Title: Method for purifying aromatic amines
Inventor: GEHLEN FRANZ-ULRICH
IPC: C07C209/84
Filed: 2008-08-05
Abstract: Purifying aromatic amines, produced by reduction of aromatic nitro compound, comprises separating reaction water generated during the reduction; mixing the raw amine (1) with an aqueous solution of an alkali hydroxide (2); feeding the mixture into a distillation column; partially/completely extracting the residue; partially vaporizing the residue in a main vaporizer and at least one post vaporizer; and completely returning the gas phases (10), and partially refeeding the fluid phases in the column and partially/completely discharging the liquid phase that occurs in the post evaporator. Purification of aromatic amines, which are produced by reduction of aromatic nitro compound, where the product mixture obtained from the reduction step is subjected to the cleaning process, comprises separating the reaction water generated during the reduction step by phase separation, where the obtained raw amine has a solubility of water in raw amine conforming to the remaining quantity of raw amine to water, which is dependent on pressure and temperature as well as the exact composition of the raw amine and which has 4-10 mass.% of the raw amine; mixing the obtained raw amine with an aqueous solution of an alkali hydroxide; feeding the mixture into a distillation column, where the distillation column has an upper reinforcing part, a lower reinforcing part and an output part; partially or completely extracting the residue from the area below the output part; optionally vaporizing the residue; partially vaporizing the obtained residue in a main vaporizer and at least one post vaporizer kept downstream, where the post vaporizer at high temperature is operated than the main evaporator up to a residual content of aromatic amines in the operation of the post vaporizer of 0-98 mass%; and completely returning the obtained gas phases, and partially refeeding the fluid phases in the column either below or over the output part and partially or completely discharging the liquid phase (5) that occurs in the post evaporator.

Title: Data processing apparatus and method
Inventor: TAYLOR MATTHEW PAUL ATHOL
IPC: H03M13/27
Filed: 2008-10-15
Abstract: A data processing apparatus is arranged to map input data symbols to be communicated onto a predetermined number of sub-carrier signals of Orthogonal Frequency Division Multiplexed OFDM symbols. The predetermined number of sub-carrier signals is determined in accordance with one of a plurality of operating modes and the input data symbols are divided into first sets of input data symbols and second sets of input data symbols. The data processing apparatus comprises an interleaver operable to perform an odd interleaving process which interleaves the first sets of input data symbols on to the sub-carrier signals of first OFDM symbols and an even interleaving process which interleaves the second sets of input data symbols on to the sub-carrier signals of second OFDM symbols, such that while the input data symbols from the first set are being read from locations in the interleaver memory, input data symbols from the second set can be written to the locations just read from and when input data symbols from the second set are being read from the locations in the interleaver memory, the input data symbols from a following first set can be written to the locations just read from. Furthermore, when the number data symbols which can be carried by the sub-carriers of an OFDM symbol in one of the plurality of operating modes is half or less than half of the number of data symbols, which can be carried in an operating mode which provides the most number of data bearing sub-carrier signals per OFDM symbol, the data processing apparatus is operable to interleave the input data symbols from both first and second sets in accordance with the odd interleaving process on to the first and second OFDM symbols, and to change the permutation code which is used to form the addresses from one OFDM symbol to another.

Title: Purifying a fluid medium
IPC: A61L2/10
Filed: 1980-01-16
Abstract: Various embodiments of photoreactors are disclosed which have at least two irradiation chambers with a window therebetween. Ultraviolet radiation is introduced into one of the chambers at a side opposite the window so that it passes through that chamber, through the window and into the other chamber. The fluid medium to be purified is passed through the chambers and subjected to the radiation while in the chambers. The flow of the medium is through the chambers in series. The chambers are optimized in depth with respect to efficiency in terms of the flow-dose rate. In a two chamber photoreactor traversed by parallel radiation the maximum is at a total absorption of about 70 percent and at an absorption of about 27 percent in the chamber immediately adjacent to the radiation source. In an annular two chamber photoreactor with an elongate radiation source extending along the axis thereof the corresponding data are 45 to 65 percent and 16 to 25 percent, respectively. In an immersion type three chamber photoreactor of analogous configuration the corresponding data are 60 to 80 percent and 14 to 20 percent, respectively.

Title: Dedicated ribosomes
IPC: C12P21/00
Filed: 1986-03-26
Abstract: A method is described that dedicates specialized ribosomes to the synthesis of desired proteins. DNA which encodes rRNA having a mutant anti-Shine-Dalgarno sequence is used to transform a host cell in combination with DNA encoding messenger RNA for the desired protein having a complementary mutant Shine-Dalgarno sequence. Since the mutant sequences are selected so as to be substantially unrecognized by either endogenous messenger RNA or ribosomes, respectively, the synthesis of protein proceeds in a dedicated system without interference from other host cell protein synthetic machinery.

Abstract: In a fire alarm system individual fire alarms are connected in series by reporting lines with a central signal station. In order to be able to connect a greater number of fire alarms with the individual reporting or signaling lines and/or in order to be able to dispatch an increased amount of current through the reporting lines, the reporting or signaling lines from the last fire alarm of a line are returned back to the central signal station in the form of a ring circuit or loop. Upon the absence of signals at a reporting line an interrogation device is reversed, so that there can be ensured that in the event of a line disturbance or breakdown of a fire alarm the remainder of the fire alarms still can be utilized for giving a signal. The individual fire alarms are structured such that during assembly the inputs and outputs can be mutually interchanged.

Abstract: A vacuum cleaner housing possesses two guide means on the inner side of the end housing wall with a suction port therein in order to receive the board flange of a dust bag adjacent to the lateral housing wall. The guide means comprise guide rails each with a ramp-like wall, extending towards said housing wall, and guide ribs which are located in the lower part of the housing wall and have a slope opposite to that of the ramp-like walls. They are so shaped as to allow the board flange to be inserted between them and the walls. On introduction of such a board flange of a dust bag its lower end section is bent along a prepared line of bending, which has been formed in the lower part of the board flange parallel to its lower side. Accordingly the board flange is so firmly held in place that it is not bent by the suction force to which it is exposed. The vacuum cleaner housing is further made with a cover stop which prevents closure of the cover unless a dust bag has been previously placed in the vacuum cleaner housing.

Title: Method for purification and exploitation, by microbiological¹means, of an organic effluent comprising a fermentable sugar
IPC: C12N1/16
Filed: 1989-04-19
Abstract: The invention relates to a process for purification and valorisation of effluents, especially from the agri-foodstuffs or agricultural industries, using a coculture of selected yeasts, which process consists in employing under aerobic conditions two strains capable of establishing themselves in a dominant manner in a medium comprising at least the effluent in question constituting the substrate, namely a first yeast strain belonging, for example, to the species Candida kefyr, preferentially metabolising the fermentable sugar, and a second strain belonging, for example, to the species Candida valida, preferentially metabolising the by-products of residual fermentation of the first strain. This process finds its main application in the agri-foodstuffs industry, in particular in the treatment of crude whey, dairy permeates, or alternatively effluents from confectionery or vinegar manufacture or from sugar refineries.
