Abstract: Disclosed is a process for preparing adiponitrile from acrylonitrile in an electrolytic cell. An aqueous electrolyte comprising acrylonitrile converts to adiponitrile in the presence of a solid anode and in the absence of a solid cathode. The cathode comprises gas plasma.

Abstract: A flow operated valve having a single inlet and multiple outlets. Flow of liquid is directed through an enclosed body from the inlet to a single one of said outlets in a repetitive sequence, the selected outlet being rendered operative in response to initiation and cessation of liquid flow at the inlet. The flow of liquid through such outlet is controlled by a hinged valve, which in turn is operated by angularly spaced projections located along a pivot shaft. A slide within the body is reciprocated perpendicular to the shaft during initiation or cessation of flow at the inlet. This reciprocating movement is converted to incremental pivotal movement of the shaft, which in turn opens and closes the outlet valves in a repetitive sequence.
