Abstract: Acids, thickened with branched emulsion or suspension polymers of diallyldimethylammonium chloride are useful as oil well drilling and fracturing fluids for stimulating well production and in other applications, such as thickeners for cosmetics, paints, adhesives, textiles and printing inks.

Abstract: This invention relates to novel interphenylene 9-thia-11-oxo-12-azaprostanoic acid compounds, salts, and derivatives thereof. These compounds are exceptionally potent renal vasodilators and antihypertensives which are active when administered orally but which have a more specific type of biological activity than that of many of the natural prostaglandins and their synthetic analogs or derivatives.

Abstract: Electroconductive copolymers of diallyldimethylammonium chloride and at least 15 percent by weight acrylamide which exhibit improved solvent holdout.

Abstract: The invention relates to novel 2,2-dioxo-1,2,3-benzoxathiazines substituted in the benzene nucleus, as well as the 3,4-dihydro analogs thereof, useful as anti-inflammatory, antipyretic, analgesic agents.

Abstract: A vaccine against E. coli caused diarrhea is prepared from an isolate of the homogeneous heat-labile enterotoxin of human strain MB3353 of Escherichia coli, ATCC 31361, or of the porcine strain MB3708, ATCC 31362. The toxin, which is a protein, is a low molecular weight species of 10,000-13,000.

Abstract: Process for sealing phosphatized metal components to improve corrosion resistance and paint adhesion which involves coating said components with a zinc-containing sealant.

Abstract: An antigenic, immunogenic, non-toxic complex is obtained from the cell surface of N. gonorrhoeae.

Abstract: The levorotatory enantiomers of 3-halocyproheptadines and related compounds are antipyschotic agents and certain members of the group are novel compounds. Their dextrorotatory counterparts find utility as a source for additional levorotatory enantiomer.

Abstract: A method of preparing a compound of the formula: ##STR1## where Formula (I) may also have the structure of partial Formula (III); wherein, ##STR2## R' is hydrogen or methyl; R" is hydrogen or .beta.-methyl;R'" is .beta.-methyl or hydroxy;Z is (1) oxo;(2) .beta.-hydrogen and .alpha.-hydroxy; or .alpha.-hydrogen or .alpha.-hydroxyl and(3) (Y).sub.n Q where n=0 or 1, Y is a straight or branched hydrocarbon chain of 1 to 12 carbon atoms andQ is ##STR3## where R.sup.8 is, ##STR4## where the dashed bond replaces the 17.alpha. hydrogen; (6) cyano; or(7) tetrazolyl;and pharmaceutically acceptable salts of the above compounds;CHARACTERIZED IN THAT(I.) a compound of the formula: ##STR5## , where A has the meanings above except --CH.dbd.CH--, is (1) treated with an oxidizing agent at reduced temperatures to form the corresponding 5-oxo-3,5-seco-androstan-3-oic acid compound;(2) treating the product of step (1) with an amine of formula: R.sup.1 NH.sub.

Abstract: A novel, rapid acting drug combination comprising a phenyl benzoic acid compound and magnesium hydroxide. The combination results in earlier, higher plasma levels of the analgesic, anti-inflammatory drug.

Abstract: Substituted mercapto acid amides are prepared, and are useful as immunoregulants for correcting an imbalance of immune homeostasis, particularly as immunostimulants in the treatment of autoimmune and immune deficient diseases and disorders.

Abstract: Improved method of preparing 5-(2,4-difluorophenyl)salicylic acid and derivatives which favors formation of the desired end product over other undesired isomers, comprising the steps of(a) diazotizing an aniline compound,(b) treating the diazonium salt with a salicylic acid ester compound blocked in the 3-position with an easily removed blocking group, preferably cloro,(c) removing the blocking group, and(d) hydrolyzing the ester to form the acid final product.

Abstract: Gas streams contaminated with acid and acid precursor gases and vapors are purified by contacting the gas streams with activated carbon impregnated with sodium hydroxide.

Abstract: 3-Hydroxymethyl derivatives of cyproheptadine and related compounds are appetite stimulants and antihistaminic agents.

Abstract: An improved tamperproof container for lyophilized material wherein the container comprises a vial having flange about its opening. Below the flange, but spaced apart therefrom is a shoulder to define an indented neck therebetween. The opening is sealed with a pierceable stopper. An overcap extends over the flange and about the neck to form a skirt about the neck. The skirt has at least a portion thereof extending inwardly in gripping relation with the neck and limited in removal by contact with the underside of the flange whereby the cap cannot be removed without destroying its structural integrity.
