Abstract: A toilet-tank discharge valve has a main-valve body that can be lifted off of its face, by release-activating an auxiliary valve with an activating mechanism, as a consequence of negative water balance in an associated discharge compartment. A supplementary auxiliary valve is associated with the discharge compartment and opens at least briefly as a result of discontinuance activation of the activating mechanism, producing a positive water balance in the discharge compartment until the main-valve body closes. A valve of this type, with an auxiliary valve, makes it possible to discontinue the flushing process ahead of time. A shift mechanism in the connection between the activating mechanism and the supplementary auxiliary valve shifts the supplementary auxiliary valve from whatever limiting position it happens to be in into the opposite limiting position in response to a discontinuance activation.

Abstract: A skimming device for removing debris from the water surface of a swimming pool is formed from a skirt member of net material. Buoyancy material is mounted on the one edge margin of the skirt member and weights are mounted on the opposite edge margin of the skirt member. Thus, the skirt member is a vertical orientation when it is in the water of a swimming pool. One or both ends of the skirt member is provided with a bar to which a handle can be releasably connected. Movement of the ends of the skirt member relative to each other along the peripheral margin of the swimming pool causes the skirt member to be moved in a manner to skim the entire water surface and eventually to form a loop which traps debris which normally floats on or near the surface of the water. Then, by pulling the skirt member while it is in the form of a loop out of the pool, the debris is removed quickly and easily from the swimming pool itself. The skirt member can then be washed with a garden hose and air dried for use at a later time.
