Abstract: A space-efficient wall mounted bicycle hanger. The hanger comprises a linkage that includes a wall mount, a folding extension arm that is foldable in a horizontal folding plane, and a bicycle support pivotally connected to a distal end of the foldable extension arm. The support is rotatable in the horizontal folding plane for yaw angle adjustment of a supported bicycle and can also be rotatable in a vertical tilting plane for pitch angle adjustment.

Abstract: Methods for the preparation of pharmaceutically acceptable organic or inorganic salts of 5-methylpyrazinecarboxylic acid-4-oxide esters including tris(hydroxymethyl)aminomethanol, N,N-dimethylethanolamine, N-methyl-D-glucamine, L-Lysine, L-arginine, Na, K, Ca and Mg. The esters of 5-methylpyrazinecarboxylic acid-4-oxide are oxidized in aqueous hydrogen peroxide at a pH of 2.5 to 7 in the presence of a catalyst selected from the group consisting of sodium tungstate, tungstic acid and ammonium heptamolybdate. The salts are formed by saponification of the esters followed by alcohol precipitation, or by reaction with a metal trimethylsilanoate, or by the reaction of organic bases with the saponified acids.

Abstract: Methods for the preparation of pharmaceutically acceptable salts of 5-methylpyrazine-carboxylic acid-4-oxide by using the oxidizing agent OXONE® for the N-oxidation of C1-4 methylpyrazinecarboxylic acid esters. The pharmaceutically acceptable salts are then formed by the saponification of the esters followed by alcohol precipitation.
