| 20150298351 | METHODS AND SYSTEMS USING CONCRETE MIX TEMPERATURE MEASUREMENT - The temperature of concrete can be monitored by a temperature probe. Typically, large volumes of concrete such as are typically carried in mixer trucks or mixed in industrial concrete production drums have a relatively stable, or slowly varying temperature, given the high thermal capacity of concrete. A sudden change in temperature can thus be attributed to an external event. A sudden addition of even a relatively small amount of water for instance, which has an even higher thermal capacity, can produce a notable sudden change in temperature. Examples where the detection of the addition of water can be particularly useful in the production and/or transport of concrete are provided herein. Moreover, if the temperature of the added water is known, and the quantity of concrete is also known, the sudden difference in temperature can be correlated to a volume of added water. | 10-22-2015 |

| 20160107132 | Portable Cement Mixing Apparatus with Precision Controls - A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. As the desired weight of an ingredient is added to the mixing chamber, the computer slows and then stops the inflow of the current ingredient being loaded via broadly variable control of the loading of the ingredients. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. Further, a damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention. The combination of highly accurate control over the input of materials added to the mixing chamber as well as the maintenance of permanent records concerning each batch of cementitious slum made allows the production of precision batches of final products to meet exacting specifications needed in both ordinary projects and highly specialized projects requiring cementitious products. Data recorded during production operations further allow accurate identification of manpower needs of projects and allow owners/operators at job sites to record, control, predict and manage production costs and manpower needs. All recorded data is transmitted to an offsite location for management to use as needed for quality and management control and can be transmitted at any time or hatch interval desired by management. | 04-21-2016 |
