  • Patent number: 9016930
    Abstract: An apparatus for swirling wine within a wine glass or a decanter, or for moving a liquid within a container. A driver is mounted to move a driving element with respect to a housing. A base for holding or removably attaching the glass, the decanter or the container, is moveably mounted with respect to the housing. A receiver and a connector are moveably mounted with respect to each other and with respect to the housing. When the driver moves the base, the base and thus the container follow a path defined by movement of the connector with respect to the receiver. When the glass, the decanter or the other container is mounted with respect to the base, the base moves the glass, the decanter or the container to impart a swirling motion of wine or another liquid within the glass, the decanter or the container.

  • Patent number: 6850020
    Abstract: Apparatus and method for automatically determining which of at least two forces to apply to a paint container in a mixing apparatus that is capable of clamping various sized paint containers. A clamp motor drives a clamping apparatus toward a paint container and a current rise signals engagement of the clamp with the container, whereupon a selection is made from a predetermined set of forces to apply to the container based on the time of energization and voltage applied to the clamp motor.

  • Patent number: 6830935
    Abstract: a method for separating particulate matter from a fluid, using apparatus which includes a container and cover, a filter assembly positioned in a housing atop the cover and suitable for collecting particulate matter in the fluid on a collection surface, and a dispersing element fixed relative to the cover. The cover has a portion that is fixed in a first position and freely rotatable in a second position. The specimen is placed in the container, and a mixer apparatus rotates the container in relation to the cover to disperse the particulate matter throughout the fluid. Upon deactivation of the mixer apparatus, a fluid sample including dispersed particulate matter is drawn through the filter assembly to capture a substantially uniform layer of particulate matter on the collection surface. The housing is then opened to expose the layer of particulate matter, which is then transferred to a microscope slide.

  • Publication number: 20040240314
    Abstract: An insert for a container includes an outer wall, a upstanding spout, and a bottom wall. The outer wall is configured to fit within an opening of the container and defines the periphery of the insert. The outer wall has a lower edge and an upper edge that is disposed at a first elevation. The upstanding spout is located within the outer wall and includes at least one substantially straight portion. The straight portion has a lower edge as well as a substantially straight upper edge that is disposed at a second elevation less than the first elevation. The bottom wall connects the lower edge of the outer wall and the lower edge of the spout to form a channel between the outer wall and the spout.
