  • Publication number: 20150328481
    Abstract: The present disclosure describes improvements to personal heating that can raise the temperature of a target (e.g., a human) to maintain comfort, but at much less operating costs of conventional heating devices, e.g., space heaters. The embodiments describe devices (and system and methods) that utilize an energy beam (e.g., having a wavelength in the infrared spectrum) that changes the temperature of the outer layers of skin on a human. These embodiments offer an individualize solution to personal heating at relatively low energy consumption.

  • Patent number: 8399581
    Abstract: Metallocene catalyzed polyethylenes are found to have improved physical properties, improved processability and improved balance of properties. Surprisingly, there is a direct relationship between MD shrinkage, and MD tear. Additionally, MD tear is greater than TD tear, and MD tear is also greater than intrinsic tear. MD tear to TD tear ratios are above 0.9, and dart drop impact is above 500 g/mil. The polyethylenes have a relatively broad composition distribution and relatively broad molecular weight distribution.

  • Publication number: 20070041818
    Abstract: An apparatus for picking lumber pieces from the ground for example for removing support lumber used during laying of a pipe line comprises a tracked vehicle to which is attached a frame carrying a transport conveyer along the side of the vehicle inclined forwardly and downwardly toward the ground. A picking assembly is provided at the front of the conveyor and alongside the vehicle for lifting the pieces. This includes a front picking roller and a movable outer side blade which is inclined outwardly to the outer side of the picking roller and can be pivoted inwardly to close around the front of the picking roller to squeeze the lumber pieces to force them onto the conveyor.

  • Patent number: 7141632
    Abstract: The present invention provides polymerization catalyst compounds, catalyst systems including these catalyst compounds, and to their use in the polymerization of ethylene and at least one comonomer. In particular, the invention provides a catalyst system comprising a poor comonomer incorporating catalyst compound and a good comonomer incorporating catalyst compound. Preferably, the low comonomer incorporating catalyst compound is a metallocene containing at least one substituted or unsubstituted fused ring cyclopentadienyl based ligand which is substantially directed to the front of the molecule, contains a long bridging group, or which contains a methyl substitution pattern which correlates to poor comonomer incorporation. The invention also provides methods of selecting the poor comonomer incorporating metallocene to pair with the good comonomer incorporating metallocene to produce polymers that are easy to process into a variety of articles, especially polyethylene based film, having enhanced properties.

    Abstract: An apparatus for picking, conveying, stacking and bundling lumber pieces from the ground for example for removing stacked support lumber during laying of a pipe line comprises a tracked vehicle to which is attached a frame carrying a transport conveyer along the side of the vehicle forwardly and downwardly toward the ground. At the forward picking end is provided a picker roller for lifting the lumber pieces from the ground. On one side of the picker roller is provided a drive conveyer which is generally vertical and operable in forward and reverse direction to orient the pieces. On the side opposite to the drive conveyers provided a vertical blade with a rearwardly inclined inner portion which blade can pivot inwardly to push the lumber pieces toward the drive conveyer and to enclose and squeeze the pieces to a position inward of the side of the conveyer.
