  • Optimized production of aromatic dicarboxylic acids
    Patent number: 7959879
    Abstract: Disclosed is an optimized process and apparatus for more efficiently producing aromatic dicarboxylic acids (e.g., terephthalic acid). In one embodiment the process/apparatus reduces costs by recovering and purifying residual terephthalic acid present in the liquid phase of an initial oxidation slurry. In another embodiment the process apparatus reduces costs associated with hydrogenation by forming a final composite product containing unhydrogenated acid particles.

  • Optimized liquid-phase oxidation
    Patent number: 7960581
    Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

  • Punch pliers having lower costs of fabrication
    Patent number: 7895756
    Abstract: A pair of punch pliers include a handle, a control shank assembly, a punching member, and a connecting device. The handle has a first end provided with a grip portion, a second end provided with a punching seat and a mediate portion provided with a hollow receiving base. The control shank assembly includes two press members each pivotally mounted on the receiving base of the handle, and a press block mounted between the two press members. Thus, the blanks of the handle are juxtaposed to each other, and the blanks of each of the two press members of the control shank assembly are juxtaposed to each other, so that the wasted materials of the handle and each of the two press members are reduced largely, thereby decreasing the costs of fabrication of the punch pliers.

  • METHOD AND SYSTEM FOR MARKING SCENES AND IMAGES OF SCENES WITH OPTICAL TAGS
    Publication number: 20100079481
    Abstract: A method and system marks a scene and images acquired of the scene with tags. A set of tags is projected into a scene while modulating an intensity of each tag according to a unique temporally varying code. Each tag is projected as an infrared signal at a known location in the scene. Sequences of infrared and color images are acquired of the scene while performing the projecting and the modulating. A subset of the tags is detected in the sequence of infrared images. Then, the sequence of color image is displayed while marking a location of each detected tag in the displayed sequence of color images, in which the marked location of the detected tag corresponds to the known location of the tag in the scene.
