摘要:
The invention provides novel ceramic mass transfer packing elements with physical characteristics that maximize efficiency of mass transfer and minimize pressure drop when randomly dumped in a chemical reactor. In some embodiments, the elements may have: a ratio of surface area of the interaction zone to surface area of the flow through zone between 1:0.5 and 1:3; and the interaction zone surface area occupies between 45% and 70% of the open face surface area.

摘要:
A chemical processing apparatus that utilizes randomly oriented ceramic packing elements having at least three openings therethrough that accommodate feedstock with combustible and/or noncombustible matter that accumulates in the openings is described. The openings occupy at least 10% of the surface area on one side of the packing element.

This invention provides a packing element for use in a chemical processing apparatus housing a mass transfer reaction. The packing element has lobes and channels radially disposed around a common axis and alternately spaced from one another. The lobes abut at least 60% of the circumference of the smallest circle that circumscribes the element and the channels form openings that abut no more than 40% of the circumference.

Methods and systems for processing coverings such as leather hides and fabrics are provided. A system can include a worktable having a surface on which a covering is placeable. An imaging device can be positionable relative to the worktable. The imaging device can be configured to obtain an image of the covering on the surface of the worktable. A projector can be positionable relative to worktable. The projector can be configured to project an image onto the surface of the worktable and the covering on the surface of the worktable. A controller can be in communication with the imaging device and projector. The controller can be configured to correct images taken by the imaging device. The controller can also be configured to correct the images projected onto the surface of the worktable and the covering thereon. The controller can be configured to permit the showing of virtual markings on the covering placed on the surface of the worktable through an image projected thereon by the projector. The covering can then be marked or cut along the virtual markings.
摘要:
A tower (A) for effecting heat transfer or chemical reactions contains a packing (B) formed from a multitude of packing elements (2, 28). Each element includes a peripheral wall (10, 30) and a convoluted interior wall (12, 32) that spirals inwardly from the peripheral wall toward the center of the element, thus forming a convoluted passage (14, 34) through the element. The convoluted passages in the elements capture the flow of fluid through the packing so that less fluid follows voids between the elements and more flows through the elements. Moreover, the convoluted interior wall of each element provides a large surface area for heat transfer or chemical reactions.

Basically, this invention provides for an inbred corn line designated G07-NPXA5489, methods for producing a corn plant by crossing plants of the inbred line G07-NPXA5489 with plants of another corn plants. The invention relates to the various parts of inbred including culturable cells. This invention also relates to methods for introducing transgenic transgenes into inbred corn line G07-NPXA5489 and plants produced by said methods.
