    Abstract: A job site monitoring system includes a tower-mounted scanner that is situated to monitor all or substantially all of a particular construction site. The scanner is configured to provide data to a processor configured to determine the height of fill material deposited at a job site. The processor is adapted to communicate with a remote client who can review the data collected at the job site. The processor may also be configured to compare the live fill height data to predetermined parameters to determine whether an error condition exists. An alert may be issued upon detection of such an error to enable corrective action to be taken before construction continues at the site.

  • Patent number: 8974593
    Abstract: Cement-SCM blends employ particle packing principles to increase particle packing density and reduce interstitial spacing between the cement and SCM particles. Particle packing reduces the amount of water required to obtain a cement paste having a desired flow, lowers the water-cementitious material ratio (w/cm), and increases early and long-term strengths. This may be accomplished by providing a hydraulic cement fraction having a narrow PSD and at least one SCM fraction having a mean particle size that differs from the mean particle size of the narrow PSD cement by a multiple of 3.0 or more to yield a cement-SCM blend having a particle packing density of at least 57.0%.

After the cutting wedge (14) comes in contact with the elastomer (20), the elastomer (20) is first at least partially compressed only by the rake face (32) between the rake face (32) and the floor (22) before the cutting edge (30) cuts through the elastomer (20). Because of the initially planar compression of the elastomer (20) by means of the rake face (32), an elastic evasive movement of the elastomer (20) is avoided, such that it is possible to cut off significantly thinner pieces from the elastomer (20), and thus the specific surface area of the pieces severed from the elastomer (20) can be increased.

    Abstract: Crushing walls arranged in opposed pairs to form a V-shaped crushing chamber each have a bar spring element arranged adjacent the outer surface thereof. Exciters, capable of providing at least 75 hp to the crushing walls, urge the spring members toward and away from each other causing the crushing walls to converge and crush material therebetween.

  • Patent number: 8632818
    Abstract: Compositions containing calcium phosphate and microcrystalline cellulose are useful as excipients in the preparation of solid dosage forms containing active pharmaceutical ingredients, particularly those prepared by processes involving multiple compaction steps. The recompactibility performance of such compositions is improved through the use of calcium phosphate having a relatively small particle size, e.g., a median particle size of not more than about 20 microns or not more than about 10 microns.

  • Patent number: 8632026
    Abstract: A mill for shredding scrap, comprising a shredding chamber able to contain scrap during the shredding and having a shredding unit, an inlet pipe connected to an opening of the shredding chamber, in order to transfer the scrap toward the shredding chamber. The mill comprises first thrust means associated with the inlet pipe, selectively movable between a loading position of the scrap into the inlet pipe and one or more intermediate positions to transfer by means of thrusting the scrap toward the shredding chamber. The mill also comprises second thrust means, disposed in proximity with the inlet of the shredding chamber, selectively movable between an inactive position, in which they do not interfere with the introduction of the scrap into the shredding chamber by the first thrust means, and one or more thrust positions in which they introduce into the shredding chamber the scrap moved by the first thrust means until the scrap is in proximity with the opening.

  • Patent number: 8632819
    Abstract: Coprocessed compositions containing microcrystalline cellulose and calcium carbonate, wherein the weight ratio of microcrystalline cellulose to calcium carbonate is relatively high, are useful as excipients in the preparation of solid dosage forms containing active pharmaceutical ingredients, particularly those prepared by processes involving multiple compaction steps. Such compositions may be obtained, for example, by preparing aqueous slurries or wet masses of microcrystalline cellulose and calcium carbonate and drying such slurries or wet masses to produce particulate products. The coprocessed products exhibit improved recompactibility, as compared to coprocessed products having lower microcrystalline cellulose:calcium carbonate weight ratios or as compared to physical dry blends of the two excipients.

  • Publication number: 20140001294
    Abstract: A stirred mill comprises a container for containing grinding media and a material to be ground. The container has a longitudinal axis, and an agitator arranged in said container along said longitudinal axis. A restrictor plate is arranged in said container, extending across said longitudinal axis, and arranged to be positioned on top of the grinding media. A method of simulating a grinding process of a stirred mill of a first height in a stirred mill of a second height is also disclosed, wherein said second height is less than said first height. Further, a method of grinding material in a stirred mill is disclosed.

  • Publication number: 20130341439
    Abstract: A method for blending food or beverages, preferably using a blender that is compact enough for home use, rugged enough to blend frozen beverages, simple to use and safe. The blender includes an upper housing, with a front housing door, that covers the moving blending machinery. The blender also includes a cupholder receiving area which allows the user to safely insert a frozen beverage cup inside a cupholder for blending. After the start button is pressed, a cupholder lip will be grasped by the clamping jaw of an elevator assembly to lift the cupholder up. As the cupholder is lifted upward, a cover will be pressed over the top opening of the inserted cup to prevent spillage during blending. The elevator assembly will then continue to lift the cupholder upward until the rotating cutter blades of a spindle assembly cut through successive layers of the frozen beverage.

  • Publication number: 20130329179
    Abstract: Methods for preparing ferroelectric nanoparticles, liquid crystal compositions containing the ferroelectric nanoparticles, and electronic devices utilizing the ferroelectric nanoparticles are described. The methods of preparing the ferroelectric nanoparticles may include size-reducing a starting material comprising particles of a bulk intrinsically nonferroelectric glass to form glass nanoparticles having an average size of less than 20 nm, the glass nanoparticles comprising ferroelectric nanoparticles. Exemplary bulk intrinsically nonferroelectric glasses may include borosilicate glasses, tellurite glasses, bismuthate glasses, gallate glasses, and mixtures thereof, for example. The size reduction may be accomplished using ball milling with a solvent combination such as n-heptane and oleic acid. Liquid crystal compositions may include the ferroelectric nanoparticles in combination with a liquid crystal.

  • Publication number: 20130309495
    Abstract: Graphene produced by media ball milling has very small particle size, a relatively high surface area and unique aspect ratios. It is uniquely suited to make nano-composites or coating by coating or admixing other particles. Metals or metal oxides can be coated or formed into composites with the high surface area, relatively low aspect ratio graphene. If the added particles are larger than the graphene, they are coated with graphene, and if they are about the same approximate size, a nano-composite forms. The nanocomposites are useful for producing electrodes, especially for battery and supercapacitor applications.

  • Publication number: 20130273425
    Abstract: This invention relates generally to electrode materials, electrochemical cells employing such materials, and methods of synthesizing such materials. The electrode materials have a crystal structure with a high ratio of Li to metal M, which is found to improve capacity by enabling the transfer of a greater amount of lithium per metal, and which is also found to improve stability by retaining a sufficient amount of lithium after charging. Furthermore, synthesis techniques are presented which result in improved charge and discharge capacities and reduced particle sizes of the electrode materials.
