With Means For Mounting And/or Positioning Relative To Siphon Chamber Patents (Class 137/152)
  • Patent number: 9498758
    Abstract: A dilution apparatus includes a container having an adjustable float-operated make-up valve wherein the make-up valve has an inlet end connected to a water supply tube and an outlet end connected to a fill tube inside the container. The make-up valve is connected to a float disposed inside the container. The water supply tube is connected to a reservoir that contains a concentrate. The water flow through the water supply tube siphons the concentrate, into the water stream and through the make-up valve to form a first dilution. A proportioner is connected to a water supply and to the bottom of the container. The water flow through the proportioner siphons the first dilution into the proportioner, thereby mixing the first dilution with water to form a final product having a predetermined dilution ratio.

    Abstract: An oil from water separator has an oil disengagement chamber adapted to receive an oil and water mixture and retain it for a sufficient time in a relatively undisturbed state so that oil in the mixture floats to the top of the mixture. This results in a substantially oil free volume of water having a layer of oil derived from said oil and water mixture floating on the surface of the mixture. The oil disengagement chamber is partially separated from an effluent water chamber by an under flow baffle which ducts said substantially oil free volume of water to the effluent water chamber. The oil disengagement chamber has a low liquid level which is higher than the under flow baffle. The outflow of the substantially oil free volume of water from the effluent water chamber is limited to a rate of outflow which is a function of the head of the liquid in the effluent water chamber.

  • Patent number: 5806301
    Abstract: Pressure sensors are placed at axial locations in the isolator of a scramjet or ramjet. An engine fuel control produces calculated pressure values for the those locations from a stored function. As the engine operates, the pressure signals from the pressure sensors are compared with those pressure values for each sensor location and the stored function is adjusted so that the curve of the calculated pressures closely matches the measured pressures within stored upper and lower pressure limits for each pressure sensor location. From the adjusted function. the shock system is located. Fuel flow is controlled to maintain the shock system at a desired location in the isolator. Faulty pressure sensors are detected from a signal that manifests the difference between calculated and actual pressure at each pressure sensor.

The transfer conduit is initially filled with water and is elevated so that a portion of the conduit is above the siphon height of water at atmospheric pressure with the open ends of the conduit submerged below the respective pools. Using solar heat to create a temperature differential in the transfer conduit, desalinated water vapor is transferred across a partial vacuum volume formed in the transfer conduit. Salt water is replenished in the transfer conduit from an elevated storage tank, resulting in a constant reduced salt concentration and transfer vacuum at the evaporation surface, reducing the need to repeatedly lower, recharge and raise the system. Various mechanisms are provided for improving heat transfer and condensation and for eliminating movement of the transfer conduit.

The railway tank car has a generally curvilinear inner wall, and the eduction pipe is provided with a shape corresponding to the generally curvilinear inner wall and is supported in proximity thereto. This enables the eduction pipe to readily accommodate radial distortions of the railway tank car during transport. In addition, all (or substantially all) of the fluid commodity in the railway tank car can be withdrawn through the eduction pipe since the lower end thereof may be positioned in close proximity to the bottom sump without concern for radial distortion or deflection of the tank car.

  • Patent number: 4865268
    Abstract: A construction is provided to aerodynamically affect a jet engine nacelle in its intake lip area primarily by forming and pivotally arranging flaps on a radially outer circumferential sector of the intake lip such that from a first extreme position, in which they are adapted to a cruise lip geometry, they can be moved into a second extreme position, in which they radially expand the outer contour of the intake lip while providing and exposing air blowoff ducts with their rear side, said ducts terminating at the outer wall of the nacelle at essentially a tangent therewith. Further air injection flaps are also provided in certain embodiments for forming air injection ducts through the intake lip walls during certain engine operating conditions.

  • Patent number: 4651767
    Abstract: A conveyor belt dewatering system in which a siphon tube or pipe is vertically moveable on a tubular support whereby selectively its inlet is lowered into a conveyor belt. Counterweights counter the weight of the siphon tube, these weights being positioned in the tubular support. A source of service water is turned on by a float switch sensing water is the conveyor belt, the service water being used to submerge the weights and lessen their effect and at the same time be supplied to the siphon tube to increase its weight, whereby a siphon tube is lowered into the conveyor belt and siphoning from it commenced.

  • Patent number: 4523603
    Abstract: A variable air inlet includes an air intake duct with upper ramps, an air inlet bottom spaced below the ramp and a movable air scoop lip pivotally secured to the end of the air inlet bottom closer to the opening into the air intake duct. The air scoop lip is pivotally displaceable through two angular operating ranges, a wider one in the subsonic/transonic range and a narrower one in the upper supersonic range. Various control members including computers are used to control the position of the lower air scoop lip. The movement in the subsonic/transonic range is effected in response to the flight machnumber and the aircarft angle of attack based on a given control law. The control in the supersonic range is established in response to a variable demand pressure ratio between the static pressure above the upper ramps and the free stream total pressure, with the variable demand pressure ratio being a function of the actual air scoop lip position.

  • Patent number: 4418708
    Abstract: A two-dimensional, unidirectional oblique air impact diffuser is used as an air inlet for a gas turbine jet engine for aircraft. The air inlet includes an upper rigid air inlet ramp and an air inlet bottom spaced below the ramp. An air scoop lip is pivotally attached to the air inlet bottom so that it can be pivoted from a standard setting point downwardly away from the air inlet ramp and also from the standard setting point toward the ramp. The pivotal displacement of the air scoop lip is a function of the aircraft angle of attack and the flight Mach number. The angular displacement of the air scoop lip from the standard setting point increases downwardly as the aircraft angle of attack increases and decreases as the Mach number increases.

  • Patent number: 4255938
    Abstract: A converging/diverging venturi assembly positioned in a subsonic fluid flow stream for producing a supersonic flow velocity in the downstream diverging section with a pressure pickoff system that is located adjacent a minimum static pressure location just prior to a point where shock waves begin to form. The low pressure in the supersonic region in front of the shock wave may be utilized for reducing the boiling temperature of a fluid in a boiler by porting a tube from the low pressure venturi to the boiler, thus improving the heat transfer characteristics of the boiler where the boiler is used for a heat sink for heat sources in a mobile vehicle.
