| 20120024046 | MEASURING DEVICE FOR MEASURING CONSISTENCY OF CEMENT SLURRY FOR A CONSISTOMETER - This present invention relates to a measuring device for measuring consistency of cement slurry for a consistometer. The measuring device comprises a high-pressure vessel, a slurry cup and a magnetic driver, wherein the slurry cup is rotatably mounted inside the high-pressure vessel by the magnetic driver, stir blades are hanged in the slurry cup, and the magnetic driver is driven by a driving motor which is located outside the high-pressure vessel and is further provided with a tension sensor. The invention cancels the conventional mode for measuring consistency by a potentiometer, uses the tension sensor to measure the torque transferred from the driving motor to the magnetic driver, i.e. the cutting torque created by the stir blades on cement slurries within the slurry cup, thereby measuring the consistency of cement slurry. | 02-02-2012 |

| 20150355160 | CONCRETE MIXTURE MEASUREMENT SENSOR, SYSTEM AND METHOD - A sensor measures slump and rheological characteristics of the concrete and is connected to a system that adjusts the slump by monitoring the sensor within the interior surface of a concrete mixer and controlling liquid additions. Data is analyzed by a computer processing unit to determine the slump and rheological characteristics of the concrete, liquid required to meet the slump requirements. The measurement done by the sensor is more accurate then the existing methods because it brings into consideration the effect of the helix inside the mixer on the movement of the concrete mixture inside the mixer. Furthermore, this method also allows the operation of the sensor in “real” life situations where the rotation speed of the mixer can't be maintained at a fixed value. The fact that the sensor rotates with the drum and that the concrete mixture is pushed to the bottom of the mixing drum guaranties that all the concrete is “sampled” by comparing results collected from each revolution of the mixing drum. | 12-10-2015 |
