  • Patent number: 11224989
    Abstract: There is described a method for determining a volume of fresh concrete being discharged from a drum during a discharge, the drum being rotatable and having inwardly protruding blades mounted inside the drum which, when the drum is rotated in an unloading direction, force the fresh concrete towards a discharge outlet of the drum. The method generally has discharging a volume of the fresh concrete from the drum by rotating the drum in the unloading direction for a given number of discharge rotations; obtaining discharge flow rate variation data indicative of a discharge flow rate varying as function of discharge rotations; and determining a discharged volume value indicative of the volume of fresh concrete being discharged from the drum of the mixer truck during said discharge based on the given number of discharge rotations and on the discharge flow rate variation data.

  • Patent number: 11221028
    Abstract: Disclosed cyclonic flow-inducing pumps overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such cyclonic flow-inducing pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated adverse considerations such as slugging.

  • Patent number: 11185797
    Abstract: An agitation/defoaming device is provided, which can independently control revolving and rotational motion and can change a rotational direction relative to a revolving direction without a two-system rotary drive. The apparatus includes a rotary driving source, a braking device for rotary motions; first and second rotors revolved around revolving shaft, and first and second rotational bodies and container holders pivotally supported by the first rotor. A braking force is applied to the second rotor revolving along with the first rotor, generating a rotational motion, which is transmitted to either the first or second rotational body according to the revolving direction of the first rotor. The rotational motion is then transmitted from the first or second rotational body to the container holder through the first rotational body, thereby transmitting to the object the rotational motion according to the revolving direction while revolving the object.

  • Patent number: 11130714
    Abstract: Disclosed are dosing methods for mitigating the deleterious effect of clays, which are born or conveyed by sand aggregates, crushed rock, gravel, and other aggregates used in the manufacture of concrete, upon the dosage efficiency of cement dispersants added into concrete. Instead of introducing the entire clay mitigation agent (CMA) into the aggregate material before or during batching in the cement batch plant in a singular, upfront dose, the present invention comprises administering CMA doses on at least two instances in a rotatable truck-mounted mixer drum, wherein at least 21%-100% of the total CMA added into the concrete is added after initial batching of water, cement binder, and clay-bearing aggregates in the rotatable truck-mounted mixer drum during the transit portion of the delivery between initial batching at the cement batch plant and the pour event at the job site.
