A plurality of batteries located in battery-operated devices by a charger through a distributor where there is no communication between the distributor and the batteries in the battery operated devices are charged in automated sequence in situ by a charger through a distributor where there is no communication between the distributor and the batteries, preferably using pulsed charge technology. In preferred embodiments the pulsed charge technology includes both forward and reverse pulses.

Method for sequentially charging batteries in situ

Electrodes are cured through application of modulated electrical signals. In preferred embodiments the signal comprises pulsed currents, and in particularly preferred embodiments the signal comprises a train of both forward and reversed pulses, with modulation of the duty cycle by pulse width modulation during the curing process.

Apparatus and methods for manufacturing electrodes

A delayed coker drumhead handling apparatus, which includes remotely operable trammel pivot apparatus to open and close the coke drum by moving the drumhead downwardly and laterally, such that the apparatus is especially suitable for use in areas of restricted clearance to the operating deck or otherwise confined space.
