Patent ES-467477-A1 (ES)
Title: Fluid actuated operator and clutch linkage
IPC: F16D25/08
Filed: 1978-03-01
Abstract: A fluid actuated operator and linkage for a clutch. The linkage includes an operator link connected between the operator and a throwout bearing actuator arm. The operator includes an operator rod pivotally connected to the operator link and extending through an axial bore of a sleeve internal of the operator housing. The sleeve is connected for movement with the clutch pedal. The sleeve and operator rod form a valve for connecting a source of fluid under pressure to a pressure responsive means in the operator to generate a force to move the rod and disengage the clutch as the clutch pedal is depressed. As the clutch pedal is raised, the valve vents the fluid pressure responsive means to reduce the applied force which allows the clutch pressure springs to return the clutch to engagement. Embodiments are disclosed which have nonlinear characteristics which correspond to the force/displacement operating curves of certain types of clutches.

Patent ES-482236-A1 (ES)
Title: Vertical seismic exploration and profiling technique
IPC: G01V1/42
Filed: 1979-07-05
Abstract: In a vertical seismic exploration technique, periodic signals are emitted to propagate seismic waves in subsurface earth formations penetrated by a borehole. Seismic waves in formations near the bore hole are received at determined borehole depths and their representations recorded to form a vertical seismic profile. Exploration is conducted by recording representations of seismic waves at borehole depths varying by depth intervals ( DELTA X, Fig. 1B, not shown) corresponding to a time interval DELTA t dependent upon the wave period of a given mode. Profiling is accomplished by selecting recordings from borehole depths separated by this depth interval and combining using time delays related to the wave period and the propagation direction of the mode to produce traces E preferentially suppressing seismic waves propagating in one direction (1), (2) while automatically reinforcing those propagating in an opposite direction (3), (4). A vertical seismic profile is recorded, which may also utilize this time interval between traces. Use of depth and time intervals respectively approximating one- quarter of the wave length in the formation near the borehole and one- quarter of the recorded wave period of a selected propagation mode simplifies field production of the directionally preferential suppression and reinforcement characteristics of the resulting vertical seismic profile.

Patent ES-8106076-A1 (ES)
Title: Dynamoelectric machine having enhanced unbalanced stator current capability.
IPC: H02K19/16
Filed: 1980-08-29
Abstract: Surface currents are induced in dynamoelectric machine rotor body portions by negative sequence currents during unbalanced load operation. The surface currents are shunted away from retaining rings which are respectively situated on opposite axial ends of the rotor and function to restrain radial movement of conductor end turn portions which extend axially beyond the rotor's body portion. The retaining rings are shrink fitted on both ends of the rotor's body portion so as to structurally extend that body portion in both axial directions. Shunting the rotor surface currents away from the retaining rings provides an operating temperature therein of sufficiently low level to maintain high electrical joint integrity between the retaining ring and rotor. A mantle of highly conductive material surrounds both retaining rings in intimate electrical contact therewith. The mantle thickness is at least one-half depth of electrical current penetration for the rotor surface current's frequencies. The mantle is electrically connected to the rotor body portion preferably through interference fits with radial extensions of slot wedges which are situated in longitudinal slots formed in the rotor body radially outside electrical conductors disposed in those slots. The wedges constitute electrically conductive material and provide longitudinal electrical conductor retention in the rotor slots during high speed rotor rotation. Components joined through the interference fit include the mantle and the wedges' radial extensions. A material softer and of higher electrical conductivity than either of those joined components is preferably interposed as a plating material on either or both components.

Title: Process for removing nitrogen oxide gas.
IPC: B01D53/81
Filed: 1982-01-28
Abstract: In a process for reducing the NOx contents in waste gases, particularly waste gases from a nitric acid plant, by catalytic reduction of the NOx gases, a solution is to be provided, by means of which especially the nitrogen oxides content in waste gases can be reduced to the low values now demanded, without the catalyst used being irreversibly poisoned. This is achieved by carrying out the reduction in two stages, part of the NOx gas being dissolved out in a first stage by means of alkalis such as, for example, sodium hydroxide solution or sodium carbonate solution, and the remainder of NOx gas then being catalytically reduced to nitrogen in a second stage with addition of ammonia.

Title: Catalytic combustion engines.
IPC: F02P23/02
Filed: 1982-04-01
Abstract: A catalytic combustion engine, each cylinder of which has a pre-combustion chamber communicating through an inclined transfer cylinder to produce swirl around the chamber, and has a pair of spaced parallel or nearly-parallel catalytic screen elements, e.g. gauzes, mounted to both the mouth of the transfer passage and the fuel injector nozzle, so as to be clear of the circumferential swirl path of the gas circulating in the chamber. The minimum spacing between the two catalytic screens should exceed the width of the mouth of the transfer passage. The injector injects a fuel spray between the two catalytic screens which preferably just brushes each screen and impinges on a heater plug. The compression ratio may be much lower than that for a conventional Diesel engine, for example down to 12:1.

Title: Process for treating phosphided slags.
IPC: C21B3/06
Filed: 1982-05-21
Abstract: Process for the treatment of phosphuretted slag obtained by refining a molten bath, such as steel. The process according to the invention involves hot oxidizing the slag into which is blended, after refining, a pulverized solid adjuvant, strongly oxidizing and easily fusible upon contact with the slag. Among utilizable adjuvants, the carbonates of alkaline metals or alkaline earth metals are preferred, in particular sodium carbonate, which additionally, is a product currently utilized in the domain of the elaboration of metal, notably in iron metallurgy. The invention ensures a rapid passivation of the slag in stabilizing the phosphorus by forming phosphate and allowing in this manner the avoidance of the liberation of very toxic phosphenes which are produced naturally by cold hydrolysis.
