Abstract: A color correction system contains a plurality of color channels which each contain a dichroic mirror and an electro-optical modulator. An unpolarized light source shining through a color transparency serves as the input to each channel, and each color is individually controlled by the electro-optical modulator in its respective channel. The colors of each channel are then recombined after correction. In another embodiment of the invention, each channel further includes mono-color film storage means as black and white film storage means to store the color image of the particular channel on such an inexpensive film for subsequent reconstruction as a picture of different color than the film color. In a further embodiment, a plurality of separate colors of the same color image are stored on spaced regions of a given frame area of a mono-color negative, especially of a black and white negative, along with verbal information which is to be projected with the corresponding color image.

Abstract: The invention resides in a process for restoration of nickel-cadmium batteries which are rechargeable. The battery is submersed in boiling water and is maintained therein for a period of time of approximately 15 to 20 minutes. The battery is removed from the boiling water and is immediately cooled to approximately room temperature. Preferably such cooling is effected by submersion of the battery in water at a temperature of from 45.degree. to 50.degree. F. in which water bath the battery is permitted to cool for a period of approximately 20 minutes. The battery is then in condition for electrical recharging.

Abstract: Briquettes of specified geometry and composition are produced to serve as feed material or "burden" in a moving-burden gasifier for the production of a synthesis or fuel gas from organic solid waste materials and coal, including especially, the so-called "caking" coals, as in the process of copending application number 675,918. The briquettes are formed from a well-blended mixture of shredded organic solid wastes, including especially, municipal solid waste (MSW) or biomass, and crushed caking coal, including coal fines. A binder material may or may not be required, depending on the coal/MSW ratio and the compaction pressure employed. The briquettes may be extruded, stamped, or pressed, employing compaction pressures in excess of 1000 psi, and preferably in the range of 2000 to 10,000 psi. The briquettes may be circular, polygonal, or irregular in cross-section; they may be solid, or concentrically perforated to form a hollow cylinder or polygon; they may be formed into saddles, pillows or doughnuts.

Abstract: An improved method for the recovery of para-aminophenol from crude solutions thereof such as obtained by the catalytic hydrogenation of nitrobenzene in an aqueous acid reaction medium. The method comprises neutralizing the cold, acidic solution containing the crude para-aminophenol whereby a very fine fluffy para-aminophenol precipitates. When an aromatic amine selected from the group consisting of aniline, mixed toluidines, ortho-toluidine, mixed xylidines, and mixtures thereof is admixed therewith an upper layer containing the para-aminophenol suspended in the aromatic amine forms when allowed to settle. A clear lower layer containing about 70 to 90% of the ammonium sulfate solution is separated and discarded. The upper layer which contains the aromatic amine and the para-aminophenol can be used as a source of para-aminophenol for producing para-aminophenol derivatives such as diaryl para-phenylenediamines.

Abstract: The strains, PS 64-103; PS 24-44; and PB 33-48 are mutation products of the perfect fungi Polyporus squamosus and Polyporus brumalis and are characterized by the fact that in a liquid nutrient medium they tend to form hiffs, colonies and secondary spores, subdividing in geometric progression with rapid growth which varies in speed, depending on the seeding material ratio in a period of from 6 to 36 hours. The nutrient medium in which the mycelium is developed is quite simple in composition and comprises three components, i.e., 4-5% of molasses; 0.2% of NH.sub.4 NO.sub.3 ; 0.12% of KH.sub.2 PO.sub.4 and 0.04% of vegetable oil as foam suppressant. The strains assimilate from 50 to 60% of a given amount of saccharoses, accumulating to 1 to 1.2% of dry biological mass.The fungi mycelium can be adapted as a food product and is also used as an additive to various meat and other food products, i.e., sausage, minced meat, soft and smoked cheeses, vegetable canned food, soups, and bread and other bakery products.

Abstract: Ammonia converter for radial flow through two catalyst beds has a central heat exchanger mounted centrally in one of the beds. The process stream of synthesis gas is obtained by combining inside the converter separate feed streams: a shell stream serving to cool the converter shell, an exchange stream serving to cool the central heat exchanger, and a by-pass stream for final adjustment of the temperature of the process stream. The process stream passes in succession radially through the first catalyst bed in inwards direction through the central heat exchanger for being cooled, and radially through the second catalyst bed.

Abstract: The invention concerns a pulverulent, free-flowing monoglyceride based additive for use in the preparation of farinaceous and starch-containing products such as bread, macaroni, spaghetti, noodles and extruded snack products; this additive has been obtained by spray-cooling a substantially dry mixture containing the monoglyceride in molten condition together with at least one phosphatide, preferably lecithin and especially preferred soybean lecithin so that the individual particles will contain the monoglyceride and the phosphatide in substantially constant proportion. The product gives almost as good baking performance or performance in other heating processes for the dough into which it is incorporated as does a so-called monoglyceride-hydrate and has the further advantage of improving the flowing and packing properties of the pulverulent mixture.
