Abstract: An assembly for rotating a workpiece including a locking side pull hoist ring removably attachable to a side surface of the workpiece. The locking side pull hoist ring comprises a load bearing structure, a rotation mechanism attached to the side surface of the workpiece that rotates about a rotation axis extending through the rotation mechanism, a locking mechanism configured to transition between a locked state and an unlocked state, and a support member connecting the load bearing structure and the rotation mechanism. The support member rotatably supports the rotation mechanism for rotation about the rotation axis and rotatably supports the load bearing structure for rotation about a second axis. In the locked state, the locking mechanism prevents rotation of the rotation mechanism by securing the rotation mechanism to the support member.

Abstract: Disclosed is a process for removing acids in a system in which aromatic hydrocarbons are separated from a mixture with aliphatic hydrocarbons. The aromatic hydrocarbons are extracted from the mixture using an extracting solvent. The aromatic hydrocarbons are stripped from the extracting solvent with steam and the steam is condensed to form water which is separated from the aromatic hydrocarbons. The separated water is passed through a basic anion exchange column and is then heated to produce the steam.

Abstract: A method and structural component for use in constructing geodesic domes using standardized polygon panels. The invention allows for the use of a reduced number of components to construct a geodesic dome. In one embodiment, a set of kite-shaped quadrilateral panels with an external convex surface are used to substantially construct a geodesic dome. A panel includes two lip seal panel edges. The lip seam edge includes an inwardly disposed lip forming a mating surface suitable for mating with an adjacent straight seam edge of a corresponding panel so that the engagement between the two edges forms a seal. The seal may be made to impede moisture by various fastening methods, including screwing, riveting, gluing, taping or welding. Practice of the invention reduces transportation, inventory, and handling expense. Procurement, assembly, and maintenance complexity for the end user is also reduced.

Abstract: A system and method is described for automatically editing digital images. An image to be edited is selected and registered with a model that is an abstract of features and attributes common to a category of images to which the selected image belongs. In the illustrated embodiment, a human face is used as an example of an image to be edited and the matching model is a representation of features and attributes common to all human faces. Many other images of objects may also be edited using the techniques of the invention, as long as a general class of objects to which an image belongs is amenable to being represented by a model comprising a set of common features or attributes. A library of different models is available to the user for selecting the model matching the image to be edited. The library includes different models of the same object in different orientations and may also include models of different objects.
