  • Patent number: 10385551
    Abstract: Devices, apparatus, systems and methods for preventing lightning surges from entering metal plumbing, such as copper plumbing through the outside water hose valves, so as to eliminate pipe leaks caused by lightning strikes. To use the invention, the installer removes existing metal valves, and clamps a durable high temperature resistant non-conductive pressure rubber heater hose to the exposed exterior end of the copper piping. The other end of the hose is clamped to a reducer and a water control valve, such as a spigot. The assembly interrupts electrical surges from lightning from passing into the metal exterior valves on the sides of buildings and houses, which can damage the inside metal plumbing, such as the copper plumbing in the buildings and houses.

  • Patent number: 9777489
    Abstract: An elevator trench drain includes a trench and a drain passageway. The trench has a base wall with peripheral side walls extending upwardly therefrom to define a trench volume therein. The drain passageway extends downwardly from the base wall of the trench and places the trench volume in fluid communication with a lower opening of the drain passageway. The drain passageway has a first section proximate the base wall defining a first cross-sectional area and a second section distal the base wall defining a second cross-sectional area. The second cross-sectional area is less than the first cross-sectional area and this reduction in cross-sectional area produces a head pressure that increases the flow out of the lower opening.

  • Publication number: 20100148488
    Abstract: A pipe, hose, or tube coupler fitting that has a male and a female adaption joint on one or all of its ends and a body that connects these ends. On the outermost end of the fitting body (10) is a female (14) joint that can connect to a male pipe end, and then immediately behind this female joint, is a male (12) joint. To do this, the body of the coupler fitting immediately behind the female joint is sized inside (16) diameter and outside (18) diameter, to the same size of its corresponding connecting pipes' inside diameter and outside diameter, and continues this size throughout a length (20) a minimum of its female joint length (28), thus becoming a male joint once said female joint is removed. Once said female joint is removed by cutting, unthreading or anyway removed, the male joint can be used. This new coupler fitting's end or ends are universal male or female, whichever is needed.

  • Patent number: 7549677
    Abstract: A device for sealingly linking two end pieces (24) of a fluid line system, comprises a casing part (1) and an inner part (13). The inner part (13) is arranged in a prefabricated arrangement within the casing part (1) in an axially displaceable manner and serves to fixate a sealing unit (21) that is detachably linked with the inner part (13) until an end piece (25) is inserted into the casing part (1) via an introduction area (3) and comes into contact with the inner part (13). When the end piece (25) is inserted, the inner part (13) is axially expelled from the casing part (1), whereby the sealing unit (21) is inhibited in its axial movement by an abutment (12) and remains within the casing part (1). The two end pieces can be sealingly linked while indicating the relative position of the end piece (25) coming into contact with the inner part (13) without requiring a separate handling of the sealing unit (21).

  • Patent number: 7350824
    Abstract: A drain fitting has a unitary body with a lower section and an upper section upstanding from the lower section. The lower section encompasses a space and is open to the drain line to be cleaned. The upper section has a side wall and an inner wall which forms a channel. The inner wall encompasses a through passage which is open to the space encompassed within the lower section. A line of a given diameter can thus be received and maintained around the side walls. Another line of different diameter can be received and maintained within the channel and lines of other different diameters can be maintained within the through passage.

  • Patent number: 7269537
    Abstract: The invention pertains to the sensing and measurement of infrasound (pressure variations with frequency content under 10 Hertz). The invention measures the infrasound pressure variations and then attenuates undesired contributions due to, but not limited to, changes in ambient fluid speed and changes in altitude of the sensing device. The undesired contributions are attenuated using an adaptive filter with the measurements of the change in ambient fluid speed and the change in altitude. This approach differs from existing applications of adaptive filtering in that the invention uses measurements of speed and displacement to improve a pressure measurement. This approach differs from existing methods for attenuating the affects of the wind on the measurement of infrasound in that it does not require the use of a large spatial averaging filter.

  • Patent number: 7165571
    Abstract: A dual pneumatic quick-disconnect coupler preferably includes a valve body, a sealing ball and two pipe tap sleeves. The valve body includes a ball cavity that retains the sealing ball. A pipe tap nipple extends from one side of the ball cavity and two threaded holes are formed through the other side thereof. A quick-disconnect plug is threaded into one end of the pipe tap sleeve and a ball seat is formed in the other end to receive the sealing ball. An air hose with a quick-disconnect coupler is attached to one of the quick-disconnect plugs. Air traveling through the air hose will force the sealing ball to seal the unused quick-disconnect plug. A second embodiment seals each quick-disconnect coupler with a spring loaded piston. A third embodiment seals each quick-disconnect coupler with a flapper valve.

  • Patent number: 6976710
    Abstract: A method and device for repair and replacement of pipe broken at a junction. The device includes a coupler having a female end and a male end. The female end of the coupler has an inside diameter that will accept snugly the removed end of the broken pipe. The male end has an outside diameter that will snuggly fit into a new junction. The method and device is normally used with PVC pipe. When PVC pipe entering a junction is broken near the junction, the junction may be removed by cutting back from the broken PVC pipe and cutting the remaining pipe where it enters the junction. A new junction can be replaced with the coupler inlapping the new junction and overlapping the pipe.
