  • Patent number: 10352043
    Abstract: Method of forming a concrete slab to reduce or eliminate control joints includes preparing a substantially flat base, overlaying one or more barriers on top of the base, placing a concrete mixture on top of the barrier(s) and base to form a concrete slab, and allowing the concrete to cure without forming control joints. The base is prepared with a flatness of about ±¼ inch over 10 feet. A side edge is prepared along a periphery of the concrete slab by extending a vapor barrier from a bottom surface of the slab up the side edge toward a top surface of the slab and covering the side edge. A plurality of post-tensioning cables are positioned to extend through the slab and configured to compress and assist in controlling accelerated displacement of the concrete slab during curing and shrinkage. The concrete slab is formed of an evenly gradated and low slump concrete having high fiber content, minimized cement content, and maximized size of large aggregate.

  • Patent number: 6706401
    Abstract: This invention is a rapid low-cost technique for manufacturing thick high-performance carbon and ceramic composites in the form of uniformly densified near-net shaped structures. This is accomplished by impregnating composite preforms with low-viscosity wetting monomers which undergo polymerization followed by pyrolysis reactions in the preform ultimately creating ceramic and/or carbon matrices. Since the monomers possess low-molecular-weight they have low viscosities. Thus, if they wet the fiber and partially-densified preform they can easily impregnate even the smallest pores. Once inside the preforms, polymerization of the monomers is then initiated, resulting in a liquid matrix-precursor of the high molecular weight needed to produce a superior matrix (upon pyrolysis) with high efficiency.

  • Patent number: 6231994
    Abstract: A moisture containing wooden core substantially fully encapsulated within a formed in situ substantially non-wetting water impervious thermoplastic envelope. An effective amount of an insect and fungi controlling water soluble reagent is provided within the envelope. Preferably, there is sufficient moisture in the envelope so that the reagent will migrate substantially throughout the wooden core. The encapsulated workpiece is preferably formed by dipping or spraying the moist wood core with the aqueous reagent, and encapsulating the resultant treated core before it dries out so that the core remains moist throughout its expected life span. Green freshly harvested wood can be treated, coated, and used in direct competition with dried wood, without risk of its warping, splitting and checking during its expected useful life. Boron containing compounds are preferably used as the infection controlling reagents.

  • Patent number: 6197137
    Abstract: The present invention provides a method of preventing adhesion of aquatic organisms on structures in the water such as ships. In the method, the underwater part of a structure in the water is covered up with the sheet. The sheet is made of a polyolefin and less than 1 mm thick, and has apertures each of which has a surface area of 1 to 60 mm2, the surface area in total of the apertures occupying 20 to 80% of the entire surface area of the sheet. The sheet has a tensile strength of 15 to 37% as measured under JIS L1096A and a tear strength of 3 to 9 kg as measured under JIS L1096A-1.

  • Patent number: 6180162
    Abstract: An excellent antibacterial property is afforded upon a metallic article by simple steps of coating a dispersion liquid or a solution of fine particles made of an antibacterial ingredient on the surface of the metallic article and pressing the resulting coated surface of the metallic article under a non-heated condition or rubbing the resulting coated surface of the metallic article. In addition, a conventional rolling step or the like can be used itself without any change in the above treatment, which is economically extremely advantageous. Furthermore, since the antibacterial metallic article according to the present invention is obtained under the non-heated condition, the antibacterial ingredient is not deteriorated. Further, since the antibacterial property is not lost through some abrasion, excellent antibacterial property can be exhibited over an extended time period. Further, there is no fear that surface characteristics of the metallic article, for example, a tone of color will change.

  • Patent number: 6132877
    Abstract: A carbon--carbon composite clutch friction material for use with a wet lubricant under severe operating conditions is disclosed, the material comprising a woven carbon fabric mesh (suitably a satin weave mesh) infiltrated with pyrolytic carbon to an unusually high density in the range of at least 1.3 g/cc to about 1.5 g/cc. By infiltrating the woven carbon fabric with carbon to such high density, a wear-resistant friction material is provided that still retains enough surface texture for lubricant transport.

  • Patent number: 6040251
    Abstract: The present invention includes novel barrier webs that have certain desirable physical qualities such as water resistance, increased durability, improved barrier qualities and the like. The present invention further comprises a barrier web comprising a web that has been treated with a curable shear thinned thixotropic polymer composition, the fabric being adapted to be substantially impermeable to liquids, permeable to gases and impermeable to microorganisms. The barrier webs of the present invention are either impermeable to all microorganisms or are impermeable to microorganisms of certain sizes. The present invention also includes fabrics that are capable of either selective binding certain microorganisms, particles or molecules depending upon what binding partners are incorporated into the polymer before application to the fabric.

  • Patent number: 6030697
    Abstract: A plurality of garments are impregnated with an effective amount of permethrin to provide protection against insects by use of a combination of an industrial washing machine and holding tank containing permethrin solution of predetermined strength. The permethrin solution is pumped through the washing machine during washing and returned to the holding tank after the wash cycle is completed. The process is repeated as often as needed. Extracted liquid resulting from a spin cycle to dry the garments after washing may also be circulated to the holding tank and ultimately recirculated.

  • Patent number: 5948474
    Abstract: A method for impregnating rock or landscaping material with bio-active and/or colored fluid. To impregnate the rock or landscaping material with bio-active chemical, the rock or landscaping material is heated to dehydrate it, and cooled to an ambient temperature in a dehumidified chamber, and then placed in a pressurizable container which is filled with bio-active chemical. The pressurizable container is placed under pressure for a sufficient time that the bio-active fluid is forced into the interstices of the rock or landscaping material. When the rock or landscaping material is removed from the pressurizable container, it has been impregnated with bio-active chemical and gradually emits the bio-active chemical. The rock or landscaping material may be cleaned using water or a solvent. The bio-active chemical used can be a herbicide, pesticide, plant or insect growth hormones, repellents of cats, dogs, mice, or other pests, or fertilizers.

  • Patent number: 5869172
    Abstract: Improved processes are provided for treating a porous substrate (especially a fabric) to produce novel internally coated porous materials. During treatment, a curable thixotropic material and one or modifying materials are applied to the porous substrate as an impregnant. The treatment imparts specific properties to the end product material. Selection of the modifier material is based on the particular end use application. Sufficient energy is directed to the impregnant and porous substrate to cause the impregnant to flow into the porous substrate and force the modifier to specific positions within the substrate.
