Abstract: Disclosed are systems, devices, and methods for detecting characteristics of an unhatched egg. A set of images of an unhatched egg are obtained, where each of the spectral images is obtained in a particular wavelength range. The set of images is processed to extract image features, where the image features includes an image texture feature. The extracted image features are processed to classify the unhatched egg according to at least one characteristic. The at least one characteristic may include fertility and/or gender.

Abstract: An egg flat identification system for identifying an egg flat among a collection of egg flats is provided. Such a system includes a first measurement device configured to determine a first measurement of a plurality of eggs carried by an egg flat. A processor is in communication with the first measurement device. The processor is configured to receive the first measurements from the first measurement device. A second measurement device is configured to determine a second measurement of the eggs in the collection of egg flats. The second measurement device is in communication with the processor such that the processor is capable of receiving the second measurements. The processor compares the second measurements with the first measurements so as to identify a respective egg flat among the collection of egg flats.

Abstract: The present invention relates to a coating composition comprising a bis-type silane compound, and particularly relates to a coating composition which has high storage stability and can form a highly transparent and high-strength coating film, a preparation method thereof and a coating film formed using the same.

Abstract: Embodiments of the current invention describe a high performance combinatorial method and apparatus for the combinatorial development of coatings by a dip-coating process. The dip-coating process may be used for multiple applications, including forming coatings from varied sol-gel formulations, coating substrates uniformly with particles to combinatorially test particle removal formulations, and the dipping of substrates into texturing formulations to combinatorially develop the texturing formulations.

Abstract: An apparatus for classifying a plurality of poultry eggs includes means for detecting the opacities of the eggs, means for detecting the temperatures of the eggs, and means for classifying the eggs using the opacities and the temperatures of the eggs. A method for classifying poultry eggs includes measuring the opacities of the eggs, measuring the temperatures of the eggs, and classifying the eggs as a function of the opacities and the temperatures of the eggs.

Abstract: Improved process for fluidifying flocculated aqueous suspensions of red muds in the production of alumina from bauxite by the Bayer process, which consists:in dissolving bauxite using sodium hydroxide;then, in decanting and in washing the red muds formed in order to separate them from the alumina in successive vats, while recycling the washing waters upstream;and finally, in eliminating the red muds thus treated;and in which a flocculant (F) consisting of a polyacrylamide of molecular weight greater than ten million is introduced into the suspension of one of the successive vats;wherein a dispersing agent (D) formed by an anionic acrylic acid polymer of molecular weight lower than fifty thousand is added simultaneously with said flocculant (F) to the suspension in the same vat.

Abstract: Method for extracting metals amalgamatable with mercury from fluid material containing those metals in the form of metal particles. The method comprises contacting a slurry or aqueous solution containing metal particles of the metal to be recovered by amalgamation with a surface of a support amalgamated with mercury to form on the surface an amalgam with the metal to be recovered. A surface film is continuously removed from the surface of the support, and the surface of the support is continuously restored by electrolytic deposition of mercury thereon.
