Patent ES-457671-A1 (ES)
Title: Pole claw member for a dynamo electric machine rotor
IPC: H02K1/24
Filed: 1977-04-06
Abstract: A method of manufacturing a pole claw member for a dynamo electric machine comprises in a first embodiment forming a serrated longitudinal edge in a ferrous strip and bending the serrated strip to form a cylinder with the serrations extending axially. The ends of the strip are then secured together by welding, rivetting or by a tang and aperture connection to produce a coronet form. The coronet form is then deformed in one or more, preferably three, die forming steps to produce the desired shape of claw and to define an annular base at the end of the cylinder.

Title: System and method for complete on line testing of a mechanical overspeed trip channel associated with an electrohydraulic emergency trip system for a turbine power plant
IPC: F01D21/00
Filed: 1977-04-21
Abstract: A system and method for complete on line testing of the emergency trip system of a turbine power plant is disclosed. The mechanical trip valve and a portion of a line to drain, of the emergency trip system, are isolated from the remaining portions thereof. The testing of the valve is permitted without an opening to drain of the line, which would cause a turbine trip. A three-way solenoid valve obstructs the line to isolate an upstream portion from a downstream portion while permitting introduction of fluid into the downstream portion at a pressure distinct from that in the isolated upstream portion. Pressure sensitive switches, which operate suitable indications are provided in fluid communication with both portions of the line to drain to sense the differential pressure therebetween upon operation of the solenoid valve and, subsequently, a rapid diminishing of pressure in the downstream portion indicative of a successful test of the mechanical trip valve.
Patent ES-461674-A1 (ES)
Title: Fuel system for compression ignition engine
IPC: F02D7/00
Filed: 1977-08-17
Abstract: A turbocharged diesel engine fuel system has its output fuel pressure varied upon acceleration as a direct function of the engine's manifold air pressure. The improvement of an orifice and chamber of predetermined size produces a delay in the transmission of the manifold air pressure signal to the fuel system. This, in turn, causes a delay in the increase of fuel rate to the engine thereby minimizing acceleration smoke without hurting engine power during steady state operation.

Title: Movable and extensible covering for large spans
IPC: E04B1/343
Filed: 1979-04-10
Abstract: A facility cover in the form of an extensible shed has movable arches that support a flexible canvas cover. The arches are modular and are connected in groups by diagonal elements hinged so as to form parallelograms with pantograph movement. The ends of the shed have at least one arch of reduced height so as to form an apse shape. Folding elements are provided on the sides of the shed that cooperate with the hinged parallelogram structure so as to assure that the cover folds outwardly in a bellows fashion as the arches are moved close to each other. As a result, the folding of the cover does not interfer with the movement of the arches.

Title: Treating of first material containing cellulose fiber
IPC: D21B1/14
Filed: 1979-09-18
Abstract: In the conversion of raw lignocellulose material into a fibre pulp, for papermaking, bleach is introduced while it is broken down into fibres by a screw press.

Title: Production of PVC irrigation pipe.
IPC: B29C48/32
Filed: 1982-10-21
Abstract: Process for producing flexible PVC irrigation pipe by extruding a plasticized PVC composition containing a melt strength-enhancing aid and a chemical blowing agent and (a) the extruded melt being expanded by foaming thereof immediately on leaving the die into a substantially closed-cell extrudate of outer diameter greater than the die orifice with the extrudate surfaces being substantially unpunctured, (b) drawing down the extrudate in the atmosphere causing rupturing of the foam cell walls of the extrudate to form a substantially open-cell extrudate having punctured surfaces, and (c) when the extrudate has been drawn down to a degree which is prior to any cellular collapse which would lead to the formation of water-impervious pipe, cooling the extrudate by passing it through a cooling means in order to prevent said collapse. Preferably the extrudate passes through a tubular guide into a water bath in step (c). The pipe thus produced is suitable for irrigation applications and may be used for long periods without exhibiting an unacceptable decrease in water-permeability.

Patent ES-8500526-A1 (ES)
Title: FIR Chrominance bandpass sampled data filter with internal decimation
IPC: H04N9/78
Filed: 1983-07-28
Abstract: A sampled data filter for separating chrominance signal from digitized composite video sampled at a 4fsc rate produces filtered sampled data chrominance signal at one half the input sample rate. The input video signal occurring as a 4fsc+I, +Q, -I, -Q sample sequence is decimated in the filter so that only the filtered replicas of the +I and +Q samples are computed. This effectively doubles the computational time permitted the filter circuitry without substantially compromising signal content.
Patent ES-8405564-A1 (ES)
Title: Phase relay for ac power transmission line protection.
IPC: H02H3/40
Filed: 1983-07-29
Abstract: A phase relay utilizes improved polarizing (VPOL) and operating signals (VOP) in order to provide discrimination between internal faults within a protected zone of an AC power transmission line and external faults that can appear as internal faults due to transients induced by capacitive voltage transformers or series capacitors. A zero sequence restraint signal is used to block operation of the phase relay on close-in single line to ground faults. A filter (76) is used in a by-pass circuit to attenuate high frequency transients which might delay, and possibly prevent a trip output on an internal fault. A high set by-pass circuit (72, 78), including zero suppression (72) to preclude an output on an external fault, is employed to provide faster operating times on severe internal faults. Forward offset and/or zero suppresion of the polarizing signal is used to reduce the characteristic timer setting and therefore increase the speed of the phase relay operation.

Patent ES-8604807-A1 (ES)
Title: Process for securely fixing a layer onto the edges of outer surfaces of planar moulded parts, such as car-door inner coverings
Filed: 1984-05-23
Abstract: In the manufacture of planar structures provided with layers such as, for example, car-door inner coverings, a problem arises in the secure fixing of the layer in the region of the edges of the surface. Hitherto, the edges were completely clasped using the layer in various working operations and/or manually. This is expensive. Simple folding, also carried out against the front side of the edges, is insufficiently durable. Therefore, it is proposed according to the invention to place the layer inside the mould in a first operation of folding against a front side of the edge of the surface and then to apply it in an additional folding operation to the additional outer surface which follows the front side of the edge of the surface, this folding having to take place inside the mould by means of two independent deformation elements which can be transferred in a corresponding manner.

Patent ES-8802268-A1 (ES)
Title: Lubrication dispensing system in a movable cotton harvester
IPC: A01D/
Filed: 1985-09-06
Abstract: A simple constant displacement pump provides pressurized lubricant from a grease tank mounted on the vehicle, via a two-position valve, to a selected group of distribution pipes mounted on a cotton harvester. Each distribution pipe of the group is connected to a plurality of conduits which lead to plant row unit lubrication points of the harvester, such as the cam tracks of the gathering bar, gathering drum actuating gears and lubricant cavity for each one of the collecting drum bars. The amount of lubricant for each point is determined principally by the relative resistance of the conduit which is in turn controlled by the length and transverse section of said conduit, such that, in this way, the metering valves or pumps for each lubrication point are eliminated. There are conduits which have substantially identical lengths and transverse section, for each group of points which have to receive identical amounts of lubricant. There are two groups of distributor pipes available for each pair of row units which are, in turn, charged with lubricant under the control of the selector valve.
