Abstract: ABSTRACT      An improved hydrometallurgical method is provided for producing technical grade molybdic oxide from molybdenite concentrates.  According to this method, the molybdenite concentrates are leached in an acid medium having a nitric acid concentration between about 25 gpl and about 50 gpl and an initial sulphuric acid concentration of nil to about 750 gpl, under oxygen pressure of about 100 - 250 psig and at a temperature above 115°C so as to produce technical grade molybdic oxide having not more than 0.1% sulphur.  Then a liquid-solid separation of the reaction mixture is effected and the obtained leach liquor is recycled back to the leaching stage optionally after partial neutralization with a basic reagent.  The solid is washed and recovered as technical grade molybdic oxide and the wash waters are treated to remove recoverable  metal values therefrom.

Abstract: FORMING SEALED SEAMS IN MOISTURE BARRIERS FOR CABLES     Abstract of the Disclosure In the manufacture of a communications cable, a moisture barrier comprising a corrugated metallic tape is wrapped longitudinally about a cable core to form an over-lapped seam, with at least a portion of the moisture barrier which forms the seam being precoated with an adhesive mate-rial.  Heat is applied to at least the portions of the moisture barrier which form the seam while the portions are maintained spaced apart to permit a stripe of adhesive material in molten form to be introduced into the seam. Then the enclosed cable core is advanced between coacting rollers which apply forces to the moisture barrier to cause the spaced apart portions to engage each other with the stripe filling the spaces between associated corrugations to form a reliably sealed seam.  A longitudinally extending mandrel supports the barrier during the application of the forces to preserve the configuration of the enclosed core and to prevent damage to the core or the moisture barrier.

Granted: 1979-10-30
Abstract: ABSTRACT OF THE DISCLOSURE Fluids are injected into porous strata for many purposes. These include, for example, well stimulation, secondary-type oil recovery, mobility control, regulation of formation "wetness" and regulation of the encroachment of fluids. Fluids used for the above purposes are readily selected using nuclear magnetic resonance (NMR) measurements in the laboratory to measure the interaction between the fluids being injected into the reservoir rock and the in situ fluids or between injected fluids and the porous material. NMR measurements are taken for each component of sample fluids proposed to be injected in the reservoir for a desired purpose, or the sample fluid per se and each of the in situ fluids.  NMR measurements are then taken of the interaction between the nuclei of sample fluids injected, the reservoir rock, and the nuclei of fluids in situ.     If the injected fluid is to be used for some purposes, for example, well stimulation or secondary-type oil recovery, the fluids are selected which interact least with the rock and with in situ fluids.  If the wetness of the reservoir is to be changed, then the fluid is selected which interacts well with the reservoir rock.  If a material is to be precipi-tated or formed in situ, the fluid is selected which interacts well with either the reservoir rock or the formation fluids. Additionally, the best combination of components for a particular fluid to be injected can also be determined using NMR, preferably pulsed, detection devices.
