  • Patent number: 8109739
    Abstract: A dosing pump for a liquid additive in fuel of a heavy fuel engine includes a piston, a cylinder, and a high resolution linear actuator, including a motor driven by a controller, for moving the piston axially in the cylinder. The pump includes a manifold, and a low friction dish-shaped seal having a peripheral portion forming a seal between the cylinder and the manifold in a fully extended position of the piston. The dish-shaped seal includes a top portion attached to the piston that moves with the piston such that the top portion of the seal is compressed against the manifold in the fully extended position. The shape of the seal minimizes non-linearity of the volume dosed as a function of movement of the piston, and the controller drives the motor so as to remove a remaining non-linearity of the volume dosed as a function of movement of the piston.

  • Patent number: 8104297
    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.

  • Publication number: 20090277191
    Abstract: A tray (1) pivotably mounted in an automatic ice maker has a plurality of compartments (4) arranged in a number of rows and separated from one another by partition walls. The wall (6) extending above the upper edges of the partition walls (3) is formed at a longitudinal side of each row of compartments (4) and at at least a part of the transverse sides (2) thereof. For ice making, water (10) is filled into the tray (1) and allowed to freeze therein. Prior to letting the freezing take place, the tray (1) is pivoted from a tilted setting, in which the filled water (10) floods over the partition walls (3) between the compartments (4) of the tray (1) on a part of the width thereof and contacts a region of the longitudinal wall (6) extending above the upper edges of the partition walls (3), to an upright setting, in which the level of the water (10) lies below the upper edges of the partition walls (3).

  • Publication number: 20090173084
    Abstract: 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.
