  • Patent number: 11338258
    Abstract: Devices for treating aqueous pulps of organic materials usable in the food industry, perfumes, in the production of technical and food alcohol, in the processing of organic waste, etc., are provided. A rotary-pulsation device contains a drive, a stator, and a rotor installed in a housing. A vibration sensor is installed on an outer side of the stator to diagnose conditions of the working bodies and for continuous correction the shaft rotation speed. Reliability of the rotary-pulsation device and processing efficiency are increased by reducing manual cleaning related stops and breakage-related failures. The scope of usage is expanded because automatic processing of water pulps containing large-sized and extended fragments becomes possible; the treated pulp is saturated with small gas bubbles; and automation capabilities may be expanded when integrating the device into substrate processing systems.

  • Patent number: 8215823
    Abstract: A cement mixing method for mixing cement used in cementing oil wells casing and the mixer used in that method. The mixer employs a straight bulk cement inlet, five annular recirculation jets and five annular water jet orifices located downstream of the recirculation jets so that all of the jets discharge at an angle towards the mixing chamber and the discharge from the water jet orifices intersects with the flow from the recirculation jets. This five jet, intersecting flow design allows for more thorough wetting of the cement powder with a smaller, lighter, less expensive and more durable mixer that is less inclined to foul and easier to clean.

The flow-rates of the individual components are regulated in quantitatively proportional manner with reference to the flow-rate of a first component. The resulting regulated flow-rates are introduced into a receiving container, either directly or after individual flow-rates have been completely or partially conducted together. The process and the device are especially suitable for the on-site production of mixtures of substances that cannot be transported or that can only be transported in elaborate manner, such as relatively highly concentrated solutions of peroxycarboxylic acid.

  • Patent number: 6290384
    Abstract: A method and apparatus for producing a liquid mixture in which mixture components are mixed to produce a product stream having a predetermined connection of a specified component. This mixing occurs within a fluidic network designed such that the components mix in inlet branches to form a first intermediate mixture having a lower concentration than that desired in the product stream. The specified component is metered into the intermediate product stream to produce a second intermediate product stream that is blended to produce a third intermediate product stream. The concentration of the specified component within the third intermediate product stream is measured and the metering pump is appropriately adjusted. The third intermediate product stream then passes through a recycle loop in which recycled product is mixed with an intermediate product stream to produce a liquid mixture stream that is divided into the recycle stream and a product stream.

  • Patent number: 6261486
    Abstract: For the production of polyurethane moldings by the shot process from isocyanate and polyol components, the production is improved in that, in addition to the conditioning already known for the line system, at least one of the commercially available but modified metering pumps is also conditioned in that some of the reaction component made available flows in circulation through the intermediate space between the enclosed metering component and housing of the pump.
