  • Patent number: 8439062
    Abstract: A system and method for detecting water in locations in homes and buildings where it should not be present, and responding by terminating water inlet access to plumbing in said home or building or the like and optionally operating a dump valve, in combination with an approach to periodically testing system operability and providing a signal upon a component performing a predetermined number of operations. The method can further include the monitoring of signals and responding with maintenance and/or replacement.

  • Patent number: 8402984
    Abstract: The present invention is a system and method for detecting water in locations in homes and buildings etc. where it should not be present, and responding by terminating water inlet access to plumbing in the home or building etc., and by opening a pressure dump valve to relieve leak promoting pressure remaining in the plumbing.

  • Patent number: 5125576
    Abstract: A container rinse system for a portable sprayer includes a nozzle adapted to be mounted adjacent the fluid inlet opening of the main fluid tank of the sprayer at a position for insertion into the open mouth of a container situated to pour chemicals into the fluid inlet opening. The nozzle is connected to the main fluid pump for discharging fluid from the main tank through the nozzle for unlimited initial rinsing without dilution of the fluid in the main tank. The nozzle may alternately be connected to a clean water reservoir by a valve for a brief final rinsing requiring minimum fresh water supply on the sprayer. The valving preferably includes a safety valve actuated by a fail-safe switch to prevent fluid delivery to the nozzle, except when a container is properly situated over the nozzle for rinsing.

  • Patent number: 4729490
    Abstract: The automatic touch actuated door opener includes an elongated flexible tension member having one end connected to a door and the other end connected to a tension member take-up device. The door is biased to its closed position for maintaining tension in the tension member when the door is moved to its closed position. A switch in contact with the tension member senses decreased tension due to external touching pressure against the door and actuates the take-up device to automatically open the door. A time delay switch causes the take-up device to allow the door to return to its closed position after the preselected time interval. An alternate embodiment includes a pair of limit switches which are sequentially engaged and released in response to increased and decreased tension respectively in the tension member.
