Abstract: A combination toilet seat and bidet adapted for use on conventional toilets, comprising a seat portion and a cover portion hingedly-connected to each other to form a unit which is preferably pivotably-connected to a mounting member which is adapted to be connected to the seal-mounting holes of a conventional toilet. The cover portion preferably includes a water spray attachment which is adapted to be connected to a water source. The attached unit is convertible between normal seat-down position and cover-under or bidet position by lifting the unit from the front, pivoting it 180.degree. on the mounting member and then lowering the front of the unit so that the unit rests on the toilet in inverted or upside down position.

Abstract: A carbon ring seal for a shaft rotating at high speed is capable of preventing high temperature, high pressure gas from entering the oil system. The carbon seal is constructed so that at ambient temperature it works as a controlled gap seal, but when the seal runner reaches its full thermal growth the seal then functions as a positive contact seal. The carbon seal ring is not pinned against rotation, but rotation is limited by means of an integral drag pad. The seal housing is provided with a plurality of calibrated holes for predetermined internal pressurization and cooling.

Abstract: A carbon ring seal for a shaft rotating at high speed is capable of preventing high temperature, high pressure gas from entering the oil system. The carbon seal is constructed so that at ambient temperature it works as a controlled gap seal, but when the seal runner reaches its full thermal growth the seal then functions as a positive contact seal. The carbon seal ring is retained by an anti-rotation pin extending through a slot in the ring. The carbon ring has a single fracture at the slot. The seal housing is provided with a plurality of calibrated holes for predetermined internal pressurization and cooling.
