Abstract: An assembly for covering the face plate and receptacle head of a wall-mounted electrical outlet has a cover plate with front and rear sides, and a plurality of prongs that extend from the rear of the cover plate to engage the receptacle. The cover plate is sized to cover the face plate of the receptacle and the receptacle when the prongs are so engaged. The plate has a rearwardly extending flange so that its rear surface fits flush against the wall when the prongs engage the receptacle. The flange has a frontwardly extending section that with the front side of the plate creates a front cavity. The cavity has a depth to receive a wall covering to allow a smooth plane to be created between the covering and the front surface of the front flange section.

Abstract: Electrically powered apparatus is provided with a remote primary control station from which energization of the apparatus is usually controlled, and a secondary control station, such as a jog control station, which is remote from the primary control station and close to the apparatus, from which energization of the apparatus may also be controlled. A single manual push button start control module may be mounted at either station, so that when the module is at the secondary station there is no start button at the primary station. A holding circuit provides for extended energization of the apparatus when the push button is momentarily depressed at the primary station, and there is a stop button at the primary station; while the secondary station has no holding circuit. The holding circuit is disabled when the module is mounted at the secondary station, so the apparatus cannot be energized by mounting a second identical start control module at the primary station.

Abstract: An apparatus and method for purifying water by the addition of a halogen such as iodine in a metered amount. Incoming water is divided into two branches, a first branch where the halogen is added and a second branch leading to a mixing tank where the halogen-water solution from the first branch is joined and turbulently mixed together. The fluid then passes into a main kill tank where the halogen-water mixture is held for at least one minute to allow the halogen to kill bacteria. The water-halogen mixture is then passed into a carbon-mesh filter to remove the halogen and any suspended or dissolved impurities to provide a purified, fresh tasting water.
