Abstract: 5 A hinge system for a waste bin, the waste bin having a bin body with an open top and a lid for covering at least some of the open top, the system including a hinge assembly for hinging the lid to the bin body adjacent the open top, such that the lid is rotatable between a closed position covering at least part of the open top and an open position exposing the open top, and a damper assembly for connection to the bin body and the lid, the damper assembly having a damping mechanism configured for generating resistance to movement of the lid towards the closed position and substantially less resistance to movement of the lid towards the open position.

Abstract: A lid assembly for hinged connection to a bin body with an open top, the lid assembly including a lid formed as a single layer of polymer dimensioned to cover the open top, and a reinforcing frame for attachment to a hinge at a rear edge of the open top, the reinforcing frame having reinforcing members extending from the hinge towards a front edge of the lid extending along a front edge of the open top when the lid is in a closed position, wherein the reinforcing members attach to the lid for rotating therewith about the hinge.

Abstract: A method of processing an exchange includes providing a solver/analyzer for determining a solution that includes at least one of a winning allocation and feasible allocations. At least one bid is received at the solver/analyzer, with each bid including at least one item and an associated price. Exchange description data (EDD) is associated with the at least one bid. The EDD is also received at the solver/analyzer. The processing of the at least one bid is modified in accordance with the at least one feature included in the EDD.

Abstract: A method for making dissolving pulp from cellulosic fiber. The fiber is treated with a 3-stage sequence having a first alkali extraction stage, a xylanase treatment stage, and a second alkali extraction stage. Having the xylanase treatment stage sandwiched between 2 alkali extraction stages results in the dissolving pulp exhibiting both a very low xylan content of about 2.6% by weight or less and a very low mannan content of about 1.5% by weight or less. The low contents of these 2 components cannot be achieved with comparison treatments of only an alkali extraction stage, only a xylanase treatment stage, or only 2 stages of a xylanase treatment stage and an alkali extraction stage.

Abstract: A method of treating a felt to remove contaminants therein comprises the steps of providing a felt used in transporting paper webs, preparing an enzyme solution comprising an enzyme selected from the group consisting of a cellulase, a hemicellulase, and mixtures thereof, applying the enzyme solution to the felt for a first predetermined period of time, rinsing the felt with water, applying a solution of sodium hydroxide to the felt to remove the enzyme solution, and rinsing the felt with water to remove the sodium hydroxide solution thereby removing the contaminants in the felt.

Abstract: Disclosed is a method of removing ink from xerographically printed paper. The method comprises pulping said printed paper in an aqueous slurry at a non-acidic pH to a consistency of about 8% or less. Next, added to the pulp slurry is a sufficient amount of long chain alcohol, the long chain alcohol having a melting point above room temperature, for a time sufficient with heating at a temperature sufficient, whereby an agglomeration of long chain alcohol and ink particles is formed. Next, the heating is stopped whereby the agglomeration solidifies into particles that settle to the bottom of the pulp slurry. Then, the agglomeration of solidified particles is removed from the pulp slurry thereby leaving a remaining slurry of deinked paper fiber and water. Optionally, the remaining slurry is subjected to flotation to remove substantially any remaining minute ink left particles behind after the agglomeration.
