  • Patent number: 9452453
    Abstract: A system and method for uniformly applying a wetting agent to a treatment surface. The method involves providing a reservoir for the wetting agent that is maintained at ambient pressure. The wetting agent is pumped away from the reservoir by an electrically driven suction pump to a nebulizing nozzle. A spray of droplets of the pumped wetting agent is created by passing through the nebulizing nozzle. The spray of droplets is uniformly applied to the treatment surface. In one embodiment, the wetting agent is a formwork fluid and the treatment surface is a concrete formwork. In another embodiment, the wetting agent is an asbestos dampener and the treatment surface is an asbestos containing material.

  • Patent number: 5710434
    Abstract: The invention is directed to a composition of matter useful as a paper impregnant, to the method of its use, and to the products produced by the method. Poly (diphenylmethane diisocyanate) or PMDI has been used in the past as a paper impregnant with or without propylene carbonate as a diluent. These products have generally required pressing under high pressures and at elevated temperatures. It has now been found that triacetin and/or triethyl citrate in usages up to about 20% of PMDI give superior performance in impregnated products. The modified PMDI will cure at essentially ambient conditions in times as short as 1-2 days to insoluble polyureas with low residual amounts of isocyanates and reaction byproducts such as 4,4'-diaminodiphenylmethane. The treated papers can be used in applications of which skins for sandwich panels and high strength corrugated board would be exemplary.

  • Patent number: 5558472
    Abstract: A method for transporting particles such as polyolefin particles from a first container to a second container. The particles are transported from the first container to the second container through a transportation pipe by means of a pressure difference between the first container and the second container. A valve is provided in the transportation pipe near the second container, and the valve is closed and opened to transmit particles intermittently. Cleaning gas is fed into the transportation pipe at a position on the inlet side near the valve. The cleaning gas is gas consisting essentially of olefin monomer. The cleaning gas is fed into the transportation pipe while the valve of the transportation pipe is closed, and the particles remaining in the transportation pipe are sent back to the first container thereby to clean the transportation pipe. Therefore, the inside of the transportation pipe is kept clean all the time.

  • Patent number: 4050943
    Abstract: There is disclosed a method of and composition for making exposed aggregate concrete castings which comprises applying a film to the face of the mold or form, comprising a chelating agent to prevent the setting of the cement to a pre-determined depth at the face, whereby the ultimate appearance of the casting is decorative and the removal of the matrix to produce such appearance is effected by water, the penetration of the compound into the face depending on the selection and concentration of various ingredients. A single film only is applied to the form, and the material from which the film is formed includes cellulose ethers, aliphatic hydroxy acid or salts thereof, and one or a mixture of the lower aliphatic alcohols selected from the group methanol, ethanol or iso-proponol or a ketone. A plasticizer is often used as well as an identifying dye.

  • Patent number: 4006030
    Abstract: The surface of an inorganic substrate comprising cement, concrete, gypsum or mixtures thereof is treated with a silicate solution or a silica sol comprising a monovalent alkali metal containing component, an ammonium containing component and a silica containing component at a molar ratio of 1:1.about. 10:4.about.5000 corresponding to M.sub.2 O:[R.sub.1 R.sub.2 R.sub.3 R.sub.4 N].sub.2 O: SiO.sub.2 wherein M is Li, K or Na; and R.sub.1, R.sub.2, R.sub.3 and R.sub.4 each represent a hydrocarbon group or an alkanol group. The underlying inorganic substrate thus has a modified surface layer thereon having a thickness of less than 50 mm, which functions to protect and prevent deterioration of the underlying surface of said inorganic substrate.
