Abstract: The present invention provides a process for detecting and enumerating Campylobacter jejuni in an environmental sample. The present invention further provides a process which can distinguish antibiotic resistant strains of Campylobacter jejuni from wild-type strains, in particular, antibiotic-resistant strains resistant to high levels of ciprofloxacin. Both processes use PCR primers which flank a target sequence unique to Campylobacter jejuni in combination with one or more dual-labeled oligonucleotide probes complementary to the target sequence wherein the dual-labeled probes enable detection of PCR amplification by fluorescence detection means.

Abstract: A process for purifying calcium carbonate ore by the removal of silicate impurities from the ore by reverse flotation. The process achieves high yields and low Acid Insoluble content of the calcium carbonate product by employing novel collectors. These novel collectors which characterize the invention comprise organo-nitrogen compounds including hydroxypropylated quaternary ammonium compound, unsymmetrical dialkyl dimethyl quaternary ammonium compounds and dialkyl hexahydropyrimidine compounds.

Abstract: A process for purifying calcium carbonate ore by the removal of silicate impurities from the ore by reverse flotation. The process achieves high yields and low acid insoluble content of the calcium carbonate product by employing novel collectors. These novel collectors which characterize the invention comprise organo-nitrogen compounds including propoxylated quaternary ammonium compounds, unsymmetrical dialkyl dimethyl quaternary ammonium compounds and dialkyl hexahydropyrimidine compounds.

Abstract: Comminuted coal-oil mixtures are provided which may be maintained in a homogeneous state by the addition of a polyethoxylated, straight chain aliphatic quaternary ammonium compound corresponding to the formula: ##STR1## wherein R.sub.1 and R.sub.2 are each aliphatic groups having from 8 to 22 carbon atoms, wherein y and z are integers having a value of 1 or greater, the sum of y and z being between 2 and 15, and wherein X is an anion selected from the group consisting of CH.sub.3 COO.sup.-, Cl.sup.-, BO.sub.3.sup.-, and (CH.sub.3).sub.2 SO.sub.4.sup.-.

Abstract: Compositions containing ether diamine and salts thereof with N-acylsarcosines are disclosed. The ether diamine salts of N-acylsarcosines have the formula:[R.sub.1 O(CH.sub.2).sub.3 NH(CH.sub.2).sub.3 NH.sub.2 ].[HO.sub.2 CCH.sub.2 (CH.sub.3)NOCR.sub.2 ]wherein R.sub.1 is an aliphatic group containing from about 6 to about 18 carbon atoms and R.sub.2 is an aliphatic group containing from about 8 to about 18 carbon atoms. Also disclosed are fuel oil compositions containing said ether diamine and salts thereof, and a method for inhibiting corrosion utilizing said ether diamine salts.
