Abstract: A textile layered construction has a textile outer layer, a textile inner layer and an absorbing component, whereby line-shaped connections between the outer layer and the inner layer are designed as a laser welded joint, forming chambers fillable with insulating material between the welded joints. At least one line-shaped welded joint connection includes an interruption separating the line-shaped welded joint connection into two line-shaped welded joint connection parts.

Abstract: A dental handpiece includes a turbine arranged in a handpiece head for rotating a tool, wherein the turbine is supported by slide bearings or roller bearings arranged on the side of the rotor or turbine facing the tool and on the side of the rotor or turbine facing away from the tool. The handpiece head includes an air duct for the propulsion air and a return duct for the returned or used air. At least one opening in the turbine chamber wall in the area near the axis is connected through a connecting duct to the return duct.
