Abstract: A sealing apparatus for an anatomical part comprises a support collar that comprising an annular body. An elastic sealing membrane is positioned within the support collar. The sealing membrane defines an annular sealed chamber having a given inner diameter in a natural state of the elastic material. A port in the sealing apparatus is in fluid communication with the chamber. The port is adapted to be in fluid communication with a device for reducing pressure in the chamber to increase the given inner diameter of the chamber in a collapsed state, so that an anatomical part may be inserted into the sealing apparatus. A sealing apparatus and accessories are also provided, as is a method for sealing an anatomical part in an inner cavity of an accessory.

Abstract: For separating cooled and uncooled water in a refrigerated bottled drinking water cooler well, a floating receiving reservoir floats in the well and has an upper edge resting on or above a surface of water in the well, the reservoir having an open top surface and being supplied by uncooled water from a mouth of a drinking water bottle turned upside down and submerged in the reservoir. A conduit communicates the reservoir with a first water outlet as the floating reservoir moves up and down in the well. Drawing water from the first outlet causes a level of uncooled water in the reservoir to be lowered until air enters the mouth and water from the bottle is emitted into the receiving reservoir. Drawing water from a second outlet connected to the well causes a level of the surface of water in the well and thus of the uncooled water in the floating reservoir to drop until air enters the mouth and water overfills the receiving reservoir pouring over the upper edge into the well.
