Abstract: Housings are described that include snap fittings or connections that can be placed on portions of the housing to allow assembly of the housing in the field, without the need for assembly tools or welding. Reduced assembly time and cost, as well as the reduction/elimination of tooling costs for assembly tools and/or associated hardware can therefore be realized. Exemplary embodiments of the present disclosure can include a snap fitting with first and second portions, e.g., male and female portions, including a portion having a tab or clip punched out of a sheet and including a holding protrusion or portion, and another portion having an aperture or depression configured and arranged to receive and be held by the holding portion. Preferred embodiments can be utilized as light pole base covers.

Abstract: Tetranitromethane and other polynitrated methanes can be effectively removed from otherwise substantially organic-free nitric acid streams through the addition of substantially organic-free concentrated sulfuric acid and by, optionally, performing secondary operations such as sparging the mixed acid stream with a gas such as nitric oxide or with an oil.

Abstract: A method for making macrocyclic polyesters comprises the steps of supplying heat and contacting bis-hydroxyalkyl-terminated diesters or oligomers thereof with high boiling point solvents and esterification catalysts.

Abstract: Process for isolating macrocyclic polyester oligomers from impurities comprising the step of subjecting solutions of macrocyclic polyester oligomers to protonated molecular sieves.

Abstract: A method is provided for ortho-alkylating phenol by passing a mixture of phenol and methanol through a heated magnesium oxide catalyst. The magnesium oxide catalyst is made by calcining magnesium carbonate and thereafter further heating the calcined product in the presence of steam.

Abstract: Aqueous polymer microsuspensions having controlled particle size and narrow particle size distribution are prepared by a continuous process comprising the steps of (a) forming a heterogeneous composition having a discontinuous aqueous phase and a continuous polymer phase; and (b) converting the resulting polymer-continuous heterogeneous composition to a water-continuous heterogeneous composition.
