  • Publication number: 20090025401
    Abstract: An ice-maker tray (1) has several compartments (4), which each have the form of a segment of a body of rotation. When the content of the compartments (4) is frozen, the tray (1) suspended in a frame (15) of an ice maker is pivoted about an axis, which is parallel to the axes of the segments of the body of rotation, until the openings of the compartments (4) face downwardly and the pieces of ice thawed by heating can slide out of the compartments.

  • Patent number: 6122055
    Abstract: An evaporative light scattering detector (1) has a solvent nebulizer (4) through which an atomised spray of solute solvent solution passes, a heated evaporation chamber (5) and a detector system (6). A diffuser trapping device (7), supported by fine wires, is positioned in the evaporation chamber(5) at about two fifths of the height of the chamber from the top. The diffuser trapping device (7) is made from randomly coiled stainless steel ribbon which gives it a large surface area. The detection system (6) is positioned at the bottom of the evaporation chamber through which a beam of collimated light passes and is scattered by the solvent and detected by a light sensitive device (14). The diffuser trapping device (7) aids evaporation of the solvent and prevents large particles from travelling further down the evaporation chamber (5).
