Patent ES-435439-A1 (ES)
Title: Stratified charge engine
IPC: F02B75/02
Filed: 1975-03-08
Abstract: An apparatus for applying a stratified charge to a reciprocating internal combustion engine is disclosed. The apparatus comprises a cylindrical rotary valve body disposed for rotation within the head of an internal combustion engine. The valve body defines diametrically extending inlet and exhaust passages which, during rotation of the valve body, place a cylinder of the engine in sequential communication with an inlet manifold and an exhaust manifold secured to the head. The inlet manifold comprises a double-passage gallery for transporting a lean fuel/air charge in a first passage and a rich fuel/air charge in a second passage. Rotation of the inlet passage into communication with the cylinder also brings the inlet passage into sequential communication with the first throat and then the second throat for transporting the first lean charge and then the second rich charge to the cylinder. Means are also provided for shielding the exhaust passages from excessive exhaust heat for sealing the rotary valve body and for controlling the timing of the valve in response to engine demand.
Patent ES-435548-A1 (ES)
Title: Apparatus for crimping yarn
IPC: D02G1/12
Filed: 1975-03-12
Abstract: Apparatus and method for stuffer box crimping yarn is disclosed in which continuous filament drawn yarn having a thermoplastic component and varying in denier along its length is treated in the same crimping area and where that portion of the yarn of higher denier is texturized to a lesser extent than that portion of the yarn of lower denier. The apparatus for carrying out the method provides a crimp site and a very short plug guiding area which establishes the lateral width of the plug. A pair of pressure shoes are oppositely disposed on either side of the plug of crimped yarn as it leaves the guiding area. The shoes are spaced apart at a slightly greater distance than the width of the guiding area to provide voids along the plug sides thereby reducing if not eliminating back pressure in the plug due to lateral plug contact above the guiding area and are pivoted adjacent the guiding area, and apply a uniform pressure on opposite sides of the plug downstream of the guiding area where they converge against the plug. Means for relaxing the plug of yarn fore and aft of its axis are provided intermediate the crimping site and the downstream ends of the pressure shoes. A gathering area downstream of the pressure ends of the shoes is designed to have little or no effect upon the yarn entering and leaving it, and in this respect, it provides further means for yarn plug relaxation.

Title: Deflection waveform correction signal generator
IPC: H04N3/233
Filed: 1975-09-26
Abstract: Cascaded multipliers are coupled to a source providing a periodic sawtooth deflection waveform, the amplitude of which varies with variations in the high voltage applied to an accelerating anode of a kinescope. The sawtooth signal is cubed by the cascaded multipliers and multiplied by the inverse square of a voltage which varies with changes in the kinescope anode potential. The system thus incorporates S-correction and means for correcting the deflection waveform to compensate for changes in the high voltage supplied to the kinescope anode.

Title: Production of improved chromium oxide green pigment
IPC: C01G37/033
Filed: 1976-02-13
Abstract: A process for the production of chromium oxide green pigment comprising heating a mixture of ammonium dichromate with at least the stoichiometrically equivalent quantity of a sodium salt selected from the group consisting of chloride and sulfate over a period of at most about 15 minutes to a pigment-forming temperature of about 800 to 1100 DEG C in the presence of about 1 to 45% water based on the weight of the mixture, calcining the mixture at a temperature in the above-mentioned range, and separating the formed pigment from the salts. The mixture may be formed in situ by reaction of sodium dichromate with ammonium chloride or sulfate in the presence of water.

Patent ES-8102280-A1 (ES)
Title: Thermal-power plant fed by a geothermal heat source.
IPC: F03G7/04
Filed: 1980-06-25
Abstract: The invention concerns a thermo-electric power station, supplied by a geothermal heat source, involving the use of at least two fluids. The first fluid (water) makes it possible to transfer the geothermal energy from the subsoil to the power station. The fluid is pumped into the subsoil through a downcast shaft (29, 33) and returns, after being heated to a pre-established temperature, via an outlet shaft (28, 32). The second fluid is carbon dioxide, which, through direct contact with the first fluid, absorbs the latter's thermal energy and transforms it into mechanical energy via successive machines (7, 8, 9). A possible third fluid (ammonia) produces, in an absorption refrigerator plant (2), the refrigeration necessary for lowering the temperature and, therefore, the pressure of the second fluid when it leaves the last machine (9), thus making possible the pre-established optimal pressure stage.
