Abstract: A photoactive ionization high-tension pulsator is provided between the distributor and the spark plug of a carburetor motor ignition system. The pulsator comprises tubular housing, electrodes disposed therein in spaced apart relationship, and a ring positioned on the inside wall of the tubular housing and being separated from the electrodes. The ring comprises a photoactive material responsive to break down between the electrodes for causing ionization of the gas, whereby to provide high-frequency current in the motor ignition system.

Abstract: A streaming vibrator with an uninterrupted rolling area and an unloaded blade. The vibrator has a housing with a cylindrical cavity defined therein. End plates laterally limit the cavity and support a central pipe having a periphery coaxial with a rolling area defined by the wall of the cylindrical cavity. A bore of the pipe is connectable to a source of pressurized fluid, and the pipe has an opening positioned between the end plates to provide communication between the bore and the cylindrical cavity. A freely rotatable scutching member formed as a hollow cylinder is positioned in the space between the central pipe and the rolling area. A blade extends through the opening in the pipe into contact with an interior wall of the scutching member to divide the cavity into two components. A plurality of channels are formed in the blade and oriented away from outlet openings formed in the end plates.
