Abstract: Systems and methods are provided for on-the-fly playlist shuffling. There can be multiple ways to perform the shuffling. In one instance, the electronic device can organize a new playlist by sorting the media files based on a parameter. In another instance, the electronic device can organize a new playlist by shuffling the media files. In yet another instance, the electronic device can first sort the media files into groups of media files based on a parameter. The electronic device can then shuffle the media files within each group. In this manner, the media files can be randomized but only within each group. In all instances, the current media file can continue to play without any interruption. Finally, the electronic device can sort the media files based on the context of the media file that is currently playing.

Abstract: A process for synthesizing O-substituted oxime compounds, which includes (a) reacting an alkali metal or alkaline earth metal hydroxide compound and a solution of an oxime compound to form a first mixture including the alkali metal or alkaline earth metal salt of the oxime compound and water; and (b) adding an organohalide compound while stirring to the first mixture to form a second mixture including an O-substituted oxime compound, the alkali metal or alkaline earth metal salt of the oxime compound, water, unreacted organohalide compound and excess oxime compound. The second mixture is heated in the presence of an amount of water sufficient to react hydroxide with the unreacted organohalide compound to obtain an O-substituted oxime compound substantially free of unreacted organohalide compound.In a further embodiment, the O-substituted oxime compound can be hydrolyzed to the corresponding O-substituted hydroxylamine.

Abstract: A process is disclosed for the manufacture of 1-substituted amino-1-substituted thio-2 nitro alkenes of the general formula: (R1NH) (R2S) C.dbd.CR3 (NO2) wherein R1, R2, R3, may be same or different and may consist of hydrogen, alkyl, aryl or arylalkyl groups or combinations thereof. These alkenes are prepared by reacting a primary amine with a compound of sulfur in the presence of a primary catalyst to obtain a carbonimidodithioic acid salt which is converted to a corresponding ester which is thereafter reacted with a nitro compound in the presence of a secondary catalyst. 1-methylamino-1-methylthio-2-nitroethene is an important intermediate in the synthesis of Rantitidine and Nizatidine which are used as effective drugs in the treatment of peptic ulcers and associated gastrointestinal disorders.
