Title: Process and apparatus for preventing NOx emissions after emergency shutdowns of plants for the manufacture of nitric acid
IPC: C01B21/40
Filed: 1980-10-21
Abstract: The process and apparatus described seeks to prevent NOx emissions after an emergency shutdown in a process for manufacturing nitric acid by catalytic combustion of ammonia, compression of the nitrous combustion gases and subsequent absorption. Immediately on shutdown the intake nitrous gas supply to the compressor is interrupted, the residual intake side nitrous gases are conveyed to the delivery side, the delivery side gas volume is shut off, the gas on the delivery side is expanded to the intake side and then exhausted into a vacuum system. Subsequently the acid charged with NOx in the absorption stages is drawn off, degassed acid is circulated through the absorption stages until equilibrium is established, the pressure of the shutoff section is released and cooled acid is admitted to the absorption stages.

Patent ES-8301515-A1 (ES)
Title: Process for the dyeing in a gel state of fibrous articles of dry spun acrylonitrile polymers.
IPC: D01F11/06
Filed: 1981-07-10
Abstract: A dry-spun fibre material based on an acid-modified homopolymer or copolymer of acrylonitrile is advantageously dyeable with colour-fast results, following retroconversion into the gellike state by swelling with water, using soluble dyes which have in their molecule a plurality of groups, specifically more than one quaternary grouping and/or an uncharged strongly basic grouping, which act basic toward to the acid groups of the fibre substance. The chromophore of this colorant can come from the category of the monoazo or disazo dyes, the methine, azamethine or diazamethine dyes or the naphthalactam dyes. The dyeing of the regelled fibre is advantageously carried out continuously or batchwise from an aqueous dyebath, after the residual way-aqueous spinning solvent has been largely washed out the drawing of the fibres can take place before, during or immediately after the dyeing process. Owing to their special nature, the fast-dyeing dyes of the aforementioned type give optimum rates of fixation in the dyeing of PAC gel fibre, and do not cause any marked staining of machine parts and working baths, for example drawing or aftertreatment baths, due to leached dye in the subsequent production stages. Investigations of the fibre penetration, the rate of fixation and the resulting fastness properties, such as the wet fastness, did not reveal any disadvantages compared with conventional dyes.

Patent ES-8204901-A1 (ES)
Title: Television ghost cancellation system
IPC: H04N5/21
Filed: 1981-08-07
Abstract: A television ghost cancellation system is provided which includes a delay line having an input coupled to receive video signals which include a training signal component. The delay line provides a delay to the video signals which is substantially equal to the delay of the ghost of the training signal with respect to the training signal when a ghost signal is present. This delay causes a delayed training signal to appear at the output of the delay line at the same time that its ghost is applied to the input of the delay line. The delayed signal at the output of the delay line is applied to a control amplifier, which is coupled in a feedback loop with an amplitude comparator and a sample-and-hold circuit. The amplitude comparator compares the delayed training signal with the ghost at the input of the delay line and produces an error signal indicative of the amplitude differences between the two signals. The error signal is stored by the sample-and-hold circuit and is used to develop a control signal for the control amplifier so that the control amplifier will produce a pseudo-ghost signal which is of equal amplitude and opposite polarity as the training signal ghost during the sampling interval. The pseudo-ghost signal is combined with the original video signal to produce a deghosted output signal.

Patent ES-8402079-A1 (ES)
Title: Methods of flaw detection in billets
IPC: G01J5/00
Filed: 1982-11-02
Abstract: Cracks and surface flaws in billets are detected by heating the surface of the work-piece by means of high frequency current, the heating taking place while the work-piece is brought to pass in its longitudinal direction through a high frequency induction coil. That part of the work-piece, which has just left the coil is immediately, while the work-piece is still passing through the coil, scanned by means of infrared recording equipment which records the temperature distribution across the work-piece. The emission coefficient for the different work-pieces is increased and differences equalized by moistening the surface of the work-piece with an appropriate liquid, for instance water, to which have been added components for reduction of the surface tension.

Patent ES-8405157-A1 (ES)
Title: New devices and kits for immunological analysis.
IPC: G01N33/543
Filed: 1983-06-30
Abstract: The invention relates to new devices and kits for immuno-assays, especially solid-phase immuno-assays, comprising a solid porous support, preferably in the form of a sheet, where antigens or immunoglobulins, or both of them, are bound by direct application, with no other chemical or electrochemical treatment. The use of such supports makes possible to effect an unlimited number of antibody-antigen, reactions simultaneously and in one operation. The assays with these new kits are technically extremely simple in practice. The antigens or immunoglobulins on the solid support can be applied in any suitable pre-selected geometry, e.g. as an array of dots, preferably micro-dots, or lines. A preferred material for the solid support is nitrocellulose or nitrocellulose mixed with other cellulose esters. Before carrying out the immuno-assays residual adsorbing sites on the support must be saturated with whole serum of heterologous species to prevent nonspecific binding. The invention is also directed in particular to devices and kits treated in this manner, and, if desired, washed and dried. They can be stored for an indefinite time without loss of activity. In the immuno-assays to be carried out according to the present-invention the preferred detection system is the use of anti-primary species antibody coupled to peroxidase with a chromogenic substrate. The color intensity can be quantitated and calibrated with standards of known amounts of immunoglobulins bound to the same support. Densitometry permits the evaluation of the color reaction over a 1000-fold range of concentrations. The new kits can also be used with specific antibodies in a pre-determined array on the solid support for the detection of specific antigens and with complement proteins to detect antigen-antibody complexes.
