention relates to drain devices in hydraulic control circuits, particularly for hydraulic ultrarapid release control of a circuit breaker.

Title: Method of making a trim strip
IPC: B29C48/21
Filed: 1977-05-26
Abstract: The disclosure relates to a method of making a trim strip comprising the extrusion of a vinyl material to form a body which is so shaped that it can be confined in a peripheral slot in a roll, thereby to permit substantial pressure to be applied on the extruded body and a decorative strip by a mating roll. The top portion of the extruded body has side extensions which are supported by the edges of the recessed roll thus, substantial pressure can be applied on the entire top of the decorative surface strip and the body to produce an adhesive bond or a bond by heat sealing. After the body is cooled, it is advanced through a number of aligned milling cutters to machine aligned recesses in the sides of the body to produce a retention cutout. After being machined to depth, the trim strip is advanced through a pair of grinding wheels to accurately form and space the recesses. During the extruding operation, a coated wire may be embedded within the body in the conventional manner.

Patent ES-8100495-A1 (ES)
Title: Method of fabricating high strength optical preforms
IPC: G02B6/036
Filed: 1979-10-05
Abstract: A process is disclosed for finishing high-strength multilayer optical preforms capable of being drawn into long optical fibers useful for light-wave communications. The preforms are of the type prepared by sequential chemical-vapor-deposition of the various desired glass layers within a tubular glass substrate that is then collapsed into a solid cylindrical preform comprising a cylindrical light-transmitting core surrounded by a concentric cladding layer and one or more additional layers within the collapsed substrate. In order for the outermost deposited additional layer to constitute a thin high-compression layer on the surface of the completed optical structure, it is necessary first to remove substantially all of the substrate layer from the preform in such a manner as to leave the adjoining high-compression layer intact. This is accomplished by selecting a glass for the substrate layer that is capable of being etched away faster than the high-compression layer, and then using controlled preferential etching to remove the substrate layer without penetrating or damaging the high-compression layer. This method makes it possible to provide a thinner and more effective outer high-compression layer, on the surface of the completed preform, which is of uniform radial thickness regardless of any nonlinearity or non-concentricity of the core, enclosing layers, or substrate layer. An optical fiber drawn from the completed preform will then retain a uniform high-compressive stress in its outer layer that contributes materially to its tensile strength, durability, and fiber life.

The valve element is biased to a closed position by a spring and it controls flow along a path from the chamber to the inlet. The flow path also incorporates a non-return valve. The valve element is set to lift from its seating at a pressure which is greater than the residual pressure in the inlet plus the pressure required to open the non-return valve.

Title: Adjustable and selective electrical filters and methods of tuning them.
IPC: H03H11/04
Filed: 1981-02-09
Abstract: A notch filter is provided with an ancillary circuit including a non-inverting amplifier and a coupling which enables the filter to form part of an oscillatory loop of which the frequency of oscillation corresponds to the frequency of maximum rejection by the notch filter. Measurement of that frequency facilitates the tuning of the notch filter, which includes capacitors constituted by varactor diodes. The gain of the ancillary circuit may be adjusted to change its mode of operation from oscillation to that of a tuned amplifier so that a sweep of the center frequency of the notch filter through a range of interest facilitates a search for an unknown interfering frequency and the simultaneous tuning of the notch filter to reject that interference.

Patent ES-8204802-A1 (ES)
Title: Fuel injection pumping apparatus
IPC: F02M41/14
Filed: 1981-07-22
Abstract: A fuel injection pumping apparatus comprises an axially movable distributor member the axial setting of which determines the amount of fuel supplied by the apparatus at each pumping stroke. The distributor member is biassed by a spring in one axial direction and is movable in the opposite direction by varying the fluid pressure in a chamber through a port. The port is formed in a sleeve which is coupled to the distributor member by means of a lever and a rod member is axially movable within the sleeve. The axial position of the rod member can be varied to alter the effective size of the port and the distributor member and sleeve move because of the change in pressure in the space. A new equilibrium position is thus established with the distributor member following the movement of the rod member.
