Imidazopyridine compounds that contain amide functionality at the 1-position are useful as immune response modifiers. The ground clamp is arranged between the tilt hinge shaft and the steering column. The invention also discloses a production process for composite profiles which include the steps of providing resin and fiber, producing a composite compound, processing the compound through an extrusion system, extruding the compound through the die assembly to form the desired profile, cooling the profile and cutting it to length.
