Abstract: A tee shaped housing for a swimming pool chlorinator apparatus has three ports, a water inflow port, a water outflow port, and a port into which an electrode assembly unit is sealingly disposed. The electrode assembly includes a plurality of alternating anode and cathode plates which extend into the flow of water in the housing, and the plurality of plates is connected to a source of electrical current. When the electrode assembly is removed for cleaning, a dummy plug is inserted into the port to seal the port so that the flow of water through the housing may continue while the plates are being cleaned.

Abstract: A wooden strip and a plurality of metal clips comprise or define a batten for securing tiles to a roof. Each clip includes a generally flat bottom and a pair of upwardly extending arms. Each arm includes an outwardly extending flange. Each flange includes at least a single barb extending upwardly for securing the clip to the wooden strip. The barbs are punched out of the flanges and extend into the bottom of the wooden strip to secure the clips to the wooden strip. The bottoms of the clips are flat to be disposed on the roof, with the arms supporting the wooden strip off the roof.

Abstract: Batten elements are made of plastic or metal, such as galvanized steel, galvalume, or aluminum. Several alternate embodiments of battens are shown, along with a schematic illustration of a punch process for making the metal battens of the present invention. The batten elements all include holes or tunnels for the drainage of water through the batten elements. The alternate embodiments are shown in cross section or end view.
