  • Patent number: 10081125
    Abstract: Method and apparatus for removing bubbles from a molten substrate. The molten substrate from a furnace passes through a downtube to reach additional manufacturing tools, such as an extrusion bushing. One or more ultrasonic sensors are arranged along the downtube. The ultrasonic sensor(s) transmit ultrasonic energy into the molten substrate and measure a characteristic of the ultrasonic energy, such as a propagation time for the ultrasonic energy to be reflected back to the ultrasonic sensor(s). A bubble is detected when a change in the characteristic of the ultrasonic energy is detected. When a bubble is detected, flow through the downtube is diverted to a duct to remove a slug of molten substrate that includes the bubble.

An acoustic element is coupled to a substrate which is located within and at the bottom of the lower chamber and which resonates in response to the acoustic generating element and generates a standing wave through the two fluid phases and the filter to agitate the sample. Simultaneously, a cyclic process of vacuum draw, causes movement of the sample downwards through the filter. Vacuum pressure, fluid flow rate and frequency of vibration are controlled from a remote unit housing appropriate pumps and valves.

An arrangement of the spouting part (20) and the particle collecting face (31) with respect to each other is adapted to generate, during operation of the device (1), a rotating flow pattern in the fluid that is present in the chamber (10) under the influence of the flow of the fluid to be filtered, whereby particles can be blown away from the particle collecting face (31).

    Abstract: A system for filtering and sampling, preferably but not exclusively, of oil drilling mud for the purpose of analyzing the gaseous component contained in debris produced by well-drilling and transported by said mud. The system is provided with a filtering surface developed in three dimensions and with various methods for cleaning the filtering surface with which any contact is avoided between the cleaner and the filtering surface. This prevents further and excessive incrustations of debris on the meshes of the filter and avoids an undesirable passage of air in the aspiration pipe when the filter is partially immersed.

  • Patent number: 8324377
    Abstract: A water-soluble cellulose ether is separated from its suspension by passing a suspension of water-soluble cellulose ether particles in water through a filter of perforated metallic or ceramic filter medium under pressure, removing the filter cake of water-soluble cellulose ether from the filter medium, and cleaning the filter medium with steam, compressed air or water under pressure. The invention enables to separate a water-soluble cellulose ether, especially having a high dissolution temperature, avoids the filter from being clogged, and extends the operative time of the filter.

  • Publication number: 20120160783
    Abstract: The water filtration device and method introduce raw water into a filtration barrel where the water is purified by filter elements inside the filtration barrel. A main frame is set up in the filtration barrel and a driving motor is mounted on the main frame. The driving motor engages a holding rack inside the main frame to spin at high speed. Filter elements are stacked and interleaved on the holding rack. When the filter elements require cleaning to remove the attached contaminants from the raw water, filter elements are rotated at high speed along with the holding rack so that the contaminants are thrown off by the centrifugal force. When the filter elements are cleaned, the high-speed rotation of the filter elements could be stopped and the filtration process could be continued or terminated.
