Abstract: An antenna has a parabolic reflector and a tubular exciter which is provided for illuminating the reflector. At least one waveguide supports the exciter and connects electrically to the exciter for the guidance of electromagnetic waves to the exciter. A mount serving for mounting and stabilizing the reflector has an extension which extends radially beyond the edge of the reflector and has a support arm which is bent in a direction towards a front side of the reflector and extends forward beyond it. A waveguide bearing the exciter is fastened to the support arm.

Abstract: A cartridge-type fountain pen is formed at its rear end with a reserve compartment for receiving a reserve ink cartridge or a liquid applicator reservoir whose applicator is designed to project through an opening end of the rear end of the barrel. A second cap can be pressed on this rear end and has a rear cap member spring biased into engagement with the reservoir and whose position is visible through a window in an outer cap member of this second cap so that the user can ascertain whether or not the liquid applicator is in place within the reserve compartment.
