Abstract: A marking device is used in conjunction with an electrical outlet box to mark a wall panel with the exact and precise location of that outlet box so the panel can be cut to accommodate such outlet box. The marking device includes an I-shaped body having ears on each corner of a rectangular shaped central body. An anchoring element is attached to each ear and extends far enough to fictionally engage the outlet box, and a biplanar arrow-shaped marking element is also attached to each ear.

Abstract: A portable vehicle washing device is used to spray liquid, such as water or a water/soap mixture onto a vehicle, such as a car, during a washing process. The device can be adjusted in several planes to accommodate various vehicles and is used with a garden hose to keep the vehicle wet during the washing process. A telescoping length-expanding joint and an accordion orientation-changing joint are included in a sprinkler pipe and the device includes bumper-attaching hooks as well as ground-engaging supports and rests that engage the top of the vehicle so that the device is securely mounted in place during the washing process.

Abstract: A float controlled siphon discharge valve mechanism operates to drain water from a swimming pool cover, and includes a lever arm attached at one end to a hinge and having a float on the other end so that the lever is of the second or third type. A closure control is also included to sense for the presence of water immediately adjacent to the drain opening, and includes a spring loaded control arm connected to the lever arm to force the lever arm into a drain occluding position even if the float does not move that lever arm into such a position in order to ensure that the siphon is not broken even in the event that the float operation malfunctions.
