Patent ES-374487-A1 (ES)
Title: Submerged-welding method
IPC: B23K9/18
Filed: 1969-12-12
Abstract: In flux-submerged arc welding using a consumable wire electrode the voltage drop between the electrode and workpiece is maintained at such a low value that the positive column region of the arc substantially fails to exist and the welding current is maintained at a value greater than 1000 amps. It is stated that the arc normally comprises three regions, viz. anode drop (the region adjacent the anode), cathode drop (the region adjacent the cathode), and positive column (the region between the anode and cathode drops). The voltage drop over the anode and cathode drops together is stated to be about 22 Volts in submerged arc welding and has only small dependence on current strength. Hence, the welding voltage is set in the region 22-24 Volts in dependence on current strength for currents between 1000 and 4000 amps, and as a result the positive column region is substantially eliminated. Greatly increased welding rates are stated to be obtainable in such conditions. Preferably the diameter of electrode is 6 to 8 mm. for currents in the range 1000-2500 amps, and at least 7À0 mm. for currents in excess of 2500 amps. Preferably, also, the length of the electrode between the current input and its tip is less than 35 mm., and a constant voltage/ current source is used which obviates the need to control the wire feed. A welding rate of 300 cm./min. is referred to.

Title: Method of reducing the coercive force of permanent-magnetisable material
IPC: H01F1/055
Filed: 1970-03-12
Abstract: Magnetic bodies are obtained by compacting, before, after or during magnetization, a powdered rare-earth-cobalt compound of the formula M 5 R where M=Co or a combination of Co with one or more of Fe, Ni and Cu and R is one, or more lanthanide, yttrium or thorium. The material is reduced in coercivity by application of a pressure of hydrogen gas until it contains at least 0À2 moles per mole of M 5 R before magnetization. ,In an example SmCo 5 is pulverized, orientated in a magnetic field, compressed without a binder to form a block and the block was subjected to a hydrogen pressure of 30 atmospheres, and magnetized.

Abstract: A multi-band receiving antenna is supported on a windowpane for a radio-receiving set having a single antenna input socket. The antenna has a fishpole-type section which principally contributes to the reception of the metric wave band. A frame section, which runs parallel to the rim of the windowpane, principally contributes to the reception of the medium wave band. Each of the two sections contributes furthermore in a substantial measure, in the order of 10 - 20%, to the reception of signals having a frequency included in the band which is principally received by the other section. The impedance of the metric wave section is adapted by a spirally formed arrangement of the conductor or conductors of the frame portion of the antenna starting from the antenna terminal. The spiral forms an inductance of 0.2 - 0.5 mu H over an area of 5 - 15 cm2. The medium wave section includes a single conductor which runs in close proximity to the rim of the pane or two conductors which run in different directions along portions of the rim. When two conductors are used, the spiral is formed of a double wire.

Title: Method of combusting nitrogen-containing fuels
IPC: F23C99/00
Filed: 1976-12-28
Abstract: A method for combusting nitrogen-containing fuel by: combusting a first fuel-air mixture in the presence of a catalyst in a first stage, operated fuel-rich so that the amount of air in the first stage is substantially less than the amount needed for complete combustion adding additional air to the effluent gas from the first stage to form a second mixture with an amount of air at least sufficient to combust fully the effluent from the first stage and then combusting the second mixture in a second stage. The first mixture is sufficiently fuel-rich, and the second mixture contains sufficient additional air, so that the combustion temperature in the first stage is below a temperature that would result in any substantial formation of oxides of nitrogen or other fixed nitrogen compounds from atmospheric nitrogen present in the mixture being combusted, and the second stage temperature also is below that for substantial nitrogen oxide formation therefrom. The method serves to suppress formation of nitrogen oxides from the nitrogen-containing compounds in the fuel.

Title: Automatic breaker for intermediate portion to venous staying cannula and catheter and wasteful cannula
IPC: A61M5/31
Filed: 1978-03-31
Abstract: Closing devide for the nozzles and small tubes of injection and blood-sampling appts. comprises a highly elastic membrane with a number of incised slits. In the rest position the membrane prevents an effusion of blood out of the nozzle inserted in a vein or from a tube remaining in a vein or of a catheter inserted in a blood vessel. The membrane with the slits, is fixed in the connecting sleeve by the piece made from a synthetic material. The part contains the receiving cone of the connecting pieces. The membrane is perforated by means of a system of slits e.g. one rectilinear slit in the middle, two slits in the form of a cross or three slits spaced 60 degrees from each other. The cone is pushed down and dilates the system of slits so that liq. can pass both ways. After removal of the cone the membrane relaxes and closes the slits sufficiently well when a tube or a catheter is being left in a vein. Device is suitable both for injections and for the removal of blood. There is no notable resistance in the circuit so blood samples can be taken without risk or damage to the red cells. The connecting pieces can be removed repeatedly, or withdrawn for a time while a bed is re-made, thus increasing the liberty of the patient.

Title: Controlling the injection of ammonia in a dry type exhaust gas denitration process
IPC: B01D53/74
Filed: 1979-01-23
Abstract: In a first processor unit the relationship between the amount of nitrogen oxides in a combustion exhaust gas and a numerical value representing an amount of combustion, e.g. - fuel flow rate or the like, is stored. In a second processor unit the ratio of ammonia to nitrogen oxides as a function of the combustion exhaust gas temperature is stored. A numerical value corresponding to the actual measured amount of combustion is inputted to the first processor unit to derive the amount of nitrogen oxides in the combustion exhaust gas. The actual measured combustion exhaust gas temperature is inputted to the second processor unit to derive the ratio of ammonia to nitrogen oxides. The optimum amount of ammonia to be injected is derived by multiplying the amount of nitrogen oxides, derived by means of the first processor unit, by the ratio of ammonia to nitrogen oxides derived by means of the second processor unit. In a preferable embodiment of the present invention, the ratio of ammonia to nitrogen oxides is corrected before the multiplication by means of a correction factor which is stored in a third processor unit and which corresponds to a time variation rate of the combustion exhaust gas temperature.

Title: Controlled protein fractionation.
IPC: C07K14/00
Filed: 1980-05-02
Abstract: A controlled protein fractionation method in which a cold protein-containing solution is circulated in contact with one side of a membrane and the temperature is controlled by circulating a protein precipitant solution in contact with the opposite side of the membrane. The flow rate is increased and back pressure is exerted on the precipitant solution to cause it to penetrate the membrane, mix with the protein solution and precipitate protein in fine particles along an inside membrane wall. The precipitated protein may be concentrated and separated by centrifugation or diafiltration. The membrane is preferably in the form of a plurality of hollow fibers. Control of process variables increases yield and purity, decreases processing time and reduces degree of denaturization.

Also, the real time at which the transition occurred is placed in a capture-time holding register. The contents of the input holding and capture-time holding registers are repetitively placed in a stack as pending input data bytes. The pending input data bytes are accessible to the computer central processing unit, as required by the program, via the memory/address bus.
