Abstract: The panelized roof sheathing construction system includes a plurality of panels attached to a building frame structure in substantially abutting relationship. Each panel includes a water resistant barrier layer secured atop the outward facing surface of the panel. The water resistant barrier layer includes a skid resistant surface. Joints between panels are sealed by strips of water resistant tape or the like. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners.

Abstract: The invention comprises a wall sheathing barrier system having moisture permeability and simple improved installation method. The system comprises adjoined structural panels. Each panel has an overlay paper bonded permanently to the structural panel, which provides a moisture permeable barrier and a textured skid-resistant surface. The skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. Further, the seams of adjoining panels are sealed with a sealing means to complete the moisture barrier.

Abstract: Disclosed is a wood panel comprising bamboo strands cut from the inner portion of the bamboo culm.

Abstract: An improved process for the manufacture of gelling carrageenans from seaweed, wherein the seaweed is subjected to a heterogenous reaction for alkali modification of at least one carrageenan precursor to at least one gelling carrageenan followed by a recovery process. In the recovery process one or more lye recovery sections for the recovery of aqueous alkaline medium are used and there is reusing in the heterogeneous reaction of used aqueous alkaline medium after processing of incoming seaweed and for each recovery section there is reusing of at least part of the used lye recovery solution to compensate for the deficiency of alkaline medium as a result of the heterogeneous reaction.

Abstract: Phosphate free, Er/Yb co-doped borosilicate glass compositions and optical devices made from said compositions are disclosed; said compositions comprising, for 100 parts by weight of: 60 to 70 parts by weight SiO2 or SiO2+GeO2 with SiO2 always being greater than 40 parts by weight, 8 to 12 parts by weight of B2O3, 10 to 25 parts by weight M2O wherein M2O is an alkali metal oxide, 0 to 3 parts by weight of BaO, 0.1 to 5 parts by weight Er2O3, and from 0.1 to 12 parts by weight of Yb2O3 and from 0 to less than 5 parts by weight F; and within which, the boron atoms are of tetrahedral spatial coordination.

Abstract: According to one aspect of the present invention an optically active glass contains Sb2O3, up to about 4 mole % of an oxide of a rare earth element, and 0-20 mole % of a metal halide selected from the group consisting of a metal fluoride, a metal bromide, a metal chloride, and mixtures thereof, wherein this metal is a trivalent metal, a divalent metal, a monovalent metal, and mixtures thereof. In addition, any of the glass compositions described herein may contain up to 15 mole % B2O3 substituted for an equivalent amount of Sb2O3.
