Abstract: A submersible well fluid system for operating submerged in a body of water may include an electric machine and a fluid end. The electric machine includes a rotor and a stator residing in a first housing at specified conditions. The fluid end may include an impeller and be coupled to the electric machine. The submersible well fluid system may also include an adjustable speed drive for the electric machine in the housing. The submersible well fluid system may also include a chemical distribution system for supplying treatment chemicals to the submersible well fluid system, a barrier fluid supply system for supplying a barrier fluid to the submersible well fluid system, and a pressure management system.

Abstract: A water distribution pipe comprises an elbow formation along its length, an aperture-defining formation defining an aperture in a radially distal wall of the elbow formation along a radius of the curvature of the elbow, and an openable closure that is mounted or mountable to the aperture-defining formation and that closes the aperture.

Abstract: Method and device for metering a medium from at least one storage tank by a metering device, which has a piston pump, which defines a working chamber with a cylinder and a piston, wherein in a first method step a determined filling quantity of a medium is conveyed via an inlet valve into the working chamber and the determined filling quantity is greater than the quantity to be metered and, in a second method step, the piston reduces the working chamber in size enough that only the quantity to be metered remains, wherein the excess medium flows out of the working chamber, wherein the excess medium flows via the inlet valve back into a ring line, which is connected in a medium-conducting manner to the storage tank and is arranged outside the working chamber.

Abstract: A rainwater collection and diverging system includes a housing that has a bottom wall and a perimeter wall. A door is positioned in the bottom wall. A hinge hingedly couples the door to the bottom wall and a biasing member is attached to the door and biases the door in a closed position. Fluid in the housing may flow outwardly through the bottom wall when a biasing action of the biasing member is overcome and the door is moved to an open position. An outlet is fluidly coupled to the housing. A downspout has a bottom end extending into the housing. A conduit is fluidly coupled to and extends between a free end of the outlet and a fluid receptacle. Water flowing down the downspout is directed into the conduit until a force of the water flowing down the downspout overcomes the biasing action and opens the door.

Abstract: A method and apparatus for preventing blockage of a water flow path from a gutter of a building through a downspout includes a receptacle which is rotatably supported beneath the gutter. The receptacle is movable between a collecting orientation and an emptying orientation under the influence of the weight of water and debris conducted from the gutter to the receptacle when the receptacle is in the collecting orientation. The receptacle includes a compartment having an outlet through which water passes prior to collection of debris in the compartment. As debris collects in the compartment and at least partially blocks the outlet so that water also collects in the compartment, the combined center of gravity of the receptacle and the water and debris in the compartment moves from one side of a vertical plane containing the axis about which the receptacle rotates to the opposite side of the plane. As this occurs, the receptacle is rotated from the collecting orientation to the emptying orientation.

Abstract: An apparatus for supplying an accurately measured volume of liquid, comprising a vessel filled with the liquid, a cylinder loosely and slidably fitted into the vessel from above, and a sealing box at the top of the vessel sealing the vertical motion of the cylinder. The sealing box has a liquid discharge port at a bottom edge. A drive shaft, preferably screw driven, moves the cylinder vertically downward.

Abstract: This invention relates to a device for the constant replenishment of an animal dipping bath, or for use in any situation where it is desired to have a concentrate diluted with a liquid with little or no liquid supply pressure.The device consists of a two-component rocking-pan arrangement 8 and 9 for receiving and discharging the mixture and a metering arrangement for discharging concentrate in the pan. The metering arrangement consists of a double acting single piston and cylinder pump, linked to the pan, and comprises a single piston 22, and a single cylinder partitioned by the piston into 2 chambers, 25 and 26 each chamber being capable of receiving and discharging quantities of concentrate. The arrangement of the pump is such that when one chamber is discharging concentrate into the pan the other is receiving concentrate from the supply line, and concentrate is delivered to that one of the two components which is about to be filled with diluent. The device is particularly useful for sheep-dipping purposes.

Abstract: A water treatment and storage system includes a reverse osmosis treatment unit having an untreated water input line, a treated water output line and a bleed water output line. An expandable container, compressed by a spring arrangement, is provided for storing treated water. A container valve, connecting the reverse osmosis treatment unit and the expandable container, terminates the flow of treated water to the container when a predetermined quantity of water has been accumulated therein. The container valve further includes a bleed valve arrangement connecting the bleed water output line and a drain line. The bleed valve arrangement terminates the flow of bleed water to the drain line after the container has accumulated the predetermined quantity of treated water.
