Abstract: ABSTRACT OF THE DISCLOSURE             Freshly dredged gravel is washed free of loamy and organic impurities while being continuously conveyed through a wash zone which includes a delivery chute and a plane endless conveyor band entrained in a direction opposite to that of the material delivery.  The conveyor band is mounted in a housing which includes side walls closely adjacent the lateral edges of the conveyor band and a hopper below the conveyor band.  The conveyor band is trained over a vertically adjustably mounted drive roller and a tensioning roller defining an upper and a lower course of the conveyor band therebetween.  Two additional rollers are arranged in vertical alignment and between the first-named rollers, a lower one of these rollers guiding the lower conveyor band course and an upper one of these rollers being vertically adjustably mounted and arranged to depress the upper conveyor band course to form a basin in the wash zone to which the chute delivers the granular material.

Abstract: ABSTRACT OF THE DISCLOSURE     Dry wood pulp is prepared by thermomechanically pulping wood chips and drying the pulp so formed by contacting it with a gas at a temperature of 300-600°C in or  at the entry of a high turbulence mixer through which the pulp and hot gas pass and which exerts a shearing action on the pulp to separate fibre bundles in the pulp.  The ratio of moisture to dry wood solids is maintained at less than 5:1 throughout the process.          The pulp is suitable for use as fluffing pulp or can be used to directly feed a dry forming paper-making or board-making process.

Abstract: Abstract of the Disclosure A process for the separation and selective recovery of platinum and palladium values from an acidic aqueous medium which comprises contacting the medium with a mixed organic extraction reagent comprising a water immiscible organic solvent having dissolved therein an organically substituted secondary amine compound capable of forming complexes of platinum and palladium that are preferentially soluble in the organic solvent and whereby the contacting results in creation of an organic extract phase and an aqueous raffinate phase.          After phase separation, palladium is selectively recovered-by contacting the organic phase with an aqueous solution of an acidified reducing agent.  Platinum is separately recovered by contacting the organic phase with an aqueous alkaline solution.  The process may be employed as a method for concen-trating solutions of platinum or palladium.

One of the connectors projectingly holds the bared fiber tips from one cable in a predetermined pattern at its mating end. The other connector internally holds the bared fiber tips of the second cable in an abuttment region, and freely accommodates the projecting fiber tips from the first connector upon mating therewith.              The second connector additionally includes a plurality of transversely displaceable finger-like elements extending from the outer connector project into respective channels within the abuttment region to securely align the abutting fiber tips within the channels when transversely displaced.     Means for displacing the jacket-engaging and fiber-engaging finger-like elements are provided in the form of sleeve members concentrically mounted about the connectors.  The inner walls of the sleeve members engage outwardly extending portions of the finger-like elements to transversely displace them into a substantially flush relationship with the outer connector peripheries.

Abstract: C13-55-0385 and -0386A*S Combination for Foreign Filing CROSSLINKED CRYSTALLINE POLYMER     FOR COOLING AND HEATING                    ABSTRACT OF THE DISCLOSURE          The invention relates to a method for storage and recovery of heat from crosslinked crystalline polymer. Usually the polymer will be in the form of a fixed bed of polymer pieces, however, fluidized or moving bed pieces are also operable in the method by circulating a heating or cooling fluid through the bed.  The polymer can also be in other form than pieces for the heating or cooling operation, i.e., sheets of polymer, long fibers either solid or hollow in a heat exchanger, or the heat exchanger can be molded from the polymer provided suitable passages for passage of heat exchange fluid.  The fluid can be either a gas or a liquid which has no appreciable solubility for the polymer, air and ethylene glycol being suitable for use when poly-ethylene is the polymer, and water can be used as the fluid provided sufficient pressure is applied to keep the water in liquid form.  More particularly the invention relates to crystalline polyethylene pieces having optimum crosslinking for use in storage and recovery of heat.  Crystalline polymer pieces are described which retain at least 70% of the heat of fusion of the uncrosslinked crystalline polymer and yet are sufficiently crosslinked for the pieces not to stick together upon being cycled above and below the melting point of said polymer, preferably at least 80% of the heat of fusion with no substantial sticking together.
