Abstract: Disclosed is a method for manufacturing free-standing cladding tubes with multi-layer structures. According to the method, a cylindrical mandrel substrate defining a hollow cylindrical inner space is provided. A first cold spray powder metal is selected. The cylindrical mandrel substrate is rotated and the first cold spray powder metal is applied to an outer surface of the cylindrical mandrel substrate to form a first layer. The cylindrical mandrel substrate is removed.

Abstract: A seat damper assembly for a chair includes a rubber element having a through hole and a bracket seat having a major surface with a raised portion around a perimeter of the major surface. A support bracket is configured to be coupled with the bracket seat such that the raised portion abuts an outer edge of the support bracket. A side of the support bracket opposite the bracket seat is shaped to receive a portion of a chair frame assembly. A fastener, disposed in the through hole in rubber element, is configured to couple with a seat pan to secure the seat damper relative to the seat pan.
