  • Publication number: 20080275149
    Abstract: Methods of controlling the durability of and/or the amount of air in concrete formulations that include combining cement, water, and optionally aggregates, admixtures and/or additives to form a cement mixture; and adding prepuff particles to the cement mixture to form a concrete formulation. The prepuff particles have an average particle diameter of from 0.2 mm to 3 mm, a bulk density of from 0.015 g/cc to 0.35 g/cc, an aspect ratio of from 1 to 3, and a smooth continuous outer surface. The cured and hardened concrete formulation typically has a relative dynamic modulus of at least 70% determined according to Procedure A of ASTM C666 (2003). The amount of air in the concrete typically increases over the amount of air in similar formulations not containing prepuff particles, as determined according to ASTM C231, based on the volume percent of prepuff. The concrete formulations can be used to make articles.

  • Publication number: 20080269363
    Abstract: Interpolymer resin particles comprised of 20% to 60% by weight of uncross-linked polyolefin e.g. polyethylene, polypropylene, and from 40% to 80% by weight based on the weight of the particles of a vinyl aromatic monomer, e.g. styrene, that is polymerized in a suspension process to form an interpenetrating network of polyolefin with polymerized vinyl aromatic monomer particles and having a gel content of 0 to 1.5% by weight based on the weight of the particles for improved processability in end-use applications and improved ESCR properties. The interpolymer resin particles have a VICAT softening temperature from about 90° C. to about 115° C., and a melt index from 0.2 to 35.0 g/10 minutes (Condition G). The particles can be mixed with a blowing agent to form extruded foam articles, such as foam board, and can be used in extrusion, injection molding, rotomolding, and thermoforming processes to form a layer, e.g.

  • Patent number: 7442845
    Abstract: Ethers are cracked to olefins using a gamma-alumina catalyst in the presence of ammonia. The use of ammonia improves the selectivity to linear alpha olefins in comparison to cracking reactions in the absence of ammonia. The use of ammonia is convenient in comparison to known processes which employ alumina which as been treated with an amine. A preferred process produces octene-1 from 1-methoxyoctane.

  • Publication number: 20080250739
    Abstract: Foamed plastic structures that include one or more foamed plastic bodies containing a polymer matrix that includes one or more polymers formed by polymerizing a monomer mixture formed by polymerizing a monomer mixture containing vinyl aromatic monomers using a polymerization initiator having a structure corresponding to: R(Y)n where R is a C2 to C32 linear, branched, and/or cyclic aliphatic and/or aromatic group that can also include one or more atoms selected from oxygen, nitrogen, halides, silicon and sulfur, Y is a group that can generate a free radical capable of initiating polymerization of the monomers in the monomer mixture; and n is from 2 to 6. The structures formed can include, as non-limiting examples, pallets, containers, stackable containers, produce boxes, seafood shipping containers, geofoam blocks, and insulated concrete forms.

  • Publication number: 20080248228
    Abstract: Disclosed is a produce package made from a gas permeable, non-perforated polyethylene film. The polyethylene film is made from a blend of a linear low density polyethylene and a high pressure low density polyethylene. The film has an absolute oxygen transmission rate that is greater than the weighted average of the absolute oxygen transmissions rates for film made from each blend component. Disclosed are polyethylene blends having densities above 0.910 g/cc that can be made into films with absolute oxygen transmission rates greater than 550 ccO2.mil/100 in2.24 hrs.

  • Patent number: 7417472
    Abstract: A multi-channel integrated circuit is provided in which each channel has an analog section and a digital section. Each channel of the readout chip employs low noise charge sensitive amplifier at its input followed by other circuitry such as shaper, pole-zero, peak hold, different comparators, buffers and digital control and readout. Each channel produces a self-trigger and a fast timing output. Channel-to-channel time differences are also recorded. Integrated circuit also provides a large dynamic range to facilitate large range of applications. The trigger threshold can be adjusted to provide energy discrimination. The chip has different, externally selectable, operational modes including a sparse readout mode in which only the channels which have received signals greater than a preselected threshold value are read out. The sparse readout mode results in increased data throughput, thus providing fast data acquisition capabilities.

  • Patent number: RE40484
    Abstract: A tripper/hopper car rides on a conveyor via four wheel tires running on T-section rails, with respective hold down wheels riding adjacent the underside of the rails and respective caster side wheels riding adjacent the vertical edges of the T-rails. Each wheel tire is driven by a motor drive unit employing a shaft-mount gearbox with a motor brake that utilizes the reduction of the drive gearbox to increase the effective braking torque developed. A pair of caliper-type brakes is further provided for redundancy.
