  • Patent number: 10288473
    Abstract: A suspended hopper apparatus is adapted to dispense a flowable product. Three supports, a vessel, and a valve mechanism are provided. One of the three supports is a scale-support, and the other two supports are pivot-supports. A scale-support is a support which comprises a scale, wherein the scale is of a type which resists translation in only one direction, and does not resist translation in any lateral direction and wherein the direction is vertically-upward, and resists by providing upward support with respect to the vessel. The pivot-supports are supports which comprise pivots, the pivots resisting translation and are arranged to resist forces that are applied to the apparatus in the lateral direction. The pivots define a common axis of rotation, the axis extends in a horizontal direction and the pivots do not resist rotation about their axis. The vessel has centerline that is offset laterally from its axis and the product has a product centerline that is offset laterally from its axis.

  • Patent number: 10119853
    Abstract: An apparatus or method for weighing and/or measuring the flow rate of quantity of a particulate flowing out of a hopper wherein the hopper is isolated from the other components of the apparatus. The apparatus and method are adapted to generate a decoupling point boundary that demarcates the total amount of particulate in the hopper into portions that are not fully supported and portions that are fully supported by the hopper. The particulate is in continuous contact with itself from the inlet to the outlet, with the particulate contained between the isolated hopper and the rest of the components of the system by a flexible coupling or some other method of containment. The invention has the advantages of higher accuracy, decreased cost and complexity, and greater reliability than other solid particulate weighing systems of the prior art, particularly when dealing with low density particulates.

  • Publication number: 20140269144
    Abstract: A slurry mixing system calculates a density of a slurry using measured pressure differential and bulk velocity of the slurry. Slurry from mixing of dry blend and mix fluid enters a one or more tanks having agitators. A pump then pumps the slurry from the tank(s) to the well, and a portion of the slurry is recirculating back to a mixer. From the recirculated path, a direct slurry weight sensor measures a pressure differential of the slurry between two vertical measurement points of a known volume, and the sensor measures a velocity of the recirculated slurry. Based on these measures, the controller calculates a density of the slurry, monitors a ratio of the dry blend and the mix fluid, and adjusts the ratio based on the calculated density of the slurry if there is a discrepancy.

    Abstract: The invention relates to a method for adjusting concrete rheology requiring only that load size and target rheology value be selected initially rather than requiring inputs into and consultation of a lookup table of parameters such as water and hydration levels, mix components, temperature, humidity, aggregate components, and others. Dosage of particular rheology-modifying agent or combination of rheology-modifying agents is calculated based on a percentage of a nominal dose calculated with reference to a nominal dose response (“NDR”) curve or profile. The NDR profile is based on a correlation between a rheology value (e.g., slump, slump flow, yield stress) and the rheology-modifying agent(s) dose required to change rheology value by one unit (e.g., slump change from 2 to 3 inches) such that exemplary methods can employ corrective dosing based on the NDR and the measured deviation by the system.

    Abstract: An improved volumetric concrete mixing system and method of the present invention utilizes load cells for measuring weight loss from the aggregate and cement bins. Load cells may also be used for measuring weight loss from the water tank. The load cells provide input data corresponding to the weight loss of each container to a controller which automatically adjusts the delivery of ingredients to a mixing boot so as to achieve a desired concrete mix ratio.

  • Patent number: 7561943
    Abstract: Methods of controlling a volumetric ratio of a material to total materials in a mixing vessel are provided. In various embodiments, the methods may comprise: estimating the volumetric ratio of the material to the total materials in the mixing vessel and an output flowrate of the material from the mixing vessel using a volumetric ratio observer; dynamically recomputing the commanded input flowrate of the material based on outputs of the volumetric ratio observer using a flow regulator; and adjusting an input valve of the material based on the commanded input flowrate of the material using a flow modulator. The mixing vessel may include a first mixing vessel partially separated from a second mixing vessel. In this case, a height of the total materials in the second mixing vessel may be estimated using a height observer.

  • Publication number: 20090156725
    Abstract: The present invention provides a manufactured aggregate material that converts waste materials and/or recyclable materials into construction material. By mixing waste materials with an acid solution and a metal oxide solution, any harmful contaminates in the waste materials are encapsulated and rendered into hard pellets that are suitable for use in conglomerates or composites such as concrete. The manufactured aggregate material may be adjusted for moisture content, density, heat capacity, and other parameters.

  • Patent number: 7464757
    Abstract: A method for continuously batch mixing a homogenized cement slurry is provided that includes providing first and second mix tubs which each perform a process which include: receiving a measured quantity of solid and liquid constituents of a cement mixture; mixing the solid and liquid constituents of the cement mixture into a homogenized cement slurry; and delivering the homogenized cement slurry into a well. In this method, the first and second mix tubs alternate these delivering processes in a synchronized manner such that one of the first and the second mix tubs continually delivering its corresponding homogenized cement slurry to a well pumping system.

  • Publication number: 20080273415
    Abstract: Apparatus and methods produce substantially continuous batches of high-strength concrete. Portland cement, flyash, sand, water, and concrete chemical additives are premixed in a multi-stage process, prior to final mixing with the coarse aggregates. In sequence, the complete mixing process includes: 1) a twin-shaft compulsory mixer to blend the materials, then disposing the mixture into; 2) a horizontal screw conveyor, continuously mixing as the mixture passes through the housing, thereby disposed simultaneously with the coarse aggregates into; and 3) the mixer concrete delivery truck, wherein the concrete is mixed further.

  • Publication number: 20080198685
    Abstract: A method of filling seabed holes involves vessels that locate the holes with sonar and one of which has onboard capabilities for storage of a solid and mixing it with liquid to create a pumpable slurry. The slurry is delivered through a coiled line that is fed out overboard and the end of the line is held in position by maintaining the vessel at the desired location during slurry pumping. The hose end can be held fixed or progressively raised during slurry delivery, depending on the starting depth. The hose further has an end feature that counteracts the tendency of the hose to whip from the force created by the pumped slurry exiting the end. The slurry encounters a plate at the hose end with lateral exits preferably equally spaced circumferentially to maintain the hose end in a steady position as the slurry is delivered.

  • Publication number: 20080165612
    Abstract: Methods for controlling the in-feed and discharge rates of materials flowing into and out of a mixing process where one priority is to achieve a target mixture flow rate from the mixing process and another priority can be to achieve a target value for a mixture property. Actuators can be operated to control material in-feed rates, the mixture composition, and discharge rate, and can maintain a hold-up of the mixture in the mixing process. A total flow rate controller provides a control signal to a controller acting on the discharge rate and a controller acting on the in-feed rates. The mixture discharge flow rate can be automatically reduced from its desired target when the commanded rate of at least one of the materials exceeds its available supply rate as inferred from an inability to maintain the targeted value for the mixture property.
