Title: Recovery of nitric acid soluble transition metals from sulfur and iron containing ores of the same
Inventor: POSEL JOHN G
IPC: C22B3/06
Filed: 1976-04-14
Granted: 1979-11-13
Abstract: Abstract of the Disclosure This invention relates to a method of recovering one or more metal values of the group consisting of copper, silver, nickel, cobalt ant zinc from a sulfur an iron containing ore of the metal or metals.  The method consists of intermixing the ore and at least a stoichiometric amount of nitric acid of about 30-50% by volume concentration to form an aqueous acid leach solution of the same.  The solution is heated to a temperature at or above the melting point of sulfur while the solution is contained under pressure in a relatively inert atmosphere.  The temperature of the solution is controlled to substantially solubilize the sulfur and the metal value or values in the acid soluble phase of the solution while substantially insolu-bilizing the iron values with respect thereto.  The iron values are separated from the acid soluble phase of the solution, and the metal value or values recovered from the acid soluble phase.  This process allows the metals to be solvent extracted from the liquor without the problem of lasting precipitates forming in the liquor and fouling the extraction process.

Abstract: ABSTRACT                  A container is disclosed of that type best suited for carrying air freight in wide bodied aircraft, made to the general specifications of an LD3 Igloo which is essentially a nominal five-foot cube, being extended along one direction perpendicular to the fusillage aircraft to slightly over six feet.  The subject container is molded of reinforced fiber-glass in a semi-monocoque construction, the door opening being a part of the original molded material.  The material is characterized by a plurality of layers of fiberglass and resin including matting, roving, and overlap matting; criss-crossed webbing being provided at the exterior beneath the overlay matting.  Each of the fiberglass members as well as the webbing aid separated by a layer of resin.  A rail is provided around the periphery of a support pallet having an upstanding container flange to which the fiberglass molded portion is secured.  In the method, a split mold is employed with one portion of the split mold being complimentary to the tapered end of the container.  The molds are coated with Teflon, the various layers of resin and fibergalss and the webbing being applied exterior thereto, and heated for curing from the inside.  Upon removal, the one portion of the mold which is rectilinear in configuration is first removed and thereafter the tapered portion.  Thus a mold can be used which is larger in its assembled form than the opening at the bottom of the enclosed container.  The door portion is then sawed out of one end, and framing means secured to the opening and the material which is removed becomes the material for the door.  Optionally, the mold sections can be provided with air holes so that air can be used in assisting to strip the molds from the container.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a delay equalizer for a circular wave guide comprising a circular input wave guide and a circular output wave guide having the same diameter as the input wave guide and being connected to the input wave guide by a common end, the axes of these two wave guides meeting at an angle.  The delay equalizer also comprises a first progres-sive reflector constituted by a circular wave guide whose input diameter is equal to that of the input wave guide and the output wave guide and whose cross-section decreases from its input so that the waves which enter the first progressive reflector will be reflected after having travelled along a path which is longer for increasing frequency, this first progressive reflector being placed in the line of the input wave guide beyond the common end to which it is connected by its input.  Also, there is a second progressive reflector identical to the first and placed in the line of the output wave guide beyond the common end to which it is connected by its input.  Finally, there is a plane semi-reflecting plate of the "quarter wave" type occupying the in-terior cross-section of the wave guides at their common end and being disposed so that the axis of the input wave guide will be symmetrical to the axis of the output wave guide in relation to this plate, the material and the thickness of this plate being chosen so that it will let pass half the energy of the waves which it receives with a phase shift of a quarter of a wavelength and so that it will reflect the other half of this energy.
