Abstract: A wine bottle aerator that includes a power control box, a stopper means, a submersion rod, and an aeration element. The aerator is affixed in a wine bottle, or any bottle desired by a user, by the stopper. The stopper includes vents to allow air flow from the interior of the subject bottle into the atmosphere. In use, the aerator is used to aerate a bottle of wine as follows: The aerator is fitted into the opening of the subject bottle. The submersion rod extends the aeration element to a position near the bottom of the bottle, so that it is completely submerged. When the aerator is activated, the pump draws air in through the air inlet into the pump. The pumping action then forces the air out of the pump through the air outlet and into the submersion rod. The air flows through the submersion rod and into the aeration element. The air then flows outward into the wine through the air holes in the aeration element. Pressure is not increased to a dangerous level in the interior of the bottle due to the vents.

Abstract: Sweat collection capsule permitting quantitative collection of sweat, comprising a frame held immobile on the skin, a closure secured to the frame and absorbent material located next to the skin in a cavity formed by the frame and the closure. The absorbent material may be removed from the device by removing the closure from the frame while the frame is held immobile on the skin.

Abstract: A leveling apparatus for the precise level adjustment of a scientific instrument. A base member is provided having a hollow cylindrical shape. A table for supporting the instrument rests on the base and has a shaft portion extending below the table. The upper portion of the shaft fits tightly into the hollow portion of the base member whereas the lower portion of the shaft is machined to fit loosely. The lower portion of the shaft is provided with a groove cut around the circumference thereof. Adjusting screws are threaded through the hollow cylindrical portion and are adapted to enter the groove. By adjusting the screws, the lower portion of the shaft is moved in a vertical plane since the shaft is loosely fitted into the cylinder. The upper portion of the shaft which is tightly fitted into the upper end of the cylinder causes the cylinder to deform slightly providing a fulcrum point which allows the table to be leveled in response to the adjustment of the adjusting screws.
