Abstract: "PROCESSOS DE CULTURA DE CéLULAS DE MAMìFERO PARA A PRODUçãO DE PROTEìNA". A presente invenção descreve métodos e processos para a produção de proteínas, particularmente glicoproteínas, através de cultura de células de mamífero ou de células de animais, de preferência, mas não limitados, à cultura de células com lote de alimentação. Em um aspecto, os métodos compreendem pelo menos dois desvios de temperatura realizados durante um período de cultura, no qual a temperatura é menor ao final de um período de cultura do que no período inicial de cultura das células. Durante toda sua duração, os processos de cultura da invenção envolvendo dois ou mais desvios decrescentes na temperatura sustentam a alta viabilidade das células cultivadas e podem proporcionar uma titulação final aumentada de produto de proteína e uma alta qualidade de produto de proteína, conforme determinado, por exemplo, pelo teor de ácido siálico da proteína produzida. Em outro aspecto, os métodos compreendem a adição retardada de um composto polianiónico durante um período de cultura. A adição retardada de composto polianiónico sustenta a alta viabilidade das células cultivadas e pode ampliar a fase de crescimento, retardar o início da fase de morte e impedir a fase de morte.

Abstract: The laminations of a laminated stator of a slowly running electrical machine having a high number of poles are composed of grain-oriented sheets, each of which has a preferential magnetic direction that extends substantially longitudinally along the teeth of that sheet. This permits the excitation current to be reduced, and, as a result, the air gap of the machine can be enlarged so that, on the whole, approximately the same excitation is required as for a laminated stator in which the laminations consist of normal, non-oriented sheets. As a result, the mechanical stability of the machine is increased. The invention is especially useful in asynchronous tube generators.

Abstract: Two permeable-to-gas patterns [68] form an inner cavity [54] of desirable configuration and are enclosed by non-permeable halves of the pattern box, forming an outer cavity or flow space [70]. The pattern box [32] is mounted on two plates of the rotatable cage assembly, selectively positionable in at least three positions: charge, discharge, and transfer. Above the pattern box [32] are pivotally mounted material supply means [44], sealing means [96], and a trimmer [46]. Below the pattern box is a receiver [16] of an airless conveyor [14] for recirculation of the discharged unhardened material. The pattern box is connected to two manifolds: [61, 63] one [63] for consecutive supply of catalyst gas and the compressed air, another [61] for axhaust and venting. After material has been blown with the help of compressed air from the material supply means into the pattern inner cavity, it is sealed and the air is flushed out of the system by compressed catalyst gas introduced into the pattern box for about one second. Said gas then penetrates to desirable depth into material's outer layer starting polymerization and curing of its binder. After a few seconds, unsealed pattern box assembly is turned upside down and compressed air is blown into the pattern box, dislodging unhardened portion of the material out of the inside of the produced shell-like product. Consequently, the pattern box is opened and the product is transferred from the apparatus to a suitable place outside the machine.

Abstract: For an error correction method for the transfer of word-wise arranged data, two word correction codes are successively used, each code acting on a group of words while therebetween an interleaving step is performed. The actual transfer takes place by means of channel words for which purpose there are provided a modulator and a demodulator. Invalid channel words are provided with an invalidity bit in the demodulator. During the (possibly correcting) reproduction of the data words, the invalidity bits can be used in one of the two error corrections in various ways. When too many words of a group of code words are invalid, all words of the relevant group are invalidated. If a word comprising an invalidity bit is not corrected during correction by means of a syndrome variable, all words of the relevant group are invalidated. If the number of invalidity bits lies within given limits, they act as error locators so that the code is capable of correcting a larger number of words.

Abstract: A process for the production of pig iron from fine ore is described, in which initially the fine ore undergoes prereduction to a degree of metallization of preferably 65 to 75%. The sponge iron obtained is then melted down and under goes a final reduction. This process takes place in a melting cyclone 2, to which the sponge iron is supplied by means of a central opening 1 and into which are tangetially blown via a lateral opening 3 a carbon carrier, an oxygen-containing gas and optionally fluxes. As a result of the angular momentum produced, the sponge iron particles are deflected to the side and melted and finally reduced by the combustion gases of the carbon carrier. The molten iron collects in an iron bath 8. The gas produced in the melting cyclone is cooled from approximately 1500 DEG  C. to approximately 800 DEG  C. in a waste heat system 10, as well as by admixing cooling gas supplied via a line 11 and is then used for the prereduction of the iron ore.

Abstract: Control valve for a hydraulic elevator, provided with a speed regulating plug (2) moving with the flow of the hydraulic fluid, the position of the speed regulating plug determining the flow of hydraulic fluid into the actuating cylinder of the elevator, and a hydraulic channel system (1) forming an essentially closed loop. A problem with hydraulic elevators, in situations when the elevator is approaching a landing, is the difficulty of achieving a constant deceleration regardless of variations in the temperature of the hydraulic fluid. The invention solves this problem in that the hydraulic channel system (1) is provided with a flow resistance component (9) placed near either end of the speed regulating plug, the setting of said component being varied on the basis of the temperature of the hydraulic fluid. <IMAGE>

Abstract: In the process for separating ammonia from gases, in particular exhaust gases from combustion processes, in which ammonia is formed or released, or in which ammonia or a substance forming ammonia under the action of heat is fed, a material from the group of the zeolites is added to the gas to be purified as a treatment medium in fine distribution, with good mixing with the gas. The added compounds here have the advantage that they not only remove the ammonia very effectively from the exhaust gases by adsorption but can also bind it very firmly in their internal structure, whereby renewed release of ammonia in permanent storage is avoided.
