PROCESS FOR MAKING POLYSILOXANE EMULSIONS Disclosed is a method for producing emulsions from high viscosity polysiloxanes, bi-modal polysiloxane fluids, functional polysiloxanes and mixtures thereof. The method comprises forming a thick phase emulsion by blending a polysiloxane, at least one primary surfactant and water. To the blend, at least one secondary surfactant is added. The mixture is t...

The present invention relates to an improved method for the synthesis of omeprazole, comprising the steps of reacting 5-methoxy-2-[(4-methoxy-3,5-dimethyl-2-pyridinyl)-methylthio]-1H-benzi midazole with m-chloroperoxy-benzoic acid in a methylene chloride solution at a substantially constant pH of about 8.0 to 8.6; extracting the reaction mixture with aqueous NaOH; separating the aqueous phase from...

A remote-control system for closures with a movable hand transmitter with at least one transmission key, this transmitter generating and radiating directed coded control signals upon actuation of the transmission key of the hand transmitter. At least one first receiver unit is tuned to receive the control signals radiated from the hand transmitter and is arranged on a motor vehicle and triggers sw...

The articles are fed onto a conveyor belt, and move in two or more parallel rows to a collecting surface into which they are fed with an equal number of articles in each row, thus forming a horizontal array. Further articles move in two or more further rows to a further similar collecting surface in which a similar horizontal array of articles is formed. The first array is then moved as a unit by ...
