Abstract: A nail drill is configured to create a hole in a nail, such as a fingernail or toenail. The nail drill has a shaft extending from a handle. A tip is configured on an end of the shaft not coupled to the handle and has one or more cutting sections configured to cut into a nail. The nail drill may be utilized for relieving a pressurized area underneath a nail, such as bodily fluid that may have collected due to a prior trauma or other condition. The method for relieving the pressurized area includes positioning the tip onto an outer surface of the nail. The shaft may be rotated so that the tip turns and cuts a hole in the nail. The shaft is rotated until a hole is created through the nail enabling the bodily fluid to pass from the pressurized area through the hole, thereby relieving the painful condition.

Abstract: A combination of a top, and a base that has a flat surface upon which the top may be spun and a cavity for storing the top when the top is not in use. The top has a pointed end upon which it is spun, an opposite handle end and an intermediate disk-like mass. The surface has an upstanding peripheral ridge to keep the spinning top on the surface. The cavity is sized to receive the top pointed end first. An O-ring is held in a groove in the cavity surface and extends into the cavity. When the top is pushed into the cavity, the disk engages the O-ring and is resiliently held in place. The top is removed for use by reaching fingers into the cavity opening, grasping the handle and withdrawing the top. A base having a number of these cavities may also be provided for storing a number of the tops.

Abstract: A turbocharger, supercharger or like apparatus for delivering pressurized airflow to an engine, with a housing and valve structure associated with the compressor for permitting selective recirculating flow from the high pressure compressor exhaust to the inlet thereof. A diaphragm acts both as the valve and to define a signal chamber.
