Title: Fermentation additive to animal fodder, method for its preparation and use
Inventor: BINDER WOLFRAM
IPC: A23K1/00
Filed: 1994-03-15
Abstract: 2. Animal feed additives based on fermentation broth further contain, in addition to the additive, other fermentation broth constituents. Such products, after spray-drying, generally have an excessively low bulk density and/or are sticky. To granulate these products, processing aids have therefore been added, e.g. perlite or sawdust. Alternatively, such products have been dewatered by azeotropic distillation with paraffin oil to give granules. The object of the invention is a highly concentrated animal feed additive which, in particular, is to have a bulk density of at least 550 kg/m<3> and a standardisable active compound content. 2.2. By pelletising, stable granules can be produced from an animal feed additive-containing fermentation broth if the fermentation product is contained at at least 33% by weight. Granules can particularly readily be produced by pelletising if the pellets are built up of at least 30% by weight fine grain with at least 70% by weight having a particle size < 100  mu m. The biomass can be contained completely, in part or not at all in the granules. 2.3. Animal feed additives such as lysine, threonine or tryptophan, or containing fermentation broth products.

Abstract: Текстилният материал има подобрени топлоизолационни, термофизиологични и хигиенни показатели и с него се оптимизира технологията за конфекциониране на облеклото. Съставен е от влакнеста ватка, представляваща синтетични щапелни влакна и/или техни смеси с естествени влакна, като влакната са разположени напречно, и полиетиленово фолио, като са свързани помежду си чрез иглонабиване. Методът включва смесване на влакната, развлачване и формиране на дарашка ватка, след което те участват в слоеве, които се настилат един върху друг и се подлагат на едновременно двустранно иглонабиване до достигане на специфична площна маса от 80 до 130 g/м2. Така получената ватка се настила върху полиетиленовото фолио и влакната се подлагат на едностранно иглонабиване откъм страната на влакнестата ватка, а полученият нетъкан текстилен материал се навива на руло.

Abstract: A universal inkjet cartridge body with multiple ink reservoirs that can be used for single color or multiple color applications. The ink flow routing is accomplished by merely changing the printhead-to-body sealing structure, which can be an adhesive pattern. This allows for all the reservoirs' inks to be mixed at the head for one cartridge configuration, or the respective inks can be directed to different parts of the printhead for a multiple color application. The same cartridge body structure can be used for two or more cartridge configurations. A nose piece structure defines multiple ink channels leading from the respective ink reservoirs to a printhead mounting region. The sealing structure is applied to mount the printhead to the nose piece and to complete the ink path routing from the reservoirs to the printhead nozzle array(s).
