Patent CH-673409-A5 (CH)
Inventor: CURTIUS FRIEDRICH RICHARD DIPL
IPC: B01D53/34
Filed: 1987-07-09
Abstract: In a process for the removal of nitrogen oxides (NOx) from pretreated flue gases having a nitrogen oxide content which is low by means of a multi-stage washing process employing a nitric acid (HNO3) solution to which is added hydrogen peroxide (H2O2), the process including a first stage in which the pretreated flue gases are received and contacted with nitric acid (HNO3) vapor to at least partially oxidize nitrogen monoxide (NO) present in the pretreated flue gases to nitrogen dioxide (NO2) and result in a first stage flue gas, and a second stage in which the first stage flue gas in received and washed with an aqueous nitric acid (HNO3) solution to which is added H2O2 to remove nitrogen dioxide (NO2) and any remaining nitrogen monoxide (NO) from the first stage flue gas and result in a second stage flue gas, wherein the pretreated flue gases have been treated to free the flue gases of contaminants including at least one of sulfur dioxide (SO2), hydrogen chloride (HCl) and hydrogen fluoride (HF), which contaminants are at least one of H2O2-decomposing or corrosive, and have been treated to free the flue gases of solid particles, the improvement including: adding to the first stage heat sufficient to prevent H2O condensation from the first stage flue gas; decontaminating the diluted nitric acid (HNO3) generated in the second stage when the nitrogen oxide content of the flue gas is above a defined level by, prior to the second stage, concentrating the nitrogen oxide in an absorption process; and providing a third stage in which the second stage flue gas is received and washed with a diluted, aqueous nitric acid (HNO3) solution to remove any remaining nitric acid (HNO3) vapor from the second stage flue gas.

Title: Device for handling strands or lamellae in a warp drawing.
Inventor: BADERTSCHER MARKUS
IPC: D03J1/14
Filed: 1990-09-17
Abstract: PCT No. PCT/CH91/00190 Sec. 371 Date May 11, 1992 Sec. 102(e) Date May 11, 1992 PCT Filed Sep. 3, 1991 PCT Pub. No. WO92/05303 PCT Pub. Date Apr. 2, 1992.The device serves to manipulate the healds or drop wires from their separation from a stack via the drawing-in of the warp threads up to the transfer to supporting members provided for arranging in a weaving machine and it contains holding devices for accepting the separated healds or drop wires and for positively transporting them to a drawing-in station and a transfer station, positioning elements arranged in the area of the drawing-in station, and transfer devices, arranged in the area of the transfer station, for transferring the healds or drop wires having a drawn-in warp thread to the supporting members. Consequently, only a single type of manipulating arrangement is required for manipulating the healds and drop wires from their separation up to the transfer to the supporting members. That results in a substantial reduction in potential sources of error and thus in the susceptibility to trouble. In addition, only two interfaces are necessary: one leading to the separating station and one at the transfer station leading to the supporting members.

Title: Process for producing foods storable for long periods, whose major constituent is dried common or sweet bananas
Inventor: KORN HELMUT
IPC: A23L19/00
Filed: 1984-12-11
Abstract: It is known to prepare from bananas flour for infant foods or a dry substance. The dry substance is tough and only edible with limitations and cannot be produced as a final end product having defined properties. In order to avoid these disadvantages and to obtain an end product, for example in the form of jam or the like having predeterminable properties, the following production process is provided. Dried bananas are distributed in water as a dispersion medium and converted into a mixture having a pasty behaviour. To the mixture are added in proportion other types of fruit masses - on occasion in combination with chocolate - and the mixture is mixed with an aqueous solution of sugar and then the consistency of the mixture is converted by drying from a liquid to a pasty phase. After each particular determination of the essential base data, in particular the carbohydrate and sugar contents, the processing of a defined mass as an intermediate product can be performed, which is then converted into the end product adjusted with respect to flavour.

Title: Extrusion die for multi core composite - filaments offers stable long-run operation
IPC: D01D5/36
Filed: 1970-07-10
Granted: 1971-05-07
Abstract: Die for forming composite filaments has several cores of one filament material dispensed in a matrix of a second material. The core streams discharge into a chamber which converges at an angle Theta of =75 degrees and which is fed with an annular and pref. also an axial stream of the matrix material. Pref. subsidiary passages sheath each core sub-filament in matrix material (co-axial or eccentric). For preparation of multi-core filaments or for manufacture of very fine filaments by subsequently removing the matrix material. Die design maintains stable core and matrix patterns throughout long prodn. runs - the flow path of the core filament streams is almost linear to avoid material hang-up and degradation. Sheathing of each core stream by matrix material avoids internal coalescence of the core streams.
