    Abstract: A shoelace centering device for securely holding a shoelace centered between bottom eyelets of a shoe and maintaining opposite tie ends of the shoelace even in length is provided. The shoelace centering device comprises a first securing portion and a second securing portion. A hinge connection is provided between the first and second securing portions with the hinge connection allowing the first and second securing portions to move from a non-contacting open position to a contacting closed position. A locking mechanism releasably secures the first and second securing portions in the contacting closed position. Upon positioning the bottom eyelet shoelaces between the first and second securing portions when the first and second securing portions are in the non-contacting open position. Upon releasably securing the first and second securing portions together in the contacting closed position, the shoelaces are anchored from shifting and maintaining opposite tie ends of the shoelace even in length.

    Abstract: An adjustable spine distraction implant alleviates pain associated with spinal stenosis and facet arthropathy by expanding the volume and/or cross sectional area in the spinal canal and/or neural foramen. The adjustable implant provides a spinal extension inhibitor. The implant includes elliptical or oval shaped adjustable member or spacer for positioning between and adjustably spacing apart the spinous processes.

    Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using an extractive distillation column. A diluted acid stream, comprising less than 30 wt. % acetic acid, is used as the extractive agent and is fed at a point above the crude feed stream. The column yields a residue that comprises ethanol, acetic acid, and water. The diluted acid stream may be separated from the residue and returned to the extractive distillation column.

    Abstract: Recovery of ethanol from a crude ethanol product obtained from the hydrogenation of acetic acid using an extractive distillation column. The column yields a first residue that comprises ethanol, ethyl acetate, acetic acid, and water. The first residue is separated in a second column to yield a second distillate comprising ethanol and ethyl acetate. The second distillate is then separated in a third column to yield a third distillate comprising ethyl acetate and a third residue comprising ethanol.

    Abstract: Two or more vapor-liquid separators are used in a process for removing at least one non-condensable gas from a crude alcohol mixture prepared by hydrogenating alkanoic acid and/or esters thereof. The vapor-liquid separators may comprise flashers or knock-out pots and are suitable for removing non-condensable gas, including those gases that are dissolved in the liquid. The multiple vapor-liquid separators may be in series prior to any separation of organic components. In addition, there may be a vapor-liquid separator before and after a distillation column for treating the feed to the column.
