Abstract: A refillable reservoir, particularly an ink converter for a fountain pen, has a cylinder in which a piston is slidable, and an actuating device for displacing the piston for refilling the ink chamber. Without needing to be detached from the piston, the actuating device can be stored substantially within the length of the chamber. The actuating device can be a rod which is disengageable from and slidable through the piston. Alternatively the actuating device can be a flexible ribbon coupled to a sleeve slidably mounted on the cylinder.

Abstract: A connector for tapping a coaxial cable has a housing (2) formed of two generally identical housing parts made of a plastics material. A longitudinal bore (4) extending through the housing (2) receives a cable to be tapped. Facing surfaces of the housing parts are arranged to abut and each has a generally U-shaped channel (14) therein which defines the bore (4) upon abutment. The housing parts also form a further bore (16) which extends transversely to, and communicates with, the first bore. An elongate probe (20) to contact the core of the coaxial cable is received within the transverse bore (16). Two contacts (32), for contacting outer conductors of the cable, are held in the first bore, one on either side of the transverse bore. Because the housing parts completely define the two bores it is ensured that reliable connections to the coaxial cable are always made.
