Abstract: A thermogenic system based on exothermic chemical reactions for heating consumer-type products as dispensed from suitable packages. The system includes the redox reactions of hydrogen peroxide as the oxidant and as the reductant compounds of the general oxazolidine formula ##STR1## wherein R and R' may be the same or different and are selected from the group consisting of hydrogen, alkyl of from 1 to 4 carbon atoms, and substituted alkyl such as hydroxyalkyl e.g. hydroxymethyl. The effectiveness of the system can be enhanced by the addition of a catalyst selected from the group consisting of p-toluene sulfonic acid, iron filings, and iron salts of either the ferrous of ferric ions such as sulfates and halides thereof e.g. FeSO.sub.4 and FeCl.sub.3.

Abstract: The settling of finely-divided solids that are in suspension in an aqueous medium due to the presence of a colloidal argillaceous mineral is enhanced by adding a small but effective amount of an organic peroxide to the suspension. This invention is especially useful for treating aqueous suspensions of ultrafine clay and other materials resulting from the hydraulic concentration of an ore material, such as phosphate slimes.

Abstract: A clay slurry containing 50% or more of non-volatile solids comprising calcined kaolin clay and from 8 - 331/3% of hydrated kaolin clay based on the weight of the calcined clay. Additionally the slurry contains from 0.01% to 10% of a suspending agent such as bentonite clay, hydroxyethyl cellulose, methyl cellulose, carboxymethyl cellulose and a dispersant such as a non-ionic surfactant, an anionic surfactant or an alkanolamine.

Abstract: A method of setting keratin fibers which have been treated with a thiol reducing agent by treating said fibers with an oxazolidine.

Abstract: A method of controlling the growth of bacteria and fungi by applying to the environment inhabited by them a compound represented by the formula ##STR1## where R and R' are hydrogen, methyl, hydroxymethyl or ethyl and can be the same or different.

Abstract: Carbostyril derivatives useful as coccidiostats are prepared by reacting an ortho-halo benzaldehyde with a 2-alkyl-2-oxazoline, then heating at above about 200.degree. C thereby forming the carbostyril.

Abstract: In a process for treating raw kaolin clay to improve the color and brightness by treating the clay in an aqueous dispersion with sodium dithionite, the improvement consisting of treating the dispersion with hydroxylamine or salt thereof after the treatment with sodium dithionite is complete.

Abstract: A process for sealing glass to metal by applying a methylolated polyoxazoline to the surfaces of the glass and metal which are to be joined, applying a sealant to the oxazoline-coated surfaces, joining the glass and metal surfaces to be sealed and allowing the sealant to dry.

Abstract: Vinyl oxazolidines corresponding to the formula ##EQU1## wherein R is methyl, ethyl or hydroxymethyl, and R.sup.1 is hydrogen, methyl or ethyl and R.sup.2 is hydrogen, methyl or hydroxymethyl; or the oxazolidine can be the tris-oxazolidino derivative of 4-keto-9, 11, 13-octadectrienoic acid triglyceride (oiticica oil). The compounds have utility as dispersing agents in water-based paints.
