Abstract: A combination of laminated materials which provides a non-foil packaging material (12) having enhanced sealability employing RF electric energy. In this combination, the relatively low, and otherwise inadequate, RF susceptibility of one or more layers of the laminate is enhanced to a value which provides fast and efficient heat sealing of the laminate to itself. This enhancement is accomplished through the incorporation within the laminated (12), in a selected order of lamination, of one or more layers (40) which tend to direct the heat generated by one or more inner layers (28) to that outer layer (14) of the laminate which is to be heated to an effective heat sealing temperature. Ethylene vinyl alcohol (EVOH) has been found to be particularly suitable as a primary RF susceptor in the combination of the present invention. A method for RF electric energy heat sealing of the packaging material is disclosed.

Abstract: A process for separating printing ink from recycled paper fiber (20) includes the steps of repulping recycled paper furnish with water in a rotary mixer (10) for about 5 minutes at a consistency of 6 % to 18 % with a mixing element (16) having a top speed no greater than 2,000 ft/min. This first stage repulping and mixing is followed by a second mixing stage of 20 to 45 minutes with a mixing element tip speed 2,500 to 4,000 ft/min. Agglomerated contamination particles in the resulting slurry are removed by centrifugal cleaning and slot screening (18).

Abstract: The specification discloses a flow distributor (54, 56, 58, 60, 62) for distributing a flow of fluid to a bed of particles in a fluidized bed reactor. The flow distributor (54, 56, 58, 60, 62) comprises a plurality of spaced apart discharge conduits containing exit openings for distributing the flow of fluid into the bed of particles generally across the width of the reactor from a plurality of spaced apart locations. Flow diffusers are located in the conduits upstream of the exit openings to provide multiple, spaced apart, generally parallel, flow streams within the conduits which expand and merge together as they approach the exit openings to produce a merged flow stream extending substantially across the width of each conduit prior to discharge of the flow into the reactor.

Abstract: The present invention provides for improvements in the preparation of cellulosic wood pulp for use in papermaking, and specifically to enhancement of the quality of a pulp which has been subjected to a chlorine-based bleaching agent, by subjecting the chlorinated pulp to ozonation prior to an extraction stage in the bleaching sequence. The improved pulp of the present invention includes reduction of total organically bound chlorine residues in the wood pulp and adsorbed organic halides (AOX) in the effluent, and has good brightness and viscosity. The advantages of the present invention may be accomplished by means of a bleaching sequence that employs as few as four stages, namely DZED or DcZED with attendant relatively lower capital investment than heretofore possible.
