  • Patent number: 10731324
    Abstract: HYDRANT ARMOR is an enclosure that protects fire hydrants from all weather and environmental conditions and has light reflective features incorporated on the exterior of the enclosure to ensure its visibility in darkness. When fitted with a tall reflective post, fire hydrants can be located even when they are covered in snow. Hydrant valves and hose connection caps are protected from natural elements and corrosion while they are within the hollow enclosure. The enclosure is suspended off the ground so as not to become frozen to the ground, and is held in place with an integral bracket that is attached to the hydrant. The open bottom of the enclosure fits over and locks onto the bracket and can be removed from the hydrant without tools. The conical shape of the enclosure, tapered at the bottom, will prevent the enclosure from binding in deep snow.

  • Patent number: 10246675
    Abstract: A cartridge sealed from ambient air is used to send a liquid without causing the liquid to contact the fluid inside the cartridge. Inside of the cartridge 1 sealed from ambient air are provided chambers that send and receive reagents, and an elastic body membrane 51 is attached to the bottom surface. The cartridge main body 51 does not have a groove or anything else that becomes a channel, and the membrane 51 is not bonded to portions that become channels. A channel, not formed in a normal state, is formed upon deforming the membrane 51 under air pressure in the unbonded portion, and the fluid is moved inside. A valve function is provided at an inlet of each chamber, and the fluid is internally moved in any direction with channel deformation.

  • Patent number: 10024441
    Abstract: Provided is a refrigeration valve having a valve body having an inlet, an outlet, and a flow passage defined therebetween, an expansion valve in the flow passage, a first hand valve between the inlet and the expansion valve, and a second hand valve between the outlet and the expansion valve. The first and second hand valves are provided at a top of the valve body and are movable in a first direction for preventing fluid flow through the flow passage. By providing the first and second hand valves at the top of the valve body rather than at a bottom of the valve body, valve life is increased and the valves are not prevented from operating due to particulate build up in the valves.

  • Patent number: 6653245
    Abstract: A method for liquid phase deposition, including the steps of providing at least two raw materials from at least two supply devices of a saturation reaction system into a mixture trough and stirring until saturation occurs, filtering out unnecessary solid-state particles, and providing saturated and filtered liquid into an over-saturation reaction trough of a steady-flow over-saturation loop reaction system and stopping the saturated and filtered liquid when the over-saturation reaction trough is filled and the saturated and filtered liquid over-flows into a liquid level control trough to a pre-determined level. The method also includes the steps of providing a substrate in the over-saturation reaction trough, providing reactants from at least two supply devices into the over-saturation reaction trough, and depositing a thin film onto the substrate when the saturated liquid becomes over-saturated.
