A game may include a game board having a player-piece pathway of connecting player-piece spaces, and a plurality of player pieces. The device includes at least one burner being mobile along a direction substantially parallel to the axis Z-Z and adapted to deposit, on the elongated element, a chemical substance for forming a preform, and at least one suction element arranged on the opposite side of the burner on a portion of a wall of the device on the opposite side of the gripping member from the burner. The JPEG encoder differentially encodes DC coefficients of the component blocks in an order that corresponds to the desired rotated image. Moreover, the closed-loop control system and capsule can be used to maintain an atmosphere with minimal oxygen around the vessel so as to reduce the oxidation of precious metals on the vessel. The headrest has a headrest body and a headrest bracket which are mechanically connected in such a manner, via a bearing part having a sliding bearing and a pivot bearing that a vertical displacement and a pivoting about a horizontal pivot axis arranged perpendicularly to the longitudinal axis of the vehicle are achievable.
