Latest Patents
John O De Mars holds two recent patents that showcase his innovative approach. The first patent is for a "Packaging and dispensing system for fluid and semi-fluid cement." This invention aims to improve the efficiency and effectiveness of cement dispensing. The second patent is a "Thermographic method for determining the volume of concrete in a mixing." This method involves contacting the exterior of a concrete mixing drum with a strip of thermal color-sensitive material. By observing the interface on the color-sensitive material, which is produced by the temperature differential between the concrete and the air above, users can determine the level of concrete in the mixer. This information can then be aligned with a graduated volume indicator to yield the concrete volume in the truck, aiding in the determination of the effective amount of additive to be added to the concrete.
