Abstract: POLYMERIC SHEETS               Abstract of the Disclosure A polymeric sheet, useful as a burn dressing, that has an ultra-thin pinhole-free polymeric membrane on one side, formed from two or more layers of polymer, and a fabric texture on the other side, formed from a fabric-textured sheet, embedded in the polymer.  The polymeric sheet features physiologic properties similar to human skin, excellent drapability characteristics, and recessed portions which provide a reservoir for debris from a burn.  The poly-meric sheet can be made by:  (1) applying two or more layers of polymer to a forming surface; (2) partially embedding a sheet having a fabric texture in the top layer of polymer;          (3) curing the polymer to form a composite of the fabric-textured sheet and polymer; and (4) separating the composite from the forming surface.

Abstract: ABSTRACT OF THE DISCLOSURE        A bulk material handling and reclaiming device of a nature that can be added to or substituted in known reclaiming installations.  Bulk material such as coal delivered by a con-veyor from a mine normally is delivered by a conveyor in large quantities during the period of mine operation to storage areas where it is stacked in mounds covering circular or rectangular storage areas.  The new recliner has a cage on which a plural-ity of sets of buckets are moved in either direction by chains to which the buckets are pivoted, the chains endlessly sur-rounding the cage.  The chains are driven to move in either di-rection in channel tracks.  The cage is nonrotatably supported and bodily moved in straight or arcuate paths in either direc-tion toward one or another end of stacked bulk material in storage areas.  The buckets dump the bulk material, scooped up by the buckets in either direction of buckets movement or cage travel, at the top of the cage into a belt conveyor mounted and moving along the axis of the cage to one end thereof to dis-charge the reclaimed bulk material to further transport means to deliver the same to a place of use.

Abstract: ABSTRACT       AUTOMATIC AND ADAPTIVE DIGITAL NONLINEAR            DECISION FEEDBACK EQUALIZER         A method and apparatus for equalizing a scanned noisy digital signal with an automatic and adaptive decision feedback equalizer comprising a nonrecursive part and a recursive part.A switch is disposed in the feedback loop of the equalizer between a decision device and the recursive part of the equalizer for allowing the determination of a step size factor. For this purpose the switch is in such a position that a reference signal can be fed into the feedback loop  and at the same time the gradient coefficients are fed to a device for setting the filter coefficients the gradient coefficients are determined at that point in time  where the switch was set to the other switch setting. The number of the required interation intervals to approaching the minimum of the equalization error can be decreased by employing the method of the present invention. In addition, the filter configuration can be employed in a multiplex operation.

Abstract: SYNCHRONIZING SYNCHRONOUS MOTORS PRIOR TO CLUTCH CLOSURE         ABSTRACT OF THE DISCLOSURE              In the inching of a grinding mill or similar apparatus which is driven by a pair of synchronous motors through fluid actuated clutches, the motors must be synchronized one with the other in order that the load be shared equally between the motors.  The apparatus of the invention connects the field supply to both motor fields and then it connects a zero frequency supply to the stator windings of both motors and ramps up or increases the amplitude of the low frequency supply.  This brings the rotors into synchronism without undue oscillation.  When the amplitude of the low frequency supply reaches a predetermined level, the clutches are closed or locked and the motors are connected to the load with the rotors synchronized.

The improved process is charac-terized by a reduction in solubility of the reduced aluminum metal as well as a smaller metal droplet size permitting closer anode-cathode spacing in the electrolysis cell and a lower electrical resistance.  The improvement comprises performing the electrolysis in an electrolyte consisting essentially of from 0.5 to 15 wt.% aluminum chloride, from 0.5 to 40 wt.% of one or more alkaline earth metal chlorides selected from the class consisting of magnesium chloride, barium chloride,  strontium chloride and calcium chloride,  from 10 to 90 wt.% lithium chloride and the balance sodium chloride.
