Abstract: Abstract of the Disclosure Control of the synthesis loop pressure of an ammonia plant is accomplished by automatically changing the purge rate of the recycle gas to maintain optimum synthesis loop pressure.  The control logic of this inven-tion allows compressor speed to be set at a constant value and suction pressure to the first stage of the synthesis loop compressor to be main-tained by changing the purge rate of the recycle gas.  This allows the synthesis loop pressure to seek the highest possible value at the given feed rates of the synthesis gas and compressor speed assuring optimum compressor loading.         If the feed rate of synthesis gas is low, additional control of achieved by using the synthesis loop pressure signal or the concentration of inerts signal to vary the compressor speed.  A variation of this control logic for providing additional control where the feed rate of the synthesis gas is low is to use the synthesis loop pressure signal or the concentra-tion of inerts signal to manipulate the purge rate of the recycle gas and to use the suction pressure to the first stage of the ammonia plant synthe-sis loop to manipulate compressor speed.  Another variation of this control logic is to use the suction pressure to the first stage of the ammonia synthesis loop to vary the compressor speed and use either the synthesis loop pressure signal, the concentration of inerts signal, or the RPM of the compressors signal to vary the purge rate of the recycle gas.  All of these schemes for providing additional control where the feed rate of the synthe-sis gas is low allow the synthesis loop pressure to seek the highest possi-ble value at the low feed rate of synthesis gas assuring optimum compressor loading under all modes of operation.

Abstract: SHOE SOLE CONSTRUCTION                       ABSTRACT            A shoe sole having a tread defining a longitudinally orientated concavity with the lower extremities of the sole embodied in downwardly and outwardly disposed flex-ible lugs to cushion the foot against impact loads. An imaginary plane containing the lowermost points of inner and outer lugs, adjacent each side of the sole, inter-sects a projection of the sole edge at an acute angle.  Accordingly, the lugs may readily flex relative to other sole components for cushioning purposes. Rows of lugs spaced inwardly from the sole edges are of a lesser vertical dimension than the outermost lugs and serve to supplement cushioning. A web extends between some of the outer lugs to reinforce same against load deflection.      Further, the outer lugs may be of non-uniform lateral dimension at the heel portion of the sole.

Abstract: ABSTRACT        A whirlpool bath designed for use in hospitals and similar institutions has a tub which is raised sufficiently above the floor level on a recessed steel base so as to allow a vertical clearance for the use of trolleys and mobile patent-handling equipment to move patients toward and lower patients into the whirlpool bath.  The recess also makes work around the tub easier for attendants, providing toe room allowing the attendants to move closer to the tub.  Bumper strips and base moldings are attached to the whirlpool bath to protect the bath from damage from movable patient-handling equip-ment.  The sides and ends of the tub have removable panels fitting under the rim of the tub and clipping to a steel frame for rapid and easy removal and re-placement.  A capped opening in the built-in plumbing allows the water supply from a wall-mounted mixing valve to be admitted directly to the tub through the whirlpool fittings as an alternative to a spout or hose.

Abstract: ABSTRACT OF THE DISCLOSURE    Highly toxic metallurgical waste materials from copper smelting and/or refining operations are processed on a cyclic basis for recovering copper values therefrom while protecting the environment from contamination.  The waste materials, usually smelter flue dust and/or refinery sludge containing copper values and principally arsenic, bismuth, lead, antimony, and cadmium, as toxic values, with or without added sulfuric acid, are reacted in an autoclave in an overpressure atmosphere of O2.   The resulting solution, pregnant with copper and still containing a significant amount of arsenic, i.e. from about 0.5 to about 2.0 grams per liter, is subjected to copper cementation on metallic iron to recover copper and to provide iron values in the solution while substantially eliminating residual toxic constituents, surprisingly without the evolution of arsine gas.  The copper-barren but iron-containing solution is then recycled to the leaching step.  The cement copper precip-itate is smelted along with copper ore concentrates, while the solid residue from the leaching step is discharged to a tailings pond or the like as an environmentally safe, insoluble residue.

Abstract: Abstract of the Disclosure A system is disclosed for sealing a metal foil membrane on the end of a container such as a composite container using a rotating turret having a plurality of spindles in it with non-metal rotating heads on the splindles for pressing a closure and foil membrane against the container sealing surface and rotating the container-closure assemblies about the axis of the container as they are moved through a magnetic field produced by an induc-tion heating coil disposed at least partway around the turret. The container-closure assemblies may be moved through the magnetic field in less than one second to heat the sealing area of the foil membrane and metal foil liner in the container to the required sealing temperature while minimizing heating of the membrane beyond the area of sealing contact with the container. Either the foil membrane or container liner or both have a heat seal resin thereon which is softened or melted by the induced heata in the membrane and seals the membrane to the container when the container-closure assemblies are removed from the magnetic field.
