Patent ES-306039-A1 (ES)
Title: Filtration cell
IPC: G21F5/00
Filed: 1964-11-14
Abstract: A filtration cell (Fig. 1), particularly for filtration of gases containing radio-active material, comprises a two-part container 2, 4 in which a filter element 22 is secured by a latching device 24, which consists of balls 42 radially movable in holes through sleeve 38 to engage in groove 46 of extension 34 of the filter element, the balls being able to move outwards to decouple element 22 from part 4 of the container when operating member 48, 50, 58, urged downwards by a spring 52, is pushed upwards by cylindrical extension 58 engaging part of a transfer can (Fig. 2, not shown) for receiving a contaminated filter element. In Fig. 1, the elenent 22, of sintered stainless steel, is coupled to part 4, but the width of groove 46 permits some vertical movement, and spring 62 urges inlet nozzle 26 of the element into sealing contact with gas supply nozzle 14. To change element 22, valves on inlet and outlet pipes 12, 16 are closed and the cell flushed with clean gas and reduced to atmospheric pressure. Twopart clamping collar 6 is released and part 4 with element 22 lifted and subsequently lowered into shielded transfer can (64), (66) (Fig. 2). With plate (74) of the can lowered element 22 is released, when extension 58 is raised by contact with step (70), and falls on to plate (74). Part 4 is lifted and lowered into another can, containing a new filter element 22 on a plate (74) locked in its raised position (Fig. 3, not shown). Extension 34 of the element then enters the sleeve 38, and subsequent lifting of part 4 permits relative downward movement of extension 58 and forces balls 42 inwards to lock on the new element.

Patent ES-373683-A1 (ES)
Title: Hop extracts
IPC: C12C7/00
Filed: 1969-11-19
Abstract: In preparing bittering adjuncts for beer involving (a) preparing a solvent extract of hops containing the hop resins and oils, (b) separating the extract into an [alpha]-acid-containing fraction, which is substantially free from #-acids and hop oils, and a #-acid- and oil-containing fraction which is substantially free from [alpha]-acids, and (c) isomerizing the [alpha]-acid-containing fraction, xanthohumols are separated from the solvent extract of hops prepared in step (a) before proceeding to step (b). Thus, a benzene extract of hops is taken up in petroleum ether and the xanthohumols are extracted with 70-80% v./v. of aqueous methanol at a pH insufficiently high to extract the [alpha]-acids also. The methanolic extract yields a resinous residue rich in xanthohumols. It is stated that xanthohumols and isoxanthohumols, being insoluble in both hydrocarbon and aqueous alkali would entrain a significant proportion of the valuable [alpha]-acids during the solvent extraction process. Part of the xanthohumol then remains in the extract and tends to cause cloudiness on addition to beer. The isomerized extract resulting from step (c) typically contains 10-70% by weight of iso-[alpha]-acids as their salts, less than 0À2% of xanthohumols and 20-85% of water. Specifications 1,161,787 and 187,789 are referred to.

Title: Analytical photometer with means for measuring,holding and transferring discrete liquid volumes and method of use thereof
IPC: G01N35/00
Filed: 1970-02-25
Abstract: A photo-metric solution analyzer includes a rotor assembly 1 having radially orientated cavities 10, 11, 12 disposed in an annular array and syphons 13, 14, 15 communicating with each of the cavities, and further includes means (not shown) to activate the syphons whereby the cavities are emptied. When the assembly 1 rotates a stationary tube 24 dispenses liquid into a central chamber 25 with a serrated periphery 26, whereby the liquid is introduced uniformly into first cavities 10. An overflow pipe 27 controls the amount of liquid in the cavities 10. A burst of compressed air from the chamber 25 causes the liquid to flow through first syphons 13 into second cavities 11. Additional liquids may similarly be introduced one at a time into the second cavities to form a mixture with the original liquid. A burst of compressed air from header 16 activiates second syphons 14 through which the liquid or mixture is transferred to third cavities 12, where its transmittance is measured by passing a beam of light through holes 21, transparent plates 4 and 3, and the transparent disc 5 in which the syphons and cavities are formed. Mixing of liquids may be facilitated by reducing the pressure in the header 17 to cause bubbles to pass through the mixture in the third cavities 12 from third syphons 15. A final burst of compressed air from header 17 activates the syphons 15 through which the liquid or mixture passes into a stationary waste trough 19 surrounding the assembly 1.

Title: Electric primary cell comprising a visual indicator of its state of charge
IPC: H01M6/50
Filed: 1975-10-31
Abstract: Alkaline electrolyte electric primary cell comprising a visual indicator of its state of charge, the said primary cell having a negative electrode basically containing zinc powder in contact with its outside casing. The said charge indicator is constituted by a perforated copper or copper alloy sheet which is visible from the outside of the primary cell and is in contact with the negative mass. On assembly, the copper sheet becomes coated with a film of zinc and appears to have a grey color. During cell discharge the zinc of this film oxidizes and the original coloration of the sheet comes visible through a transparency provided in at least a portion of the casing. The sheet may be located at any selected depth in the thickness of the negative electrode and the time of restoration of original coloration is a function of the location depth and thus indicative of the residual state of charge.

Title: Inorganic pigment comprising a solid solution of differing spinels
IPC: C01G23/00
Filed: 1977-08-18
Abstract: An inorganic pigment and its process of manufacture are disclosed, characterized in that the pigment, in contrast to substitution of one or more metal ions into a given spinel crystal structure, is a solid solution comprising at least a double spinel structure, that is, a first cubic spinel crystal structure containing within such lattice the spinel-forming metal oxides of at least a second, differing spinel. As a result, the present inorganic multiple spinel solid solution pigments can be varied over a wide range of compositional make-up and yet, conversely, easily adjust to even slight compositional changes by varying the amounts or components of the first spinel and/or the spinel-forming metal oxides. The resulting pigments correspondingly can produce a wide range of colors and are yet capable of even small nuances of changes in color.
Patent ES-462877-A1 (ES)
Title: Frequency modulated single point fuel injection circuit with duty cycle modulation
IPC: F02D41/04
Filed: 1977-10-04
Abstract: A frequency modulated control circuit for an electronic fuel injection system to control the pulse-type injection of fuel at a single point of the fuel intake of an internal combustion engine in accordance with the derived mass air flow rate into the engine comprising a pressure sensor for sensing the manifold pressure of the internal combustion engine, and an engine speed sensor, both of which generate an analog signal which are multiplied by a multiplier circuit to provide a signal representative of the mass air flow to the engine. The multiplier circuit includes a separate control input for varying the output signal level of the multiplier circuit by a preselected factor determined by the final output of the control circuit. The output of the multiplier circuit is fed to a voltage controlled oscillator to produce an output signal taking the form of a pulse train, the frequency of which varies with the amplitude of the mass air flow signal. The output of the voltage controlled oscillator is fed to a pulse generator which generates a fixed on-time pulse for each pulse in the pulse train being fed from the voltage controlled oscillator. The output of the pulse generator is sensed by a duty cycle switch which senses when the output frequency of the voltage controlled oscillator results in a high duty cycle for the output pulses. In this high duty cycle situation, the output analog signal of the multiplier is reduced by a preselected fraction. The duty cycle switch also generates an output signal which varies the duration of the pulse output from the pulse generator as a reciprocal of the variation being applied to the multiplier from the duty cycle switch or enable a secondary injector.
