Abstract: A household water reservoir includes a reservoir body having a water inlet, a water outlet, and a water chamber communicating between the water inlet and the water outlet. The water inlet is operatively connected to a water inflow of the household water piping system. The water outlet is operatively connected to a water outflow of the household water piping system. Accordingly, the water chamber is adapted for reserving a predetermined amount of water when the water flows from the water inlet to the water outlet, in such a manner that the reservoir body enables the water being stored in the water chamber in fresh by keeping the water moving from the water inlet to the water outlet during daily water usage.

Abstract: A panel device, particularly a sign board is made up of at least one channel-section display member having a plain front face of predetermined width force fitted onto a support member, which is an extrusion-formed item, by interaction between the legs of its channel and projections on the support. The projections on the support are arranged in pairs and the pairs are regularly spaced apart along the support. The spacing between pairs is the same as increments in width as between different display members so that display members of the same or different widths may be fitted to the support member. The plain face of the display member is to bear indicia or the like.
