Abstract: A device and system for optically analyzing food products is provided. The device comprises first and second imaging devices respectively sensitive to first and second wavelengths; the imaging devices include a line-scan camera to acquire images of food products at a line in a food-path-facing direction, and a line-scan spectrometer to acquire spectroscopic images at the line. The device includes an optical filter configured to: convey the first wavelengths from the line to the first imaging device; and convey the second wavelengths from the line to the second imaging device. The device includes a frame to align the optical filter and respective optical axes of the first and second imaging devices, relative to each other and the food-path-facing direction, such that the first imaging device and the second imaging device are optically aligned via the optical filter to image the line.

Abstract: A lamp for illuminating food products along a line is provided. The lamp comprises: a housing having a longitudinal axis and an opening along the longitudinal axis; a light source located in the housing along the longitudinal axis; a reflector positioned in the housing along the longitudinal axis, the reflector to reflect light from the light source through the opening and focus the light along the line; a removeable frame attached to the housing around the opening, the removeable frame having an aperture aligned with the opening along the longitudinal axis; a glass window in the aperture; a transparent polymer film in the aperture at an outward facing side of the glass window, each of the glass window and the transparent polymer film extending into the removeable frame past a perimeter of the aperture; and a seal between the transparent polymer film and the perimeter of the aperture.

Abstract: Novel derivatives of dihydro-1,4,2-oxathiazine and dihydro-1,4-dithiine oxides, more particularly, novel derivatives of dihydro-1,4,2-oxathiazine and dihydro-1,4-dithiine oxides that target cysteine residues of biomolecules of pharmacological importance are provided as pharmaceutically useful compounds, for example, as anticancer, antiinfectious, antigastric acid secretion, antiosteoporosic, and antiinflammatory agents.

Abstract: A method is disclosed for the preparation of benzo[b]thiophenecarbodithioic esters of the formula: wherein R is alkyl, R1 is hydrogen, halogen, or alkyl, R2, R3, R4, and R5 are independently selected from the group consisting of hydrogen, halogen, alkyl, alkoxy, alkylthio, trifluoromethyl, cyano, and aryl, wherein said method comprises reacting an equivalent of an S-thiol ester of the formula: with one-third of an equivalent of P2S5, 2 equivalents of at least one alkali metal carbonate, about 2.5 mole percent of a phase transfer catalyst, and a catalytic amount of water in hot toluene.
