  • Publication number: 20100326544
    Abstract: This disclosure is directed to an earthquake or shock responsive swing check valve, shutting off water in an earthquake. The device utilizes a common swing check valve whereby the internal parts are machined and retrofitted to be responsive to shock. The reacting parts are the valve door and a magnet. Thus the valve door is provided with a circular steel plate fastened connectably to the door. The magnet is positioned outside the valve and above the valve door, making a magnetic attraction between valve door and magnet, thereby keeping the valve door in open position. Upon a shock or earthquake, the magnetic attraction between the door and magnet is broken, shutting off the water supply. The device can be reset to open position with a simple screwdriver.

  • Publication number: 20040204178
    Abstract: This disclosure is directed to a wireless telephone charging adapter whereby the connecting parts are threaded. The threaded portions are aligned by positioning the starting point of two pairs of two threads. This device is connected is the same manner as the tightening of a screw to a nut. The aligned positioning of the threaded starting point enables the synchronized engagement of the two pairs of threads whereby in one half to one full turn, all four threaded units are simultaneously engaged. This disclosure also provides for reverse threads, inclined threads, machine threads and the like.

  • Patent number: 6756701
    Abstract: This disclosure is directed to an earthquake or shock responsive electric relay, shutting off electric power, or actuating the use of power in lights, motors, alarms or any electric device, which includes any electric device used to stop the flow of water, gas oil or steam. The device utilizes a common relay type design whereby its reacting parts are balanced between a weight and a spring, a relay centered between upper and lower contactors so that upon occurrence of an earthquake or other violent shock, the device cannot remain balanced, thus causing the relay to conduct the contactor. After the shock has subsided, the relay returns to the balanced-position which is equal centered distance between the upper and lower contactors. The sensitivity of the device is controllable.

  • Patent number: 6237291
    Abstract: A concrete block is provided for integrated use directly above the footing whereby the block has one unobstructed longitudinally extending single cell half the block depth. The remaining opposing cell is longitudinally unobstructed and horizontally divided, having a solid flat shortened base to provide a third cavity below the remaining cell whereby the third cavity is a downsliding horizontal unobstructed cell the full block length. Each end of the block of the third cavity are open to allow a continuous flow of liquid concrete in which a floor pour can be received into the third cavity which is also the lower remaining half-cell of the block. Wall and floor can be poured separately with end of floor entered directly into sides of lower block cavity. When the concrete hardenes, a non-unified wall and floor results with both conjoined in the same structure above the footing level.

  • Patent number: 6016633
    Abstract: A weight supporting device combined to a concrete footing form for assembling and filling concrete blocks and the footing form simultaneously is provided. Two symmetrical sidewalls combined with interlock fasteners provide strength to suspend on the form an entire wall of concrete blocks before and during the filling of the cells of the blocks and the form.
