  • Patent number: 9714741
    Abstract: A chemical/additive injection controller, system and method (i.e., utilities) are provided that control when an injection pump turns on and off in order to inject a predetermined volume of additives into a hydrocarbon production conduit over a predetermined number of cycles per day. The controller determines when to activate and deactivate (i.e., turn on and turn off) an injection pump to provide a desired total additive injection volume over an injection period (e.g. 24 hours). More specifically, the utilities incorporate a flow meter that monitors the actual amount of additive that is injected during a pump cycle. Once an injected volume meets or exceeds a target injection volume the pump is deactivated. The flow meter continues to monitor the injection volume including amounts injected after power to the pump is deactivated to provide an accurate measure of the total injection. Subsequent injections are varied based on the actual measured volume of one or more previous injections.

  • Patent number: 8951343
    Abstract: Ultra-high-performance cementitious materials are made using suitably functionalized and relatively low-cost carbon nanofibers and graphite platelets. Polyelectrolytes and surfactants are physisorbed upon these graphite nanomaterials in water, and dispersion of nanomaterials in water is achieved by stirring. Stable and well-dispersed suspensions of nanomaterials in water are realized without using energy-intensive and costly methods, and also without the use of materials which could hinder the hydration and strength development of ultra-high-performance cementitious materials. The water incorporating dispersed nanomaterials is then mixed with the cementitious matrix and, optionally, microfibers, and cured following standard concrete mixing and curing practices. The resulting cementitious materials incorporating graphite nanomaterials and optionally microfibers offer a desired balance of strength, toughness, abrasion resistance, moisture barrier attributes, durability and fire resistance.

  • Patent number: 8545619
    Abstract: Synthetic fibers, such as polypropylene fibers, are mixed in a shrinkage compensating concrete to provide restraint in lieu of conventional steel reinforcement used in a shrinkage compensating concrete. While the synthetic fibers have a low elastic modulus and low strength, they act to restrain expansion of the concrete in the same way that conventional steel rebar does. In addition, only a small amount of the synthetic fibers are needed to restrain the expansion. As a result, shrinkage compensating concrete can be used in more varied applications, and can be provided more quickly, easily and inexpensively. Construction time requirements and expenses of concrete structures are correspondingly reduced.

  • Patent number: 8303707
    Abstract: Synthetic fibers, such as polypropylene fibers, are mixed in a shrinkage compensating concrete to provide restraint in lieu of conventional steel reinforcement used in a shrinkage compensating concrete. While the synthetic fibers have a low elastic modulus and low strength, they act to restrain expansion of the concrete in the same way that conventional steel rebar does. In addition, only a small amount of the synthetic fibers are needed to restrain the expansion. As a result, shrinkage compensating concrete can be used in more varied applications, and can be provided more quickly, easily and inexpensively. Construction time requirements and expenses of concrete structures are correspondingly reduced.

  • Publication number: 20120261861
    Abstract: A metal fiber reinforced composition and its method of fabrication. Metal fibers are created by broaching or shaving metal wool from stock material. The wool is straightened and cut into short lengths. Each of the metal fibers has an average maximum diameter of between 0.005 millimeters and 0.2 millimeters, and a cut length no greater than two-hundred times the average maximum diameter. A volume of a curable composition is provided. The metal fibers are mixed into the curable composition to create a fiber reinforced composition. The fiber reinforced composition is then formed into a selected shape, such as a construction element. The selected shape is then cured. Since the metal fibers are dispersed uniformly throughout the selected shape, curing or re-heating of the selected shape can be facilitated using an induction coil that heats the various metal fibers within the selected shape.

    Abstract: A refractory includes a cement, a binder and a matrix. The matrix comprises both stainless steel fibers and organic fibers. The refractory can be easily cast, without additional steel reinforcement, into large fire wall 16 panels 10 capable of meeting the requirements of testing conducted in accordance with ASTM E-119, Standard Test Methods for Fire Tests of Building Construction and Materials in support of IEEE Std. 979-1994, Guide for Substation Fire Protection. The fire wall 16 assembly withstood the fire endurance test without passage of flame and gases hot enough to ignite cotton waste during a four-hour fire exposure. The assembly also withstood a 45 psi water stream for five minutes immediately following the four-hour fire exposure period. This is a stringent mechanical requirement, as all fire walls 16 must maintain their integrity before, during and after a fire, per the Universal Building Code's definition of a true fire wall 16.

  • Patent number: 8277556
    Abstract: Lightweight cementitious foams of the invention have excellent dynamic and dimensional stability due to use of foaming system comprising polycarboxylate surfactant foam generating agent, foam stabilizer (e.g., PVOH), and shrinkage reducing admixture to inhibit plastic shrinkage and micro-cracking of cement. The foaming system can be used in conventional cement mortars or concretes as well as with exemplary cementitious slurry systems of the invention, which include an expansive agent, a cross-linking agent for the foam stabilizer. Microfibers can be used in the foam, slurry, or both, to prevent micro-cracking. Cementitious foams can be made without use of autoclave or lightweight aggregates to achieve enhanced compressive strength and thermal insulation properties that compare favorably with conventional foams and insulation materials at comparable densities.
