Abstract: A method and apparatus for purifying carboxylic acids is disclosed. A mixture containing crude carboxylic acid is contacted with a selective crystallization solvent to form a slurry of a salt complex of the carboxylic acid and the selective crystallization solvent. The salt complex is recovered and optionally processed to recover the free carboxylic acid. The method and apparatus of the invention is particularly suitable for purifying aromatic dicarboxylic acids such as terephthalic acid. The present invention also reduces contamination by carboxybenaldehyde isomers in crude phthalic acids by oxidizing the carboxybenzaldehyde to the corresponding phthalic acid.

Abstract: A system and method of measuring a rotational motion of a code wheel measures a rotational movement of the code wheel including an error component due to a non-rotational movement of the code wheel; measures the non-rotational movement of the code wheel; and produces an error-corrected measurement of the rotational movement of the code wheel by using the measured non-rotational movement of the code wheel to cancel the error component of the measured rotational movement of the code wheel. A signal can be produced indicating a need for maintenance when the non-rotational movement of the code wheel exceeds a threshold.

Abstract: A projection apparatus includes a main body and at least one movement auxiliary device disposed adjacent to the main body to help for moving the projection apparatus. By using the movement auxiliary device, a user can change the position and the projection direction of the projection apparatus easily.

Abstract: A backlight button assemblage includes an opaque button, a light-guiding element, and a light-emitting element. The light-emitting element is disposed under the button and light emitted from the light-emitting element is guided to the front side of the button via the light-guiding element surrounding the button. Light can therefore be evenly distributed over the light-guiding element, and uniformity of light achieved, so that partial dazzling spots are avoided, the quantity of light-emitting elements is reduced, and fabrication costs are saved.
