Patent ES-419119-A1 (ES)
Title: Torch nozzle orientation for internal combustion engine
IPC: F02B75/02
Filed: 1973-09-27
Abstract: A four-cycle internal combustion engine employs a main combustion chamber supplied with a lean combustible mixture and an auxiliary combustion chamber supplied with a rich combustible mixture. A torch nozzle restriction connects the chambers. A spark plug is associated with the auxiliary chamber. A thin wall heat resistant cup spaced from the engine walls forms the auxiliary chamber and the cup is provided with apertures communicating with the main chamber and the spark plug. The main chamber is non-symmetrical and has its greatest depth between the torch nozzle restriction and the axis of the cylinder bore in which the piston reciprocates. The direction of the principal axis of the torch flame through the restriction is toward the center of mass of the air-fuel mixture in the main chamber when the piston is 90 DEG past top dead center.

Patent ES-432248-A1 (ES)
Title: Steam generator
IPC: F22B1/16
Filed: 1974-11-25
Abstract: A pressurized-water reactor steam generator has a preheater surrounding the cold leg of its U-tube bundle heat exchanger, the preheater discharging being separated by a horizontal partition into upper and lower sections which are each connected with its own feed-water inlet and which respectively discharge the preheated feed water upwardly and downwardly. When the generator is operated under low-load conditions, the feed water supplies are cut off from the two preheater sections, resulting in possible boiling of the water in the preheater because of the lack of circulation through the preheater. To prevent such boiling, means are provided for interconnecting the two preheater sections in series, around the horizontal partition, so that feed water can by thermal action circulate upwardly through the preheater, bypassing its partition, the water entering what would normally be the downwardly discharging outlet of the preheater and going upwardly, bypassing the partition and upwardly through the preheater's upper section so as to be discharged upwardly.
Patent ES-442768-A1 (ES)
Title: Squelch circuit for a video record player
IPC: H04N5/91
Filed: 1975-11-18
Abstract: In a video disc player, a first FM signal recovered from the disc is subject to frequency demodulation to obtain a composite color video signal, and a second FM signal recovered from the disc is also demodulated to obtain an accompanying sound signal. The player includes a defect detector, monitoring the first FM signal to identify carrier frequency departures from the intended deviation range, and switching apparatus for effecting a substitution of stored video signals, in replacement of the output of the video FM detector, when the defect detector identifies such departures. A squelch control signal generator is rendered responsive to an output of the defect detector, and develops a squelch signal when the defect indication persists beyond a predetermined minimum length of time. The squelch signal is employed to inhibit the passage of sound and video signals to player output terminals. The squelch control signal generator is additionally rendered responsive to player apparatus controlling placement of the player stylus in and out of playback position (e.g., controlling lowering/lifting of stylus arm), so that removal of stylus from playback position initiates squelch signal development without need for passage of said predetermined minimum length of time.
Patent ES-444232-A1 (ES)
Title: Electrostatic position-measuring transducer
IPC: H03M1/64
Filed: 1976-01-12
Abstract: Two relatively movable, spaced elements having electrostatically coupled sets of uniformly spaced interdigitated electrodes form a precision, high gain linear or angular position-measuring transducer. Coupling electrodes on one element capacitively couple to portions of the electrodes on the other element so that electrical connections to external excitation and detection circuitry need be made to only one of the two elements. The shape and dimensions of the electrodes can be arranged to reduce or eliminate undesired impedance variations, capacitive coupling and unwanted harmonic coupling wave frequency components.
