Abstract:
A system for delivering and applying a flowable mixture to an article (311-313) is disclosed. The system includes a mixture delivery system (200) and a skinning system (300). The mixture delivery system (200) includes a mixer (220) configured to mix a dry material and a fluid to produce the flowable mixture, and a pump (235) configured to pump the flowable mixture to a delivery line. The skinning system (300) receives the flowable mixture from the mixture delivery system (200) through the delivery line. The skinning system (300) includes a skinning pipe (310) configured to apply the flowable mixture to the article (311-313) and a manifold (305) that supports the skinning pipe (310). The skinning system (300) also includes an article feeding mechanism (315) configured to push the article (311-313) into the skinning pipe (310). The skinning system (300) includes a transfer system (320) configured to hold the article (311-313) and move the article (311-313) out of the skinning pipe (310).

Abstract:
There is disclosed a system for depositing building materials comprising a motor vehicle, a container comprising a material depositing system and at least one device for removing the container from the motor vehicle. The device can comprise one or more outriggers which are adapted to remove the container from the motor vehicle and which can be used to deposit the container on a job site. There is also disclosed a process as well, which includes at least one of the following steps providing a base slab floor; bull floating the base slab floor, inspecting the base slab floor for debris, utilizing a measuring device to survey height dimensions, applying an adhesive intermediary, inserting plastic pins with respect to survey measured points, mixing a self leveling compound, pumping the mixed compound through a conveying system, and smoothing the mixed compound to create a uniform surface and floor which is cured.
Abstract:
A system for managing a concrete delivery vehicle having a mixing drum 14 and hydraulic drive 16 for rotating the mixing drum, including a rotational sensor 20 configured to sense a rotational speed of the mixing drum, a hydraulic sensor 22 coupled to the hydraulic drive and configured to sense a hydraulic pressure required to turn the mixing drum, a temperature sensor for sensing temperature of the drum, and a communications port 26 configured to communicate a slump calculation to a status system 28 commonly used in the concrete industry, wherein the sensing of the rotational speed of the mixing drum is used to qualify a calculation of current slump based on the hydraulic pressure required to turn the mixing drum. Temperature readings are further used to qualify or evaluate a load. Also, water purge connections facilitate cold weather operation.
Abstract:
A system for producing ready-to-use mixtures of lightweight construction materials is provided. The system includes a subsystem for mixing and controlling the dry construction materials, a subsystem for mixing and controlling the additive materials, a main mixer which produces the ready-to-use mixture of lightweight construction material and a computerized control unit which controls the manufacturing process and thereby producing a ready-to-use mixture of lightweight construction material which is substantially uniform and has a controlled specific gravity. The present invention further provides an automated line of production for manufacturing ready-to-ship porous lightweight brick walls, controlled by the computerized control unit
Abstract:
A vibrating flexible smoothing sheet or shroud disposed transversely of a direction of travel of a formed fiber panel including gypsum-cementitious slurry and embedded chopped fibers. The sheet is used to smooth the surface of the panel as it exits a fiber embedment station of a structural cementitious panel production line to remove grooves and other non-uniform surface imperfections to reduce the need for costly finishing after the panels are cured and cut to size. The flexible sheet is designed to float over the surface of the formed panel without tearing or otherwise damaging the surface of the heavily fiber reinforced surface layers of the panel. The vibrating sheet is pivotally mounted on the side dams of the web production line so it can float over the panel surface during use, but be raised off the line when not in use.
Abstract:
A process for making construction material may include mixing predetermined portions of two or more components of cementitious materials without ingredients that would allow the mixture to cure, and separating the un-curable mixture of the two or more components into a plurality of pellets, each having substantially the predetermined portions of the two or more components. An extrusion system may include a transport line configured to transport the dry pellets in a gaseous transport stream.
Abstract:
The present invention provides a method of making quality, homogenous mixtures such as concrete without premixing the separate ingredients. In the example of concrete, the ingredients of cement, gravel, sand and water are metered and delivered to the use point separately using separate delivery means such as separate pneumatic hoses. The flow or delivery rate of each ingredient is measured and separately controlled, and the outputs of the individual delivery means meet at the common use point simultaneously where the concrete is to be laid down. The ratio of the ingredients may be adjusted to tailor the mix for particular applications. The ingredients meet and mix for the first time at the use point, and no premixing is performed.
Abstract:
Compositions and methods are provided for a system in which liquid carbon dioxide, or a mixture of liquid and gaseous carbon dioxide, is converted to solid carbon dioxide by exiting an orifice at a sufficient pressure drop, e.g., for delivery of carbon dioxide to a concrete mixture in a mixer.
