Abstract: A holder for a roll of disposable towels has a base and an upstanding member extending upwardly from the base to be inserted into the hollow core of a roll of disposable towels or the like. A suction cup is held to the underside of the base for holding the base securely to a surface such as a counter top upon removal of the towels from the roll. The suction cup has upstanding portions engaging the underside of the base to enable the suction cup to be depressed by movement of the holder downwardly. In preferred form, the base has an opening for receiving a tab connected to the suction cup for releasing the suction cup from the surface.

Abstract: A universal adaptor plug is disclosed as an encased arrangement of elements, which includes a single rotatable knob for attachment to and for rotation of a cam axis for mounting at least three cam elements. The front face of the casing defines openings through which project multiple sets of plug pins movable by the cams and cam followers. Each set of plug pins is attached to a base which causes retracting of the plug pins by the base's attachment to retracting springs. The continuous unidirectional turning of the knob, in turn, projects and enables retraction of a set of plug pins for a certain country or group of countries.
