摘要:
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).

A refrigeration device is provided that includes a housing enclosing an interior and an assembly in the interior having a storage compartment for chunks of ice and a stirrer. The stirrer is rotatable about an axis that extends through the storage compartment to move chunks of ice contained in the storage compartment in relation to each other and to move ice towards a dispensing passage that extends through the housing. A closable flap is interposed between the storage compartment and the dispensing passage.

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.

In one general aspect, a rheometer for measuring properties of a sample is disclosed. It can include a first part having a drive portion operatively connected to an actuator and having a contact surface for contacting the sample. The rheometer also includes a second part that has another contact surface for contacting the sample. A first heater is positioned to heat the first part, a second heater is positioned to heat the second part, and a heat pump can heat and cool both the first and second parts.
摘要:
The invention relates to a storing device for ice chunks that includes a receiving compartment for receiving therein ice chunks and a movable stirrer for effecting displacement of ice chunks received in the receiving compartment. The movable stirrer extends in the receiving compartment and rotates about a stirrer axis with the movable stirrer being disposed relative to the receiving compartment such that its stirrer axis extends through two surfaces of the receiving compartment. The movable stirrer is drivable in a stirring movement in a manner such that the movable stirrer effects displacement of the ice chunks with a substantial portion of the ice chunks not be advanced in a either a direction toward one of the two surfaces through which the stirrer axis extends of the other of the two surfaces through which the stirrer axis extends.
