Labyrinth seals are also found on pistons, which use them to store oil and seal against high pressure during compression and power strokes, as well as on non-rotating shafts. In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some limited contact-sealing action that creates the seal.
Tandem seal with intermediate labyrinth; Double opposed seal - Used when the processed gas is abrasive (like hydrogen) and lower pressure designs. All designs use buffering with "dry" gas, supplied through control and purification systems. All Dry Gas Seals need additional protection from the process and the bearing lubrication sides of the seal

[15]In Orkney lore, selkie is said to denote various seals of greater size than the grey seal; only these large seals are credited with the ability to shapeshift into humans, and are called "selkie folk".
Humans have two otolithic organs on each side, one called the utricle, the other called the saccule. The utricle contains a patch of hair cells and supporting cells called a macula. Similarly, the saccule contains a patch of hair cells and a macula. Each hair cell of a macula has forty to seventy stereocilia and one true cilium called a kinocilium
It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. [2] [3] A core component of the cochlea is the organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea.
In Greek mythology, the Minotaur [b] (Ancient Greek: Μινώταυρος, Mīnṓtauros), also known as Asterion, is a mythical creature portrayed during classical antiquity with the head and tail of a bull and the body of a man [4] (p 34) or, as described by Roman poet Ovid, a being "part man and part bull".
