Tank With Movable Or Adjustable Outlet Or Overflow Pipe Patents (Class 137/577)
  • Patent number: 9458923
    Abstract: A lubrication system includes a reserve housing configured to retain a lubrication fluid. A supply line in fluid communication with the reserve housing is configured to provide pressurized lubrication fluid to the reserve housing. An overflow tube has an overflow port, the overflow tube being configured to prevent the volume of the lubrication fluid from exceeding a certain amount. A metering jet is configured to allow the lubrication fluid to flow from the reserve housing onto a component, such as a bearing, in the gearbox at a predetermined rate. The metering jet provides flow of the lubrication fluid onto the bearing even when the supply line no longer provides pressurized lubrication fluid to the reserve housing.

  • Publication number: 20150083234
    Abstract: Diaphragm joint and convolutions, bottom screen diffuser, air stern, cap, and diaphragm restrictor systems for a pressure vessel are disclosed. A convoluted diaphragm divides the vessel into a pair of sealed chambers. The convoluted geometry of the diaphragm minimizes stress on the diaphragm at maximum displacement conditions. An H-ring, with or without being over-molded by the convoluted diaphragm, may be configured to receive end portions of the tank liners. A bottom diffuser, coupled to an inlet of the vessel, diffuses and mixes water flowing into and out of the vessel and drains water out of the vessel. Fiberglass windings surround and lock the tank liners in tension. The cap system includes a valve cap that engages an air stem. An outer cap covers a recess of the vessel and includes a hollow cavity that receives the valve cap. A diaphragm restrictor limits upward movement of the diaphragm within the vessel.

    Abstract: Improvements are disclosed for liquid flow drainage control in gravity type systems such as sewage septic tank systems. A plastic cap which is insertable into the ends of the drainage pipes that project into a distribution box is formed with an end face and a cylindrical body. The end face is generally circular having a larger diameter than the outer diameter of the drainage pipes into which the cap is to be inserted. The outer periphery of the end face is provided with an interdigital or scalloped pattern to facilitate easy gripping even in the most adverse conditions. The end face is further provided with an eccentric discharge hole which is located along a diameter of the end face so that the hole is always some distance from the interior surface of the cylindrical body so that the hole forms a weir to the inlet of the drainage pipe into which the end cap is inserted. The eccentric hole is provided with an outwardly projecting flange which, in cooperation with a spirit level, is used for rough leveling.

  • Patent number: 4719771
    Abstract: Apparatus for applying liquid to a running yarn in a textile machine comprises a hollow body providing a manifold for the liquid and an elongate tube extending horizontally across the manifold. The tube is retained in a bore in the body by a yarn guide which is detachably secured to the body and the bore in the tube communicates with a groove yarn path provided by the yarn guide via a bore in the yarn guide of larger diameter than the bore in the tube. The constant supply of liquid to the yarn is provided by the controlled flow of liquid along the tube whose length is at least 100 times the diameter of the bore therein. A height adjustable weir in a liquid supply tank supplies liquid to the manifold at a predetermined pressure. The yarn path has a plurality of yarn contact points to ensure complete application of liquid by the yarn.

  • Patent number: 4700734
    Abstract: The present invention relates to water collecting and spring box and gauging system and water holding tank wherein the spring box is designed to receive and collect water from a source such as a spring. Once collected in the spring box, the water is filtered prior to being directed to a water holding tank that is normally stationed near a point between the spring and location of ultimate use. The spring box includes a water inlet, a drain, and a supply outlet. The flow rate of water from the spring box is controlled by varying the height of the water level maintained in the spring box and by selectively sizing and spacing openings formed in a vertical water filter that is communicatively connected to the supply outlet.

  • Patent number: 4672690
    Abstract: A sewage treatment system includes a toilet, vacuum tank, and vacuum pump. The toilet has a discharge portion at its bottom, and a foot operated valve selectively allows, or blocks, passage of water and waste from the toilet bowl into the discharge. When the valve is opened in rushing air forces waste and water from the bowl at high velocity so that the waste fragments. The vacuum tank is connected to the toilet discharge and is disposed directly below it, and has an outlet at its bottom and a dome-shaped baffle, with side openings, covering the vacuum tank outlet. A vacuum switch is operatively connected to the vacuum tank and controls the vacuum pump. The pump is operatively connected by a conduit to the vacuum tank outlet. The vacuum tank outlet has a diameter about half the size of that of the vacuum tank inlet.

  • Patent number: 4428145
    Abstract: A shrimp bait container is disclosed which includes a plurality of stacked trays, with each tray storing live shrimp bait in a water medium. Each tray is substantially a frusto-pyramidal shaped housing having four sides and a bottom, composed of a relatively thick, thermally insulating material. The sides extend upwardly and outwardly from the bottom and are inclined so that the outer surfaces thereof for an upper one of the trays will mate with the inner surfaces thereof for an adjacent, lower one of the trays, forming an enclosed volume for storing the water medium containing the shrimp bait. The bottom of each tray has a perforation therethrough. An adjustable water depth controlling pipe is slideably mounted in substantial vertical orientation in the perforation in the bottom of each housing, having a height above the bottom which can be vertically adjusted and through which water within the enclosed volume may overflow, thus defining the depth of the water.

  • Patent number: 4413914
    Abstract: Oil sludge (15) formed within a storage container (10) is removed by penetrating tubular lances (20) into the sludge body (15) and then pumping dispersant chemicals borne by a water jet through the lances (20) into the sludge body (15) with continuous drawing off and recirculation of emulsified fractions under pressure. The sludge body (15) breaks down both physically and chemically to form a pumpable fluid which is drained and mixed with a larger volume of liquid oil to allow dispersion of the hydrocarbonaceous content of the emulsified fluid as a suspension in the oil volume allowing the water to settle out of the mixture, the settled water layer being thereafter drawn off. This oil mixture is then processed in the process plant. The dispersant chemicals emulsify or form coloidal suspension or solution of the hydrocarbonaceous content of the sludge body (15) in water.

  • Patent number: 4363621
    Abstract: An oil burner of the type of pumping up a fuel oil is disclosed which has a first oil level setting means of an airtight type having an overflow pipe means constantly immersed at the lower end thereof in a fuel oil to be pumped up to the first oil level setting means and has a second oil level setting means disposed below the first oil level setting means and directly connected to a fuel oil supply tank. A fuel oil supplied from the second oil level setting means is drawn up to the first oil level setting means by a pumping-up means and subsequently supplied through a supply pipe to a combustion means. The level of a fuel oil in the first oil level setting means is kept constant at a position above the outlet end of the supply pipe. The overflow pipe means may be movable in the vertical direction so as to vary only the supply rate of a fuel oil.
