Patent ES-444131-A1 (ES)
Title: Piston ring forming method
IPC: F16J9/12
Filed: 1976-01-08
Abstract: A method and apparatus for forming piston rings are disclosed. A split piston ring made by conventional processes is locally heated along its inside surface for a short distance either side of the split. This causes a short length of the ring on either side of the split to curl into a slight inward protrosion due to internal yielding of the restrained heated area and subsequent tensioning during cooling. The inwardly curved configuration prevents catching of the ring's ends on gas ports of ported cylinder engines.

Patent ES-467555-A1 (ES)
Title: Process for pressure stripping of sulfur dioxide from buffered solutions
IPC: C01B17/60
Filed: 1978-03-03
Abstract: A process for steam stripping sulfur dioxide from a buffered aqueous solution in which it is absorbed in a flue gas desulfurization process is carried out at pressure greater than atmospheric. The process of pressure stripping of sulfur dioxide surprisingly results in increased steam economy as compared to stripping at atmospheric pressure and yields sulfur dioxide vapor which can be directly condensed to a liquid product with ordinary cooling water, eliminating the need for drying, refrigeration or compression operations. The high temperatures corresponding to high steam pressures enable economical use of stripping vessel overheads for preheating operations also. Stripping at pressures of 50 to 65 psig results in steam requirements which are only one-third to one-half of that at atmospheric pressure stripping. At the high pressures lower gas flow rates permit the use of more compact stripping equipment.

Title: Impact wrench
IPC: B25B21/02
Filed: 1980-04-02
Abstract: A self-contained impact wrench having an adaptive control system for determining the yield point or some similarly significant tightened condition of a fastener assembly by detecting a signal representative of the forward rotation angle of the fastener assembly is disclosed. One embodiment utilizes a computed signal of time over a fixed interval of forward rotation angle, as an estimate of the torque applied by the impact wrench, and the torque estimate vs. rotation angle curve is differentiated to obtain the gradient thereof. Successive gradient values are stored and compared, and when the present gradient value has attained a predetermined relationship relative to a stored value of a gradient in a tightening region of the curve, further tightening of the fastener assembly is discontinued. This ensures that the yield point or other similarly significant tightened condition of the assembly has been reached.
Patent ES-8202264-A1 (ES)
Title: Extracellular microbial lipoheteropolysaccharides and derivatives, their preparation and compositions containing them, and their uses.
IPC: C09K23/00
Filed: 1981-03-02
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.
