US Patent:

7365857, Apr 29, 2008

Filed:

Oct 21, 2005

Appl. No.:

11/255766

Inventors:

Michael Lowell Holmes - Lebanon CT, US
Andrew Eric Carlson - Higganum CT, US

Assignee:

Zygo Corporation - Middlefield CT

International Classification:

G01B 11/02

US Classification:

356487

Abstract:

Apparatus and methods for adjusting the polarizations of the components of an input beam to reduce leakage caused by imperfections in an interferometer are disclosed. The apparatus includes an interferometer positioned to receive an input beam that includes two components having different frequencies and different polarizations, the interferometer including a polarizing beam splitter positioned to spatially separate the input beam into two intermediate beams, the first intermediate beam corresponding to the first component and the second intermediate beam corresponding to the second component, where imperfections in the interferometer cause leakage of one of the components into the intermediate beam corresponding to the other of the components. The apparatus further includes a polarization compensator that includes at least one retardation plate positioned to adjust the polarizations of the components of the input beam to reduce the leakage caused by the imperfections in the interferometer.

Abstract:

High purity carbon sorbent monoliths that are particularly effective for the adsorption and subsequent desorption of trace-contaminants, such as ammonia, are produced by 3D-printing polymer monoliths, carbonizing them, and subsequently activating them to produce an effective amount of at least one type of oxygen species on exposed carbon surfaces. The high purity carbon sorbent monoliths are vacuum-regenerable on a time scale of a few minutes.

Abstract:

Apparatus is provided featuring a signal processor or signal processing module configured to receive signaling containing information about images of an ore sample; and determine information about a Bitumen Content of the ore sample based at least partly on the signaling, including for use in real time ore blend management in a bitumen recovery process related to mined oil sands. The ore sample may be an ore face, and the signaling may contain information about the images of the ore face. The signal processor or signal processing module may be configured to determine a real time ore face ore grade visualization based at least partly on the signaling, and provide corresponding signaling containing information about the real time ore face ore grade visualization, including a composite overlay image.
