  • Patent number: 11040376
    Abstract: Spray apparatus and uses thereof are described herein. A vacuum spray nozzle apparatus may include a first tube in fluid communication with a fluid source, a rotor coupled to the tube, a conduit in fluid communication with the passages of the first tube, and a second tube coupled to the conduit, the second tube being in fluid communication with a vacuum source. The rotor is in fluid communication with the pressurized fluid source. The conduit is substantially arched or angled such that an outlet of the conduit is offset a radial distance in a radial direction from the rotor axis, and when pressurized fluid is ejected from the outlet, during use, rotates the conduit. The vacuum spray nozzle apparatus is configured to remove components from a material through the second tube when a pressure of the system is reduced using the vacuum source.

  • Patent number: 10792525
    Abstract: A portable fuel container configured to prevent liquid fuel contained therein from being entirely emptied from the container. The amount of liquid fuel retained in the container can be sufficient to maintain a fuel-to-air ratio in the container at a fuel-rich level that prevents combustion within the container if the container were to be placed near an ignition source or if an ignition source were to somehow enter the container. The container can also include other safety features such as, for example, a flash suppressor located at the fill opening, an extra wide fill opening, and/or an easily controllable dispensing spout. When a flash suppressor is employed, the perforations in the flash suppressor can be configured to retain fuel therein after fuel has been dispensed from the container and the flash suppressor is no longer submerged in fuel.

  • Patent number: 10688421
    Abstract: A strainer for filtration in an oil circuit of a turbine engine, in particular a multi-flow turbojet engine, is housed in a bore of a lubrication assembly. The oil serves to lubricate and cool mechanisms of the turbine engine. The strainer includes a filtering portion as an angular tube portion and a holding structure for the filtering portion. The structure forms a thickening and exhibits rings and structural posts. A magnet is added in a socket formed by the structure. The structure and the filtering portion are integral and are produced by additive manufacturing, which simplifies production. The application likewise relates to a method of producing the strainer.

  • Patent number: 9955709
    Abstract: A method for washing fish flesh to remove water soluble sarcoplasmic proteins includes producing a mixture by combining wash water with fish flesh having sarcoplasmic and myofibrillar proteins, wherein the wash water removes some of the sarcoplasmic protein from the fish flesh; depositing the mixture on a screen separator. The wash water having sarcoplasmic proteins is separated from the mixture while a speed of the screen separator and a speed of the mixture at the interface with the screen separator remains about equal and reducing or eliminating shear forces at the interface between the screen separator and the fish flesh. Thus, washed fish flesh fish flesh with an increase in a percent of myofibrillar protein retained in the fish flesh is produced.

  • Patent number: 8845886
    Abstract: This invention relates to a process for separating a hydrocarbon stream via a filtration process to produce an upgraded permeate stream with decreased Conradson Carbon Residue (“CCR”) content. The invention involves the modification of a porous ceramic filter by functionalizing the surface of the ceramic filter with an multi-ring aromatic-diimide polymer. Preferably, the multi-ring aromatic-diimide polymer is comprised of a multi-ring aromatic monomer component. The functionalized filters of the present invention can be used in a process to selectively separate components of a hydrocarbon stream to produce an improved permeate (or “filtrate”) product stream with a lower CCR content and improved processing capabilities.

  • Patent number: 8535531
    Abstract: A water treatment system may generally comprise a generally cylindrical halogenated resin bed comprising an empty bed contact time greater than 1 second, an aspect ratio less than 0.8, and a fluid velocity less than 0.5 cm/s, wherein the aspect ratio is the ratio of the length of the halogenated resin bed to the diameter of the halogenated resin bed; and wherein the fluid velocity is the quotient of the volumetric flow rate of the water treatment system and the cross-sectional area of the halogenated resin bed; and wherein the halogenated resin bed improves the removal of contaminates relative to a corresponding water treatment system having an aspect ratio greater than 0.8.

  • Patent number: 8524080
    Abstract: An apparatus for removing cyanotoxins and excess ions from contaminated water. Contaminated water passes from a storage tank (200), through a sand filter (210), through a reaction chamber (230), and finally through a carbon filter (270). The sand filter removes particulates and some bacteria. Treatment of the water in the reaction chamber first destroys cyanotoxins, algae, and bacteria through the use of high voltage shocks applied between two groups of electrodes (285, 285?), then the voltage on the electrodes is lowered and electrolysis is used to sequester free ions in the water in the region near the electrodes. Partially treated water is removed from the upper portion of the reaction chamber and passed through a carbon filter (270) to remove radiation, and to improve taste and smell. After passage through the carbon filter, the water is potable. The water remaining in the reaction chamber is discarded into a reservoir (265).

  • Publication number: 20130206676
    Abstract: The present invention relates to a measuring device having a pressure sensor, with the pressure sensor having a measuring cell designed to detect a pressure. It is provided that the measuring cell of the pressure sensor is arranged in or adjacent to a protective cell filled with a measuring fluid that can be coupled to a fluid to be measured via at least one separating membrane. It is furthermore provided that a damping device is arranged in the protective cell between the separating membrane and the measuring cell, said damping device including a restrictor and a downstream volume expansion means that provides an increased volume between the restrictor and the measuring cell in the event of a pressure increase in the measuring fluid.

  • Patent number: 8443985
    Abstract: A deposition of bubbles or foams to an inner wall of a liquid supplying member is prevented, thereby improving ejecting performance of the bubbles or foams. In the liquid supplying member which forms a flow path for supplying a liquid to a liquid discharging apparatus, the inner wall surface has a concave/convex shape in which a mountain portion and a valley portion are repeated at a predetermined spatial frequency. Assuming that an opening diameter of a filter provided for the liquid discharging apparatus is equal to R (?m), one period f (?m)of the spatial frequency lies within a range from R or more to ?{square root over (2)}·R or less and a maximum height Ry (?m) of the mountain portion is equal to ?{square root over (2)}·R/2 or more.
