Abstract: The disclosure relates to automatic paint spray systems, typically but not necessarily of the electrostatic type, provided with color change means and facilities for recovery and re-use of the residual paint increment contained in the system at the start of a color change cycle.  The system includes an automatic color change cycle in a paint spray system, in which original paint is purged from the system by terminating the supply of the original paint and introducing purge fluids, including solvent and possibly also air.  The original paint is purged through a discharge line, on the downstream side of the paint spray devices, and is collected in a suitable receptacle, along with the purged solvent.  The system includes the ability of the discharge system to automatically separate and isolate the original paint from the new color paint, so that the purged paint may be collected in a segregated container and re-used. In a high volume application production operation, for example, it may be necessary or desirable to execute a color change cycle dozens of times in a typical production day, so that significant savings can be realized by enabling segregated collection and ultimate re-use of the purged materials.  In a typical commercial installation, savings in excess of $20,000 per year are to be anticipated.  Perhaps more importantly, the savings of materials is of great significance because of the limited availability from time to time of some paints and solvents, regardless of cost.

Abstract: LOW COST METHOD OF FLUIDIZING       CUPOLA SLAG (A) ABSTRACT OF THE DISCLOSURE      A method of fluxing and fluidizing the slag in a cupola by adding to the charge therein a fluxing material comprising, by weight percentage relative to the metal charge, 3-5% CaCO3 (limestone), 3-5% MgCO3 . CaCO3 (dolomite), and 1-2% Na2CO3 (fused soda ash).   This fluxing and fluidizing material is used for operating a basic cupola and is used in amounts ranging from about 7 to 12 by weight of the metal charge.  The flux material serves to remove impurities from the metal, and improve the combustion efficiency of the coke.  In an acid slag cupola, the flux will increase fluidity.  In a basic slag, a fluidizer serves to improve the fluidity of the slag, while offering no injurious by-products that would interfere with emission control elements, and additionally insures a lower cost fluxing material as compared to current basic operated cupola practices.

Abstract: AMMONIA SYNTHESIS                   ABSTRACT OF THE DISCLOSURE       An improved ammonia synthesis train utilizing hydrocarbon starting materials which are converted to hydrogen under superatmospheric pressure in a series of steps which include conversion of the hydrocarbons to hydrogen-carbon monoxide mixtures, shift conversion of the carbon monoxide to hydrogen and CO2, and removal of the CO2.  In such a system, reduction in process gas losses is achieved through an improved arrange-ment and integration of the shift conversion  and CO2 removal steps.  The carbon monoxide is first shifted in a series of shifts including a final low temperature shift; the bulk of the CO2 is removed by an essentially isothermal hot potassium carbonate CO2 removal system; the small residual amount of carbon monoxide is shifted to very low levels in a final low temperature shift; and the small amount of residual CO2 is then removed to very low levels in a second non-isothermal scrubbing system employing an aqueous solution of a chemical absorbent.  Methanation, compression and ammonia synthesis follows.  Losses of process gas in the methanation step and in the purge gas from the ammonia loop are sharply reduced with concomitant high thermal efficiency.

Abstract: Abstract A double fold automatic folding apparatus for selectively developing a second fold in a previously folded article.  The apparatus includes a reversible roller which, in a first direction of rotation, serves to bypass the se-cond folder and, in a second direction of rotation, oper-ates to divert a previously folded article into a position for engagement by the second folder.  After the article is diverted to the second folder, further reversal of the rol-ler to the first direction of rotation causes the roller to cooperate in the folding operation so that the double fold-ed article is drawn out of the second folder toward a con-veyor which transports the double folded article to an exit portion of the automatic folding apparatus.  Various elements may be optionally provided to assist in diverting the article toward engagement with the second folder and in rendering the operation of the apparatus more effective.
