Abstract: A yarn take-up and supply mechanism for use with textile machines processing yarn, such as during a threading-up operation of the machine, characterized by a construction for coiling a given length of yarn into a single-layer winding to produce a yarn storage and for releasing the stored yarn to the textile machine in a substantially tension-free condition, including the following. A selectively-rotatable elongate drum is operatively mounted at one end on a frame portion of the mechanism and defines an outwardly-extending overhanging free other end for winding of a given length of the yarn on the outside surface thereof. Selectively-operable clamping devices are mounted on and positioned generally at the free end of the drum for receiving a free end of the yarn and for clamping the free end of the yarn during winding of the yarn on the drum and for releasing the free end of the yarn after winding for supplying of the yarn to the textile machine from the surface of the drum by unwinding.

Title: Extracellular microbial lipoheteropolysaccharides and derivatives, their preparation and compositions containing them, and their uses.
IPC: C09K23/00
Filed: 1980-02-21
Abstract: Growth of Acinetobacter Sp. ATCC 31012 on various substrates and under varying conditions has been used to produce two classes of extracellular microbial protein-associated lipopolysaccharides (the "emulsans") which, on a weight-for-weight basis, are probably the most efficient emulsifiers discovered and which possess certain characteristics that permit these unique extracellular microbial lipopolysaccharides to be widely used in cleaning oil-contaminated vessels, oil spill management, and enhanced oil recovery by chemical flooding. These classes have been named alpha -emulsans and beta -emulsans, both of which have substantially the same polymer backbone but differ from each other in certain important structural aspects. Deproteinization of emulsans by hot phenol extraction produces the lipopolysaccharide components (the "apoemulsans") of each of such th emulsans, which components have been shown to be completely N-acylated and partially O-acylated heteropolysaccharides made up of a major amounts of D-galactosamine and an aminouronic acid, the O-lipoacyl portions of such apoemulsans containing varying percentages of fatty acid esters in which the fatty acids contain from about 10 to about 18 carbon atoms. Base hydrolysis under mild conditions of the emulsans and apoemulsans produces derivatives (the " psi -emulsans" and apo- psi -emulsans", respectively) which are completely N-acylated and partially to completely O-deacylated. Base hydrolysis under strong conditions of any of these products produces another derivate (the "proemulsans") which is completely O-deacylated and is partially H-deacylated. Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components. In addition, these extracellular microbial polysaccharides as well as their O-deacylated and N-deacylated derivatives are adsorbed on and capable of flocculating aluminosilicate ion-exchangers, such as kaolin and bentonite.

Patent ES-8200725-A1 (ES)
Title: Process for the decarburisation of chromium containing melts.
IPC: C21C5/00
Filed: 1981-01-23
Abstract: A process is disclosed for the decarburization of a molten bath of chromium-containing pig iron which, in a single operation, permits decarburization by means of an oxygen jet and thus permits chromium or nickel chromium steels to be obtained directly, the decarburization of which can readily be completed by a final treatment under vacuum carried out immediately after the injection of oxygen. The process comprises adjusting the temperature conditions of the pig iron bath and regulating the oxygen jet distance from the surface of the bath and speed of oxygen gas so that the impact force of the oxygen creates a gas-metal emulsion within which the carbon contained in the pig iron is oxidized directly by the oxygen. The carbon content is thus rapidly reduced to less than 0.3% whereas the yield of chromium is higher than 97%. The process is suitable for the preparation of all grades of Cr and NiCr stainless steel, which optionally contain additions of Co, Mn or Mo.
