Abstract: ABSTRACT OF THE DISCLOSURE          A method of synthesizing hydrocarbons from a methane source which includes the steps of separating a mixture of lower alkanes to form a first fraction contain-ing predominately methane and at least one second fraction containing predominately C2+ alkanes; dehydrogenating the second C2+ fraction to form an effluent comprising C2+ olefins; contacting the methane fraction with an oxide of a metal which oxide when contacted with methane at between about 500° and 1000°C. is reduced and produces higher hydrocarbon products and water; and oligomerizing the C2+ olefin fraction and the methane contacting effluent to produce higher hydrocarbon products.  Also disclosed is a method of synthesizing hydrocarbons from a methane source which includes the steps of contacting a methane with a reducible metal oxide, recovering ethylene from the effluent of the contacting and oligomerizing the ethylene to produce higher hydrocarbon products.

Abstract: APPARATUS AND PROCESS FOR AUTOMATICALLY    DETERMINING FAT CONTENTS OF FOODS          ABSTRACT OF THE DISCLOSURE:        Apparatuses and processes are described for the automatic determinations of fat contents of foods, such as dairy products, e.g., milk, wherein automatic density and solids content determining apparatuses are employed, together with a computer, to determine the fat contents of food samples being tested.  The density determining apparatus is preferably one which is electromagnetically excited to vibrate at its natural resonant frequency, so that from the change in such frequency, compared to a control, the mass of the sample may be determined.  The means for measuring the solids content is preferably an automatic volatility computer in which electromagnetic radiation (microwave energy) is employed to drive off the volatile material (usually mostly water) in the sample, which is automatically weighed before and after such volatilization.  Preferably, a microcomputer in the automatic volatility computer is employed to compute fat content from electronic feeds to it from the density and the solids content determining apparatuses.  By use of the described apparatuses and processes rapid determinations of fat contents of materials may be made, facilitating modifications of production procedures to provide products of desired fat content, thereby preventing the production of off-specification materials and avoiding producing over-specification products which might otherwise be manufactured to avoid non-compliance with requirements for minimum fat contents of products.

Abstract: ABSTRACT OF THE DISCLOSURE       A composite glass/plastic ophthalmic lens is disclosed.  The lens consists of a thin layer of glass, preferably photochromic, adhered to the front of a plastic layer by a highly elastic adhesive.  The rear surface of the glass has a different radius than the front surface of the plastic so that the space between the lenses forms a tapered gap which is filled by the elastic adhesive.  The edge thickness of the elastic adhesive is sufficient to insure that the increase in diameter of the plastic layer with respect to the diameter of the glass layer due to differences in the thermal expansion characteristic of the glass and the plastic will not damage the composite lens even over a temperature range greater than 300°F.  The glass layer is shaped to have a power which compensates for differences in the index of refraction of the glass, adhesive and plastic layer, and which compensates for the optical powers produced by the tapered adhesive layer, so that the composite lens can be finished to prescription as though it were an all-plastic lens.

Abstract: USING OXYGEN FOR LEACHING             ABSTRACT OF THE DISCLOSURE Metal bearing ore, such as gold ore or silver ore, is subjected to a leaching action utilizing a cyanide solution liquid containing a large amount of oxygen.  The ore is slurried to form a liquid slurry (flocculating material and fibers may be added to lock the particlized ore in a stable network in the slurry) and is passed downwardly in a leaching reactor.  The cyanide solution is deaerated, and then oxygen gas is introduced under pressure to the cyanide solution, and preferably is mixed into the solution utilizing an in-line mixer downstream of a pump, to essentially saturate the cyanide solution with oxygen.  About 5-10 times the amount of oxygen can be provided in the liquid, in this manner, than if air were bubbled into the liquid.  The cyanide solution is introduced into the bottom of the leaching reactor, and passes upwardly countercurrent to the slurry flow.  The treated slurry is removed from the bottom portion of the vessel, and pregnant leaching liquid is continuously removed from the top of the vessel.
