摘要： This invention relates to a method of producing purified methyl isobutyl ketone (MIBK) comprising subjecting a feed stream containing MIBK and impurities to a first distillation procedure from which acetone is recovered and a bottom product containing MIBK and impurities is withdrawn. This bottom product is fed to a second distillation column, where a vapour overhead product is withdrawn, condensed and fed to an overhead liquid-liquid separator. Part of an organic phase from the overhead liquid-liquid separator is fed to the second distillation column and part is fed to a third distillation column. A vapour overhead product is withdrawn from the third column which is condensed in the same said condensor. The condensed product is fed to the same said overhead liquid-liquid separator, and purified MIBK is withdrawn from the third distillation column. This invention also relates to an apparatus used in such a method.

摘要： The invention relates to a method for extracting xenon and eventually also krypton from a liquid oxygen (LOX) charge, as it accrues in a cryogenic air separation system (LZA) during a rectification of the air, mostly as a bottom product of a low-pressure, column, namely with xenon (Xe), krypton (Kr) and hydrocarbons (CxHy) in a small concentration and approximately 99 mol % oxygen (O2). According to the inventive method, the LOX charge is fed to a first column, the oxygen of the LOX charge is extensively removed by stripping with an inert gas, and is extracted in the top gas, whereas the inert gas is withdrawn in the form of a liquid from the bottom of the first column with little O2 and nearly the total mass of CxHy, Kr, Xe. According to the invention, the liquid discharge is fed to a second column without prior catalytic and/or adsorptive removal of CxHy. A Kr fraction is extracted as top gas of the second column, and an Xe fraction is withdrawn from the bottom of the second column. The method can be used in a device for extracting Xe and/or Kr in an air separation system (LZA). The device can be arranged in a transportable container.

The bottom product of the first distillation procedure is fed to a liquid-liquid separator and an organic phase from the said liquid-liquid separator is fed to the top region of a second distillation column to produce an overhead product. The said overhead product is condensed and fed to the said liquid-liquid separator. A bottom product containing MIBK is withdrawn from the second distillation column. This bottom product is fed to a third distillation column, high boiling impurities are withdrawn as a bottom product, and purified MIBK is also withdrawn. The invention also relates to an apparatus used in such a method.

摘要： A document photographing device has a surface for supporting a document to be photographed, a camera positioned about the surface, to receive light reflected from and transmitted by a document supported on the surface, and separate means for illuminating the document from above and below respectively. An exposure meter receives light reflected from or transmitted through the document and indicates when correct exposure conditions have been set. The exposure meter includes correction means for correcting the reading of the exposure meter to take account of the different spectral radiation characteristics of the illuminating means.

摘要： A cover is provided to protect the sight of an archery bow from distortion caused by falling precipitation, regardless of the horizontal position of the bow. The bow is provided with a sight having a lens; the sight is attached to the bow by a bracket. A cover is pivotally attached to the bracket, and includes an upper protective hood over the sight, and a lower counterweight. The counterweight is of sufficient weight so that the cover will pivot about the bracket as the bow is pivoted about a horizontal axis, or laid down, so the hood will maintain its protective position above the sight.
