Abstract: An electrical system for generating arbitrary voltage waveform includes a power supply unit for providing a supply voltage to the electrical system. One or more charge pumps are in electrical communication with the power supply unit. Each charge pump generates a voltage. The electrical system also includes a plurality of switches, a first switch among the plurality of switches coupled between a ground and an output terminal, other switches among the plurality of switches coupled between the one or more charge pumps and the output terminal. A control circuit is in electrical communication with the power supply unit, the plurality of switches and the one or more charge pumps, and is operable to control the voltage generated by the each charge pump and the plurality of switches. Voltages from the one or more charge pumps additively result in a variable output voltage that generates an arbitrary voltage waveform.

Abstract: In a process of manufacturing screen material a metal matrix is subjected to an electrolytic metal deposition by using an electrolytic bath containing a brightener, the liquid of the bath being forced to flow through apertures in the cathode toward the anode. The metal deposits grow substantially perpendicular to the lands of the matrix and so form a screen having apertures of approximately the same size as the apertures of the original matrix. The screen can be removed from the matrix by previously coating the latter with a separating agent such as beeswax.An installation for performing the process of the invention comprises a perforated cathode as matrix being fixed to cathode fixing means, a perforated anode being fixed to anode fixing means and a pump for providing a forced flow of liquid through the apertures of the cathode toward the anode.
