  • Patent number: 5354787
    Abstract: It is an object of the present invention to provide a soil-stabilizing agent with less emission of dust, good reactivity, good behavior at mixing and good dispersibility and a method for soil stabilizing treatment capable of restraining the emission of dust in the procedure of sprinkling and mixing of the soil-stabilizing agent to soil.The soil-stabilizing agent according to the present invention comprises a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin.And the method for soil-stabilizing treatment according to the present invention comprises the following steps; adding a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin to soil, and mixing them under the hydration heat generated by the reaction between the quick lime and/or calcined dolomite with moisture in the soil to form hydrated material.

  • Patent number: 5256285
    Abstract: A filter container includes a sheet having a base with a liquid inlet pipe and a liquid exhaust pipe and a cap that is integrally attached to the base. A disposable unit container is housed inside the sheet, and the disposable unit container contains cartridge filters. The disposable unit container has a liquid inlet port and a liquid outlet port at a bottom portion thereof, these ports being provided with shut-off valves on the inside of the disposable unit container. The shut-off valves are engagable by the inlet and exhaust pipes on the base of the sheet so that the valves are open by engaging the disposable unit container with the base with the sheet, and are closed by removing the unit container from the base. The bottom end cap supports the lower ends of the cartridge filters above the inlet and outlet ports, and defines the inlet and outlet liquid flow paths. Upper end caps are also provided for sealing the upper ends of the cartridge filters.

  • Patent number: 4836917
    Abstract: A solid-liquid separating apparatus for obtaining a liquid component, for example, from a used solid-liquid mixture for reuse of the same, which includes a filtering member having a hollow cylindrical shape made of a hard porous material such as porous ceramics, sintered metal, layered metal net, sintered resin, unwoven cloth, and the like. The hard porous material is provided with continuous air holes and a device is provided for reducing the pressure in the inner hollow space of the filtering member during the rotation thereof. A scraper is provided for scraping a solid component remaining on the filtering surface of the filtering member after the liquid component is sucked into the inner space of the filtering member. The separating apparatus further includes a cutter for effectively removing the solid component and a device which allows reuse of the mixture with solid particles evenly distributed therein.
